Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

I denna uppsats har filmljudet i krigsfilmerna Apocalypse Now och Saving Private Ryan undersökts. Detta har gjorts för att försöka bidra med ökad förståelse för filmljudets användningsområde och funktioner, främst för filmerna i fråga, men även för krigsfilm rent generellt. Filmljud i denna kontext omfattar allt det ljud som finns i film, men utesluter dock all ickediegetisk musik. Båda filmerna har undersökts genom en audio-visuell analys. En sådan analys görs genom att detaljgranska båda filmernas ljud- och bildinnehåll var för sig, för att slutligen undersöka samma filmsekvens som helhet då ljudet och bilden satts ihop igen.

This bachelor´s thesis analyzes the video game Red Dead Redemption and the historical use of the environment and atmosphere in the game. The theory and method used is media research and social memory studies. Two questions were asked: how does Red Dead Redemeption convey and produce the historical environment and the historical atmosphere. Furthermore subqueries/criterias were used to help answer the main questions.The analysis was divided into two parts, the first part we analyze and discuss the games historical environment and the second part analyzes and discusses the historical atmosphere of the game.The conclusion is that both the historical environment and the historical atmosphere is present in the game through picture and sound, the text only works as a guide. The picture and sound live in a symbiotic relationship and depend on each other to fully immerse the player to the game.

Can coercive care be justified against drug and alcohol addicts or should treatment be offered on a strictly voluntary basis? This was one of the central questions debated in Sweden during the 70's when the development of a new social legislation, The Social Services Act (Socialtjänstlagen), took place. The first aim of this thesis was to analyse whether the arguments that were presented both in favour for and against coercion were sound. To achieve this, a method for analysing arguments was employed, where a sound argument is defined as acceptable, relevant and adequate. The analysed material consists of both official government reports and books of influential debaters.

Denna slutreflektion beskriver arbetet med att designa soundtracket till filmen Ont blod, en novellfilm som spelades in på Gotland hösten 2010 av Andersson/Wilén produktion. Vårt arbete har varit postproduktionen av allt ljud, inklusive musikkomponering. Syftet med arbetet var att testa och jämföra de två metoder av surroundmixning (direct/ambient och direct-sound all round) för film som Holman (2008) beskriver, för att sedan välja den som passar vår produktion bäst. Reflektionen är skriven i två delar. Den första delen handlar om produktionen i sin helhet och om projektplanen.

We read different kind of texts every day. We can for example choose to read a book or to watch a film. While we read we can receive and interpret texts. That?s means, for example, that we can have different envisionments about the drama and the film based on it. Based on Langer?s reception theory about ?envisionments?, I?ve wanted to examine and clarify the differences and similarities of envisionments between two texts.

Syfte: Rapportens syfte är att kartlägga om upplevelsen av ett rum kan förändras beroende på om och vilka ljud som spelas upp i rummet. Metod: I samband med en ljudinstallation på Plattan vid Malmö Högskola har rörelsemönster och beteende för Plattans besökare observerats. Dessutom har flera besökare besvarat en enkät. Resultat: Inga eventuella förändringar i rörelsemönstret eller beteendet för Plattans besökare kan ses som en konsekvens av ljudinstallationen. Det finns inte heller någon skillnad i enkätsvaren beroende på installationen. Slutsats: Resultatet ses som en konsekvens av bristfälliga forskningsmetoder. I rapportens slutsats bildas hypotesen att en installerad ljuddesign inte är en tillräcklig åtgärd i den undersökta typen av miljö.

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

Sit, Eat, Drink, Talk, Laugh ? Dining and Mixed Media, is an exploratory study of qualities in everyday life and challenges people to enjoy the qualities of mundanity. Seeking inspiration in ethnographic studies, field work was conducted in domestic settings, returning an extensive body of material to work from. The study challenges people to absorb the moment, reflect and enjoy, rather than pacing through a lifetime, with a constant focus on the future instead of the present. This work takes a starting point in food and dining as a social activity, where interactive sound and a reference to online social media is explored through two interventions.

Internet's entry into our home has changed our communication capabilities. As a result more and more services in the digital world are available. Besides e.g. shopping, gaming and general information, different social networks now offer preventive and therapeutic health-oriented services. When being asked by several young people, with whom I have been working in a clinical setting, to offer conversations over the Internet that enables both to see and to hear each other in real time, I decided to conduct a pilot study which is presented in this paper. The aim was to investigate the feasibility of offering supportive therapy using video calls over the Internet.

Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.

Metoder och system för mätteknik får en allt större betydelse för moderna tillverkningsföretag. Allt fler företag har insett det strategiska värdet av en förbättrad kvalitetsuppföljning för att minimera kostnader på grund av kvalitetsbrist. Syftet med denna rapport är att ta fram en strategi för standardisering av kontrollmätningen vid den nya typ av mätplats, en Q-plats, som ställts upp inom avdelning DXMH vid Scania Transmission. Q-platsen ger möjligheter för operatörerna att i större grad själva genomföra kontrollmätningen i närheten av produktionslinjen. I rapporten analyseras först Q-platsens funktion utifrån en studie av Scania Transmission DX, dessutom redovisas fallstudier på andra avdelningar inom Scania och vid andra tillverkningsföretag.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.
