Bluetooth is an emerging technology to build a solution for providing short range, low power, low cost, and ubiquitous wireless environments. In this paper we propose a algorithm for asynchronous data traffic at the Medium Access Control(MAC) layer to meet Bluetooth characteristic and compare with other scheduling algorithms. The algorithm, named Efficient Utilization Polling (EUP), uses a sing...

In this paper, we present simulation results for the performance gain of smart dual antennas at handsets for the forward link in the cdma2000 system. The system was modeled with the SPW of Cadence. Three types of the channel model, two levels of diversity combining, and three diversity combining schemes were investigated. Our simulation results show that the average performance gain (reduction ...

Heart myocardia are critical to the facilitation of heart pumping and blood circulating around body. The biaxial mechanical testing left ventricle (LV) has been extensively utilised build computational model whole with little importance given unique properties right (RV) cardiac septum (SPW). Most those studies focussed on LV then applied obtained characteristics a few modifications side heart....

The article presents the results of a study based on statistical methods for analyzing trends in Russian higher education system over five-year period preceding global crisis provoked by coronavirus pandemic COVID-19. This is one first attempts at large-scale analysis growth rates performance indicators universities recent years. Its results, according to author, make it possible form both genera...

Up to a thirty-fold detectivity enhancement is achieved for an InAs quantum dot infrared photodetector (QDIP) by the excitation of surface plasma waves (SPWs) using a metal photonic crystal (MPC) integrated on top of the detector absorption region. The MPC is a 100 nm-thick gold film perforated with a 3.6 microm period square array of circular holes. A bare QDIP shows a bias-tunable broadband r...

Organic compounds resulting from the decomposition of organic amendments are used in the remediation of trace element (TE) contaminated soils. The mobility, phytoavailability and soil exposure intensity of molybdenum (Mo), chromium (Cr), zinc (Zn), copper (Cu), Cobalt (Co) and Arsenic (As) were evaluated in the phytoremediation of contaminated technosols after the addition of two organic matter...
