    Risk Management in M-Commerce projects: A Case Study of M-Commerce project in Trollhättan2012Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Due to its inherent characteristics such as ubiquity, personalization, flexibility, and dissemination, mobile commerce promises business unprecedented market potential, greater productivity and higher profitability. With this in mind, it is perhaps not surprising that mobile commerce is growing much faster than its fixed counterpart. Unlike e-commerce, m-commerce is personalized and there is a need for a novel approach to evaluating risk management in m-commerce projects.

    Result in the increase of risks management in m-commerce. Besides the business core activities, the increased use of derivative products by both financial and non-financial institutions and recent events or scandals continue to demonstrate the need for enhanced standards and processes of control over risk.

    In this thesis, I attempt to introduce a new method for performing risk analysis studies by effectively utilizing the existing risk management process framework with adoptions of analysis approach in m-commerce projects. It will provide a sequencing of the core part of the risk management process into sub-processes for identify context, identify risks, analyse risks, evaluate risks and treat risks in different respects of m-commerce. Moreover, it seems that the integration of risk management process and some analysis method indeed provided very useful new insights.

    To be able to fulfil the purpose of study, qualitative research method was considered, using an inductive approach of a single case study of m-commerce project in Trollhättan with m-commerce related research literature and scenario for development of restaurant in university west as source of data.

    Based on the analysis, a number of observations were put forward in the conclusion. To begin with the strategy in relation to management structure will be considered. In addition, the role of information technology security is considered in risk management. Meanwhile, the good governance and risk management according to m-commerce application in risk management system and corporate governance are included in the discussion.

    In attempt of risk management in the m-commerce projects, this thesis examines the issues in one case of m-commerce project in Trollhättan not only information secure issues and some technical viewpoints in m-commerce project but also from the project management's perspective.

    The contribution of the thesis will be introducing a new framework/module for performing a risk analysis studies in m-commerce projects domain and a proposal for risk management in the m-commerce projects case of Trollhättan.

    Lifecycle investigation of components made of stainless steel using additive manufacturing2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Additive manufacturing (AM), considered by many to be a revolutionary invention, is a manufacturing process that relies on layer-by-layer technology to build an object. 3D printing has few restrictions on building an object. In this thesis a short description of the traditional manufacturing processes of CNC milling, Forging and AM, in particular, laser wire Directed Energy Deposition, lw-DED which uses laser to melt wire in the process. In this particular case, the use of stainless steel duplex 2205 is chosen because of its broad use and application.

    A hypothetical semi-sphere of 100 kg was considered. The purpose of this work was to identify the energy usage and CO2 footprint of lw-DED which is one of many additive manufacturing alternatives to forging and CNC milling. With the calculated energy usage and CO2 footprints, a sustainable development was assessed andcircular economy perspective highlighted. The results from the project showed that the most of the energy and CO2 footprint occurred in the production of duplex 2205. The advantage of lw-DED is its ability to minimize material waste due to the technology. There is room for improvement and opportunities to implement AM in similar manufacturing processes.

    Potential improvements for launches at Autoliv Sweden AB, focusing on the purchasing process2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    During the summer 2012 a bachelor’s thesis was performed at Autoliv Sweden AB inVårgårda regarding potential improvements on launches, with focus on the purchasingprocess. The activities that were needed to be able to reach the main goal, proposals ofpotential improvements, were divided into three interim goals. The interim goals can beseen as activities along the way containing necessary information that was needed to beable to come up with potential improvements.

    The approach for the thesis was to first do a literature review on value stream mapping, how development projects at Autoliv Sweden AB are performed and on launches in theautomotive industry based on scientific articles. After the literature review a case study wasmade, using value stream mapping as a tool, on one development project at AutolivSweden AB for investigation of the launch. The result of the case study was presented intwo maps over the administrative stream for the components in the development project;one according to project time plan and one according to how the activities in the launchactual were performed.

    Based on the literature and the maps from the case study, three potential improvements, that would be relatively easy and inexpensive to implement, were found; (1) Involve thesupplier more and at an earlier stage in the development project, (2) involve the Logisticsdepartment more and (3) implement control level definition on the development projectsas well, not just the parts.

    The conclusion for this thesis was that if Autoliv Sweden AB decides to implement allproposed improvements both money and time will be saved.

    Searching for Empathy: A Swedish Study on Designing for Seniors2020In: NordiCHI '20: Proceedings of the 11th Nordic Conference on Human-Computer Interaction: Shaping Experiences, Shaping Society, Association for Computing Machinery (ACM), 2020, p. 1-10, article id Article 68Conference paper (Refereed)
    Abstract [en]

    This paper is a call to rethink how we describe groups of usersand create design tools that may influence the design practice and foster specific mentalities. Many times, research literature plays an important part in the design process and decision making, yet the role it has in creating an understanding of the user is seldom discussed. To support a project focusing on designing for seniors, a multidisciplinary team selected relevant literature for the beginning of the design process. The literature selected consisted of 'mental'design tools such as methods, considerations, and design domains to support understanding and designing for seniors. This paper describes the tools suggested by the articles and concludes with a reflection on the effect of the literature we choose on the design process using the project as a design case.

    Automation i Distributionsnät2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As a part of Göteborg Energi’s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid. The intention of the automation is to when a fault occurs, the automation disconnects the faulted cable in the loop and then reconnects, this in as little time as possible in order to not make customers suffer.There are several different theories about how automation can be implemented, the two main principles are local automation and centralized automation. The local automation is implemented at station level with fault detectors that communicate with each other and thus disconnects a fault in the circuit using logic steps. This is the fastest option and Göteborg Energi has already installed several devices in the grid, which could make this option possible to realize. The other alternative is to let the SCADA do the sectionalizing using information from the indicators in the loop. This poses a problem though when the system becomes more complex. The operational staff might have problems with letting the SCADA make its own decisions and thereby lose control over the events in the grid. What the system could do instead is to make a suggestion on how the operational staff should handle the situation. However, the fault durations in this case will end at its best around 2-5 minutes and this makes the customer suffer for a longer time than the earlier principle.Hence, local automation is recommended, partly because it is today implemented in the grid and also because the fault duration is much shorter. This option can, with today’s technology disconnect a single-phase to ground fault without a power failure, and thus does no customer suffer during the fault. This should be supplemented with some sort of residual current compensation of the earth fault in order to remove the active fault current, thus minimizing the probability of a double earth fault or short circuit. Göteborg Energi should contact the suppliers of these devices and find out what they consider appropriate, and implement the technology in a loop as a pilot project to investigate its function.

    Virtual Machine Vision in Computer Aided Robotics2009In: Emerging Technologies & Factory Automation, 2009, p. 1-8Conference paper (Refereed)
    Abstract [en]

    In this paper a concept for Virtual Machine Vision is proposed using a commercial Computer Aided Robotics software called RobCad. The system utilizes ideal virtual cameras and lights for the simulation of a real vision system. Sensory data is sent to a vision software for data analysis. The Virtual Machine Vision together with the simulation model can be used to offline programming of a vision system. Experiments have been performed by capturing images of a test piece both in the virtual environment and in a physical experimental rig. To evaluate the concept, image analysis has been performed on these images using the same vision software. The results from the vision analysis of both the virtual and the real images are compared and show good agreement. The proposed system seems to be very promising and further development is ongoing.

    The introduction of Design into Technology Education2012In: World Wide Workshop in Science Education / [ed] Asdu Ott, Strömstad: Strömstad Akademi , 2012, p. 73-80Chapter in book (Other academic)
    Abstract [en]

    Since 1994 the curriculum for technology education in Sweden aimed at teaching technology from five perspectives: a historical and international perspective; an interactional perspective taking into account the interaction between man, technology and nature; a functional perspective taking into account the ability of technology for storage, transportation, transformation and control; a perspective regarding infra-systemic aspects between components and a system a perspective of making practical constructions and achieving solutions to different technological problems. Since the beginning of the year 2003 a perspective of communication has been tentatively added to these perspectives, as we introduced an aspect of design into our courses at Göteborg University. We thus analyze and apply these six perspectives when we teach design and technology. We regard design as a product and as a process in our course on technology and design. Designing is not only applicable to materialistic products but in an increasing amount to products in the virtual cyber world, which is, to a certain extend, becoming increasingly more integrated with our real life world.

    UX som tankesätt istället för arbetssätt: En studie om hur designers hos SME-företag i den svenska designbranschen förhåller sig till UX-design och användarmedverkan i designprocessen2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to find out if the gap between theory and practice is also visible in the Swedish design industry and how the gap could then be reduced. Previous research describes a lack of UX (User eXperience) work in design processes and a study has therefore been conducted with the aim to formalize guidelines for how companies, which do not include UX and users in their design processes, should develop their UX work in order to offer better artifacts. The results of the study shows that the majority of designers have UX as a design approach. Designers in the industry often know what UX means and why it is important but seems to find it hard to make customers realize the value of the UX work, which force designers to use UX as a way of thinking instead of the way of working. The results of the study presents new guidelines that companies can use to develop their UX maturity and work which is necessary for survival. We can make several conclusions from the result. UX is necessary to deliver high quality products and services to users but restricted by the customers motivation, time requirements and financial resources. Because of that, designers must have rhetorical knowledge and be able to shape and function communication that leads the client to understand the value of UX. If design companies do not involve UX in their design processes, possibly through user tests and demonstrations, the company's risk to losing important competitive advantages. This study provides a good basis for further research in the subject. The study ends with recommendations until further work on topics that were to be done for this study.

    Camera Modelling and Calibration with Machine Vision Applications2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. The camera calibration is a mathematical procedure calculating parameters of the camera model, usually based on several images of reference points. These fundamental parts of machine vision are improved in this thesis. One large part is the development of a generic camera model, GCM, that is accurate, computationally efficient and can be used for both conventional, fisheye and even catadioptric cameras. Different models were used in the past for conventional and  omnidirectional cameras and this is a well-known problem, the solution of which is described in this thesis. The accuracy of camera models is improved by introducing new ways of compensating for different distortions, such as radial istortion, varying entrance pupil point and decentring distortion. Calibration is mproved by introducing newmeans of calculating start estimates of camera parameters, from analysing shapes, sizes and positions of the reference points in the images. These start estimates are needed in order to make the calibration converge. Methods for calculating better reference centre points than the centres of gravity are developed in order to increase the accuracy further. Non-trivial null spaces that occur during calibration are identified. Awareness of these improve the calibration. Calibrations with different camera models are implemented and tested for real cameras in order to compare their accuracy. Certain models are better for certain situations, but the overall performance and properties are favourable for the GCM. A stereo vision welding robot system is developed, using the new model. It determines the geometry of a 3D weld joint, so that a robot can follow it. The same system is implemented in a virtual environment using a simulation software. Such simulation is important since it makes it possible to develop robot vision systems off-line.

    Stereo vision for path correction in off-line programmed robot welding2010In: Proceedings of the IEEE International Conference on Industrial Technology, 2010, p. 1700-1705Conference paper (Refereed)
    Abstract [en]

    The paper describes a versatile machine vision system for correcting off-line programmed nominal robot trajectories for advanced welding. Weld trajectory corrections are needed due to slight variations in weld joints. Such variations occur naturally because of varying tolerances in parts and to heat induced deformations during earlier weld sequences. The developed system uses one camera and a weld tool mounted on the robot hand. As a first step, the whole system, including the camera, is calibrated. Then the system takes images of the weld joint from different positions and orientations, and determines the weld joint geometry in 3D using a stereo vision algorithm and a novel camera model. The weld trajectory is then updated in the robot control system, and weld operation is performed. These steps are repeated for all weld sequences of the work piece. The strategy has successfully been demonstrated for a standard industrial welding robot and a standard FireWire CMOS camera. The maximum deviation of the trajectory found by the system compared to a reference (coordinate measuring machine) is 0.7 mm and the mean deviation is 0.23 mm. Thus, the system shows high potential for industrial implementation. ©2010 IEEE.

    Comparison between Leased Fiber, MPLS and VPN in the scope of Speed, Cost and Security2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a thesis about how speed, cost and security differs between Leased Fiber, MPLS and VPN technologies. To connect different networks across a geographical site have become common in todays society. This is why when enterprises have multiple branches across a state or a country, they would definitely be wanting to connect all these branches together to facilitate data transfer and access between them in order to accelerate the speed of business transactions.

    Nowadays almost all of the businesses have got one or more branch offices which are connected somehow to share services or resources. To fulfil this task there are some different technologies that can be used. Through this study it will be discussed what each technology is capable of.

    This study specially focuses on speed, cost and also how secure these different solutions are. Information about these different techniques have been gathered through different document studies, articles, research studies, service providers and internet to obtain a more accurate result.

    The result of this study shows that Leased Fiber are the most secure, reliable and expensive at the same time as compared to cloud services such MPLS and VPN. However, the cloud services are implemented by most of the enterprises. The main reason is that this solution is cheaper and encryption is used to provide security and integrity. The only drawback is that the link is shared by different nodes.

    Abstract [en]

    As virtual and mixed reality (VR/MR) technology moves steadily towards general availability accessible descriptions of the surrounding theory is desirable. An initial focus on high-level concepts can provide common language for diverse teams, including artists, designers and engineers, helping them to quickly get a sense of basic principles and gain a familiarity with related research for further study. The concepts of synchronized reality and grounded simulation are introduced as helpful starting points for thinking about the design and development of mixed reality systems with optimal presence. This paper provides case studies where recent commercial VR applications are analyzed with the proposed principles in mind, in an attempt to illustrate to developers how to think about design of mixed reality games for optimal presence. © 2019 ACM.

    Learning Models in Online Education: On the Transformation from Tutors to Producers2010In: Proceedings of Global Learn Asia Pacific 2010 / [ed] Zoraini Wati Abas, Insung Jung & Joseph Luca, AACE , 2010, p. 3707-3712Conference paper (Other academic)
    Abstract [en]

    In recent years online and blended learning has scaled up from being a pilot endeavor driven by pioneers, to constituting a large portion of many institutions of higher education. In the process, the conditions for the online teacher has gradually changed, and the situation of today is in many ways problematic where student interaction and dialogue has to stand back in favor of time consuming content production, material delivery, and technical problem solving. This paper draws on the experiences from a Scandinavian University to illustrate how this transition can be understood in the light of rapid technological development in combination with slow evolution of pedagogical models for online education.

    Relationships between Coating Microstructure and Thermal Conductivity in Thermal Barrier Coatings – A modelling Approach2010In: International Thermal Spray Conference and Exposition, ITCS Singapore 2010: 3-5 May 2010,  Singapore, Düsseldorft: DVS Media , 2010, p. 66-72Conference paper (Refereed)
    Abstract [en]

    Fundamental understanding of relationships between coating microstructure and thermal conductivity is important to be able to understand the influence of coating defects, such as delaminations and pores, on heat insulation in thermal barrier coatings. Object-Oriented Finite element analysis (OOF) has recently been shown as an effective tool for evaluating thermo-mechanical material behaviour, because of this method's capability to incorporate the inherent material microstructure as an input to the model. In this work, this method was combined with multi-variate statistical modelling. The statistical model was used for screening and tentative relationship building and the finite element model was thereafter used for verification of the statistical modelling results. Characterisation of the coatings included microstructure, porosity and crack content and thermal conductivity measurements. A range of coating architectures was investigated including High purity Yttria stabilised Zirconia, Dysprosia stabilised Zirconia and Dysprosia stabilised Zirconia with porosity former. Evaluation of the thermal conductivity was conducted using the Laser Flash Technique. The microstructures were examined both on as-sprayed samples as well as on heat treated samples. The feasibility of the combined two modelling approaches, including their capability to establish relationships between coating microstructure and thermal conductivity, is discussed.

    Guia de les escultures de Mollet del Vallès: Metalls, tècniques i curiositats2015 (ed. 1)Book (Other (popular science, discussion, etc.))
    Abstract [en]

    This publication presents a comprehensive study on the current 35 metal artwork pieces located in public spaces of Mollet del Vallès. The sculptures are described from a technical perspective: metallic alloys, joining techniques and protective mechanisms against corrosion are described. However, this research also reveals interesting curiosities and secrets hidden by these sculptures. The information is organised in clear datasheets, where the technical details from the experimental observation and from the official technical project reports are summarised. The symbolisms, anecdotes and curiosities included in this work were gathered during fruitful conversations with authors, authorities and companies involved in the execution of the metal works. The main aim of this work is to invite the reader to stroll into town, to rediscover our heritage, to appreciate it and to make new generations love it.

    Abstract [en]

    Few issues raise such an engagement as parking areas, both by the municipality, property- and car owners. For car owners, it is of great importance where to park his car. Parking is not simply about availability but also about safety, security and how it affects the urban environment.

    When the land will be utilized for building development, there are regulations in Chapter 8, § 9 PBL how parking will be provided. Property owners have an obligation to provide parking space and it shall be arranged in an equitable manner, on the site or near it, which gives an opportunity for shared parking facilities. The guidelines for parking that the municipality has adopted should be the starting point for the extent of that space for parking is required when a building permit review.

    The first thing you should look at, is if the property owner has ability to provide parking space at his own property, but this is not always the best solution in areas such as inner cities. To solve the issue on another property near the property, there are a number of different possibilities for the property owner to resolve the parking issue.

    It may be through an easement, either as official easement or easement agreements. If the facility is intended to be shared by multiple properties as a joint facility, it can be established by Facilities Act. Common parking facilities may also take place at the initiative of the municipality or by a private operator. The finished parking areas can then be leased by a tenancy agreement.

    Parking purchase is another way to solve the parking issue. The public legal obligation to provide parking space is then transformed, through a civil contract, to an obligation to financially contribute to a municipal or private parking facility.

    All solutions have both positive and negative aspects, such as, regulating the costs of operation and maintenance of plant, the agreement can be terminated, etc. which we illustrate by this report.
