The developments in an electronic technology can make it possible to fabricate hardware components which contain millions of transistors. The trend of increasing complexity has continued for some time. Recent estimations point out that the number of transistors per chip grows 10 times every six years and the speed of chips increases 10 times every eight years. In this situation, designers have ...

As the number, and diversity, of computer aided design tools used by VLSI circuit designers continues to grow, the need for CAD frameworks increases. While a precise definition of a CAD framework is difficult to give, it is convenient to view a CAD framework as a collection of underlying facilities and services that support activities performed by CAD tool developers, CAD system integrators, an...

This handout is a companion to the ISSAC 2004 tutorial Cylindrical Algebraic Decomposition. It is not intended to stand on its own, rather it is written for someone who has attended the tutorial and taken in the background, motivation, and explanations given there. It is also not intended to thoroughly cite all works pertaining to CAD. It is intended to be a guide to someone who might want to r...

It is essential to know the dynamic parameters of the robot for its precise control and simulation. Philosophy of identification is based on finding the model using its input-output data. The identification equation of the manipulator is derived from Newton-Euler equations, using manipulator kinematic, i.e., geometric parameters and joint values as input and joint torque data as output. In this...

Mammography is a specific type of imaging system used to examine the breast as mentioned by Tang et al (2009) and radiology information available online (2010). Wang and Karayiannis (1998) claim that, one of the difficulties with mammography is that mammograms generally have low contrast. This makes it difficult for the radiologists to interpret the results. CAD is used to aid radiologists in t...

Developing CAD systems for the design and layout of process plant involves an investment of millions of pounds. Today the proven benefit of using such systems is apparent, but without commitment and foresight from software developers such tools may never be seen in the market. One such product, PDMS, was a joint development between CADCentre, Isopipe and Akzo Engineering, started in 1974 and fi...

The aim of this paper is to spread the use of Rapid Prototyping technology (RP) into architecture. Rapid Prototyping is being used since its origin by designers in different fields as product design, automobile industry, medical applications, arts, and it has been proved that it is an essential tool in any design process. The designer has the possibility of building the scale model in very few ...

Geometric algebra is a consistent computational framework in which to define geometric primitives and their relationships. This algebraic approach contains all geometric operators and permits specification of constructions in a coordinate-free manner. Thus, the ideas of geometric algebra are important for developers of CAD systems. This paper gives an introduction to the elements of geometric a...
