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.

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.

Under de senare åren har det gjorts stora framsteg inom neurologin vad gäller koppling hjärna ? inlärning. Tidigare ansågs intelligens vara något bestämt och oföränderligt, men nu hävdar neurologerna att människan själv sätter gränsen för sin intelligens. Alla människor har förmågan att förbättra och utveckla sin intelligens. För att lyckas med detta bör främst två väsentliga faktorer beaktas i skolan: dels att alla är unika och har olika sätt att inhämta information, dels att det är avgörande om människan befinner sig i en stimulerande miljö eller inte.

Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain. When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced. Facts about the causes of injection-associated pain have been studied in a literature review.

Stroke is caused by a bleeding or infarct in the brain and is one of the most common diseases in Sweden today. The purpose of the study was to evaluate if Ronnie Gardiner?s Rhythm Therapy (RGR-therapy) has any effect, regarding motor control and the subjective experienced health related quality of life, on people who have been affected by stroke. The examination group consisted of eight people. The intervention consisted of RGR-therapy once a week during a period of nine weeks.

Background:Alzheimer´s disease is a so-called degenerative dementia in which brain cells gradually degenerate and die. The disease causes memory disorders and the trait of character disappears. Alzheimer´s disease also affects the related parties that may take a great responsibility. Related caregivers are entitled to support from healthcare. Aim:The aim of the study was to describe the experiences of being related when caring for a person suffering from Alzheimer´s disease.

Today's climate and environmental issues have now been up for discussion for quite long. Various environmental measures have been taken, but it is not always certain that those measures actually are for the better because of the complexity of our environment. Therefore, studies of whole life cycles are very important even if they are time and resource intensive.Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are therefore of great importance.

This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.

The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised reinforcement learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.

Detta examensarbete handlar om hjärnans utveckling, inlärningen och våra inre inlärningsstilar. Det tar också upp kort om hur man kan utnyttja inlärningsstilar i skolan. Syftet har varit att ta reda på hur vi utvecklas och hur de utvecklingsstrukturer ser ut som vi föds med och utvecklar efterhand. De frågeställningar jag haft under skrivandets gång har varit: Vilka är "de sju olika intelligenserna"? Hur utvecklas hjärnan? Var och när börjar vi lära, och vad är det som ligger till grund för vår inlärning? Hur kan man bearbeta olika inlärningsstilar i skolans högre stadier? Den metod jag använt är en litteraturstudie med litteratur som behandlar inlärningen, hjärnans utveckling, hur vi tänker och lär mm.

ABSTRACTThe aim of the study was to examine the prevalence and the location as well as the registration of gingival recessions among patients between 20-29 years of age, who are treated on the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a recording study, where the first page of the base record paper was examined. We examined 295 base records. The result showed that gingival recessions only were registered on 3 % (n=10). Most of the injuries, 53 % (n=157), had been registered as toothbrush trauma.

This paper is a study about outdoor education in pre- school. The main purpose is to look over if outdoor education in pre- school is a restraint or a resource. The study is based on two questionnaires, one to personnel in pre- school and one to parents who have children in pre- school. The study showed that outdoor education is mostly viewed to be a resource but there can be some problems in how to use it. Time, planning and knowledge were problems that were often mentioned by teachers.

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.
