this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...

The human-powered self-generator provides the best solution for individuals who need an instantaneous power supply for travel, outdoor, and emergency use, since it is less dependent on weather conditions and occupies less space than other renewable power supplies. However, many commercial portable self-generators that employ hand-cranking are not used as much as expected in daily lives although...

This article is a comparative study of the design spaces of two bio-implantable acoustically excited generator architectures: the bulk-mode piezoelectric plate (plate) and the flexure-mode unimorph piezoelectric diaphragm (diaphragm). The acoustic to electrical power transducers, or generators, are part of an acoustic, or ultrasonic, power transfer system for implantable sensors and medical dev...

Nanocomposite generators convert mechanical energy into electrical and are attractive low-power solutions for self-powered sensors wearables. Homogeneous dispersion, high concentration, orientation of the embedded filler strategies have been assumed to maximize voltage output in nanocomposite generators. This work contrast these assumptions by studying dominance interphase low concentrations (¡...

Exoskeletons comprised of rigid load-bearing structures have been developed for many years, but a new paradigm is to create “exosuits” that apply tensile forces to the body using textiles and utilize the bodys skeletal structure to support compressive forces. Exosuits are intended to augment the musculature by providing small to moderate levels of assistance at appropriate times in the walking ...

The purpose of this research was to examine whether exercisers and nonexercisers are rated similarly on a variety of characteristics by a sample of randomly selected regular exercisers, nonexercisers who intend to exercise, and nonexercisers with no intention to exercise. Previous research by Martin Ginis et al. (2003) has demonstrated an exerciser stereotype that advantages exercisers. It is u...

In this paper, a feasibility study of building a Human Powered Hydrofoil (HPH) vessel is reported. Hydrofoil vessels are a well-known class of high-speed crafts. In addition to high-speed operation, the hydrofoils have a reliable maneuvering capability, good stability and proper operation in waves. Also, a human powered vehicle, nowadays is an advancing idea. Different aspects of the design and...
