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).

Motivation är en viktig komponent för att en person ska kunna genomföra en uppgift. Men hur personen handskas med uppgiften beror på vilken typ av motivation denne drivs av och i vilken grad. Tidigare forskning har visat att exempelvis stress har en negativ påverkan på motivation. Syftet med denna studie var att undersöka hur kön, ålder, antal arbetade år och stress är relaterad till inre och yttre motivation hos poliser i yttre tjänst. Deltagarna bestod av 142 personer, varav 36 stycken var kvinnor.

Syftet med detta examensarbete var att undersöka vilka faktorer som påverkat acceptansen hos användare, inom den kommunala verksamheten, vid införande av ett datoriserat system. Med acceptans menas att användarna ska kunna utföra sina arbetsuppgifter på ett bra och lätt sätt. Studien har gjorts utifrån användarnas perspektiv.Genom att genomföra en intervjuundersökning på ett flertal kommuner där användarna använder systemet Vabas/Duf, har undersökts hur användarnas upplevda acceptans påverkas av faktorerna delaktighet, användbarhet och lättanvändhet, vid införande av ett datoriserat system. Delaktigheten vid införandet av ett system innefattar även information och utbildning.Resultatet från undersökningen visade att delaktigheten ökade användarnas acceptans. Ingen avgörande slutsats kunde däremot dras mellan acceptans och faktorerna användbarhet och lättanvändhet, då resultatet från de båda grupperna inte visade någon märkbar skillnad..

Archaeological findings show that ski manufacturing goes back thousands of years in the Nordic region. There is a wealth of literature and film that deals with the subject, but it can be difficult to get an overall picture of how a specific type of traditional ski has been made. The starting point is the documentary "Skidmakaren i Gielas", where the viewer can follow Alfred Israelsson as he makes a pair of skis out of birch wood. However, the documentary lacks important information about how the skis are actually manufactured. Length, width and certain working steps are disclosed.

The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

Enligt principal-agentteorin bör incitamentsprogram vara utformade så att den verkställande direktören får incitament att utföra de handlingar som ökar aktieägarnas nytta. Detta kan ske genom optionsprogram. I denna uppsats undersöks huruvida institutionellt och utländskt ägande samt utländska styrelseledamöter driver fram optionsprogram i svenska börsbolag. För att utforska detta har vi samlat in datamaterial från 49 svenska företag noterade på Nordic Large Cap och sedan estimerat logitmodeller. Vi får inget signifikant resultat för vare sig institutionellt eller utländskt ägande.

Companies and organizations recognize the importance of collaboration to develop responsibility and ability of change in the workplace. The concept of collaboration was a relatively new idea in business in the late 1980s. In a Nordic context, collaboration is a traditional approach that companies use successfully for competition, survival and development. Collaborative organizational efforts cover management of committed people who can help companies achieve flexibility, customer loyalty, innovation and economic success on a challenging and competitive market. Many theorists believe that collaboration is the key to integrating technology, financial competence and innovation.

Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

SAMMANFATTNING Mitt examensarbete utgör ett led i Nordiska Genbankens (NGB) uppgift att skapa en nordisk s.k. ?core collection? av rabarber, Rheum rhabarbarum L. Samlingar finns även i våra nordiska grannländer Norge, Finland, Danmark och Island. I Sverige har ett insamlingsarbete av rabarber pågått under åren 2002 och 2003 för att komplettera en äldre samling.
