In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

An evaluation: how have the goals of ?Vårdkedjeprojektet? been implemented at the treatment centre of RällsögårdenThis evaluation was commissioned on behalf of the treatment centre of Rällsögården. The aim of this study is to evaluate how the goals of ?Vårdkedjeprojektet? (VKP) have been implemented in the institutional care at the treatment centre of Rällsögården. This study was focused on the following questions: a) how is the function ?internal coordinator? experienced by staff at Rällsögården, b) in the function of internal coordinator what aspects are thought of as effective/non-effective concerning the cooperation with ?external coordinators? and contact with clients and staff, c) how is Vårdkedjeprojektet and its treatment approach ?Community Reinforcement Approach? (CRA) experienced by coordinators, clients and staff and d) how well is the aftercare functioning for clients who have finished their treatment at Rällsögården, and still participate in VKP?The choice of research method was triangulation; a combination of qualitative and quantitative methods.

The survey was conducted based on a qualitative method and empirical data gathered through semi-structured interviews with employees in the social services. The result shows that there is a need for more and specific education for families receiving unaccompanied children. It is motivated by the needs and conditions that are often common for this group.

Det finns ett ökat intresse för företagsförvärv och huvudanledningen till det är att företag vill skapa synergieffekter. Många företag misslyckas med att göra företagsförvärv och tidigare studier visar på svårigheter vid integration. Bristande anpassning av strategi och ledarskap har inte gett förklaring till varför företag misslyckas med integrationer. Mänskliga och kulturella aspekter har visat sig vara relevanta att studera för lyckade integrationer.Studiens syfte är att öka förståelsen för institutionella mekanismer vid integration av företagskulturer vid företagsförvärv. Ett delsyfte är att identifiera framgångsfaktorer för en lyckad integration av företagskulturer vid företagsförvärv.

Denna studie syftar till att undersöka hur skolkuratorer i svenska grundskolan upplever sin arbetssituation. För att ta reda på detta har vi använt oss av en kvalitativ metod där vi intervjuat fyra skolkuratorer som alla är verksamma i ett område i Mellansverige. Vi valde att i intervjun fokusera på upplevelsen av krav, kontroll och stöd utifrån krav-kontroll-stödmodellen som teoretisk utgångspunkt. Denna modell anses kunna förklara vilka kombinationer av krav, kontroll och stöd som bidrar till en stressig arbetssituation samt vilka kombinationer som motverkar en stressig arbetssituation. Resultaten i denna studie visar att skolkuratorer upplever höga krav i form av en hög arbetsbörda vilket är det som bidrar till stress.

The development of our time, is due to great progresses in technology and an enormous ex-plosion of knowledge, has lead to an increased effort of our attention as a result of a boundless torrent of information . Higher productivity and efficiency in our workplaces and homes crea-tes fewer opportunities for rest, leading to a community where stress has become a national disease. Recreation is an important part of our lives in order to be able to deal with stress and is now considered to be an essential resource when it comes to sustainable development. Green spaces are therefore today viewed to play a considerable roll for the national health. Nature has proven to have positive influence on man which leads to a decrease in blood pressure, an increase in power of concentration and lowered production of stress hormones.

There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.

Sustainability reporting in Sweden is a voluntary disclosure action for non-governmental companies. Since 2009 all state-owned companies must however publish a sustainability report according to GRI guidelines and with independent assurance statement. Three different sustainability reporting methods are primarily used: (1) Separate Sustainability Report, (2) Sustainability Report included in the Directors? Report, and (3) Sustainability Report forming part of the Printed Annual Report. The aim of this paper is to explore why some companies choose to publish a sustainability report and identify the motivational factors behind this decision, as well as attain an understanding for companies? choice of reporting method.

The purpose of this master?s thesis is to study an electronic reference service from a user perspective. By qualitative interviews with eight students the thesis examines their information behaviour, why and when they use the service, the user?s experiences of the service and the communication with the librarian. The users have all used the Swedish electronic reference service Fråga biblioteket ? Forskningsbibliotek.

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Kalmar Municipality has in 2008-2010 made an effort to educate managers on gender, with the goal of mainstreaming gender into public activities so that all citizens should feel safe in that treatment and services are designed and resources are distributed equally to both sexes living conditions and needs. The overall aim of this study was to examine whether the training effort has paid off, and how gender mainstreaming has been implemented in the different activities. We have used a qualitative approach, which we examined through interviews managers' approach to gender equality.Gender was generally described as an important issue of all respondents, and all were working to mainstream gender into their activities and workplaces. The results show that the operational and management needed clearer directives and strategies in their efforts to promote gender equality. Education was necessary because personal definition of gender may differ from the control contents of the documents.

Lyckebo farm is the original name of the four building big farm, where year 2000, the former farmer established Maglarp/ Lyckebo golfcourse on his land of culture. In 2007, new owners are approaching the Maglarps golfcourse with thoughts of expanding the business. A first step in that direction is to form the area of the entrance, the specific area the visitors are staying at before entering the actual golfcourse to play. The designproposal is inspired by the peasant garden history of southern Sweden during the nineteenth centuary. It also aims to satisfy the demands of function and usefullness of a golfcourse today.

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

Internal data bases areprotected by so-called ?Fire Walls?, ?Watch Dogs? and Virtual Private Networks.

This essay consists of a heuristic analysis of referents in the Swedish educational act, leaning on the methodological guidelines of discourse analysis. The overall aim of the essay has been to analyse in what way language in the educational act works as guidelines and law in relation to teachers? work. To correspond to this aim an openly structured questionnaire has been used, providing an empirical view of how teachers understand certain words, or referents, in the educational act. This empirical data has then been shaped to a spectrum view of the definitions of the referents showing a number of deductable facts, including the significance of the apparent use of institutional and professional language, which then have been viewed from two theoretical perspectives.
