To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming interface (API) to be used when developing volume-rendering applications. A complete application programming interface has been designed. The interface is designed so that it makes writing application programs containing volume rendering fast and easy. The interface also makes created application programs hardware independent.

This bachelor thesis examines and discusses the question: "How can graphics for newscasts be adapted to follow technological developments in various media and increase its informative quality?" The work was performed on Swedish Television's own graphic department, SVT design in order to examine how news graphics need to be developed to follow the technological changes in media. The production resulted in a news graphics concept divided into three parts. Two of the sections show examples of how graphics can be adapted according to platform and the third section shows examples of news graphics that are produced at SVT Design by me. The bachelor thesis focuses on the development of technology in the media and examines areas such as interactive solutions, news graphics and the traditional television media..

In the media richness of everyday life, the encounter with information graphics ishappening on a daily basis, whether we are aware or not. With the development andeasy access of technologies, new ways to create and display information graphics hasemerged. Among them, the animated information graphics, which in the few pastyears appears to have increased in popularity on video sharing websites such asVimeo and Youtube. In the genre of animated information graphics, there seems to bean inherent diversity regarding the design characteristics. In this study we exploredliterature and research on information graphics and related subjects.

News graphics as a part of journalism is something that?s constantly developing along with the news. That?s what we believed when we started this paper including its study. And we still believe the same, now that we?re done.News graphics itself is fairly common in Swedish newspapers, it can be seen every day in almost any major newspaper and is perfect for describing an event like the pollution of the sea over many years or just simply point out on a map where a city is located.This is one of the reasons to why we wrote this; another reason is that there?s almost nothing else written on the subject in northern Europe.

The visual complexity in real-time applications, like computer games, is increasing with customer demands on vissual apperance. This trend is supported by even better graphics cards from the hardvare industry. This must be taken into consideration when the architecture of a new graphics engine is to be designed. The engines renderer is responsible of generating a picture of scene data. The renderer must cope with increasingly more complex scenes, and must be able to render them depending on available hardvare capasity.

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.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..

Om man vill skapa ett realistiskt hav inom Computer Graphics är det viktigt att man har snygga övergångar till andra material. Ett exempel på detta är stränder och det är precis där fokusen på den här studien har legat. Studien gick ut på att hitta en enklare lösning på att visuellt förbättra stränder inom Computer Graphics. För att göra detta så testade två olika metoder i olika experiment. Den ena tekniken som testades var att simulera partiklar för att få fram en bättre strandlinje och de andra var att skapa en shader för att förbättra den.

Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.

This essay serves to illustrate the main practical differences between the popular medium-level programming language C++ (C Plus Plus), and the newer high-level language C# (C Sharp). It will focus on the aspects that are readily apparent to the application programmer, such as differing syntax, constraints and capabilities.It will also feature a similar comparison between the open source OpenGL graphics library, and the proprietary Direct3D graphics library owned by Microsoft Corporation.It will not go into the differences in ?under the hood? mechanics that the application programmer seldom have to consider after having chosen his programming language or graphics API, such as C# being compiled into an intermediate language and is run on a virtual machine where C++ is compiled directly to machine code, or the differing principles of rendering in OpenGL and Direct3D.This is by no means comprehensive, many things have been left out or overlooked..

In this report hardware based alternatives to password authentication in a Windows domain are evaluated for the needs of a certain company. In order to investigate the demands on such alternatives interviews with people concerned have been carried out. The demands which resulted from the interviews have been used to select types of hardware tokens for evaluation. Two products which offer authentication with smart cards and USB tokens have been selected and closer evaluated. These are RSA Passage which offers both hardware options and Rainbow iKey which uses USB tokens.

In this report I have made various comparisons between different client solutions; a standard client solution (PC-server), to use as a comparison and look at various differences in costs against the other client solutions that I have compared, which is Windows Thin PC, Dell Wyse, Red Hat Enterprise Virtualization and FSData terminal server/thin clients. All these solutions require a form of server to work against, which also the standard solution uses, but the main difference is that most of the data and computing power is on the server instead of the client.Window Thin PC, Dell Wyse, Red Hat EV and FSData all use some kind of thin client as hardware. Some of the main differences is that Windows Thin PC can be installed on almost any hardware. Dell Wyse is a special hardware group from Dell, that uses its own proprietary software, and Red Hat EV which is based on linux, is the cheapest option where the only cost is for support. FSData terminal server/thin client use as the name suggest a terminal server and a form of thin client to connect to it, the solution essentially means that your rent the complete hardware from FSData.The comparisons are made with the view of different scenarios based of the number of clients, where costs and licenses, as well as time spent on installation, upgrades, monitoring and managing are some of the main points raised..

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.

The purpose of this thesis was to create a communication interface which insures that all the right hardware is in its right place in the IS-node before Ericsson AB delivers it to their customers. One of the first parts of this work was to make sure it is possible to create such an interface for IS. This thesis then explains how to construct an interface that retrieves information from the IS-node into a C#-application. One important part of this project was to collect information and transform it to an XML output with the purpose of then being used in other applications in the future. The application created within the scope of the thesis exports the information retrieved from the IS-node in an XML-file or a text-file.
