Inhaltsangabe:Abstract: The visualisation of information is a broad area of study not uniquely associated with computing. Its origins can be traced back to the earliest attempts at cartography. It is, however, with the development of computing technology that the discipline has flourished. It is not simply that the technology has allowed for more detailed visual representations to be produced, it is equally the case that the wealth of data available and the understanding of its importance have accelerated the demand for its analysis. The range of modern visualisation is huge, including medical imaging, engineering simulations and geographical and meteorological analysis. Information can come in many forms the two most common to visualisation are numerical data and functional representation. This thesis investigates visualisation methods for both mathematical functions of two variables and three-dimensional data. In particular I examined techniques as contour plots and surface plots. Within the bounds of this project OpenGL turned out to be the most powerful tool regarding visualisation of information. Due to the procedural architecture of OpenGL and an ambition to learn the core architecture of Microsoft Windows®, I decided to exclusively implement this project in Win32®, for which I pay particular attention in this dissertation.

Categorization, the basic cognitive process of arranging objects into categories, is a fundamental process in human and machine intelligence and is central to investigations and research in cognitive science. Until now, categorization has been approached from singular disciplinary perspectives with little overlap or communication between the disciplines involved (Linguistics, Psychology, Philosophy, Neuroscience, Computer Science, Cognitive Anthropology). Henri Cohen and Claire Lefebvre have gathered together a stellar collection of contributors in this unique, ambitious attempt to bring together converging disciplinary and conceptual perspectives on this topic. "Categorization is a key concept across the range of cognitive sciences, including linguistics and philosophy, yet hitherto it has been hard to find accounts that go beyond the concerns of one or two individual disciplines. The Handbook of Categorization in Cognitive Science provides just the sort of interdisciplinary approach that is necessary to synthesize knowledge from the different fields and provide the basis for future innovation." Professor Bernard Comrie, Department of Linguistics, Max Planck Institute for Evolutionary Anthropology, Germany "Anyone concerned with language, semantics, or categorization will want to have this encyclopedic collection." Professor Eleanor Rosch, Dept of Psychology, University of California, Berkeley, USA

It was approximately two decades ago that the support of communication and collaboration became an important research issue. The technical stimulation for this was the spread of personal computers and computer networks, whilst the social driver was the demand for the support of everyday work, frequently including group work and teamwork. This field of research has become known as Computer-Supported Cooperative Work whilst the systems to support group work are called groupware. Over the two decades, research has been extensively conducted. Various Web-based systems have been researched, some of which are aimed at the support of communication and collaboration. Mobile phones have spread rapidly and communication and collaboration support systems have also been researched on this platform. There are many other technologies such as virtual reality, robotics, multimedia, and ubiquitous computing, each of which provides opportunities for the research field. As the research field is not dependent on the type of technology, but is dependent on the needs of human activity and human beings are social animals, the technical demands of supporting social activities do not diminish. Technologies that potentially are useful for this purpose are being investigated whilst new technologies are invented. As a result of the development of IT, the research and development of communication and collaboration systems is increasingly active. The scope of this publication extends from perspectives, design principles, guidelines and social aspects of communication and collaboration support systems to the various application systems and the platform technologies.
