Fire hazard causes lots of economic loss and personal injuries every year. Many ways are proposed to help people escape quickly from dangerous region. As one key step for fire escaping, the fire escaping system detects fire and dynamically provides escaping route to help people escape from fire scene. With the advanced technique, Wireless Sensor Network (WSN), the fire escaping system is develo...

The battle around Brunanburh in 937 has aroused debate particularly about where it was fought. Many locations have been suggested and a serious contender, Bromborough on the Wirral, often too easily dismissed. article examines some of assumptions underlying current theories took place how defeated armies fled, with view to assessing their accuracy terms evidence available sources. It is demonst...

Abstract We search for escaping helium from the hot super-Earth 55 Cnc e by taking high-resolution spectra of 1083 nm line during two transits using Keck/NIRSPEC. detect no absorption down to a 90% upper limit 250 ppm in excess or 0.27 mÅ equivalent width. This corresponds mass-loss rate less than ?10 9 g s ?1 assuming Parker wind model with plausible exosphere temperature 5000–6000 K, although...

bullying is a kind of peers’ altercation which usually occurs in schools. it seems to be a universal phenomenon that can be observed almost in all classrooms. since the expansion of information and communication technologies, there have been social concerns related to negative effects of these networks, especially in adolescents. in this paper which documentary methodology by referring to execu...

Hirayama disease is a rare type of neurological disease commonly manifesting as brachial monomelic amyotrophy in young males of Asian origin, easily understood as juvenile non-progressive cervical amyotrophy. The first case was reported by Hirayama in 1959. The pathogenesis is attributed towards chronic compression of cervical spinal cord during flexion movements of neck in cases where there is...

A random walk is performed over a disordered media composed of N sites random and uniformly distributed inside a d-dimensional hypercube. The walker cannot remain in the same site and hops to one of its n neighboring sites with a transition probability that depends on the distance D between sites according to a cost function E(D). The stochasticity level is parametrized by a formal temperature ...
