Determination and selecting the optimum thickness of insulation for buildings in hot countries by accounting for solar radiation
(
Elsevier
, 2004 , Article)
Determination and selecting the optimum thickness of insulation is the prime interest of many engineering applications. One of those applications is insulating buildings with an appropriate insulation. Calculations have ...
Harmonic modeling of linear and nonlinear loads based on Kalman filtering algorithm
(
Elsevier
, 2004 , Article)
Most harmonic nonlinear load modeling techniques developed in the last two decades, assume that the load connected to the load bus has a constant admittance, inductive or capacitive, which depends on the mode of operation ...
A new digital transformation for harmonics and DC offset removal for the distance fault locator algorithm
(
Elsevier
, 2004 , Article)
This paper presents a new application of Park's transformations to identifying the positive sequence of the fundamental components of the three-phase voltage or current signals needed for fault locator algorithm. The problem ...
Identification of individual types of harmonic loads in an electric power system-bus
(
Elsevier
, 2004 , Article)
Some buses in a power system feed power to loads that are sources of harmonics. This type of bus is called a complex-bus. This paper provides a new application of the constrained least absolute value algorithm (LAV) to ...

Power system frequency estimation based on simulated annealing: A variable frequency model
(
Sharif University of Technology
, 2004 , Article)
This paper presents a new technique for measuring power system frequency, rate of change of frequency and the voltage amplitude and phase angle using the Simulated Annealing (SA) based optimization algorithm. The algorithm ...
Surface layer modification of ion bombarded HDPE
(
Elsevier
, 2004 , Article)
Press-moulded, high density polyethylene (HDPE) samples were subjected to ion bombardment and effects of the modification studied. He+ ions of energy 100 keV or Ar+ ions of energy 130 keV were applied in the range of dose ...
