People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

Posttraumatiskt stressyndrom (PTSD) kännetecknas av tre huvudsymptom: undvikande, förnekande och hyperspändhet. Även koncentrationssvårigheter, ångest, depression, flashbacks och mardrömmar är vanligt förekommande hos individer med PTSD. Flyktingar i Sverige som har varit med om krig kan uppvisa dessa symptom. Syftet med denna studie är att undersöka terapeuters upplevelser av arbete med patienter med krigsrelaterat PTSD. Intervjuer med åtta terapeuter utfördes.

Hyperthyroidism has become the most commonly diagnosed endocrine disorder in cats. The recommended treatment of choice in the literature is administration of radioactive iodine. This treatment has been available at a few veterinary clinics in Sweden since 1999. Forty-six cats treated with a standard dose (80 MBq) of radioactive iodine (131I) at the Swedish University of Agricultural Sciences in the period 2000-2004 were followed for a median of 13 months (range 3-42 months) by means of a retrospective cohort study design. Tables predicting time of survival after treatment were made. At final follow-up thirty-nine cats (85%) were euthyroid, six cats (13%) remained hyperthyroid and one cat (2%) was hypothyroid.

Syftet med denna studie är att beskriva tillvägagångssätt för att lära personer som sjunger ?falskt? att sjunga mer ?rent?.

Vidare redogörs för det didaktiska perspektiv som studien har som teoretisk utgångspunkt. I metodkapitlet beskrivs den kvalitativa intervjun, vilken är den metod som använts för att genomföra resultatet.

It is a well-known fact that children with ADHD are hyperactive and have a hard time concentrating; therefore it is of interest to examine how teachers deal with this fact. This study expands the understanding of how teachers work with children who has ADHD; the main purpose of this study has been to examine how teachers view students with ADHD and how they work to include these students in the classroom environment.  special pedagogy has been used to analyze the results. The results are based on four interviews in two schools in south of Stockholm with teachers who work in classes that contain children in the third grade, some of the children have been diagnosed with ADHD and some only have strong characteristics for the functional limitation. Findings suggest that teachers? use structure, planning and the modification of students? individual needs to make them included in the classroom education.

The environmental situation is becoming increasingly critical. The energy sector and other industries have a big impact on our climate and the public is raising their voice for companies to admit their responsibility towards the environment and society. Companies engage in corporate social responsibility (CSR) and happily disclose their responsible performance in annual reports. But what messages are they conveying in their CSR-reporting, and what attitudes towards CSR can be found underneath the explicit content? The aim of this study is to discover which discourses exist in CSR-reports from Swedish energy companies, and how these discourses operate.

The purpose has been to investigate leisure-time centers actual work on children with attention deficit disorder. In addition, the study strives to make leisure-time centers way of working, in relation to their assignments, visible. The study has also compared how the leisure-time centers work and what the research says. The survey was conducted with the help of three exploratory interviews with pedagogues and three-piece observations at the leisure-time centers. It was carried out at three different schools in two counties in Sweden.The results of the survey show that the schools are trying to create clear procedures, though the centers succeed with this in varied degrees.

I carried out six interviews in a "resource-school". The pupils were between ten and fifteen years old and they were all boys with a conduct disorder. The purpose of my study was to find out how the pupils experience school and with that starting point I wanted to contribute to the understanding and the importance of the "resource-school" for the pupils' development. My main questions have been to investigate what the pupils recall from their earlier schools, what they consider to be the difference between their current school and earlier schools, why do they attend this school, do they see it like a punishment or a possibility and how do they see their future.One conclusion I got to in my study was the pupils' relation to the staff. Here they found reliable grown ups with whom they created a positive relation to, which gave them better possiblities to develop and grow stronger.

ADHD (Attention Deficit Hyperactivity Disorder) är ett neuropsykiatriskt funktionshinder som ungefär 3-5 procent av alla barn i skolålder är diagnostiserade för. Hälften av de barn som diagnostiseras har kvar symtomen i vuxen ålder. Samtidigt är ADHD en diagnos som varit omdiskuterad under många år, då somliga menar att det inte borde vara en diagnos utan kan vara ett personlighetsdrag och att en diagnostisering kan medföra negativa konsekvenser för en persons självbild. Syftet var att ta reda på hur våra fem respondenter, vuxna personer med en ADHD-diagnos, ser på sitt liv efter att de fått sin diagnos och vad diagnostiseringen har haft för betydelse för dem. Intervjuer med en narrativ ingång användes för att, utifrån den valda frågeställningen sammanfatta och strukturera upp respondenternas berättelser.

Syftet med denna litteraturstudie är att identifiera och beskriva skyddsfaktorernas effekt för psykisk ohälsa. Teorin om skyddsfaktorer till psykisk ohälsa enligt Cullberg, 2003 användes som teoretisk referensram. Metoden var en litteraturstudie där tio granskade artiklar delades in i teman utifrån teorin om skyddsfaktorer för psykisk ohälsa enligt Cullberg, 2003. Dessa teman var social nätverk, arbete/sysselsättning och sammanhang/mening. Resultatet visade att dessa tre skyddsfaktorer utgår från fundamentala behov hos människan, om dessa inte är uppfyllda löper människan större risk att drabbas av psykisk ohälsa.

There was a questionnaire survey that was conducted on patients that visits an eye center in a county in central Sweden. There were a total of 18 people participated in the survey, between 17-92 years old. The questionnaire contained 22 questions and was analyzed with SPSS.

This thesis is a study of social alienation in two novels by Sara Lidman, Regnspiran (1958) and Bära mistel (1960). Taking the Swedish ?people?s home? and the normative view of people that it entailed as its point of departure, it examines the different kinds of alienation present in Lidman?s work. The analysis consists of three main parts. Part one examines geographical alienation in the novels, as well as the process of racialization of bodies that are considered out of place.

Patienter som lider av Münchhausens syndrom hittar på symtom och/eller skadar sig själva i syfte att få uppmärksamhet från sjukvårdspersonal. Det är en svårdiagnostiserad störning som är till skada för individen och hela sjukvårdssystemet. Det har gjorts få undersökningar om Münchhausens syndrom och därför intervjuades fem läkare för att öka kunskapen om Münchhausens syndrom och få svar på vilka möjligheter läkare har att kunna identifiera denna störning, samt vilka åtgärder som då kan bli aktuella. Resultatet visade att läkarna ansåg sig vara för lite insatta om Münchhausens syndrom och att de inte kunde vara helt säkra på att patienten inte hade de besvär som patienten påstod sig lida av. Det fanns heller ingen handlingsplan ifall läkarna misstänkte att en patient inte talade sanning om sitt hälsotillstånd.

Anorexia nervosa is a psychosomatic eating disorder that involves self starvation and fear of gaining weight. Our purpose was to study the methods of treatment available and the function of them.
