Die selbstständige und eigenhändige Anfertigung versichere ich an Eides statt. To my father who introduced me to computers and maths and to my mother who failed to prevent him.

Synchronization is used in dual redundant fault-tolerant system to make two computers work jointly. It determines the work mode and controls the operations of the system. The paper presents a dual redundant fault-tolerant system and proposes its process of synchronization based on task. The synchronization treats task as the minimal operation unit. And it is implemented with the assist of dual-...

The paper describes a peer-to-peer distributed-computing platform based on mobile agents. The platform, called yaca, has been built on top of Aglets, a mobile-agent platform written in Java. Next to the client agents, which seek computational resources in a cluster, yaca consists of four agents, who manage the computers within a cluster. (1) The Directory Agent keeps track of the computers belo...

We describe a system that allows humans and computers to interact without using their hands. Our technology uses human facial traits replace traditional mice in novel way. It employs image processing techniques such as face detection eye extraction. captures an input standard webcam. Controlling the mouse cursor is accomplished by moving up, down, left, right, events are controlled blinks, whil...

Fifteen participants completed a study comparing video game controllers for point-select tasks. We used a Fitts’ law task, as per ISO 9241-9, using the Nintendo Wii Remote for infrared pointing, the Nintendo Classic Controller for analogue stick pointing, and a standard mouse as a baseline condition. The mouse had the highest throughput at 3.78 bps. Both game controllers performed poorly by com...

A few years ago I was writing in this column about differences between languages. Dutch and Chinese are comparatively easy to learn. None the less, the various computer languages are another game altogether. Recently a French colleague in pathology, who is also interested in the use of words and in the modern techniques of the assembly of data bases and word processing was kind enough to let me...

This paper describes the steering controller of the CajunBot II, an autonomous vehicle designed for the DARPA Urban Challenge. The autonomous vehicle is a modified Jeep Wrangler Rubicon equipped with INS/GPS for localization, three sets of sensors and three single board computers. The control objective is to make the lateral error at a certain point ahead of the vehicle zero. The distance of th...

Within the field of Human-Computer Interaction, the study of the interaction between people and computers has revealed many phenomena. For example, highly interactive devices, such as the Apple Macintosh, are often easier to learn and use than keyboard-based devices such as Unix. Similarly, consistent interfaces are easier to learn and use than inconsistent ones. This paper describes an integra...

-Interaction of human beings with computers can be done without any physical interface and this can be done using gestures. The paper addresses a solution to access the music player in the computer via the webcam. This paper mainly deals with detecting and identifying the hand, the skin and the gesture to perform some specific tasks in the music player.
