Viltbroar i Sverige. En jämförelsestudie på rörbroar av stål som alternativ till traditionella betongbroar vid uppförande av faunapassager
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.

Syntes och struktur i SAB förr och nu: En studie av avdelningen för språkvetenskap genom den första, den fjärde och den sjunde upplagan
The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.
Platt och jämlikt? : En fallstudie av Feministiskt Initiativ
The aim of this work is to define the party structure of Feministic Initiative (FI). We want to examine the structure of an organization that doesn?t start out with a hierarchical order. We further intend to examine the party?s leadership; whether or not it is equal, between the three spokespersons.We find it interesting as a topic from a democratic point of view as well as to see if a flat structure could work in practice.
Från planering till inlärning : En studie om processen från en lärares planering till vad eleven lärde sig
AbstractThe aim of this essay was to examine the process from the teachers plan to what the stundents actually learned in the history subject. Too respond to the aim, I have performed interviews with one teacher, four students and also observed one lesson. The interviews and observations have been analysed according to other writers works in this subject. The questions the essay starts out from is: What is the teachers plan for the lesson? How did the teacher and the students carry trough the lesson? Have the students achieved the teachers aim for the lesson? Thanks to the teachers plan for the lesson, how the teacher carried trough the lesson, and the teachers relation to the students, there was good conditions for learning.
BIM på Trafikverket : Förslag till en utvidgad investeringsprocess
2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.
Kommer boken? : uppsökande verksamhet för funktionshindrade på Uddevalla stadsbibliotek ? en organisationsstudie
The purpose of this Master Thesis is to investigate the quality of the library service at the City Library of Uddevalla. In particular this thesis will examine the quality of the library service to people who are disabled. This applies particularly to the service to people with reduced ability to move or to see, which also includes people with infirmities due to old age. We also have investigated how well the library itself is adapted to the disabled. In order to get more information about the library service to people who are disabled, we have studied literature on this subject and the Master Thesis contains a summary of those documents.

Bland "busiga småpojkar", "ett konstigt beteende" och "besvärliga kvinnor". : Föreställningar om adhd, schizofreni och borderline.
Abstract: The purpose with this study was to explore different peoples preconceived opinions of three psychiatric diagnoses; Attention Deficit Hyperactive Disorder (ADHD), schizophrenia and Borderline Personality Disorder (BPD). These designations are accompanied by a definite social stigma, which could have profound effects on a person diagnosed with either disorder. These designations carry the risk of excluding and labelling individuals and could provoke a feeling of abnormality and potentially segregate them from the Community. This study is a qualitative study of six individuals, (sample size equals six). The rationale behind the selection was to get a broad representation of different individuals? opinions.

Automatisk nivåreglering av strålkastare
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
?Men de används ju inte.? - en undersökning om distributionsstödda böcker från bibliotekariers synpunkt.
The purpose of this study is to investigate librarian?s opinions concerning literature with state supported distribution and how to mediate and market these in the library. The types of mediation and marketing that have been studied are positioning, labeling and oral mediation.The study is qualitative with interviews at seven main public libraries in central Sweden. The respondents of the study were responsible for the literature with state supported distribution within the library.The study is based on a theoretical frame of reference containing theories from Jofrid Karner Smidt, regarding librarian?s mediation in libraries, and François Colbert?s theory on marketing planning for arts and culture.The results of our study showed that librarians have both positive and negative opinions when it comes to the literature with state supported distribution.

Historieämnets vara eller icke vara : En kvalitativ studie av Historielärarnas förenings arbete för att stärka historieämnet i den svenska skolan.
Since 1820 there has been a continuous discussion about the contents of history courses and the current debate considering this school subject is no exception; it is as vital as ever. Both in educational policy and public debate the role of history as a school subject has been brought up for discussion.In this study the writer has chosen to study the politically independent interest organization HLF. The organization is a non profit association, which works for the consolidation of history in Swedish schools.The purpose of this study is to investigate how the organization HLF has received and met the ongoing debate on this issue. The writer has chosen to examine the strategies the organization has used in order to influence this school subject and if they have succeeded in doing this.To carry out this study the writer has made use of HLF´s annuals as well as Aktuellt om historia, which is a publication that the organization issues three or four times a year. The conclusion of this study is that HLF has little influence when it comes to the formulation of the education of history.
