In some video compressive sensing (CS) applications, the sparsity of original signals is unknown to sampling device. The computing power, memory space and power consumption device are also limited, which makes it difficult achieve adaptive rate (ARCS). A new blocked ARCS method for surveillance videos proposed, fully considers limitations mentioned above. By observing result CS measurement, statistical characteristics signal estimated. reasonably estimated by using these characteristics....
Demand response (DR) is counted as an effective method when there a large-capacity power shortage in the system, which may lead to peak loads or rapid ramp. This paper proposes bi-level coordinated optimization strategy by quantitating DR potential (DRP) of smart appliances descend steep ramp and balance energy. Based on dynamic characteristics appliances, mathematic models online DRP are presented. In upper layer, multi-agent distribution proposed allocate demand limit each agent from...
Polarization diversity has been widely used in maritime radars to improve target detection performance. Full utilization of the polarimetric characteristics sea clutter is key designing effective detectors. For high-resolution radars, HH-HV dual-polarization an affordable and mode monitor small targets, owing simple configuration single-polarimetric transmit dual-polarimetric reception lower powers at HH HV polarizations. Enlightened by analytical coherent detector compound-Gaussian with...
This paper presents an Improved PSO Algorithm (IPSO) to solve the problem of optimal Phasor Measurement Unit (PMU) placement. The aim Optimal PMU Placement is guarantee both full observability power grid and minimal number PMU. In Algorithm, point genetic algorithm simulated annealing process involved into basic particle swarm optimization. To deal with constraints, improved developed it can avoid costing much time trapping local solution. IEEE systems are tested show feasibility...
This paper addresses the secure communication problem in a distributed active-passive reconfigurable intelligent surface (RIS) assisted multiple-input single-output (MISO) scenario with single-antenna malicious eavesdropper. The objective is to maximize secrecy rate of legitimate user under constraints on base station (BS) power and RIS amplification coefficients. study investigates joint optimization algorithm for BS beamforming phase-shift matrices. To address complex non-convex fractional...
Pear black spot is caused by Alternaria tenuissima. It one of the diseases concern limiting pear production worldwide. Existing cultivation methods and fungicides are not sufficient to control early blight. Therefore, aim this study was isolate characterize two strains Streptomyces evaluate their potential for biological crop tenuissima while promoting plant growth. enriches resources biocontrol strains.
An adaptive rate Compressive Sensing (CS) method for video signals is proposed. The Blocked (BCS) scheme adopted in this method. Firstly, each frame blocked and measured by the BCS scheme, then mean variance of image block are estimated observing CS measurement results. Using block, sparsity can be classified. Adaptive sampling realized assigning different rates to classes. At same time, order make better use correlation between frames, a reference subtraction also designed paper, which uses...
When shipboard radar tracks low altitude targets above smooth sea surface, the phase wave front of arrival signal changes and performance low-angle tracking declines because multi-path propagation effects. A new algorithm interval search is proposed, which based on traditional mono-pulse phase-comparison method. This paper also investigates how to select right frequencies when frequency diversity used. Simulation results indicate that proposed method can efficiently improve angular...
Resource allocation management is the key issue of integrated network VLC and WiFi. In this paper, we discussed existing resource algorithms, proposed a novel algorithm based on proportional fairness (PF) algorithm, which improved ability users to obtain resources in different regions enhanced utilization rate resources. Finally, analyzed verify its effectiveness operability.
The gain characterization of photonic crystal fiber amplifier is theoretically and experimentally studied by using reverse pumping technique. curves for different powers signal lights are obtained experimentally. When the power probe light 6W pump 160W，the output up to 104W，has been achieved eventually. It found in experiment that when increased over a certain value，the evolves into unstable state，which turn degrades system performance.
In order to facilitate the computer simulation of radar sea clutter on complex surface and solve problem mismatch applicable conditions reflectivity models in high states, based measured data reflectivity, we analyze extendibility different state.
