چکیده
AImtract--A modified non-dimensional group for modelling the elastic modulus of grinding wheels is proposed and thoroughly discussed. Specific attention is paid to the temperature effect on the variations of the modulus. A new factor called processing parameter is successfully defined to reflect the behaviour of a wheel influenced by the manufacturing processes. The well constructed 3-D diagram shows that the variation of the non-dimensional elastic modulus is well represented by the present prediction and that the proposed method is convenient for both theoretical and engineering applications. In order to offer guidelines for engineers in drawing simple relations from the presented governing parameters, formulation procedures are clearly detailed through some illustrative examples.

Formulas of the propositional modal language with the unary modal operators 0, H,, B,, Zz, I!!,, are considered as schemata of sentences of arithmetic (PA), where q A is interpreted as (a formalization of) “A is PA-provable”, X,,A as “A is PA-equivalent to a &-sentence” and &,A as “A is PA-e...
متن کاملLUT-based FPGA technology mapping under arbitrary net-delay models
The field programmable gate-array (FPGA) has become an important technology in VLSI ASIC designs. Most existing algorithms for performance-driven technology mapping for Lookup-table (LUT) based FPGA designs are based on the unit-delay model. In this paper we study the technology mapping problem under arbitrary net-delay models. We show that if the net delay can be determined or estimated before...
متن کاملError-free boundary evaluation based on a lazy rational arithmetic: a detailed implementation
A new boundary evaluation method is presented. It is based on error-free Boolean operations on polyhedral solids. W e describe, in detail, an intersection algorithm that handles, in a straightforward way, all the possible geometric cases. We also describe a general data structure that allows an unified storage of solid boundaries. The intersection algorithm always runs to completion, producing ...
متن کاملBenchmarking for Distributed Memory Parallel Systems: Gaining Insight from Numbers
The inherent diiculties of benchmarking parallel computers and the motivation behind the development of the GENESIS benchmark suite introduce the paper. Some of the broader issues that must be taken into account with any rigorous benchmarking effort on a distributed memory system are then discussed together with a relevant example. The initial version of the GENESIS benchmarks was used to evalu...
متن کاملAuditory distortion measure for speech coder evaluation - Discrimination information approach,
In this article, we devise a fidelity criterion for quantifying the degree of distortion introduced by a speech coder. An original speech and its coded version are transformed from the time-domain to a perceptual-domain using an auditory (cochlear) model. This perceptual-domain representation provides information pertaining to the probability-of-firings in the neural channels. The introduced co...
