NATO:s luftkrig i Kosovo utifrån Wardens teorier
John A. Warden III is one the most mentioned air power theoretic of his time.He has written a number of theories concerning air power and the best way to use this to win wars.The author of this paper gives a short resume of what he consider are the central thoughts in John Warden´s theories. These thoughts result in four factors; Enemy as a system, centre of gravity, parallel attack/concentration and finally air superiority. These factors are then being used to inves-tigate if NATO used Wardens theories during the Kosovo war in 1999.The reason for the author to choose the Kosovo war specifically is due to the fact that NATO during the war only used air power as an instrument to get Serbia´s president Milosevic to the negotiation table but also the fact that this would turn out to be quite a challenge for NATO.The conclusion is that out of the four factors only one is traceable throughout the entire operation, and that is air superiority. Regarding the other three factors they can only be found in parts of the operation..
Förbättring av dockning mellan lastvagn och autoklav
At present Getinge can offer a new generation of trolleys that they produced in 2011. The trolley used to Getinge various autoclaves and has the primary task to help the user/sterilization personnel to transport shelves or baskets, with or without cargo, from a packing table to the autoclave. The purpose of this thesis has been to develop a primary solution how the docking process between Getinge trolleys and autoclaves can be improved. The work has in most part followed Fredy Olsson principle and primary construction method. The work has included product research, study visit and development of a requirements specification, to satisfy Getinge, their clients and circumvention products requirements.
Guld i Sverige - Från urtid till nutid
The Earth and everything else in the universe was created in the Big Bang around 14 billion years ago. A point with tremendous density and mass began to expand and more and more atoms began to form. From the first and lightest like hydrogen and helium to heavier atoms such as iron and eventually gold. The formation of the Earth occurred about 4.6 billion years ago and so the first gold atoms were concentrated only here. It is however believed that much later in Earth's history an extra supply of gold occurred thanks to massive meteorite bombardments.

Strategi för IKT i skolan ? att integrera teknik i ett komplex sammanhang : Mätbart, jämlikt, statusfritt
Today there are many studies that have shown positive results in the treatment of ICT at an early age. The focus of the studies vary, and they target everything from the actual implementation of teaching resources in ICT, to student performance with ICT support. Regardless of the amount of studies on the subject, there is no precise strategy for how to implement, working with ICT, integrate ICT in different subjects, utilizing the hardware and software that is or how it will eventually respond to new technologies. This work will there by focusing on trying to develop a basis for further research and hopefully in the future to develop an ICT strategy at a national level.In order to provide a basis, a comparison was made of ten different schools. The schools were entered into a table showing the similarities and differences .
Massundanträngning i samband med pålning i lera
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Lika bolag leka bäst - En studie om betydelsen av likhet vid sammanslagningar av bolag
This study addresses the issue of mergers between consulting firms. Previous research has shown that there are specific factors that determine the outcome of a merger and that success is more likely if companies are more similar. The purpose of the study is therefore to define relevant factors and understand when resemblance matter and under what conditions disparity may cause problems. Furthermore, the aim of the study is to find a pattern of which factors are more important in a successful merger. The problem of the study is addressed through a qualitative research approach and is conducted on six different mergers.

Nytt ventilationssystem till djurstallar :
There is two dairy farms in Sweden with ability to be opened on both long sides, one outside
Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results
or not enough literature about natural ventilation and especially on this kind of air inlet, makes
my tests very interesting not only on Alnarp, but among other companies.
I would like to find out if there is any air movements direct on the cows, how high/low
temperature, air humidity, light intensity and noise standard inside the barn. Does
Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could
this system become the new dairy barn instead of the conventional barns in Sweden?
I am going to focus on the animals environment, after all they are the one who is going to
spend the most of the time in the barn.
I used five electrical loggers distributed inside the barn to measure the temperature and one of
the loggers measured the air humidity, every 15th minute. One logger were placed on the
outside which measured both temperature and air humidity.
BORDTENNISSPELARES MÅLSÄTTNINGSPREFERENSER BEROENDE PÅ MÅLINRIKTNING
SammanfattningSyftet med studien var att studera skillnader i vilka mål bordtennisspelare använder sig av beroende på målinriktning. I studien deltog 103 bordtennisspelare (60 män och 43 kvinnor) tävlandes i division ett till tre. Metoden som användes i studien var en kvantitativ undersökning och bestod av enkäterna Collegiate Goal Setting in Sport Questionnaire (Weinberg, Burton, Yukelson, Weigand, 1993) och Task and Ego Orientation in Sport Questionnaire (Duda & Nicholls, 1992; ref i Duda, 1998). Resultatet i studien visade flera signifikanta skillnader mellan bordtennisspelarna med högre resultatinriktning och bordtennisspelare med en lägre resultatinriktning när det gäller uppfattning om målsättning. Resultatet visade exempelvis att bordtennisspelarna med högre resultatinriktning oftare satte resultatmål och prestationsmål jämfört med bordtennisspelare med en lägre resultatinriktning.
Nej, inte rita. Låna!: 3-4-åriga barns informationsbeteende på folkbibliotekets barnavdelning
The aim of this study was to examine how children in ages 3 to 4 use the public library with the research questions: What does children?s, in ages between 3 and 4, information behavior look like when they visit a public library in leisure time with a parent? What is the nature of interaction between child and parent, child and the staff of the library, and between child and other visitors? What is the function of the cultural tools in relation to the children?s information behavior? The theoretical frame of reference consisted of Lev Vygotsky?s ?the zone of proximal development? and Roger Säljö?s theory about using cultural tools. To answer the questions I have observed 4 children together with their mothers and siblings at a public library. From the result of the observations I found that every child had their own information behavior. Two of the children only used one kind of cultural tool ? books.

Termisk Vattenpump
This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.
Shape from Silhouette Scanner
The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.
