Kalvhyddans utformning : påverkan på kalvens hälsa och komfort

This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.

En utvärdering av två pearl growing-metoder i ISI Web of Science

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

En jämförelse mellan TLS och UAV-fotogrammetri : Inmätning av hårdgjorda ytor

At present day there are several different methods for measuring of paved surfaces.The most common methods today are measuring with a total station, the GlobalNavigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently thedevelopment of unmanned aerial vehicles, known as drones, has increasedexponentially and today there are several ways of using drones for measuring surfacesby photographing and laser scanning.This thesis contains a comparison between the methods terrestrial laser scanning(TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements havebeen applied on two different test surfaces, one of asphalt and one of gravel. Thepurpose of the comparison is to investigate whether the airborne photogrammetry isequivalent accurate in its height levels as the terrestrial laser scanning. For thecomparison to be more extensive, these two methods have not only been comparedin precision but also in the areas of ease of use and economy.The precision was analyzed by comparing the height levels in randomly placed controlpoints on the test surfaces.

Utveckling av Materialförsörjning : En studie av Sandvik Coromants försörjning av stål

This report is a master thesis performed by Adam Lundin at the company Sandvik Coromants production facility in Gimo. The work started in January 2013 and went on for the duration of 20 weeks, which is equivalent to 30 hp. The project was executed at the department GVR10. The scope of the project was to create a base for improvements in the purchasing process of direct material to the production. The background to the project was that the centralized purchasing department has gone through changes and decision was taken to decentralize the purchasing of direct material to Gimo.

Den kontrollerade tekniken : En studie om de exklusiva Plymouthbrödernas förhållande till samtida teknik

The purpose of this thesis is to examine the Swedish Plymouth brethren?s relation to contemporary technology. What types of technology are considered acceptable and where do they draw the line? Due to the brethren?s separation from the parts of the world they believe leads people away from God, such as the entertainment industry, immoralities etc., they reject use of television and radio. These two are viewed as uncontrolled types of technology since the user does not have control of its contents.

Trötthet och fördomar : en studie i diskriminering av överviktiga vid mental trötthet

Syftet med den här studien var att undersöka om mental trötthet leder till ökad diskriminering av överviktiga. Genom att använda en dual process-modell, inleddes undersökningen med en bedömningsuppgift som deltagarna fick utföra i labbmiljö. Vid ett senare tillfälle fick var och en ombesörja att de genomförde ett implicit associationstest (IAT), följt av en explicit graderingsfråga, där deltagarna uppskattade en eventuell skillnad i normal- kontra överviktigas mentala prestation. Syftet med dessa tester var att ta reda på om diskriminering mot överviktiga existerade inom gruppen i sin helhet på såväl implicit som explicit nivå. Hälften av gruppen hade genomgått en kraftig mental trötthetsbelastning före bedömningsuppgiften, med avsikt att se om bias mot överviktiga ökade vid mental trötthet.

Stödhjul för CSR : Ett ramverk för styrning av CSR

Syfte: Syftet med denna studie är att analysera hur framgångsrika CSR-användande företag verksamma i Sverige har utformat CSR-arbetet. Utifrån denna information ska ett ramverk skapas innehållande styrverktyg och styrtekniker för att underlätta företags arbete med att styra CSR-insatser.Metod: Studien bygger på fem intervjustudier som är genomförda på fem framgångsrika företag verksamma i Sverige. Den teoretiska referensramen är framtagen genom akademiska tidsskrifter och böcker. Den empiriska datan är insamlad genom semi-strukturerade intervjuer genomförda på plats och genom telefon.Slutsats och rekommendationer: Resultatet av denna studie visar att den främsta anledningen för de undersökta företagen att arbeta med Corporate Social Responsibility bygger på ekonomiska fördelar. Intressentstyrning är den främsta faktorn för att lyckas med arbetet med Corporate Social Responsibility.

Shape from Silhouette Scanner

The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

Framtagning av förbättringsförslag för SNCR-system

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

En jämförelse av beteende mellan vävande hästar och två icke vävande hästar under liknande förhållanden :

Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable. Seven weaving horses were included in the study.

Oljudens musik : En revolution i kompositionsteknik?

Noise music is created around sounds not often welcome in a musical context. Since the birth of electronic music in the 1950s a new perspective on composing has emerged. In electronic music, sounds and their timbre are as much important as melody, harmony and rhythm. This composing perspective is not often observed. Therefore I have examined a musical genre that stretches the boundaries of what we consider music, sound, noise, beautiful and terrible.

Den sanna kyrkans röst : Självförståelse och reformsträvanden inom Svenska Kyrkoförbundet 1911-1917

The purpose of this study was to gain greater knowledge of how preschool teachers and children using an experimental- and activity box in biology. To find this out, I have used the participant observation method and semi-structured interviews since my study is qualitative. The result of the work led to a greater understanding of the biologybox. It was shown that preschool teachers' involvement is very important for children and that the biologybox contained good and inspiring materials. Although educators desired that there was more material to choose from as well as the usage time of the biologybox should be longer than 3 weeks..
