The transmission line transfer matrix method (TLTMM) is presented for the analysis of multilayer electric structures as frequency selective surfaces (FSS), whereby the reflection, transmission and absorption coefficients, field distribution and power flow may be computed inside and outside of the layers. The TLTMM formulation may be developed for any arbitrary angle of incidence, any polarizati...

During prostate needle insertion, the gland rotates and displaces resulting in needle placement inaccuracy. To compensate for this error, we proposed master-slave needle steering under real-time MRI in a previous study. For MRIcompatibility and accurate motion control, the master (and the slave) robot uses piezo actuators. These actuators however, are non-backdrivable. To cope with this issue, ...

Chickpea (Cicer arietinum L. cv. GPF2) and soybean (Glycine max (L.) Merrill cv. Brag) genotypes were subjected to varying water stress levels of -0.2 to -0.8 MPa to assess their relative sensitivity towards water stress. Soybean seedlings experienced significantly more stress injury (as electrolyte leakage) than chickpea at all stress levels. LD 50 in terms of percent germination, root length,...

Some say that the typical U.S. corporation never was competitive. Tom Peters, co-author of In Search of Excellence, says that All)erican dominance of the world's markets during the three decades following WWII was nothing to brag about. He points out that Americans actually dominated through default. There was no real competition as we know it today, and consequently U.S. companies grew fat, ha...

conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...
