This paper investigates control charts for detecting special causes in an ARIMA(0,1,1) process that is being adjusted automatically after each observation using a minimum mean-squared error adjustment policy. It is assumed that the adjustment mechanism is designed to compensate for the inherent variation due to the ARIMA(0,1,1) process, but it is desirable to detect and eliminate special causes...

The Reverse Elimination Method (REM) is a dynamic strategy for managing the tabu list. It is based on logical interdependencies between the solutions encountered during recent iterations of the search. REM provides both a necessary and sufficient condition to prevent cycling. The purpose of this paper is first to incorporate in REM a chronological order rule when cycling is unavoidable, thereby...

The evaluation of vision systems is not possible without parameter control as incorrect parameter adjustment can cause performance losses that are more signiicant than the eeect of the component being tested. In this paper we present a model for the contour extraction process and derive from it a method for automatic parameter control. The method works with arbitrary edge detectors, edge types ...

the best quadratic unbiased estimation (bque) of variance components in the gauss-helmert model is used to combine adjustment of gps/levelling and geoid to determine the individual variance components for each of the three height types. through the research, different reasons for achievement of the negative variance components were discussed and a new modified version of the best quadratic unbi...

Abstract As a clean and effective renewable energy source, PV has been widely used in power systems. The application of VSG technology can effectively improve the system inertia reduction problem caused by grid connection storage units. virtual damping coefficient control have unique advantages being flexible controllable. This paper designs strategy which be flexibly adjusted according to freq...

Studies have shown that high-voltage power transmission lines emit electromagnetic radiation, which has adverse effects on human health. This paper presents the of parameter adjustment electric and magnetic fields an overhead line model at height. A finite element software, COMSOL multiphysics, was used to simulate fields. The generated by 1200-kV 220-kV models were first computed validated com...
