This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

This essay contains material of how the competence maintenance works on a chosen company and how a web based tool developed for its use can help companies with competence insur-ance. As competence maintenance is a major factor to have a long term profit it´s necessary to be aware of the company?s future needs in the competence sector. This essay describes the company?s competence maintenance occupation needs taken from internal documents; it also identifies the need for competence maintenance and presents multiple areas of possible im-provements.

Under vår tid på lärarutbildningen har vi tagit del av en omfattande mängd litteratur som behandlar hur lärare ska väcka och upprätthålla elevernas drivkraft och intresse för skolarbetet. Med hänvisning till detta uppstod frågan om vad som driverlärarnaoch vad som får dem att känna tillfredsställelse i sitt yrke. Syftet med denna uppsats blev av den anledningen att belysa de faktorer som är mest bidragande till att hämma eller främja lärares motivation och arbetstillfredsställelse. För att finna svaren utfördes en intervjustudie med kvalitativ ansats. Resultatet av intervjuerna diskuterades utifrån HerzbergsThe two factor theory.

Denna studie undersöker hur människor engagerar sig med och på elektroniska sociala nätverk (OSN). Syftet var att undersöka på vilket sätt som personligheten påverkar hur vi använder OSN. Data från sextio deltagare insamlades genom ett webb-baserat formulär baserat på femfaktormodellen (?Big Five?) och instrumentet Big Five Inventory. Deltagarnas aktivitet på Facebook uppskattades genom frågor utformade för denna studie.

The purpose of this study is to increase understanding of how parents of children in need of special support have experienced their interaction with the pre-school. Our three main areas of interest were to investigate how several parents experienced their contact with the pre-school, if there were any experienced factors that had played a part in the contact with the pre-school and if we could conclude anything about how the curriculum had been followed in these cases, with assistance of the parents? experiences.Our study is qualitative and we chose to interview six parents. We both participated in all of the interviews. The theoretical base of this study is rooted in the phenomenological theory and we also used the framework factor theory to complement our analysis.One of our conclusions was that the parents expressed so many different experiences that we decide not to try compare them in general.

Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas. In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.

This bachelor thesis in European studies examines the perceived effects ofEuropeanization among officers, soldiers and seamen in the Swedish Armed Forces(SAF) through the use of semi-structured respondent interviews. The study focuses onchange in rules, values, identity and organizational changes.The study shows the most important parts of what is believed to be the biggestfactors behind the major change in the SAF during the last 20 years. The biggestfactors are shown to be the fall of the Warsaw pact and the increasing influence ofNATO in Europe. Interviews show that staff within the SAF has difficultiesseparating change coming from the EU and the above-mentioned factors, partially dueto the fact that most members of the European union are also part of NATO. Although in some areas, such as the completion of the Nordic Battlegroup, EU has played an important role and presents itself as a major factor in the ongoing change of the SAF..

The purpose of this qualitative study is to investigate how some teachers make use of the results of the national tests in mathematics to plan their teaching. The questions are how they plan their teaching in mathematics and if they use the results of the national tests to compare with their own teaching.   Five teachers in mathematics has been interviewed. I have used unstructured interviews with open-ended questions, and I have been able to ask follow-up questions based on their answers. The analysis of the survey is made from a systems theory approach.  The result of the survey shows that teachers make use of student performance to look at their own teaching of the current group of students. However, there is not enough time to rehearse and repair the deficiencies discovered in the national tests, which for some is perceived as a stress factor.

The commercial real estate market makes up a large part of Sweden's property portfolio, as well as other open, free markets in the real estate market it is regulated by supply and demand. There are several factors that affect the supply and demand in the commercial real estate market, for instance the price, type of real estate and the condition of the real estate. In order to achieve success in the commercial real estate market it requires that real estate agents have a certain expertise and flexibility in their thinking to adapt commercial real estates to supply and demand. Active investors on the commercial real estate market are for instance private real estate agents, their knowledge and experience will help increase the value of commercial real estate in the long run. In order to provide the market flexibility in its real estate portfolio, vacancy is a factor that can be used.

Syftet med föreliggande studie är att undersöka om möjliga själv är relaterade till personlighet och känsla av sammanhang samt huruvida kön och ålder påverkar dessa relationer. Studien genomfördes på kadetter genom en enkätundersökning. Enkäten bestod av bakgrunds frågor, yrkesrelaterade möjliga själv (The Possible Selves Statements Test), personlighet (The Five Factor Personality Inventory) och känsla av sammanhang (KASAM). Resultatet visar att kluster (K-means) av personlighetsprofiler inte skiljer sig signifikant åt vad gäller möjliga själv, däremot uppvisades skillnader mellan personlighetsprofilerna vad gäller känslor och förväntningar kring möjliga själv. Liknande resultat erhölls avseende relationen mellan KASAM och möjliga själv.

The aim of this master thesis is to examine which criteria are generally used to guide pub­lic librarians in their acquisitions' decision. The study went ahead in France, principally at La Bibliotheque municipale de Lyon. It also includes a view of some special library services in the social field.Twenty persons were interviewed and an attempt was made to divide their answers into three sections: acquisition routines and criteria for media purchase, how to receive the library visi­tors and their influence on the acquisitions, and, finally, the librarians' own opinions on the matter. One important question was whether censorship is applied and in that case, would it be a deliberately way of acting or rather a spontaneous reaction, more or less unconscious.Censorship in real or manifested through a self-preservative reaction turned out to be a factor closely dependant on the library's financial situation. Many librarians affirmed they would find useful some kind of a written practical library acquisition policy..

Society and technology develop together in interaction processes. Because of the development of information technology, the Industrial society has been left behind in favor of a society where information is the key production factor, i.e. the Information society. In the Information society, social functions and processes are organized in networks. These networks integrate geographically separate markets to parts of a complex global economic system.

Gastric ulcer is a common disease among pigs in the whole world where an intensiveproduction occurs. It is mainly the upper region, the nonglandular region of the stomach thatis affected. Gastric ulceration is a disease with several risk factors. The factor that seems tohave the largest impact on the development of gastric ulceration is a small particle size of thefeed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a largeherd-to-herd variation.
