Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

Crowdfunding is described as a facilitator for creative entrepreneurs in their gathering of funds for projects. This bachelor?s thesis  aims at finding differences in communication components found between successful and unsuccessful crowdfunding campaigns on one of the most popular platforms, Kickstarter. Through a quantitative content analysis and a rhetorical analysis of literary topoi this study suggests that there are apparent differences in usage of titles, text, visual expressions, rewards and in themes of preparation, humility as well as quality. The findings we present conclude that a campaign with a title consisting of eight words and one punctuation are more likely to succeed than other.

Joakim Schyman, 2009. Den gotländska vikingatida bebyggelsens rumsliga placering ilandskapet - En empirisk detaljstudie av Hemse socken (The spacial distribution of the VikingAge settlements on Gotland ? An emperical study of remains from Hemse Parish.)This essay investigates whether a relation between Viking age graves and Viking agesettlements in Hemse parish can be found. This was done by using database information onViking age findings, such as silver hoards, phosphate levels and location of graves in Hemseparish. Literature and maps were also used.

Partnering is a collaboration method where the contractor and the client work together, based on a mutual trust towards each other and with a common goal for the project. The method originates from the United States where it was early adapted by the U.S. Army Corps of Engineers. It later spread internationally where the United Kingdom and Denmark were early in Europe to see the potential with partnering, to help aid with the issues they were having where construction projects kept running late, going over budget and lacked in quality. By using partnering you can achieve a shorter building time, improved work relationships and enhanced efficiency and cost effectiveness.

Flustret is a restaurant and an entertainment place situated by Svandammen in Uppsala. It all began in 1842 as a café serving coffee, tea, chocolate and pastry. During the years the building has had numbers of different owners. The owners of today are running Flustret in a same friendly spirit that has been characteristic from the beginning. The buldings history is now approaching an age of 165 years. Throughout the years different historical layers have been placed on top of each other, leaving a layer of patches.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

It is important for firms to continually develop their offerings as the business landscape develops in order to sustain their competitiveness (e.g. Schumpeter, 1934; Ansoff, 1979; Porter, 1985; Trott, 2012). In a context of globalization, rapid technology development and changing customer needs, the paper packaging industry is urged to enhance its product development activities (Hansen & Niskanen, 2007; Björkdahl & Börjesson, 2011). However, there is little research about paper packaging firms? product development processes (ibid).

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..

ABSTRACTThe privatization of pharmacies in Sweden took place in 2009, in part with higher availability of medicines as justification. For a good adherence, the patients needs a good availability of medicines from pharmacies. The aim of the study was that two years after the pharmacy reform study older people?s opinions on drug supply and pharmacy services, and which pharmacy chains they know about and use. The method used was a quantitative cross-sectional study and was conducted using questionnaires.

Blodtrycksmätning är en viktig del i en sjuksköterskas arbetsuppgifter och då både manuell och digital blodtrycksmätning idag förekommer parallellt inom svensk sjukvård syftar denna studie till att undersöka om det finns någon skillnad mellan de uppmätta resultaten i dessa mätmetoder och beskriva denna eventuella skillnad. Undersökningen genomfördes på en kärlkirurgisk avdelning på ett sjukhus i södra Sverige under hösten 2009. Populationen bestod av 38 inneliggande patienter som följdes upp med totalt 65 blodtrycksmätningar. För att utföra undersökningen tillämpades cross-over design med kvantitativ ansats. Resultaten visade skillnader mellan de två mätmetoderna då den digitala metoden uppmätte högre blodtryck än den manuella. Digital blodtrycksmätning visade genomgående högre mätresultat jämfört med manuell metod.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.
