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..

The aim of this paper was to examine how social workers' comprehension of the need of financial aid exists in, and is influated by, the organisation they work in. To investigate this, we asked ourself questions concerning how the social worker view the way that the finicial aid-system and work surrounding it is formed, whether the social worker's understanding of the need of financial aid co-exists with the percieved common understanding of the work place (do the understandings coincide, do the social worker adjust his or her understanding or is it possible to have a separate understanding), whether the social worker feel that he or she have discretion to influence the organisation and how possible conflicts between different views are handled. We felt that a qualitative method would best help us answer these questions. We therefore interviewed seven social workers working in the same organisation. We then looked at our material from an organisational theory perspective, focusing on the individual in the organisation.We found that the social workers were socialised into the organisation and adapted the norms and values that existed there.

This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.

Abstract  This paper examines the Copenhagen Climate Conference held in the Bella Center in Copenhagen, December 2009. The aim of this paper was to analyse the highly anticipated conference, and why it did not result in a binding protocol between the world?s states. The focus of this paper was to examine two key actors in the Copenhagen negotiations: the people?s republic of China and the European Union.

Today there are various methods to use when euthanizing horses. Earlier the use of free or captive bullet was the most common method, but in recent decades this has changed and chemical euthanasia is now considered the most common method. The chemical euthanasia has in Sweden been dominated by the use of barbiturates. Somulose® entered the market in the beginning of the 90?s as an alternative to previous chemical euthanasia.

Twice as many women as men suffer from mental ill-health. The negative trend of mental problems among teenagers continues. In certain places in Sweden, 40 per cent of the teenage girls have outspoken symptoms of depression. This is why it is important to observe mental ill-health in a public health perspective. One effect evaluation of the DISA method (Depression In Swedish Adolescents) drew the conclusion that this universal depression preventive method is well working. The DISA method includes cognitive behavioural techniques that change negative pattern of thinking, give practice of communication, strategies of problem solution plus exercises to strengthen the social network.

The purpose of this work is to examine how ecotourism exists in Sweden. In order to answer this, the essay has been based on a qualitative method, which means that the authors have mainly used depth interviews for information gathering. Some of the empirical work is also done using the qualitative method, by gathering statistics, figures and scientific articles. The essay is divided into various chapters to give the essay a clear structure and for the convenience of the reader. The part that have been of most use and support for authors is the depth interviews with the interviewees.

In my paper I have examined the United Nations role in the democratization of Kosovo. In order to complete this purpose I have asked two questions? How has the UN contributed to the democratization of Kosovo that has taken place so far?? What advantages and/or disadvantages has the UN presence in Kosovo had from a democratic perspective?The method I have used in my paper is a qualitative one, and more specified a qualitative text analysis. This means that I have examined a rather small number of sources, but in return I have analyzed these sources very carefully. In addition to the choice of a qualitative method I have used Robert A.

The study is about the collaboration between assistance administrators and unit managers. The aim of the study was to understand the assistance administrators and unit managers interpretation of the concept of collaboration, as well as their experience of collaboration in the practical work in elderly care in the common work around care recipients in the evaluation and execution of home help services. The analyse of the interview material was conducted by using collaboration and New Public Management (NPM). We used the qualitative method in our study with semi-structured questions. The interviews were transcribed, coded and thematised based on our questions. When interpreting the interviews we used the hermeneutic circle in which we analyzed the study's various parts and then attached them to the collaboration, NPM and also to earlier research and to each other. The conclusions that emerged raises the important factors for collaboration and could be linked to collaboration, NPM and previous research.

Networking is an important part, for organizations, in the recruitment process. This since the emergence of Internet networking has become more common and the organizations finds that networking is applied more frequently in the recruitment process. Organizations have noticed that networking often is a more cost efficient option compared to traditional recruitment. Since networking in the recruitment process has increased, we intend to investigate if and how it affects the composition of organizations. This thesis aims to examine networking in the recruiting process, and aims to make no differences between networking offline and online.

The aim of this thesis is to examine one part of Amazon.coms recommender systems: Similar Items. The purpose is also to show the difficulties with subject access, i. e. to find a similar book to the one you just read; problems with traditional systems versus the usefulness with recommender systems like Amazon.coms Similar Items. Similar Items presents a set, a cluster of related items to a given item based on customers co-purchase.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

This study has its background in the debate about religion and the existence of God, which has been an ongoing issue throughout the Western cultural tradition. Today´s information society has been an impact on the increasing interest for this subject. The essay?s main task is to accomplish a rhetorical analysis of two books, Illusionen om Gud (2008) by atheist Richard Dawkins and Guds dödgrävare (2010) by Christian John Lennox, in order to investigate the authors? use of rhetorical strategies to influence their audience. The texts are studied using a qualitative approach with the theoretical basis of some well-defined rhetorical variables: ethical, logical and pathetic means of persuasion, propaganda, and the important factor that a message always is presented in a certain context in which the recipients both have their own values and subjects to general truths and common frames of reference.

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.
