Deep core temperature is the most basic and important information about health conditions. The non-contact infrared thermometer widely used to measure of human body. However, cannot deep temperature. To overcome this limitation, measuring with a microwave radiometer gaining attention. In study, we propose dual-band on-body near-field antenna for application. proposed has compact size 20 mm �...

this paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (espar). the proposed method is capable of providing better capacity compared to the conventional espar. the termination of each antenna element in this structure comprises a pin diode in addition to a varactor. using pin diode besides the varactor provides more degrees of freed...
Reliable prediction of stellar diameters, particularly angular diameters, is a useful and necessary tool for the increasing number of milliarcsecond resolution studies being carried out in the astronomical community. Specifically, the task of calibrating visibility amplitude information from astronomical interferometers often requires the ability to reliably estimate diameters and uncertainties...
We examined movements and behavior of female white-tailed deer (Odocoileus virginianus) relative to the acorn mast-fall from 1986 through 1989 in a mature deciduous forest in Front Royal, Virginia. Ten white-tailed deer with radiotransmitters increased their home range to incorporate acorn-producing areas during mast-fall. Consumption of acorns by deer constituted ca. 50% of foraging time durin...
