Speech recognition and speaker detection technique from audio visual fusion information attract much attention. In the visual side information, namely lip reading area, most of recent studies are based on analyzing shape of mouth, whereas few studies are based on analyzing lip motion. However, analysis associated with mouth motion gives essential cues for obtaining utterance mechanics. Thus, as a...
In conclusion, the simulation study using FDTD method suggests that breast cancers with less than 1 cm can be detected by an image reconstruction technique named confocal microwave imaging. Preliminary experiments of an ultrashort-pulse radar confirm that the breast cancer detection is possible by using UWB antennas, such as log-spiral and bow-tie antennas. The additional data processing should be...
Summary form only given. Progress of microwave and millimeter-wave technologies has made possible advanced diagnostics for application to various fields, such as, plasma diagnostics, radio astronomy, alien substance detection, airborne and spaceborne imaging radars called as synthetic aperture radars, living body measurements, and automobile radars for collision avoidance and adaptive cruise control...
Reflectometry is widely used to measure plasma density profiles and density fluctuations in magnetically confined plasmas. When the electromagnetic wave is launched into the plasma, the wave is reflected at the corresponding cutoff layer. Higher frequency wave reflects at the higher density layer. Therefore wide frequency band system is needed to obtain whole density profile. Ultrashort-pulse as a...
This paper reports efficiency improvement of a doubly salient-pole homopolar machine with powder iron core. Powder iron core is composed of the metal magnetization powder with resin. It has advantages of low cost, isotropic magnetic property for three dimensions, a high flexibility of design, and low eddy-current loss at high frequency. This paper shows characteristics and performance comparisons...
Today, vision systems for robots had been widely applied at many important applications. But 3-D vision systems for industrial uses should face to many practical problems. Here, a vision system for bio-production has been introduced. Clone nursery plants are one of the important applications of bio-technology. Most of the production processes of clone nursery plants are highly automated, but the transplanting...
