Estimating the Performance of Series System’s Production Process
In former Lifetime performance index CL studies, it is usually assume that quality characteristic is the lifetime of an electronic component, engine, camera or in special case lifetime of business. In this paper we suppose that the quality...
Optimal Parameter’s Design in Tuned Liquid Column Damper
n this paper the vibration behaviors of a structure equipped with a tuned liquid column damper (TLCD) are studied. By linearization the equation of motion of the single degree of freedom structure equipped with the TLCD, ...
Pressure Drop and Thermal Performance of CuO/Ethylene Glycol (60%)- Water (40%) Nanofluid in Car Radiator
for prediction of nanofluid pressure drop through the radiator was developed as well. Also,
with increasing the flow rate, the performance index increased and indicated that application of nanofluid in higher
flow rate was affordable....
Fast Voltage and Power Flow Contingency Ranking Using Enhanced Radial Basis Function Neural Network
Deregulation of power system in recent years has changed static security assessment to the major concerns for which fast and accurate evaluation methodology is needed. Contingencies related to voltage violations and power ...
Baysian Estimation of Lifetime Performance Index Based on RSS Sample on RSS Sample
Lifetime performance index (CL) is a flexible and effective tool for evaluating product quality and conforming rate. Ranked set sampling (RSS) scheme is applied for Baysian estimator of CL based on square error loss. We assume that lifetimes...
A QUANTITATIVE VERIFICATION OF EVOLUTIONARY STRUCTURAL OPTIMIZATION FOR NATURAL FREQUENCIES
-based methods to optimum solution have been presented yet. Using a new performance index based on the optimality criteria, this paper presents a quantita-tive verification of the MESO method for some structural elements. In this study, quantitative verification...
Pressure drop and performance characteristics of water based Al2O3 and CuO nanofluids in a triangular duct
concluded that at the same volume fraction of nanoparticles, using Al2O3 nanoparticles is more
beneficial than CuO nanoparticles based on the performance index....
Atmospheric circulation types and winter daily precipitation in Iran
precipitation variability are identified. The relationships between the CTs and the daily precipitation are investigated by computing: (1) the spatial patterns of the performance index (PI) for each CT and (2) the cross tabulations between the frequencies...
On-line Voltage and Power Flow Contingencies Rankings Using Enhanced Radial Basis Function Neural Network and Kernel Principal Compnent Analysis
Timely and accurate assessment of voltage and power flow security is necessary to detect post-contingency problems in order to prevent a large-scale blackout. This article presents an enhanced radial basis function neural ...
