medical plants are adapted to different kinds of dormancy to survive in the worst situations. regarding to ecological viewpoint, this kind of adaptation is very important in respect to restriction of genetic draft and decrease of genetic resource of medicinal plants. this leads to plant survival even after prolonged drought. since some of them are endangered species and in the other hand increa...

Abstract. Ultrasonic waves, either bulk waves or guided are commonly used for non-destructive evaluation, example in structural health monitoring. Traditional sensors detecting ultrasonic include metallic strain gauges and piezoelectric ceramics. Recently piezoresistive nanocomposites have emerged as a promising sensor with high sensing range. In this paper, constriction-resistive based made fr...

Abstract Ultrasonic guided waves have the potential for both rapid inspection and in situ monitoring of plate-like structures, and effective signal processing and imaging algorithms are essential to achieve necessary performance. Although guided waves can propagate long distances and still remain sensitive to damage, their dispersive nature and sensitivity to varying environmental and operation...

Integrated Vehicle Health Management (IVHM) combines the use of onboard sensors with artificial intelligence algorithms to automatically identify and monitor structural health issues. A fully integrated approach to IVHM systems demands an understanding of the sensor output relative to the structure, along with sophisticated prognostic systems that automatically draw conclusions about structural...
