where xi,yi,zi represent the projective coordinates of a point p in the image space and Xw,Yw,Zw,1 represent the projective coordinates of a point P in world coordinates. The actual pixel location of the projected point p denoted (x,y) is ( xi zi , yi zi ). In (1), Mint and Mext are the projection matrices containing the parameters of the projection for the current camera system. Mint is termed...

in forging design the significant parameters are maximum load or energy which are required for the selection of forging press or hammer. these two parameters are varied by the other paramelers such as the geometry of die cavity, flash dimensions, shape of the work piece, friction, mechanical properties of the metal to be forged, temperature, strain rate, and number of the forging operation. the...

A network is a set of devices (often referred to as nodes) connected by communication links built using different physical media. A node can be a computer, telephone, or any other device capable of sending and receiving messages. The communication medium is the physical path by which message travels from sender to receiver. Examples include fiber-optic cable, copper wire, or air carrying radio ...

Quisani: Hello. It's that time of the year again when we have a discussion, isn't it? Author: Come on in. It is a busy time but I am happy to see you. Q: I am afraid my mood is rather critical today. A: That is all right. Speak your mind. Q: It is about computability and decidability. It seems to me that logicians' computability has little to do with real computability. Some so-called computabl...

This chapter asks “What is meant by computermediated communication research?” Numerous databases were examined concerning business, education, psychology, sociology, and social sciences from 1966 through 2005. A survey of the literature produced close to two thousand scholarly journal articles, and bibliometric techniques were used to establish core areas. Specifically, journals, authors, and c...

Animated images are almost magical in their ability to capture our imagination. By telling a compelling story, astounding with special e ects, or mesmerizing with abstract motion, animation can infuse a sequence of inert images with the illusion of motion and life. Creating this illusion, either by hand or with the assistance of computer software, is not easy. Each individual image, or frame, i...

In this paper, we discuss current trends in computer virus research. We begin with a quick review of the theoretical and practical history of viruses. Next we discuss recent results in the two major areas of current work; defending against malicious viruses; and designing useful viruses for efficient parallel processing. Finally we close by discussing future research topics. Copyright c © 1991,...

Laboratory classes are commonplace and essential in biology departments but can sometimes be cumbersome, unreliable, and a drain on time and resources. As university intakes increase, pressure on budgets and staff time can often lead to reduction in practical class provision. Frequently, the ability to use laboratory equipment, mix solutions, and manipulate test animals are essential learning o...
