The study of normal impedance of perforated plate acoustic liners including the effect of bias flow was studied. Two impedance models were developed by modeling the internal flows of perforate orifices as infinite tubes with the inclusion of end corrections to handle fi... Lees meer.

Reference values on percent body fat are essential in fitness programmes in identifying variations of body fat from normal and in clinical assessment of overweight and obesity. Accurate evaluation of the presence of excessive body fat is an important step to initiate pr... Lees meer.

The book is divided in 4 parts. In the first one the importance of the analysis of the cardiac dynamics using the ambulatory monitoring technique is presented. The second part contains the description of foundations of impedance cardiography ICG the models used to d... Lees meer.

An antenna with a self-complementary structure has a constant input impedance independent of the source frequency and of the shape of the structure. An antenna with a self-complementary structure has a constant input impedance independent of the source frequency an... Lees meer.

The intention set for this book is to formulate a few topologies with enhanced voltage boost while drawing continuous input current. To further reduce the device switching stress and improve the output waveform quality a series of impedance-source NPC inverters based... Lees meer.
