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.

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.

This study has been performed at a smaller high school and with its industry students, the high school is located in a small industrial community. The purpose of my study has been to find out what students think about their work with the project work, what they think has been positive and negative, how their motivation is influenced by the work on the project and if the work has been affected by factors outside the school world.The interviews have been carried out like normal conversation with open questions. The students who participated in the study comes from the school where I did my internship. The selection was done by asking all students from a specific course, those who were positive to participate are also the ones I have chosen to interview. My main study results, in summary, described as the students, once they were inside their work were positive to the project work and felt motivated in their work. Negative experiences, for the students which attend a practical program, has mainly been economic, as the school does not provide any financial support.

Within the field of welfare research, few people take into account both the aspect of gender and class. Thetraditional class-oriented research has a one-dimensional perspective on gender and the feminist welfare researchrarely carry out large comparative studies. A multi-dimensional perspective on the construction ofgender and class would benefit from both the feminist and class welfare-oriented research, and contribute toincreasing the knowledge about the individual's experience and attitudes to work and work time. The aim ofthis paper is to examine the correlation of the intersectional relationship between sex / gender position andclass position with the attitudes and motives for working time reduction. Especially in, (1) the value in work,and (2) the attitude to a high number of working hours, as well as (3) its combined effect on the conflict betweenwork and family.

This paper examines how to use different kinds of source material for building surveys. The studyexamines how to use legends, construction archaeological surveys and Ground Penetrating Radar(GPR) as source material, and use them against each other to ensure the reliability they have.As a starting point I used Gräfsnäs castle ruin in Alingsås, Sweden, as an example. Gräfsnäs castlewas probably built in the Middle Ages and was rebuilt through the ages until it became a ruin in thelate 1800s. The castle ruin is today Alingsås most visited attraction.The investigation has focused on three areas which are located in the very ruin; rescue tunnels, thecellar vault and the treasure.There are legends that describe how the castle lord of Gräfsnäs fled an attack of the Danes in 1612 ina rescue tunnel which ended at the beach. At the construction archaeological surveys carried out in1935-36 they found a sewer in the courtyard that was once served as rescue tunnel and ended in themoat.

The aim for this study was to find out what strategies women use to not react against inequality and sexist prejudice. In the study I used a critical realistic approach through, primary, the social ontology presented by Margaret S. Archer. The study focus on both the women?s construction of femininity and their construction of masculinity and what directions it constitutes for the women?s social orientation.

The aim of the study is to investigate the relationship between text and picture in two works by Sven Nordqvist, with the focus on how the action is propelled. The two works are compared in order to bring out any differences in the relationship and what significance this can have for the interpretation. The study also considers the theory of conceptual worlds to examine how the books can promote pupils? literary understanding. The method of analysis is based on Rhedin?s (2001) theoretical concepts and elements of Nikolajeva?s (2000) terminology.

This thesis is ordered by Peab Sweden AB Regional Jönköping and concerns of warranty inspections.The intention is to work out a basis, which show the most common complaints is the warranty inspections, and make a small analysis on what causes them to be. The report also presents possible solutions to prevent the occurrence of defects. It also covers the issue of how the client looks at Peabs way to overcome the objections of warranty inspections. The report has the following issues:?What are the most common errors observed during the warranty inspection??What are the causes of complaints??What can be done to reduce the number of complaints??How the customer thinks that the complaints be addressed?Twenty-five Guarantee survey records from the projects Peab has done in recent years has been the starting point for the investigation.

The shooting sport is one of the most widespread sports in the world and it isbeing practice in most countries. Based on their own experiences, in competition -and hobby shooting, the client M4Solutions found a demand and need for ashooting target that is manufactured in Sweden.The purpose of the project has been to develop, with the help of Marcus Walldén,two shooting targets from idea to finished product. These two shooting targets,Plate Rack Target and Dueling Tree, would each be equipped with a mechanicalresetting system but will in the future have the ability to be provided with anelectronic resetting system.The project from the client was divided into two theses. One of these two, writtenby Marcus Walldén, focused on the tripod parts and the overall design work forboth Plate Rack Target and Dueling Tree. The thesis that is presented in thisreport have focused on resetting systems, the design of protective plates and otherperipherals for both shooting targets.This work has primarily been in CAD environment where design, constructionand development has been given free rein.

The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.

This Master of Science thesis was a part of Pharmadule Emtungas project to construct a mobile automated cell for welding of carbon steel pipe (Heating, Ventilation and Sanitation). Pharmadule Emtunga is using a modular building concept for building pharmaceutical factories. The modules contain these pipes. The goal of the thesis was to present concepts for technical solutions regarding welding methods and fixtures for the cell. Conceptual models for the cell were made with aid of CAD software.

With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.

A systematic quality work is essential for anyone working in preschool, school,kindergarten and adult education to give children and students an equal education.Skollagen (2010:800) indicates that quality work should be focused on the nationalgoals of education. According to Skolverkets allmänna råd med kommentarer omsystematiskt kvalitetsarbete - för skolväsendet (2012) is the work to develop quality acontinuous process. Everyone's involvement and participation is therefore essential.Systematic quality work means to systematically and continuously monitor theactivities, analyze performance against national targets and based on that plan anddevelop. Although the work has been driven outside governmental policy documentssince 1997 shows, among others, Skolinspektionens audits of municipalities andschools that there is major deficiencies in the obligation to conduct a systematicquality work. It appears that more than half of the surveyed schools had deficienciesin its system quality work.This is the starting position this study takes on to and through literature review,document studies and interviews of principals is the subject problematized.

The purpose of this study was to enlighten the views of male social work students on; the social work profession, social work status and their career options. Also, the study aimed at getting these students angles of approach on the fact that they, being men, are a minority group within the profession of social work. Some of the main questions were: Why does not social work as a profession seem to attract men? What about the status of the profession of social work? What were the thoughts of male social work students about this? What advantages or disadvantages did they recognise, being a minority in the profession? The method used in this study was doing separate interviews. All of the interviewed students were convinced that they had a better chance of getting a job.

Det har blivit allt dyrare att bygga i Sverige, den svenska byggnadsindustrin har halkat efter övrig producerande industri och byggföretagen måste börja tänka i nya banor om de ska klara de nya utmaningarna. Lean-tänkande har länge nyttjats inom den tillverkande industrin och byggföretag har på senare år börjat snegla på dessa koncept i syfte att öka sin produktivitet. Problemet är att byggindustrin inte har homogena produktionsmiljöer och därmed inte kan använda samma lean-koncept som exempelvis bilindustrin. Därför har ett nytt koncept som kallas Lean construction utvecklats som bygger på ett antal principer från traditionella produktionssynsätt (Koskela, 2000). Konceptet är relativt nytt och forskningen inom området har främst fokuserat på lösningar på specifika problem istället för att skapa förståelse för konceptets helhet.
