Kvalitetskontroll av trafikmätningssystem ? En studie om noggrannheten hos induktiv slinga, slang, KomFram, video och radar i olika trafikmiljöer
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.
Den ensamma flatan och glitterbögen : En kvalitativ studie av hbtq-personers porträttering i tre olika kvinnomagasin
The aim of this studie centers on how lgbt (lesbian, gay, bisexual, transgender) are portrayed in women?s magazines. The magazines we have chosen to analyze are FRIDA, VeckoRevyn and amelia, which all three have different target groups. We have, with the assistance of the rhetorical and semiotic analysis methods, assessed 18 articles with their associated photographs. These methods are part of the qualitative analysis model and are used in order to study less empirical data with more depth.
Anstaltspersonals erfarenheter och påverkan av hot och våld på arbetet : en kvalitativ studie
The aim of this paper was to describe the phenomenon of threats and violence within a Swedish penal institution. The study was thematized according to the three main research questions. These were as follows; The threats and violence prison staff have experienced in their workplace (I) how these experiences affected them in their work performances (II) and in their private life (III). By a qualitative design, in-depth interviews were carried out with four persons who are, or formerly have been, gainfully employed at a penal institution. Concepts from the theory of symbolic interactionism and a theory of human action have been used in the analysing process of this paper.
Tekniska möjligheter för artificiell spridning av renlav :
Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are of crucial importance to reindeers and reindeer husbandry, especially in the winter when reindeers primarily feed on different lichen species (Cladina spp. and Cetraria spp.).
En studie av Uppsala stads värmeö
The urban heat island is an area restricted to a city center where the temperatureis higher than its surrounding environment. The greatest temperature difference isfound at night when the weather is calm and the sky is clear of clouds. There are twomajor causes behind this phenomena and the first one is the use of energy forheating of houses. The heat leaks through the walls of the buildings and warms upthe surrounding mass of air. The second one is the use of building material whichstore the suns radiation on daytime and releases the heat during night.
Fria och öppna programvaror inom kommunal verksamhet : Vägen mot öppna standarder?
This report deals with the attitudes within municipalities of open source software and open standards and if open source software may be an option to gain open standards. The aim has been to find out if open source software and open standards would be able to solve the lock-in problems that municipalities have against proprietary software. The study is conducted as an exploratory, inductive and qualitative study with depth interviews of subjectively selected informants as data collection method. A literature review has also been implemented by the relevant books and articles. Some economic determinants of municipalities to make use of open source software have not been considered in this study.
Vederlagsgrundande mätning med skördare
This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district.
The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.
Athena - En intelligent och flexibel säkerhetslösning för transportbranschen
The project team has chosen to carry out the project itself. This is to be able to work more flexibly in the product development process and not be guided by some guidelines.Every day, we read in the media about a new truck burglary. The problem has become so common that we do not even notice it in the media. Each year the theft of 1 billion of Sweden and the entire 82 billion in Europe in 2008. This is an increase of 10 billion by 2007.
Belöningssystem i heterogena organisationer -I teori och praktik
The purpose of this master thesis is to, with the strategies of the organization and the preferences of the co-workers in mind, explore how reward systems can be designed in heterogeneous organizations. This is done by interviewing store managers and sales personnel in a heterogeneous organization. The frame of reference deals with theoretical approaches on reward systems and is divided in the following sections, individual or group based, differentiated or not differentiated rewards systems and goals, measurements and rewards. These sections are highlighted from the following aspects, equity, implementation possibilities and finally environment. The theoretical discussion ends in the conclusion that heterogeneous organizations should have several different reward systems, but not if a restructuring process is in progress or the system becomes too costly.
Tillvänjning av labradorer att skritta och trava på löpband :
The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.
Jobbcoachning- en skjuts i karriären eller en lindring i misären - En kvalitativ studie av jobbcoachningens roll på arbetsmarknaden
This paper examines job coaching on the Swedish labour market. The study uses trygghetsråden, which are organizations established by an agreement from the labour and employer side, as a starting point for the study. In addition, the study examines the phenomenon from the perspective of the job coaches themselves and the coaches clients. The study concludes that job coaching is defined by the coach and the client's common goal of finding a suitable match for the client on the labour market. The job coach helps the client reach the goal of an appropriate job by making him or her aware of his or her competences and preferences.
Val av tidpunkt för markberedning vid naturlig föryngring under skärm av Pinus sylvestris i Svealand : Timing of scarification when using natural regeneration in seed tree stands of Pinus sylvestris in Central Sweden
This thesis is built on a field study that was carried out in two seed-tree stands near by Götbrunna in Uppland, Sweden. The aim was to examine if scarification carried out in spring time could generate a more dense seedling establishment when using natural generation, than scarification carried out in autumn. It was also investigated whether there were differences in mortality the first season between the two plot-types. Plots were established block-wise with 50 blocks (pairs) on each site. The spring scarification was made with a hoe during 22-23 of April.
Konstens dilemma : Hur ser politikerna på konstnärernas försörjning?
Politicians attract their voters by promising more jobs and investment in education, health and social care. Against this background, I wonder how the situation of artists will be affected by the followingquestions:? What political views on the artist's position in society appeared in propositions of Socialdemokraterna and Moderaterna?? In what way did these propositions influence the conditions of artists?? How have the artists of Värmland been affected by different (Socialdemokraterna and Moderaterna) cultural policies? With my investigation I find out more about the artists' conditions on a national level, but I also investigate the situation in Värmland. By examining policy proposals and reports, I learn more about the issues. I also conduct a survey and three in-depth interviews to obtain opinions from various sources.The respondents are the cultural departments of Värmland and representatives from cultural organizations.What is clear from my research is that politicians differ on some issues, especially those relating to commercialism and artist salaries.

Hedersrelaterat våld : En studie om socialarbetares förståelse av hedersrelaterat våld
After the honor killings of Fadime and Pela, an extensively discussion started in the media, debating honor-related violence and oppression. This debate also made us, the authours of this paper, to pay attention to the problem. As a professional in social work, there are several good points to be made by having an in-depth knowledge in the field, both to discover individuals exposed to honor-related violence and to be able to protect them. The study was conducted by four qualitative interviews with professionals in social work with a professional experience of honor-related problems. Through the interviews, the social worker's view of honor problems emerged.
