Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

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).

Utvärdering av tillgänglighet på Stora Ensos massabruk i Skutskär

Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

Biologiska bekämpningsmetoder i hemträdgården :

Biological pest management is defined as control of pests using their natural enemies. This method has been used in Sweden since the 1970´s and it has been developed ever since. Biological pest management is today relatively common among commercial growers but there are good possibilities to apply this method in the home gardens as well. The aim with this thesis is to compile a report from both the companies that are marketing the products and the home gardener´s point of view. This should give a better understanding of the market and how it could be improved. We will give examples of products that represent the different kinds of organisms that are being used in biological pest management. Our hope is that this will be an introduction to all interested in biological pest management. The legislations regarding registration of organisms are still a matter of discussion and are causing problems to producers, distributors and the market in general. Why isn´t biological pest management more common in the home garden? The main reason appears to be the lack of knowledge in the subject. What are the benefits using biological pest management when it requires so much knowledge and it´s more expensive than Conventional pest management? With the environmental problems we face today, we hope that every single gardener has an interest in developing an environment as clean as possible, even if only in one's own backyard..

Musikens oanade effekter - En studie om musik i dagligvarubutiker

The retail industry is complex and when it comes to the in-store environment Conventional marketing tools seldom find their way. The impacts of in-store atmospherics on customers and the psychological impact the store environment has on their decision-making are rather remarkable. An in-store atmospheric that often is used in order to affect customers is music, in fact it is one of the in-store elements that has been investigated more carefully. Nevertheless, in spite several studies on music and its impact as an in-store atmospheric on customers, it is not yet obvious what applies. To bring some clarity on the subject this study is aspiring to explain what applies when it comes to playing music in grocery stores.

Fred ? till vilket pris? ? En studie om etiken kring kärnvapeninnehav

This bachelor thesis focuses on the ethics concerning the possession of nuclear weapons seen from a deontological and utilitarian perspective. I have also considered the aspects of International law, the Just-war Theory, and Michael Walzer's Legalist Paradigm. The research question that guides my essay is: Is it possible to ethically justify a country's possession of nuclear arms, which results in direct and indirect threats against other countries?I have chosen to focus my essay on the period of 1945 to 1990, also referred to as the Cold War. I find the bipolar system that existed between the USA and the Soviet Union as a good empirical example, during which the nuclear arms debate constantly took place.The result that my thesis brings is rather ambiguous.

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..

En analys av hur subjektspositioneringar kan påverka rekryteringsprocessen via internet

The purpose of this thesis was to study descriptions of companies on their webpages on the Internet. This was performed from a socialconstructionist point of view with focus being on subject positionings and gender. A critical discourse analysis was carried out on two texts from the webpages of two organizations on the Internet. Using the three dimensional model for critical discourse analysis by Fairclough, the discourses and subject positionings that the texts included could be revealed. The purpose of this thesis was also to point out the importance of the use of language in recruiting personnel and to hopefully encourage organizations to put effort into text production to avoid discrimination.

"Min ros du är som en älskling, dina fåglar äro händer" : Språk och verklighet i Stina Aronsons Feberboken och Martina Lowdens Allt

Who tells the true story of the world? The western civilisation is highly influenced by the written word. The writings of ancient philosophers, poets and religious authorities still have a strong cultural impact. Myths and religion as well as philosophical and political systems effects our self-concept. These models are all unified by there ambition to explain mankind and tell the story of reality.This essay examines two published diaries in order to discuss their relation to the common story of the world.

Potential för värmeåtervinning från mjölkkylanläggningar

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with Conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

Användning av könssorterad sperma i nötkreatursaveln :

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

Bildlärares kamp om att få sina röster hörda hos ledningen

Sara Lidman?s second novel Hjortronlandet (1955) unfolds in the north of Sweden in the early 20th century. It describes the progress of modernity and the conflicting interests of an old local culture and a new more ?civilised? one. The two cultures are constituted by different value systems and in the novel they are represented by two neighbour communities.

Drapering av en illusion : En komparativ studie med utgångspunkt i fotografierna av Leila Khaled och Shirin Neshat

The aim of this paper is to perform a comparative study between the photography?s of Leila Khaled and Shirin Neshat in order to observe if the woman are able to recede from an Conventional formation to become the bearer of the veil and not only reduced to that whichneeds to be concealed. From a feministic perspective I have observed how the symbolic of the veil moulds the woman and how the woman in her context moulds the veil.In the description of the news photography of Khaled and the art photography produced by Neshat the mechanisms that lies as a foundation for the modelling of the portraits becomesthe essays primary entrance. Mechanisms that evolve around the creation of the woman as aconcept, a subject shaped for being looked at and the woman?s self-image through others.The textual discourse is visually enhanced through a comparative picture material visually enhanced and explained through photographs by the contemporary artist photographers Cindy Sherman, Catherine Opie, Laurie Simmons, Robert Mapplethorpe and Elin Berge.

Ett Radikalt Högerpopulistiskt Parti i Regeringen : En studie av FPÖ och dess valframgång i Österrike 1999

In this research paper I have interpreted and analysed how it is possible for a Radical Right Populist Party such as FPÖ (The Freedom Party) to obtain electoral success in the end of the last millennium. In 1999 they were elected into the national legislative parliament with 26.9% of the votes and participated in the Shüssel government from February 2000. I believe this is an extreme case study and my method is the so called Disciplined-configurative case study. I?ve conducted this study by using earlier published research and than dividing these old theories into to three analytical categories.

Den dolda kompetensen : en longitudinell undersökning mellan åren 2007 - 2009  av fem gotländska småföretag

In this thesis we will discuss the importance of human resource development in smaller companies and if it will change from when the Swedish economy was in an economic boom and later on came to be in a recession. We choose to use a more qualitative approach for this research in order to conduct a more in-depth study of five smaller sized companies located on Gotland, Sweden. In order to limit our research we had as an ambition to answer these following questions:? What obstacles are there when it comes to human resource development and knowledge transference within smaller sized companies?? What can simplify or enable human resource development and knowledge transference within smaller sized companies?? Does the teaching process change to a more tacit human resource development between co-workers when there is less room for Conventional human resource development?The result of the research came to show that the biggest barrier, when it comes to competence development within smaller companies, is time. However, our research also showed that a majority of the companies has changed from a more external educational plan to a more internal educational plan which focuses on keeping the human resource development within the company.
