The object for this study is a company developing and manufacturing vehicles for heavy transportation. The company distributes their products on a global market. Therefore the company is required to have efficient internal production development processes in order to successfully beat the competition. The purpose of this master thesis is to study how this particular company intends to implement their standardized theoretical product development process within their organization and how well it is done. We intend to identify and specify if the process has any unexploited capacity.

During the last 15 years the Swedish media market has developed a great deal, thanks to the rise of new media. Literature, articles and investigations have contributed to producing the chapter of background of this essay. How the local newspaper and its organization has changed over time is being accounted in this essay. From the newspaper being the only product on the market to now having a spread out product portfolio. By doing the qualitative interview with research representatives of six local newspapers the aimis to answer the following questions: Who were your competitors 15 years ago? Who are your competitiors today? In what way has the increased competition changed your way of working at the division of advertisement and how do you consider the the increase of mediachannels having affected the customer? How do you see the future? The main results show that all six representatives agree on the fact that the competition has increased during the last 15 years.

This study attempts to examine the existence and development of price differences in the car sector in Europe. The time period is between 1995, the year of the Swedish entrance in the European Union, and 2003. The study is based on data supplied by the European commission, on a bi-annual basis. Both price differences in general in the EU, and price differences between Sweden and other countries in the EU are examined. The theoretical law of one price is related to the economic integration of the EU and the car sector.

This master thesis has been done in cooperation with Sweco Viak AB in Sundsvall. The aimwith the project is to investigate the purifying effect of percolation filter due to iron andmanganese. The overall goal was to investigate how the parameters surface load,sandfractions, and burden time affect the purifying effect. The expectation is to optimize thedesign and find a demouldning of the filter that gives sufficient purifying with a highersurface load. As an attempt to accelerate the curing of the filter, experiments with a layer ofsand which surface has been covered with manganese ore (MnO2) on top of the filter havebeen done.As test filters 10 L bars were used and the experimental work was performed at thewaterworks in Hassela and Munkbysjön.In Hassela different sandfractions were tested.

The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.

The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise and repeatable method that would be able to be applied to the process of qualification and technical marking of chemical products at the company, OKG AB in Oskarshamn. A complete instruction for the decomposition equipment and the method of analysis was written. A number of parameters were chosen from the general method of the combustion equipment, which then was tested parallel with a simultaneous development of an appropriate ion chromatographic method.

Those companies that have taken a stand in corporate social responsibility and work with these issues often experience difficulties orienting themselves in these areas. There is a picture of how companies want to be in their CSR commitment on corporate websites and a different reality which is reflected in the media. These different images are not in harmony with each other.The purpose of this study is to revise the CSR work of Sweden?s largest clothing companies.To answer the problem of this study a qualitative method has been used. The choice to explore a few clothing companies resulted in a multi-case study.

The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.

Organizational culture is a widely discussed topic. Today job mobility in society is increasing as well as part-time employment. This study aims at investigate how organizational culture is maintained in an organization where employees work as combiners of different work occupations. The study is a case study of the department of Art at Konstfack (The University College of Arts, Crafts and Design). The organization is unique in the respect to that the majority of the employees have part-time employments within Konstfack combined with their parallel own artistic occupations.

The aim of this Master's thesis is to compare the 6th and the 7th editions of the classification scheme of the Swedish classification system (SAB) to reveal which principles are used concerning the development of this system during the period 1985-1997. Guiding questions are: What kind of changes has been conducted? How do these changes relate to development of other general classification schemes and to theories concerning revision work? The results of the analysis show that possibilities to use synthesis have increased by an extension of use of geographic and chronological subdivisions. The classification scheme has also been easier to use by elimination of parallel subdivisions and regularization of the scheme. To maintain stability revision is performed on selected subclasses.

The aim of the present study was to evaluate the effects of large amounts of straw in the farrowing pen on thermal regulation of the newborn piglet in different weight classes. 20 sows were given 15 kg of straw in the farrowing pen 2 days prior to until 7 days after parturition. A control group of 18 sows had no straw in the pen. 6 litters from each treatment were observed. Measurements of piglet body temperature were made at 0h, 2h, 4h, 8h and 24h after parturition. At ?8h? the body temperature of the piglets in the Straw group were significantly higher (P=0,0149) than the piglets in the Control group.
