Utveckling av dynamiska farthinder

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.

Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

Realistisk interaktiv miljö

Spel och simulatorer som skall avspegla existerande miljöer måste för spelaren vara trovärdiga vad gäller landskap, arkitektur, attribut och ljussättning. För att kunna bygga och implementera sådan realistiska och trovärdiga miljöer krävs ett grundligt förarbete med referensmaterial, skissarbete och tester. Under 10 veckor har jag gjort mitt examensarbete tillsammans med Försvarshögskolan och Data Ductus AB på ett projekt som vi kallar för Foreign Ground. Det har resulterat i en djupgående förstudie och research som ska bli en bra grund för att skapa en demonstrator till ett utbildningsspel. Spelet är tänkt att användas för träning av FN-soldater som är på väg till Liberia på utlandsmission.

Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.

Död ved och förekomsten av två mossor som indikerar skoglig kontinuitet

Studiens syfte är att undersöka arterna Buxbaumia viridis och Nowellia curvifolia för att kunna förutse var man hittar dessa signalarter. Detta gjordes genom att död liggande ved undersöktes i Ycke naturreservat samt en närliggande brukas skog, Östergötlands län.Resultaten visar att faktorerna som är avgörande för B. virids är markkontakt och nedbrytningsklass. B. viridis föredrar att växa på lågor i de högre nedbrytningsklasserna (4-7) och med stor andel markkontakt, över 80 %.

Framtidens forntid : Geofysisk och geokemisk prospektering av järnåldersgården RAÄ 108, Fresta sn, Uppland

This paper deals with archaeological prospection of an Iron Age farm site in Toland, Fresta parish, Uppland County in Sweden. The purpose of the paper has been to see whether the geophysical methods applied (GPR & EM-38) could produce useful results that could motivate its use in similar surveys in the future. Geochemistry has been used for the purpose of identifying possible activity areas on the site. The results have shown that it is possible with a GPR survey to identify postholes originating from the Migration Period longhouse at the site. The combining of several methods have been important for the identification and interpretation of several areas of interest..

Boktips 2.0 : En kvalitativ studie om elevers delaktighet i skapandet av boktipsvideor på en biblioteksblogg

The aim of this study was to, through a qualitative method, investigate students? participation in a specific library blog to find out what motivate them to create and share digital book recommendations through videos. It also intended to describe the students? own views of their participation.We conducted interviews with eight students in the ages 12 and 13, who all had similar experiences regarding the blog creation but diverse attitudes concerning the blog production and intentions to participate.The results showed that the strongest motivating forces behind the students' participation in the blog creation was that they enjoyed the making of the videos and also because they wanted to inspire others to read more and create resembling blogs..

Utveckling av reglersystem till quadrokopter

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

IUP och interkulturellt ledarskap : individualitet med syfte att inkludera?

The aim of this essey is to examine how teachers´ work with individual development plans (IDP) can contribute to an intercultural leadership and inclusion. The interwied teacherss ay that IDP forces them to reflect critically on their thinking on aspects as learning methods, gender and ethnicity. It makes them listen to -and think - in new and more including ways to adapt to each pupils individual possibilities to achieve the curriculum standards within the common area. That requires lots of resources like extra teachers and new material.An active reflection can make ethnocentrism develop into intercultural competence. That is a listening, critical and diversified thinking prepared to deconstruct and create new ways of thinking in relation to different pupils and situations.

 Användandet av fältarbetsförmågan :  En jämförelse av fältarbetsförmågan i Sverige och i Afghanistan

Denna uppsats skrivs som examensarbete under sista terminen på officersprogrammet på Försvarshögskolan. Uppsatsens syfte har varit att undersöka om det finns någon skillnad i hur fältarbetsförmågan används i en nationell insats i Sverige och i en internationell insats i Afghanistan och om det finns några slutsatser att dra om eventuell skillnad. Genomgående i uppsatsen har de fyra inriktningarna; fältarbeten för rörlighet, fördröjandefältarbeten, fältarbeten för överlevnad och övriga fältarbeten används för att förklara fältarbetsförmågan. De resultat som visade sig efter jämförelsen var att det finns ett litet behov av broresurser och fördröjande fältarbeten i Afghanistan jämfört med Sverige. De dragna slutsatserna är att fältarbetsförmågans storlek i Afghanistan är beroende av den totala insatsens storlek.

Distriktssköterskors informationsanvändning - en studie av informationsanvändning i förhållande till arbetsuppgifters komplexitet

This study is an attempt to examine the information needs and use in everyday tasks inthe work environment of community health nurses. The purpose of this paper is double toexamine the information need and use of the community health nurses and to test and validatea method and a theory for the studying of information need and use in workers everydaytasks adapted from Byström and Järvelin (1995). Most of the data were collected throughdiaries kept by the informants in close relationship to the problem situations and were analysedqualitatively. Furthermore a literature survey was made in nursing infomatics and informationscience and it showed that there is no absolute common ground between the disciplinesin the way they use the information concept.The theory and method were validated in a broad outline and were very useful in the study ofcommunity health nurses' information needs and use. The study also shows that the contextof community health nurses plays an important role in the nurses information behaviour..

Wheat : an analysis of variables determining the Swedish price of wheat

Increasing volatility and less political intervention from the CAP in the market price of wheat is making it more difficult than in the past for Swedish farmers to determine the price at which they should sell their wheat. In the past, the Swedish farmer-owned company Lantmännen has traditionally set a guideline price for Swedish wheat every year to which farmers could adapt, but ceased doing so last year. Therefore this study sought to identify the parameters on which the price of wheat is dependent on by using a reduced form model. The perspective adopted was that of farmers. The model proved able to identify the main factors determining the annual price fluctuations in wheat, with all variables included having an impact on the wheat price, except export quantity in the previous year.

Retention of stumps on wet ground at stump-harvest and its effects on saproxylic insects

Low stumps represent on their own up to 80% of the dead wood remaining on clear cuts and therefore supply suitable habitat for saproxylic insects i.e. insects depending on dead wood for their survival. Recent stump harvesting activities threaten this substrate of ecological importance and increase the anthropogenic negative impacts on these species. Because of technical and environmental reasons (nutrient leakage, erosion) guidelines for stump harvesting recommend to retain stumps standing in wet parts of clear cuts. However, stumps in wet positions might not be a satisfactory substrate for saproxylic insects and therefore might not be as much used as stumps in dry positions.
