In this paper, distributed positioning and tracking schemes for cluster-based wireless sensor networks (WSNs) are presented. We focus on the cases with overlapping cluster regions, which are particularly useful in applications involving inter-cluster communications, time synchronization, and target tracking. In overlapping clustering, the duplicated correlated data between adjacent clusters may...

introducation: emotion regulation and thought-action fusion (taf) are among the most important components which cause psychological disorders. the present study aimed to predict somatoform disorder regarding the emotion regulation and taf in female students of the savadkuh county. methods:   in this descriptive correlation study, 110 middle school female students in the city of savadkuh in the ...

This paper presents a novel approach to change detection in synthetic aperture radar (SAR) images based on image fusion and fuzzy clustering. The proposed approach use mean-ratio image and log-ratio image to generate a difference image by image fusion technique. In order to enhance the information of changed regions and background information in the difference image is based on the wavelet fusi...

An approach based on contourlet image fusion and reformulated fuzzy clustering for change detection in satellite images is introduced in this paper. In this approach fusion of images is used to produce difference image from log ratio and mean ratio images. An optimal difference image should retain the unchanged areas and show the changed areas. So contourlet image fusion is used to generate the...

Homotypic yeast vacuole fusion occurs in three stages: (i) priming reactions, which are independent of vacuole clustering, (ii) docking, in which vacuoles cluster and accumulate fusion proteins and fusion regulatory lipids at a ring-shaped microdomain surrounding the apposed membranes of each docked vacuole, where fusion will occur, and (iii) bilayer fusion/compartment mixing. These stages requ...

Experiments on the interaction of intense, ultrafast pulses with large van der Waals bonded clusters have shown that these clusters can explode with substantial kinetic energy and that the explosion of deuterium clusters can drive nuclear fusion reactions. Producing explosions in deuterated methane clusters with a 100 fs, 100 TW laser pulse, it is found that deuterium ions are accelerated to su...

Abstract – The goal of our work is to develop a scalable methodology to a variety of applications requiring data fusion support for decision-making, which has direct applicability to a disaster or homeland security situation. In this work we have considered a dynamic disaster environment where an earthquake has struck and thousands of casualties are to be attended to. The fusion center outputs ...
