Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens. Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions. The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.

The rise of the Swedish Democrats, as a political party in Sweden, has been surroundedby controversy both within and outside of the media. As such a polarizingtopic, the party has been the focus of negative and positive attention. On onehand it has been considered a racist and xenophobic party due to its policies onimmigrants. On the other, it has also been seen as a solution to what has been consideredby some to be a constant problem in Sweden, for those same policies.These policies are motivated by what the party perceives as a threat to Swedishsociety. That is to say, immigrants are a threat to Sweden because of thechanges they impose on the Swedish identity.

This thesis examines the municipalities of Västra Götaland and the way they are prepared for crisis communication towards people with a foreign background. Over the past years there have been several studies that have examined the issue of crisis communications towards minorities but these are often focused on the target group. In this study, I focus on the authorities' actions. The theoretical approach is primarily an intersectional one and in this way the thesis is centred on the creation of different categories, the relationship between these categories and the possibilities working with these at the municipalities.On behalf of Region Västra Götaland, this investigation began with a survey that went out to the communications officers in charge of the crisis communication in each municipality. The ambition was to clarify the preparedness of each one and show how they relate to one another.

The amendment of a law which is expected to come may well have a significant impact on the Swedish real-estate broke market. The law change will probably have an effect in the number of ways real-estate brokers will compete as a result of the increasing variety of services offered. In order to gain competitive advantages brokers must be at the forefront in the development regarding the changing market. To do so requires that the company chooses an appropriate range of peripheral services that are profitable. The problem is to choose the ?right? services to convey. The purpose of this paper is to describe the services that are in demand for transmission and how the agents can work to meet the demand of this new market.

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

This essay concerns PR-consultants and their view on their work. The purpose was to find out which type of communication they use in contact with the target. By target, we mean the group of people the employer wants to reach with help of the PR-consultant. For example: Jägarförbundet wants to get help from a PR-consultant to influence someone in the government so that Swedish hunters can shoot more wolves, than the target group is the one in the government. We also wanted to find out if the PR-consultants are aware of the image the public have of them and if they are trying to change it into a more positive one, by using more ethics, openness and to have more focus on the relations aspect.  PR in the future with new social media (like Internet) was also a subject, where we wanted to know how much they involve social media in their work.  Our main questions were:How do PR-consultants relate to openness in communication, ethics and social media?Which one of Grunig?s PR-models is most occuring in the PR-consultants work? We made a qualitative study where we carried out interviews with six PR-consultants.

Today, activities funded with public funds needs to present relevant and reliable information which shows the results obtained. Requirements increase in welfare activities to be run based on scientific, empirical knowledge. This applies particularly to social work. The social work is, however, poorly researched in areas such as knowledge of interventions in the content, context and effects. One way to evidence-base social work can be to conduct regular and qualified assessments.

This essay examines a presupposed correlation between the way one look upon values and the way one look upon the will of the people in a theoretical democratic context. The more specific purpose is to test the following hypothesis: There is a reversed connection between the way one look upon values and the way one look upon the will of the people in a theoretical democratic context, that is; a strong claim of values give reason to a limited conception of the will of the people and a weak claim of values gives reason for a more unlimited conception of the will of the people.In order to test the hypothesis I examine three different conceptions of democracy, these are: pluralist democracy, deliberative democracy and constitutional democracy. I analyze the way they look upon values, there view of the will of the people and finally if there is a connection between the way they look upon values and the will of the people. Values should be understood in a metaethical context. In other words it is not values in the ?common? meaning, instead its how val-ues in them selves should be understood, and even more relevant, what we mean when we ex-press values.My conclusions are, first and foremost, that there is a correlation between the will of the people and values, according to the formulation of the hypothesis.

This is an investigation into the ways in which a group of librarians experience and make use of the intranet in their vocational role. The theoretical frame of reference consists of a model of how professionals seek information, which is based on a role-theory. As a method, I have applied a qualitative case-study. Using semi-structured qualitative interviews I have interviewed five librarians and the webmaster responsible for the intranet in their library. I have investigated how elements such as the age and vocational role of the librarians affect their use of the intranet.

This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.
