This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Denna rapport jämför prestandan mellan state-of-the-art AI-botar i racing spelet TORCS och en AI-bot som kör med hjälp av ett artificiellt neuralt nätverk (ANN-bot). ANN-boten, som implementerades som en del av arbetet, använder en feedforward arkitektur och backpropagation för inlärning. Ett separat program som användes för att träna det neurala nätverket med träningdata som spelats in från TORCS implementerades också. Som state-of-the-art AI-botar användes AI-botar som har använts i en tävling. De fyra AI-botarna testades på åtta olika banor och data om hur lång tid varje varv tog och hur snabbt AI-botarna körde sparades och sammanställdes.

HMS Networks AB develops, produces and sells communication technology for industrial automation. The product handles communication between a variety of protocols. The product treated in this project is an Anybus X-gateway Modbus-TCP Master/Client and this module is currently configured from a web-based interface. In doing so, the flexibility for handling protocols is limited to what the company chooses to add to the interface. Therefore the company had a request that the flexibility should be extended using a script language.

The aim of this study is to describe and understand the reasons to why people choose to become foster parents. By using the theory of action we wanted to investigate their intentions rather than their motives. The questions we wanted to answer where: How do the foster parents describe their reasons for becoming a foster home? What reasons do they give fore keeping on being foster parents? How do they comprehend their task and the fulfilling of it? The study was performed by utilizing qualitative interviews with five foster parents, four women and one man. In the analysis we used the theory of action as a theoretical perspective.

För närvarande läses elmätare av en gång per år, detta leder till att kunders elräkning baseras på ett schablonbaserat belopp. Enligt riksdagens proposition 2002/03:85 skall dock alla elkunder, senast fr.o.m. 1 juli 2009, faktureras efter faktisk elförbrukning varje månad. Detta har lett till en stor marknad för fjärravlästa elmätare som nu är ett måste för att kunna utföra den tätare avläsning som krävs. E.ON ES Sverige AB som är beställare av detta examensarbetet har specialiserat sig på att installera, underhålla och läsa av fjärravlästa elmätare åt nätägare.

Att vi människor överöses av kommersiella budskap från företag innebär att vi tvingas selektera vilka budskap vi uppfattar. Företags marknadsföring kan vi avskärma oss ifrån, men hur reagerar vi då vänner vill sälja produkter till oss? Syftet med studien är att undersöka om och i sådana fall hur vänskapsrelationer och affärsverksamheter påverkar varandra inom ett nätverksföretag, samt belysa dessa effekter. För att besvara syftet har kvalitativa intervjuer genomförts med återförsäljare inom ett av de största nätverksföretagen i Sverige. Studien visar att när återförsäljare integrerar vänskap och affärsverksamhet uppnås både positiva och negativa effekter.

This thesis presents my work at the company Fatshark AB in Stockholm. My supervisor Rikard Blomberg, who works as a chief technology officer at Fatshark and is one of the owners of the company, explained that they had experienced weaknesses in the methodology used when developing heads up displays (HUD) for their games. In the latest production, Lead  and Gold, the HUD had been redesigned a number of times, becoming an unnecessarily big expense due to the number of work hours invested. In modern software development, an iterative workflow is commonly encouraged. Despite this fact, the work efficiency could likely be increased by setting up guidelines as a help in the process of developing HUDs and reviewing the solutions.

This thesis examines the verification of the terms and conditions stated in contracts based on the Public Procurement Act. In March 2013 the Swedish state procurement commission released " Good Business - A Strategy for Sustainable Public Procurement " (SOU 2013:12), which found that the proportion of control and verification is relatively low. The thesis examine how verification is carried out and looks for an explanation to why verification is not more oftenly performed. To answer these questions two care studies, based on seven semi-structured interviews, is presented as the empirical material. Network theory has been used to analyse the empirical results, and aspects of commonly used theories such as contract management and "Markets and Hierarchies" by Williamson has also been taken into account.

The purpose of this essay is to investigate Swedish as a second language acquisition in a group of students with diverse culturul backgrounds. my intension is to find out if a dialogical posture in teaching with focus on the students earlier knowledge,experianses, thoughts and feelings, will contribute to a teaching enviroment where the students can express them selves and listen to each other. the teachers task is to help the students to explore their own thinking.According to the theoretical base of the essay, sucessfull second language asquisition occours in a meaningsfull context through dialogue and interaction between students and teacher as well as between student and student.I have used a qualitative method consisting in participating as a teacher in this group of second language learners during four lessons, observing, taking notes and writing diary. The teaching material used during the lessons was a book (fiction but based on a true story) and the dialogue in the group proceeded from the story we read together..

The aim of this paper was to describe hindering and facilitating factors in the transition from upper secondary school and employment for a person with Asperger?s syndrome. In the process we used general systems theory and made semi-structured interviews with five persons in the network of institutions and associations working with the individual. Our findings showed that the hindering and facilitating factors were basically the same depending of the environmental adjustments. The interviews highlighted the following factors: the recent general unemployment rate in Sweden, selfawareness of the individual and the surrounding environment?s knowledge of the individual?s impairment in relation to Asperger?s syndrome.

The final thesis named Tracking in Sensor Networks was created by the company Instrument control Sweden. The thesis work is to create a plug-in to an already developed software pro- gram, SkyView. Via the software program one should be able to control an IP-camera from AXIS, model 215 PTZ, with the appropriate protocol over a network.  An Application Programming Interface, API, was used to easily control the camera through SkyView. The interface is called VAPIX and is used to all cameras from AXIS.

The law firm industry has during the last years met new demanding conditions and one tool to handle these new conditions has been to implement a Knowledge Management system. Large investments have been made in these Knowledge Management systems but the implementations have met many challenges from within the organizations.With a multiple study, based on interviews with Knowledge Management Managers included in a Knowledge Management network, this thesis aims to study the challenges with Knowledge Management and the underlying causes. The result, based on McDermott's theories shows challenges within technical, personal, social and management areas where the law firm need to shift a focus from Information to Knowledge Management, create a culture of trust and integration and use the informal powerbase.The causes for these challenges are found in the base of Mintzbergs theories of Professional bureaucracy where the Knowledge Management is affected by strong self-regulated individualist, a divided organizational structure and industry conditions..

One task of school is to counteract traditional gender patterns. Literature is an actor which can affect people?s perceptions of what is feminine and what is masculine. It can therefore be worth looking at the works of fiction that are available for pupils in school. A book that is popular among children and adolescents is Twilight (2007).

The purpose of this study is to search and analyze different logics that operators use in the work of helping juvenile delinquents to break their criminal behavior. New institutional theory is used in this study to analyze the results. The study was conducted through qualitative interviews of six professionals in two municipalities which work with juvenile delinquency. There are two questions that we want to address in this study. The first one is what methods the social workers are using in two middle large municipalities to help youth to brake there criminal behavior.
