The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be Defined, like model order and control signal penalty, but is relatively robust for variations in them.

AbstractRelationships between white women and black men have become a topic of interest in various discussion forums. By examining different arguments within certain discourses, it becomes clear that discourses that have a distinct autocrat outline, i.e. a closed and declaring nature which excludes alternative discursive arguments, also define these relationships as different and deviant in comparison to relationships that does not encompass and include the constellation white women and black men. As a result of the use of autocrat discourses the white women and black men who enter into relationships are displaced and positioned as subaltern. A position which, on the one hand, allows for uninhibited criticism, but, on the other hand, and most importantly, it is a position from where they can be Defined by others.

The aim of this study is to discuss how public officials, who are implementing integration policies, describe and relate to ?immigrant women?. The analysis is based on interviews with eight public officials. Drawing on perspectives from discourse theory, multiculturalism, western feminism and postcolonialism, the diskussion tries to place the interview statements within a theoretical debate concerning the concepts of culture/ethnicity and sex/gender. The picture of the ?immigrant woman? seems to be somewhat revised.

The purpose of this essay is to study the process of developing electronic subject guides for the Internet. Our focus is the content, structure and layout of the subject guide. The study has resulted in a number of guidelines that may be of help in the development of future subject guides. To achieve this purpose we have studied the existing subject guide at one of the faculties of the University of Lund, Sweden. We performed a series of interviews with the originators, and made a questionnaire for the users.

This thesis investigates how the optical properties of paperboard influences printing with targets in ISO 12647-2. The targets for optical properties in ISO 12647-2 are Defined for paperboard without optical brightening agents and fluorescent brightening agents wich makes it difficult to reach the targets when printing paperboard containing these agents.Seven different types of paperboard, some with and some without the agents, have been printed and instrumentally andvisually measured to see if there is any deviation from the standard targets and if it shows visually.The result shows that paperboard containing optical brightening agents and fluorescent brightening agents can print with targets in ISO 12647-2 but in many measurments the difference between the types of paperboard were to small to assess. The differences between the types of paperboard in the instrumental measurements did not fully correspond with the waythe panel appraised them visually..

Title: Organic / Synthetic in today's creative music making. This work intends to find out what synthetically versus organically produced music means for a songwriter / producer as well as for an artist in their everyday role of occupation. What are the positions regarding these two methods and how do they relate to these concepts? This study also concerns the general view of music produced with each one of these methods and to which extent there exists prejudice towards them. The method used for data collection is qualitative interviews.

This study attempts to answer the question of whether the propaganda of the Swedish political parties ?Socialdemokraterna?, and/or ?Sverigedemokraterna?, used for the election to the European parliament 2009, are to be viewed as populistic. Furthermore, is the propaganda to viewed as included in the ?Classical populism?, the ?New populism?, both, or none of the above genres? With a theoretical approach deriving from earlier works on the subject Classical/New populism from a number of writers, the study uses empirical and qualitative text analysis to study the parties propaganda. For each of the two genres of populism an ideal type is set up, which is used to define their core elements.

The essay begins by asserting that the theoretical approaches of men?s violence against women are just as important to study as its extent. The purpose is therefore to analyse and compare two theoretical approaches which is done by a comparative text analysis of two texts written on the subject. The essay attempts to answer two questions; what the theoretical approaches are and how they can be understood in light of feminist theory.Previous research on men?s violence against women discuss especially three theoretical aspects.

The purpose of this study is to look at the line extensions of the Swedish dairy company Skånemejerier. We have chosen to focus on how trends in ecological products and Functional Food influence the line extensions. The competition in the food sector have made it harder for companies to be seen in the market area and the companies have to make their brands more visible. That is one of the reasons why companies work with line extensions. The study is based on a qualitative approach because we wanted to come closer to our subject in order to establish a greater understanding for the case itself.

When contemplating entering an alliance the rationale behind the decision should differ depending on the size of the companies involved as well as on other important factors. The important factors influencing the decision are related to the resource pooling potential of the alliance, the power structure along with the business network the companies are a part of. The analysis has shown proof of a need for cooperation if one wish to succeed in the telecommunication industry and it has also determined which resources that are deemed to be most important to get in touch with, for our study object, to facilitate its access to the market. Those resources are Defined as a direct channel to the customer, funds/capital and the access to relevant business networks. To get in touch with these lacking resources, three alternative approaches has been proposed; all of them involving a strategic alliance decision.

The purpose of this study is to examine how the concept multiculture has been Defined and used in selected articles, which were published during the year 2006 and the following month. The study is based on five Swedish newspapers, from which 57 single articles were chosen and divided into total seven categories and dimensions which were partly developed from the theoretical base and partly from the chosen material itself. By using a qualitative analysis I have found following: In most articles the concept multiculture is used in an anthropological sense, meaning that the presence of several anthropological cultures is claimed before the concept multiculture can be real. An anthropological culture is of varying size and contents, in the majority of the articles an anthropological culture consists of a non-western and foreign country but can also represent a region or a continent. Aesthetic culture is, for the most part, used primary as an aid to define the current anthropological culture and not to stand for its own belonging to a specific genre..

This paper presents the results of a workplace study of two smaller companies in the design industry. The core issue has been to investigate the companies use of technical tools and to what extent social praxis influence the daily work. The methods used are based on a qualitative analysis of interviews and observations. Various kind of work procedures, such as verbal and computerized, have been identified, but the most important occurrence was how spontaneous conversations between employees required certain flexibility, since the actors repeatedly were required to change focus and quickly perceive different information. For that reason, a thesis has been Defined regarding how the use of spontaneous communication put an indirect need of a flexible working environment and also how this lead to more significant participation and exchange of information, as well as more awareness at the companies..

The invisible entrepreneurship is a study of owners of businesses with foreign heritage. It describes the unexplored relationship between ethnicity and class within this group of entrepreneurs.The result of the study is a model which I have found to be suitable to use when depicting the relationship between the ethnic profile and class. The model indicates that the importance of ethnicity decreases as both the owner of, and the business reach a more prominent class. The method of collecting data has been interviews with owners of businesses and Grounded theory has been used to analyse this data. Theories on ethnicity, owners of businesses with foreign heritage, and class in relation to ethnicity have been discussed on the basis of social constructivism.

Citizenship information is Defined as the information the citizen needs to be able to take part in and influence the society. Since it is a democratic issue that information concerning the citizens role in society really reaches the citizens, it is of importance to study how the citizens proceed when they have a need for this information. The aim of this Masters thesis is to investigate how our eight informers proceed when they experience this need in a non-work situation. We performed qualitative interviews. The most important part of our interviews was the introduction of some fictitious problems to the informants.
