In this letter, we investigate how a rotary-wing unmanned-aerial vehicle (UAV) acts as wireless base station to provide emergency communication service for post-disaster area with unknown user distribution. The formulated optimization task is find out the optimal path starting and ending at same point serve many possible users under limited battery capacity. We show that problem can be transformed an extended multi-armed bandit (MAB) problem, which propose two efficient planning algorithms....
The weak interaction between rare bases and pure GDY makes detection difficult. B/N doping improves sensitivity, with distinct translocation times responses for each base on modified GDY, aiding cancer diagnosis sensor development.
Abstract The study of denture base resin fabricated by digital technology with surface properties or color stability remains limited. In this study, thermal cycling and staining media (distilled water, artificial saliva, green tea, Coca-Cola) immersion were used to simulate the intraoral environment assess CAD/CAM (milled) 3D-printed materials, conventionally polymerized served as control group. After cycling, all groups showed increased roughness, contact angle (i.e. hydrophilicity)...
Disordered carbons prepared by the pyrolysis of peanut shells with and without a porogen were investigated. The first-cycle lithium insertion capacity porogen-treated carbon was 3504 mAh/g, related to high surface area (2099 m 2 /g) carbon. It concluded from x-ray diffraction studies that extra stored in microporous voids large irreversible for this is believed be associated loss through its reaction groups as well plating subsequent passive film formation. impedance profiles at various...
Recently, unmaned aerial vehicle (UAV) assisted wireless network has been recognized as a promising technology for post-disaster communications, in which multiple UAVs are dynamically deployed the air cellular base stations to provide public connectivities when ground infrastructure collapses. However, due non- uniformity of traffic distribution and large scale area, trajectory planning is considered major challenge UAV- communications many aspects including coverage, energy efficiency...
The environment in underground mine is very complicated, high levels of toxic gases pose a threat to the safety and health workers. But existing single-parameter gas detecting device has disadvantages cost, large volume, poor versatility. This paper designs comprehensive monitoring analysis instrument, which integrates various sensors monitor carbon dioxide, nitrogen oxygen, monoxide, as well particle matter, ambient temperature, humidity. At same time, instrument variety communication...
For the permanent magnet synchronous motor (PMSM)with unbalanced stator resistance, a method for online identification of three-phase resistance is proposed in this paper. According to mathematical model under asymmetrical state motor, estimates quickly and accurately by forgetting factor recursive least (RLS)method. Asymmetry causes an phase current, which generate torque ripple. Therefore, paper also proposes suppress ripple compensating asymmetric stationary coordinate axis. The...
Capacitance-voltage method was used to analyze composition of the Si 1-x Ge x alloy films with a stochiometry gradient Ge, which were epitaxially grown on (100) substrate by chemical vapor deposition. Using capacitance characteristics /Si obtained applying reserve bias Hg electrode probe, contact barrier height for Hg/Si junction and junction, band gap SSi estimated respectively. With , in further obtained. Because analyzed formed through bilateral inter-diffusion into epilayer during...
The frequency dependence of capacitance-voltage (C-V) characteristics Hg/GaN and Hg/InGaN/GaN Schottky contacts are investigated for 1KHz, 10KHz 1MHz at room temperature. An anomalous peak in the C-V curves sample is observed but no occurs. interface states, series resistance minority-carrier injection would be origin this peak. states density calculated through measurement high low frequencies, a four-element circuit model proposed to determine resistance. In addition, energy bind...
In this work, the Si layer is deposited on SiC complex substrate which composed of Si(111) and 3C-SiC film grown it. These 3C–SiC films under different temperatures in a chemical vapor deposition system are analyzed. The crystalline orientation, quality conduction type measured by X-ray diffraction, Raman scattering ,Scanning electron microscope, 1150 °C found optimized temperature for epitaxial growth carbonized layer. Measurement results also show that n-type has same orientation with...
