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).

This essay examines how art could be used to bring forth and clarify the Catholic doctrines of purgatory. The research questions are: ? How are the Catholic Church?s doctrines of purgatory illustrated in art? ? How can the paintings affect the viewer and his/her notion on how to shorten the time in purgatory? How can art itself be used as a tool to achieve that goal? The timeframe of the chosen paintings is mainly 14th to 16th century but an overview of how the purgatory has been illustrated after that time until the present is also given. In order to answer the first research question, a painting from the 14th century has been analysed, using a method inspired by Patterns of Intention - a theoretical framework formulated by Michel Baxandall. A reception theoretic perspective according to Kemp, is used on a painting from the 15th century to answer the second research question. The results show that purgatory is illustrated as fire and the souls are depicted as living people, despite that a spiritual condition is visualized. The viewers at that time found the descriptions frightening, but the paintings also revealed ways of being granted indulgences, that is shorten-ing the time in purgatory. These ways were praying, making pilgrimages and giving alms.

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..

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..

Formålet med denne undersøgelse er at undersøge om svenske gymnasieelever føler sig som en del af et nordiskt sprogfællesskab. Dette gennem at undersøge hvilken interaktion eleverne har med de nordiske sprog, hvilke sprog de mener at de forstår, hvad læreplanen siger om Norden og de nordiske sprog, samt at undersøge elevernes holdning til de nordiske sprog. 20 elever opdelt i fire fokusgrupper er blevet interviewet, og læreplanen for grundskolen och gymnasiet, samt læreplanen for faget svensk, er blevet analyseret. Læreplanen opfylder ikke de mål og avtaler som findes omkring den samnordiske sprogpolitik, og resultatet fra samtalerne med fokusgrupperne viser at eleverne først og fremmest kommer i kontakt med de skandinaviske sprog, hvilket viser at fællesskabet primært handler om et skandinaviskt sprogfællesskab. Eleverne opfatter norsk som et smukt og let sprog, hvorimod dansk anses være et grimt og svært sprog.

In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Följande rapport beskriver teori, metod och resultat av ett examensarbete vid Luleå Tekniska Universitet utfört i samarbete med Light My Fire AB. Företaget tillverkar produkter som används av människor i hela världen och som ger användaren ett leende på läpparna. En produkt som har saknats i sortimentet är en vätskebehållare och flera återförsäljare världen över har frågat efter just detta. Målet har varit att ta fram en multifunktionell vätskebehållare som ska passa in i Light My Fires befintliga sortiment och få plats i företagets produkt, LunchBox. Projektet började med en grundlig benchmarking för att ta reda på vilka olika typer av vätskebehållare som finns.

This essay is from a student at the cultural science program in Karlstad University. The essay in Culture studies deals about the history use and about the cultural-historical values on buildings. The buildings are from a certain area called the neighborhood Almen and have in the past been threatening many times of demolition. The neighborhood Almen buildings survived a huge city fire back in the 19th century. Since then the buildings has been known as a memory and by the inhabitants and as the oldest part of the city left.

This essay is about the burial rites in the passage graves of Falbygden, Västergötland. My questions were: Can the burial ritual be understood by comparing the material culture inside and outside the tombs? What kind of grave offerings did the dead have? Most peculiar are all these beads of amber, what kind of meaning did they have? Was the position of the body a part of the ritual? The time period is the middle Neolithic.I selected four passage graves to investigate: Hjälmars rör (Falköping 3), Rössberga (Valtorp 2), Näs sn 7:2 Kvättak 5:1 and Frälsegården (Gökhem 94).My conclusion was that there are differences between the material culture inside and outside the tombs. Outside the ritual includes fire, inside the material culture are not burned. The material culture outside is more dominant than the finds inside, although the beads of amber are only represented inside and dominates the findings inside.

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

Vid årsskiftet 2009-2010 slogs Norrköpings brandförsvar samman med Linköpings räddningstjänst och bildade Kommunalförbundet Räddningstjänsten Östra Götaland. Sammanslagningen innebar att det nya förbundet förfogade över totalt 12 stationer i de båda kommunerna, varav 4 st. är heltidsbemannade och de andra 8 är deltidsbemannade. Rapporten avser att ge en bild över samtliga stationers täckningsförmåga (serviceområde) inom ett antal olika tidsintervall samt att ge en helhetsbild över hur väl de två kommunerna täcks in. Arbetet skall även svara på vilken station som skall fungera som andra insatsstation vid händelse av att primärstationen är upptagen vid inkommande larm eller när primärstationen behöver assistans vid större insatser.Räddningstjänstens arbete regleras av ett antal lagar och bestämmelser, bland annat lagen om skydd mot olyckor (LSO) som syftar till att i hela riket skydda människoliv, egendom samt miljö.

I dagsläget har räddningstjänsten i Luleå kommun brandstationer i Luleå centrum, Gammelstad och Råneå som ska kunna undsätta cirka 75 000 invånare på 2110 kvadratkilometer stor yta. Inom en snar framtid behöver investeringar utföras, antingen i form av en ny brandstation, eller genom en upprustning av den befintliga i Luleå centrum. Samtidigt står verksamheten inför nya utmaningar då kommunen har tagit fram ett arbetsunderlag, Vision Luleå 2050, för befolkningstillväxt och utveckling. Därför har räddningstjänsten i Luleå, på uppdrag av räddningsnämnden, påbörjat en arbetsprocess som ska utreda framtida brandstationsplacering i Luleå kommun. I denna studie belyses frågan med avseende på responstid och täckningsgrad.

This is the final documentation of the basis that can be the foundation of how to solve theproblem with leaking hydraulic oil in a shoe press at the company Albany InternationalAB in Halmstad, Sweden.The project has been performed at Halmstad University as a degree project commissionedby Albany International AB. The purpose of the degree project was to find a way ofdetecting the hydraulic leak of a shoe press. The reason is that the shoe press runsunattended during nights and weekends, this can cause an extensive decontaminationwork and production stop if leak. The hydraulic oil could be leaking in large amounts orslowly as a fine mist. The development of a working system that can detect a hydraulicoil leak and stop the machine before a large amount of hydraulic oil leaks out wouldconsiderably reduce the cost of the decontamination work.
