The vision of this thesis was to create a concept that can be used as a base for amachine construction. The purpose of this project was to use different methods todevelop a concept that on the best way meets the sat up requirements. This projecthas been divided into three stages/parts; principle, primary and the final solutionstage.This thesis has been conducted in collaboration with Västkustägg AB. It is aconstruction project designed to construct a machine that will automatically putlabels on the egg packages. Västkust AB wanted to automate this process.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

The purpose of the study is to investigate the significance of organizing social- cooperative in relation to individual empowerment; and how this empowerment can be used to better the situation of others. Young surfers is a social- cooperativ that is run by cooperators with experience of substance abuse and criminality. The social- cooperativ is built on the premise that the cooperators are to set up and run a screen-printing shop where they will print t-shirts and sweatshirts. The purpose of this business is that the cooperators are given the opportunity to work and that youths with social problems such as substance abuse and criminality are given the opportunity to work-train. My study is comprised of a series of interviews and observations that I have conducted in relation to the cooperators of Young Surfers.

This report was written as a result of a Bachelor Degree Project at the School of Technology and Society at University of Skövde spring 2007, together with Jede AB in Mariestad. The report covers the development of a door to a coffee vending machine that is under construction, and will in a chronological order describe the project from ideas to final product.The project started with a rather extensive feasibility study that thru market research and user tests sorted out the opinions of potential customers, concerning today?s available assortment. Technical areas concerning materials and manufacturing methods were also scrutinized for the consideration of the possibilities of a future production.The next step was to constructively generate ideas and thoughts that later on could grow to be potential solutions. After several weeks of hard work and pieces of good advice and recommendations from the assigner, four comprehensive concepts were built up.

The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens. Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions. The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.

The background of this paper is the dual role that the social worker can have, of beeing both supportive and controlling in the meeting with clients. It is also about the power the social worker can have, how they handle the power in their profession and how they remain to it in the relationship with the client. The study is qualitative and built on interviews with eight social workers that work in different areas in the social services. We have chosen to see this dual role as if the social workers have to, in their daily work, handle the roles as one authority role and one supportive role towards the client.The purpose of this study is to understand how the dual role as the social worker has in the profession, as a helper and a authority, is expressed in the work and relationship with the client. We have turned this purpose into two questions: How do social workers with authority remain to the dual roles of the profession? How do the social workers describe and understand power?We don´t want to generalize in this study, we want to give an example of the social workers own experiences about the dual role.

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

The primary purpose of this essay is to study and describe what single adoptive mothers believe to be significant motives when considering adoption. This essay also describes how single adoptive mothers experience parenthood in relation to their expectations. The theoretical perspectives applied to analyse the empirical data are existentialism, the identity making process, and social constructionism. The method of this study is qualitative based on seven interviews. The material has been analysed by condensed meaning units and themes with a phenomenological approach.

The aim of the essay is to explore how so called ?safe spaces? are built, and the part that creativity can play in this construction. The essay also explores the duality of idea-based social work that at the same time strives to support vulnerable groups and strives to make social and political changes. The essay has its empirical base in the RFSL Ungdom project ?Tusen bilder, tusen ord? (A thousand pictures, a thousand words).

Danmarksplass is situated just outside the centre of the city of Bergen on the Norwegian west coast. It was built in the 1930´s as a result of an architecture competition won by the prominent Norwegian architect Ole Landmark. Danmarksplass was originally meant to function as a local square, but its location next to Fjösangerveien, a road that caters for most of the through traffic in the Bergen valley today and is part of one of the main European roads, E39, would prove it difficult for that idea to prevail. Along with the ever increasing car traffic, Danmarksplass has more and more become a very busy traffic junction. Nowadays the car is the sole ruler of Danmarksplass.

Logistic Culmination ? One or Two Sides of the Coin?An Observation From a Different Point of View Logistic culmination can be compared to a stretched rubber band. If combat units moves in direction away from the supplies the rubber band will gradually stretch. The rubber band will eventually burst and at that point the logistic culmination will be a fact. But if the rubber band was to be let go before bursting, it will instead be contracted.

Galna Glassen is a company that has a unique way of selling ice cream in Sweden. The idea is for the costumer to be able to compose their own favorite ice cream, partly by choosing the flavor of ice cream but also by picking the ingredients. The ingredients that can be chosen from are around twenty and can be everything from cookies to candy to berries. When the costumer has chosen their ice cream and ingredients they are mixed together on a cooled granite board.The company was very successful when it was founded in the summer of 2011 and decided to expand to other cities in Sweden. They also wanted to explore the profitability of a mobile sales unit that is intended for festivals and events.The thesis is meant to develop Galna Glassen?s mobile sales unit.

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.
