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.

Befolkningen i dagens samhälle blir allt äldre. Många individer drabbas av någon typ av demens, exempelvis Alzheimers sjukdom, då denna sjukdom är starkt knuten till hög ålder. En demenssjukdom för med sig många svårigheter, däribland drabbas minne, språk samt kommunikation. I Sverige idag finns många yrkesgrupper representerade kring den som har insjuknat i demens men sällan finns någon som har djupgående kunskaper om de språkliga och kommunikativa svårigheter som en individ, till följd av sjukdomen får. I början av Alzheimers sjukdom är de språkliga förändringarna knappt märkbara men med tiden tilltar de språkliga svårigheterna.

The awareness regarding environmental issues is increasing and as a result a large number of products are eco-labeled. This enables the consumers to make enlightened environmental decisions when purchasing products. Eco-labeling is no longer for products only, but also for services like hotels. It?s difficult to determine what it actually means to eco-label a hotel and what kind of benefits it includes.

Superior Canal Dehiscence Syndrome (SCDS) is a newly described syndrome with symptoms including sound- and pressure induced vertigo, conductive hyperacusis and autophony. SCDS is caused by absence of bone overlying the superior semicircular canal and can be surgically treated. As the syndrome and surgical technique is new, it is of importance to study possible postoperative outcomes..

 The main purpose is to investigate the main fea-tures of the discourse in the social medias about the legal view on cimes and criminals.                                                The special questions that are investigated are:1)    What specific features characterize the discourse in the social medias?2)    What are the legal restrictions for the freedom of speech on the Internet?3)    What attitudes can you find among lawyers towards the discourse in the social medias?4)    Are there grounds for presuming that the discourse in the social medias can effect the judgement in a special case?         .

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

AbstractThe purpose of the study was to examine if manual signs used as support to spoken and written language can be a god mnemonic for learning of word-pictures. I performed my study as an experiment in which I made a Memory game with word-pictures. I played the game with the children twice. The first time, we played without manual signs and the second time I used sign as a support. I observed the children and noted the words they learned to read with and without the support of manual signs.

Detta arbete analyserar och exemplifierar initiativ för att skapa hållbara kollektiva odlingar på landsbygd. Arbetet undersöker hållbarhetsbegreppet och fördjupar sig i frågan om vad hållbara jordbruks- och livsmedelssystem kan vara. Främst studeras alternativa kollektiva odlingsmodeller som strävar efter att sammanföra konsument och producent, framförallt via CSA-kooperativ, Community-Supported-Agriculture. Även begreppet Civic Agriculture, CA, uppmärksammas då det beskriver ett odlingsengagemang som går bortom de enskilda kooperativen. CA innebär ett förhållningssätt och agerande som verkar för lokalt hållbara livsmedels- och jordbrukssystem, och som utgår från den lokala platsens behov och förutsättningar med hänsyn till dess ekologiska- och socioekonomiska kontext där den passiva konsumenten istället blir en aktiv ?matmedborgare?.I arbetet framkommer det att långsiktigt hållbarhetsarbete behöver få utgå från varje enskild människas situation, och baseras på lust.

In my story there are daily conflicts that occur around the boy Peter. I focus on the role of the educator and the preschool, on the grey area children, on the interaction with parents and on "fighter relation". I have during my work tried to see this dilemma from differentperspectives. I question my role as a teacher and recently become a preschool teacher. Peter has no diagnosis, but I have decided to proceed from emotional disorders and language difficulties..

The purpose of the study was to look into the subjects which the students express when they cry out to their recreation instructor, if there are similarities and differences in the subjects when they turn to their recreation instructor or when they instead turn to their teacher, which different roles and positions the students place their recreation instructors and the teachers in. I have used focused observations during three days in two different schools. Using the ideas of J.Butler on performative perspective, I´ve analyzed the way the students have positioned their recreation instructors and teachers through speech and actions. My conclusion is that students early on see hierarchical structures in school and help maintaining them..

The title, ?You simply must own your classroom?, is taken from a quote from one of my informants.After review of earlier research on how teachers handle their leadership in the meeting with disturbing pupils and which strategies they use to solve problems in the classroom, interesting questions developed. What experiences do teachers have of disturbing situations in the classroom? Which strategies do they use to solve the problems? What kind of support do the teachers consider necessary in teaching? Are there any differences in teachers? experiences and strategies between the two selected schools? The study is supported by earlier research that deals with pupils? and teachers? perspective and strategies in different classroom cultures in terms of norm-breaking behaviour of pupils. The study is also supported by three different theoretical perspectives such as power structure, social order/disorder and support strategies.I conducted the study through interviews with sex teachers who work in the same municipality but in two separate schools.

Att ansluta en digital signalprocessor kräver ett omfattande arbete. Innehållet i denna rapport sammanfattar teoretiska metoder för att integrera den digitala signalprocessorn ADAU1701 i talförstärkaren MMT-4, utvecklad av företaget Xena Medical. Arbetet har till största delen bestått i att finna en lämplig DSP och studera dess datamanual för att anpassa den till talförstärkaren.Mycket av rapporten sammanfattar beräkningar av komponentvärden och anpassning av ADAU1701 för MMT-4:s behov. ADAU1701 beskrivs utifrån det så kallade selfboot-läget där processorn kan arbeta som fristående processor..

The visual complexity in real-time applications, like computer games, is increasing with customer demands on vissual apperance. This trend is supported by even better graphics cards from the hardvare industry. This must be taken into consideration when the architecture of a new graphics engine is to be designed. The engines renderer is responsible of generating a picture of scene data. The renderer must cope with increasingly more complex scenes, and must be able to render them depending on available hardvare capasity.

The aim of the study is to investigate how a teacher uses multimodal resources with an interactive whiteboard while teaching reading and writing. The aim is also to investigate what view the teacher has on using an interactive whiteboard while teaching reading and writing. Video-recorded observations and audio-recorded interviews are the methods used to collect data. The analysis was performed from a multimodal perspective and is also inspired by interaction analysis. The result of the analysis showed that the teacher uses several multimodal sign systems in combination with those found on the interactive whiteboard.
