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.

The companies of today figures on a hardly competitive market. This makes it necessary for the company to find new way to create competition advantages. Since it is no longer enough to compete with the technical quality of the product the companies are forced to also enhance the functional quality. To accomplish this it becomes necessary for producing companies to be customer oriented. A customer oriented company culture can be reached with the help of internal marketing in which different activities work to inform and teach the employees about the company strategy and also about their own role as part-time marketers.This thesis examines Electrolux, a company which is currently striving to develop a customer oriented company culture.

The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.

Syftet med denna studie är att beskriva tillvägagångssätt för att lära personer som sjunger ?falskt? att sjunga mer ?rent?. I bakgrundskapitlet presenteras olika teorier kring orsaker till tondövhet och falsksång utifrån forskning och litteratur, samt metoder som rekommenderas för det praktiska arbetet med detsamma. 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.

The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.

Income support is often described as the community?s farthest protection, as a last economic way out. From the clients perspective it´s very important to get possibility to an equivalent and correct assessment. Even if it´s an individual assessment the individual social worker´s assessment should not be different than other social worker´s, this from two aspects ? quality and the rule of law.

This thesis is an evaluative study of the political reform, Friskolereformen, which enabled independent schools to receive state funding. The study evaluates to what extent the incentives, which preceded the reform, have been fulfilled. The evaluation is defined to include upper secondary schools in the municipality of Halmstad during the years of 2005?2010. The reform was enacted on the basis that it would result in a higher standard of quality, efficiency and freedom of choice.

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.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

Large areas have been ditched in Sweden during the past 100 years to improve the forest production. Ditching and also maintenance of old ditches are operations having mainly negative effects on water quality, flora and fauna and changing characteristics of soil. The purpose of this study was to suggest a method for inventory of the need for ditching maintenance in old forest ditches that takes biodiversity, water protection and forest production into consideration. Inventory methods from five Swedish and Finnish forest companies, agencies and organisations were compared. Their employees were interviewed about their handling with ditches, forest production and nature conservation.

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

The Swedish Red Polled breed is threatened by extinction and there are only around 1100 animals left. The breed was popular in the early twentieth century, but since then the numbers have steadily decreased. The overall objective of this study was to find out whether there may be economic incentives for preserving the breed. The milk quality properties are of major importance in the production of dairy products. Therefore we would like to establish if the Swedish Red Polled breed carries favourable alleles at loci of relevance for milk quality, to potentially make the breed more interesting for milk production.

In Sweden, 2011, ley was grown almost as much as cereals, which means that in terms of area, ley is an important crop. A lay can consist of either grass or grass combined with legumes e.g. clover. Forage grasses can be affected by many differ- ent diseases, some during the winter and some during the growing season. The diseases which do damage during the winter are called snow mold and can make large areas perish.
