This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

System Andersson AB is a company located in Jönköping that works with developing computer systems for the mechanical engineering industry. As of today, when this report is written, the company is working on the development of a new Manufacturing Planning and Control (MPC) system. This new system aims to create not only a user friendly interface but also a modern, stylish interface. To achieve this, the company has decided to work with a, for them, new application framework; Windows Presentation Foundation (WPF).System Andersson is well known for developing systems for different kinds of touch screens, this project is no exception. For this new user interface the company wishes to implement different types of Drag&Drop functionality.

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

The aim of the study is to learn more about the way preschool teachers work with Information and Communication Technology(ICT). More specifically, this study aims to explore how preschool teachers describe their experience of ICT, the conditions and opportunities to work with ICT, and their own knowledge and competence in the use of digital tools with preschool children. The research method consists of interviews with preschool teachers and observations at five municipal preschools in Stockholm as well as an analysis of the relevant passages in the Curriculum for the Preschool and the Curriculum of Stockholm city. This study shows that there seems to be great variation in the amount of ICT tools present in preschools. Preschool teachers expect a lot from ICT, and the improvements that it can make on their work.

Pet rabbits are increasing in popularity and the owners want the same treatment for them as they would want for a dog or a cat. However, the knowledge among clinical staff about these small animals is not always up to date. The aim of this paper is to highlight the needs of the pet rabbit and how these can be met regarding veterinary nursing. Pet rabbits are different from dogs and cats in several ways and their needs as patients differ as well. Rabbits are herbivorous prey animals. To avoid predators, they are very reluctant to show any sign of weakness for as long as they can.

The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.

This report is focusing upon relining from a client?s point of view. Potential buyers are given a presentation of the different methods available today together with a general briefing describing the process. An important part of this report are the interviews that took place with already established customers. Property owners, managers, pipe cleaners, and project managers whom all been in contact with relining have answered the questions given along with their own thoughts and have also given recommendations of other persons to talk to.

The supermarkets are taking more and more market shares for potted plants the last years, and a greater part is bought without prior planning. Signals from several European countries, for example Denmark and UK, indicate that potted plants with added value have become more and more popular and the added value is based on present trends. The meaning of added value in this thesis is fancy pots, packaging, pins or arrangements. Potted plants with added value sold in supermarkets offer the consumer the advantage of getting a ?ready product? quick and easy.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

This thesis presents the work of developing and testing a programming tool specially designed for children. The purpose of this tool is to make children capable of creating visual simulations and games that consist of actors interacting in a virtual world. The name of the programming tool is Behavior Cards, which comes from the fact that actors are programmed by giving them cards representing different kinds of behaviors. Behaviors are to some extent pre-programmed and can include general events specifying how the actors should act in different situations, in contrast to specifying every possible situation that can occur. The idea is that Behavior Cards should be easier to use than a more traditional text based programming tool, but it should also be expressive within the domain of visual games.

For many individuals gambling gives an opportunity for relaxation and social relations. The positive effects of gambling are for most individual?s considerable more than the negative effects. Even if gambling gives positive effects there is individuals that cannot control there gambling and therefore develop an addiction which disturb there life situation and health. The aim of this study was to describe which personal characteristics distinguish people with a pathological gambling and which psychological, physical and social consequences this pathological gambling causes for the individual.

When a municipality is about to realize an IT investment, e.g. an economy system, theywill need to do procurement according to the laws of procurements. To perform suchprocurement takes time and energy from the everyday work at the municipalities, andtherefore they want to make a quick and efficient procurement. Unfortunately it showsthat municipalities do not always make an assessment that is sufficient enough for theirneeds, which can result in an inefficient system in a longer perspective. Municipalitiesthink more often about the hard values such as costs of the investments, and not alwaysas much when it comes to the soft values, like the user-friendliness.

The purpose of this work is to develop and test a design process where quick decisions and model building has a prominent role. The goal is to develop a number of products and build prototypes to be shown during the Carl Malmsten Furniture Studies spring exhibition 2012. I?m also writing a report describing my work.To reach my goal I have each day during the first phase conducted a short research and found a concept based on that days name day. Then I have continued in the workshop and worked with three-dimensional models.

Complete tumour regression is the optimal outcome of cancer therapies. There are however types of tumours that naturally regress. Most of these are benign, dermatological and have an early onset in life. This literature study aims to elucidate the mechanisms behind spontaneous tumour regression. In Libechov Melanoblastoma-Bearing minipigs, an animal-model specifically bred to develop malignant melanoma, the tumours usually involute within three months.
