The solar radiation energy is one of the clean, essential and renewable resources for future. Iran, having 300 annual sunny days, has such intrinsic potential and thermosyphon solar-electrical water heaters (TSEWH) are the simplest solar-thermal convertors. Despite their unique merits, they can not supply hot water for domestic applications during cold period, so, an auxiliary backup system suc...

High pulsed electrical field as pre-processing step for fruits and vegetables in the vacuum freeze drying could increase drying rate efficiency and preserve nutritional ingredients in maximum. Moreover, high pulsed electrical field pretreatment has been successfully used to solve practical problems in the vacuum freeze drying, such as energy consumption, high production costs and long drying ti...

Piezoelectric materials are used in many engineering application. When modeling piezoelectric materials the standard assumption is that the electromagnetic field which is used to actuate the piezoelectric material is quasi static. In this paper we show that although the assumption of a quasi static electrical field is valid when one is interested in simulating a piezoelectric material, this ass...
