White matter lesions are small areas of dead cells found in parts of the brain that act as connectors are detected using magnetic resonance imaging (MRI) which has increasingly been an active and challenging research area in computational neuroscience. This paper presents new image segmentation models for automated detection of white matter changes of the brain in an elderly population. The mai...

introduction the iran has vast areas of karst landforms due to the relatively high carbonaceous rocks deposited during different geologic eras. karst landforms are noteworthy for investigation from many aspects. the primary importance of these regions is the considerable amount of underground water stored in karst formations. these reserves are favorable, both in quality and quantity, as natura...

The Emergency Medical Treatment and Labor Act (EMTALA) is a federal law established in 1986 to ensure that patients who present an emergency department receive medical care regardless of means. Violations are reported the Centers for Medicare Medicaid Services can result significant financial penalties. Cheng et al1Cheng T.W. Farber A. Forsyth A.M. Levin S.R. Haqqani M. Kalish J.A. al.Vascular ...

We discuss the desynchronization transition in networks of globally coupled identical oscillators with attractive and repulsive interactions. We show that, if attractive and repulsive groups act in antiphase or close to that, a solitary state emerges with a single repulsive oscillator split up from the others fully synchronized. With further increase of the repulsing strength, the synchronized ...

The paper presents an agent-based approach for monitoring and detecting different kinds of attacks in wireless networks. The long-term goal of this research is to develop a self-adaptive system that will perform real-time, monitoring, analysis, detection, and generation of appropriate responses to intrusive activities. This multi-agent architecture, which supports necessary agent interactions, ...

Particle Swarm Optimization (PSO) is a powerful biologybased optimization search strategy. This paper explores the addition of intuition into the PSO algorithm to improve the speed and number of iterations required to find solutions to the problem. This intuition will be modeled using a fuzzy variable called the Hunch Factor. It will act as memory for the system and influence the choices of the...

In this empirical study a concept map is reorganized and clustered in order to provide an intuitive structure for browsing. The concepts are represented as nodes created by the authors of articles but also by readers of these articles. Semantic dependencies are coded through links between the nodes to build a graph. We report an experiment in which such a concept graph is clustered through fuzz...

In recent years, there has been a tremendous increase in environmental awareness, due to concerns about sustainability. Designing an efficient supply chain network that fulfills the expectation of both business owners and customers and, at same time, pays attention protection is becoming trend commercial world. This study proposes theoretical model incorporating vehicle routing problems (VRPs) ...
