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..

The aim of this bachelor thesis is to find out how a number ofhospital librarians look at child and youth patients' reading and itspossible role in a mental and physical healing process. We alsoinvestigate the knowledge, strategies and thoughts the librarianshave on bibliotherapy.Qualitative interviews have been used and seven librarians, at twodifferent hospital libraries with children's and youth activities, wereinterviewed during November and December 2011. The analysis isbased on one theory; we use Sten Furhammar?s model whichincludes four different categories of reading.We can see, according to the librarians? answers, that the mostcommon function of the patients? reading can be explained throughtwo of Furhammar?s categories. Our respondents believe that thepatients mostly read to relax from heavy thoughts and situationswhich can be connected to the category impersonal experiencereading.

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.

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

Choosing a new plastic material for a container includes several different steps. In this case,the Finnish company Hackman needed a new type of packaging material for theircutlery- and kitchentool series »Hackman tools«. The project was carried out in cooperationwith the design agency Ytterborn & Fuentes, which has Hackman as a client.Several different demands were put on the material in order to fulfill as many of the clientswishes as possible. The most urgent problem with the existing container was the difficultysfor the customer to clearly see the contents in the container. Because of this problemthe customer tried to open the container in the shop.

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.

The purpose of this paper was to look into how the individual has been portrayed in the different curriculums for Swedish compulsory school from the 60?s to the 90?s. This was done in order to see what type of discourse ?monocultural- multicultural- or intercultural- the understanding of the individual has led to.The purpose was divided into five questions: Who is the individual in the curriculums? How is the individual portrayed in relation to education in the curriculums? How is the individual portrayed in relation to society in the curriculums? What type of discourse - monocultural- multicultural- or intercultural- is mirrored in the different curriculums? Is it possible to see tendencies in the discourses that lead closer to, or farther away from, an intercultural perspective? The material that was analysed consists of four different curriculums: Lgr 62, Lgr 69, Lgr 80, and Lpo 94.The method used was a discourse analytic approach based on the theory of social constructionism. The answers to the questions asked were structured with the support from definitions of monocultural discourse, multicultural discourse, and intercultural discourse, derived from Pirjo Lahdenperäs (2008) descriptions of different organizational cultures.The main conclusion drawn from this analysis was the fact that the intercultural discourse about the individual has not been obtained.

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.

One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

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.

Functional Magnetic Resonance Imaging, fMRI, can be used for analyzing brain activity in subjects performing language tasks. The purpose of this study was to develop aphasia-friendly information adjusted to aphasic subjects participating in fMRI studies. The objectives were to investigate if adjusted information was important for the ability to perform language tasks and if the information could be used for different types of aphasia.Sixteen aphasic subjects participated in the study, six of these underwent fMRI. The participants varied in grade and type of aphasia. They had Swedish as their native language and were aged between 26 and 89, mean 57.
