Automatic registration of dairy cows grazing behaviour on pasture
Information regarding cows grazing behaviour and time spent grazing can be of great interest to dairy farmers, since this information can indicate how well suited the pasture is to the cows. Feed intake at pasture is however challenging to measure. Automated systems for monitoring the behaviour of cows within dairy production have become increasingly important and relatively common. The aim of this study was to validate an activity measuring device (HOBO® G Logger Pendant Data Logger, USA), a triaxial accelerometer that registers the cow?s Head positions during grazing, in order to see if cows? grazing behaviour on pasture could be distinguished from their non grazing behaviour.
Vision Enhancement System : Vilken betydelse har displayplaceringen?
At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.
Beräkning av ASME-flänsar enligt EN-standard
In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Engreppsskördare med Head-Up Display
Arbetsbelastningen för föraren i en engreppsskördare är stor. Vid aptering måste föraren fokusera om blicken för att läsa av information från en Head-Down Display (HDD) samtidigt som föraren måste ha kontroll på kranspetsen vilket bidrar till arbetsbelastningen.Syftet med projektet var att undersöka om arbetsbelastningen i engreppsskördare reducerades med Head-Up Display (HUD) under aptering. Först testades fyra HUD-gränssnitt i en simulator, därefter omarbetades gränssnitten innan de slutligen testades i en engreppsskördare i fält. En HUD-demonstrator utvecklades för detta ändamål.Resultatet visade att arbetsbelastningen samt apteringstiderna minskade i simulatortestet med HUD jämfört med HDD. I fältstudien förblev arbetsbelastningen oförändrad men apteringstiderna minskade.Att arbetsbelastningen minskade med HUD jämfört med HDD kan bero på att HUD är bättre än HDD och/eller att konceptens gränssnitt är effektivare att arbeta med än Valmet Maxi gränssnittet.En HUD-demonstrator som fungerar under ljusstarka förhållanden och som tål påfrestningarna i en skördare borde utvecklas för vidare tester..

Bibliotekschefer och stress - En kvantitativ studie av arbetsrelaterade stressfaktorer i svenska folkbibliotek
This dissertation discusses head librarians in Swedish public libraries and the stress factors which affect them. The aim is to map out potential stress factors which head librarians come across in their day-to-day work. The purpose of the dissertation is to answer the following question: what stress factors affect library managers in Swedish public libraries? The dissertation was conducted through a literature study, informal interviews and a quantitative questionnaire. The results of the quantitative questionnaires show that the factor that produces the highest level of stress is having too many different tasks.
En bra Chef går hem : - en undersökning av Landstinget i Värmlands chefsbrev
Internal communication is very important for the success of an organization. The county council Landstinget i Värmland is a large organization with many managers on different positions. Every one of these managers gets an email every week, with the message that a new manager letter, called Chef, is published on the intranet. With my paper I am examining what the managers think of this letter, how they use it and if managers on different positions differ from each other in opinions about and use of the letter. I want to find out if there is a need of Chef as a part of the internal communication of Landstinget i Värmland.To answer these questions, I have chosen a quantitative method in the form of a questionnaire which is send to all the receivers of the manager letter.
Två nyladdade batterier och en morotskaka : - Konsten att motivera sig själv som chef
When we started this study we quickly saw that almost all the previous research that we find was focused and concentrated on the fact that the employees should be motivated. The research also presents a top-down perspective which means from the head to the employee. A Swedish newspaper wrote in an article that 1/3 of all Swedish heads can?t motivate their employers. A Swedish internet platform discusses this and says that heads need to be motivated to be able to motivate people around himself.
Informationsförmedlingen till Försäkringskassans handläggare
The main purpose of this master thesis is to study the information support by the head office of the Swedish social insurance office to its administrators. The thesis only focuses on information that concerns laws, regulations and instructions. The study is based on an interview with the head of the division of law at the social insurance head office and a questionnaire answered by administrators in four different counties. The purpose with the interview was to find out about the information strategy of the head office and in the questionnaire the administrators could describe their opinion of their information support. Our special interest was the information channels and how the administrators were able to absorb the essential information.
Den provocerande kroppen : En diskursanalytisk studie av konstkritiska texter som behandlar utställningarna Paul McCarthy Head Shop/Shop Head och Nationalmuseums Lust & Last
Syftet med denna studie är att utföra en kritisk diskursanalys av ett urval konstkritiska texter som behandlar utställningarna Paul McCarthy: Head Shop/Shop Head från 2006 och Nationalmuseums Lust & Last från 2011. Utställningarna exemplifierar det jag kallar för den provokativa konstens diskurs. Genom analyserna vill jag se hur ett urval kritiker mottagit utställningarna samt ge en bild av den provokativa konstens diskurs med dessa två utställningar som exempel..
Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :
Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse.
This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.
En imitation med original -En diskursanalys av kulturskapande över fältgränser
The purpose of this thesis is to discuss how agents create their culture outside of their ?own? fields.What does this way of creating a culture mean for groups already existing on the field? Who ownsthe power to construct their own subject positions? Through a discourse analysis, I analyse thesequestions through articles and interviews treating two cultural fields which I call ?The hip Berlin?and ?Swedish hip hop culture?. I argue that, depending on a persons priviliges, one owns the powernot only to construct subject positions of ones own, but also for persons with less privileges in theexisting hegonomy of society..
Där män är män? maskulina subjektspositioner i Michael Moorcocks fantasyromaner
The aim of this Masters thesis is to examine subject positions of masculinity in the fantasy novels by Michael Moorcock, spanning from the sixties to the present. Questions are: Which positions of masculinity dominate in four fantasy works by Michael Moorcock? How do these positions differ from each other or are there similarities? Do they strengthen or undermine the hegemonic masculinity? How do these positions of masculinity relate to historic configurations of masculinity? In order to find feasible answers to these questions I have used a theoretical and methodological approach rooted in the sociology of literature, mens studies and discourse analysis. Different masculinities are defined as subject positions. The hegemonic masculinity is defined as the image of masculinity that dominate and that every man has to relate to, in one way or another.
Smärtlindring hos kalv efter avhorning. En beteendestudie där effekten av meloxikam som postoperativ analgesi utvärderas :
In this study, 29 calves were dehorned by heat cauterisation at the age of 1 to 8 weeks. Before the procedure, the calves were given local anaesthetic but were not sedated. In connection with the dehorning, 14 calves were given the non-steroidal anti-inflammatory drug (NSAID) meloxicam and 15 calves were given placebo. During the following three days behavioural studies were performed to investigate if the different treatments had any effect on the calves´ postoperative behaviour.
Head shakes, head rubs, kicks and ear flicks were studied, as earlier studies have shown that an increase in these behavioural patterns suggests postoperative pain.
