The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

Mergers and Acuisitions are becoming increasingly common. This can be explained with the fact that the competition is increasing. Therefore many companies are forced to join other markets. This thesis inquires into the process of Mergers and Acqusitions when one company buys another company. The main focus is set on how three different banks handle the process of Mergers and Acqusitions and what results this leads to. These are: Kaupthing Bank, Nordea and Citibank.

Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.

The most common preventive and treatment service for children in child welfare services in Sweden is the contact family program. The number of children who are involved in the program has steadily increased. Usually it is a single mother who apply for or is offered this service. The aim with a contact family is that the parent should get respite and that the child should have its network enlarged and sometimes get a male role model.The purpose of this study was to look into how children´s perspective was considered in the contact family process. I have studied the process in order to see how it works and to see to what extent children is participating.

Due to stress, the workplace is a setting where actions of health promotion are of great importance in the perspective of public health. Stress is caused by heavy workload, low control of organizing their tasks and lack of support from colleagues and supervisors. This can lead to cardiovascular disease, depression and insomnia. Due to the health problems that this causes, it is important to examine how senior immigration offices perceive their psychosocial work environment.The aim of this thesis is to examine how the senior immigration offices at the Migration Board perceive their psychosocial work environment. The study is based on a qualitative approach with deductive content analysis and the data has therefore been collected through interviewing six people based on a semi-structured interview guide.The result has shown that the senior immigration offices are pleased with their work environment and that their workload is constantly changing.

The purpose of this study was to examine what participants in the third phase (fas 3) of the Swedish unemployment program, Jobb- och utvecklingsgarantin, think about their situation, what they think about the program and if they feel stigmatized due to their unemployment. The data for the study was collected at one of the organizers of the program, which provides an introduction program for the participants. A qualitative method was used and the data was collected through six semi-structured interviews. The results were analyzed using Antonovskys theory of Sense of Coherence (SOC). The conclusions of the study were that the participants felt support from the staff at the organizer.

Delaktigheten på den öppna arbetsmarknaden är låg för personer med psykisk funktionsnedsättning. Metoden Supported employment (SE) har visat sig vara framgångsrik i att hjälpa denna målgrupp att nå, få och behålla ett arbete på den reguljära arbetsmarknaden. Fokus har i forskning riktats mot metodens effektivitet men denna studie inriktar sig på arbetskonsulentens stöd inom SE och syftet i studien är att utforska vad dennes stöd betyder för deltagaren i metoden. Kvalitativa intervjuer har genomförts med tre deltagare och en gruppintervju med tre arbetskonsulenter. Det skräddarsydda, det instrumentella och det emotionella stödet samverkar och leder till empowerment för två deltagare, som har nått en praktikplats där de trivs och kommer till sin rätt.

A pilot-study was used to investigate, types of assistance, assessed needs, outcomes and effects of special-needs assistance given to a subsample of compulsory school pupils in an effort to develop an evaluation strategy for identifying educational impacts of specific special-needs inputs.  Preliminary results indicate a tendency for postive outcomes for most pupils in the pilot group (n = 11) but also that many pupils have residual difficulties.  Pupils with residual difficulties mostly required special education asssitance with Maths, English or Swedish.  More pupils also needed support with behavioral difficulties.  More research and an expanding knowledge base is required in order to effectively evaluate outcomes of teacher support.  Schools need help in devising different methods of assistance and particularly for pupils with behavioral difficulties..

Overall aim of this master?s thesis is to describe and identify perceived barriers in Swedish businesses within solar energy field and analyze, based on four theoretical viewpoints, how these barriers can be handled. In other words how can the barriers be overcome or eliminated to better succeed in the commercialization process? The method applied is qualitative in which data has been collected through phone interviews originated from seven Cleantech businesses which operate within solar energy. Furthermore this thesis has a descriptive- and an explorative purpose.

With the help of large amount of archive material I have examined how Gustavsberg in Värmdö were affected by the great labor migration in Gustavsberg porcelain factory during the period 1869-1924. I have chosen to investigate how the municipality dealt with the poverty relief issue out of the labour immigration perspective. To my surprise I found out that Värmdö was not responsible for Gustavsberg in the poverty issue. The workers belonged to the factory, which had a relatively well-developed system of poverty relief in place. This is not to say that the workers received any support from the factory to any great extent.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

If Swedish companies are to compete with companies in low-cost countries they have to achieve a more efficient production. The purpose of Total Productivity Maintenance (TPM) is to increase the company's profitability by increasing the productivity. TPM is a method that involves all employees and aims to prevent failures in order to increase the availability of existing equipment.The aim of this paper is to evaluate the implementation process of TPM and give recommendations for the further implementation process. The conclusion and the analysis are based on a case study done at a production department at ABB Cewe-Controls facilities in Nyköping. The case study consists mainly of qualitative data from participation observations, surveys and interviews.Commitment of the management is a key factor in the implementation process of TPM.
