An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

The purpose of this essay was to increase the knowledge of and understanding about how teenage girls form their attiutdes towards sexuality and relations. The focus has been on discussing the research-question from four factors of influence chosen by the writers; sexual education, media, friends and family.

The study is based on qualitativ interviews, in so called focusgroups, with all toghether eight girls in the ages 14-15 years, students in the ninth grade. The study has a postmodern feministic approach combined with a fenomenological and hermeneutic position.

The objective of this thesis was to research and gain knowledge about people involved in organized crime in Sweden. By conducting interviews we were able to analyze what factors played a role in an individual's choice to become a member of a criminal gang, as well as to gain an overall picture of these people. The qualitative research was carried out in three different cities in Sweden. Three people, aged between 30 and 60, who are currently members of a gang, were interviewed. In these interviews they shared their life stories in terms of childhood, youth, gang involvement as well as their hopes for the future.The results were then further analyzed to explore any similarities and differences among the participating individuals.

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable.

This thesis is a case study that analyses the seaside resort Ystad Sandskog and its private architecture between 1850 and 1940. The multitude is evident in the area's architecture. The architectural development is analysed with the use of a social historical perspective, including class and hegemony. Regional as well as national affective factors are used in the analysis. Aside from the social aspects, architectural ideological developments, general development of the seaside resort and the area's committee with its prescriptions are all factors considered.By dividing the development in four different chronological phases, which all represents a certain architectural expression exemplified by a selection of buildings and the social class that it accompanies, a culmination in the architectural structural development of Sandskogen is shown.

Background: In scientific literature there are various treatment programs for people with alcohol dependence described, however, are psychosocial factors that promote recovery process described to a limited extent.Purpose: To describe the psychosocial factors that promotes recovery from alcohol dependence.Method: Literature study of ten scientific articles, published between 1999-2011 with both qualitative and quantitative design.Results: According to the literature, the recovery process can be considered to begin when a person with alcohol dependence reached his personal rock bottom. The longer the recovery progresses, the greater are the overall level of performance. Social support is described as an important factor to prevent relapse and reduce the need for professional help. Self-belief and support of self-help groups are described as important to maintaining sobriety. Social support and influence from family members was related to increased ability to analyze and assess their situation during the recovery.

Syftet var att genom journalgranskning kartlägga i vilken omfattning identifiering och dokumentation görs av förekomsten av avoidable factors hos skallskadade patienter, av sjuksköterskor på en neurointensivvårdsavdelning (NIVA), samt undersöka överensstämmelsen mellan dokumentation och monitorvärden rörande intrakraniellt tryck (ICP), cerebralt perfusionstryck (CPP), systoliskt blodtryck (SBT) och temperatur som registrerats via övervakningsutrustningen. Dokumentationen gjordes med ledning av en befintlig guideline. Urvalet var konsekutivt och studien innefattade 25 patienter. Antalet bedömningar i studien var totalt 2176 stycken. Vid 85 % av bedömningstillfällena dokumenterade sjuksköterskan i bedömningsformuläret.

Employees of the criminal correctional system have a duty to notify social services if they suspect that children are exposed to maltreatment, according to Chapter 14, § 1 SoL. Despite the obligation to report, studies show that this is not done at all times. The purpose of this paper is to describe and analyze how the criminal correctional system in Kalmar looks at notification if they suspect that children are exposed to maltreatment. To examine this, we used qualitative research method based on semi-structuring interviews; these were carried out with six employees, working in the criminal correctional system. The answers that emerged during the interviews have been analyzed using Yeheskel Hasenfeld theory of human services organizations, and trough previous research.

Många av dagens dator och TV-spelsljud är anpassade för högtalaruppspelning, i många fall även flerkanalssystem som 5.1 surround och liknande. Få spel är anpassade för uppspelning genom hörlurar och för att få en bra ljudlokalisering i hörlurar behövs ofta någon form av surroundhörlurar. Vi tror att man kan skapa trovärdig (Riktnings)återgivning av ljud i hörlurar genom bara två ljudkanaler genom så kallat binauralt ljud. Vi kommer i detta arbete att beskriva de faktorer som spelar roll i vår stereohörsel, varför de fungerar samt vilka svagheter som finns i detta system. Vi kommer att skapa ett system för att behandla realtidsgenererat binauralt ljud för spel och beskriva de verktyg vi valt och den generella arbetsprocessen.

Datoranvändningen i samhället växer för varje dag. Det är då viktigt att programvara håller hög kvalité, då vissa programvaror styr kritiska maskiner som exempelvis flygplan. Ett sätt att få kvalitativa programvaror är att använda bra utvecklingsverktyg. I detta arbete utvärderas fem olika utvecklingsverktyg: GNAT (Ada), Microsoft Visual C++, Microsoft J++, Borland Delphi och Active Perl. Inriktningen på utvärderingen är mot utveckling av programvara för PLC-system.

The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject.
