Temperaturens, kadaverålderns och radiopulssekvensens betydelse för bildkvaliteten vid magnetresonanstomografi av tarsus hos häst
Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
Bibliotekskatalogers användarvänlighet : en usabilitystudie av Umeå Universitetsbiblioteks katalog Album
The purpose of this thesis is to examine the usability of the Umeå University library catalogue Album. The aim is to evaluate the catalogue in order to establish if there are any problems that could be solved by modifying the catalogue. The following questions are answered: How should a good catalogue be designed? Which problems are common when using a library catalogue? Is Album user friendly? Are there any problems that occur when using Album and how can the catalogue be changed to avoid the problems? To answer these questions I have performed a usability test in which five persons, all students, got to carry out twenty tasks in the catalogue and talk about what they were doing and thinking while doing the test. This method is a usability method called Think Aloud.
E-tjänstutveckling ur ett medborgarperspektiv : Att skapa beslutsunderlag baserat på medborgarärendens lämplighet för olika kommunikationskanaler
Citizens? interaction with governments is an area with unique implications for channel management. Governments need to take the citizens perspective into further consideration in order to be successful in delivering high-quality e-services. This paper aims to determine if a categorization of citizen-initiated contacts from a citizen-centric perspective can be a valuable basis for decisions regarding e-service development. The study consisted of three steps.
EKG-analys och presentation
Tolkningen av EKG är en viktig metod vid diagnostisering av onormala hjärttillstånd och kan användas i förebyggande syfte att upptäcka tidigare okända hjärtproblem. Att enkelt kunna mäta sitt EKG och få det analyserat och presenterat på ett pedagogiskt sätt utan att behöva rådfråga en läkare är något det finns ett konsumentbehov av.Denna rapport beskriver hur en EKG-signal behandlas med olika algoritmer och metoder i syfte att detektera hjärtslag och dess olika parametrar. Denna information används till att klassificera varje hjärtslag för sig och därmed avgöra om användaren har en normal eller onormal hjärtfunktion. För att nå dit har en mjukvaruprototyp utvecklats där algoritmerna implementerats. En enkätundersökning gjordes i syfte att undersöka hur utdata från mjukvaruprototypen skulle presenteras för en vanlig användare utan medicinsk utbildning.Sju filer med EKG-signaler från MIT-BIH Arrhythmia Database användes för testning av mjukvaruprototypen.
How to build a rein tension meter
A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.
Självupplevd livskvalitet hos barn och ungdomar med cerebral pares
Syftet med studien var att undersöka livskvaliteten hos barn och ungdomar med cerebral pares. 56 barn och ungdomar med cerebral pares i åldern 10-18 år med Gross Motor Function Classification system (GMFCS) tillhörighet I-III, som gick i grundskola, grundsärskola eller gymnasieskola och som erbjöds insatser från Skånes 11 olika barn- och ungdomshabiliteringar har undersökts via en enkät: Child Health Questionnaire (CHQ-87).CHQ-87 är ett självskattningsformulär bestående av 87 frågor, indelade i två huvudområden som tillsammans täcker individens fysiska och psykosociala hälsa. Enkäten skickades ut per brev under våren 2008. Totalt skickade 167 enkäter ut och 56 enkäter inkom besvarade.Resultatet visar ingen signifikant skillnad mellan den fysiska och den psykosociala hälsan. Skolsituationen och kamratrelationer upplevs positivt av flertalet som svarade och merparten svarar att de har det bra i sina familjer.
Folksonomi ? en förklaring i perspektiv av kunskapsorganisation
The aim of this master's thesis is to investigate and to explain the concept of folksonomy in the perspective of knowledge organisation. By creating a conceptual explanation and defining what folksonomy as a concept consists of, the intent is to establish a basis for evaluating folksonomy and to discuss what relevance folksonomy may have in the field of knowledge organisation. By applying a qualitative content analysis a review is performed on how folksonomy is perceived and discussed in a selection of articles written on the subject. Employing the theory of classification, subject indexing and bibliographic retrieval, folksonomy as a method for knowledge organisation is analysed. The practice of tagging in existing systems is also studied.
Europeiseringens inverkan på svensk deklarerad utrikespolitik
Abstract The purpose of this study is to examine if the Swedish policy of foreign affairs has been changed due to the Swedish enter as members in the European Union. The research method used for this essay has been a comparative case study between the Swedish and Norwegian declared policy of foreign affairs and it strives to answer the research question, which is if the Swedish declared policy of foreign affairs has been changed in character due to the Europeanization. The theoretical framework of this study consists of Europeanization as a comprehensive theoretical perspective. I order to answer the research question a classification schedule has been elaborated to examine the objectives of the Swedish and Norwegian declared policy of foreign affairs. The analytical method of this part has been a quantitative and qualitative approach.
PennTags: En kvantitativ empirisk studie av en read/write OPAC
The aim of this thesis is to study the phenomenon of read/write OPAC by looking at how students at Pennsylvania University use PennTags in order to influence document descriptions in the library catalogue. The main questions to be answered are to what extent PennTags is being used in different subject areas and what users contribute to document descriptions through tagging in different subject areas. Studying the posts created by a sample of PennTags users from a quantitative approach I try to find out if there is reason to believe that the activity of users and users? possibility to make meaningful contributions are dependent of the subject matter being dealt with in documents described, as anticipated by the theory of pace layering. I find that user interest in influencing the library catalogue through PennTags appears to be low in general, with exception for in the subject areas of the main classes Language and literature and Social sciences in Library of Congress Classification.
Pivot - en aktiv sittmöbel för kontorsmiljö
The purpose of this project was to invite a changed perception of active sitting, to introduce a more active way of sitting in office environments and destigmatize an active sitting posture such as straddling by giving active sitting products conscious aesthetics based on environment and positive associations. The goal with this project was an active sitting product for office environments with aesthetics considered encouraging to movement in a relaxed way, regardless of age and gender, and connect to materials and aesthetics related to activity, experience and recreation. Horseback riding, retro style surfing and skateboarding was an entry of investigation. The project was based on existing active sitting products, their function and production techniques. It was not a part of the project to investigate new models of sitting.
Portföljoptimering som alternativ till indexfonder : Hur skulle en fond konstruerad enligt portföljoptimeringsmodeller utvecklas i jämförelse med index?
This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.
Baklava och baguette : En studie av handelsutvecklingen mellan Turkiet och EU
In this study we examine trade patterns between Turkey and 13 member states of the European Union and how these have developed over the time period of 1983 ? 2006. To represent the industrial and agricultural goods included in the study we look at the United Nations Standard International Trade Classification (SITC). Following, we investigate internal differences in the EU by selecting four countries each to represent the Northern and Southern countries of the EU. Internal differences were studied in relation to the amount of trade occurring between Turkey and the Northern and Southern countries.
Ämnesordsåtervinning av skönlitteratur: En intervjuundersökning av bibliotekariers erfarenheter
The aim of this thesis is to investigate librarians? experiences and opinions about a system for fiction retrieval based on the subject headings list Att indexera skönlitteratur. I want to know if librarians experience that subject headings searches for fiction literature are a good working tool, if there according to librarians are other resources and means that makes fiction available and searchable, and how they estimate the possibility of non-professionals to use subject headings for fiction retrieval. Six librarians at public libraries in Göteborg where interviewed. The interviews dealt with their work with fiction literature, their experiences of subject headings as a fiction retrieval tool, and with their contacts with patrons.

Aim
The aim of this essay is to problematize how students with special needs are represented in the quality assurance documents of the school. The writer intends to point out how the ways in which the language used to describe students informs governing processes.
Effekten av Valutarisk på Bilateral Handel
This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.
