There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their Designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.

The landscape architect is similar to the moviemaker in that they both want to mediate an experience with their creations. The landscape architect Designs playgrounds and the moviemaker makes movies for children, but how does the relationship between children and nature look like in the landscape formed by the movie maker?s fantasy? The purpose with this thesis is to study how the relationship between child and nature is depicted in a movie as a medium, by analysing ?My neighbour Totoro?, a Japanese animated movie from 1988 by Hayao Miyazaki. The analysis consists of two combined analyses, Experiential Landscape Analysis and Gordon Cullen?s Serial Vision, both of which analyse the relationship between a human being and her environment as well as the emotional changes that occur as she moves in it.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

Jag har i mitt projekt jobbat med mönsterformgivning och produktion av vävda möbeltyger, digitaltryckta tapeter- och textilier för en fiktiv hemmiljö. Mina designbeslut grundar sig på en fiktiv karaktär, Mr Chester Jester, hans estetiska preferenser och behov i samrådan med mina egna. Arbetets resultat är en gestaltning av världen han lever i, komprimerad till ett hemma hos reportage på gränsen mellan verklighet och illusion. Jag har jobbat med dubbelhet och speglingar - av mönster, av rummet, av tekniker och mig själv. Jag har undersökt illusionens verklighet och verklighetens illusion.My bachelor project is a work of pattern design and production of woven upholstery fabrics, digital prints on textile materials and wallpaper, made for a fictional home environment.

Polaris Eyewear is one of the world's leading companies in innovative eyeweardesign. My assignment has been to, in collaboration with them, expand their range with a pair of children's glasses, while maintaining the innovative character they are so known for.The problem with childrens eyewear today is that most of the time the glasses tries to mimic the adult eyewear and the ?childish? type of designing is spared. From an ergonomic point of view, a child's nose is smaller than an adults and therefore needs a different type of shape and nosebridge. In addition, children have softer ears, which means that they need a different type of shaftend as well.

AimThe purpose of this study is to, from a perspective of a PE teacher, look at how teachers of physical education in elementary school Designs and assesses the teaching of swimming. The issues underlying the study are as follows:Which elements are included in the swimming education and how do teachers work with these operations?What does the PE teachers classify as swimming ability and what do teachers experience as obstacles for the students development of swimming ability?How do the PE teachers interpret the knowledge requirement in Lgr 11?MethodThe study is based on six interviews of qualitative nature, with PE teachers from various municipalities in the region of Mälardalen.ResultsThe result yielded by the study is that the swimming classes can take different forms depending on whom the teacher is. Common to all the teachers in the study is that they teach emergency management and lifesaving. When it later comes to teaching how to swim and practice, the teachers who teach in the younger age groups work more concentrated and continuously with swimming, while the teachers who work with the older age groups just checks whether students can swim or not.

AbstractThe aim of the present study was to investigate what kind of factors contributed to motivate a group of nurses at a nursing home in western Sweden to to perform their work. Furthermore, the authors wanted to investigate whether the staff nurses felt that the leader helped to increase or reduce the perceived motivation to perform such work, and the way in which staff nurses perceived their relationship to the leader. The study is based on Herzberg's (1959) two-factor theory, Hackman and Oldham's (1980) work Designs theory and Leader-member exchange (LMX) theory, and those theories are the basis of the study's structure. The study was of a qualitative property, interviews were conducted with seven nurses and was structured, the questions concerned their subjective experience of motivating factors in their everyday work. The results of this study demonstrated that respondents experienced confirmation, the meaningfulness of the work, work colleagues, beneficiaries of care and residents' families as contributing factors to motivate them in their daily work.

This essay studies the relationship between politicians and municipal chief officers from the point of view of the bureaucracy and its role in democracy and the substance of the chief position. I conducted interviews and observations with politicians and senior officials from the local public administration in Bromölla. The roles of the chief officer and politicians have certain common characteristics which makes it difficult to separate them. Senior officials working full time in contrast to part time politicians give them an advantage in the political process. Budget cut backs both enhance the role of politicians and chief officers in the administrative organisation.

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

When the Eolshällproject was completed for the first time, a great deal of moisturedamage was discovered. Therefore the structure completion was removed andreinstalled. The project was originally planned to cost a total of 126 million SEK, but thefinal costs landed on 271 million SEK. What caused this failure? Were the Designs poor,was the technology used too advanced, or was the project not managed properly?Based on the Eolshällproject, theses will be presented about what may have caused themoisture damage.

Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new Designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.
