This paper presents the design of a flexible bending actuator using shape memory alloy (SMA) and its integration in attitude control for solar sailing. The SMA has advantages power-to-weight ratio light weight. mechanism models were designed developed. A neural network based adaptive controller was implemented to non-linear nature actuator. modules integrated into sail model with quaternion PD that formed cascade control. feasibility performance proposed investigated evaluated, showing could...
Based on the social interdependence theory, we proposed that distributive justice climate affects virtual team performance via high-quality relationships, and then investigated boundary effect of proactive personality. The data used in this study were collected China, including 327 members belonged to 75 teams. following results are obtained: (1) Distributive relationships have significant positive effects performance. (2) High-quality mediate relationship between (3) Team personality...
In this paper, a liquid reconfigurable stealth window constructed by metamaterial absorber at the microwave band is proposed. The consists of an anti-reflection glass with indium tin oxide (ITO) as resistive film and container made polymethyl methacrylate (PMMA). Since materials constituting are all optically transparent, metamaterials that can be switched through control system always maintain high light transmission. proposal obtain transmission passband from 2.3 GHz to 5 low insertion...
The application of deep learning to the detection gravitational wave (GW) signals has attracted much attention in recent years, and nearly all existing learning-based GW algorithms are based on convolutional neural network (CNN), which can be used identify merger moment produce responding triggers. However, current CNN-based models not best optimized tools modeling causal logic sequential data time dimension incorporate information inspiral, ringdown phases waveform. To address this issue we...
Synthetic aperture radar(SAR) ship target detection plays an increasingly important role in marine monitoring. Aimed at the problems of recognizing small size targets SAR images and inability traditional methods to extract fine features due external disturbances, we propose improved model based on deep learning technology. The proposed mainly consists two parts:region proposal network(RPN) object network. Firstly, a CNN is designed trained accurately identify targets. Then, used initialize...
In this paper, we present a four-layer tunable wideband electromagnetic shield based on cold plasma. It consists of two dielectric matched layers, one backside housing layer and vacuum chamber in between where plasma can be produced through glow discharge. No is within the when low-power communication signal impinges it easily propagate with very low return absorption loss. When high-power microwave pulse shield, timely to reflect absorb high-intensity energy. Input impedance, standing wave...
The popularity of smart phones has brought significant convenience to people’s lives, but also there are many security problems. In recent years, malicious applications increasingly rampant, which threaten users and society as challenges network reliability management. However, due neglecting the sequential features between flows, existing application recognition methods based on traffic analysis have low accuracy. Based characteristics Android applications, this paper firstly applies Long...
A hybrid dielectric resonator antenna (DRA) array is proposed for the wideband millimeter-wave communication. The radiator composed with a pair of stacked resonators (DRs), which are H-shaped and Hexagon-shaped DRs, respectively. dual-slots on substrate integrated waveguide (SIW) cavity utilized higher mode generation in DRA element. bandwidth improved by DRs dual-slot feeding. structural characteristics key parameters feeding slots discussed detail. fed parallel power distribution network...
In order to meet the demand of high capacity and speed transmission satellite communication system, a wideband dual-circularly polarized dielectric resonator antenna (DRA) array is proposed based on traveling wave principle. Four DRA elements with slot-coupling excitation are sequentially placed ground, feeding network designed realize two orthogonal circular polarization radiation waves. A notched copper loop (NCL) around adopted improve performance. Depending operation ports, NCL generates...

It is known image priors are essential to blind deconvolution. Reweighted graph total variation (RGTV), as a new prior substitute the most classic TV, shown superior TV well several other state-of-the-art models in terms of both theoretical and empirical performance. In this paper, we take step forward providing simpler geometric view RGTV, instead previous spectral interpretation made frequency domain. specific, formulate deblurring just via use derivative Leclerc loss, which geometrically...
