This paper presents parameter identification technique to quantify the faults in motor condition monitoring. Genetic Algorithm (GA) has been used as a key technique to estimate the motor parameters. The zero-sequence voltage equation for the stator has been used as a model to estimate motor stator parameters – the stator resistance and the stator leakage inductance. The comparison of the parame...

Abstract: This paper introduces a new approach to H2 robust filtering design for continuoustime LTI systems subject to linear fractional parameter uncertainty representation. The novelty consists on the determination of a performance certificate, in terms of the gap between lower and upper bounds of a minimax programming problem which defines the optimal robust equilibrium cost. The calculation...

The conventional channel resolvability problem refers to the determination of the minimum rate needed for an input process to approximate the output distribution of a channel in either the total variation distance or the relative entropy. In contrast to previous works, in this paper, we use the (normalized or unnormalized) Rényi divergence (with the Rényi parameter in [0,2]) to measure the leve...

Griffin, William Paul Ph.D., Purdue University, August 2013. Variation-derived Chip Security and Accelerated Simulation of Variations.. Major Professor: Kaushik Roy. In modern ICs, variations can be quite troublesome. Ensuring quality and yield requires careful and resource-intensive simulation under the effects of parameter variations. Threshold voltage approximation of parameter variations ca...

extended abstract abstract pressure management is an effective method for water demand management. for evaluation of the effects of pressure changes on leakage level of water networks, the favad equation is usually used. however, in this equation, exponent of pressure parameter (n) needs to be determined. for estimation of n, either some information about the leak opening is necessary or networ...

introduction: there are several methods for evaluating microleakage in dentistry, for example dye or bacterial leakage, electro-chemical methods, radioisotope labeling and fluid filtration. the purpose of this study was to assemble the fluid filtration system for quantitative evaluation of microleakage in dental materials. materials and methods: the roots were connected to a tube filled with an...

Buried pipe leakage can lead to poor heat transfer performance and even system failure. Leakage analysis of buried tube greatly affects the operation condition diagnosis for exchange in tube. In this study, simulation software was applied analyzing process efficiency pipes under different conditions. Moreover, changes outlet temperature, water pressure flow rate were simulated at positions dive...

Leakage-resilient constructions have attracted significant attention over the last couple of years. In practice, pseudorandom functions are among the most important such primitives, because they are stateless and do not require a secure initialization as, e.g. stream ciphers. However, their deployment in actual applications is still limited by security and efficiency concerns. This paper contri...

In this paper, a mathematical model of leakage sound propagation through a heat exchanger tubes array in boilers is established, which is based on the Twersky’s sound scattering theory, transmission grating diffraction theory, Fabry-Perot’s interference principle, and algebraic iteration method. The tubes array is made up of large number periodically arranged tubes immersed in air. Its acoustic...
