Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.

This study is about children that have been forced to flee to another country, due to conflict, poverty or natural disasters, without their families. They are known as unaccompanied refugee children. The aim of the study is to, by focusing on individual children's feelings and experiences of being forced to flee create greater knowledge and understanding of what is hidden behind some of the statistic of migration.To answer the aim of the study, I used the following research questions: How is a child affected by being forced to leave home and to flee to a foreign country? How does an unaccompanied refugee child perceive the exodus? How do the unaccompanied refugee children handle their situation during the flight and at arrival in Sweden?The study is based on a qualitative method and consists in semi-structured interviews with five unaccompanied refugee children aged 17 to 21. The theoretical framework is based on three theoretical concepts; refugee crisis, identity and coping.The study results show that these children are a very vulnerable group, who were forced to be exposed to several losses and traumas.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

I ett samhälle där tiden blir en allt mer avgörande faktor ökar konsumenternas efterfrågan på tidsbesparande konsumtion. E-handel erbjuder konsumenter besparandet av tid och bekvämlighet genom att det är möjligt att göra inköp, när som helst och var som helst. När företag väljer att tillämpa e-handel innebär det att de inte längre kan möta kunden öga mot öga. Vid hemparty, som är en form av direkthandel, sker försäljningen i direktkontakt med kunden. Försäljningen äger rum i kundens hem tillsammans med dennes vänner och bekanta.

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

The purpose of this essay was to examine how professional social workers work with follow up foster home placements. The study was based on qualitative interviews with ten professional social workers from different municipalities in Skåne in an attempt to answer the following questions:* What routines exist for the follow-up work with foster care?* What factors have an impact on how the follow-up is formed in the particular case?* How can the follow-up affect outcomes of the placement?* In what way could the work with follow-up foster home placements develop?The theories we chose to analyze our material from was the ecology of human development formed by Urie Bronfenbrenner and the theory of civil courage formed by Lennart Lundquist. The interviews were semi-structural which gave the respondents a chance to talk in a free way about the questions we presented.The result of the study showed that there is a difference in the way social workers form the follow-up work of foster care. The greatest difference is in whom the social workers include in their follow-up.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..
