This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

The last couple of years the use of mobile devices such as mobile phones and PDAs has increased tremendously. Most of the these devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.

There is an increased pressure for firms to provide the financial market with additional information. Such disclosure is attached with different kinds of costs. In spite of these costs, and in spite of increased mandatory disclosures, firms choose to voluntary disclosure financial information to analysts and others. This indicates that firms also benefit from providing additional information. The subjects of this study is 431 annual reports from firms listed at the Stockholm Stock Exchange for 2002 and 2005 and the objective is to survey factors that can explain variations in firms? voluntary disclosure.

Arbetets didaktiska upplägg utgår från ett barnprogram som underlag i undervisningen i grundskolans tidigare år. Undervisningen ska hålla hög pedagogisk standard och uppfylla de läromål som finns angivna i läroplanen.

Sandvik har idag ingen standard för hur webbapplikationer ser ut på olika plattformar. Därför kan utseendet skilja sig mellan olika plattformar och de använder olika stylesheets för att forma designen. Uppgiften är att skapa en mall som ger samma resultat designmässigt oavsett vilken plattform som används. För att genomföra detta används olika utvecklingsmiljöer på olika plattformar. Skapandet av mallen utgår från intranätet och dess riktlinjer och de standarder som är aktuella idag kontrolleras..

OpenGL is a standard API that is used to manage 3D graphics on desktop computers. Although OpenGL is independent of customized hardware it?s not suitable for all kinds of devices. Therefore both OpenGL ES andWebGL was created. These can be viewed as subsets of OpenGL.

The main purpose with this master's thesis was to develop a survey with the intention to examine what expectations the JM AB:s customer had on a future garden and also to discuss if the lawn has a symbolic meaning in gardens. The lion's share of the thesis is based on a survey, aimed at people in the company's customer database. The intention was to examine what expectations they had on their future garden and if their expectations were met when they later bought a house from the company. The work also consists of interviews and visits to areas with newly built homes. I interpreted the result from my surveys as the lawn on its own being is a strong symbol for a garden and also signals a social status of the owner. To the company the pre made lawn on a role is a way of saving time and easily achieve what the customer request. The company wants to create a concept of a "preset-garden" that meets the company's vision as well as the expectations of the customer.

This thesis is based on a case study of the City of Stockholm. The study aims to explore the effects on the city's large investments caused by the public reform. Furthermore, the question concerns the character of the impact and if it will affect what type of investments that will be prioritized. The theoretical background is based on Brunsson's ideas about political organizations shifting towards corporate nature, and Almqvist's interpretation of New Public Management (NPM). Moreover, models explaining public management reform, and the main components of corporate shifting, are used.

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.

AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.

 Dagens ekonomi är i mycket större utsträckning än tidigare inriktad mot tjänst och kunskapsintensiva organisationer, vilket har lett till en genomgripande strukturell förändring, det immateriella kapitalet är på väg att konkurrera ut de fysiska kapitalen. Därför är det viktigt att synliggöra denna förändring och anpassa redovisningen för att kunna skapa väl fungerade arbetsmetoder för företagen. Målet med redovisning är att redovisningen skall ge en rättvisande bild av företagets finansiella ställning. Vilka tillgångar som skall redovisas i balansräkningen för att ge en så rättvisande bild som möjligt är en svår fråga.Ett företags tillgångar kan vara både materiella och immateriella. Kraven för att få aktivera en utgift som en immateriell tillgång i balansräkningen är hårda.

These days most companies conduct some form of work for the external environment, quality and safety. In connection with this work, some companies have chosen to get management systems certified by any applicable standard for one or more of the fields while other companies have chosen other ways that are not associated with certification.In light of the fact that the individual systems are becoming unmanageable an increasing number of these companies are faced with the decision whether to integrate and coordinate these different systems or not. In order to study the possibilities of a company?s system coordination an assessment of elements particularly interesting for the company was performed. The key elements and focuses in the evaluation were staff access to information, experiences from other companies and environmental work status for some of the organization's companies.

Redovisningen har många olika nyanser, vilket beror på alla de möjliga val som en redovisareställs inför. Copeland (1968) säger att det finns 30 miljoner olika sätt, på vilket ett företagsresultat kan beräknas, inom ramen för de redovisningsstandarder som finns. Med det sagt, kanmanipulering av resultatet koordineras med en standard eller utan en standard. I bakgrundenav studien presenterar vi begreppet income smoothing och i problemdiskussionen utvecklar vibegreppet ett steg längre genom att utveckla ett koncept av tre relaterande begrepp; motivstruktur-resultat. Därefter såg vi det utifrån en praktisk synvinkel och utvecklade treforskningsfrågor: Hur utbrett är income smoothing bland stora svenska företag? Vilka motivoch vilken struktur har svenska börsnoterade företag för att jämna ut sina resultat? Vilkeneffekt får income smoothing på företagets börsvärde? Vidare har vår metod till största delvarit operationell då vi utvecklat konceptet motiv-struktur-resultat och använt finansiellarapporter som informationskälla.

The new Swedish Companies Act allows Swedish companies to issue two instruments that were previously prohibited: mandatory convertibles and participating debentures. The aim of the thesis is to conduct a cross sectional study of Swedish corporate hybrid securities, especially in the light of the new Companies Act. The cross sectional study also includes areas such as credit rating, accounting and tax. The thesis concludes that it is possible, under Swedish law, to issue corporate hybrid securities that qualify for both high equity credit and tax deductible interest payments. The use of certain hybrid provisions are, however, restrained by Swedish company law.
