Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

SammanfattningCorporate Social Responsibility (CSR) är ett arbetsområde som drar mer och mer intresse till sig, inte minst med inköp och leverantörer i fokus. Ett stort antal akademiska artiklar hanterar ämnetCSR och företag utsätts dagligen för situationer som kräver omfattande CSR-aktiviteter. Dessaaktiviteter skall inte enbart neutralisera hot kopplade till CSR utan även skapa positiva effekter för företaget inom detta område. Litteratur och artiklar inom området fokuserar på hur globala företagintegrerar sociala- och miljöfrågor i deras leverantörskedjor, ofta genom en så kalladuppförandekod (Code of Conduct, även kallad CoC), som leverantörer måste följa för att få leverera till företaget. Trots att artiklarna är många inom ämnet, finns det få som diskuterar hurimplementeringen av dessa uppförandekoder och CSR-frågor skall gå till.

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 goal of this project was to create a web-based, crowd-sourced, correlational database, that easily allowed users to submit objects and receive correlated objects as results. The webservice was created in the web development languages of HTML, CSS, PHP and Javscript, with MySQL to handle the database. Simultaneous development was kept in check with the aid of the source code management system GIT. Upon completion, the service contained several HTML-views, the ability to add and rate objects, a per-object dedicated page with information parsed from Wikipedia.org, and a view with objects ranked in accordance to the preferences specific to the current user. Roughly a month after the beginning of development, the website was publicly launched and promoted in order to collect data, and improvements were added to the website as needed.

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

This study is about people with Asperger syndrome and their difficulties in all kinds of communication in society. Through the language we code objects and events to remember and observe the environment. The aim is to compare research with the actual experiences of people with Asperger syndrome, in relation to their difficulties in society / communication. Three questions have been given extra attention. The first is what similarities and differences there are between people with Asperger syndrome.

The purpose of this paper is to explore what objects that can be seized and how the management of a seizure should be conducted. Ability to take enforcement against an individual should be carefully weighed against the rights and freedoms that exist. Seizure is one of the various restraints that exist, and the regulation on which they appear is mainly in the Code of Judicial Procedure, Chapter 27th. To be able to apply coercive measures, it is fundamental prerequisite that a criminal investigation is initiated, but there exist some significant exceptions to this. There are also rules about who has the right to provide for the seizure, the decision can be taken by a prosecutor, an investigator, a police officer or, in special cases, the court.

This thesis discusses the dress code during the Pitted Ware culture on the Swedish island of Gotland. Eight Pitted Ware grave-fields have been analyzed; only 74 skeletons have been identified with some sort of ornament that could have been attached to clothes. The grave-fields are rich in finds and in people nearly every age group is present. The analysis has shown that there are clear differences between the genders. The female always has some sort of seal tooth ornament around her waist and thighs.

This thesis takes its starting point in the 27 Chapter 1, section 1 of the Swedish code of judicial procedure, where the following is found:?objects reasonably presumed important to a criminal investigation or taken from a person through a criminal act or subject to criminal forfeiture may be seized?In this thesis we have investigated what kinds of problems occur when the seized object is part of an investigation of IT-related criminality. We have used methodological investigations of Swedish laws, legal usage, and the preliminary work with laws. Further have three interviews been made with different actors affected by or involved in seize of objects. These persons were a police officer, a public prosecutor, and a person whose object has been seized.The result we present is that there exist three kinds of problems related to objects that are seized within the demarcation of this study.

In this study, six teachers have been interviewed about their vision and teaching of reading comprehension, both for pupils who has cleared the reading code and those who have not. The aim is to illustrate if teachers in middle school spend time to exercise reading comprehension, or if this is left to the Swedish teachers. Thus only according to the subject Swedish, the students are entitled to be given the opportunity to develop reading strategies.The interviews are semi-structured based on qualitative research. The informants are three teachers of Swedish and three teachers of other subjects. Two different interview guides were used containing three questions.

Bakgrund: Efter ett flertal större bolagsskandaler runt om i världen har en förtroendekris skapats på kapitalmarknaden. För att återskapa förtroendet har flera nya regler och rekommendationer instiftats som internationella börsbolag nu krävs efterleva. Ett led i de nya rekommendationerna är att noterade bolag i USA och England skall inrätta revisionsutskott. I dessa länder är det styrelsen, som i stor utsträckningen är anställda av bolaget, som utser revisorerna. Instiftande av revisionsutskott utgör därmed en säkerhet mot att företagsledningen skaffar sig obehörigt inflytande över revisionen.

The aim of this Master?s thesis is to examine three library weblogs to evaluate how they are used and what type of information the libraries publish in these specific weblogs.The following three questions are the basis of this study:? What is the content of the weblogs?? How is the weblog used as a tool by the libraries?? How is the interaction between the library and the readers of the weblogs presented regarding the comment function?The method that has been used in this study is content analysis and the code units have been created during the process. It is mainly a qualitative analysis but it does also contain quantitative elements. With the content analysis, 21 different themes where cut from the three weblogs. These themes where then put into the model of the local library profiles worked out by Marianne Andersson and Dorte Skot-Hansen.

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.
