AbstractOur purpose was to understand how social workers experience the possible complexities that working with economical aid can entail. As an example we chose to focus on long-term economical aid work. We aimed to address the question of which factors could affect their work. In a prior study, done by Dellgran & Höjer (2003) the conclusion was drawn  that  the combination of economical aid, healthcare and schools makeup a third of  practical social work in the terms of the proportion of the amount of social workers, but only 8 percent of the research is done in those areas. Other studies (Stranz, 2007) demonstrate that the research that is done on working with economical aid is deficient.

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

Uppsala University Library owns eight volumes of manuscripts attributed to the academy equerry Johan Leven Ekelund (c.1701?1775). In this thesis, I apply methods from the field of material culture studies in order to establish which of the volumes that formed the donation from Leven to the library mentioned in his will. By mapping certain markers such as places, names and dates I am able to identify to some extent where Leven gained his practical skills and which writers influenced him. By analysing the texts, I draw the conclusion that the manuscripts can be divided into groups aimed for different audiences.

Computer animated faces have found their way into a wide variety of areas. Starting from entertainment like computer games, through television and films to user interfaces using ?talking heads?. Animated faces are also becoming popular in web applications in form of human-like assistants or newsreaders. This thesis presents a few aspects of dealing with human face animations, namely: editing, playing and transmitting such animations.

Denna studie belyser svårigheten för teknik och virtuell geografi att nå ut till mottagaren genom en kartläggning av e-postens geografi. För att skapa förståelse och fånga den osynliga processen bakom e-postens geografi  utgår uppsatsen dels från teorin Actor Network Theory (ANT) och dels från intervjuer.Under studiens gång uppstod ny förståelse för e-postens komplexitet och ledde fram till en reviderad syn. I början av uppsatsarbetet betraktades e-posten enbart utifrån sin funktion som aktant och intermediarie men i takt med att undersökningen fortgick framkom att den samtidigt, utöver dessa funktioner, fungerar e-posten som ett heterogent nätverk med betydelsefulla komponenter såsom aktörer och aktanter. Enligt uppsatsens konklusioner är e-postens trajektoria beroende av den strategi som producenten använder under skapandet av elektroniska meddelanden. Ett kontinuerligt arbete mellan producent och konsument krävs för att e-postens trajektoria ska upprätthållas och leda fram till att det elektroniska meddelande som löper igenom det virtuella nätverket når sitt syfte..

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

This study illustrates how the power relation between the trustee and principals are experienced and maintained in proportion to the missions design. The main focus lies on understanding of how trustee perceives and applies the mission`s cornerstones and how power can be expressed in the relationship between trustees and principals. Nine semi-structured interviews were conducted with trustees whose principals were mentally disabled. The interviews were then analyzed with the support of Foucault's concept of discipline, knowledge, control, surveillance and reward/punishment and Tilly's theory of persistent inequality We have obtained an understanding of the complexity of the assignment regarding the mission`s cornerstones who goes into every other, and all respondents agreed that the cornerstones should be considered as a whole. We concluded that the trustee on the basis of the mission's design possesses a power that is necessary and important to have regarding the relation to his principal and its social network.

The purpose with our essay was to increase our knowledge about what social workers, with experience from working with drug addicts, perceive as the explanations to a person stopping the abuse and succeed in staying drug free. Our framing of the question was:- How do social workers define the term drug free?- How big a roll do the social worker believes she/he has in the process in which a person stops abusing drugs?- How do the social worker work with a person towards getting that person drug free?- What do the social worker believe to be the reason why a person stops abusing drugs?- What do the social worker perceive as helpful for a person to stay drug free?We did qualitative interviews with six social workers. Our main conclusion was that it is difficult to define the term drug free. The reason for stropping the drug abuse can vary, it can be the family situation, "hitting rock bottom", finding love or tiring.

Det här examensarbetet har utförts på uppdrag åt Trollhättan Energi AB (TEAB). Examensarbetet är en utredning beträffande förutsättningar för sammankoppling av TEAB:s och Hjärtum Elförenings elnät.De nuvarande ledningsnäten har radialnät och det innebär att det endast har inmatning från ena ledningsänden. En sammankoppling skulle ge möjlighet till sektionerad drift vilket innebär inmatningsmöjligheter från båda ledningsändar. Det gör att ledningsnätet blir mer säkert, tillförlitligt och effektivt.Ett förslag på ett nytt ledningsnät där delar av TEAB:s och Hjärtum Elförenings ledningsnät är sammankopplade har tagits fram. Med det nya förslaget blir ledningsnätet mer driftsäkert och uppfyller lag- och myndighetskrav.Beräkningarna som ligger till grund för arbetet är teoretiskt utförda.

Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.

A large number of children and teenagers are placed in foster care for various reasons. Social services have a responsibility to follow up youths and ensure that they have the same opportunity for positive development as other young people. A qualitative study was conducted with an abductive perspective by gathering material from social workers in this particular field. The research design of this study is an interview study. The theoretical premise was Bronfenbrenners ecosystem theory and Maslows hierarchy of needs theory.

För att förstå konceptet BYOD behövs först en inblick i hur ett policybaserat system fungerar. Rapporten undersöker och förklarar tre olika Network Access Control (NAC) lösningar som är policybaserade.

In a globalized world, competitiveness is based on the high IP (intellectual property) of our export products and innovations are therefore important for new companies to establish and develop. It´s not enough to just have big international companies but it is also necessary to invest in new companies that can be competitive in the future. By helping entrepreneurs with innovation support in the early stages, new technology-based businesses are established and developed. The purpose of this paper was to examine how innovation support in the early stages affects the establishment and development of new technology-based companies. Furthermore, we investigated how this will affect Sweden's international competitiveness.
