二月之盛事,莫过于北京冬奥会,来自全世界的冰雪健儿争金夺银,全力以赴的比赛场景看得人心潮澎湃,一些直播画面至今记忆犹新.在双人滑自由金牌比赛中,最后一组出场的隋文静和韩聪面对强大的劲敌,顶着巨大的压力完成比赛,看着他们相拥而泣的那一刻,屏幕前的自己也瞬间泪目.

In this paper, an intelligent fractional-order integral sliding mode control (FOISMC) strategy based on an improved cascade observer is proposed. First, an FOISMC strategy is designed to control a permanent magnet synchronous motor. It has good tracking p
Because it is magnet-free and can achieve a high integration level, the switched-capacitor (SC) converter acting as a direct current transformer has many promising applications in modern electronics. However, designing an SC converter with large current c
In constructing a smart court, to provide intelligent assistance for achieving more efficient, fair, and explainable trial proceedings, we propose a full-process intelligent trial system (FITS). In the proposed FITS, we introduce essential tasks for const
To avoid Doppler ambiguity, pulse Doppler radar may operate on a high pulse repetition frequency (PRF). The use of a high PRF can, however, lead to range ambiguity in many cases. At present, the major efficient solution to solve range ambiguity is based o
Deep learning has proven to be an effective mechanism for computer vision tasks, especially for image denoising and burst image denoising. In this paper, we focus on solving the burst image denoising problem and aim to generate a single clean image from a
Since traditional machine learning methods are sensitive to skewed distribution and do not consider the characteristics in multiclass imbalance problems, the skewed distribution of multiclass data poses a major challenge to machine learning algorithms. To
Robots need more intelligence to complete cognitive tasks in home environments. In this paper, we present a new cloud-assisted cognition adaptation mechanism for home service robots, which learns new knowledge from other robots. In this mechanism, a chang
1 IntroductionrnA compact ultra-wideband crossed-dipole an-tenna is proposed for 2G/3G/4G/IMT/5G customer premise equipment (CPE) applications. The arms of the crossed-dipole antenna are formed by step-shaped patches, and a wideband operation can be reali

Threshold proxy re-encryption (TPRE) can prevent collusion between a single proxy and a delegatee from converting arbitrary files against the wishes of the delegator through multiple proxies, and can also provide normal services even when certain proxy se
For flow-related design optimization problems, e.g., aircraft and automobile aerodynamic design, com-putational fluid dynamics (CFD) simulations are commonly used to predict flow fields and analyze performance. While important, CFD simulations are a resou
