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.

Work Environment problems on construction work sites are very extensive and discussed. The construction industry is one of the most dangerous industries in Sweden. The construction industry occupies about 290 000 employment (2009), and the investment was 250 billion SEK. This report will investigate the issues of the work environment and offer advice on how these can be measured and imporved. The study includes review and analyses of occupational injury statistics, interviews, inspections and audit and review of the literature.

Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.

Lameness localized to the hoof is a common problem in horses. Magnetic resonance imaging (MRI) as a diagnostic tool is becoming more common and is well suited for examination of the distal limb and the hoof capsule. Today there are two different methods of MRI where in one the horse is under general anesthesia and in the other the horse is standing and only sedated. In this study we have compared the visualization of the distal interphalangeal joint using these two methods in two different groups of horses with unknown clinical problems referred to two different equine hospitals. The width of the joint structures including thickness of joint cartilage and joint fluid and also the width of the dorsal pouch of the distal interphalangeal joint were measured.

The thesis has two purposes. First, to give a practical insight into the challenges that Swedish companies might face, and how these challenges are tackled, when implementing strategy in a local area. Second, to develop a general applicable model as a conceptual contribution to the field of international strategy implementation in local areas. This empirical-driven thesis is written in a qualitative and explorative approach, where abduction is adopted in order to find mysteries and contribute to the forming of new theories. The empirical foundation is twenty-two interviews and observations of three large Swedish companies.

The purpose of this study was to create a picture of Södra´s round wood transporters usage, and positive or negative experiences of the KOLA-system. The KOLA-system, owned and managed by SDC, is a program for handling timber orders and displaying their locations on digital maps. The study was conducted as a twenty-three question internet-based survey. Of those asked to complete the survey, 57 percent chose to answer the questions. The results of the study indicated that several of the transporters found the system quite good and used it to a large extent. The system also had many deficiencies however, and there was clear potential for further increasing the usage of the system.

The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.

In scientific investigations on how organizations can learn from their mistakes the perspective is usually that of the social engineer; the object is to prevent human errors through modeling the system in a certain way. The aim of this paper is to explore the learning process from a different standpoint than those usually applied in organizational learning and error theory. By studying the learning process in Swedish health care I seek to discover how theoretical presumptions affect the outcome in terms of what we actually learn. The theoretical framework draws on two major discussions in contemporary political science; the question of structure and agency and the question of whether to focus on formal or informal structures when explaining organizational behavior.The investigation shows that Swedish health care tend to understand human errors as a result of formal organizational structure. Such a view leads to insufficient explanations to why errors occur but is useful in producing preventative measures.

This study analyzes the discursive content of four history textbooks in order to demonstrate how national identities are formed and how they differ from each other. This was done through discourse analysis guided by social constructivism and John M. Hobson?s dichotomy of East and West. The study shows that textbooks mainly construct national identities in three ways; first by making a clear distinction between ?The Self? and ?The Other?, second by preserving a world order based on the notions of the invariant hegemony of the nation-state, and third by utilizing stereotype based dissimilarities in order to accentuate existing differences between nationalities. Implicit ideals and values in the historical discourse play an important part in the construction of identities; however sends a contradictory and ambiguous message.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Sammanfattning: SAAB Communication i Linköping sysslar med konsultverksamhet mot ett flertal nationella och internationella företag inom både den civila och militära sektorn. Fokus ligger på flyget med uppdrag inom telesystem, radiosystem, signaturanpassning, EMC, atmosfärisk påverkan mm. I det sistnämnda ingår även kosmisk strålnings inverkan på elektronik. Den fortsatta miniatyriseringen av elektronik, speciellt minneselektronik leder till ökad känslighet mot den kosmiska partikelstrålningen som ständigt regnar ner på jorden, därför är det extra noga att minnen testas innan de sätts i bruk vid flygburna system. Syftet med detta examensarbete är att konstruera en provplattform som registrerar fel som uppkommer i ett DDR2 SDRAM minne vid påverkan av den ovannämnda strålningen.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
