In recent years, aging problem has been arising to be among the most serious social issues world wide, especially in some European and Asian countries, involving Japan. It is reported in Japan that the population of over 65 years old would reach 30,000,000 in 2012 and grow over 30% of total population in 2025[1]. Electric wheelchairs, personal mobiles, scooters are currently commercially availa...

Abstract We consider a moving target and an active pursing agent, modeled as intelligent Brownian particle capable of sensing the instantaneous location adjusting its direction motion accordingly. An analytical simulation study in two spatial dimensions reveals that pursuit performance depends on interplay between self-propulsion, reorientation, limited maneuverability, random noise. Noise is f...

Information warfare places higher requirements on the remoteness, precision and mobility of artillery weapon systems. As an indispensable important category artillery, mortar plays role. component mortar, base plate bears tremendous impact load. Its design level has influence shooting stability, accuracy maneuverability mortar. Composite helps improve but it will also make force movement rule l...

This paper aims to focus on the path planning problem of AUV in marine environment. As well as considering length and safe obstacle avoidance, ocean currents should not be ignored main factor affecting navigation energy consumption AUV. At same time, satisfy mobility constraint AUV; otherwise, is inaccessible For above problems, this presents a algorithm based an improved particle swarm (EPA-PS...
