Grävlingar : En studie om grävlingar i fångenskap, deras naturliga beteenden och fysiologi

I det här arbetet presenteras en studie från ett projekt som ägde rum i Kolmården djurpark sommaren och hösten år 2003. Projektet bygger på ett uppdrag från jordbruksdepartementet. Det handlade om huruvida grävlingar i fångenskap reagerar i olika stressande situationer. För att kunna undersöka detta har grävlingarnas naturliga beteende studerats under fyra perioder från juni till september samma år. Det som studerats under perioden är grävlingarnas olika beteenden, lokationen i grävlingshägnet samt fysiologiska parametrar så som hjärtfrekvens och kroppstemperatur hos grävlingarna.

Nyhetsgrafikens utveckling

This bachelor thesis examines and discusses the question: "How can graphics for newscasts be adapted to follow technological developments in various media and increase its informative quality?" The work was performed on Swedish Television's own graphic department, SVT design in order to examine how news graphics need to be developed to follow the technological changes in media. The production resulted in a news graphics concept divided into three parts. Two of the sections show examples of how graphics can be adapted according to platform and the third section shows examples of news graphics that are produced at SVT Design by me. The bachelor thesis focuses on the development of technology in the media and examines areas such as interactive solutions, news graphics and the traditional television media..

Flodkräftans biologi och status i fyra sjöar på Ulvöarna :

Flodkräftan har minskat i antal efter att kräftpesten införts via signalkräftor till svenska sjöar och vattendrag. Inplantering av signalkräftor har medfört svårigheter för flodkräftsbestånd att återhämta sig då signalkräftan bär kräftpesten, men inte själva påverkas i större utsträckning. Förutom sjukdomar påverkas flodkräftors populationsstorlek också av predation. Om man bortser från pesten är det svårt att fastställa orsaken till populationsminskningen i sjöarna då många faktorer är inblandade. Syftet med detta examensarbete är att genomföra en litteraturstudie och att fastställa förekomst av flodkräfta i fyra sjöar i Västernorrlands län. I litteraturdelen behandlas bla.

Didaktiska implikationer i lärares samhällsuppdrag : Uppfattningar om demokrati och biologiskt ämnesstoff hos blivande lärare

In today?s school in Sweden the assignment of community encompasses mediated values and education of democracy as well of single subject matters. What does it mean then, that teachers have a certain kind of idea of democracy, and what implications may biology have for the assignment of community? In upper secondary school there are quite many courses in biology with a national curriculum, and findings show that students of teaching perceive or think of biology as helping to promote the dual-purpose of teaching. In this study, the author of the paper has interviewed four future teachers of upper secondary school with biology as one of their main subjects.

The part of AQ production that?s been investigated is the manufacturing of ATM-machines, where the costumer is Banqit. This company is a rater small company with about 4 % of the world market of ATM-machines.In order to achieve the aim of the report extensive interviews have been carried out with employees at AQ.

Organisatoriska grundvärderingar: Riktmärke eller tomma ord? - en studie om ledarskap och värderingar

Syftet med denna explorativa studie har varit att skapa en bild av chefens upplevelse gällande organisationens grundvärderingar och dess betydelse i dennes ledarskap, genom att undersöka hur de resonerar kring värderingar i relation till sitt arbete, organisatoriska värderingars funktion och det värderingsarbete som bedrivs. Åtta semistrukturerade intervjuer genomfördes med chefer på olika organisatoriska nivåer inom en produktionsenhet på ett företag inom kemi och läkemedelsbranschen. Studien har en kvalitativ och hermeneutisk forskningsansats och data bearbetades genom tematisk analys. Studien visar på att cheferna upplever organisationens grundvärderingar som generella och allmänmänskliga, och de anser att det är främst genom sitt handlande som de förmedlar dessa till medarbetarna. Gällande frågan vilken funktion grundvärderingarna fyller i deras ledarskap är cheferna motstridiga i sina svar, både individuellt och om man jämför de intervjuade med varandra.

Grafisk utvecklingsplattform för signalbehandling - Design och implementation

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter

Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.
