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.

Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.

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.

This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences. The application is supposed to be run as a simple executable file with flash embedded.

This essay is a study of the market strategies and situations in the telephone business. Our problem was to examine the telecom companies´ strategies to stay competitive and cope with the new VoIP technology. We chose to do a qualitative study and four telephone interviews were made with Swedish and Dutch companies. We investigated three different categories of companies in the market; industry leaders, cable companies and broadband companies to get a broad view of the market. The theory chapter is based on different strategies that companies have to or can apply to get ahead, stay or survive in a hypercompetition.

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.

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

In this paper we have examined why seniors do not use e-business to the same extent as other age groups. Seniors belong to the age group that, according to statistics from Statistics Sweden (SCB) in 2011, utilizes e-business the least in relation to the number who use the internet. To understand how seniors reason and perceive the possibility to shop on the internet, we have conducted four interviews with people from 65 years and older. We have let the respondents answer questions regarding utility aspects, e-business interfaces, general shopping habits, risks, and whether or not they usually shop online. We also found out how seniors reason when they sell products and services.

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.

During our formative years, technology has always had a natural part of everyday life, and for us technology has never been particularly gendered. If this depends on the climate and the attitude of our homes, ourselves, the combination of both or something completely different is a question we have asked ourselves at times. But our approach to technology does not seem as obvious to all women, and today the IT industry is heavily dominated by men. This has meant that we have asked the question whether there is any underlying reason why so few women opt for IT courses? Is there a link between how different IT organizations profiles and the prevailing gender ratio? The purpose of this study is to investigate whether there is any connections between how IT organizations are related to gender issues and how the structures, attitudes and gender actually looks like in the IT industry today, and how this can be seen in their branding efforts.

This study examinates technology's traumatic impact on the male subject in The Atrocity Exhibition by J.G. Ballard. In my analysis I show how the protagonist uses a fetischistic strategy in order to make sense of the trauma that technology embeds. Paradoxically it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system.

This report describes a thesis done at the Jönköping University of Technology. The aim of this thesis was to create conditions to optimize an existing automatic electrostatic coating system by changing the technology for dispensing lacquer. To select the technology, a study of different dispensing techniques carried out which concluded that the piezoelectric membrane and electrostatic atomization are the most interesting techniques.In order to perform tests with dispensing techniques a demonstrator has been optimized. The controller and PC software of the demonstrator has been programmed to be able to send out PWM signals that control the dispensers. An adapter card was designed to control the piezoelectric membrane and a steering link to the electrostatic atomization has been developed for PWM signals up to 500V.The work has laid ground for a demonstrator where further testing of the dispensing technologies can be performed..

This study focuses on the transfer between a product-oriented to a service-oriented perspective regarding marketing activities in companies due to the development of information technology. It illustrates how this very transfer has been, and can be, contemplated through the eyes of organizations working with marketing in a digital world on a daily basis. Technology has turned several industries - their price-setting, communication channels and supplying possiblities - upside-down. This turnpoint brings out a new way of observing and working with marketing. Therefore, we find it interesting to gain a better understanding of how actors within industries where the turnpoint is a fact observes marketing, and how this service perspective can be seen in their various organizations and daily.
