This paper reports on an analysis of the thermal performance a linear fresnel reflector concentrator (LFRC) with compound parabolic cavity (CPC) absorber. A steady-state heat transfer model is developed for concentrator, while network used to investigate radiative within CPC. Simulation results indicate that collector temperature increases along receiver tube length. It also shown overall loss predominated by from glass pane ambient. In addition, show key factors influence this type include...
Abstract Spectral observations with high temporal and frequency resolution are of great significance for studying the fine structures solar radio bursts. In addition, it is helpful to understand physical processes eruptions. this paper, we present design a system observe bursts resolutions at frequencies 25–110 MHz. To reduce impact analog devices improve flexibility, employ various digital signal processing methods achieve function devices, such as polarisation synthesis beamforming. The...
To achieve low threshold current as well high single mode output power, a graded index separate confinement heterostructure (GRIN-SCH) AlGaInAs/AlGaAs quantum laser with an optimized ridge waveguide was fabricated. The reduced to 8 mA. An power of 76 mW achieved at 100 mA room temperature, slope efficiency 0.83 W/A and horizon divergent angle 6.3°. maximum the device reached 450 mW.
A trapezoidal cavity absorber for a linear Fresnel reflector concentrator is analyzed and optimized via CFD simulation. The heat loss coefficient introduced; the influences of ambient temperature, depth, inclination side walls, insulation thickness, glass window, emissivity selective absorption coating have been studied. results show that radiation dominates loss, through window higher than layer; among these factors, impact layer greater other factors. simulation prove with 100 mm depth...
We develop an end-to-end workflow for the training and implementation of co-designed neural networks (NNs) efficient field-programmable gate array (FPGA) application-specific integrated circuit (ASIC) hardware. Our approach leverages Hessian-aware quantization (HAWQ) NNs, Quantized Open Neural Network Exchange (QONNX) intermediate representation, hls4ml tool flow transpiling NNs into FPGA ASIC firmware. This makes NN implementations in hardware accessible to nonexperts, a single open-sourced...
Time-frequency synchronization plays an important role in the construction of solar radio telescopes (such as heliograph and interferometry). In development a system, time-frequency signal is divided transmitted to each antenna array, therefore, performance splitting devices determines quantity data. To address this situation, we designed frequency transmitting conducted test compare phase difference among outputs (10 MHz - 1.4 GHz), deterioration stability 1GHz) brought by different (fiber...
A compressor-driven chemisorption system with a gas cooler (CDCSGC) operating in time-delay cycle is proposed for the purpose of enhancing compressed heat transfer and recovering part pressure energy. The CDCSGC using basic cycles then mathematically simulated, influence various parameters, including volumetric displacement rate (Ucom), area (Agc), time (tbc), process (ttd) on specific cooling power (SCP) coefficient performance (COP) studied. Compared to conventional that uses cycle, not...

A compressor-driven adsorption refrigeration system that uses graphite-BaCl2 composite adsorbent/ammonia as a working pair has been investigated through dynamic optimization. The main purposes of this work were to obtain the optimal volume flow rate profile with cycle time and improve COP SCP simultaneously. general multiobjective optimization mathematical model presented, then shrinked single goal problem by weighted sum method. Because was not specified, normalized variable introduced...
Enterovirus 71 (EV71) is one of the important pathogens hand, foot and mouth disease (HFMD) in infants young children. It also a very common virus after poliovirus which associated with severe acute neurological disease. Mutations or spatial structure changes untranslated regions (UTRs) may affect ability to translate replicate, as well affinity for cellular tissue, even lead virulence. At present, pathogenic mechanism EV71 still unknown, study an indispensable part. Here we briefly review...
Objective To sequence the 3′UTR of enterovirus 71 strains, investigate its foundation and impact in virulence by constructing a 3′UTR-replaced recombinant cDNA infectious clone. Methods Viral RNA EV-A71 isolated viruses were extracted, nucleotide analysis was performed after sequencing. The full-length clone SDLY107 strain replaced corresponding part SDLY1 strain, then virus constructed identified. Results The nine strains classified into sub-genotype C4a (EV)-A71 analysis,...
