    Improvement of Automated Guided Vehicle's image recognition: Object detection and identification2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Automated Guided Vehicle(AGV) as a kind of material conveying equipment has been widely used in modern manufacturing systems. [1] It carries the goods between the workshop along the designated paths. The ability of localization and recognizing the environment around themselves is the essential technology. AGV navigation is developed from several technologies such as fuzzy theory, neural network and other intelligent technology. Among them, visual navigation is one of the newer navigations, because of its path laying is easy to maintain, can identify variety of road signs. Compared with traditional methods, this approach has a better flexibility and robustness, since it can recognition more than one path branch with high anti-jamming capability. Recognizing the environment from imagery can enhance safety and dependability of an AGV, make it move intelligently and brings broader prospect for it. University West has a Patrolbot which is an AGV robot with basic functions. The task is to enhance the ability of vision analysis, to make it become more practical and flexible. The project is going to add object detection, object recognition and object localization functions on the Patrolbot. This thesis project develops methods based on image recognition, deep learning, machine vision, Convolution Neural Network and related technologies. In this project Patrolbot is a platform to show the result, we can also use this kind of program on any other machines. This report generally describes methods of navigation, image segmentation and object recognition. After analyzing the different methods of image recognition, it is easy to find that Neural Network has more advantages for image recognition, it can reduce the parameters and shorting the training and analyzing time, therefore Convolution Neural Network was introduced detailly. After that, the way to achieve image recognition using convolution neural network was presented and in order to recognize several objects at the same time, an image segmentation was also presented here. On the other hand, to make this image recognition processes to be used widely, the ability of transfer learning becomes important. Therefore, the method of transfer learning is presented to achieve customized requirement.

    Quality assurance of nailed pallet2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis project is about quality assurance of nailed pallet, which is suggesting and evaluating a solution able to detect unknocked nails in a pallet at the company AvenPallen.

    The company AvenPallen is responsible for the production of different kinds of wood products, and these products are usually nailed in a robot cell. Due to variation in the wood, like unevenness of the density and tilt and twist of the boards, the nail may not be completely driven into the wood. This can results in an uneven smoothness of the pallet surface, and the production is unable to meet the requirements of customers and cause waste. To solve this problem the company AvenPallen manages to seek some systems to achieve quality assurance process in nails.

    The project has suggested four possible systems for detecting unknocked nails in a pallet. The suggested systems are mechanical inspection system, optical inspection system, vision technique system and 3D laser scanning system. By consider the situation of the company AvenPallen, there has been two improved system which are: optical inspection system and shadow inspection system. The optical inspection system uses the optical sensor to measure the height of nail to guarantee the quality of pallets. The shadow inspection system uses a CCD camera and a light to get some figures to measure the height of nails to ensure the quality of pallets. The two improved systems have been evaluated through tests. A suggestion of a possible analysis system is also included in the report.

    The report will give the analysis and result for the evaluation experiments and show that the shadow inspection system is a suitable inspection system with the possibility to analyse the measured data.

    Performance evaluation and comparison of Dual-NIC computer Optiplex 780 with Cisco 2901 router2018Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    Evaluation of the dual-NIC computer Dell Optiplex 780 (henceforth referred to as PCR1) compared with Cisco 2901 router regarding performance.

    Both devices are tested to show maximum throughput with increasing numbers of parallel links. A Cisco Catalyst 2960G switch is used to provide more access ports. The software Iperf is used throughout the tests as both traffic generator and throughput measuring tool, meanwhile the software Dstat on PCR1 is used for CPU usage measuring. PCR1 and Cisco 2901 are tested separately. A few basic tests are performed in phase 1 to discover the maximum throughput between the devices' interfaces. In phase 2, additional client computers are added on one side of the router device, one pair at a time. All these clients receive max-load traffic simultaneously from a single server computer, which reside on the other side of the router. Phase 2 tests are meant to investigate how well the router devices handle max-load traffic in a situation where there are multiple clients, whether they prioritize any traffic or function abnormally.

    After both phases are done, an analysis of the collected data is presented, both devices's performance and differences between them will be analysed.

    Western images of China: media representations of Chinese attempts to invest in Saab2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to describe Western images of China by focusing on media representations of Chinese attempts to invest in Saab. Theories of media representation, orientalism, racialization and stereotype are applied and used in the qualitative discourse analysis in order to find out if there are orientalist and racialized stereotypes in the material. The findings show that there are orientalist stereotypes and racialized stereotypes presented in the material. The analysis also sums up that China is a country whose people are represented to be adaptable and to have amazing productivity, since China has cheap labor power and lax labor law. Furthermore, China is represented as a country whose financial power is strong and solid, Western media characterizes China as a threat. Moreover, Chinese negotiators who went to Sweden to negotiate not only are represented as full of ambitions, but also they are seen as the saviors for Western companies which are on the verge of bankrupt. This thesis contributes to the literature by filling the gap about the Chinese attempts to invest in Saab, which is characterized by Western media.

    Factors that affect usage intention towards mobile augmented reality in fashion e-commerce.: A quantitative study using UTAUT2 model2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today e-commerce is growing more and more popular. It might be because of the easy access directly from the home or workplace. It might also have to do with the continuous smartphone evolution allowing more people internet access than ever before. Augmented reality (AR) is a technology that can generate virtual objects and integrate them into the real world. When new technology such as AR enters the field of ecommerce, it is difficult to predict the consumers' response. This study will focus on the factors that are important for consumers' usage intentions towards mobile AR in fashion e-commerce. A few of these factors are how well technology provides benefits in performing certain activities, how easy it is to use technology and how enjoyable it is to use it. Based on past research, an acceptance model (UTAUT2) was adopted to examines what factors affect user's intention to use mobile AR in fashion e-commerce. PLS-SEM was used to estimate the relationship between factors in the UTAUT2 model. With the help of social media, a survey was distributed with the "snowball technique" to gather information. To limit the data, only those between the ages of 16 and 38 were allowed to participate in the survey. Towards the end of the timeframe of collecting data, there were 120 participants. Only two out of the six investigated factors had a positive impact on user's usage intentions: habit and performance expectancy.

    A Lightweight Framework for Tracing andVisualizing Real-Time Operating Systems2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    System tracing is a helpful method for engineersand users to know exactly what happens in an operating system,especially in real-time operating systems (RTOS), because forreal-time system, it is normally more difficult to know theperformance of hardware and software than for desktopcomputers. Although this kind of tracing tools already exist forsome commercial RTOS, it is fairly hard to see those tools forsmall or open source RTOS. Moreover, because the structure andimplementation of different RTOS varies, it is rare to find aframework that can easily be ported to those platforms. In thisthesis, a solution is presented to this general tracing problem ondifferent platforms. By using the portable framework, it ispossible to implement tracing component into a real timeoperating system by some simple reconfigurations. This platformportability feature is accomplished by separating the specificplatform logic from the logic of the tracing part. Finally, adeployment of this framwork onto a small open source real-timeoperating system—AtomThreads, running on an AVRATmega1650 – is used as a demonstration of this framework.

    Safe Human Robot Collaboration: By using laser scanners, robot safety monitoring system and trap routine speed control2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Nowadays, robot is commonly used to perform automation tasks. With the trend of low volume and customised products, flexible manufacturing is introduced to increase working efficiency and flexibility. Therefore, human robot collaboration plays an important role in automation production and safety should be considered in the design of this kind of robot cell. This work presents the design of safe human robot collaboration by equipping an industrial robot cell with SICK laser scanners, safety monitoring system and trap routine speed control. It also investigates the reliability of RGB-D camera for robot safety. This work aims to find a safety robot system using standard industrial robot for human robot collaboration. The challenge is to ensure the operator's safety at all times. It investigates safety standards and directives, safety requirements of collaboration, and related works for the design of collaborative robot cell, and makes risk assessment before carrying out the valuation. Based on literature review, it gives the concept of layout design and logic for slow down and resume of robot motion. The speed will be first reduced to manual speed and then zero speed depending on the distance between the human and the robot. Valuation and verification are made in the proposed safe solution for human robot collaboration to test the reliability and feasibility. This project realizes the automatic resume that the robot can con-tinue working without manually pressing reset button after the operator leaves the robot cell if there is no access to the prohibited area. In addition, it also adopts the manual reset at the same time to ensure the safety when people access the prohibited area. Several special cases that may happen in the human robot collaboration are described and analysed. Furthermore, the future work is presented to make improvements for the proposed safety robot cell design.

    Identifying the key source of deteriorating educational equity in Sweden between 1998 and 20142019In: International Journal of Educational Research, ISSN 0883-0355, E-ISSN 1873-538X, Vol. 93, p. 79-90Article in journal (Refereed)
    Abstract [en]

    Educational equity has deteriorated in Sweden from the late 1980s onwards. However, it is not clear what the main sources behind this trend are. The present study aims therefore to investigate the development of educational equity at different levels of the Swedish educational system inorder to identify possible sources of the change. Students' school grades and family educational background for the cohorts leaving compulsory school between 1998 and 2014 were analysed in three-level hierarchical models. Increased segregation with respect to student composition and academic outcomes across different schools was found to be the main source of the declining educational equity. The findings are discussed in the light of differentiated learning opportunities, as a result of recent school reforms in Sweden.

    Work-life balance och verkstadschefer2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Previous research suggests that to have a good relationship between work and private life it is important to experience a-good mental health and success at work. The industrial managers’ in this study were undergoing a major change at their workplace and this study found examined how five male managers’ perception of their work-life balance. One of the aims of this study was to examine how the managers’ roles at home affects work-life balance (WLB), to what degree support at home affects WLB, and the impact that a balance or a conflict could have. The study was conducted qualitatively with a semi-structured interview guide and every manager was affected by the change at the workplace. The results showed that some of the managers were experiencing work-life conflicts where others were on the other hand experiencing a good WLB. The most common reason for feeling conflict between work-life was the uneven amount of workload, which occurred to a greater extent due to the change. These periods of uneven workload caused the managers to feel less control. One of the things that caused the managers to feel frustration is that they had limited resources and authority to handle the demands at work. The situation at home also had a very big impact on whether the managers’ experienced a good WLB or not.

    The Conversation between Film and Ideology: How Wall Street and Wall Street. Money Never Sleeps promote and/or criticize financial capitalism? 2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is, within two films Wall Street and Wall Street. Money Never Sleeps, to explore characters from different levels of capitalism’s characteristics and ideological positions, what kind of society and ideological patterns the two films reflect and in which ways do the films promote and/or criticize capitalism. Theories on ideology and ideology critique are applied and used in a discourse analysis in order to compare characters of different levels of capitalism’s ideologies and characteristics over times in the films and describe what kind of society and ideological patterns the two films reflect. The outcomes show that characters’ ideologies and characteristics actually change over times in the films. And the outcomes also show that the two films generally promote capitalism by creating same model of story under different societies and ideological patterns.

    Balancing WAAM Production Costs and Wall Surface Quality through Parameter Selection: A Case Study of an Al-Mg5 Alloy Multilayer-Non-Oscillated Single Pass Wall2019In: Journal of Manufacturing and Materials Processing, E-ISSN 2504-4494, Vol. 3, no 2, p. 1-19Article in journal (Refereed)
    Abstract [en]

    The purpose of the study was to propose a strategy to assess the potential reduction of the production cost during wire+arc additive manufacturing (WAAM) based on the combination of wire feed speed (related to deposition rate) and travel speed (related to deposition time). A series of experiments, using a multilayer-non-oscillated single pass wall made of an Al-Mg alloy, was conducted. The quality of the wall was assessed through the lateral surface waviness and top layer undulation. The concepts of Surface Waviness and Buy-to-Apply indices were introduced. Initially, the range of travel speed (TS) that provided layers with acceptable quality was determined for a given wire feed speed (WFS), corresponding to a constant current. Then, the effect of the increase of production capacity of the process (though current raising, yet maintaining the ratio WFS/TS constant) on the wall quality for a given condition within the TS range was assessed. The results showed that the useful range of TS prevents too rough a waving surface below the lower limit and top surface undulation over the higher limit. However, inside the range, there is little quality variation for the case under study. Finally, simulations of deposition time were developed to demonstrate the weight of the TS on the final deposition time and wall quality as a function of a target wall width. This respective weight showed the existence of a complex and unpredictable, yet determined, power of a combination of TS, target wall geometry, and dead time between subsequent layers. It was verified to be possible to find optimized TS as a function of different target geometries.

    Sambandet mellan den ekonomiska tillväxten och arbetsmarknaden2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The relationship between GDP-growth and Unemployment as a two-variable equation was established by Arthur Okun in the 1960´s. The equation was later called Okun´s law because it provided a fitting description of the relation between GDP-growth and unemployment. Studies in the late 2000´s has shown that the relationship is diminishing as the markets for GDP-growth and Unemployment becomes more complex.

    This studies purpose is to examine the relation between GDP-growth and unemployment, and which form of GDP that explains unemployment levels the best. The authors of this paper will use three models, the difference version, the levels version and the gap version that each describes the relationship between various forms of GDP and unemployment. The countries the relationship will be tested for is Sweden and the U.S for the time period 2001-2018 by using quarterly data for the countries and see if the relationship differs between the countries and the plausible explanations on why it differs.

    Results from the studies show that the relationship is best described by the levels version and that the countries in this paper don´t differ a lot from each other and the studies that was conducted by Okun in the 1960´s.

    Fueling the Dragon’s Power: China’s oil trade through a lens of International politics2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study is focus on China’s activities/policies in oil trade and security for keeping its own development. In this study, we try to analyze China’s activities and policies in oil trading through liberalism and realism, and to show out how China acted in global market related to oil consumption, production and trade in order to satisfy China’s oil requirements. In international political theories, the concept of realism and liberalism are almost completely opposite. The cases of activities and relevant data which we selected with China on oil trade are picked and analyzed by historical analysis and quantitative researches. That can ensure the credibility, applicability and correctness of data. After analysis, the findings show that Chinese central government guide by realism more than liberalism when it process the issues with oil trade. China considers from the perspective of their own interests and focus on how to maximize their own interest. From the surface, the partners of China also received interests, but the main target of China is ensure the security of the oil, and maintain the stability of the domestic energy consumption.

    Tourism – Fair enough?: Evaluating empowerment and the implementation of FTTSA principles in hotels, in Cape Town2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Bachelor's thesis tries to find out the most significant differences between Fair Trade Tourism (FTT) -hotels and conventional hotels in Cape Town, through a descriptive comparative study, done with semi-structured interviews. More in detail, the study finds out do the principles of Fair Trade Tourism in South Africa (FTTSA), implemented by the FTT hotels, provide the wanted outcomes, and how do these outcomes empower the staff working in the hotels. The same perspective is used on the conventional hotels in terms of the principles, to see the significance of difference. This research uses a qualitative method, and applies the theories of policy implementation and empowerment to analyze the results. The analysis is done as a content analysis based on the results gained from the interviews. The content analysis discloses, that even though the FTT hotels did not completely follow all the principles of FTTSA, nor produced the exact wanted outcomes, they offered the best well-being for the employees. The well-being again, on many levels, was able to cause empowerment for the staff. In addition, what is revealed from the analysis is that the information and knowledge were often unbalanced between the management and the employees. Due to this, it could be concluded that the flow of communication is asymmetric at the hotels. For FTTSA -principles and FTT labels to be more politically relevant and significant, they should be implemented on a larger scale.

    Abstract [en]

    Detail development plans are a way for the municipalities to regulate the use of land and water territories. The map that follows with the detail development plan is a legal document used by the municipalities to shape the area of the plan by using plan regulations. With the map follows a plan description which describes the purpose of plan, presents the implementation of the plan and the consequences it has on interested parties, the environment and other parties that could be affected by the detail development plan.

    In the case of deficient plan regulations och plan description the consequences for the afflicted parties can lead to costly and drawn out processes. Earlier studies showed that 17 % of all approved detail development plans contained deficient plan regulations.

    According to earlier regulations, the municipalities did not have to consult with the cadastrial authorities for every planning proposal. During this time, the role of the cadastral authority was to make sure the plan regulations refering to property law were correct in their configuration not to cause negative consequenses to the implementation of the detail development plan. The role of the cadastral authories changed in conjunction with a constitutional amendment to the law which took effect 1 januari 2015. The government wanted to make the planning implementation more effective and one way to achieve this was to give the cadastral authority a more distinct and extended role during the planning process.

    The purpose of this study is to examine how the municipalities respond to comments made by the cadastral authority during the review time. The result shows that after the first review time 12 % of the detail development plans that the cadastral authority made remarks on had not been corrected by the municipalities. After the second review time, the procentage had decreased to 7 % of all detail development plans. When comparing the actions taken by municipalities with communal cadastral authority and municipalities with state cadastral authority the analysis showed that there where no significant differences between them.

    The studie indicates that the municipalities listen to the opinions and advice given by the cadastral authority, thereby deficient plan regulations and plan descriptions are amended accordingly. This will hopefully lead to a more effective implementation of the detail development plans.

    3D Scanning and Modeling with the use of a Mobile Robot2017Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years, the number of mobile robot has increased rapidly. They can not only be used for carrying out tasks in hostile work environment, but also make people's daily life convenient. In the meantime, the rise of 3D technology has changed people's life with its applications in the fields of industrial life and daily life. Therefore, the combination of 3D technology and mobile robot has enormous potentials.

    The objective of this project is to create a model of an object or indoor environment with the help of a mobile robot. A 3D scanner which can be attached on a mobile robot will be used for scanning. With the depth information collected, the point clouds can be gotten. The basic way of reconstructing the model is called Kinect Fusion, it uses Kinect camera to scan the area and creates a model with help of Iterative Closest Point algorithm and Truncated signed distance function which will be introduced in section 2.5. The registration of the point clouds and the localization of the camera can be realized by using ICP algorithm. The software which is used to implement these methods is Visual Studio 2012 with OpenCV and KinectFusion library.

    As the camera should be able to be used on any kind of robot, the aim of these tests is to find a better way to get a high quality model of the area. In this paper, two main experiments have been done. One of them is about scanning a target object from different distances. There will be errors between object actual size and its model size. And the relationship between the errors and the distances will be found out. The other one is focused on the movement of the camera. There are two scenarios in this experiment. The first one is to move the camera with different speed and the other scenario is to scan an object by moving the camera around the object. The result shows that the robot attached with the camera should move slowly so that the camera can capture enough frame images for the model. And keep scanning one object by moving the camera around it can't make the model looks better but worse.

    Stereotypes of Chinese Athletes: Critical Discourse Analysis of Western Sports Journalism2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to collect and analyze stereotypes of Chinese athletes in Western sports journalism. The thesis employs a single case study of the construction of Chinese athletes in Western media. This study is based on the assumption of Social constructivism and it is combined with media representation theory. Furthermore, racial stereotypes and Orientalism theory are applied to collect and explain the stereotypes of Chinese athletes in Western media. The finding shows that Chinese athletes as a threat to West are constructed not only in the competition of the Olympics, but also in other social aspects such as institution, economy and population. Moreover, through critical discourse analysis (CDA), the analysis proves that racial stereotypes (physical and mental) of Chinese athletes have been represented in Western sports journalism. Additionally, the analysis of power relations which is drawn from Orientalism contributes to the understanding of the presence of these stereotypes. This research contributes to the existing literature by filling the gap in research on racial stereotypes of Chinese athletes in Western sports journalism.

    Effektivare bagagehantering vid Mogadishu´s flygplats2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this thesis, the main objective was to access improvement suggestions that will allow the SKA International Group to produce smoothed throughput at Mogadishu's airport. SKA International Group is a logistics company which took over responsibility at the airport three years ago. The company’s mission was to build the airport, and make it one of the best in the region. After three years, air traffic at the airport has increased significantly, which meant that the baggage handling became a major problem. The company has not applied for a newer and more modern equipment to cope with the pressure of the baggage that increases in number with each passing day. The work consisted of a theoretical part with a literature study based on contemporary research and also a qualitative study by interviewing a number of people at the company. There is also a survey of the company's process flow using a tool called value stream mapping. With the help of the analysis, it identified what is value-adding and non-value adding time for baggage handling. The analysis identified also areas for improvement that were critical in order to reduce the lead time. At the end of this project, it mentions a number of suggestions for improvement that can create the conditions for a successful change for the better. One of the main improvement suggestions there is how the company can achieve lead time reduction at the airport

    Sjöobodsupplåtelser: kartläggning och reflektioner2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I uppdrag av Kungälvs kommun har en kartläggning gjorts mellan olika kommuner inom Bohuslän samt Göteborg som senare ska fungera som planeringsunderlag för kommunen. Kartläggningen bygger på ett frågeformulär som har skickats till kommunerna Göteborg, Tanum, Öckerö, Tjörn, Orust, Strömstad, Lysekil, Sotenäs och Kungälv. Innan frågeformuläret skickades in gjordes en omfattande litteraturstudie om kommunernas hantering av sjöbodar.

    Utgångspunkten med kartläggningen har varit att ta reda på hur kommunerna hanterar sina sjöbodar, med avseende på exempelvis deras upplåtelseformer, upplåtelsetider, avgifter, avtalsvillkor, användning och styrning med hjälp av detaljplan, bygglov och tillsyn, kommunens egna reflektioner på hur deras hantering fungerar m.m.

    Teoridelen består av allmän information om:

    - Sjöbodar, definitioner och användning.

    - Arrende, då den är en utav de vanligaste upplåtelseformerna för sjöbodar, med avseende på anläggningsarrende och lägenhetsarrende.

    - Hyra, är en annan form av upplåtelse som används i ett par kommuner.

    - Hur det kan fungera när kommunen äger marken som ska arrenderas

    - En gemensam sjöbodspolicy som tillämpas i ett fåtal kommuner.

    Resultatet är en sammanställning av den information som har tagits reda på genom frågeformulärens svar. Svaren från frågeformulären informerade bland annat om att det finns mellan 25 stycken till 1200 stycken sjöbodar i kommunerna och att upplåtelse av sjöbodar sker vanligtvis genom arrende men också till viss del genom hyra. Upplåtelsetiden brukar vara på ett år med automatiskt förlängning. Avgifterna ligger på mellan 887 kr upp till 2800 kr. De flesta kommunerna försöker också styra sjöbodarnas utformning och användning genom avtalsvillkor, regler och bygglov.

    Den generella uppfattningen som kartläggningen resulterar i är att de flesta kommunerna vill uppdatera sina sjöbodshanteringar. Resultatet tydliggör att det finns likheter och skillnader i tillämpningen av sjöbodsupplåtelser mellan kommunerna. Vissa kommuner har exempelvis inga fördelningsregler för vem som ska ha rätt till en sjöbod i kommunen. I dessa fall får arrendatorn själv hitta en lämplig köpare av boden och detta leder till minskad tillsyn och kontroll från kommunen över vem som tillträder arrendet.

    Det finns inte så många kommuner som använder en detaljplan för att styra användning och utformning av en sjöbod, vilket skulle kunna styras bättre om kommunerna ökade användningen av detaljplaner för sjöbodar.

    EXAMENSARBETE

    Efter genomförd kartläggning blir slutsatsen att en kommun kan ha en bra hantering av sjöbodar om det finns en sjöbodspolicy som upplyser om vad en sjöbod är och hur den ska användas, tillämpningsregler från kommunerna som kan vara lättillgängligt för allmänheten, ett arrendeavtal som har sjöbodspolicyn och tillämpningsreglerna som komplement och en detaljplan med planbestämmelser för hur sjöbodarna och marken kring sjöbodarna ska hanteras.

    Prissättning på bostadsrätter i Göteborg: Vilka egenskaper är det som påverkar priserna och hur mycket påverkar dem?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to find out which characteristics that's affecting the prices of condominiums in Gothenburg and by how much each of them affect. It is widely known that there are many factors that can increase the price of a condominium, the question is to what extent? By using the hedonic pricing model and multiple regression analyzes, we have been able to estimate how much each of these factors affect the price. The study is a cross-sectional study comprising 100 observations in Gothenburg city (downtown, east, west and Hisningen) collected from two different brokerage firms in Gothenburg during 2013-2014. These observations have been divided into a total of 23 variables, which includes living area , number of rooms (RoK) , fee, area/location , year of construction , balcony and elevator which are independent variables aimed at explaining the dependent variable, residential price. The results showed that 11 of the 23 variables showed statistical significance which includes living area, fee, and several of the location variables showed the expected results. Features such as number of rooms, elevator, balcony and floor is something that is constantly in demand by speculators but showed insignificance in the study, which means that, according to this study, that they do not have an impact on the final price. This may be due to multicollinearity and the shortage of observations. As the study is the first of its kind for condominium market in Gothenburg, we believe that there is now a good foundation that simply and clearly shows the significant property influences on housing price

    En studie om hur Reko har påverkat branschen för redovisningskonsulter: en undersökning kring den institutionella effekten Reko har fått2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The audit requirement was abolished in Sweden on the first of november 2010. As a result of the abolition approximately 70 percent of Swedish companies choosed voluntary audit. With this, accountants have become more important and the auditors would now have to compete with the accountants in order to offer the accounting services that would be demanded. As the responsibility and involvement of the accountants increased in the industry, Reko was introduced. Reko is a framework aim at authorized accountants and is developed by professional organizations such as SRF and FAR in order to provide a high quality of accounting services. The question we ask in our study is "do accountants work in accordance with Reko". The purpose of this study is to determine by Reko the institutional impact of the framework on accountants that are not authorized and aslo those who do not havet o follow Reko. We have chosen to work according to a qualitative method in order to achieve our purpose. We have interviewed four authorized accountants and four accountants who are not authorized. These interviewes have been conducted on respondents who work at different agencies, from small to medium ones. Theories that have been used in the essay are institutional theory, that explains people´s adaptation to groups and organizations as well as isomorphism that describes why groups tend to resemble each other and what contributes to the similarities. Our empirical evidence suggests that accountants find that they work in accordance with Reko and that it is not only authorized accountants who work according to Reko. Our empirical evidence also indicates that the industry has a homogeneous mindset about Reko and that the framework is associated with legitimacy and acceptance in the industry. The result suggests that accountants find that they work in accordance with Reko and that they seem to be isomorph in the industry. Based on this finding, it is concluded that Reko has had an institutional impact on accountants who are not authorized because they are those who do not havet o follow Reko.

    Role of inclusions in formation of high strength steel weld metal microstructures2013In: Science and technology of welding and joining, ISSN 1362-1718, E-ISSN 1743-2936, Vol. 18, no 7, p. 603-609Article in journal (Refereed)
    Abstract [en]

    A series of high strength weld metals with varying Al content are studied. The inclusions are characterised using energy dispersive X-ray analysis and electron diffraction. The tendency for alignment of the microstructure is characterised quantitatively using electron backscatter diffraction and a recently developed post-processing technique. Correlation is found between the inclusion phases present and the amount of aligned neighbouring grains in the microstructure. It is shown that amorphous Si-Al oxides form at low Al weld metal contents and an Mg-Al spinel at higher contents. The former is associated with less alignment of the microstructure and therefore higher impact toughness. The effect of these inclusions on the formation of the microstructure is discussed.

    A new EBSD based methodology for the quantitative characterisation of microstructures formed by displacive fcc–bcc transformations2013In: Micron, ISSN 0968-4328, E-ISSN 1878-4291, Vol. 45, no February, p. 45-54Article in journal (Refereed)
    Abstract [en]

    This work is concerned with a new methodology that can be used to quantify the degree to which grains in the microstructure are aligned in the form of packets. The methodology is based on a crystallographic definition of the term packet which is used to deduce the theoretically ideal misorientations of intra-packet grain boundaries. A misorientation distribution obtained from extensive EBSD mapping can thus be split into intra- and inter-packet misorientations and the corresponding fractions can be determined by integration. The theoretical framework of the methodology is explained and a step-by-step description of the procedure is given. Results from a trace analysis are provided to justify the assumptions made regarding habit plane and examples are included showing how the grain boundary network can be split into two separate parts, one for lath boundaries and the other for packet boundaries. Moreover, example weld metal microstructures along with the corresponding misorientation distributions as well as quantitative values of the microstructures are presented.

    Empowerment: A word of coherence?: a comparative study about the representations of empowerment by South Africa's B-BBEE act, Fairtrade South Africa, and the target group of black empowerment within the implementation process2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Bachelor's thesis is conducted with semi-structured interviews and texts and is analyzing how the concept empowerment is represented in South Africa. More specifically, this case study investigates, (1) how do the national South-African policy of empowerment, Fairtrade South Africa, and the target group describe what the goal of empowerment is? (2) How do the national South-African policy of empowerment, Fairtrade South Africa, and the target group describe the problem, causes and solutions in relation to empowerment? (3) What are the similarities and differences of the actors' representations of empowerment, and what implications may potential conflicts have for the prospect to successfully achieve the national goal of black empowerment? This research has a qualitative approach and uses implementation theory in relation to representation. The content analysis of our data illustrates that the representations of empowerment made by the different actors in the implementation process have many differences and yet not many similarities. The analysis illustrates that three main conflicts are evident when comparing the different actors' representations of empowerment. These are related to critical thinking, the conflicting individual and collective perspectives, and if the problem of disempowerment is caused by past or present structures. These conflicts in the three actors' representations of empowerment can cause bias and delay or possible failure in the policy implementation of black empowerment, yet all actors agreed on the goal of empowerment to be self-determination.

    Upplevelserna av det första året som yrkesverksam sjuksköterska: En litteraturbaserad studie2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Registered nurses is a profession with long tradition and the profession has undergone many changes over time. In Sweden, today, nursing education leads to an academic degree but also provides a vocational degree. Profession as a nurse requires much of the practitioner for this to be considered competent to maintain credentials. The path from novice to expert is long while the lack of nurses is large and many choose to leave the profession. Aim: The aim was to describe how newly graduated nurses’ experience their first year as professional nurses. Method: A literature-based study was conducted in which ten qualitative studies were retrieved from the databases Cinahl, Proquest and Pubmed. The studies were subjected to quality assurance and Friberg's five-step analysis.  Result: Through the analysis, the results of the articles were compiled into a new result, in which three themes, and nine subthemes were formed. The main themes were “unreasonable expectations about the new profession”, “the first year - a reality shock” and “the need for support in the workplace”. Conclusion: The first year of occupational nurses was experienced a difficult period and was lined with feelings of unpreparedness for what the profession meant and expectations of the profession that did not really correspond. The need for support was considered important for transition from education to professional nurse to be successful. The workplace of the graduates graduated was crucial for whether the nurse came to stay in the profession or not.

    Abstract [en]

    Background: Breast cancer is the most common form of cancer in women. It is considered anappalling disease with its high mortality, demanding treatment and major impact on selfimageand body perception.

    Aim: The aim of this study is to describe women's experiences of being diagnosed and treatedfor breast cancer and how the breast cancer affects their life situation.

    Method: The method used was a literature study based on qualitative research. Eleven studieswere analysed according to the five-step model by Friberg.

    Results: The analysis resulted in three main themes and sex subthemes. The main themeswere: The life is threatened, Suffer from disease and Life continues.

    Conclusion: Suffering from breast cancer imposes changes on all aspects of the women's life,both physically, mentally and socially and evokes various individual coping strategies. In thisprocess it is vital that the nurse, which is closest to the patient, has a good understanding ofthe various patterns of crisis reaction to be able to deliver a good professional care andindividual support to the women.

    Sponsring på lokal nivå: Företags syften med idrottssponsring2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sponsorship has long been involved and supported the sport in Sweden, and has over the years developed from pure donations to be more professional. Today turnover of sport sponsorship in Sweden 6.5 billion crowns. Unions, both large and small, are more or less dependent on revenues from the sponsoring company. In some sports, this income is absolutely critical that the association continued to operate its business. A useful tool in the sponsorship is the ERK model, a model designed to provide an overview of the concept of sponsorship and what effects it may cause. The purpose of the study is to analyze the motives behind the company's decision to sponsor the local sport, and if the ERK model can be applied at this level. The study is based on a qualitative approach with a hermeneutic view. Data collections have been performed by personal semi structure interviews with respondents from different companies with positions which imply a sponsorship responsibility. In the study have data been collected by using help of four participating companies. In our theoretical rame of reference we present our approach in the literature collection, with motivation for the selected theory and problems in literature collection. Furthermore, it defines the concept of sponsorship, followed by theories on the spon-sorship purposes in sport and the smaller companies perspective. The theoretical rame of refer-ence ends with the study's interpretation model. Study results show that companies purposes with their sponsorship in some parts differ, while even some common patterns can be seen. It shows that the motives for sponsorship in earlier research raises, even to some extent, can be applied to the study's participating companies. The ERK model appears to miss some parts to be a complete tool. Finally we can determine that the motive for sponsorship varies from com-pany to company. By taking this into consideration in sponsorship work both the companies and the associations can get more in exchange of each other. The study's main contribution is to give an overview on which motives companies in Trollhättan and Vänersborg have with their local sports sponsorship. An interesting suggestion for future research is to continue to investi-gate the sports sponsorship at the local level, in the way of union's perspective

    Konstruktion och formgivning av diagnos- och testverktyg2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Dagens biltillverkare tillverkar allt mer avancerade och komplexa elektroniska system i sina fordon. Det finns mellan 40 och 70 elektroniska styrenheter i en bil. Styrenheterna kontrollerar och reglerar allt från komplicerade bränslesystem till sätesuppvärmning. För att hitta elektroniska fel snabbt och säkert är funktionell och enkel diagnos- och testutrustning en bra investering för verkstäderna. Cabeco AB tillverkar och utvecklar diagnos- och testutrustningar. Genom att förnya designen och användarvänligheten och genom undersökning av mer miljövänliga material, utvecklades ett diagnosverktyg, Break-Out-Box. Med hjälp av etablerade produktutvecklingsmetoder togs fyra olika koncept fram. Två koncept valdes ut för fortsatt utveckling och endast ett av koncepten utvecklades fullständigt. En prototyp av den tillverkades. Resultatet av det nya konceptet visar att materialåtgången har minskats, monteringstiden blir betydligt kortare, verktygskostnaderna blir lägre, antalet monteringsoperationer blir färre, vilket sammantaget ger betydligt lägre tillverkningskostnader. Det har också lett till att de viktigaste kundkraven blev uppfyllda.

    Abstract [en]

    The aim of this study is to explore how sports journalism can include and/or exclude athletics from a national community. This study put emphasis on finding patterns from articles by Swedish sport media on non-ethnic Swedish athletics. The theories central to this study are ethnicity and nationalism, as these concepts contain reflections on why certain groups of people are excluded and/or included. Norman Faircloghs critical discourse analytical model has been selected for the study method that analyzes texts in three levels: the text level, discursive practice and social practice. Four non-ethnic Swedish athletes have been chosen to explore how they were portrayed in the media. Data were collected from Swedish newspapers, sport websites and blogs that portrayed the selected athletes. Discourses of media, nationalism and ethnicity emerged through a critical analysis of the data collection. The results of the study show that the selected athletes are included in to the Swedish national community through their achievements in their respective sport.

    How does Amnesty International portray victims of sexual violence during armed conflicts?: - The role of gender in the construction of victimhood2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The following Bachelor’s thesis is a descriptive single case study on how Amnesty International portrays victims of CRSV. More specifically, it examines how victim portrayal is connected to the conceptualizations of masculinity and femininity through applying a social constructionist gender perspective combined with the ideal victim theory. The analysis has been conducted through a careful examination of Amnesty reports treating the issue of sexual victimization within the context of conflicts collected from Amnesty International’s webpage. The research findings indicate that Amnesty International relies on a gendered understanding concerning who can be an ideal victim of sexualized violence. It mainly portrays victims in the light of female gender, i.e., with feminine assumptions, relying on the essentialist perception of vulnerable/weak women and dominant/aggressive men. While efforts by Amnesty to acknowledge male victimization has not happened in isolation, the acknowledgment has however been only limited to recognition rather than a detailed consideration of the issue.

    Kulturella värden, tro, levnadssätt och livsstil: faktorer som påverkar sjuksköterskans möte med muslimska patienter2006Independent thesis Advanced level (professional degree)Student thesis
    Abstract [sv]

    There are over 1,5 billion Muslims living on earth and the religion is one of the world´s most increasing. Sweden is a country with a cultural diversity where about 300 000 Muslims lived in 1999. Today, the requirement for knowledge about caring for Muslims and the need of culturally competent nursing care are increasing.The aim of this study was to define cultural factors which the nurse has to recognize to be able to give culturally competent care to the Muslim patient. The method that has been used was a The Sunrise Model, which illustrates Leininger´s theory of culture care diversity and universality, provides a theoretical framework for the study. The results are presented on the basis of Leininger´s three cultural factors; cultural values, beliefs and lifeways. Factors that where especially important to recognize for the nurse were the perception of health and illness, prayer, death, gender roles, family, clothing, diet and communication.

    Evidence of mantle upwelling/downwelling and localized subduction on Venus from the body-force vector analysis2018In: Planetary and Space Science, ISSN 0032-0633, E-ISSN 1873-5088, Vol. 157, p. 48-62Article in journal (Refereed)
    Abstract [en]

    Considering that Venus has a size very similar to Earth, thermal evolution of both planets should be comparable. Nonetheless, there is no clear evidence of plate tectonics or plate motions on Venus. Instead, various surface deformations attributed to volcanism, resurfacing, localized subduction and other geologic processes were recognized on the planet. In this study we attempt to classify the origin of lithospheric forces on Venus based on using topographic and gravity information. For this purpose, we also estimate the Venusian crustal thickness. In agreement with findings from previous studies, the signature of past or recent global tectonism in the body-force vector pattern on Venus is absent, while exhibiting only regional anomalies. The maximum intensity inferred in the Atla and Beta Regios is likely attributed to mantle upwelling. This is also confirmed by the gravity-topography spectral correlation and admittance analysis that shows the isostatic relaxation of these volcanic regions. The regional body-force pattern in the Bell Regio suggests that a much less pronounced force intensity there is possibly related to crustal load of lava flows. Elsewhere, the body-force intensity is relatively weak, with slightly more pronounced intensity around the Ishtar Terra and the Arthemis Chasmata. The body-force pattern in the Arthemis Chasmata supports the hypothesis that coronae structures are the result of mantle upwelling and the subsequent (localized) plume-induced subduction with only limited horizontal crustal motions. The prevailing divergent pattern of body-force vectors in the Ishtar Terra region suggests the presence of tensional forces due to the downwelling mantle flow that is responsible for a crustal thickening along the Freyja and Maxwell Montes. Except for the Atla and Beta Regios where the isostasy is relaxed by the (active) mantle plumes, the crustal thickness is spatially highly correlated with the topography, with a thin crust under the plains and a thick crust under the plateaus. The maximum Moho depth under the Maxwell Montes in the Ishtar Terra exceeds 90 km.

    Perceived resource scarcity and environmental behaviors – how do they relate?2017Conference paper (Other academic)
    Abstract [en]

    Sustainability challenges largely have to do with valuing past, present and future resources. History is full of examples of humans and societies that threat, react to changes in, and preserve resources they depend on. However, there is surprisingly little research on attitudal or behavioral reactions to decreasing or increasing resource levels in the fieldof environmental studies. This study aims to investigate the impact of individual experience-based subjective evaluations of different types of resources on environmental attitudes and behavior. The study is explorative since the relation between subjective resources and environmental attitudes and behavior to our knowledge has never been investigated. There are good reasons to expect both negative and positive correlations between perceived scarcity of resources and environmental behavior (partly depending on what resource we have in mind). The theoretical model is based on an understanding of environmental behavior as a collective action problem based in a social dilemma. The link between perceived scarcity of resources and environmental attitudes and behavior is investigated in a survey to the Swedish public (N = 978), which also controls for people's social value orientation (SVO), subjective well-being, and generalized trust and trust in environmental institutions, as well as income, age and gender.

    Högläsning i förskolan: med fokus på pedagogens förhållningssätt2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det är en kvalitativ studie som syftar till att ta reda på pedagogens intentioner med högläsning och bidra med en djupare insyn i förskolors läsvanor samt pedagogens förhållningssätt under högläsningsstunder. Vi blev inspirerade för ämnet under vår verksamhetsförlagda utbildning. Vår upplevelse är att högläsning är en viktig del i förskolans verksamhet som barnen möter dagligen. Samtidigt uppmärksammade vi att pedagoger som använder sig av högläsning tenderar att ha olika syften med aktiviteten. Mot bakgrund av denna förståelse har vi bestämt oss för att studera forskning i form av artiklar, avhandlingar, rapporter och litteratur. De presenterade författarna i den tidigare forskningen redogör att högläsning kan vara en språkutvecklande aktivitet som gynnar barnens förståelseförmåga, kommunikationsförmåga och literacyförmågor i form av läs och skriv kompetenser. Den tidigare forskningen visar även att pedagogen och pedagogens förhållningssätt har en avgörande roll under högläsningsstunder. I studien utgår vi från sociokulturella aspekter. De centrala begreppen som vi har valt att fördjupa oss i är språk och kommunikation, den proximala utvecklingszonen och interaktion. Inom det sociokulturella perspektivet sker barnens lärande och utveckling genom samspel, interaktion och med hjälp av den mer kompetenta. I detta har språk och kommunikation en central roll. Metoden som används för att besvara studiens forskningsfrågor är kvalitativa semistrukturerade intervjuer, i vilka nio informanter deltar. Studiens resultat har visat att högläsning är en rutinmässig aktivitet som sker i samband med samling, fruktstund samt innan och efter lunch i förskolan. Pedagogerna var alla överens om att högläsningen är betydelsefull för barnen. Högläsning framställdes som en aktivitet som främjar barnens språk, uttal, ordförråd, literacyförmågor, den fonologiska utvecklingen och den kognitiva förmågan. Trots det visar resultatet att pedagogerna har olika syften med högläsningen. Fyra av nio informanter belyser att de använder högläsning i språkutvecklande syfte. De resterande beskriver däremot att de använder högläsning främst i lugnande syfte. Vidare har det framkommit att urvalet av litteraturen som ska läsas går till på olika sätt. Endast två pedagoger betonar att urvalet av litteraturen sker av barn utefter deras intressen. De resterande pedagogerna har däremot belyst att de väljer ut litteraturen som de anser är tilltalande på ett personligt sätt.

    Främlingsfientlighet i skolan: en kvalitativ intervjustudie om hur rektorer hanterar främlingsfientliga idéer2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Främlingsfientlighet är ett ständigt debatterat ämne i media där det påstås att främlingsfientligheten hos barn och ungdomar ökar. Skolan har blivit en arena där främlingsfientliga organisationer kan rekrytera medlemmar. Vi är intresserade av att ta reda på hur rektorer hanterar detta. Den svenska yttrandefrihetsgrundlagen kan hamna i kollision med de demokratiska värderingar skolan skall arbeta med. Detta är ett intressant problem som behöver forskas i. I Ytterby vägrades en elev godkänt betyg i samhällskunskap då han vägrat arbeta med en elev av utländsk härkomst. Främlingsfientligheten sprider ut sig i de svenska skolorna och många elever kränks på grund av sitt ursprung.

    Syfte: Syftet med vår studie är att undersöka hur rektorer hanterar främlingsfientliga idéer och yttringar i skolan.

    Metod: Vi har valt att använda oss av en kvalitativ metod för att få så detaljerade intervjuer och resultat som möjligt. Vi har intervjuat åtta rektorer i fyra olika kommuner.

    Resultat: Rektorerna är överens om att främlingsfientlighet handlar om kränkningar. De säger att det inte förekommer främlingsfientliga kränkningar i större utsträckning på deras skolor, men att främlingsfientligt klotter uppmärksammats på skolor med högre antal invandrare. Det är ovanligt att elever bär främlingsfientliga kläder eller symboler. Främlingsfientliga organisationer som försöker ta kontakt med elever eller personal på skolan är också ovanligt. Gränsen för vad man får säga och göra i skolan går vid när en person känner sig kränkt, detta är samtliga skolledare överens om.

    Rektorerna anser att främlingsfientlighet yttrar sig på en mängd olika sätt. Alla rektorerna tror att hemmet kan vara en källa där främlingsfientligheten gror. De tror även att kompisar, organisationer och media kan påverka. Skolledarna har svårt att bestämma vem som är det största problemet, elever med främlingsfientliga åsikter eller främlingsfientliga organisationer. De tror att det är en blandning av dessa. På de skolorna som har mycket invandrare tror rektorerna att främlingsfientligheten har ökat medan rektorerna på skolor med lite invandrare tror att det inte har ökat. Rektorerna tycker att man ska framhålla värdegrundsarbetet för att motverka främlingsfientlighet. De anser att man ska reda ut främlingsfientliga problem på individnivå. Skolledarna är helt överens om att yttrandefrihetslagen väger tyngre än skolans demokratiska värderingar. Samtliga skolor har en likabehandlingsplan som används men orden främlingsfientlighet eller rasism omnämns inte. Rektorerna tycker att de är väl insatta i de styrdokument som finns.

    Gemenskapens betydelse för personer som är på väg ur ett långvarigt drogmissbruk: En kvalitativ studie kring deltagarnas egna perspektiv på gemenskap2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to gain a deeper understanding of the individual's own experiences on the way out of the abuse. The study was conducted with a hermeneutic / phenomenological approach in which qualitative interviews were conducted with five people including 2 women and 3 men. The selection criteria were that they'd had a long been abuse, and taken out of it for at least two years. Age ranged between 30 and 70 years, although their current living situation was diverse. It was difficult to find research involving individuals' experiences of the Community in relation to the road of drug abuse, hence it is still a relatively unexplored area which made it all the more interesting to study. In this study is the individual's experiences in focus to get a deeper knowledge and understanding of the phenomenon. The result showed the way out of drug abuse may look and be perceived and how the community has been, and is, an important part of this process. The motivation to get out of drug abuse differed for the respondents. Several expressed the fellowship of other former addicts was important to them as a motivation in your own process. To maintain contact with the families and especially their children have also served as support and motivation. The results also showed that their life today works well even if they are still in the process to remain drug-free. Most interview participants are now living drug free and are motivated to continue their journey in life with experiences of abuse that led to and that many of them want to help others who are in the same process.

    Utomhuspedagogik i förskolan: En studie om pedagogers arbetssätt och perspektiv2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Enligt Dahlgren och Szczepanski (2004) är en pedagogik som äger rum inomhus det som förekommer mest i Sveriges förskolor. Författarna ställer sig kritisk mot detta eftersom utomhuspedagogik är en arbetsmetod som utgör grunden för barnen att lära med sinnena i ett utvidgat klassrum utan väggar. Pedagogerna sätter begränsningar för vad barnen får möjlighet och tillgång till i förskolorna. Naturvårdsverket (2011) menar att om pedagogernas beskrivning och åsikter av utomhuspedagogik skiljer sig från varandra kan detta tyda på att pedagogerna har olika upplevelser och erfarenheter av utomhuspedagogik sedan tidigare, vilket kan leda till att pedagogerna arbetar olika med utomhuspedagogik i förskolan. Vi vill därför undersöka pedagogernas beskrivning om utomhuspedagogik och hur dem arbetar med den.

    Syfte

    Vårt syfte med forskningsstudien är att undersöka om tidigare forskning inom utomhuspedagogik överensstämmer med verksamheten i förskolorna.

    Metod

    Vi har genomfört enskilda intervjuer på fyra olika förskolor. Två av förskolorna har en utomhuspedagogisk inriktning medan de andra två förskolorna mestadels spenderar tiden inomhus och inte har inriktning mot utomhusundervisning.

    Resultat

    Resultatet har visat att pedagogerna både beskriver och arbetar olika med utomhuspedagogik beroende på om det är en förskola som mestadels spenderar tiden inomhus eller en naturförskola. Två av de förskolorna i vår studie arbetade mestadels av tiden inomhus och de två andra var naturförskolor som arbetade den huvudsakliga av tiden utomhus. I de två förskolorna som främst spenderade tiden inomhus ser pedagogerna fler möjligheter och endast några svårigheter med att arbeta med utomhuspedagogik. I de två naturförskolorna ser de möjligheter och mer svårigheter med utomhuspedagogik. När de två förskolorna som var mestadels i inomhusmiljö vistas utomhus är det den fria leken som oftast styr vad som ska ske medan de två naturförskolorna är det mer aktiviteter och stationer som styr. Pedagogerna på samtliga förskolor beskriver utomhuspedagogik som ett läranderum utan ramar och att utomhuspedagogik främjar barnens lärande med sinnena eftersom naturen har en variation av redskap som stimulerar barnens fantasi till lek och lärande med oändliga möjligheter.

    Price determinants of the Swedish housing market2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Several studies have been carried out the last decades trying to identify key factors that contribute to the surge in housing prices. Since the deregulation of the Swedish credit market in 1985, the prices have risen more than the CPI and have failed to provide an increased production of real estate. Studies on both domestic market and abroad points out two key variables: GDP and mortgage rates. This study uses an error correction model to find the long run and short term relationship between the variables and prices. The ECM results suggest that the deviation of disequilibrium between housing prices and their fundamentals is corrected over time by roughly 28 per cent per year with GDP and the interest rate as the main influencers in the short term

    Influence of surface roughness on thermography measurement2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This university Bachelor's Thesis was performed to explore the influence of surface roughness on the thermography measurement.

    Thermography is a non-destructive testing method which can be used to detect cracks. However, it is hard to define how the surface roughness influences the emissivity and the result of a thermography measurement, as well as how the angle of the excitation source influences the result. Therefore, this work aims to define how the heating angle and surface roughness influence the thermography measurement, define the relationship between surface roughness and emissivity for the same crack, and define the influence of the angles which composed of the heating source, the direction of crack and the direction of surface roughness on thermography measurement.

    In this report, the theories of radiation and Signal-to-noise ratio (SNR) were explained, clearly. Also, two kinds of experiments were set up. One is focus on how the heating angle influence the thermography measurement, the other is focus on how the angle of the heating source, in relation to the crack direction and the direction of surface roughness, influence the SNR value.

    The conclusions of these experiments are that the heating of a crack increases as the angle decreases (from wide side to narrow side) and the angle ofincreases (from horizontal to vertical). Moreover, the SNR value decreases as the surface roughness increases. For the same surface roughness, the SNR value increases with increased crack angle (0°, 45° or 90°) and with decreased sample position angle (horizontal, 45°or vertical). What is more, the higher surface roughness, the larger the influence of the crack angle and the sample position angle. Finally, when the surface is polish, the crack angle and the sample position angle does not have any influence.

    Robotic 3D friction stir welding: T-butt joint2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Master Thesis was performed in terms of robotic three dimensional friction stir welding with T-butt joint. Friction stir welding (FSW) is a solid state welding method that achieves the weld temperature by friction of a rotating non-consumable tool with the workpiece. Science and technology fast developing requires for higher seam quality and more complex welding joint geometry like 3D welds. In order to acquire high productivity, capacity and flexibility with acceptable cost, robotic FSW solution have been proposed. Instead of the standard FSW machine, using a robot to perform complicated welds such as, three-dimensional.

    In this report, a solution for weld a 3D T-butt joint, which located in an aluminium cylinder with 1.5 mm thickness using a robot, was developed. Moreover, two new paths were investigated in order to avoid the use of two welds to perform this type of joint. The paths were tested on 2D and on 3D (with a 5050 curvature radius) geometries. Both paths had good results. What is more, the parameter developing methods of FSW process, which is composed of necessary parameter setting, positional compensation was introduced. Specially,the study demonstrates how complicate geometry can be welded using a robot. Also,it shows that TWT temperature control is able to acquire high quality 3D welds. In addition, an analysis of the 2D welding and 3D welding was performed, which exposed that, keeping exactly the same welding conditions, higher lateral forces on the tool were found during 3D welding. Basis on the special case in this paper, when the tool goes like "climbing" the sample, the suffering force of tool decreasing with increasing the height(Z position); nevertheless, when the tool goes like "downhill", the suffering force of tool decreasing with decreasing the height (Z position). What is more, in 2D weld, increasing the downforce (Fz) results increasing the lateral forces which can be Fx and/or Fy.

    Finally, the future works suggestions were presented in terms of (1) performing the new paths into a real cylinder, (2) performing tensile test on the paths and comparing it with conventional path which weld twice, (3) researching how the downforce (Fz) influence the Fx and Fy during welding of different 3D geometries, (4) how the cooling rate of backing bar influence the seam quality when it is use the same welding parameters and (5) the effect of performing welds in the same welding temperature achieved with different combination of the tool rotational speed and downforce on the material properties
