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.

Presentations of Oriental people as subordinated the West and their ideals was one way for Europeans to expand and keep control over their colonies in Africa during the nineteenth- and twentieth centuries. France and Great Britain controlled their colonies in different ways which has led to diverse legacies. Today, tourism is a source of revenue for former colonies, such as Tunisia and Kenya, and tourism also helps to spread knowledge and images of distant countries. A guidebook is one way that knowledge of other countries and people are spread to travelers. During history, images of distant people were based on a colonial discourse in which the west was seen as superior; but is that still the case? The purpose of this paper was to analyze how Tunisia and Kenya are presented in the Lonely Planet guide to Tunisia and the Lonely Planet guide to Kenya to investigate if they are constructed through a colonial discourse, and to see if there are any dissimilarities on how they are presented.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

Background: Of those who start companies, only about 30 % are women. Women's companies also often have both fewer employees and lower turnover. Several efforts are therefore being made to try to influence and encourage more women to start businesses and to get them to expand. Two of these ventures are special network for women and about women entrepreneurs as role models, something that also the theories believe is very important for a more egalitarian business. While entrepreneurship is encouraged for growth in the community, it also has a male character, something that needs to be considered.Purpose: As both the EU and the Swedish government through measures such as Tillväxtverket, is investing large sums to promote networking and role models, we intended to analyze the importance of networking and role models for entrepreneurial women.

This thesis examines how Swedish newspaper media problematize surveillance. This is done by analysing the media reports from two major surveillance events: the debate in 2008 about the legislation concerning the expansion of the rights of Försvarets Radioanstalt to monitor internet and telephone traffic crossing the Swedish borders, and the revealing of an ethnically based index including over 4000 individuals created by the Swedish police. The thesis sets out to expand the knowledge about media?s role as a interpreting source of information concerning how people understand and relate to surveillance (Barnard-Wills, 2011; Carlsson, 2009; Greenberg & Hier, 2009). The thesis attempts to answer the question whether Swedish media problematizations regarding the abovementioned surveillance events correlates with the most common theories of surveillance critique.

The purpose of this master thesis is to describe and analyse the development of the library history in the municipality of Karlsborg. This is done with a comparison to the library development in Sweden as a whole and in particular to the cities of Lidköping and Halmstad. I have worked according to the following questions: 1. How did the libraries develop before the municipality took over? 2.

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and  to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.

During the later parts of the 20th century there occurred several changes to the Swedish public sector. These changes aimed to effectivize and decentralize the governance model in the public sector. One of these changes was the municipalization of the school system, put forward and proposed by the social democratic government in the late 1980s and early 1990s. This study aims to examine and compare that times different parliamentary parties' opinions on the municipalization of the school system. The source material consists of government bills, and in direct relation to the municipalization of the school system.

The main purpose of this study is to show how narrative can be understood as cultural practice, how it can be said to function both internally and externally, and to ask questions about how the narrating subject, through the organizing of narrative, positions it self and mediates between the different discoursive contexts of which it is a part. This is done by an analisys of how six swedish soldiers tells the tale of how they came to choose a military carrer and why they have served or want to serve in peace-keeping missions abroad. The source material is primarily collected through unstructured interviews with theese soldiers, but also through textual analysis of a soldier blog. Theoretically the study draws on a combination of the discourse theory of Michel Foucault, narrative theory, Richard Jenkins theory of the internal-external dialectic of identifikation and intersectionality to construct a framework that allows the narratives to be deconstructed and understood as discoursive products of both the military contexts as such and the larger cultrual context that surrounds it. The conclusions of this study suggests that the organizing of soldier narratives are a complex and multifaceted process, in which the soliders must balance between the ideals, values and norms of the military context while also taking into account how society at large views and interprets the practices and forms of military life.

My problem comes out of the bigger question ?why the Catholic church is featured in horror films whenever a religious organization is in one?? I have detected in the horror films that I've seen that when a religious organization is in a horror movie it's the Catholic church that gets to act as church and religion. I have chosen the following problem: How is the Catholic church presented in the horror movies The Exorcist and The Rite, and how can one understand these presentations from a role theoretic perspective?Since role theory has it's background in the world of the theater with it's actors and roles, it came naturally to use role theory, and specifically Goffmans dramatic model. I've used this model in a film analysis of the movies.

The public libraries in Sweden has an obligation to serve all of its citizens, but despite of this they often fail to include their LGBTQ-patrons. Since the year of 2008 RFSL (the Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights) have arranged a specially designed certification-process based on normcritical criterias that a chosen institution should fulfill to make their work more inclusive for LGBTQ-people. Sollentuna is the first municipal in Sweden to certificate all of their libraries. This study aims to examine what the certification have meant for the public library in Sollentuna and how a normcritical view can contribute to include LGBTQ-patrons at the library. As a method we used a qualitative interview-study to get a full picture of the certification-process and its influence on the public library of Sollentuna.

Communication of sustainable development has become an increasingly important part of organisation?s corporate branding. Consumers demand more transparency from businesses and want to know more about how they work with these issues. An important part of how internal communication can be used to reach organisational success involves organisation?s employees.

Hunting ground graves were distinguished as a separate category during the 1930s.         There is however no clear definition of what a hunting ground grave is. They have been constructed over a large area over a long period of time (200 BC-1200 AD) and their morphology varies.This paper investigates how the archaeologists have discussed the hunting ground graves since they were distinguished as a separate category until today. It investigates what concepts that have been used to define and categorize the graves as a group. It also investigates if the choices of concepts are depending on a broader societal perspective.To find the answers to these questions two surveys have been done.
