Abstract Considering similar air traffic control techniques for the present based on close historical dates is a good approach due to unpredictability of weather and traffic, as well increase controller efficiency. A K-prototype clustering technique grey correlation analysis are proposed discover days address problem identification. Firstly, datasets used create set features broken down into nu...
Background: Driving fatigue affects the reaction ability of a driver. The aim of this research is to analyze the relationship between driving fatigue, physiological signals and driver's reaction time. Methods: Twenty subjects were tested during driving. Data pertaining to reaction time and physiological signals including electroencephalograph (EEG) were collected from twenty simulation experime...
INTRODUCTION The role of structural brain changes and their correlations with neuropsychiatric symptoms and disability in Alzheimer's disease are still poorly understood. OBJECTIVE To establish whether structural changes in grey matter volume in patients with mild Alzheimer's disease are associated with neuropsychiatric symptoms and disability METHODS Nineteen Alzheimer's disease patients (...
the problems of shortages and quality deterioration of water, have led to an increased interest in the reuse of treated grey water in many parts of the world. this study examined the suitability of locally available materials (beach sand, oyster shells, and charcoal) to treat grey water samples collected weekly from three halls of residence (unity hall, africa hall, and independence hall) on kw...
Based on the theory of grey correlation, hierarchical teaching quality evaluation and knowledge system structure curriculum are established. Using optimal clustering method, assessment construction at level were obtained, correlation method was used to study course level. Through discipline system, achieved. The found that between grading establishment using higher than 0.900, better evaluated,...
In this paper, we propose an original approach to colour correlation-based stereo matching with mono-dimensional windows. The result of the algorithm is a quasi-dense disparity map associated with its confidence map. For each pixel, correlation indices are computed for several widths of windows and several positions of the current pixel. Three criteria, extracted from each correlation curve, ar...
Frontotemporal dementia is a heterogeneous neurodegenerative disorder with around a third of cases having autosomal dominant inheritance. There is wide variability in phenotype even within affected families, raising questions about the determinants of the progression of disease and age at onset. It has been recently demonstrated that cognitive reserve, as measured by years of formal schooling, ...
assessing financial performance is one of the most important in functional domains, because financial information is considered for the basis of making decisions. organizations use various indexes for assessing performance in quantitative techniques. although these sorts of assessments provide useful information, but the comprehensive concept will never be concluded because of considering all t...
This study was conducted to determine the effects of some environmental parameters (sea surface temperature SST, sea level SL and Volga river water volume VRWV) on biomass of golden grey mullet Chelon aurata in Iranian coastlines of the Caspian Sea. In the study, the catch and population parameters of golden grey mullet during the years 1991-2017 used as input data. In these years, the catch of...
Acquiring optimal dimensions of concrete dams by reducing the cross section will reduce the volume of concrete used and consequently reduce construction costs. Due to multiplicity of constraints which leads to complexity of the decision space, meta-heuristic optimization algorithms have been increasingly used in optimal design of gravity dams. In this study, performance of Grey Wolf Optimizer w...
