The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

To create a more accessible environment for disabled people, the Swedish government, in the year of 2001, made the national act of easily eliminated obstacles valid. This national act states that all easily eliminated obstacles in the municipalities, in places and in premises that are public, shall be removed before the end of 2010, no matter if the owner of the place or premise is private or public. According to Boverket, most of the municipalities are not going to be able to reach that goal, why? The aim of this thesis is to compare the two municipalities Kalmar and Karlskrona in their way of implementing this national act, to see where it went wrong and why. By using implementation theories and qualitative empirical data in the form of interwievs with the total of eight people from different administrations in both of the municipalities, the subject was analyzed and discussed.

Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.

Syftet med denna studie var att beskriva betydelsen av studie- och yrkesvägledande aktiviteter med barn i åldrarna sju till tolv år. Kvalitativa intervjuer genomfördes med sex examinerade studie- och yrkesvägledare som bedriver studie- och yrkesvägledningsverksamhet med barn i grundskolans år 1-6 eller fungerar som stöd till pedagoger som arbetar med studie- och yrkesorienterande verksamhet med barn i dessa åldrar. Resultatet visade att intervjupersonerna anser att arbetet måste påbörjas tidigt, helst redan i grundskolans första år, för att målen så som de skrivs fram i de nationella styrdokumenten ska kunna uppnås. De förutsättningar intervjupersonerna menade krävs för att tidig vägledning ska kunna bedrivas är av såväl strukturell som av individuell art. Slutsatsen som drogs var att studie- och yrkesvägledande aktiviteter som påbörjas i grundskolans tidigare år och som följer elevernas kognitiva utveckling kan medverka till att eleverna ökar sina förutsättningar att göra väl underbyggda val i framtiden..

This essay is called What kind of history? and is about how history teachers think when they chose what to teach about and why. In the curriculum there are no guidelines about what substance you have to teach about. This gives the schools and teachers a big freedom. At the same time there is a kind of informal canon which says that it is the European perspective that is the important one.

Detta är en kvalitativ uppsats med syfte att ge en inblick i hur ett antal läroböcker och lärare valt att belysa Sveriges nationella minoritetsspråk i Svenska B på gymnasiet. Jag har analyserat fem läroböcker böcker i svenska, samtliga utgivna efter år 2000. Analysen visade att alla analyserade böcker utom en har gett minoritetsspråken mycket lite utrymme. Informationen i majoriteten av böckerna fokuserar på vilka minoritetsspråken är och vilka rättigheter de sedan 2000 erhållit. I tre av de analyserade böckerna nämns den historiska aspekten men informationen är ofta tagen ur sin kontext.

A central question is what view of communication is dominating in a municipality in the southern part of Sweden. The study deals with communication theory from two different perspectives; the view of transmission and the view of creation of meaning. Falkheimer and Heide (2003) claim that the view of transmission is one-way communication where the receivers apprehend passivly. In the view of creation of meaning the goal is to develop and strengthen the common notion that exists in a group. Empirical studies were done, that consisted of qualitative interviews with politicians, directors of the municipality, and principals from three childcare and school areas, and also from one upper secondary school.

Children that are taken care of for institutional care by the social services are unprivileged as a group. When society takes over the parenting role, it forces local governments and other accountable authorities to guarantee these children satisfactory support and good care according to each child's needs. The aim of this thesis is to analyze and discuss problems with implementation in policy processes when authorities incorporate. From the normative standpoint of legal security and the United Nations Children's Convention, this thesis investigates the consequences of interaction between two Swedish supervisory authorities for the social services: Socialstyrelsen and länsstyrelserna. To fulfill the aim I will investigate the approach taken by the authorities and the work division between Socialstyrelsen and länsstyrelserna.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera Steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

The implementation problem refers to the situation when political decisions are not implemented as intended by the decision makers. In this thesis I examine how one part of the new school reform GY11 has been implemented in Social Science in high school in Sweden. The part that interests me is entrepreneurial learning. Using implementation theory, and the actor properties understand, can and will, as described by Lennart Lundquist, I have interviewed five high school Social Science teachers in Malmö and Lund. The result was that they all understood the concept of entrepreneurial learning.

In 2002 the local council of Lund, Sweden, decides to implement the UN Convention of the Rights of the Child. A number of actors, such as the state, the civil society, the political society and the bureaucracy, participate in the political process with different authority and points of departure. This thesis studies the actors´ interactions from an inside perspective by applying concepts such as political power, democracy and implementation. The methodological departure is action research from within, a local NGO, the local board of Save the Children Sweden. The results of the study indicate that governance and Steering of the implementation process at the communal level is weak.

During the last years a discussion has emerged around problems with Swedish state boards trying to influence the public opinion and even political bodies through different kind of information efforts. Several observers inside and outside the academy have studied how state boards increasingly use information as an instrument and also how political bodies increasingly have given such instructions to state boards. This essay put those studies into the context of both information political history and previous theoretical interpretations in that field of research.The analytical tool consists of four ideal typical ways ('state opinions') to arrange relations between the state and the citizen. Some critics focus on problems with too much political Steering and how political majorities uses state boards to spread ideological propaganda. Others highlight problems with autonomy and bureaucratic organizations taking initiatives by themselves to spread normative information.

 The 1st of July 2006 Sweden made a change of authorities in the system concerning the reception of separated asylum seeking children. Prior to the change, the Swedish Board of Migration was held completely responsible for the reception of these children, who arrives in Sweden without their parents or any other relatives to care for them. Since the alteration of the law (1994:137) the responsibility for the housing of these children now lies within the Swedish municipalities, while the Board of Migration still handles their legal commissions. The change was intended to fundamentally improve the conditions under which these children were taken care of. However the implementation took a severe wrong turn when the municipalities weren't prepared for their new responsibilities and the immediate result was alarming. This qualitative study is based upon interviews with the people responsible for the reception of the separated asylum seeking children in the municipalities of Kronobergs County, as well as one of the two people in charge of the new system at the Swedish Board of Migration.

This masters degree is a study of factors of success in a drug preventions work of change and model or method which could facilitate this work. The target group, which is in focus in this survey, is alcohol- and drug coordinators, also called prevention coordinators who?s main task is to develop and coordinate the preventive work in the alcohol and drugs area. My method of investigation is a combination of literature studies and a quantitative poll study with the target group, alcohol and drug presenters?, in Sweden.

The purpose of our study is to interpret and understand the collaborative process around a regional model that is based on state developed guidelines for people with dementia. We have chosen to focus on the importance of interaction and have therefore interviewed participants in the project's Steering committee. This group participates in efforts to develop a model for dementia care in Halland.The project work in Halland, to develop a joint model for people with dementia and their families was initiated in the spring of 2011 and is due to finish at the end of 2012. The Halland model has been named ?Annas led? and is about Anna and her husband Lars and living with dementia.
