    Vilka ungdomar är det som tar SMS-lån och varför?2008Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    SMS-lån är ett samhällsproblem där olika aktörer är inblandade. Utifrån treforskningsmetoder; kvantitativ- och kvalitativ undersökning samt innehållsanalys av tidningsartiklarna, har synsättet på fenomenet vidgats. Undersökningspopulationen som består av unga SMS-låntagare mellan 18-25 år, var en väldigt svår grupp att nå. Av allt att döma berodde detta på att de är en utsatt och sårbar grupp med ekonomiska svårigheter. SMS-lånet är ett snabbt och lättillgängligt lån vilket stärker ungdomarnas tendens att agera utifrån begär, som i enlighet med Maslows motivationsteori saknar en kognitiv förbindelse. Variationen var stor mellan respondenterna i fråga om vad pengarna användes till, där en del befann sig i den nedersta delen i behovstrappan för att kunna tillgodose de fysiologiska behoven, medan andra konsumerade över sina tillgångar. Låneföretagens systematiska marknadsföring förenklar för ungdomar att ta ett sådant lån med korta återbetalningstider. De ungdomar som inte betalar tillbaka lånet i tid hamnar i ekonomiska svårigheter, vilket påverkar deras liv för flera år framåt i tiden.

    Command Economy as Failed Model of Development Lessons Not Yet Learned: The Case of Eritrea2010In: Journal of Management Policy and Practice, ISSN 1913-8067, Vol. 11, no 5, 49-68 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to identify which economic model is applied in Eritrea. The government claims to follow the market economy model(s), however, the actual practice seems to be different and casts doubts on the government's commitment to market economy. Against this background, the author has examined Eritrea's economic development model. Confirming to his doubts, the author found out that the government is applying a militarist command economy model, however, in an improperly planned, poorly coordinated and extremely mismanaged approach, with its serious negative impacts on the economic, social, cultural, diplomatic and political conditions in the country.

    Leadership Crises and Nation Building in a Politically Turbulent Environment: The Case of the so Called Peoples Front for Democracy and Justice (PFDJ) Central Office in Eritrea2010In: Journal of Leadership, Accountability and Ethics, ISSN 1913-8059, Vol. 8, no 1, 108-123 p.Article in journal (Refereed)
    Abstract [en]

    The purpose of this article is to examine the social dimension of the nation building process in Eritrea. A qualitative case-study method which is composed of primary and secondary data is applied to conduct the research. The main findings show that (i) the social dimension of the nation building process was a complete failure, (ii) the main reason for the failure is the inappropriateness of the leadership to lead the  task properly and (iii) a directive, visionary, participative and interactive leader that possesses, quality, legitimacy, justice, care, competence and character, i.e. honesty, integrity, trustworthiness and principle-centeredness is a leader that can accomplish the task successfully.

    Relations and Networks in the Processes of Establishment of Firms in Transitional Economies: The case of Scandinavian firms in Eastern and Central Europe2006Report (Other academic)
    Abstract [en]

    Focus on the particular entry mode a firm uses to enter a new market, rather than the process of establishment dominates in extant literature. To fill this void, we apply an establishment process model developed from the network approach to illuminate the web of relationship forms embedded in the establishment process of two Scandinavian firms as they attempt to establish themselves in transition economies. In one case, the results show that Statoil’s process of establishment in Estonia was both less time- and resource-consuming because the firm drew support from significant actors in their network of exchange relationships. In the second case, a lack of home and host country support for Scania in Croatia resulted in an arduous and costly process and less stable position in the market, with the firm’s position changing several times as different problems cropped up. In light of the findings from the two cases, theoretical and practical implications for managing the establishment process are discussed.

    Establishment processes in a one party economy: the case of Eritrea2010In: African Journal of Economic and Management Studies, ISSN 2040-0705, E-ISSN 2040-0713, Vol. 1, no 1, 91-111 p.Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to address the issues of how business people perceive the business environment, how government policies impact the environment and how the environment impacts the establishment processes and position development of new firms in the Eritrean market. The process is discussed by keeping a strict focus on the main actors and the activities they carried out, as well as how the available resources are utilized and exchanged in the market.

    Design/methodology/approach – Drawing on the establishment process model developed from the network approach, case studies based on interviews and focus group discussions have been used to shed light on the extent to how government policies and the environment impacts the establishment processes and position development in the Eritrean market.

    Findings – An important conclusion of this paper is that the main obstacle for business establishment is the hostile attitude of the government to the private sector. Another significant obstacle for building a successful position in the market is the state-owned command economy network of relationships. An additional crucial hindrance is the non-existence of a market economy network of relationships that can provide firms in the private sector with the resources they need to perform their operations.

    Research limitations/implications – All firms in this paper have demonstrated that the main obstacle for establishment is the hostile attitude of the government to the private sector. Another obstacle is the state-owned command economy network of relationships, which hinders firms from building a successful position in the market. An additional crucial hindrance is the non-existence of a market economy network of relationships that can provide firms in the private sector with the resources they need to perform their operations. Since the paper is based on case studies and focus group discussions, conducting a similar study on a representative sample of firms selected from a larger population will be very useful.

    Originality/value – This paper makes a unique contribution by focusing on the establishment process in a market, which is regulated, controlled and owned by the one party government. The other unique contribution is that a firm has to identify the secrets of business success and to follow the same strategy.

    Establishment Processes in the Traditional, Complex and Fast Developing Emerging Economy: The Case of Swedish Firms in China2012In: Proceedings of the 2012 International Conference on Marketing Studies (ICMS2012), academic-journal.org , 2012Conference paper (Refereed)
    Abstract [en]

    Applying a qualitative case-study method this article examines the establishment processes of IKEA and HELDING Share Company (HSC). The findings show that establishment in China is a complex, time and resources consuming process. This is because the Chinese culture makes it a pre-requisite to build social networks of harmonious interpersonal relationships, i.e. guanxi_to achieve success. The rules are changing continuously and there is an excessive involvement of the authorities in the economic activities in the market. It thus takes time and consumes enormous resources to understand the problems and to develop strategies to achieve success in establishments. IKEA and HSC developed interpersonal networks (guanxi) with the JV partners and the various influential people (facilitators) in the different phases of establishments. The developed guanxi enabled the two firms to understand and to handle; the cultural constraint, the complicated and continuously changing legal system, the bottlenecks in authorities relationships, the most complex and time consuming bureaucratic structures, the unique style of negotiations, to get operations and import license,  license for the land for running the business and to get various types of assistance in the network development.

    From industrial networks to strategic alliances or vice-versa2009In: International Journal of Business and Emerging Markets, ISSN 1753-6219, E-ISSN 1753-6227, Vol. 1, no 4, 361-386 p.Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is: to highlight the impact of industrial networks on strategic alliances; to determine if alliances help firms to build up new or strengthen existing networks; to find out whether alliances succeed or precede networks. Our findings show that well-developed networks have a positive impact on how alliances function and the results that they can achieve. The other finding is that alliances defend and strengthen networks, and also enable firms to build new ones or penetrate those of their alliance partner(s). The final conclusion is that it is difficult to determine if alliances succeed or precede networks.

    STRUCTURAL ANALYSIS OF A WASHING MACHINE THROUGH ITS LOADING CASES: REDESIGN OF THE TRIPOD AND THE FRONT COVER2011Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This project thesis is developed in collaboration with the mechanical department at University of Skövde, and it is focused in the determination of different loading cases and the application of their results to the optimization of two parts of a washing machine.

     

    The first step in this report is to obtain a numerical model of a washing machine. It includes the assembly in a mechanical software program (Abaqus), and the assignment of the specific boundary conditions and material properties for the problem. Simulation parameters such as mesh size; types of elements, and number of iterations used in the calculations will also be decided.

     

    A study of the different loading cases is carried out with the intention of having a general view of the problem and selecting four specific cases for its application to the reconstruction of the aimed parts (tripod and front cover). This study includes the calculation of the worst relative angle between the tripod and the resultant force for two opposite loads inside the drum. This angle results to be 35º between the arm and the direction of the resultant force.

     

    Through the application of these different loading conditions to this model, the mechanical behaviour of the parts will be obtained and this information will be used in the reconstruction. By mechanical behaviour it is meant to know the maximum level of stress (tension, compression and shear), and deformation (displacement and strain).

     

    Once it is well known which are the most suffering points of the tripod and in the front cover, several different new shapes are created. The parameters considered in this reconstruction were the decrease of volume, the reduction of the level of stress and the deformations. Two of these shapes are chosen and tested in the numerical model, as a checkout.

     

    Finally all these results are presented to the University of Skövde for possible future use.

    Nonrandom pattern of aberrations in 17β-estradiol-induced rat mammary tumors: Indications of distinct pathways for tumor development2007In: Genes, Chromosomes and Cancer, ISSN 1045-2257, E-ISSN 1098-2264, Vol. 46, no 5, 459-469 p.Article in journal (Refereed)
    Abstract [en]

    Estrogens play an important role in breast cancer etiology and the ACI rat provides a novel animal model for defining the mechanisms through which estrogens contribute to mammary cancer development. In crossing experiments between the susceptible ACI strain and two resistant strains, COP (Copenhagen) and BN (Brown Norway), several quantitative trait loci (QTL) that affect development of 17b-estradiol (E2)-induced mammary tumors have been defined. Using comparative genomic hybridization (CGH), we have analyzed cytogenetic aberrations in E2-induced mammary cancers and have found clear patterns of nonrandom chromosomal involvement. Approximately two thirds of the tumors exhibited copy number changes. Losses of rat chromosome 5 (RNO5) and RNO20 were particularly common, and it was found that these two aberrations often occurred together. A third recurrent aberration involving proximal gain and distal loss in RNO6 probably defined a distinct subgroup of tumors, since it never occurred in combination with RNO5 loss. Interestingly, QTL with powerful effects on mammary cancer development have been mapped to RNO5 and RNO6. These findings suggest that there were at least two genetic pathways to tumor formation in this rat model of E2-induced mammary cancer. By performing CGH on mammary tumors from ACI rats, F1 rats from crosses between the ACI and COP or BN strains and ACI.BN-Emca8 congenic rats, which carry the BN allele of the Emca8 QTL on RNO5 on the ACI genetic background, we were able to determine that the constitution of the germ line influences the pattern of chromosomal aberrations.

    Event-Driven Adaptability using IEC 61499 in Manufacturing Systems2012In: Proceedings of The 5th International Swedish Production Symposium, SPS12 / [ed] Mats Björkman, Linköping: The Swedish Production Academy , 2012, 453-460 p.Conference paper (Refereed)
    Abstract [en]

    Different kinds of uncertainty, such as variations in manufacturing capability and functionality, as well as changes in demand, make up a dynamically changing environment for many manufacturing systems of today. The ability to adapt to these unforeseen changes, through dynamic decision-making as well as dynamic control capabilities based on the use of real-time manufacturing information and intelligence, is vital to be able to perform at a competitive level while reducing unscheduled downtime. The event-driven Function Block (FB) model of the IEC 61499 standard, as opposed to the time-triggered and data-driven concept of IEC 61331, supports this approach, making it possible to handle, in a responsive and adaptive way, different kinds of uncertainty. Our objective is to develop methodologies for distributed, adaptive and dynamic process planning as well as machine monitoring and control for machining and assembly operations, using event-driven FBs. The implementation and testing of FB-based control for manufacturing equipment has been successfully realized in prototype systems, with control of both CNC machining and robotic assembly operations. The approach of using IEC 61499 FBs for adaptive control in other applications is also investigated, as an adaptive decision support system for operators at manufacturing facilities is under development. We strongly believe that IEC 61499 will play a major role in the shift to adaptive manufacturing systems.

    Adaptive Assembly Feature Based Function Block Control of Robotic Assembly Operations2012In: The 13th Mechatronics Forum International Conference Proceedings: Vol. 1/3 / [ed] Rudolf Scheidl & Bernhard Jakoby, Linz: TRAUNER Verlag, 2012, 8-13 p.Conference paper (Refereed)
    Abstract [en]

    Many manufacturing systems are exposed to a variety of unforeseen changes, negatively restricting their performances. External variations depending on market demand (e.g. changes in design, quantity and product mix) and internal variations in production capability and flexibility (e.g. equipment breakdowns, missing/worn/broken tools, delays and express orders) all contribute to an environment of uncertainty. In these dynamically changing environments, adaptability is a key feature for manufacturing systems to be able to perform at a maximum level, while keeping unscheduled downtime to a minimum. Targeting manufacturing equipment adaptability, this paper reports an assembly feature (AF) based approach for robotic assembly, using IEC 61499 compliant Function Blocks (FBs). Through the use of a network of event-driven FBs, an adaptive controller system for an industrial gantry robot’s assembly operations has been designed, implemented and tested. Basic assembly operations have been mapped as AFs into Assembly Feature Function Blocks (AF-FBs). Through their combination in FB networks, they can be aggregated to perform higher level assembly tasks. The AF-FBs dynamic execution and behavior can be adaptively controlled through embedded eventdriven algorithms, enabling the ability of adaptive decisions to handle unforeseen changes in the runtime environment.

    The state of the art of cloud manufacturing and future trends2013In: Proceedings of the ASME 2013 International Manufacturing Science and Engineering Conference MSEC2013 June 10-14, 2013, Madison, Wisconsin, USA, ASME - The American Society of Mechanical Engineers , 2013, Vol. 2, Article number MSEC2013-1123- p.Conference paper (Refereed)
    Abstract [en]

    Cloud manufacturing has emerged as a new manufacturing paradigm, which combines technologies (such as Internet of Things, Cloud computing, semantic Web, virtualisation and service-oriented technologies) with advanced manufacturing models, information and communication technologies. It aims to be networked, intelligent, service-oriented, knowledge-based and energy efficient, and promises a variety of benefits and advantages by providing fast, reliable and secure on-demand services for users. It is envisioned that companies in all sectors of manufacturing will be able to package their resources and know-hows in the Cloud, making them conveniently available for others through pay-as-you-go, which is also timely and economically attractive. Resources, e.g. manufacturing software tools, applications, knowledge and fabrication capabilities, will then be made accessible to presumptive consumers on a worldwide basis. After surveying a vast array of available publications, this paper presents an up-to-date literature review together with future trends and research directions in Cloud manufacturing.

    Range Extender for the Renault Fluence Z.E.: Choice of the engine and design of the structural support.2012Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Electric cars have appeared as an alternative to the big pollution caused by internal combustion engine cars. However, electric cars as the Renault Fluence Z.E. are not very sold in the market because of their small range of autonomy. To make this car an attractive option, it is necessary to add a range extender that extends its autonomy. This range extender is based in the addition of a small internal combustion engine to be attached only when the electric autonomy cannot fulfill the trip. A range extender is chosen by means of a comparison between different electric engines sold in the market. By means of a classification tree, the different places of the car where to mount it are compared and the most appropriate is chosen. By using Solidworks, a structure to support the engine and attach it to the car is designed. The result is a Range Extender device to mount in the hitch hook of the Renault Fluence Z.E. that provides an autonomy of around 665 km. This supposes a good solution for the owner of the Renault Fluence Z.E. who needs to cover trips of more than 180 km, the electric autonomy of this car.

    Oljestopp: Utveckling av ett oljestopp2013Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The ecological footprint on the Earth is increasing as more and more industries are built. As a result of the increasing industrialization firmer demands are implemented for the industries to see to it that their toxic waste is taken care of to reduce the environmental impact. The work of this report is made for developing an oil stop prototype for the company Furhoffs in Västra Götalands County, Sweden. The oil stops function is to prevent light liquids that are harmful for the environment from flowing into the drains. The work begins with a market study to study other products on the market. After the initial market investigation and in consultation with Furhoffs development department it was decid-ed that the prototype should have a mechanical seal. Based on the market study seven con-cepts were developed and two were presented to Furhoffs after evaluation. The prototype in the report called concept 7 was chosen for further development. Concept 7 was then developed to meet the standards according to oil-stops. The result of the development process was that Furhoffs decided to proceed with concept 7 from concept level to produce a prototype. In the future the prototype will be further evaluated and then possibly added to the product assortment of Furhoffs.

    ”Såna är dom!”: En socialpsykologisk studie om skillnader mellan unga killars och tjejers stereotypa tänkande och fördomar.2009Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The way man divides his thoughts and sorts them into different boxes, is a cognitive activity which works alike for every person. We split peoplesexterior attributes and characteristic qualities into stereotypes or prejudicemind patterns and treat them along those.

    This study examines through a qualitative method what twelve respondents (six women and six men) between the ages 16-21, think about “intense” conceptions, which may show stereotype or prejudice ways of thinking. There spondents have been chosen regardless ethnic or economic background andare all enrolled in an upper secondary school located centrally in a Swedish big city.

    The purpose is to find out if there are any differences between how some young men and some young women spontaneously think in stereotypical orprejudice patterns. The result is interpreted on the basis of the social cognitive perspective and from out of theories about how people create schemes andprototypes to separate individuals and groups from each other.

    This study suggests that men more easily express their stereotypes and prejudice, while women more often seem to be careful with their stereotypes and prejudice, and end up redefining them. Further in the discussion, aspects involving how the society, if not becoming aware of stereotypes and prejudice, can affect the people representing those stereotypes.

    On the instantaneous energy release rate of the end-notch flexure adhesive joint specimen2004In: International Journal of Solids and Structures, ISSN 0020-7683, Vol. 41, no 16-17, 4787-1807 p.Article in journal (Refereed)
    Abstract [en]

    The energy release rate of the ENF adhesive joint specimen is derived. The resulting formula accounts for the presence of an adhesive layer with a possibly non-linear constitutive relation. The actual form of the constitutive relation need not to be known a priori. It is shown that measurements of both the applied load and the adhesive deformation at the crack tip are needed to determine the instantaneous value of the energy release rate. Experimental results show that the influence of the deformation of the adhesive layer can be substantial. The stability of the ENF-specimen is studied and a method to estimate the critical value of the crack length, accounting for the flexibility of the adhesive layer, is presented. In the analysis, the adherends are modelled as elastically deforming Euler–Bernoulli beams and the intermediate adhesive layer is modelled as a material surface transmitting shear stress between the adherends.

    Stress analysis of axially and thermally loaded discontinuous tile core sandwich with and without adhesive filled core gaps2011In: Composite structures, ISSN 0263-8223, Vol. 93, no 7, 1621-1630 p.Article in journal (Refereed)
    Abstract [en]

    An analytical study is performed to investigate the stress states in an axially and thermally loaded sandwich structure with a discontinuous ceramic tile core. General and simplified models are developed to determine stresses in the constituents of the sandwich structure with and without adhesive in the gaps between adjacent tiles. A general model that allows local bending of the face sheet and a simplified model which assumes uniform through-thickness stress distribution in the face sheets are developed. It is shown that the normal stress in the face sheet decreases when the gap is filled by adhesive, although the tile stress increases. The analytical model shows that normal and shear stresses at the face/core interface can be reduced by filling the gaps between tiles. Filled gaps also elevate the axial stiffness of the structure. Model results are verified by comparison to a previously developed analytical model and finite element analysis. (C) 2011 Elsevier Ltd. All rights reserved.

    Flexural analysis of discontinuous tile core sandwich structure2012In: Composite structures, ISSN 0263-8223, Vol. 94, no 5, 1524-1532 p.Article in journal (Refereed)
    Abstract [en]

    Three-point flexure loading of sandwich beams with a core consisting of discrete ceramic tiles (DTSS) is considered. The tile gaps may be bonded or unbonded (open gaps). The analysis utilizes a layer-wise beam theory approach. The general formulation for the displacements and stresses in the face sheets, face/core adhesive layer, and core is derived. Solutions for stresses and displacements of the beam constituents are obtained from finite element formulation based on analytical solution of the face sheet/tile unit cell. The approach is verified by comparison to stress results obtained from ordinary finite element analysis where each layer is modeled discretely. Effects of load introduction and support conditions on the effective flexural stiffness are examined. It is demonstrated that the face sheets experience substantial stress concentrations at the tile joint locations, especially if the gaps are unfilled. Analysis of beam compliance reveals sensitivity to details of load introduction and support conditions, especially when the span length becomes comparable to the tile length.

    Stability of beam-like fracture mechanics specimens2012In: Engineering Fracture Mechanics, ISSN 0013-7944, E-ISSN 1873-7315, Vol. 89, 98-113 p.Article in journal (Refereed)
    Abstract [en]

    Test specimens used to determine the interlaminar strength of composites as well as the strength of adhesive layers are known to occasionally suffer from instability. Thus, even though the experiments are performed under controlled load-point displacement, the experiments are terminated prematurely by unstable crack propagation. Often there exists a critical crack length which must be exceeded in order to obtain stable crack propagation. In this paper, a general method to assess the stability of beam-like fracture mechanics specimens is developed. Both systems subjected to a single load and the more general situation with several independent loads are treated. A simple formula is derived for the critical crack length for one-parameter loading. The only parameter necessary as input is the compliance of the un-cracked specimen. For the case of non-proportional loading, stability is determined by studying the eigenvalues of a symmetric matrix. Other findings quantified in the paper are the effect of orthotropy, the influence of a flexible interphase layer and the influence of the compliance of the loading device.

    Abstract [en]

    We wanted to find out how the customer wants to be treated by the staff in a clothing store. We have focused on the personal contact between staff and customers. Our report thus focuses not on the physical products but on the staff conduct and behavior towards the customer, based on what it wants. The theory we have used largely reflects how staff should respond, but not how the customer wants to be treated. We decided to find out the customer opinions through a questionnaire survey. To make the report more specific, we also chose to look at the difference between male and female customers. We also studied the difference between age groups of customers from 20 years up to 49 years. To make it easier for the staff to respond to their particular customer group correctly.

    Constitutive Behaviour and Fracture of Adhesive Layers: Inverse Methods and Energetic Balance2004Doctoral thesis, monograph (Other scientific)
    Abstract [en]

    In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. In this context adhesive joining can provide a flexible solution. The method adds little weight to the structure, it allows for material combinations that are not possible to weld, and it provides increased stiffness to the structure as compared to the conventional spot-welding procedure. Moreover, electrolytic isolation of the multi-material joints is achieved.

    In this thesis, experimental methods are developed to determine the complete stress-deformation relation for an adhesive layer loaded in shear. Generally, the stress distribution is non-uniform in the test geometries used. Evaluation of experiments is performed using an inverse method. The idea is to measure the energy release rate as a function of the crack tip deformation. The stress-deformation relation is obtained by a subsequent differentiation. The method is shown to be capable of capturing the complete stress-deformation relation under stable loading conditions.

    A method to accurately determine the energy release rate is needed for the inverse method to be successful. A closed form expression for the energy release rate of the end-notch flexure adhesive joint specimen (ENF) is derived in this thesis. An approximate formula containing measurable quantities is also given. It is shown that both the applied load and the crack tip deformation are needed to determine the instantaneous value of the energy release rate of the ENF-specimen. Experimental results show that the influence of the crack tip deformation can be substantial. An alternative specimen is also analysed theoretically.

    An initial theoretical study on mixed mode fracture of adhesive layers is also given in this thesis. A detailed comparison is made of the mode-mixity obtained using two different, frequently used mechanical models; the beam/adhesive layer model, and the continuum model, i.e. a model neglecting the presence of the adhesive layer. It is tempting to assume that the two methods would produce similar results for the case of a thin adhesive layer. However, this is only the case for geometries which are materially and geometrically symmetric with respect to the adhesive layer. For asymmetric joints, on the other hand, the two models are found to predict fundamentally different values of the mode-mixity. Moreover, the mode-mixity of the beam/adhesive layer model is found to depend highly on the relative stiffness of the adherends and the adhesive layer. This dependency is found to be quantified through two parameters.

    On the determination of constitutive properties of adhesive layers loaded in shear - an inverse solution2003In: International Journal of Fracture, ISSN 0376-9429, Vol. 123, no 1-2, 49-62 p.Article in journal (Refereed)
    Abstract [en]

    A method to determine constitutive properties of thin adhesive layers loaded in shear is presented. The test specimen consists of two adherends joined by the adhesive layer. By loading the specimen antisymmetrically with respect to the adhesive layer a state of pure shear is ensured. To avoid instability the test specimen is designed to give a non-uniform stress distribution in the adhesive layer. This is achieved by using a long specimen loaded at one side. The method is based on an exact inverse solution which is derived utilizing the balance of the energetic forces of the applied loads and of the adhesive at the start of the adhesive layer. The method is intended for determination of both hardening and softening behaviour of adhesives but is confined to monotonic loading

    Flexure of beams with an interlayer: symmetric beams with orthotropic adherends2008In: Journal of Mechanics of Materials and Structures, ISSN 1559-3959, Vol. 3, no 1, 45-62 p.Article in journal (Refereed)
    Abstract [en]

    Analysis of the three-point flexure loading of a symmetric beam configurationconsisting of two identical adherends joined by a flexible layer is presented. Aclosed-form solution is presented in the form of a layer-wise approach, andshows excellent agreement with finite element results. Particular emphasis isgiven to the global beam compliance. The results show that a thin, sheardeformable layer may effectively decouple the responses of the two beams.Furthermore, in contrast to ordinary beams, the presence of an overhangreduces the beam compliance. These effects are quantified and discussed.Experiments on aluminum adherends joined by a rubber layer were conductedover a range of overhang lengths in a three-point flexure fixture, and verygood agreement between measured and predicted beam compliance was noted.

    Flexure analysis of unsymmetric orthotropic beams with an interlayer2009In: International Journal of Solids and Structures, ISSN 0020-7683, E-ISSN 1879-2146, Vol. 46, no 10, 2093-2110 p.Article in journal (Refereed)
    Abstract [en]

    This paper presents a layer-wise stress and deformation analysis of a three-layer beam configuration consisting of two dissimilar orthotropic adherends of different thicknesses that are joined together by a deformable interlayer of finite thickness. Analytical solutions for the case of three-point flexure loading are presented for both compressible and incompressible interlayers. Parametric analysis reveals the influences of asymmetry of moduli and adherend thicknesses, interlayer thickness, and overhang of the beams on the beam compliance. Analytical predictions of beam compliance show very good agreement with finite element results. Experimental measurements of compliance of various unsymmetric beams consisting of aluminum adherends separated by a rubber interlayer were performed in order to validate the analysis. Excellent agreement between measured and predicted compliance values was observed.

    Energy release rate and mode-mixity of adhesive joint specimens2007In: International Journal of Fracture, ISSN 0376-9429, E-ISSN 1573-2673, Vol. 144, no 4, 267-283 p.Article in journal (Refereed)
    Abstract [en]

    Fracture behaviour of adhesive joints under mixed mode loading is analysed by using the beam/adhesive-layer (b/a) model, in which, the adherends are beamlike and the adhesive is constrained to a thin flexible layer between the adherends. The adhesive layer deforms in peel (mode I), in shear (mode II) or in a combination of peel and shear (mixed mode). Macroscopically, the ends of the bonded part of the joints can be considered as crack tips. The energy release rate of a single-layer adhesive joint is then formulated as a function of the crack tip deformation and the mode-mixity is defined by the shear portion of the total energy release rate. The effects of transversal forces and the flexibility of the adhesive layer are included in the b/a-model, which can be applied to joints with short crack length as well as short bonding length. The commonly used end-loaded unsymmetric semi-infinite joints are examined and closed-form solutions are given. In comparison to the singular-field model in the context of linear elastic fracture mechanics, the b/a-model replaces the singularity at the crack tip with a stress concentration zone. It is shown that the b/a-model and the singular-field model yield fundamentally different mode-mixities for unsymmetric systems. The presented closed-form b/a-model solutions facilitates parametric studies of the influence of unbalance in loading, unsymmetry of the adherends, as well as the flexibility of the adhesive layer, on the mode mixity of an adhesive joint.

    A closed-form solution to statically indeterminate adhesive joint problems — exemplified on ELS-specimens2008In: International Journal of Adhesion and Adhesives, ISSN 0143-7496, E-ISSN 1879-0127, Vol. 28, no 7, 350-361 p.Article in journal (Refereed)
    Abstract [en]

    A beam/adhesive-layer model is developed. For this model a closed-form solution method applicable to arbitrary boundary conditions is presented. This enables the solution of a large number of practical problems which may be statically indeterminate. The stress state in the adhesive layer and the adherends of the beam/adhesive-layer model is also scrutinized. The method is exemplified in an analysis of the end-loaded split (ELS) specimen, commonly used to determine fracture energies of adhesive layers. The effect of the flexibility of the adhesive layer on the energy release rate and the critical crack length for stable crack growth is examined. Both symmetric and unsymmetric ELS-specimens are studied.

    Abstract [en]

    A framework is derived for developing constitutive laws for engineering materials. The framework is based on physically motivated assumptions on the mechanical and thermal behaviour of plastically deformed and damaged materials. These assumptions are the starting point in a derivation of the relevant thermodynamic quantities. The procedure reveals important cross-dependencies that have to be considered while developing constitutive equations. A major result of this study is that both deterioration (increase of damage) and healing (decrease of damage) can be modelled in an integrated manner using the same constitutive law. For greater clarity the description is limited to small strain and isotropic behaviour

    Tillgodoses bankernas informationsbehov genom redovisningsinformation upprättad enligt K2 i kreditbedömningen?2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background and problems: It has been an issue for small- and medium sized companies, as accounting standards that they set up their accounts after having been unnecessarily complicated in compared to the needs of the users of its financial statements. Sweden’s efforts to simplify these accounting standards has among other things, been characterized by easing the work for small- and medium size companies. These efforts were called K-projektet, whose purpose partly has been to meet the needs of users of financial statements. K2 is the simplified rule package aimed at smaller companies. Banks are one of the primary users of small companies’ financial statements. K2 is characterized by simplifications, standardization and less reporting obligation. Since banks are demanding a lot of information at a credit decision of a company to make an informed decision, the questions where as follow To what extant do banks use companies accounting information in credit decision? How do financial statements prepared in K2 framework meet the needs of regarded information in credit decisions?Purpose: We examine how the information needs of banks´ are met at credit decisions based on financial statements prepared in the K2 framework. The study aims to increase the understanding and perception of what banks´ demand in the financial information provided by the entities.Method: In the purpose of this study, we wanted to increase the understanding and perception of the chosen topic. A qualitative method aims to do just that, to obtain a deeper understanding of banks´ information demand for credit. A case study includes a complexity of the investigated object, which our study is characterized by because there are relatively few companies that currently apply the K2 in the preparation of accounting information, hence a case study was chosen. The choice to interview the banks was based on that they are the primary users of financial statements in accordance to the K2-regulation.Conclusion: In credit evaluation, accounting is the primary source of information for banks´. Accounting is never a sufficient basis for credit decision for the bank. They have to obtain further information to make an justified decision. The banks´ own assessment of the company as a whole, are based on both hard and soft information which means that regardless of the regulations a company is incorporated by, the banks own internal assessment if a company will be able to repay the credit they will be granted. The most important quality for the bank is that the financial statements are reflecting the fair value, but since K2 is characterized by simplifications, standard solutions and limited choices it creates fewer opportunities for it.Suggestions for further research: An interesting framework to conduct a similar study on, is the K3-framework, since smaller entities may be able to also establish its own financial statements for these regulations. Today is it voluntary to apply K2 this means that few today have chosen to apply the rules. Establishing a new survey when regulations become mandatory for small companies would be a way to highlight the banks´ direct perception of the rules.

    Svensk kod för bolagsstyrning: En studie av bolagen avvikelser från koden2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Accounting and corporate scandals that took place in the 2000s in the United States and several European countries took off in the corporate governance debate. Many countries began to adopt rules designed to develop corporate governance and increase confidence in the business world. Sweden suffered like other countries of accounting scandals, and as a result of this came the Swedish Code of Corporate Governance to rebuild market confidence to the Swedish companies. The first of July 2005 the code was applied in the Stockholm Stock Exchange for all companies on the A-list and the O-list with market capitalization exceeding 3 billion i.e. companies included in the Large Cap. Purpose: The purpose of this study is to examine and analyze how companies on the OMX Stockholm Stock Exchange, Large Cap, deviates from the Swedish code and if they deviate from the same points in the code and how thoroughly these companies explains their deviations. I want to get an understanding of why the code exists and why the companies deviate from it and whether the code works as expected. Methodology: To examine the extent to which companies deviate from the code and which points that the companies differ from, I have studied and observed the companies' annual reports and corporate governance reports. Theoretical Framework: In this chapter, I have raised earlier research that deals with other codes and the principle comply or explain, and the reasons why companies choose to follow or deviate from the code. These studies took place in Germany and the UK.7Empirical foundation: The empirical data consists of annual reports and corporate governance reports of the surveyed 28 companies in the Large Cap from both 2010 and 2011. Conclusions: The conclusion of this study is that the ownership structure is a contributing factor to why companies choose to deviate from the code. Companies with a concentrated ownership tend to deviate from the code. I have also noticed that these companies are owned by Industrivärden and Investor. The companies are also characterized by having strong family owners who own more than 30% of the shares, the owners usually want to have control over the company and that are why they differ from the Swedish Code.

    Modular Locking System to RBS Cabinet2013Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Radio base stations contain equipment which enables the use of cell phones all around the world. ERICSSON is developing these stations and everything connected to the area, such as electronics, software and hardware. In a new project ERICSSON plans to make their hardware modular, to satisfy all their customers around the world even if their preferences differ. The task that was given to us was to develop a modular locking system to the radio base station cabinets.The concept was developed in an integrated working process that focused on a user centered final product. The process included the definition of the problem, preliminary studies of areas which are connected to the problem and a summary of the demands that the customers mediated in a list of requirements. The idea generation generated lots of ideas that later on were developed into different concepts. The concepts were evaluated before the final decision was made together with ERICSSON.The final product is a lifting handle connected to a rod and latch system, which already existed. A new mechanical function was created to make the new handle function with the old system. The locking system is modular and it is possible to choose which way to lock the handle, with a cylinder lock or a padlock. Only one module, the cylinder in the middle, needs to be switched to get the other solution. The other parts are the same; this makes the product modular. The lift handle is an entire new design, developed in the project.

    Push toy: Development of a toy with movement devices associated to the wheels2010Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This is s Bachelor Degree Project report based on the design of a push toy in collaboration with Playsam. The new design consists of a wooden spacecraft.

    The toy can be described as a safe toy appropriated for kids within a range of ages between 1 and 3 years old.  The attractive design of the toy will help the children to increase their imagination. It is a dynamic product that, firstly, seems not to be more than a spacecraft with two wheels that needs another foothold to keep staying up. On the other hand, when the kids take it, they will observe that the product can be displaced by the wheels, and they will find an attractive rotational motion that combines two complementary colours.

    The requirements stated by the company were achieved:

    -       Firstly, the toy must move one of its parts being it connected to the wheels. The product has two main parts. One of them will rotate regarding to the other one when the child drags it thanks to a designed gear system.

    -       Secondly, the toy would be made of wood as well as all the company products. The elected wood was beech wood, getting a similar appearance to the Playsam products aesthetic.

    -       The last requisite of the company was to make the toy easy to handle and manipulate. The anthropometric study organized by the design team guarantees it.  The mediums of the data were considered to build the toy.  It was considered that children less than 18 months will take it by the holes and not the surface.

    The design team bore the European directive 88/378/EEC for Safety of Toys in mind. It was essential to guarantee the safety of the child.

    Demutualization of stock exchanges: A case study : London Stock Exchange and Hong Kong Stock Exchange2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The focus of this study is to evaluate the impact of corporate ownership structure on the overall performance of stock exchanges. This study distinguishes in particular mutual versus demutualized ownership. London Stock Exchange and Hong Kong Stock Exchange are chosen as study cases, because London Stock Exchange is one of the world leading stock exchanges and Hong Kong Stock Exchange is definitely one of the most important emerging market stock exchanges. That is why the results obtained by comparing these two stock exchanges could serve as good indicator in understanding the effects of demutualization process on the whole stock exchange sector and retain the subtle differences in micro-behavior of the stock exchanges undergone the same transformation.

    In this paper the simple descriptive statistics is used as the method of analysis, in association to a profound review of the literature in this area. The data illuminate the fact that demutualized stock exchanges hold a stronger operating performance and a better performance in term of shareholder’s return than mutual exchanges. The result is generally in line with the basic theories in the area of corporate governance and empirical studies in this specific area like Aggarwal (2006), Mendiola and O’Hara (2003) and Hart and Moore (1996).

Studien vilar på en socialkonstruktionistisk grund och vänder sig till läsare inom den symboliskt interaktionistiska diskursen. Den metod som användes var kvalitativa intervjuer. Respondenterna var emellan 19 – 25 år. För att skapa förståelse i respondenternas utsagor användes främst George Herbert Meads (1976) symboliskt interaktionistiska teori om jaget och Zygmunt Baumans (2007) teorier om konsumtionssamhället. Respondenterna i studien upplever att konsumtionssamhället påverkar deras attityder, emotioner, livsstil och identitet. Studiens huvudsakliga slutsats är den att ett konsumistiskt samhälle utför en repressiv påverkan gentemot de unga vuxnas identitetsutveckling. De unga vuxna erbjuds att ge uttryck för sina jag i ett konsumistiskt samhälle som inte uppmuntrar dess medlemmar att reflektera över utförda konsumtionshandlingar.

    Utveckling av stol för café och lunchrum2007Independent thesis Basic level (degree of Bachelor), 15 points / 22,5 hpStudent thesis
    Abstract [en]

    This is a dissertation for a Bachelor Degree Project at the University of Skövde. The project is carried out in cooperation with the company Kinnarps AB.

    The objective of this project was to develop a new chair for café and lunch rooms, which should satisfy the markets expectations and demands and match Kinnarps AB’s assortment today. The project has contained everything from identification of user and customer needs and requirements to evaluation and building of a prototype.

    The result is a chair with a frame of tubular steel and there is nothing like it in Kinnarps AB’s assortment today. The chair has a frame of tubular steel and separate seat and backrest, just like the chairs Jig and Tango as it is intended to replace. The chair’s extraordinary characteristics are that the shape of the backrest enables a good grip and the motion which encourages variation in sitting postures. The motion is new for this kind of chair both in Kinnarps AB’s assortment as well as on the market.

    The product development process is an iterative process which can be described with the activities: identification of customer requirements, product design specification, initiation of concept solutions, evaluation, embodiment design and detail design. Knowledge about the customer requirements and needs is fundamental to a successful product. The result of the market research showed that the new chair should be a comfortable and inviting chair which is lightweight and simple with a timeless design and organic shape. It also came to our knowledge that it is very important that the chair is stackable, possible to hang on a table and linkable.

    Different researchers’ literatures have been studied and an analysis has been made in SAMMIE to ensure that the chair has good ergonomics. This is a very important quality but often an unspoken requirement that is taken for granted.

    The result was carefully evaluated during and after the building of the prototype. Kinnarps AB will also make further analysis and quality tests.

    This project has hopefully resulted in a chair with good quality and a potential to participate in the competition on the market.

    Function Block Environment in Wise ShopFloor: Graphical User Interface2012Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Nowadays, accomplishing real time information applications is one of the goals that customers are looking for in the market. Furthermore, two essential features are required in this society to ensure the success of these applications: reusability and interoperability. The new standard of Function blocks [FB] is one efficient way to reach them. This new standard, whose use has considerably  increased,  consists  of  a  large  number  of  functionalities  divided  into  distributed shorter  codes.  In  fact,  that  is  why  function  blocks  are  different  from  other  programming languages:   it   works  with   short   distributed   functionalities   interconnected   among   them. Therefore,  for  this  reason  function  blocks  are  used  in  distributed  automation  systems.  The function  block  standard  is  formally  specified  in  IEC  61499,  for  distributed  Industrial  Process Measurement  and  Control  Systems  (IPMCS).  It  is  worth  of  mentioning  that  function  blocks design is usually carried out graphically (interconnecting data and events within a FB network), whose clarity and easiness are always significant requirements, as in any visual system. On  the  other  hand,  web-based  application  development  is  getting  more  and  more  common during the last years because of its efficiency, portability and flexibility. It also provides many advantages to users, in real-time monitoring, real-time manufacturing, or even remote control. These are what companies are looking for in the 21st century. Nevertheless, combining web-based programming with function blocks can be the key to companies’ success.  This project consists of implementing a web-based function block environment for IEC 61499 compliant  control  systems  development.  It  would  be  a  proper  way  to  meet  the  above mentioned    customer    requirements    (efficiency,    portability,    flexibility,    reusability    and interoperability).  The  main  objective  of  the  five-month  project  is  to  develop  a  web-based function block environment with a user-friendly graphical interface. The challenges include:   - Carrying out research on Function Blocks and its run-time environment. -  Implementing  an  easy-to-use  graphical  interface  for  creating,  saving  and  editing different types of function blocks (basic FB, composite FB and applications). - Introducing iconic design and visual presentation of function blocks and connections via drag-and-drop. -  Developing  an  application  to  generate  eXtensible  Markup  Language  (XML)  files, allowing  the  exchange  of  files  between  different  tools  and  devices  of  different vendors. This web-based function block environment will be used at Volvo Cars and Sandvik AB as a part of  a  big  research  program.  It  is  anticipated  that  the  function  block  environment  will  be extended  and  applied  to  a  real-time  decision  support  system  for  walking  workers  where important events or tasks will be distributed to the right person at the right time.

    Har kunden alltid rätt?: Hur hanterar butiker klagomål från missnöjda kunder?2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det är ett vanligt förekommande problem inom handeln att kunden alltid hävdar sin rätt vid klagomål. Det är särskilt ett problem för butikerna som vill ha nöjda kunder samtidigt som de måste sätta gränser för att hålla butikerna lönsamma. Butikerna måste därför ha god kunskap om hur man ska kunna sköta klagomålshanteringen på bästa sätt. För att ta reda på hur olika butiker hanterar klagomål, har intervjuer genomförts med både butikschefer och säljare i fyra butiker inom elektronik- och sportbranschen. Genom dessa intervjuer fick vi reda på hur de anser att man ska ta hand om missnöjda kunder, samt vilken utbildning de har inom detta område. Att både butikschefer och säljare tillfrågades, var för att se om det fanns någon skillnad i deras uppfattningar om klagomålshantering. Syftet med undersökningen var att ta reda på vad butiker anser om begreppet ”kunden har alltid rätt”, samt ta reda på hur butikerna hanterar de missnöjda kunderna som klagar. Vi ville veta vad butikerna gör för att tillmötesgå kundernas klagomål och vad de anser att kunden har rätt till. Vi vill även ta reda på om de vet vad kunder har rätt till enligt lag. Utav undersökningen kom vi fram till att det finns dålig utbildning i klagomålshantering, och att de tillfrågade anser att man bäst lär sig detta genom rutin. Butikerna verkar ha lyckats med sin hantering, då de kunder som varit missnöjda ändå stannar kvar som kunder i butiken. Vi fick även reda på att det viktigaste, när man tar emot klagomål från kunder, är att visa förståelse och lyssna på kunden. Vi såg även att uppfattningarna om hur missnöjda kunder ska hanteras skilde sig mellan butikschefer och säljare. Säljare i elektronikbutikerna menar att de är alldeles för generösa när det kommer till att återgälda missnöjda kunder. I sportbutikerna är säljarna striktare genom att de följer lagar och vissa rutiner i dessa situationer. Alla ansåg även att kunder utnyttjar begreppet ”kunden har alltid rätt” och över lag tycker ingen av butikerna i undersökningen att detta uttryck är riktigt, men menar att kunden ska tro det.

    Utveckling av vippgunga för barn i åldrarna 1-3 år2013Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    During the spring of 2013, Emilia Andersson, a student in product design engineering at University of Skövde, carried out a product development project in cooperation with HAGS Aneby AB. The aim of the project was to develop a seesaw adapted for children aged 1-3 years. The goal was to develop a seesaw that could be sold worldwide and meet the American standard and European standard for playground equipment.

    The project began with a pre study and a theory phase, which included literature review and competitor analysis and information were gathered to gain a deeper knowledge of the subject. Later on ideas and concepts were generated, which then through evaluations as user testing lead to a final concept. The concept was evaluated with for example strength calculations and an anthropometric analysis.

    The final seesaw can, despite adjustment for the age group, not only be use by 1-3-year-olds, but also by older children, this thanks to the design and the handles that provide extra play values.
