    Integrated Management Systems: testing a model for integration2011In: 14th Toulon-Verona Conference: Organizational Excellence in Service. Conference Proceedings / [ed] Jacques Martin & Claudio Baccarani., Alicante: University of Alicante , 2011, p. 22-35Conference paper (Refereed)
    Abstract [en]

    Management systems are widely used for creating order, minimising risks and for assuring performance. Management systems are in many occasions integrated since this has been found to be beneficial. In this paper a model for a fully integrated management system (IMS) based on the three axes of level, extent and scope of integration is tested for relevance. The studied system permits the integration of all relevant process dimensions. The research is only in a pilot stage, but the initial results are promising and indicate that there are advantages in using the process view as a base for identifying critical aspects to be managed. A review of the current situation for system integration is studied and the model is subjected to some tests using Sweden as a case. The background study shows that system integration still is limited, especially when comparing with a fully integrated IMS. The feedback from the organisations interviewed is positive and supports continued work with development of the model.

    The transition from higher education to work life: a comparison between a problem-based learning programme and conventional programmes in Higher education2005In: Symposium at the 33nd Congress of the Nordic Educational Research Association (NERA). Oslo, March 2005., 2005Conference paper (Other academic)
    Abstract [en]

    This longitudinal study focuses on the transition from higher education (HE) to worklife. Generally, the transition is considered to have become more complicated due to the changing conditions for work in a supercomplex society. More specifically, there is also still sparse knowledge about how students in PBL programmes cope with the transition process. Previous research on the topic has suggested that there is a need for more complex studies of the relationship between HE and work. The aim of the study is twofold, (i) to describe the way students experience their programme as seniors and later their work situation as novice workers, and (ii) if there are differences regarding these experiences in comparison between a PBL programme (psychology) and conventional progammes (mechanical engineering and political science). The transition from HE to worklife in the three programmes is analysed according to five dimensions; relation to space/areas of operation, identity/tracjectory, professional role characteristics, transition process and relationships between education and work. The results indicate that the PBL-programme is preparing for worklife in a rational way, both regarding generic skills and substantive knowledge. The conventional programmes stand out as preparing for worklife either by providing generic skills or by having a ritual character.

    Abstract [en]

    This longitudinal study focuses on the transition from higher education to working life. Research has hitherto described the transition in rather general terms, and there is still only limited knowledge about how graduates construe themselves as professionals, or how they experience the transition to the sociocultural contexts of working life. In this study, the transition is viewed as a trajectory between different communities of practice. Three different Master’s programmes at Linköping University are focused on and compared: political science, psychology and mechanical engineering. The specific aims are to: (i) identify aspects of identity and knowledge formation as reported by informants, both as...

    A New Moho Depth Model for Fennoscandia with Special Correction for the Glacial Isostatic Effect2021In: Pure and Applied Geophysics, ISSN 0033-4553, E-ISSN 1420-9136, Vol. 178, no 3, p. 877-888Article in journal (Refereed)
    Abstract [en]

    In this study, we present a new Moho depth model in Fennoscandia and its surroundings. The model is tailored from data sets of XGM2019e gravitationl field, Earth2014 topography and seismic crustal model CRUST1.0 using the Vening Meinesz-Moritz model based on isostatic theory to a resolution of 1° × 1°. To that end, the refined Bouguer gravity disturbance is determined by reducing the observed field for gravity effect of topography, density heterogeneities related to bathymetry, ice, sediments, and other crustal components. Moreover, stripping of non-isostatic effects of gravity signals from mass anomalies below the crust due to crustal thickening/thinning, thermal expansion of the mantle, Delayed Glacial Isostatic Adjustment (DGIA), i.e., the effect of future GIA, and plate flexure has also been performed. As Fennoscandia is a key area for GIA research, we particularly investigate the DGIA effect on the gravity disturbance and gravimetric Moho depth determination in this area. One may ask whether the DGIA effect is sufficiently well removed in the application of the general non-isostatic effects in such an area, and to answer this question, the Moho depth is determined both with and without specific removal of the DGIA effect prior to non-isostatic effect and Moho depth determinations. The numerical results yield that the RMS difference of the Moho depth from our model HVMD19 vs. the seismic CRUST19 and GRAD09 models are 3.8/4.2 km and 3.7/4.0 km when the above strategy for removing the DGIA effect is/is not applied, respectively, and the mean value differences are 1.2/1.4 km and 0.98/1.4 km, respectively. Hence, our study shows that the specific correction for the DGIA effect on gravity disturbance is slightly significant, resulting in individual changes in the gravimetric Moho depth up to − 1.3 km towards the seismic results. On the other hand, our study shows large discrepancies between gravimetric and seismic Moho models along the Norwegian coastline, which might be due to uncompensated non-isostatic effects caused by tectonic motions.

    Moho density contrast in Antarctica determined by satellite gravity and seismic models2021In: Geophysical Journal International, ISSN 0956-540X, E-ISSN 1365-246X, Vol. 225, no 3, p. 1952-1962Article in journal (Refereed)
    Abstract [en]

    As recovering the crust-mantle/Moho density contrast (MDC) significantly depends on the properties of the Earth’s crust and upper mantle, varying from place to place, it is an oversimplification to define a constant standard value for it. It is especially challenging in Antarctica, where almost all the bedrock is covered with a thick layer of ice, and seismic data cannot provide a sufficient spatial resolution for geological and geophysical applications. As an alternative, we determine the MDC in Antarctica and its surrounding seas with a resolution of 1°x 1° by the Vening Meinesz-Moritz gravimetric-isostatic technique using the XGM2019e Earth Gravitational Model and Earth2014 topographic/bathymetric information along with CRUST1.0 and CRUST19 seismic crustal models. The numerical results show that our model, named HVMDC20, varies from 81 kg m-3 in the Pacific Antarctic mid-oceanic ridge to 579 kg m-3 in the Gamburtsev Mountain Range in the central continent with a general average of 403 kg m-3. To assess our computations, we compare our estimates with those of some other gravimetric as well as seismic models (KTH11, GEMMA12C, KTH15C and CRUST1.0), illustrating that our estimates agree fairly well with KTH15C and CRUST1.0 but rather poor with the other models. In addition, we compare the geological signatures with HVMDC20, showing how the main geological structures contribute to the MDC. Finally, we study the remaining glacial isostatic adjustment effect on gravity to figure out how much it affects the MDC recovery, yielding a correlation of the optimum spectral window (7< n <12) between XGM2019e and W12a GIA models of the order of ~0.6 contributing within a negligible \pm 14 kg m-3 to the MDC.

    Recovering Moho constituents from satellite altimetry and gravimetric data for Europe and surroundings2019In: Journal of Applied Geodesy, ISSN 1862-9016, E-ISSN 1862-9024, Vol. 13, no 4, p. 291-303Article in journal (Refereed)
    Abstract [en]

    In this research, we present a local Moho model, named MOHV19, including Moho depth and Moho density contrast (or shortly Moho constituents) with corresponding uncertainties, which are mapped from altimetric and gravimetric data (DSNSC08) in addition to seismic tomographic (CRUST1.0) and Earth topographic data (Earth2014) to a resolution of 1° × 1° based on a solution of Vening Meinesz-Moritz' theory of isostasy. The MOHV19 model covers the area of entire European plate along with the surrounding oceans, bounded by latitudes (30 °N–82 °N) and longitudes (40 °W–70 °E). The article aims to interpret the Moho model resulted via altimetric and gravimetric information from the geological and geophysical perspectives along with investigating the relation between the Moho depth and Moho density contrast. Our numerical results show that estimated Moho depths range from 7.5 to 57.9 km with continental and oceanic averages of 41.3 ± 4.9 km and 21.6 ± 9.2 km, respectively, and an overall average of 30.9 ± 12.3 km. The estimated Moho density contrast ranges from 60.2 to 565.8 kg/m3, with averages of 421.8 ± 57.9 and 284.4 ± 62.9 kg/m3 for continental and oceanic regions, respectively, with a total average of 350.3 ± 91.5 kg/m3. In most areas, estimated uncertainties in the Moho constituents are less than 3 km and 40 kg/m3, respectively, but they reach to much more significant values under Iceland, parts of Gulf of Bothnia and along the Kvitoya Island. Comparing the Moho depths estimated by MOHV19 and those derived by CRUST1.0, MDN07, GRAD09 and MD19 models shows that MOHV19 agree fairly well with CRUST1.0 but rather poor with other models. The RMS difference between the Moho density contrasts estimated by MOHV19 and CRUST1.0 models is 49.45 kg/m3.

    Contribution of satellite altimetry in modelling Moho density contrast in oceanic areas2019In: Journal of Applied Geodesy, ISSN 1862-9016, E-ISSN 1862-9024, Vol. 3, no 1, p. 33-40Article in journal (Refereed)
    Abstract [en]

    The determination of the oceanic Moho (or crust-mantle) density contrast derived from seismic acquisitions suffers from severe lack of data in large parts of the oceans, where have not yet been sufficiently covered by such data. In order to overcome this limitation, gravitational field models obtained by means of satellite altimetry missions can be proficiently exploited, as they provide global uniform information with a sufficient accuracy and resolution for such a task. In this article, we estimate a new Moho density contrast model named MDC2018, using the marine gravity field from satellite altimetry in combination with a seismic-based crustal model and Earth's topographic/bathymetric data. The solution is based on the theory leading to Vening Meinesz-Moritz's isostatic model. The study results in a high-accuracy Moho density contrast model with a resolution of 1° × 1° in oceanic areas. The numerical investigations show that the estimated density contrast ranges from 14.2 to 599.7 kg/m3 with a global average of 293 kg/m3. In order to evaluate the accuracy of the MDC2018 model, the result was compared with some published global models, revealing that our altimetric model is able to image rather reliable information in most of the oceanic areas. However, the differences between this model and the published results are most notable along the coastal and polar zones, which are most likely due to that the quality and coverage of the satellite altimetry data are worsened in these regions.

    Estimating a combined Moho model for marine areas via satellite altimetric: gravity and seismic crustal models2020In: Studia Geophysica et Geodaetica, ISSN 0039-3169, E-ISSN 1573-1626, Vol. 64, p. 1-25Article in journal (Refereed)
    Abstract [en]

    Isostasy is a key concept in geoscience in interpreting the state of mass balance between the Earth's lithosphere and viscous asthenosphere. A more satisfactory test of isostasy is to determine the depth to and density contrast between crust and mantle at the Moho discontinuity (Moho). Generally, the Moho can be mapped by seismic information, but the limited coverage of such data over large portions of the world (in particular at seas) and economic considerations make a combined gravimetric-seismic method a more realistic approach. The determination of a high-resolution of the Moho constituents for marine areas requires the combination of gravimetric and seismic data to diminish substantially the seismic data gaps. In this study, we estimate the Moho constituents globally for ocean regions to a resolution of 1° × 1° by applying the Vening Meinesz-Moritz method from gravimetric data and combine it with estimates derived from seismic data in a new model named COMHV19. The data files of GMG14 satellite altimetry-derived marine gravity field, the Earth2014 Earth topographic/bathymetric model, CRUST1.0 and CRUST19 crustal seismic models are used in a least-squares procedure. The numerical computations show that the Moho depths range from 7.3 km (in Kolbeinsey Ridge) to 52.6 km (in the Gulf of Bothnia) with a global average of 16.4 km and standard deviation of the order of 7.5 km. Estimated Moho density contrasts vary between 20 kg m-3 (north of Iceland) to 570 kg m-3 (in Baltic Sea), with a global average of 313.7 kg m-3 and standard deviation of the order of 77.4 kg m-3. When comparing the computed Moho depths with current knowledge of crustal structure, they are generally found to be in good agreement with other crustal models. However, in certain regions, such as oceanic spreading ridges and hot spots, we generally obtain thinner crust than proposed by other models, which is likely the result of improvements in the new model. We also see evidence for thickening of oceanic crust with increasing age. Hence, the new combined Moho model is able to image rather reliable information in most of the oceanic areas, in particular in ocean ridges, which are important features in ocean basins.

    IPv4 mot IPv6 IPsec tunnel2020Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    The exam report studies the difference in how data traffic is affected between IPsec VPN tunnels over IPv4 versus IPv6. The data traffic that is sent over the tunnels is UDP and TCP packets where the speed of data is measured.

    From the produced result values, it can be concluded that IPsec VPN tunnel over IPv4 is better compared to IPv6 as the bandwidth is faster, but the difference is so small that the effect is insignificant.

    A study of the network traffic between Bitcoin nodes2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Bitcoin is a digital cash money system that is decentralized and not controlled by a central authority. It functions as a cryptocurrency across a peer-to-peer network and all nodes in the network have a public registry of who owns what and who transact what. Transactions are secured through cryptography and with time gets locked in blocks of data and added to the blockchain. All transactions and new blocks are sent using TCP protocol to transport these packets to other nodes in the network.

    Bitcoin protocol uses different message types in the communications between the nodes in the network. This work has examined all the message types that are used in the Bitcoin network during two different stages: Downloading of the blockchain to a Bitcoin node versusrunning the node after the blockchain has been downloaded.

    From the produced results, it can be concluded that the network traffic between Bitcoin nodes varies depending on what messages are required to be sent and which phase the node is in.

    Ledarskapsstilars påverkan på inre och yttre motivation: - En kvalitativ studie2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The main purpose of this study was to create an understanding of how varying leadership styles affect the so-called internal and external motivation on employees. The following research question was created: How does the prevailing leadership style of leaders affect the internal and external motivation of employees? Past research studies the relationship between leadership and motivation as one variable. The problem with seeing motivation as one variable is that motivation is affected by various factors and hence should be divided into internal and external motivation. Moreover, studies that study the relationship between internal and external motivation contradict each other’s conclusions. To answer the research question, a qualitative method has been used where semistructured telephone interviews have been conducted. The study consisted of ten respondents, of which eight are employees and two are leaders. Furthermore, four research ethics principles were applied to increase the study’s reliability. The studied leadership styles in the study were transformational leadership, transactional leadership, laissez-faire leadership, and charismatic leadership. According to previous research the following can be stated: Transformational leadership has a positive impact on internal and external motivation. Transactional leadership has apositive effect on external motivation and no effect on internal motivation. Laissez-faire leadership has a negative impact on internal and external motivation. Charismatic leadership has a positive effect on internal and external motivation. This study consisted of two transformational leadership styles, five transactional leadership styles, two laissez-faire leadership styles and one charismatic leadership style. Furthermore, the study concludes that transformational leadership positively affects internal and external motivation because employees are constantly given feedback and encouraged. Transactional leadership style only affects external motivation positively because leaders adapt relationships with employees as a financial exchange. Laissez-faire leadership has no effect on external motivation but can result in both a negative and positive impact on internal motivation. Charismatic leadership has a positive impact on internal and external motivation because the leadership style creates a good relationship between leader and employee.

    Energieffektivisering i köpcentret Sisjö Entré i Göteborg2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Energy efficiency means that energy is used in an efficient way that impacts positively on the environment and society.

    Sisjö Entré is a shopping center which has an annual energy consumption of 1 865 270 kWh, and according to Energy Authority, the recommended value is 1 530 000 kWh per year. That means that energy consumption at the center should reduce by approximately 18 % to comply with the recommended value. The mall consists of 17 stores and the thesis examines five stores which are Toys Я Us, Rusta, Burger King, Babyproffsen and Webhallen. Measurements are taken on ventilation and lighting installations with the aim of studying the loads in the stores that consume the most energy. The goal is to come up with suggestions of actions to reduce energy consumption and costs.

    We concluded that lighting consumes the most energy in the warehouses; Toys Я Us, Rusta, Babyproffsen and Webhallen, while the largest load in the restaurants (Burger King) is the kitchen, which accounts for 75 % of the restaurants total consumption.

    In Rusta, we discovered that the electricity meter showed a lower value than the true consumption. After investigation, we concluded that the fault could be either in the electricity meter or in its current transformer and must be addressed.

    We have given a proposal to replace parts of the existing lighting installations, and given suggestion for sectioning certain parts in some stores. Further, we have given suggestions for reducing operating times on the ventilation units.

    Based on the above proposals and energy calculations, we concluded that these five stores has the potential to reduce the annual energy consumption from 1 865 270 kWh to 1 576 670 kWh, leading to a reduction by 15.5 %. This reduces costs by about 228 000 SEK per year

    Enhancement of an assembly linethrough robotization of the manual station2023Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    This work is being carried out in collaboration with the TYRI Light industry to improve their existing assembly line, which currently has 8 stations. Out of these, three stations are operated by humans, and the rest are automated. The main focus of this project is on the first station, which is currently operated manually. While another master’s student from University West focuses on improving an automated second station and enhancing the fourth station, which is operated by a human worker. The seventh station, which operated manually, requires a human worker because of its complexity and flexibility of human.At this first station, there are two tasks involved. The first task is picking up components and placing them on an empty fixture, while the second task is picking up the finished product from the fixture and placing it on the palletizing process. Currently, it takes 19 seconds for a human worker to complete these tasks before sending the fixture to the next station.The goal of this project is to investigate whether this first station can be improved by using a robot instead. If a robot can perform these two tasks faster than 19 seconds, enhance workplace safety, and handle both tasks effectively without a need for more robots or external assistants. To achieve this, a discussion was made with the TYRI supervisor to select a collaborative robot for this task. To validate the work, ABB RobotStudio simulation software is used. The collaborative robot should be equipped with a specially designed gripper, which is suitable for the collaborative mode. Furthermore, in order to make the gripper suitable for TYRI’s components measurements, it was customized by a mechanism feature, which RobotStudio has.With the help of literature studies and various methods, the successful implementation of the robot was achieved. The robot was integrated outside the assembly line and was able to handle both tasks at the first station. Which indeed improved workplace safety. However, the robot took a total of 30.8 seconds to complete the tasks, which is longer than the 19 seconds goal was aimed for. As a result, the robot didn’t meet the desired cycle time required in this case

    The Brexit event through the Eye of the British newspapers: A study of how the Daily Express and Daily Mail newspapers represented the immigration case during the Brexit event2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Media whether it is visible, audible or readable plays a substantial role when it comes to transferring news and events from all over the world and providing information to the public around the globe. Global news agencies and press representation of many issues, such as wars, conflicts and political dilemmas differ, depending of national origin or political leanings. The events leading up to the Brexit referendum, which took place in the United Kingdom on 23 June 2016, marked a turbulent political moment for the UK. One central issue at the center of this vote was immigration. Nevertheless, how the issues surrounding migration emerged in the news during this period, and especially how media can then be a place for the creation and reinforcement of political debate, have been understudied. To fill this gap, in this study I investigate how the right-wing represented EU and non-EU migrants in UK in light of the rise of populism across Europe. This study looks at two conservative British newspapers "tabloids": Daily Mail and Daily Express. Then with these incidents and two newspapers, this explores how images are rooted in political debate and become representative of it. I conclude that a negative portrayal and debate on migration is reflected in the right-leaning Daily Express and Daily Express. They both tried to create a less supportive and were more hostile debate regarding to migration policy and migrants in UK which helped spread populist thought among people. Furthermore, the thesis demonstrates that images are a crucial element in the development and strengthening of politized discourses.

    Robotize pizza making – Robizza: A conceptual model design and analysis for automating pizzerias2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Food Industry Automation is one of the sectors that took an advantage of industry fourth revolution, where food industry robots start to play a significant role in planting, transporting, processing, and even preparing various dishes. Pizza making is one of the food sectors that is entirely done by food experts and pizza chefs in small and medium business pizzerias, and even though pizza factories have mass production of pizza, they still don’t produce the required freshness and good taste pizza like the one you find it in pizza restaurants. The project studies food industry automation and then designs a conceptual model for robotizing pizza making process, providing a fully automated solution for medium and small pizza-making bakeries. Demonstrating what technologies are required to implement the idea and how to overcome challenges such as quality assurance and preserving hygiene standards adds to that, showing technical limitations and opportunities. The project study is based on theoretical and experimental aspects using an application development kit, Arduino IDE, and simulating the whole process with ABB robot studio simulation.

    Distansarbetets inverkan på unga anställdas work-life balance: En kvalitativ studie om hur unga anställda i ett säljbolag upplever worklife balance2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Digitaliseringen och coronapandemin som utbröts år 2019 var orsakerna till att distansarbete blev allt mer aktuellt på flera arbetsplatser. En snabb förändring genomfördes i samhället då majoriteten av alla organisationer införde distansarbete för att undvika spridning av coronan. I samband med coronapandemin, växte begreppet work-life balance fram. Begreppet handlar om att skapa en balans mellan arbetsliv och privatliv. Syftet med den här studien är att undersöka hur distansarbetet påverkar unga anställdas work-life balance. Den teoretiska referensramen visar att distansarbete kan ha en positiv och en negativ inverkan på anställdas work-life balance. De negativa aspekterna med distansarbete är främst isolering som kan bidra till psykisk ohälsa, övertid och distraktioner i arbetsmiljön som har en negativ påverkan på anställdas work-life balance. De positiva aspekter som nämns är att anställda kan spara tid och pengar på grund av minskad pendling. Anställda kan därtill strukturera upp sin dag, kontrollera arbetsmiljön efter egna preferenser, bli mer produktiva och tillfredsställda i sitt arbete. Vidare har dessa positiva aspekter en god inverkan på anställdas work-life balance. Metoden som används för att samla in data är en kvalitativ forskningsstrategi där respondenter har valts ut med hjälp av ett målstyrt urval. Empirin bygger på 8 semistrukturerade intervjuer där unga anställda besvarar frågor utifrån en bearbetad intervjuguide.

    Studien visar att distansarbete kan ha en positiv och en negativ inverkan på distansarbete. De positiva effekter som studien har kommit fram till är tidsbesparing, möjlighet till att utföra hemmasysslor, tid till att spendera med familj och vänner, förbättrad arbetsmiljö och ökad arbetstillfredsställelse. De negativa aspekter som studien har kommit fram till är övertid, psykisk ohälsa, social isolering och distraktioner i arbetsmiljön. Det insamlade datamaterialet stöds av den tidigare forskningen som lyfter upp liknande aspekter om hur anställdas work-life balance påverkas av distansarbete. Den slutsats som kan dras är att distansarbetet inte bara har en positiv inverkan på unga anställdas work-life balance. Det finns även många negativa faktorer som kan påverka unga anställdas work-life balance under distansarbete.

    Vad händer på förskolegården?: En studie om barns utomhuslek2020Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Leken är spännande, fartfylld, lustfylld, och innehåller ett visst risktagande. Lekdeltagare har ofta ett stort engagemang och full kontroll på vad som händer i leken, men för en betraktare av andras lek kan leken vara svårbegriplig och mycket komplex. Ute på förskolegården händer det mycket och flera människor samlas på en plats där det skapas möjligheter för lek och samspel. Uppkomsten till vår studie var att vi ville veta vad som händer mellan individer i barns utomhuslek.

    Syfte: Syftet med studien är att undersöka barns utomhuslek och på vilket sätt barn och pedagoger interagerar med varandra på förskolegården.

    Metod: Vi har använt oss av kvalitativ metod och genomfört ickedeltagande och halv strukturerade observationer på två småbarnsavdelningar på förskolegården.

    Resultat: Vi fick se en mängd olika lekar på förskolegården med olika aktörer inblandade. I interaktionerna på förskolegården såg vi att kommunikation mellan individer uppstod i olika former i leken. Vårt resultat visar på att både barn och pedagoger använder sig av leksignaler i utomhusleken. Det förekom att både barn och pedagoger stöttade varandra i leken och att de intog olika roller som påverkade leken.

    Har generationstillhörighet påverkan på arbetsmotivation?: En kvantitativ studie om skillnader i motivation mellan Generation Y och Baby boomers2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In today’s labor market, four generations are active, which is more than ever before. Employees from all generations need to be motivated to perform at work. Previous research shows that people of the same generation have experienced similar events and circumstances and are therefore similar to each other. As generations have been influenced by different external factors, they tend to differ in some ways. However, it is not known whether there are differences in intrinsic and extrinsic motivation between generations. People belonging to different generations are expected to work under the same premises and conditions, although there may be fundamental differences in what motivates them.

    The study therefore aims to contribute knowledge about possible differences in intrinsic and extrinsic motivation between generation Y and Baby Boomers. The study is based on previous research on intrinsic and extrinsic motivation, generations, and the Self-determination theory, among others, which resulted in hypotheses that were tested.

    To fulfill the purpose, a quantitative method was used in which a web-based survey was conducted and completed by 149 respondents. A scientifically developed questionnaire called the Work extrinsic and intrinsic motivation scale (WEIMS) was used to measure motivation through 18 different claims. The relationship between the two generations and the variables of intrinsic and extrinsic motivation was then studied. Correlation analyses were also performed between motivation and age as well as motivation and gender, in order to exclude or draw attention to the influence of these factors on the result of the study.

    One conclusion is that Baby Boomers exhibit higher intrinsic motivation than generation Y while generation Y exhibits higher extrinsic motivation than Baby Boomers. However, the differences are not statistically significant. A further finding is that no major differences in motivation emerged between different age groups within the same generation. On the other hand, the relationship between gender and motivation was statistically significant. Women showed higher intrinsic motivation than men while men showed higher extrinsic motivation than women. Finally, it could be concluded that intrinsic motivation is generally higher than extrinsic motivation independent of generational affiliation, age, and gender.

    Quality of nursing care as perceived by cancer patients: A cross-sectional survey in four European countries2017In: Balkan Union of Oncology. Journal, ISSN 1107-0625, Vol. 22, no 3, p. 777-782Article in journal (Refereed)
    Abstract [en]

    Purpose: To explore and compare cancer patients’ perceptions on the quality of nursing care in four European countries. Methods: Data were collected in Cyprus, Finland, Greece and Sweden. The sample comprised 596 hospitalized cancer patients. The quality of nursing care was measured using the “Oncology Patients’ Perceptions of the Quality of Nursing Care Scale” (OPPQNCS). Patient characteristics were also collected. Analysis of variance was used to examine the effects of country on the perceptions of the quality of nursing care. Results: Patients’ age ranged from 18 to 86 years, and 58% were male. The comparison of cancer patients’ perceptions regarding the quality of nursing care between the four countries showed a statistically significant difference in the total OPPQNCS scores (p <0.001) as well as in the subscales responsiveness (p <0.001), individualization (p<0.001), co ordination (p<0.001) and proficiency (p<0.001). The Cronbach’s alpha coefficient for the OPPQNCS ranged between 0.89 and 0.95. A multivariate analysis of variance for the OPPQNCS controlled by respondents’ demographic characteristics revealed that only the patient’s country was significantly related with the patients’ perceptions of quality care. Conclusion: Quality of nursing care as perceived by cancer patients was high, but differed between the four countries. The impact of the clinical status of cancer patients on the quality of nursing care and managerial factors such as staffing/nursing care delivery models that influence the ability of nurses to offer high quality care should also be explored by more focused studies.

    Bemöta den utsatta eleven: En kvalitativ studie om skolkuratorns metoder2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte är att undersöka hur kuratorer arbetar förebyggande för att bemöta barn som blivit sexuellt utsatta via sociala medier/online. Fokus är på ett förebyggande arbete och metoder för att identifiera och arbeta med barn som är i risk för eller redan har blivit utsatta för övergrepp. Studien har en kvalitativ ansats och empirin samlades in genom att intervjuer genomfördes. Studiens respondenter är mellan 27-45 år och de har varit verksamma som skolkuratorer mellan 2 – 9 år. Samtliga respondenter har en akademisk examen som socionom. Den data som framkom analyserades genom en tematisk analys och jag valde tre teman; metodik och förebyggande arbete, samverkan med vårdnadshavare och externa aktörer samt identifiering av elever som utsatts för sexuella övergrepp. Studiens resultat visade att respondenterna använde sig av olika metoder för att bemöta ett utsatt barn, men att den gemensamma faktorn visade på att det var svårt att arbeta förebyggande kring den utsatthet som finns online. En anledning var att det i många fall saknades rutiner eller handlingsplaner för att kunna arbeta förebyggande med sexuell utsatthet. En annan faktor som respondenterna förmedlade var att det största ansvaret ska vara föräldrarnas/vårdnadshavarnas då kuratorer inte har behandlingsansvar för barnen.

    Nybakad sjuksköterska: En litteraturbaserad studie om nyutexaminerade sjuksköterskors upplevelser2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Different studies show that stress is a common feeling that newly graduated nurses experience during the first period in the profession. What causes the stress are high expectations that they have on themselves and the expectations from colleagues, as well as the fear of making a mistake while working as a nurse. Newly graduate nurses go through five stages of development from being novice to expert. The aim of this study was to describe work experiences of newly graduate nurses in hospital ward settings. The research method was a literature study based on ten qualitative articles. Articles were analyzed by using the method of Friberg (2012). Four main themes were identified: experiences of leadership; experiences of the relationship with colleagues; experiences of support; experiences of knowledge level. Colleagues and managers must respond to the needs of newly graduated nurses in an adequate way to create a friendly and supportive working environment, which in turn can contribute to the professional development of the newly graduated nurse. Nursing education should prepare students for professional careers in terms of socialization, leadership and organization.

    De gode viljers land: En venstrefløjskritik af multikulturalismen som svensk statsideologi2018Book (Other (popular science, discussion, etc.))
    Abstract [da]

    Multikulturalisme ses af mange som progressiv og venstreorienteret, og kritikken af den betragtes som reaktionær og racistisk. Denne bog udfordrer denne tankegang og viser – fra et venstrefløjsperspektiv – hvordan den moderne mangfoldighedstankegang tværtimod undergraver fornuft, frihed, lighed og individuel selvbestemmelse. Ved at have et særligt fokus på sær-identiteter og indføre grupperettigheder på bekostning af universel politisk frihed, borgerrettigheder, upartiske institutioner og lighed mellem kønnene er den på kollisionskurs med demokratiets grundværdier. Multikulturalisme er derfor i virkeligheden en konservativ og antimoderne ideologi.

    Migrants and Crime in Sweden in the Twenty-First Century2020In: Society, ISSN 0147-2011, E-ISSN 1936-4725, Vol. 57, no 1, p. 9-21Article in journal (Refereed)
    Abstract [en]

    In 2005, the Swedish Crime Prevention Agency published a report about the link between immigration and crime. Since then, no comprehensive study has been conducted even though Sweden has experienced a large influx of migrants in combination with a rising crime rate. This study conducted by Goran Adamson and Tino Sanandaji is the first purely descriptive scientific investigation on the matter in fifteen years. The investigation (from 2002 to 2017) covers seven distinct categories of crime, and distinguishes between seven regions of origin. Based on 33 per cent of the population (2017), 58 per cent of those suspect for total crime on reasonable grounds are migrants. Regarding murder, manslaughter and attempted murder, the figures are 73 per cent, while the proportion of robbery is 70 per cent. Non-registered migrants are linked to about 13 per cent of total crime. Given the fact that this group is small, crime propensity among non-registered migrants is significant.

    Populist parties and the failure of the political elites: the rise of the Austrian Freedom Party (FPÖ)2016Book (Refereed)
    Abstract [en]

    The author analyses the reasons behind the electoral success of European right-wing populist parties. Using the Austrian Freedom Party under Jörg Haider as a case study and with a richness of primary material, he argues that their success is only partly caused by "racism". It is also, and more prominently, the result of populism – i.e. a critique of the "elite". These parties and their voters should not, then, be labelled as arrogant insiders attacking downtrodden outsiders like immigrants, workers, and minorities. Instead, the right-wingers are more justly portrayed as outsiders and underdogs, raising their anger and frustration against the insiders: the "media elite" and the "leftists and the artists".

    Was National Socialism Anti-Sex?: On Left-Wing Fantasies and Sex as the Dark Matter of Politics2017In: Society, ISSN 0147-2011, E-ISSN 1936-4725, Vol. 54, no 1, p. 23-28Article in journal (Refereed)
    Abstract [en]

    Drawing on an extensive amount of work by other researchers, as well as some literary sources from the time, Goran Adamson discusses the widespread view that Nazism was anti-sex. Indeed, during Nazi rule homosexuality and street prostitution were persecuted, and Jews and “degenerates” were prevented from having sex (not merely by law, but by elimination). However, reported circumstances such as cheap access to condoms, a high number of pregnancies during party rallies, and quasi-religious cultivation of “the Germanic sexual instinct” would suggest that matters may have been much less restrictive for the majority of Germans. The idea of an overall Nazi anti-sex attitude may well have been constructed by intellectuals from the Freudian Left/Frankfurt School, especially their theories of an intimate connection between sexual repression and authoritarianism. Such views gained widespread popularity with the 68’ generation, and they were an essential reason why sexuality came to be considered the cure for all social evils. This overestimation of the significance of sexual liberation, and recent conservative reactions to it, constitute an important part of today’s political landscape.

    Why Do Right-Wing Populist Parties Prosper?: Twenty-One Suggestions to the Anti-Racist2019In: Society, ISSN 0147-2011, E-ISSN 1936-4725, Vol. 56, no 1, p. 47-58Article in journal (Refereed)
    Abstract [en]

    In this piece, Goran Adamson argues that the anti-racist rhetoric is naive and dangerously counter-productive. In theory, they refer to populist parties fueling on the anti-racist elite’s outcries. In practise, however, the anti-racists have forgotten all about it, and seem to believe that right-wing populism will vanish if only it is told off. Shocked, anti-racists say populist parties gain voters despite having certain views. But nobody votes on a party despite its view. True to leftist sensationalism, anti-racists always talk about fascism within right-wing populist parties, thereby overlooking a wide array of other causes for voter appeal. Prone to instant aggression, anti-racists react with fury to any populist provocation, thereby contributing to the meteoric rise of contemporary populism in the West. Instead of conducting a proper analysis, anti-racists say how can people vote on these parties and so on - much like an anti-racist bourgeoisie. Anti-racists, Goran Adamson claims, seem to think knowledge of right-wing populism is compromising, as if you would be tainted by it. In fact, it is the other way around. Criticism requires knowledge - and an ignorant anti-racist might, in the long run, have no power to resist the allure of right-wing populism. People vote on right-wing populist parties, anti-racists maintain, because these people fail to understand. But they claim they do, even though they have reached other conclusions. The responsibility of the financial and political classes for provoking popular reactions is minimized, while the distress among ordinary people is belittled or moralized. The political class ignores a central leftist principle: social behavior has often political/economic explanations. As a direct result of multiculturalism, the pet theory among anti-racists, society’s underprivileged groups - domestic workers and migrants - are in constant conflict instead of uniting against globalization and neoliberal deregulation. This is called divide and rule. In their quest for ideological purity, any anti-EU sentiment, anti-racists claim, is right-wing extreme, hence driving scores of voters into the arms of right-wing populism. These parties are further boosted by the fact that anti-racists sneer at family values and cultural traditionalism. Vocal victims of EU’s austerity measures are dismissed as right-wingers, further fueling political polarization. Popular and populist, anti-racists maintain, is basically the same thing. As a result, democracy becomes politically tainted, and the anti-racist elites are the only safe-guard against unaccountable elites. Right-wing populists never cease to talk about our roots, while multiculturalists never stop talking about roots overseas. Save for that geographic detail, they are two branches of the politicalromantic tree. Right-wing populist parties prosper, but not despite anti-racist efforts, Goran Adamson argues, but as a result of them.

    Förskollärares upplevelse av stress i arbetet2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Enligt arbetsmiljöverket (2017) är det arbetsgivarens ansvar att skydda arbetstagarna från både psykisk och fysisk ohälsa relaterad till arbetet. Trots detta förekommer arbetsrelaterad ohälsa. Förskolläraryrket är enligt Koch (2015, september) en av de yrkesgrupper där flest lider av arbetsrelaterad stress. Detta har under de senaste åren uppmärksammats av bland annat fackliga organisationer och media. Syfte: Syftet med studien är att undersöka förskollärares upplevelser av stress i arbetet och vad som orsakar samt motverkar arbetsrelaterad stress. Metod: Vi har använt oss av en kvalitativ metod i form av semistrukturerade intervjuer med åtta förskollärare från fem olika förskolor från skilda områden i samma kommun. Resultat: Majoriteten av förskollärarna i studien upplever stress i arbetet. Orsakerna varierade liksom upplevelsen av kontroll i arbetet. De flesta upplevde höga krav trots att de uttryckte att de kände stöd från arbetslag och chef.

    Upplevelser som påverkar nattsömnen hos patienter med cancerdiagnos: En litteraturöversikt2020Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: World Health Orginazation (WHO) reported that cancer is the second leading cause of death globally with estimated 9.6 million deaths in 2018. Sleeplessness is a common problem for people with a cancer diagnosis. Humans sleep around eight hours a day which adds up to a third of life. It is the responsibility of nurses to see to the nursing of patients, including sleep. Limited sleep can lead to a greater risk of contracting immunological diseases. In Swedish hospitals there are few guidelines for handling sleeplessness with patients, therefore a study regarding factors influencing sleep negatively is important for the nursing profession.

    Aim: The aim of this study was to describe experiences that influence night sleep for patients with a cancer diagnosis.

    Method: The method for this study is a literature review using quantitative and qualitative articles.

    Results: Among the factors that influence sleep, the most common were pain, urinary and bowel issues, depression, anxiety, social constraints and cancer related loneliness.

    Conclusion: The conclusion of the study is that more guidelines regarding sleep is necessary for the development of nursing.

    Personlighetsdrag och digitala möten: En kvantitativ studie om hur individens personlighet speglas i digitala möten2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Because of covid-19 physical meetings have been replaced with digital meetings. Companies have perceived great advantage with digital meetings and teleworking may therefore continue partially after the pandemic. At digital meetings peoplecommunicate behind a screen and other behaviors may arise in comparison with physical meetings. Previous research has shown that personality traits are a good predictor for behaviors. There was limited research in the field, therefore the study had an exploratory purpose where the relationship between personality traits and individual behaviors at digital meetings were investigated. A quantitative method was used, and a total of 167 people participated in the study (M = 41 years, SD = 13; 131 women). To collect data an internet-based survey was made with self-rated questionnaires. The survey was based on the personality test IPIP-30 and self-designed statements, intended to measure the personality traits in The Big Five and individual behaviors at digital meetings. The data collection was analyzed through a correlation analysis and multiple regression analysis. Our study showed that there was a relationship between personality traits and behaviors at digital meetings and contributed to an increased knowledge of individual differences. For a deeper understanding of the relationship, more studies need to be accomplished and the instrument needs further development. The personality trait conscientiousness had the most meaningful impact of specific behaviors at digital meetings and showed positive correlation with several behaviors. This means that the higher value the individuals have of the personality trait conscientiousness, the more they tend to agree with specific behaviors at digital meetings.

    In the aerospace industry today, super alloys are used in components for jet engines. To increase the efficiency of these engines, through higher combustion temperatures, new materials are developed which maintain their strength at elevated temperatures. The increase in strength as well as the ability to maintain the strength at elevated temperatures, makes them more difficult to manufacture with metal cutting technology.

    The Sector Workshop at GKN Aerospace Sweden in Trollhättan produces a large number of products with a variety of cutting tools. Some of these tools, for a certain product, have been investigated in this work. The products are manufactured from a hard-wearing superalloy which results in extremely high tool wear and high tooling costs.

    To enable improvements in the metal cutting process, a literature study was first conducted. The study focus was to identify information about the various tool wears that occur in metal cutting process of super alloys. Thereafter, specifically selected tools were analyzed. The analysis consisted primarily of a classification of the different tool wear types. In parallel with the tools being classified, measurements were made of the size of wears using a digital microscope.

    The collected data was later used for a statistical analysis, which identified the tool wear type that was the most common. The analysis showed that most of the tools had chipping. Then, to identify where in the machining process the chipping occurred further analyzes were made where the tool wear curves for two cutting tools were plotted. During this analysis to produce the tool wear curves, it was found that the chipping appeared when the tools engaged the workpiece.

    In the later parts of the work, a list of proposal was generated about how the metal cutting process could change to reduce the identified tool wears. One suggestion was to optimize the tool engagement of the workpiece. Also, an optimization of cutting data and especially the spindle speed were also recommended to reduce chipping. This due to some of the chipping could be caused by chatter vibration. For the ceramic tools an increased cutting speed was recommended because machining today was carried out at a much lower cutting speed than research results indicate is necessary for ceramic cutting tools in super alloys. Finally, a checklist for manufacturing personnel was formulated, which could be used to optimize tool wear at GKN Aerospace Sweden.

    "Det finns ju inget annat ämne som är så laddat i skolan": En kvalitativ studie om lärares resonemang kring ämnet religionskunskap och lärares konstruktion av elevers identiteter2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrunden till den här studien är bland annat en ökning av mångkulturalitet i bemärkelsen olika nationaliteter. En annan del av bakgrunden till denna studie är skolans roll i möten mellan livstolkningar och uppfattningar av omvärlden, med religionsundervisningen som en central arena för dessa möten. Utifrån dessa möten är det värdefullt att undersöka hur lärare agerar i förhållande till elevernas livstolkningar, religiösa praktiker och identiteter och hur de planerar sin undervisning. Studien visar även hur lärare resonerar kring uppmärksammandet av olika högtider och traditioner i religionsundervisningen. Studien bygger på intervjuer med fem lärare som arbetar i årskurs 1-6. Resultatet visar på att lärarna använder de muslimska eleverna som kunskapskälla och tolkar elevernas religiösa livstolkningar som kunskap om islam. Lärarna presenterar religionernas högtider och praktiker som enhetliga och homogena. Analysen synliggör hur lärare avvisar föräldrars oro för påverkan genom att hänvisa till religionsundervisningen som faktaförmedling. Det synliggörs även hur lärare konstruerar "normal-muslimer" och "normal-svenskar", där muslimerna framförallt reduceras till kunskapsbärare om islam. Av intervjuerna framgår även att kristendomen har en prioriterad roll i religionsundervisningen och uppfattas som en outtalad norm.

    Estetikens roll för kunskapsutvecklingi de naturorienterande ämnena: En kvalitativ studie genomförd på lågstadieskolor i Irland2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Föreliggande studie är genomförd på lågstadieskolor i Irland. I de irländska styrdokumenten framgår praktiskt-estetiskt arbete vara en central del i de naturorienterande ämnena. Den svenska läroplanen framhåller att estetiskt arbete ska ingå i samtliga av skolans ämnen, dock inte i lika stor utsträckning som i den irländska. Forskning har visat att estetik kan främja elevers utveckling av kunskaper och förmågor i de naturorienterande ämnena. Därför har vi valt att fokusera på analys- och kommunikationsförmågan som inte är lika beforskade i samband med kombinationen estetik och naturvetenskap. Syftet med föreliggande studie är att få kunskap om hur verksamma lärare, på irländska skolor i Irland, erfar att praktisk undervisning med och genom estetik kan främja elevernas utveckling av kunskaper och förmågor i de naturorienterande ämnena.Den metod som använts är enskilda semistrukturerade intervjuer där lärarna fått möjlighet att, genom öppna frågor, delge sina erfarenheter och uppfattningar. Resultatet visar att lärarna uppfattar estetiken som främjande för utveckling av elevernas förmågor och ämneskunskaper. Estetiken uppges kunna användas för att integrera ämnen och göra den abstrakta naturvetenskapen mer konkret för barnen. Kroppen och sinnena anges vara en stor del av det vetenskapliga arbetet som ofta är aktivitetsbaserat. Estetiken visar sig användas för att göra undervisningen mer lustfylld och motivera eleverna till ett vidare intresse för naturvetenskapen. Resultatet visar vidare att lärarna inte erfar att det estetiska arbetet medför några begränsningar för elevernas utveckling av kunskaper och förmågor, men begränsningar i form av bland annat resurser uttrycks förekomma.

    Övervakning: Var går gränsen?: En studie av lastbilschaufförer som arbetar i Bohuslän och hur de ser på IT som hjälpmedel och övervakning på jobbet2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Nowadays companies and organizations are implementing IT-systems that enable surveillances, particularly within the transport business. The implementation within the surveillances systems enables a better security and a more efficient workflow. The systems make it possible for companies to see fuel consumption, the position off the truck and also to plan the most efficient routes. The truck drivers have learned to accept that they are being watched through the companies surveillance systems just because it leads to a more efficient route-planning. The drivers understand why they’re being monitored and they feel safe. Since IT-systems came into the transport business drivers are able to see the fuel consumption and by seeing that they can drive more ecological and save money for their company. The truck driver that works in Bohuslän is well aware that these services are crucial for the companies, by having these systems the companies can compete with the foreign hauliers that takes the same job for a much smaller fee. But where is the limit for acceptable surveillance? We answered the issue by doing interviews in two rounds, first with ten truck drivers then with six. We also did a literature study. The drivers where all driving for companies in Bohuslän. The drivers we interviewed had different experience within the business, some drivers worked at big companies and some drivers worked at smaller companies. By sorting the drivers out we were able to sort out our answers and see if there were a difference in the way the drivers were thinking. We wanted to get knowledge of how different business surveilled their employees and how the employees reacted. So we performed a literature study where we read different case studies from the home care, the sales industry and the elementary school. We compared the result from our study with the result from our interviews. We managed to see that truck drivers generally had more loyal thoughts to their company. The drivers that were interviewed where well aware of the hard competition within the industry. As long as surveillance makes the company more efficient and the surveillance don’t violate their private integrity it´s okay to use it.Keywords: Surveillance, loyal workers, IT-system, competition

    Processability of Laser Powder Bed Fusion of Alloy 247LC: Influence of process parameters on microstructure and defects2020Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is about laser powder bed fusion (L-PBF) of the nickel-based superalloy: Alloy 247LC. Alloy 247LC is used mainly in gas turbine blades and processing the blades with L-PBF confers performance advantage over the blades manufactured with conventional methods. This is mainly because L-PBF is more suitable, than conventional methods, for manufacturing the complex cooling holes in the blades. The research was motivated by the need for academia and industry to gain knowledge about the processability of the alloy using L-PBF. The knowledge is essential in order to eventually solve the problem of cracking which is a major problem when manufacturing the alloy. In addition, dense parts with low void content should be manufactured and the parts should meet the required performance. Thus, the thesis answered some of the important questions related to process parameter-microstructure-defect relationships.

    The thesis presented an introduction in chapter 1. A literature review was made in chapter 2 to 4. In chapter 2, the topic of additive manufacturing was introduced followed by an overview of laser powder bed fusion. Chapter 3 focused on superalloys. Here, a review was made from the broader perspective of superalloys but was eventually narrowed down to the characteristics of nickelbased superalloys and finally Alloy 247LC. Chapter 4 reviewed the main research on L-PBF of Alloy 247LC. The methodology applied in the thesis was discussed in chapter 5. The thesis applied statistical design of experiments to show the influence of process parameters on the defects and microstructure, so a detail description of the method was warranted. This was given at the beginning of chapter 5 and followed by the description of the L-PBF manufacturing and the characterization methods. The main results and discussions, in chapter 6, included a preliminary investigation on how the process parameters influenced the amount of discontinuity in single track samples. This was followed by the results and discussions on the investigation of voids, cracks and microhardness in cube samples (detail presentation was given in the attached paper B). Finally, the thesis presented results of the microstructure obtainable in L-PBF manufactured Alloy 247LC. The initial results of the microstructure investigation were presented in paper A.

    Influence of laser powder bed fusion process parameters on voids, cracks, and microhardness of nickel-based superalloy alloy 247LC2020In: Materials, ISSN 1996-1944, E-ISSN 1996-1944, Vol. 13, no 17, article id 3770Article in journal (Refereed)
    Abstract [en]

    The manufacturing of parts from nickel-based superalloy Alloy 247LC by laser powder bed fusion (L-PBF) is challenging, primarily owing to the alloy’s susceptibility to cracks. Apart from the cracks, voids created during the L-PBF process should also be minimized to produce dense parts. In this study, samples of Alloy 247LC were manufactured by L-PBF, several of which could be produced with voids and crack density close to zero. A statistical design of experiments was used to evaluate the influence of the process parameters, namely laser power, scanning speed, and hatch distance (inherent to the volumetric energy density) on void formation, crack density, and microhardness of the samples. The window of process parameters, in which minimum voids and/or cracks were present, was predicted. It was shown that the void content increased steeply at a volumetric energy density threshold below 81 J/mm3. The crack density, on the other hand, increased steeply at a volumetric energy density threshold above 163 J/mm3. The microhardness displayed a relatively low value in three samples which displayed the lowest volumetric energy density and highest void content. It was also observed that two samples, which displayed the highest volumetric energy density and crack density, demonstrated a relatively high microhardness; which could be a vital evidence in future investigations to determine the fundamental mechanism of cracking. The laser power was concluded to be the strongest and statistically most significant process parameter that influenced void formation and microhardness. The interaction of laser power and hatch distance was the strongest and most significant factor that influenced the crack density. © 2020 by the authors.

    Review of laser powder bed fusion of gamma-prime-strengthened nickel-based superalloys2020In: Metals, ISSN 2075-4701, Vol. 10, no 8, article id 996Article in journal (Refereed)
    Abstract [en]

    This paper reviews state of the art laser powder bed fusion (L-PBF) manufacturing of γ′ nickel-based superalloys. L-PBF resembles welding; therefore, weld-cracking mechanisms, such as solidification, liquation, strain age, and ductility-dip cracking, may occur during L-PBF manufacturing. Spherical pores and lack-of-fusion voids are other defects that may occur in γ′-strengthened nickel-based superalloys manufactured with L-PBF. There is a correlation between defect formation and the process parameters used in the L-PBF process. Prerequisites for solidification cracking include nonequilibrium solidification due to segregating elements, the presence of liquid film between cells, a wide critical temperature range, and the presence of thermal or residual stress. These prerequisites are present in L-PBF processes. The phases found in L-PBF-manufactured γ′-strengthened superalloys closely resemble those of the equivalent cast materials, where γ, γ′, and γ/γ′ eutectic and carbides are typically present in the microstructure. Additionally, the sizes of the γ′ particles are small in as-built L-PBF materials because of the high cooling rate. Furthermore, the creep performance of L-PBF-manufactured materials is inferior to that of cast material because of the presence of defects and the small grain size in the L-PBF materials; however, some vertically built L-PBF materials have demonstrated creep properties that are close to those of cast materials.© 2020 by the authors.

    Influence of laser powder bed fusion process parameters on the microstructure and cracking susceptibility of nickel-based superalloy Alloy 247LC2022In: Results in Materials, ISSN 2590-048X, Vol. 13, article id 100256Article in journal (Refereed)
    Abstract [en]

    Microstructures of material conditions of nickel-based superalloy Alloy 247LC fabricated using laser powder bed fusion (L-PBF) were investigated. Experiments designed in a prior study revealed the L-PBF process parameters for which the material conditions displayed a reduced susceptibility to cracking. Certain process parameters produced material conditions with an increased susceptibility to cracking. In this study, the material conditions were investigated in detail to reveal their microstructure and to determine the cause of cracking. The reason for the transition between a reduced to an increased susceptibility to cracking was examined. The results revealed solidification cracking occurred at high-angle grain boundaries. Solidification cracking may have been promoted at high-angle grain boundaries because of the undercooling contribution of the grain boundary energy. Furthermore, Si segregation was observed in the cracks. Thus, the presence of Si most likely promoted solidification cracking. It was observed that a high crack density, which occurred in the high energy density material condition, was associated with a large average grain size. The fact that certain combination of process parameters produced microstructures with a low susceptibility to cracking, indicates that reliable Alloy 247LC material may be printed using L-PBF by employing improved process parameters. © 2022

    Laser beam powder bed fusion and post processing of alloy 247LC2019In: MS and T 2019 - Materials Science and Technology, Materials Science and Technology , 2019, p. 27-34Conference paper (Refereed)
    Abstract [en]

    Alloy 247LC is sensitive to cracking during laser beam powder bed fusion (PBF-LB) manufacturing. Post processing is thus required to close cracks and achieve desired properties. In this study, samples of Alloy 247LC were manufactured by PBF-LB and subsequently post processed by hot isostatic pressing (HIP), HIP + solution and ageing heat treatments. The microstructure was characterized. Results showed cracks in the as-built condition. Cracks were not detected after HIP. Bright microconstituents were observed in the region between the cells, mainly, because of the partitioning of Hf and Ta into the intercellular region, where they presumably form carbides. What is assumed to be oxides were prominent in the microstructure. Thermodynamic calculations showed rapid formation of ?’ precipitates in the alloy, due to the high total concentration of Al and Ta and this was linked to the high hardness values in the as-built condition. © 2019 MS&T19®

    Scanning electron microscopy and atom probe tomography characterization of laser powder bed fusion precipitation strengthening nickel-based superalloy2023In: Micron, ISSN 0968-4328, E-ISSN 1878-4291, Vol. 171, article id 103472Article in journal (Refereed)
    Abstract [en]

    Atom probe tomography (APT) was utilized to supplement scanning electron microscopy (SEM) characterizationof a precipitation strengthening nickel-based superalloy, Alloy 247LC, processed by laser powder bed fusion (LPBF). It was observed that the material in the as-built condition had a relatively high strength. Using both SEMand APT, it was concluded that the high strength was not attributed to the typical precipitation strengtheningeffect of γ’. In the absence of γ’ it could be reasonably inferred that the numerous black dots observed in thecells/grains with SEM were dislocations and as such should be contributing significantly to the strengthening.Thus, the current investigation demonstrated that relatively high strengthening can be attained in L-PBF even inthe absence of precipitated γ’. Even though γ’ was not precipitated, the APT analysis displayed a nanometer scalepartitioning of Cr that could be contributing to the strengthening. After heat-treatment, γ’ was precipitated and itdemonstrated the expected high strengthening behavior. Al, Ta and Ti partitioned to γ’. The strong partitioningof Ta in γ’ is indicative that the element, together with Al and Ti, was contributing to the strain-age crackingoccurring during heat-treatment. Cr, Mo and Co partitioned to the matrix γ phase. Hf, Ta, Ti and W were found inthe carbides corroborating previous reports that they are MC.
