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.

Bakgrund: Daglig rökning och låg fysisk aktivitet på fritiden är betydligt högre bland individer med psykisk ohälsa. Syfte: Att undersöka dessa samband i ett köns- och socioekonomiskt perspektiv, samt eventuellt finna bakomliggande orsaker. Metod: Använder data från en tvärsnittsstudie (Folkhälsoenkät, Skåne 2000) med en representativ population (n = 11 304) i åldern 18-65. Huvudvariabler är självrapporterad daglig rökning och låg fysisk aktivitet, samt psykisk ohälsa som bedöms via General Health Questionnaire-12. Analyser gjordes med logistisk regression för att få oddskvoter och kontrollera för möjliga confounders. Resultat: Samband finns mellan psykisk ohälsa och daglig rökning, respektive låg fysisk aktivitet bland båda könen, och bland socioekonomiska grupper. Kvinnor har signifikant lägre oddskvoter gällande båda sambanden. Individer med psykisk ohälsa har fler ofördelaktiga levnadsvanor än de med ej psykisk ohälsa, oavsett socioekonomisk status.

This research paper has examined how three teachers in a Swedish state secondary school adapt their teaching to immigrant pupils aged 13 to16 who have recently arrived in the country. The study is based on observation in the classroom and interviews with the teachers. The study showed that all the teachers adapted their teaching methods in the different subjects by actively working with language development during their lessons. The methods employed included explaining words and definitions, using visual methods of teaching and setting frequent written exercises. In this way the pupils developed their language skills whilst covering the subject coursework.

Introduktion: I NNR 2012, har man höjt rekommenderat intag av vitamin D från 7,5 ?g/dag till 10 ?g/dag för personer från 2 år upp till 74 års ålder. Livsmedelsverkets matvaneundersökning Riksmaten bland vuxna 2010-11 visar att medelintaget av vitamin D i genomsnitt var 7,0 ?g/dag. Patienter med inflammatoriska tarmsjukdomar (IBD) har en högre risk för osteoporos på grund av medicinering med cortison samt brist på vitamin D.Syfte: Att undersöka om personer med IBD uppnår de nya höjda rekommendationerna gällande intag av vitamin D via maten och/eller kosttillägg och kosttillskott.

As companies exert themselves to find new ways of achieving market dominance and stronger brands, the phenomenon co-branding has become increasingly popular. By cooperation between two different firms the combined effects can result in synergies not only on the balance sheet, but even through softer values such as Brand recognition, equity and larger market share. Recently the fashion company H&M launched a collection together with the esteemed fashion designer Karl Lagerfeld. The objective of this paper is to examine the effects the collaboration had on consumer?s attitudes towards the two brands.

This diploma work was conducted in collaboration with the Swedish civil engineeringconstruction company Skanska Construction in Stockholm.

E-commerce is becoming more common in Sweden and many Swedes buy clothing and sporting goods online. Online fashion retailers offer a visually pleasing range of products, which places greater emphasis on the aesthetic design of the online retailer. This paper examines how the perceived credibility of an online fashion retailer is influenced by the aesthetic design through a first impression. This study was conducted through ten interviews where the informants observed, assessed, and then discussed the online fashion retailers that were used in this study. Results show that recognition of an aesthetic design and a perception of usability and professionalism affects the perceived credibility in a positive way.

This study is about an ongoing project in the northern parts of Sweden. Quattro Helix is used as a model for the interaction between four institutional members of the society, in purpose of challenging existing social structures and achieveing community development. The aim is to increase the knowledge about Quattro Helix-model as an approaching method to face the problems in the society through cooperation between Civil society, state, academy and industry. Interviews with eight project members were used as the data-collecting method to capture the perceptions about the project constellations. Information was gathered from two representatives from each of the four actors.

Bristen på manliga lärare i grundskolan har diskuterats i decennier. Hem- och konsumentkunskap (hkk) har beskrivits som kvinnligt kodat och bara var tionde lärare i ämnet är man. I uppsatsen undersöks därför hur manliga hkk-lärare beskriver vardagen i ett kvinnodominerat yrke. Studien bygger på semistrukturerade intervjuer med sju informanter.Merparten av männen har tidigare arbetat i restaurang- eller storkök, och för flera var ämnet ett biämne i lärarutbildningen. Informanterna visar glädje och stolthet i yrket och framhåller eleverna som drivkraft.

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.

This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

Då Host Mobility endast har existerat i två år har de inte hunnit med att skapa en bred kundbas för sina telematikdatorer. Syftet med examensarbetet har varit att utreda och ta fram en systemlösning för ett mindre Fleet Management system vilket sedan skulle implementeras med Host Mobility AB:s telematikdatorer.

Syftet med den här studien var att undersöka om mental trötthet leder till ökad diskriminering av överviktiga. Genom att använda en dual process-modell, inleddes undersökningen med en bedömningsuppgift som deltagarna fick utföra i labbmiljö. Vid ett senare tillfälle fick var och en ombesörja att de genomförde ett implicit associationstest (IAT), följt av en explicit graderingsfråga, där deltagarna uppskattade en eventuell skillnad i normal- kontra överviktigas mentala prestation. Syftet med dessa tester var att ta reda på om diskriminering mot överviktiga existerade inom gruppen i sin helhet på såväl implicit som explicit nivå. Hälften av gruppen hade genomgått en kraftig mental trötthetsbelastning före bedömningsuppgiften, med avsikt att se om bias mot överviktiga ökade vid mental trötthet.

Interviews have been made with the initiative owner of the company LHG Learning Center and with civil servants in the municipality of Lycksele. The conclusions drawn in this study are that the establishment of LHG Learning Centers in Lycksele will include both opportunities and risks for the municipality?s future.

The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.
