Utvärdering av en FPGA för rymdbruk

A new FPGA suitable for space applications has just reached the market. To investigate whether there are any possible flaws or limitations similar to those previously seen on FPGAs, an evaluation has to be done. This master thesis contains the evaluation of this new radhard FPGA with focus on possible design limitations and package related electrical phenomena.Areas evaluated: Ground-/VDD bounce, Cross talk, Rise time sensitivit, Power cycling, Power consumption, Place and route tool, Radiation hardnessThis report contains all steps in the evaluation. From method to measurements, comparisons, theory, results and conclusions. In the evaluation work, special effort has been made to develop designs that really stress the FPGA to find potential problems.

Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.

Kulturen bakom kulturen - En komparativ studie av kultursynens inverkan på tyska och svenska kulturpolitiska strukturer

This thesis aims to develop a theory in the under researched field of international comparative cultural policy studies. lt does so by combining theories from the fields of political scienceand cultural studies, researching how and to what extent the concepts of culture of different states have an impact on the way cultural policies are constructed.The thesis uses this theoretical development in order to research a specific problem, namely the perceived possibility that Swedish and German cultural structures are slowly converging. Two recent official policy documents from each country are the objects of study. Through comparative idea analysis and with Michiel S. D Vries theories on decentralization, the thesis explains the convergence between the countries by differing cultural views between them.

Elektroniska tidskrifter - var, när, hur och i så fall varför?

An increasing number of scholarly publishers are beginning to make their journals available electronically. At the same time there is a growing amount of exclusively electronic journals freely accessible on the Internet. These are facts that librarians have to take into consideration.This master's thesis aims to describe the electronic journal and its role in Swedish academic libraries. In a review of current literature about electronic journals, the authors discuss their strengths and weaknesses, and their impact on scholars, publishers and libraries. To investigate the situation in Sweden, a questionnaire was sent out to 43 academic libraries.Questions were raised about the selection and acquisition of electronic journals, access, technology and economy.The results show that almost half of the 35 responding libraries offer electronic journals to their users.

Design och konstruktionsförbättringar : En omkonstruktion av mockningsredskapet SverigeGrepen

This thesis will describe the redesign of the manure fork SverigeGrepen. The productis available for purchase in Scandinavia and and parts of the rest of Europe.The product is available in stores but the companys goal is to start distribute it overthe internet. A problem today with a purchase over the internet is that the costumerhas to pay a high shipping-fee due to the products unique form. The long handlecontributes to the high shipping-fee which makes it hard to attract costumers topurchase the product online. Deficiencies have been found at the manure forks basketand needs to be examined.

Sociala företag en av flera aktörer i det sociala välfärdsarbetets tjänst

Social enterprises make up one of the groups of participants that provide welfare services financed by public funding. The object of this study is to describe and analyze from a theoretical point of view which conditions, in what fields, by which division of responsibility and finally through what decisions these social enterprises are allocated a place in the market for social welfare services. The company that has been the object of study offers services in the field of social welfare and in employment. In the study a triangulation of qualitative methods has been used: studies of literature on the subject, recurrent interviews and observations and also reviews of documents. The results have been analyzed from theories on the space available on the market for social services, on social economy and on social capital in the form of strong, weak and bridging bonds.

Baumols kostnadssjuka och effektivitet i den svenska scenkonsten - En analys av Göteborgs stadsteater och Göteborgsoperan

Sedan teorin om Baumols kostnadssjuka lades fram i ?Performing Arts. The Economic Dilemma? (Baumol & Bowen, 1966) har flertalet internationella undersökningar berört ämnet, dock saknas omfattande studier i Sverige. Denna studie syftar till att undersöka Baumols kostnadssjuka i den svenska scenkonsten, där Göteborgs stadsteater och Göteborgsoperan väljs ut som representanter.

Elevers inställning till matematik : - en jämförande studie av elevers uppfattning av matematikämnet och matematikundervisningen

Based on earlier experiences of mathematics and mathematical learning, both as a student and as a teacher, I became more and more interested in how well the publicly accepted opinions about mathematics as an uninteresting, difficult and ?geeky? subject corresponded to reality. What do Swedish pupils really think about mathematics and is it possible to identify any differences in their attitudes based on the pupils? age?From this point of view the following questions were formulated:·What are pupils? attitudes towards mathematics in grades 3, 6 and 9 and how do they conceive their learning conditions?·Is it possible to detect any differences in the attitudes and preferences depending on the pupils? age?The result of this study compares well with previous studies done in this and overlapping fields and indicates that:·Younger pupils tend to have a better liking of mathematics but with increasing age that interest fades out.·Most pupils, without regard to age, consider mathematics to be one of the most important subjects, despite the fact that many pupils also find mathematics difficult and boring.·For pupils of all ages, the teacher is the most important factor in the learning process. Older students have more specific demands on the teacher for knowledge and pedagogical skills.·A high noise level, talking and disturbances in the classroom are the most bothering elements when it comes to learning mathematics.

Faktorer som bidrar till att kursmålen nås för elever med matematiksvårigheter

During my practice as a teacher trainee at an upper secondary school it became clear to me that many pupils had difficulties with mathematics. I was surprised to find that many pupils seemed to get stuck on the level of attainment for the senior level of the nine-year compulsory school. As I have not studied anything about difficulties in Mathematics during my training to become a qualified teacher, I would like to get to know more about this.After studying research done on this subject I made the following approach to the problem:? What fields regarding Mathematics do the pupils themselves find most difficult?? What factors have been contributory causes to these problems?? What are the factors that have helped pupils with difficulties in Mathematics to reach the goals for the syllabuses in Mathematics?The answers to my questionnaire and interviews resulted in the following conclusions:? Pupils find theory of equation and conversion of units as most difficult at senior level of the nine-year compulsory school.? Teaching should be done in special instruction groups to give the pupil the opportunity to develop his/her skills on an individual level.? Pupils find it hard to deal with all moments in Mathematics during the time given for each course.? The pace for teaching Mathematics is too high according to the pupils.? Pupils wish for instructions on a lower level.? There is often a lack of contact between teacher and pupil.? The teacher should use more time to help the pupil receive good self-confidence and increase the motivation for instructions in Mathematics..

Personlighetstyper och stressrespons hos djur ? med fokus på hund och häst

Animals living in captivity are often subjected to various kinds of stress. Individuals within species can respond differently to the same stressor depending on differences in coping style and physiology. Active and passive coping is a common way to describe different coping styles in animals and it is likely that these strategies have a high heritability. Individuals with an active coping style are characterized by an urge of control and a higher level of aggression than individuals with passive coping style, who in general are more flexible and respond to stress by immobilisation to a greater extent. The aim of this bachelor?s thesis is to investigate the presence of different coping styles and personality types in dogs (Canis lupus familiaris) and horses (Equus ferus caballus) and to find fields of application for this information.

Bibliotekskatalogens utveckling i Sverige från medeltid till nutid ? sedd ur ett institutionsteoretiskt perspektiv

This master?s thesis deals with the development of the Swedish library catalogue. The thesis primarily has two purposes. Firstly, it describes how the Swedish library catalogue has developed from its first appearance until today. As the Swedish library sector is very extensive the authors have chosen a few catalogues which they have studied more thoroughly.

Kantzonsvegetationens inverkan på dieten hos öring (Salmo trutta) i en skogsbäck

Effekterna på öringens (Salmo trutta) diet till följd av en avverkning av kantzonsvegetationen har undersökts i ett fältexperiment, där två av de potentiella effekterna av en skogsavverkning simulerades. Fokus låg på de två faktorerna ökad ljusinstrålning och minskat nedfall av terrestra evertebrater. Ökad ljusinstrålning har simulerats med hjälp av montage av lysrör och nedfall av terrestra evertebrater med hjälp av plasttält. Frågeställningarna rör andelen terrester föda i olika behandlingar och årstider, dietskillnader mellan äldre och yngre öringindivider, skillnader i mängden akvatisk föda vid ökad ljusinstrålning samt en taxonomisk översikt av dietens sammansättning. Signifikanta skillnader mellan behandlingarna fanns, där individerna i kontrollbehandlingen åt signifikant mer terrester föda än individer i tältbehandlingen och den kombinerade tält- och ljusbehandlingen.

Män som förskollärare - pedagog, pappa eller presumtiv pedofil?

The purpose of this thesis is to explore whether male kindergarten teachers perceive additional expectations from their surroundings (such as co-workers and parents). Furthermore, we aim to understand and explain how these expectations are related to gender norms and hierarchies in society, that is social constructions concerning what men and women should do and be like. In addition, the thesis aspire to understand and explain how these constructions relate to more specific social constructions about sexual molestations in kindergarten contexts and explore how these discourses influence male kindergarten teachers in their work including which strategies they use in order to cope with them.How do male kindergarten teachers perceive additional expectations from their surroundings?How do male kindergarten teachers perceive the effects and consequences of the social constructions about sexual molestations in kindergarten contexts? Do they use coping strategies in order to attend to the expectations projected on them, and if so, what kind of strategies? The thesis is based on a phenomenological approach and conducted through interviews with six male kindergarten teachers. The interviews were directed with an interview guide in hand while allowing for spontaneous input from the interviewee.
