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).

This thesis aims to investigate the information effects of fair value accounting in Nordic real estate companies. As a consequence of the mandatory IFRS adoption in the European Union in 2005, listed Nordic companies are allowed to recognize investment property at fair value in accordance with IAS 40. Theory suggests that fair value accounting should lower information asymmetry. Therefore, this study aims to examine correlation between fair value accounting of investment property and information asymmetry on the stock market. To investigate this, we use bid-ask spread as a proxy for information asymmetry and examine Nordic real estate companies before and after the implementation of IFRS.

In printed text, sound is a somewhat forgotten aspect. The recitation of text is vital in areas like poetry and oratory, but still has no distinct technique of being communicated. Emphasis of a word might be expressed through italics, but no canonic character set or system for vocal delivery of texts exists. With this essay we are creating a foundation for a development of such a character set or system. By studying existing visualisations of sound and comparing these with semiotic and perception-based theories we obtain useful insights for a prospective system for visualisations of vocal sounds.We conclude that the aspects of sound one wants to visualise must be carefully defined since the viewer cannot process infinite amounts of information.

Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.

Dark Tourism is a relatively new concept, but as a phenomenon it has existed for centuries in the form of pilgrimages and gladiator games. The term includes visits to places associated with death and disaster, and has in more recent years become a highlighted tourist niche. This paper addresses the phenomenon of Dark Tourism and the reasons behind a visit to such an attraction. To find out the motive behind people's visits, interviews were conducted with respondents who have previously visited one or more Dark Tourism sites. A total of 32 people were interviewed about what influenced them to go to such a macabre place.

Vi har varit en grupp på fyra studenter som på tio veckors tid skall ha utvecklat några applikationer, samt ett bibliotek för att kunna hantera diverse gester till ett system som kan hantera flera användare samtidigt. Vi har fått i uppdrag av Luleå Tekniska Universitet att prova denna relativt nya teknik och se vad den kan ha för kapacitet och användningsområden i framtiden. Min uppgift i arbetet var att hjälpa till att utveckla ett bibliotek för att hantera olika gester som en användare kan tänkas göra. I detta examensarbete så berättar jag om hur man skall kunna upptäcka komplexa gester i ett system där flera användare kan påverka samtidigt. Jag kommer med denna rapport att ta upp de problem jag har haft, vilka lösningar jag har kommit fram till samt vad jag ser på möjliga framtida tillägg till biblioteket.

Sjukdomen orsakar funktionsnedsättningar av olika grad och omfattning. Ett dominerande symtom vid multipel skleros är smärta. Syftet med denna litteraturstudie var att hitta omvårdnadsåtgärder, som kan lindra smärta hos personer med sjukdomen.

That we have a great need to be encouraged is coated in a variety of motivational theories. Despite our awareness of this need, studies show that Swedish employees feel a lack of encouragement in the workplace. The purpose of this report is to examine the factors that affect our ability to give others encouragement.Empirical data were collected through questionnaires from 91 people in the workplace. Correlation between the experience of giving and receiving encouragement, self-image, outlook on mankind and stress in the workplace are examined using a linear Multiple Regression Analysis. Correlation between the experience of giving and receiving encouragement is examined using Pearsons test of correlation.The results show that there is no significant correlation between the experience of giving and receiving encouragement, self-image, outlook on mankind and stress.

The aim of this study is to investigate which management control mechanisms evolve in companies that receive funding from Venture Capital companies and why the management control systems evolve in the way that they do. A case study was performed on three Swedish high technology companies, that all received funding from Venture Capital companies for the first time in 2006. Merchant?s framework, defining all management control mechanisms as either, results control, action control or personnel control, was used to structure the study. Results show that the companies that received Venture Capital all increased the use of management control mechanisms within results control, action control and personnel control.

This Master's thesis examines some aspects of children's books for 9-12 year olds, and the children's books market, from a gender perspective. The main objective is to make a gender analysis of attitudes among children and other agents in the book market towards children's books of different qualities. Children's reflections on gender roles in the books and the importance of gender aspects for publishers in the field, are investigated. A combination of methods are used, including literary analyses, surveys of publication lists of the BTJ group Bibliotekstjänst interviews with children and questionnaires sent to children as well as to Swedish publishers of children's books. The analysis of children's books clearly shows that images of gender roles vary in different kinds of books which supports theories of gendered literature.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

This master thesis states the following questions: Is it easy or difficult to retrive information from a mobile phone manual? How can the search process be described among user for a mobile phone manual? What similarities and differeces can be identified between users? Arhe there any variables that affect search performance such as reading skills or technical domain knowledge? Eight mobile phone users participated in an empirical observation and the scope was to find information in a paper version of a mobile phone manual according to given tasks. The results shows that some users has problems to retrieve information due to that the correct page in the mobile phone manual could not be located. The results show that the user is using several search strategies, for example the table of contents and the index, when trying to locate information. The results also revel that the user initiates multiple search steps before the correct information can be located.
