In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..

Under de senaste åren har barnklädesbranschen och dess aktörer upplevt en kraftigt ökad efterfrågan och utbud på marknaden. En högkonjunktur och en trend där förstföderskorna är äldre gör att barnfamiljerna har stabilare ekonomi. Konsumtionstrender visar även ett ökat fokus på familj och personlig identitet där småbarnsföräldrar gärna spenderar pengar på barnkläder. Dessa fenomen har bidragit till att det finns stora möjligheter för små barnklädesmärken att etablera sig på marknaden. En marknad där det även råder hård konkurrens och stora modejättarna drar stora fördelar då de kan konkurrera med pris.

Det finns en låg grad av mångfald i svenska börsbolagsstyrelser. Enligt omfattande studierförbättrar ökad mångfald en grupps kreativitet och prestation. Syftet med studien är attanalysera hur mångfaldsmåtten åldersspridning och kvinnonärvaro i svenskabörsbolagsstyrelser kan påverka vd:s position, eftersom grunden för ett framgångsriktjämställdhetsarbete ligger i ett företags ledningsgrupp med vd som främsta representant.Studien inkluderar samtliga kvinnor som varit vd:ar på börserna Nasdaq OMX Stockholmoch NGM Equity och en jämförelsegrupp av manliga vd:ar som haft förtroendeperioderunder liknande omständigheter som kvinnorna. Resultatet visar ett samband mellan kvinnligstyrelsenärvaro och förlängd förtroendeperiod för vd:ar, i synnerhet för de kvinnligavd:arna..

The aim of this text is to study how sectional managers in the care of the elderly work so as to promote basic human values. Semi-structured interviews generated qualitative data from five sectional managers. A hermeneutical approach was applied for interpreting the interviews. The result shows that the respondents are conscious of the fact that it takes a lot of long term work before a change in current procedures will happen. Also, the common everyday principles of work and basic values will continue to be part of the care of the elderly.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

This study has been conducted in order to determine the existence of predictability for the Stockholm stock exchange. With this purpose the random walk theory has been raised against the theory of mean reversion in order to determine which theory is the most substantial. Data has been collected from Nasdaq OMX Nordic and furtherly been processed using the statistical software EViews. Swedish listed companies? daily share values between 2000-2014 have been analyzed using two tests; an Augmented Dickey Fuller test and a Variance Ratio test.

In an organizational change process, motivated employees are considered an asset. Work motivation can both be seen as situational and as a stable individual characteristic. The present study attempts to investigate how the employees at the Social Insurance Office in Scania experience the present organizational change by focusing on work motivation and well-being. Both questionnaires and interviews were adopted to examine the area of interest. Findings indicate that the organizational change is considered chaotic but necessary by the employees.

Social media has changed the way that corporations can communicate with their target groups. Instead of using one?way communications that has been significant for traditional massmarketing, social media has given corporations the possibility to truly interact with their clients and through the interaction build strong relationships. The interaction is an ideal process for corporations to create brand associations and strengthen their brand equity to position their brands in the minds of the consumers. But social media is also a devious medium because everyone are invited to contribute their opinion and news travel fast in social atmosphere, success and crisis can appear fast and out ofnowhere.

A high degree of urbanization with growing cities has raised a need of transforming closed landfill sites for giving them new uses. This study aims to investigate how old landfills can be re-used, what has lead to the new uses, and for what and whom the transformed site will be an asset. The method used is a case study of four different landfills in Stockholm county, Sweden. The case study is analyzed in the light of former studies regarding re-use of degraded urban areas, so called brownfields, and in particular studies and reports of landfill re-use. The result indicates that old landfill sites is identified as an area with possible values if transformed properly, in the case study area especially as green structure and recreation areas.

This study examines implementation from national law in to local practice in the district of Kalmar to assure newly arrived immigrants orientation in civics. The study takes its starting point in Lipskys theory about street-level bureaucracy.  Questions that are discussed are about how  the education is understood by refugee?s coordinators, civic communicators and the new immigrates, how the organization has been and what role the demography and economic structures has played for the organization. It is a case study where interviews and enquete has been used.

The aim of this study is to examine whether the two factors SMB and HML in the Fama-French Three Factor Model proxy for default risk. The study is based on companies noted on the Stockholm Stock Exchange between 2003 and 2008. These companies are used to create the factors SMB and HML, as well as a default risk factor we call RMS. In a first set of regressions, we examine the explanatory power of the original Fama-French model on a set of portfolios consisting of Swedish companies of different size and book-to-market ratio. The default risk factor RMS is then added to the original Fama-French model.

With the fast development of Internet and the e-commerce during the last decades, retailers are now introducing online stores. This has been adopted as a common strategy within the industry and the phenomenon seems likely to increase over time. Theory based on brand extension is used in this study to explain the effects on brand attitude and the link with willingness to pay when a traditional retailer introduces an online store. We execute an experimental study in order to investigate the effects where we use the offline- and online channel as well as two brands with different strengths as independent variables. Results show that brand attitude and its link to willingness to pay transfers to the online channel.

Syftet med studien var att undersöka om en matematisk diagnos kan användas för att bedöma hur likvärdigt betyg sätts. Studien visar att diagnosen indikerar skillnader i likvärdighet som ligger i linje med tidigare forskning. En mer detaljerad undersökning där diagnosen jämförs med nationella prov skulle ge ett säkrare svar angående diagnosens tillförlitlighet.Diagnosens förmåga att förutsäga elevernas betyg i första matematikkursen i gymnasiet var god. Sambandet mellan diagnos och gymnasiebetyg var starkare än sambandet mellan diagnos och grundskolebetyg. Detta kan ha flera orsaker: (i) gymnasielärarna som konstruerat diagnosen har endast tagit med uppgifter som sammanfaller med första? gymnasiekursen, (ii) grundskolor sätter betyg på olika grunder, (iii) elevernas matematikkunskaper förändras över sommarlovet..
