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..

The vegetable production in Sweden is concentrated to the very southern parts of the country. This is also were the major wholesalers are located. In recent years, there has been an extreme focus on price on the food market. As there are only a few big wholesalers and also very few food retail chains, these have a great impact on the producers. The pressure from prominent vegetable-producing countries, providing low price products, such as the Netherlands and Spain is strong.

The society has strongly developed and changed the condition of the trades. The retail trade is no exception; it has changed and developed in the same pace as society. The retail trade is a very broad and extensive trade as all people come in contact with frequently. In the past people shopped locally but nowadays people have the entire world as their marketplace because of the development of Internet. Globalisation gives customers wider opportunities, which demands new and different sales concepts.

Background: The basis for a price valuation of a company is dependent on both its assets net worth and earnings calculations. While the assets are an important part of the valuation of a company, it is important that the valuation is reliable and resource usage can be measured and allocated to each time period. Purpose: The purpose of this essay is to illustrate the difficulties when valuating and allocating own produced fixed assets. Accomplishment: We have chosen a case study where the aims are to understand and explain the difficulties with valuating and allocating own produced fixed assets. The research is based on nine personal interviews.

I made this examination essay to investigate the possibilities and problems with machinery import. The rules intend to loaders and agriculture machines are still pretty flexible. It is today rather simple to make a registration or inspect those machines. There are still some practical problems to be aware of. It is very important to have the right contacts abroad, it is not always that you have time or moment to inspect the machines before purchase. In that case you have to trust your contact or partner about condition, equipment or working hours of the machine. Another important thing is payment before delivery: There is a huge risk that you do not get the machines that you paid for. If problems come up, you need to know the laws, your rights and your duties. A Swedish company does not pay any value-added taxes when it buys from another member of the European union. On the other hand must the machine be sold included value-added tax, if the buyer is a Swedish company.

The task for this thesis is to design a tool that is used to cut-out preforms of thermoplastic adhesive and also to make an estimate of costs for the stamping tool. The tool is used in the repair process at the MCM production line. The result of gathered information has affected how the design of the stamping tool has developed. The handling of thermoplastic adhesive in the repair process is one of the factors that influenced the design. The adhesive is sensitive for exposure to moisture. Therefore an automated feeding system of the adhesive is not recommended. The users wished for an automated stamping tool.

FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among  others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.

A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning. In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..

For the last 50 years the amount of available consumer goods has exploded in number, due to improvements in production and technology. The problem is that the overall sales of many categories are stagnant and retailers are unwilling to grant the categories more shelf space. Therefore many categories are crowded with products and hard for consumers to navigate in. The purpose of this paper is to examine the effects of an assortment reduction on several variables relating to assortment perceptions, customer satisfaction and store choice. The study was carried out as an experiment with 127 participants.

ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?.                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

My project is about attitudes towards disabled people, about our fear for those who are different, about acceptance, ideals and normality.My inspiration has been prosthesis, and mostly people that are born without limbs. Through my research I have come across a lot of questions. Such as, why is a prosthesis so important and for whom? Why is it so important to be normal? What is normal and for who? People that are born different se upon themselves as normal, until they realize that others don?t. Many of them want to learn how to deal with life without prosthesis. And therefore they reject these. Sometimes the prosthesis is aids that are highly necessary.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.
