Beyond-visual-range (BVR) engagement becomes more and popular in the modern air battlefield. The key difficulty for pilots fight is maneuver planning, which reflects tactical decision-making capacity of both sides determinates success or failure. In this paper, we propose an intelligent planning method BVR combat with using improved deep Q network (DQN). First, a basic environment builds, mainly includes flight motion model, relative model missile attack model. Then, create decision...
Abstract Background Volatile organic compounds (VOCs) encompass hundreds of high production volume chemicals and have been reported to be associated with adverse respiratory outcomes such as chronic obstructive pulmonary disease (COPD). However, research on the combined toxic effects exposure various VOCs COPD is lacking. We aimed assess effect VOC metabolite mixture risk in a large population sample. Methods assessed 5997 adults from National Health Nutrition Examination Survey (NHANES)...
The immune mechanisms of long coronavirus disease 2019 (COVID) are not yet fully understood. We aimed to investigate the severe acute respiratory syndrome 2 (SARS-CoV-2)-specific memory responses in discharged COVID-19 patients with and without COVID symptoms. In this cross-sectional study, we included 1041 hospitalized original virus strain Wuhan (China) 12 months after initial infection. simultaneously conducted a questionnaire survey collected peripheral blood samples from participants....
In this paper, a novel event-triggered optimizing consensus tracking control scheme is proposed for multiple unmanned aerial vehicles (UAVs) formation. First, the formation transformed to an optimal issue based on feedforward- feedback design framework. Subsequently, policy iteration algorithm developed solve input-constrained Hamilton-Jacobi-Isaacs (HJI) equation two-player zero-sum differential game. The critic-only architecture adopted approximate cost function. A weight vector tuning law...
Non-linear friction and external disturbances affect the positioning accuracy of high-speed motion systems, especially those impelled by linear motors. This paper presents a controller, which includes three parts: proportional-plus-derivative (PD) feedback compensator, disturbance observer. The compensator is based on LuGre model compensates for non-linear friction. observer used to eliminate compensation error other disturbances. Experimental results show that controller gives high robust...
A novel adaptive fuzzy dynamic surface control (DSC) scheme is for the first time constructed a larger class of (multi‐input multi‐output) MIMO non‐affine pure‐feedback systems in presence input saturation nonlinearity. First all, restrictive differentiability assumption on functions has been canceled after using piecewise to reconstruct model nonlinear functions. Then, auxiliary system with bounded compensation term firstly introduced deal saturation, and employed this work designs tangent...
A novel set-invariance adaptive neural dynamic surface (DSC) control scheme is presented for an extended class of the periodically disturbed nonlinear MIMO strict-feedback systems whose gain functions are possibly unbounded. The most advanced that restrictive bounds assumption removed after introducing appropriate compact sets, which constructed in such a way all closed-loop trajectories stay those sets time. To tackle tracking problem presence more general periodic disturbances, function...
Due to possible disturbances in a conflict environment, the mission performance of flying ad hoc networks (FANET) is highly related time-varying topology. Currently, resilience metric regarded as suitable for evaluating FANET with network However, reported studies contribute little theoretical analysis impact topology on cooperative mission. In this article, an improved method proposed by defining new dimension reduction operator, which takes into account impacts both isolated and...
Data mining technology is the process of extracting hidden knowledge and potentially useful information from a large number incomplete, noisy, random practical application data. The clustering algorithm based on multi-objective evolution has obvious advantages compared with traditional single-objective method. In order to further improve performance evolutionary algorithms, this paper proposes automatic model multi-task optimization. Based that automatically determines value k, optimization...
The development of welding technology for zirconium alloy has great significance on the safety, stability, and reliability operation nuclear reactor.

Summary Most current medical images are collected in the presence of interference by ignored interferences such as illumination, occlusion, etc. The recognition rate is low for multi‐resolution case color distortion. Therefore, a novel fuzzy clustering algorithm image was proposed this paper. First, were analyzed from both acquisition time, shooting angle, resolution, natural light measurement, and background. Secondly, order to avoid partial region recalculated correlation between Fourier...
