The work presented in this report is written at IEIs department on Linköping Institute of Technology. The report aims to increase the assembly efficiency at Wigells AB. The report shall be used as a guide for the implementation of changes at other workstations in the company. Together with Träcentrum in Nässjö, Wigells AB has identified the needs of this study and contacted IEI at Linköping Institute of Technology.In order to implement an efficient assembly line at the company, studies on lean production have been made. This theory has been studied and together with our own views and findings at the company we have analyzed the assembly area.Wigells is a small company that manufactures wood furniture.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).

This thesis presents the question of a possible breakthrough for mobile payment solutions in Sweden. The way payments are made and the way cash is being used in the society is changing. To be accepted as an alternative method, if cash isn't king anymore, the new technology will have to acquire user acceptance. In this thesis a case study of Swish, a mobile payment solution for P2P-payments, is presented. The focus of the study is customer value and technology acceptance of the service.

This master thesis deals with events, dynamics and problems of mediated information seeking within the context of a new information service called "Book a librarian". The study, based on a survey and interviews both in academic and public libraries and participant observations in academic libraries, has its theoretical base in the cognitive theory of information retrieval interaction. The cognitive view is used to throw light upon the need of an ongoing dialogue during the session in order to detect the information needs of the user and to conduct a successful retrieval of information. The communicative interaction is seen as threepart interaction between the intermediary, the user and the information system, where the current cognitive states of all three participants are involved. The study shows that the cognitive obstacles for a successful mediation and information retrieval are mostly connected to participants current knowledge of the subject and of the retrieval techniques.

Urban agriculture is a current topic and this study examines the possibility of cultivating on balconies in the city. The study was performed at Uppsala University and examines, from a structural engineering perspective, how different existing balcony/terrace structures are affected by cultivation. A cultivation balcony defined in the study as a balcony/terrace which is specifically designed for cultivation. Three units of study have been selected according to this criterion. Four factors were examined, these were loads, moisture/water, economy and cultivation.

Denna rapport innehåller en utredning av effektflöden på Uddevalla Energi Elnät AB:s mottagningsstationer och optimering av driftläggning för dess effektkondensatorbatterier och transformatorer.Uddevalla Energi Elnät AB har sedan 30 år haft effektkondensatorbatterier inkopplade nästan hela året och dessa behöver av åldersskäl snart bytas ut. Uddevalla Energi Elnät AB har därför behov av nya rutiner för driftläggning av effektkondensatorbatterier efter det att Svenska Kraftnät och Vattenfall AB har infört nya regler för de reaktiva effektflödena i elnätet.I utredningen om effektkondensatorbatterier har det gjorts en investeringskalkyl med tre alternativ för inköp. Alternativ 1 med central faskompensering på mottagningsstation, alternativ 2 med faskompensering på mottagningsstation kompletterat med faskompensering på abonnentstationer och alternativ 3 med lokal faskompensering på abonnentstationer.  Det framkom i utredningen att alternativ 2: Central faskompensering kompletterat med faskompensering på abonnentstationer är mest lämplig att genomföra.  Det har tidigare konstaterats att det under delar av året har varit låg belastning på några av mottagningsstationernas transformatorer. Det har aldrig utretts om det är lönsamt att stänga av den ena transformatorn under hela eller delar av året.I utredningen om driftläggning av transformatorerna på mottagningsstationerna har det beaktats tre alternativ. Ett alternativ innebär att en transformator körs i tomgång utan last och ett alternativ med en helt avstängd transformator.

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment.I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power.I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level..

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

The aim of this study was to examine how the new established phenomenon of ?Internet drugs? causes challenges to organizations, both individually and in relation to collaboration. The study is based on qualitative semi-structured interviews with representatives from three organizations - one youth police unit, one medical addiction centre and four units working within social services. The theoretical approach that was used is theory about human service organizations, theory about collaboration and new institutional organizational theory. A conclusion is that the current drug classification is problematic and mainly challenging for the organizations that focus on prevention work and early interventions.

The current debate regarding organizational strategies for sustainabledevelopment is influenced by the theory of global governance. Decentralizedstructures of the global society are taken to use in the realization of a sustainabledevelopment. New roles of transnational networks and partnerships raisesquestions of the ability of global governance to co-ordinate and implement longtermsolutions without assistance from centralized and hierarchic structures basedon government. The aim for this thesis is to illustrate the current conditions forwell-functioning networks of sustainable development and examine therelationship between global governance and government. Issues of participation,decision making and compliance are examined by a case study of the Marrakechprocess, a global process to support the implementation of sustainableconsumption and production.

Introduction: The Reading the Mind in the Eyes Test is a widely used test for measuring aspects of social cognition. The aim of the present study was to provide results from a group of typically developing Swedish children (age 9-12) and to compare these results with children and adults in other Swedish and English studies, as well as results from a group of children with Asperger syndrome. Method: A Swedish version of the child version of the test was completed by 83 controls and by six children with Asperger syndrome. Results were compared between the two groups and with data from other studies. Results: The children in the current study did not differ on scores compared to children in the same age group in other studies.

Samordning av de multinationella företagens verksamheter anses vara en allt viktigare källa till konkurrensfördelar. För att en sådan samordning ska möjliggöras ställs det krav på en effektiv kommunikation inom organisationen. Detta försvåras av att de multinationella företagen består av dotterbolag som är verksamma i många olika länder och miljöer.Syftet med denna uppsats är att undersöka hur ABB och Ericsson har agerat för att skapa en effektiv kommunikation mellan sitt svenska moderbolag och sina kinesiska dotterbolag. I fallet med ABB är studien avgränsad till att endast undersöka kommunikationen mellan ABB Power Systems och det kinesiska dotterbolaget ABB Chongqing Transformer Co. Ltd.

This report examines the possibility of optimizing troubleshooting log files generated when constructing new Volvo trucks.
