Nomination and voting for this election is governed by conference standing order 74. With the exception of those standing for the ‘seventh seat’, candidates do not have to be a representative of a local medical committee at conference. Nominations may be made only by representatives of a local medical committee at conference. A representative may make ONLY ONE nomination. Elections, i...
Standing-wave excitation of fluorescence is highly desirable in optical microscopy because it improves the axial resolution. We demonstrate here that multiplanar excitation of fluorescence by a standing wave can be produced in a single-spot laser scanning microscope by placing a plane reflector close to the specimen. We report here a variation in the intensity of fluorescence of successive plan...
This paper presents a method to seamlessly extend the coverage of energy supply field for wireless sensor networks in order to free sensors from wires and batteries, where the multi-point scheme is employed to overcome path-loss attenuation, while the carrier shift diversity is introduced to mitigate the effect of interference between multiple wave sources. As we focus on the energy transmissio...
A distribution of the meter-wave luminous objects, which are bright at frequency 74 MHz (a wavelength of 4 m) but not detectable at 1.4 GHz (21 cm) in the VLA surveys, shows a notable concentration in a scale of a few degrees toward Monoceros [(l, b)=(225, 4)]. We argue that it is a part of giant radio relics associated with a nearby cluster of galaxies with cz ∼ 2400 km s centered on the spira...
Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...
background: standing workstation can be a strategic approach for many electronics manufacturers to achieve work optimization. however, the well-being of the workers has become a great issue for both workers and employers. the main objective of this research was to study the effects of standing working posture on the workers and their impact to workers’ health and productivity and then to re-des...
A PLL Design Based on a Standing Wave Resonant Oscillator. (August 2010) Vinay Karkala, B. Tech., Indian Institute of Technology Madras, India Chair of Advisory Committee: Dr. Sunil P. Khatri In this thesis, we present a new continuously variable high frequency standing wave oscillator and demonstrate its use in generating the phase locked clock signal of a digital IC. The ring based standing w...
Soil behavior during stress wave propagation was studied on a sand and two clays by making one-dimensional wave propagation tests on 5-meter long columns of the soils. Attempts were made to predict this behavior by determining soil properties in dynamic compression tests on small samples and by using these properties in a variety of mathematical models for soil. In all the wave propagation test...
