The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

The purpose of this thesis is to investigate reading habits among parents of preschool children who do not use the public library. Another aim has been to investigate why these parents don?t use the library and if there is anything the library can do to change this. Little research had earlier been done on this subject. The theoretical framework consists of two different models.

There are many barriers and obstacles that need to be removed to make the urban environment more accessible for people with disabilities. There are currently no adequate tools for urban planners to assess and address these obstacles. Geographical Information Systems (GIS) provide powerful methods for the visualization and analysis of spatial data, including the kind of data important in studies of accessibility. This study suggests a method urban planners can use to identify accessibility obstacles and to propose future actions to fix them.A literature review was conducted to find out what has been done and what is new regarding the accessibility issues. Different methods were evaluated which in turn led to the construction of a multi-step analytical strategy.

There are several Project Management Softwares onthe market today. These tools are powerful andextensive to the degree they become too timeconsumingand complex and therefore often defeatits original purpose. This is the case especiallywhen the project manager is inexperienced and/orthe scope of the project is moderate.The purpose of this thesis arose from this context,there seems to be a gap between a home-made MSExcel spread sheet and the advanced softwaresavailable. The thesis and the product has beendeveloped in alliance with Faveo ProjectManagement with the shared goal to create a toolwhich is easy to use but still covers the essentialareas of project management theory. The tool willbe used internally by Faveo-employees as well asexternally together with Faveo?s clients in aneducational purpose.

Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

This study aims to investigate and describe the direction of the ideological development of the Swedish gymnastics association Gymniska Förbundet. Between 1928 and 1932, this organization transformed from a purely gymnastic and cultural association into an influential platform for the production of Swedish nationalist ideology. Based on theories of National Socialism?s formation within modern society, the analysis focus on the conditions regulating Gymniska Förbundets relation to modernity. Thus the study examines the association?s ideas in relationship to the concept of modernity.

Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.

Web 2.0 represents the next generation of creating interactive applications on the Web. The purpose of this thesis was to develop a service tailored to Web 2.0 technology, where users can post ads for free. The platform is an advertising system specially designed for animals. Surveys and interviews have been done; the result is that today?s advertising services on the Internet are not interactive and user-friendly.The users have the possibility to adapt different part of the system to their needs, such as choice of themes.

This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.

The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.

The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

Sweden needs a policy that stimulates economic growth. Year 1996 the Business Reorganization Act (1996:764) came into force. The goal with this law was to savebusiness, make it profitable and avoid unnecessary bankruptcies. Shortly afterwards itturned out that the law had no positive effect. A very few numbers of companies appliedfor reconstruction and the number of applications for bankruptcies continued to increase.In 2004, in order to stabilize the situation and bring about neutrality between twoproceedings, company reorganization and bankruptcy, the government proposed thereform of priority rules.
