Thin-Film LSCs Based on PMMA Nanohybrid Coatings: Device Optimization and Outdoor Performance by S. M. El-Bashir, O. A. AlHarbi, M. S. AlSalhi

“…The outdoor performance of optimized TLSC was also evaluated under clear sky conditions of Riyadh city, and the hourly values of the optical efficiency, ηopt, were calculated for one year. The best performance was achieved in summer since the short circuit current for PV cell was doubled after being attached to TLSC and the value of ηopt reached 40% which is higher than other values recorded before due to the abundant solar energy potential in the Arabian Peninsula.…”

Layout Optimization of Pajiang River Flood Storage and Detention Area Based on Joint Flood Control and Operation Model by XIN Yue, LIAO Xiaolong, ZHONG Yixuan, QUAN Xujian, YU Baishun

“…Flood storage and detention areas play an irreplaceable role in flood control and disaster mitigation in river basins.However,the significant weakness of safety layout and safety facility construction of flood storage and detention areas in Pajiang River results in difficult decision making and great loss in flood control application,constraining the application effect of flood control.To this end,this paper proposes a layout optimization scheme by combining the flood control capability in each dike and socioeconomic conditions in the studied detention areas.Then,joint flood control and operation model related to Feilaixia Reservoir-Pajiang River flood storage and detention areas is employed to analyze and calculate the flood control effects before and after the optimized layout schemes.Finally,the recommended layout optimization scheme of the detention areas is selected by comprehensive analysis.Results show that by adding Baishatang dike and Guanluchun dike as safety areas of Pajiang River Basin,the potential inundation cultivated area decreases by 163.2 hm² and the number of people prone to flood risks decreases by 3 002.This indicates the optimized layout scheme can reduce flood detention loss and ensure flood control safety.The results provide technical references and an approach for layout optimization of other detention areas.…”

RFreeTrack: RFID non-contact robust positioning system based on differential phase holography by Linqing GUI, Yi JIANG, Qingyun ZHANG, Fu XIAO

“…To address the issue of large positioning errors in complex environments within non-contact RFID-based positioning systems, RFreeTrack system was proposed.Commercial RFID equipment was used to calculate the reflected signals from targets, achieving high-precision non-contact positioning in complex environment.Firstly, a search method based on time-series similarity was proposed to employ for calibrating static signals, thus significantly enhanced the robustness of target reflection signal extraction.Secondly, a non-contact positioning method based on differential phase holography was introduced to eliminate the influence of the reader antenna’s position, thus the accuracy of positioning was improved and the complexity of system was deployment reduced as well.Finally, a high-precision non-contact positioning system prototype was realized.Experimental results indicate that in complex environments, the phase of the target reflection signals extracted using the calibrated static signals has a 68.8% lower error compared to existing methods.Based on the previously calibrated static reflection signals, the average positioning error using differential phase holography in complex environments is 0.040 8 m, and has a 50.6% improvement on location over existing methods.…”

Model of Electromagnetic Emitter Based on a Stream of Single Electrons inside Curved Carbon Nanotube by N. A. Poklonski, S. A. Vyrko, A. T. Vlassov, A. I. Siahlo, S. V. Ratkevich

“…The aim of the work is to find the possibility of application of injection and (quasi)ballistic drift of single electrons inside curved carbon nanotubes for emission of electromagnetic waves in the microwave range and to determine the parameters of the radiating system that affect the radiation power.By the calculation within the framework of classical electrodynamics it is shown the possibility in principle of generation of electromagnetic radiation of the gigahertz range by a stream of single electrons inside a hollow curved dielectric carbon nanotube.It was found that the spectrum and power of this radiation can be controlled by varying the electron flux density, length and curvature of the hollow nanotube.The results of the work can be applied for elaboration of a microminiature emitter of microwave electromagnetic radiation based on a curved carbon nanotube in the engineering of contactless probe microscopy.…”
