The influence of the uniaxial bias stress on the piezoelectric properties of tetragonal BaTiO3 and PbTiO3 monodomain crystals is modeled in the framework of the phenomenological Landau-Ginzburg-Devonshire theory. It is shown that tensile and compressive st ...
Ozonation membrane contact was carried out with a tubular membrane module to study the effects of the flow rates and the temperatures of the liquid phase on ozone transfer and on the enhancement of mass fluxes. Changes in liquid temperature gave both posit ...
In this paper, we study a coherent optical MIMO (COMIEMO) multi-mode fiber link proposed for enhancing the fiber information capacity. We examine the statistical characterization of the equivalent MIMO channel and the improvement in the fiber capacity due ...
In this paper we discuss a number of UHF/RFID tag designs including the hybrid loop (Chen and Hsu, International Symposium on Antennas and Propagation, Korea, Vol. 3, 2005, 1045-1048), dual crossed-dipoles, the dual crossed-dipoles utilizing an inductively ...
Using Landau-Ginzburg-Devonshire theory and tetragonal BaTiO3 as an example, this letter demonstrates that strong electric bias fields applied antiparallel to spontaneous polarization may lead to a large enhancement of piezoelectric properties in monodomai ...
This paper describes our work on a portable non-invasive brain-computer interface (BCI), called Adaptive Brain Interfaces (ABI), that analysis online the users spontaneous electroencephalogram (EEG) signals from which a neural classifier recognizes 3 diffe ...
Severely disabled people are largely excluded from the benefits information and communication technologies have brought to our industries, economies, appliances, and general quality of life. But what if that technology would allow them to communicate their ...
VHDL 1076.1 denotes an effort to enhance the IEEE VHDL 1076 standard with analog and mixed-signal capabilities. In November 1995, the development of the extensions was nearing completion. An IEEE ballot to adopt the extensions as a new IEEE standard should ...
Microchannel reactors promise to display unusually fast response behavior to sharp changes of feed compn. in heterogeneous catalytic systems. In an attempt to use this feature for the elucidation of the transient kinetics and possibly for performance enhan ...
The transient behavior of the dehydration of isopropanol has been studied in a microreactor. The av. productivity under periodic operation is found to be considerably higher compared to steady state even for conversions reaching 80%. The optimal cycle peri ...
