This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

AbstractAim: The aim of this essay has been to study how the Swedish church has created the image of their religious activity through media. This has been by studying the three commercial campaigns launched by the Swedish church during the years 2000, 2001 and 2003. Questions asked are: How has the Swedish church chosen to profile it self? Which discourses can be recognized in the campaigns? Which messages has been communicated through the campaigns? How has these discourses created the image of the Swedish church?Method: The methodological framework is critical discourse analysis inspired by Norman Faircloughs? three-dimensional model. Thirteen images all part of the campaigns are analysed using a semiotic method.

The aim of this paper is to examine why Swedish teachers and multilingual secondary   school pupils think it is important to read fiction, how Swedish teachers work with fiction in the multicultural classroom and how they motivate their multilingual pupils to read more by adapting fiction to their capabilities and experiences. We have done interviews with four Swedish teachers and 12 multilingual pupils. The following questions are the starting point of this essay:Why do Swedish teachers and multilingual pupils think that it is important to read fiction?  ?How can the Swedish teachers in the multicultural classroom motivate their multilingual pupils to read more fiction?The result of this paper showed that both the Swedish teachers and the multilingual pupils thought it was important to read fiction because it partly gives themselves the opportunity to acquaint with other cultures and it helps them to improve their language. The teachers motivate their multilingual pupils by reading out loud, reading in groups and by minimizing language difficulties that may occur in the fiction.

The thesis examines the crisis that the Swedish-flagged merchant marine underwent in the 1990s, that resulted in a narrow market for the Swedish-flagged fleet. In order to save the industry, the TAP- agreement was created, consisting of three parties, government- market and interest organizations.  Purpose in this thesis, is to exam how the TAP-agreement was carried out in relation to the parties, and how it correlates in relation to how the global political economy affected the Swedish maritime politics. Two questions are presented. Is the TAP agreement an expression of Swedish corporatism?  Which aspect of Global Political Economy is characteristic for the TAP agreement? A case study is preformed in three steps. The different parties of the TAP-agreement have been interviewed.  A comparative study of two Swedish crises has been performed, in order to establish the correlation between them, in regards to corporatism.  A survey, with the aim to pinpoint which aspect of Global Political Economy is characteristic of the TAP agreement. Findings in this thesis are that the TAP-agreement was designed through corporatism, and that the most important aspect of all, the Swedish flag was worth saving, for all parties. .

The purpose of this master's thesis is to find out what support students of Swedish for Immigrants (sfi) think they get from the public library during their study of the Swedish language. One important aspect in this essay is to examine whether the library can meet the need of Swedish-speaking meeting places where the sfi-students can practise their new language. The method used in this study is qualitative interviews. Nine sfi-students, one sfiteacher and one librarian have been interviewed. A sociocultural perspective on learning has served as a theoretical starting point.

This essay is a qualitative study about Swedish fire-fighters´ ideas of women and people from other ethnic backgrounds than Swedish. The problem in focus is why there are difficulties for those groups of people to be employed in the Swedish fire service. Can there be ideas of these groups which are not favourable for them? And if this is the case, can those ideas be explained by gender theory about construction of masculinity? The purpose is to investigate whether the absence of women and people from other ethnic backgrounds can be explained by the fire-fighters´ ideas of those groups. The study consisted of a one day observation and four one hour long interviews with fire-fighters from different positions within the Swedish fire service.

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

The real estate company Ihus is facing an expansion of its comfort cooling in Noatun,Uppsala, to provide the buildings in the block with cooling. The buildings in Noatunare mainly used for office premises, where the requirements for an accepted indoorclimate is great. However, it?s uncertain whether Ihus should continue, as currently,producing comfort cooling by themselves using a compressor chiller, or if they shouldconnect themselves to Vattenfall?s district cooling net.The purpose of this report is to examine which technique of cooling is best suited forIhus and their buildings in Noatun. It should also work as a guideline for othercompanies facing the same problem as Ihus.

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

AbstractKubakrisen; En tidningsstudie om svenska morgontidningars rapportering kring krisen The Cuban Missile Crisis; A media study of Swedish morning papers reporting about the crisis The purpose of the survey is to illustrate how four Swedish newspapers, Svenska Dagbladet, Göteborgs Handels- och Sjöfartstidning, Dagen and Ny Dag reports about the Cuban missile crisis based on the questions. The survey highlights what distinguishes the morning papers and by how they take the position of the ship blockade against Cuba that United States issued and what position they take on who to blame in the conflict, but also how leaders Khrushchev, Kennedy and Castro portrayed. The study is based on the basis of a newspaper study and theory of priming serves as an instrument for the collection of materials. The survey results show in the first issue of how the papers stand to US ship blockade, which SvD endorses, while GHT and Ny Dag condemns it and Dagen stand in the middle without any real position. Previous studies treated SvD stance during the Cold War, shows that during the Vietnam War in 1965 SvD was very critical of the USA and their involvement. In this study, regarding the Cuban missile crisis, SvD are most clearly pro-US while Ny Dag accuse and highlights strong criticism of the United States. As for Chrusjtjov, Kennedy and Castro, the survey shows that three out of four newspapers writes about a surprised Chrusjtjov, who had gone too far and a Kennedy who are determined and implacable.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Syfte: Syftet med vår undersökning är att skapa bättre förståelse för hur en säljare förmedlar empati för kunden i en säljrelation. Tidigare forsknings uppmärksamhet för förståelsen och empatins påverkan utgör grunden till att vi mer specifikt vill undersöka; hur kunden uppfattar att fastighetsmäklaren förmedlar affektiv respektive kognitiv empati i en säljrelation.Metod: En studie av kvalitativ art valdes med bakgrund till studiens syfte. För insamling av kvalitativ data använde vi oss av tidigare forskning samt semistrukturerade intervjuer, vilka utfördes med respondenter som anlitat en fastighetsmäklare inom de närmaste tre föregående åren. Well-grounded theory användes sedan som analysmetod av det empiriska materialet.Slutsats: Studien indikerar att kunden uppfattar både affektiv och kognitiv empati i mötet med fastighetsmäklaren. Vi har genom analysen uppmärksammat skillnader och likheter i respondenternas svar, mer specifikt har vi funnit att kundernas uppfattning av empati upplevs olika av olika personlighetstyper och situationer.Förslag till vidare forskning: Vi anser att vidare forskning bör ta hänsyn till fler variabler, exempelvis ålder, kön, personlighetstyp eller situation.

With the starting point in UN peacekeeping operations, this essay investigates the participation of the Swedish armed forces and how the Swedish soldiers perceive their role in those operations. The aim of the study was to explore different perceptions about the Swedish soldiers in international operations. Partly from the Swedish soldiers perspective and how they perceived their own role as soldiers. Partly from the perspective of civilians, like Swedish aid workers, and how they perceive the Swedish soldiers. The third perspective was from a person with mixed experiences from both the military and the civilian work.

Under de senaste åren har planprocessen legat i fokus. I Stockholm råder en stor bostadsbristoch de långa planprocesserna som kan sträcka sig upp till fem år eller mer har medfört att ettantal utredningar och rapporter har genomförts för att se vari problemen ligger. De långa ochkomplicerade planprocesserna medför även att konkurrenssituationen mellan byggherrarpåverkas då enbart de större byggherrarna har den tid och resurser att genomgå dennautdragna process. I den nya plan- och bygglagen som infördes 2 maj 2011 fanns en delförändringar som hade som mål att effektivisera denna process men än finns det utrymme förförbättringar.I vårt examensarbete har vi analyserat tre projekt i tre olika kommuner för att se huruvida deutredningar som krävs skiljer sig mellan kommunerna. Kommunerna vi har valt är Stockholm,Solna och Södertälje och för att få en mer nyanserad bild har vi pratat medstadsbyggnadskontoret i Södertälje kommun samt två exploatörer i Stockholm och Solna omderas syn på processen.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..
