This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

This study was conducted at Glimek AB, a company that has chosen to decentralize its central storage unit in order to increase production efficiencies. The purpose of the study was to identify the problems in the production cycle that lead to the decision to decentralize the central storage unit, as well as identifying what the decentralization entails. The effects of the decentralization have not been analyzed in the study, and consequently neither financial nor production disadvantages have been considered.Appropriate questions were formulated based on the chosen underlying theories, and were asked to selected individuals with relevant knowledge. The study is based on the information that was gathered from interviews with management as well as staff within the company. In addition, supporting information such as flowcharts, drawings, orders and decision support documents were supplied by the company.

This study is based on interviews with five unit managers working in the functional disabilities business. The purpose of this paper is to examine how these unit managers see their roles and their leadership, and to give the reader an insight into what it might entail to be a manager in social work. Theories applied are the role theory and three leadership theories. The previous research this study made ??use of affects ?leadership in social work" and "manager's role and leadership style."Being a unit manager of the functional disabilities business means having a so-called middle management position, which entails expectations being directed upon them from various avenues.

Our aim with this study is to explore socialworkers perception of what is a good treatment is and how to establish good relationship with their clients. We have decided to limit our study with social workers in Economic assistance and Abuse Units in social servises and explore if we can discern any differences between the units. We have chosen to use qualitative methods to achieve the aim of this study. We interviewed a total of seven social workers, of which three were from Abuse unit and four were from Economic assistance unit. One of the theoretical frame we have used is Goffmans (1970, 1974) theories about social interaction in which he explains the social encounter between social workers and clients.

Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.
