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).

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..

Frågeställning: Finns det någon effekt av handelshinder och korruption på de central- och sydamerikanska ländernas tillväxt?Teori: De teorier som används i undersökningen är Solows tillväxtmodell, Ricardo modellen, Heckscher-Ohlin modellen, teorier kring handelshinder och infant-industry-argumentet.Metod: De studieobjekt som undersökts är länder i Central- och Sydamerika och hur dessa länders tillväxttakt sett ut mellan åren 2000 och 2007. Det tillvägagångssätt som valts för att genomföra denna undersökning är, att utifrån de data som samlats in, genomföra en regressionsanalys för att se om de variablerna, som tagits fram för undersökningen, har någon påverkan på tillväxten hos studieobjekten. Utifrån regressionsanalysen genomförs en jämförelse med de teorier som finns i undersökningens teoriavsnitt. Detta för att se om de fenomen som framkommer i regressionsanalysen kan förklaras av de teorier som finns inom ämnet.

In this Bachelor essay I will discuss my thoughts about choir intonation and especially with an amateur choir, Stämbanden, who has little experience when it comes to work with choir intonation. I describe my thoughts as I am working with Stämbanden. I will discuss a few choir intonation exercises that focus on working with intonation while singing that I have put together from other exercises and made adjustable to fit Stämbandens? needs. I will later evaluate the process and discuss further ideas and thoughts on how to work with improving any choir?s intonation..

Bakgrund: För föräldrarna till ett spädbarn har barnets sömn stor betydelse. BVC-sköterskan är den som främjar barns hälsa och ger föräldrastöd. Syfte: Syftet med den här studien var att beskriva BVC-sköterskors erfarenheter och redovisa reflektioner kring för­äldra­­­­stöd som rör sömnfrågor hos spädbarn upp till ett års ålder. Metod: Stud­ien hade en beskrivande design med en kvalitativ ansats och genomfördes via semi­struk­tur­erade intervjuer med åtta BVC-sköterskor inom BVC-verksamheter i en mellan­stor svensk kommun. Materialet har analyserats med kvalitativ innehållsanalys.

The purpose of this study is to investigate how the Swedish municipal welfare system, in their capacity as discourse makers, construct Intimate Partner Violence (IPV) in the relationships of Lesbian, Gay, Bisexual and Transgender (LGBT) people. A discourse analysis of their official plans of action regarding IPV and the information directed towards their citizens through their webpages showed that the discourse surrounding IPV revealed a gender dichotomy, where the victim was mainly constructed as being female and the perpetrator as male. As a consequence of this, gay and bisexual men were rendered invisible from the discourse surrounding victims of IPV, although they could be included in the construction of perpetrators of it. Lesbian and bisexual women were often included in the understanding of victims of IPV, but in the discourse surrounding perpetrators of it they were made invisible. The discourse about IPV also excluded the experiences and vulnerability of people who identify as being transgendered.

The purpose of this essay is to discuss different memory techniques used by pianists so I can feel secure while performing during concerts. How do pianists learn to memorise music? According to me, are certain memorisation techniques more effective than others? Do pianists use different methods depending on repertoire? To find my answers, I have studied two other pianists? outcomes on the subject as well as applied my chosen memorising techniques on five pieces from different epochs. These techniques include visualising my fingers when they play on the keyboard, listening to the pieces many times, practicing short specific parts one hand at a time, singing the melody while playing the accompaniment, studying the scores without playing, as well as analysing the harmonic sequences..

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

Studien syftet är att undersöka om barn som har ammats längre än ett år har ökad risk för karies före sex års ålder. Metoden är en systematisk litteraturstudie där databaserna Cinahl, Cocharane och PubMed har sökts. Resultatet baserades på fyra kohortstudier och tio tvärsnittsstudier. Resultatet av dessa fjorton studier kan indelas i två riktningar, studier som visar att amning längre än ett år ökar kariesrisken och studier som indikerar att amning inte ökar risken för karies. Slutsatser: Utifrån resultatet av artiklarna får det anses att det vetenskapliga underlaget är otillräckligt för att hävda att amning ökar risken för kariesutveckling..

Swedish consulting companies within the architecture-and engineering business exist on a market that is distinguished by an increasing globalization and internationalization. The companies? commissions are based mostly on long-term, personal clientele. These relations are threatened by a huge number of coming retirements and high employee turnover.Consequently these companies need to improve and strengthen their relationships with existing customers, to create long-term employee and customer loyalty. The purpose of this essay was to analyze and evaluate consulting companies´ internal marketing.

The purpose of this thesis is to examine the performance of different types of queries in the AltaVista query-based search engine. Thirty information needs have been collected from an ask-a-question service on the World Wide Web, which means that they are based on real users information needs. This is done to avoid partiality in the study. The author has invented different types of queries for each and every one of the information needs in accordance with the search syntax available for AltaVista. The types used are Boolean expressions, queries including proximity operators, phrases and queries directed towards a specific field.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

I oktober 2006 presenterade jag för Utbildnings- och kulturförvaltningen i Markaryd idén att samla sångintresserade i Markaryds kommun till en projektkör för att uppföra ett större körverk med orkester. Målen med projektet var att stimulera till ökad sång- och körverksamhet i skola och kommun och genom denna aktivitet, dels skapa närkontakt med klassisk musik, dels att bygga broar mellan olika grupperingar i kommunen. Då man år 2007 firade Markaryds kommun 700 år, Markaryds kyrka 150 år och Linné 300 år tillkom aspekten att projektkören skulle kunna bidra med en konsert som avslutning på jubileumsåret. Min forskningsfråga i detta arbete är: På vilket eller vilka sätt har projektets målsättningar uppnåtts? Skriftliga utvärderingar med de deltagande körsångarna, reaktioner från kommunen, press och allmänheten samt en DVD dokumentation utav konserten ligger till grund för min resultatdiskussion.
