The comminution process, particularly grinding, is very important in the mineral processing industry. Some characteristics of ore particles, which occur as a product of grinding process, have a significant impact on the effects of further ore processing. At the same time, this process requires a significant amount of energy which significantly affects the overall processing costs. Therefore, in...

We demonstrate some simple but powerful methods that ease the problem of describing and generating circuits that exhibit a degree of regularity, but are not as beautifully regular as the text-book examples. Our motivating example is not a circuit, but a piece of C code that is widely used in graphics applications. It is a sequence of compare-andswap operations that computes the median of 25 inp...

Amid the blizzard of design-automation technologies, the analytical MOSFET models (and their associated model parameter sets) receive scant attention from the design community. However, these models and parameter sets are fundamental to the design process, since they represent the critical "communication link" between a design group and its wafer foundry. In particular, analog integrated circui...

Filters of some sort are essential to the operation of most electronic circuits. It is therefore in the interest of anyone involved in electronic circuit design to have the ability to develop filter circuits capable of meeting a given set of specifications. delay time steady state error, operating frequency, and wavelength, damping frequency, and wavelength the major interesting design paramete...

An integrated circuit design facility has been established at APL to help tap the vast potential of very large scale integrated circuits for space applications. A custom N-channel metal-oxide semiconductor chip containing 7000 transistors has been successfully fabricated by a silicon foundry using the design database produced by the APL facility. This project is a tangible step toward creating ...

the crossing number of a graph  is the minimum number of edge crossings over all possible drawings of  in a plane. the crossing number is an important measure of the non-planarity of a graph, with applications in discrete and computational geometry and vlsi circuit design. in this paper we introduce vertex centered crossing number and study the same for maximal planar graph.

Simulation of grinding circuits has being performed from 30 years ago and is also to be more complete and powerful approach with improvement of mathematical models which simulate various processing units/machines. The modeling and simulation of various mineral processing circuits are presently performed. In order to simulate the present grinding circuits of Esfordi Phosphate processing plant, a...

Until recently, integrated circuit design was based on the following contract between design andmanufacturing: designs are to follow a set of manufacturing-driven constraints (commonly known as ‘design rules’), and manufacturing is to meet the performance and yield targets in producing the specified design. This arrangement worked for many years until the designs of sub-100nmnodes came along, w...
