Fretting wear has an adverse impact on the fatigue life of turbine blade roots. The current work is to comparatively investigate fretting behaviour nickel-based superalloy surfaces produced by polishing and creep-feed profile grinding, respectively, in terms surface/subsurface damage, friction coefficient, volume rate. Experimental results show that granulated tribolayer aggravates workpiece wear, while flat compacted enhances resistance ability workpiece, irrespective whether processed or...
In this study, an adaptive impact-time-control cooperative guidance law based on deep reinforcement learning considering field-of-view (FOV) constraints is proposed for high-speed UAVs with time-varying velocity. Firstly, a framework the UAVs’ problem established. The optimization objective to maximize impact velocity; and time, dive attacking, FOV are considered simultaneously. time-to-go estimation method improved so that it can be applied Then, in order improve applicability robustness of...
Abstract It is of great significance to study the stability foams in petroleum industry. Therefore, mechanism Span 20, fluorinated surfactant FCO‐80 and their mixture FS a CO 2 oil‐based foam system were studied by molecular simulation. The sandwich model was constructed reveal from microscopic perspective. result shows that under synergistic effect 20 FCO‐80, oil–CO distance coordination number oil molecules are larger than those system. In system, diffusion coefficients small, surface...
An impact point prediction (IPP) guidance based on supervised learning is proposed to address the problem of precise for ballistic missile in high maneuver penetration condition. accurate trajectory model applied generate training samples, and ablation experiments are conducted determine mapping relationship between flight state point. At same time, coordinates decoupled improve accuracy, sigmoid activation function improved ameliorate efficiency. Therefore, an IPP neural network model,...
Persistent cough is one of the most frequent complications following lung cancer surgery. To promote optimal recovery, we conducted a study to investigate trajectories coughing symptoms and their impact on quality life (QOL), as well identify potential risk factors persistent after pulmonary resection (CAP).This prospective observational assessed patients who underwent for tumor at two medical centers in China. CAP was evaluated before surgery, discharge, 1, 3, 6 months surgery using visual...
This paper proposes a novel framework for the online fault-tolerant control of hypersonic flight vehicles (HFV). The contains two steps. Firstly, based on Internet Things (IoT) and digital twin (DT) technology, vehicle (HFVDT) model is constructed. HFVDT can represent real parameter changes in HFV real-time, update itself by designed updating law through data acquired IoT. Then, caused fault be fed back real-time. Based real-time model, predictive static programming (MPSP) controller design...
Single-robot visual SLAM has problems such as slow mapping speed. This study proposed a multi-robot collaborative and scene reconstruction system based on an RGB-D camera. The adopts centralized structure. While several client robots collect image data respectively transmit the to server, server runs stand-alone ORB-SLAM2 for each client, stores real-time in map manager. At same time, it detects whether maps managers meet fusion conditions at certain frame rate, uses algorithm fuse when are...
The purpose of this study was to identify the potential risk and protective factors psychological burden in patients with pulmonary nodules (PNs) explore how status affects their treatment preferences.In questionnaire-based study, 1,185 outpatients were evaluated using Hospital Anxiety Depression Scale (HADS), correlations between patients' sociodemographic clinical characteristics assessed.Prevalence anxiety depression 42.1% 27.0%, respectively, among PNs. Binary logistic regression...
Anchor-based detectors have been continuously developed for object detection. However, the individual anchor box makes it difficult to predict boundary's offset accurately. Instead of taking each bounding as a closed individual, we consider using multiple boxes together get prediction boxes. To this end, paper proposes Box Decouple-Couple(BDC) strategy in inference, which no longer discards overlapping boxes, but decouples corner points these Then, according corner's score, couple select...
