The characteristics of VHF radiowave scintillations at 244 MHz (FLEETSAT) during a complete solar cycle (1983±93) at a low-latitude station, Waltair (17.7°N, 83.3°E), are presented. The occurrence of night-time scintillations shows equinoctial maxima and summer minima in all the epochs of solar activity, and follows the solar activity. The daytime scintillation occurrence is negatively correlat...

We present a case of a 45-year-old patient who reported bleeding hemorrhoids. He had grade II hemorrhoids and was found to have a circumferential leukoplakic lesion at the anal verge. The patient had no symptoms of leukoplakia. The hemorrhoids were ablated with an Ellman radiowave device. Histological findings of the incised lesion from the verge showed hyperkeratosis and acanthosis extending c...

Appropriate channel models are needed in order to determine the performance of new emerging space time processing techniques. This paper investigates several properties of the mobile space-time channel, which can be modeled by stochastic parameters of the time-variant azimuth-delay-power-spectrum (ADPS). The raw characteristics of the ADPS are determined from ray tracing methods using the Radio...

This paper outlines the methods of creating detailed coverage maps of 802.11b networks, with an emphasis on minimizing the expenses and time involved. The goal of this work is to develop and present a streamlined, reproducible approach to wireless visualization as well as techniques for predicting coverage area before conducting network installations. After evaluating these coverage maps, a rep...
