The project deals with the evaluation and testing of speaker and microphone elements as well as microphone cavity.The first part of the report comprises a comprehensive theoretical part about drivers, microphone elements, and to some extent microphone cavity.The goal was to , on the behalf of the company Limes Audio AB, develop proposals on microphone element and cavity as well as drivers for a speakerphone application, based on specific factors. The main factors were performance, price and form factor.The aim was to create the best possible conditions for Limes Audio's software developers to implement the company's audio-enhancing software, mainly adaptive echo cancellation.The testing was carried out using Adobe Audition and MatLab. The test methods were developed in conjunction with Limes Audio and are described below.The project will result in suggestions for a speaker, a microphone and a cavity. The cavity were removed from the product because the results indicated that the cavity matter little for the end result.The report concludes with a discussion on how the measurements could have been enhanced to simplify the interpretation of the results and making the testing more efficient..

From an environmental and climate perspective we are becoming more and more aware of what we eat. Consumers want to know how their food is produced and where it is coming from. A term commonly used in this discussion is local produce. At this time, there is no clear definition of the term and a wide range of definitions can be found. However, despite this lack of definition, the term is often being used by producers, traders and consumers..

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

The purpose of this Master?s thesis is to present a survey of how Swedish libraries provide information services for children. In this thesis ?information? means non-fiction material and ?children? do not include preschool children. The method used is knowledge overview and the material (mostly Master theses in LIS published January 2001-June 2006) is related to user studies of children as information seekers.

The aim of this study has been to examine six books about Oscar Wilde?s homosexuality during the years 1906 ? 2003. I have been analyzing their descriptions about his sexual orientation and compared them to each other to see the changes through time. In order to see some clear changes the main focus was to choose time differences between the books. It was clear that the earlier writers had negative opinions and thoughts about his sexual deviation the way they described it.

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

Internal communication is an important factor in organisations today. For many system development teams it?s critical that the communication works well. Without communication, success would be impossible. This study aims to highlight the effect communication has on the members of agile project teams.

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

The purpose of our studyis to investigate how the changed Education Act in Malmoe affects the work of school counselor in elementary school and how it further may affect the work. We were also investigating counselors? views on the politically increasing transparency of student health that comes as a result of the new school organization in Malmoe. To obtain our results, we have chosen to use a qualitative research interview, where we have chosen a semi-structured interview form. We have chosen two theories, Foucault -power and discipline and organizational theory.

This paper deals with prehistoric charred organic material, interpreted as bread, found in graves and in the underlying settlement at Kalvshälla, Järfälla parish in Uppland. The aim was to categorize the organic material morphologically and with the help of Fourier transformed Infrared spectroscopy (FT-IR) to see whether it was bread or not. Material from 13 graves (dated to Late Roman Iron Age until Viking Age) and 3 finds from the settlement have been analysed. Differences were noted both in shape, porosity and structure. Some of the material has been interpreted as cereal based foodstuff instead of bread due to morphological discrepancies.

Background: Every year, patients die while waiting for an organ due to the shortage of donors. When a patient is declared brain dead, the question of possible organ donation arises. In some cases, the patient is registered in the donor registry, but sometimes their stance on donation is unknown. The next of kin then become involved in the decision and are asked both what the patient would have wanted and how they themselves feel about donating their deceased family member?s organs. Aim: The aim of this literature review was to describe relatives' experiences of the decision-making process regarding organ donation after death.

The first four AP-funds have a well-diversified Swedish portfolio, which is managed in similar way as the largest Swedish bank funds. Up until today, there has not been any comparable study that focuses specifically on this part of the AP-funds. Our aim is two-folded; First we will look at how well the AP-funds have managed their Swedish assets compared with Swedish funds of the four largest banks in Sweden during 2002-2006. This will be done by looking at some important key ratios and both absolute and active return. Secondly we will present a descriptive analysis of the management structure within the respective organisations, to be able to draw conclusions regarding the possible deviations in investment return.

The aim of this literature review was to elucidate how suicidal and self-harming patients should be treated and cared for, mainly in the acute phase in somatic care. Searches were conducted in databases with relevant keywords. Qualitative and quantitative articles were included, would not be more than 20 years, be written in Swedish or English, and match the aim of the study. Results showed that nurses and patients felt that the treatment would be respectful, non-judgmental and characterized by active listening and clear communication. Poor care was described as disrespect and lack of understanding.

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.
