EMC problematik och el-kvalitet i elkraftnät
The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.
Svensk-Rysk gradmätningsexpedition på Spetsbergen 1898-1914 : Ekonomiska överväganden och förändrade attityder med aspekt på åren 1898, 1902 och 1914
This study concerns the complete oeuvre by the British author Helen Zahavi: Dirty Weekend (1991), True Romance (1994), and Donna and the Fatman (1998). Her novels are here read as a trilogy dealing with the dialectics of gender and violence in 20th century discourse, drawing on theories of how the construction of subjects is produced by power, of the relation between power and sexuality.The heroines of Zahavi?s novels try their best to move about in a world where their freedom of movement is limited to their female identity. In Dirty Weekend the protagonist tries to shoot her way out, claiming revenge on every man that is forcing himself upon her. She gains some freedom of movement by refusing subordination, but does not really change the order of power.
Tillförlitlighet i Stockholms elnät : En analys med hjälp av Tekla NIS
Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.
Utveckling av en ljudsimulator med anva?ndarcentrerad design : Tilla?mpad matematik fo?r ba?ttre konsertupplevelse
The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Smarta lokala energisystem, Vision-Teknik-Tillämpning
The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
Medarbetarsamtal : -en studie om medarbetarsamtalets betydelse som verktyg för utveckling inom offentligsektor
Performance appraisals- a study of the performance appraisals significance as a tool for development in the public sector.Anders Larsson and Åsalill OlssonPerformance appraisals have been given a central role in leading businesses in the public sector and are seen as a tool to create development opportunities and achieve better results. This has resulted that performance appraisal in many organizations takes up capacity and time. This was the starting point of our interest to study whether the time spent on performance appraisals effectively pays for itself in the organization, in other words whether the effects expected actually are achieved. The paper examines first line managers` views on staff appraisal purposes and effects of a function within the Landstinget. The survey design, methodology and transaction are of qualitative and quantitative method with three different sources: literature review of previous research, interviews with first line managers in Landstinget Västmanland and the results from an employee satisfaction survey conducted on behalf of Landstinget Västmanland.
Leaf area index in Vittelaria Paradoxa parklands in Burkina Faso estimated by light interception and leaf sampling
Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.
Armlängdsprincipen och Statens kulturråd: En fallstudie om maktfördelning i svensk kulturpolitik
This Masters Thesis is about the Swedish National Council for Cultural Affairs and the arms length principle. The principle is used to explain the separation of power between two parts with a common interest. The main purpose is to elucidate if, and if so in what way, the arms length principle can be used to explain the relation between the National Council for Cultural Affairs and the Ministry of Education and Culture, i.e. the Swedish government, but also to examine the structures of power and relations within the Council. In the thesis we show that in the field of cultural policy the content of the arm lengths principle varies due to the many interpretations of the meaning.
Ungdomars självidentitet, arbetslöshet, kontakt med socialtjänsten och arbetsmarknadsinriktade insatser : en studie utifrån ungdomars berättelser
This essay examines how a group of five youths? self identities are affected by unemploy-ment, contact with the social services and by labour market interventions. In Sweden youth employment has been regarded as a social problem. Arbetslinjen that could be translated into the work model or the work line influences and is a necessity for the Swedish welfare system. With a hermeneutic scientific philosophical position the method used to examine this has been to interview the youths, in the age of 18-25, individually.
Vad kvinnor vill ha : en studie om unga mäns självpresentationer på dejtingsajten Spray Date
Title: What women want ? a study about young men?s self-presentation on the on-line dating site Spray Date.Authors: Anna Tuvehagen & Josefin HultTutor: Lena Widding-HedinPurpose: Our main purpose was to identify implicit norms and ideals for masculinity in young men?s advertisements on the on-line dating site Spray Date.Questions: How do the men present themselves on Spray Date and what do they accentuate in their advertisements? What kind of relationship do the men hope to establish and what qualities and attribute do they look for in women? Are there any notable differences and similarities regarding our findings of ideals and the ones in previous research?Method: In order to answer our questions we chose 100 advertisements made by men in the age 18 to 25. To analyse the advertisements we used a qualitative content analysis, however we have some quantitative elements.Main results: The men in our study are searching for love on Spray Date and usually describe themselves as nice, cheerful, decent guys with good sense of humour. Although, spare-time interests and activities are what the men mainly focus on. Their interests are broad and all sorts of combinations occur why it is difficult to place the men in categories.
På vems villkor? : en studie om hur personer utan hem upplever socialtjänsten
The purpose of this paper is to study how people without home experience social services and how they experience their space of action when they meet social services. In order to answer these questions, a qualitative approach has been used. The empirical material consists of five interviews with people who have contact with social services because they are homeless. To support my analysis of the space of action for the persons being interviewed, I?ve used two theoretical perspectives, power analysis by Michel Foucault and Rational Choice.
Risk eller Resurs: En studie av hur riskbegreppet konstrueras i den svenska kärnkraftsdebatten
Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.
- För vi har slutat nian, fyfan va' vi é bra! : En kritisk diskursanalys av grundskolans fostran från Lgr62 till och med Lpo94
I have studied the curriculum for the compulsory Swedish school, from the curriculum from year 1962 when the Swedish grundskolan became a reality, to the curriculum from year 1994, the one in practice today. My primary interest has been what the curriculum says about bringing up the Swedish youth. My theory has been the British analyst Norman Fairclough?s Critical Language Studies. His thoughts about actual discourse, type of discourse and order of discourse has led me through out this essay.
Energibolagens framtida datainsamling
The Swedish energy companies have several different systems for data collection
of the energy consumption of their clients. Often computerized remote meter
readers are put in practice in order to register the energy consumption of
large companies. The majority of household clients, however, are read off by
the assistance of manual methods.
Household power consumption is read off once a year. As a result, these clients
are not debited for their actual consumption; their invoices during the year
are the result of estimations. At times when the electricity supply system is
highly loaded, electricity is more expensive.
