Carrot cubes were firstly blanched by radio frequency (RF) heating and then pre-dried by ultrasound-assisted osmotic dehydration (UOD). Hot air–assisted radio frequency (HA-RF) was applied as a final-stage drying method for pre-dried carrot cubes i

What can be done to promote student–instructor interaction in a large lecture class? One approach is to use a personal response system (or ‘‘clickers”) in which students press a button on a hand-held remote control device corresponding to the

Constructing indoor radio maps plays an important role in many services and applications, such as wireless base station planning. We propose a hybrid approach to constructing indoor radio maps by developing a novel indoor signal propagation model, ca
