Abstarct: This paper presents an algorithm for solving the multi-objective reactive power dispatch problem in a power system. Modal analysis of the system is used for static voltage stability assessment. Loss minimization and maximization of voltage stability margin are taken as the objectives. Generator terminal voltages, reactive power generation of the capacitor banks and tap changing transf...

Grid computing is a network of computer resources where every resources are shared, turning a computer network into a powerful super computers. In which, Grid Scheduling is a non linear multi-objective problem. In this paper, intelligent water drop algorithm is hybridized with Tabu Search algorithm to solve scheduling problem in computational grid. The proposed algorithm named EIWD-TS is a meta...

The aim of this study is to investigate different methods estimating the stress-strength reliability parameter, $\theta =P(Y<X)$, when strength (X) and stress (Y) are independent random variables taken from inverse Weibull distribution (IWD), with same shape parameter scale parameters. Based on Adaptive Type-II Hybrid progressive censored samples, we employ classical Bayesian approaches. In ...

Mosul's city land covers soil, cultivated land, stony, pastoral water, and ploughed agricultural land. We have classified multispectral images captured by the sensor (TM) carried on Landsat satellite. Integrated approach of intelligent water drops (IWDs) algorithm is used to identify natural terrain. In this research, IWDs been suggested find best results for image classification. The purpose u...

The elevation of airport runways is specified in the operations manuals and globally accepted design guidelines. Airport are constantly exposed to various physical weather factors. However, these factors can deteriorate condition runway point where it becomes unusable. Monitoring continuous inspection evenness an important element a sustainable maintenance system. An system detection modelling ...

The development of advanced and intelligent measurement instruments in recent years has increased the intelligence modern energy systems, especially power systems. Besides, with advancement conversion technologies, these systems benefit from multi-carrier resources. Accordingly, this paper presents a model smart city which considers various components, including transportation system (STS), mic...

In an airborne laser bathymetry system, the full-waveform echo signal is usually recorded by discrete sampling. The accuracy of signal recognition and the amount of effective information that can be extracted by conventional methods are limited. To improve the validity and reliability of airborne laser bathymetry data and to extract more information to better understand the water reflection cha...

PURPOSE OF THE STUDY We explore discrepancies in perceptions of values and care preferences between individuals with dementia (IWDs) and their family caregivers. DESIGN AND METHODS We interviewed 266 dyads consisting of an individual with mild to moderate dementia and his or her family caregiver to determine IWDs' beliefs for 5 values related to care (autonomy, burden, control, family, and sa...
