The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..

This paper describes the redesign of a site (Kolonn.se). Some of the problems with the site were a lack of structure and a design that was unclear both visitor and search engines. The site now has a new design and structure that has been taking form in Axure prototypes that has been tested and applied into WordPress. The results are a site with a new main menu, new graphic profile and logo. Also SEO-adapted content such as correctly structured headers, meta tags, descriptions and key words that has been implemented in the content.

To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Problem solving is a big part of design, however a lot of emphasis is put on creativity in research related to the effects of stress. Research has shown that the amount of stress we feel affects idea generation. Stress may also affect the ability to solve problems, however the researchers don?t seem to agree about what the effect of stress actually does.The study was made through experimental sessions where the respondents were asked to solve 4 matchstick puzzles of similar difficulty. Depending on their outcome they experienced more or less stress.

Detta examensarbete är ett projekt som utförts på uppdrag av Sunnex Equipment AB. Syftet var att utveckla nya ledade armsystem till en medicinsk belysning för att ersätta de tre armsystemen som marknadsförs av företaget idag. Det var även önskvärt att projektet resulterar i ett förslag på utformning av ett tillhörande lamphuvud. Fokus har varit design och ergonomi. Arbetet har följt en strukturerad produktutvecklingsprocess som inleddes med informationsinsamling genom användarstudie, intervjuer, konkurrensanalys och litteraturstudier.

The project has been oriented for development of fixtures to ateljé Lyktan to provide a more efficiency line. In the year 2012 the company invested in a new coating booth, which leads to opportunities to upgrading the fixtures and also new design. The request is to minimize the area for storage of fixtures, and therefore should fixtures be designed to apply as many articles as possible The priority of products that fixtures have development to has been products that are most frequently coated and new products that don?t have any fixtures. The product families that the project has been having focus on is TIME and FOVEA with RONDO.

This is a report for a bachelor degree thesis in electronics at Umeå university. The target was to design a fully functional PCB-layout and then solder components to it. In order to do that I had to first proofread a schematic of the system to find things that were not correct and correct them. The project is a cooperation between the author and the company Calmon Stegmotorteknik. During the whole project the people at Calmon supported the author with the appropriate knowledge to complete the tasks.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

Webbdesign är ett hantverk med potential till oändlig variation och oräkneliga möjligheter, men det är även en process styrd av standarder och förhållningssätt för att optimera resultatet för slutanvändaren. Begrepp så som user experience och framför allt user experience design har i och med utvecklingen blivit allt viktigare aktörer inom webbdesign. Samtidigt som de underlättar i utvecklingsprocessen genom att diktera hur design bör utformas, skapar de inte också då begränsningar av potentialen för webbdesign? Antalet variationer och möjligheter minskar drastiskt när webbdesigners anpassar sig efter dessa standarder.Den här undersökningen syftar till att utveckla nya metoder och strategier för att främja innovativ webbdesign och undersöka hur modebranschens konstanta strävan efter innovation skulle kunna inspirera och kanske till och med förändra webbdesign utvecklingen. Genom att bryta ner, analysera och sammanfoga designprocesserna för haute couture och webbdesign skapas en designmetod som ger medvetenhet i designval och hjälper att ifrågasätta standarder samt att undersöka alternativa lösningar.

Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.

In 1999 the Swedish Parliament decided about 15 environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

Ian Thompson menar att man, vid gestaltning, bör ha som mål att slutresultatet ska inneha höga värden av ekologiska, sociala och estetiska kvaliteteter. Detta benämner han som trivalent design, något som han menar att generellt innebär bättre design än uni- eller bivalent design där endast en respektive två av dimensionerna ovan tas i beaktande. I detta arbete är syftet att ta fram ett programförslag för ett bostadsområde i Södra Lillängen i Mariehamn och samtidigt undersöka trivalent design som hjälpmedel för landskapsarkitekten. Frågeställningen som använts är hur ekologiska, sociala och estetiska dimensioner kan bevaras och gestaltas vid en exploatering av Södra Lillängen. Arbetet har delats upp i en förstudie och en programförslagsdel. Förstudien bestod av en inventering, en art- och habitatsundersökning och en analys. Under inventeringen studerades området och omgivningen för att ta reda på vad som fanns på och omkring platsen idag.
