Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

A trend in modern landscape architecture is to design pedestrian streets so that vehicles and people move in the same area. By doing this, traffic tends to slow down. On the market though, there is a lack of furniture that corresponds to the requirements of these kinds of public places. Therefore, I have designed this furniture, called VOX, which is planned to be used on streets, schoolyards and squares. One objective has been to promote the product to the industry.To achieve this, I have been in contact with people from different professions, which have all influenced my designprocess.

The downsizing of the Swedish armed forces during the late 20th century and early 21 th century has caused several thousand people to choose a different career. This undergraduate thesis investigates the self-observed employability and work-place competence of a number of Swedish armed forces officers who has made the transition to a civil career. The thesis seeks to answer questions about how the transition is comprehended, how military merits and competences are valued in civil work places and which differences in ability to use their competences the respondents experience. The study is made using qualitative interviews, which are analysed using a miexed method inspired by phenomenological method. The findings include that the essence of the respondents emplooyability is a shared work indentity as miltary officers and a common experienced problem in translating their merits.

Globalization has stimulated the free markets and has made possible for Swedish companiesto expand internationally. Some markets have been deemed attractive and companies havechosen to enter them. The decisions concerning internationalization and marketing havedetermined the success of the companies on the new market. Therefore, several elementsbecome important: the motives behind the new market entry, the local marketcharacteristics and the adaptation of the four components of the marketing mix ? product,price, place and promotion.The purpose of this thesis is to study how three Swedish companies adapt their marketingmix to the local conditions in Australia and identifies success factors in order to help othercompanies considering a market entry.

The purpose of the survey was to find out how early childhood teachers work with the curriculum of I Ur och Skur with children between 1-3 years in the forest and how such educators are using the outdoor pedagogy in the forest environment in preschool.In order to answer the study's aim and objectives interviews were performed with six teachers in I Ur och Skur kindergartens.What emerged from this study is that forest excursions are a central part of the curriculum and is seen as their educational place. The teachers are working to create a feeling of security among the youngest children of enjoying the woods and also to raise an interest in the children. Natural materials are used during the forest stay and no other toys or materials.The results reveal that educators work to get the smallest children to use and develop their imagination at play and at the same time they are involved with the children in their discovery of the woods. With the smallest children in kindergarten it involves being on the level of children and as a teacher to have the flexibility to change the forest stay environment if needed..

The trend in milk production is similar in Sweden and across the world; the farms are getting fewer but increasingly bigger. The costs for hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially helpful in bigger herds to pinpoint the cows that may be in oestrus. The number of farms with dairy cows that install AMS, Automatic Milking Systems, are increasing, and that also increases the need for sensors to control milk quality and composition when there is no visual control of the milk by a milker before milking starts.For the sensor data to be useful you have to have software designed to analyze and interpret the data to get relevant information that the farmer can use.

It has been proposed that pidgin languages are similar in their marking of tense and aspect. This study wishes to answer three questions: 1) are there similarities in the marking of tense and aspect in pidgins, 2) are there similarities between the source languages and the pidgins they result in, and 3) does the development of tense aspect marking in pidgins follow the general patterns of grammaticalisation observed in other languages. Two quite different approaches are used to analyse the languages. Firstly the concept of grams is used, that is, a representation of a grammatical category in a specific language, e.g. the perfect in Swedish.

Tumour development occurs to a large extent because of dysregulation of the cell cycle. Of particular importance are defects occurring in the G1 phase. The reason why G1 is critical is because of the influence of several signals (external signals as well as cyclins and cdks) on this stage. The G1 phase can be divided into two parts, G1pm and G1ps. Each part has its ?own? restriction point which needs to be passed in order to progress to S phase.

The aim of this essay is to do a queer reading of the early Swedish pentecostal movement, with a special focus on the women within the movement. The main empirical material is Gustaf Emil Söderholms Den svenska pingstväckelsens historia part I and II, published 1927 and 1928, in addition to this a selection of articles from the Swedish pentecostal magazine Evangelii Härold has been used. The theoretical framework consists of Judith Butler's concepts of heterosexual matrix and performativity, as well as interpellation, and of Adrienne Rich's concept of a lesbian continuum. The analysis shows that the evangelist role, as well as the charismatic practices of the movement, made it possible for women to take the position as leader and teacher of congregations, and thereby take up a male subject position. The role as evangelist also made possible a life outside of the heterosexual norm, within the lesbian continuum..

The students are usually eager to develop their mathematical learning. However, the Skolverket can see that this eagerness passes in the early years of school. A study shows that a varied mathematical education creates enthusiasm to learn, which can decrease the negative view of mathematics.The purpose of this study is to see how five pedagogues use laboratory mathematics, their approaches to laboratory mathematics as well as to find out their role in the laboratory education. The result of the study is based on interviews with the pedagogues, who are all teachers for students in year F-3. All of the pedagogues work in a laboratory way, but to different extents.The study shows that the pedagogues aim to make the mathematics as concrete and everyday as possible.

The purpose of this essay is to analyse how and why culture and tradition is created and maintained within a minor student society at a Swedish university by looking at its history. The West Coast Nation student society provided the material which was subsequently analysed and three sociological perspectives were applied in order to give the study a theoretical base. In order to investigate the purpose of the society, durkheimian theories on functionalism were applied. Moreover, Bourdieu?s thoughts on social fields were used as well as Elias? theories on the established and the outsiders.

Ever since the development of the pc and their software, in the early 80´s,architects way of work have changed a lot. Nowadays most of the architectspresent all their works digitally and not with hand drawn material, as they didbefore the pc boom.Digital visualisation technique pushes the limits, when it is about presentingarchitecture projects virtual reality.This report studies how digital visualization technique is used among thearchitects today.Together with architects from ABAKO architect firm in Gothenburg, Sweden,interviews has been made to give answers about what they think about digitalvisualization technique. What are the opportunities, advantages- anddisadvantage with this digital technique?The answers from the architects, together with work that has been done withdigital visualization technique in a project called Project Sofiedal, shows thatthis technique has big opportunities when it comes to create nice looking VRpresentations. The result in this report also shows that this digital technique ismore time demanding compared to hand drawn presentations.The investigation shows that digital visualization technique is a goodcompliment when it is about showing the citizens how future projects willaffect the surrounding.

In cooperation with the Gislaved company Lerocon AB [1], a separation module wasdesigned as a further supplement to the Module System. The aim of theprojectimplementation was that the separation module could be flexible enough to feed themetal pieces, screws, nuts and other items with large variations of size, appearance andmaterial composition. The module should also be cost effective to manufacture.A separation module is a design which is ment to streamline the work in industries withautomation of the lineoperations. The module feeds the details such as screws, nuts, washersand pieces of metal in a continuous flow in which traps separate the details from each other.Traps may vary depending on the purpose and of the details that are fed. Perhaps it isimportant for the user that the detail-orientation is right after the separation module, whichmeans that all the pieces witch aren´t are fed back in return.For companies and industries in lineoperations that can be made more efficient withautomation, are production flow an important watchword.
