Many real-world classification problems are characterized by samples of a complex distribution in the input space. The accuracy is determined intrinsic properties all subspaces features. This paper proposes novel algorithm for construction radial basis function neural network (RBFNN) classifier based on subspace learning. In this paper, feature obtained every hidden node RBFNN during learning process. connection weights between layer and adjusted to produce various with dominative features...
In this paper, an improved joint time-frequency (TF) analysis method based on a reassigned smoothed pseudo Wigner–Ville distribution (RSPWVD) has been proposed in interference detection for Global Navigation Satellite System (GNSS) receivers. the RSPWVD, two-dimensional low-pass filtering smoothing function is introduced to eliminate cross-terms present quadratic TF distribution, and at same time, reassignment adopted improve concentration properties of auto-terms signal components. This...
With a fuzzy analytic hierarchy process, the of risk factors in satellite general-assembling process is established, based on which, weights various are determined one by one. Furthermore, quantitatively analyzed, and comprehensive assessment model established end. Taking as an example, risks assessed comprehensively, levels measured. The sorted according to their impact capabilities overall level, key points control for clarified. Results obtained from analysis sub-factors suggested that...
Abstract The robots with low stiffness are prone to chatter during countersinking, which inevitably reduces the accuracy of countersink depth. In this paper, a method for decreasing robotic system is proposed by combining countersinking and longitudinal-torsional composite ultrasonic machining technology. Through comparative study common (RCC) (RCUC-LT) experiments, feasibility effectiveness introducing vibration improve quality CFRP/Al stack have been proven from three aspects: cutting...
Objective: The study contributes to human reliability analysis (HRA) by proposing a method that focuses more on error causality within sociotechnical system, illustrating its rationality and feasibility using case of the Minuteman (MM) III missile accident. Background: Due complexity dynamics previous analyses accidents involving organizational factors clearly demonstrated methods sequential accident model are inadequate analyze system. Methods: System-theoretic processes (STAMP) was used...
Functional Resonance Analysis Method (FRAM), which defines a systemic framework to model complex systems from the perspective of function and views accidents as emergent phenomenon function’s variability, is playing an increasingly significant role in development accident theory. However, FRAM typically taken theoretic method, there lack specific approaches or supportive tools bridge theory practice. To fill gap contribute FRAM, (1) variability was described further, with rules interaction...
Abstract Ground localization systems based on cellular signals are vulnerable to the hazards of signal power attenuation and multipath propagation in urban environments. Non-coherent accumulation is an effective solution this problem, but its application has not been properly discussed. In paper, we propose two time-of-arrival (TOA) estimation methods non-coherent accumulation: “TOA algorithm channel impulse response” (nch-CIR) time domain “Super Resolution TOA Estimation Algorithm...
In this study, we design an embedded surface EMG acquisition device to conveniently collect human signals, pursue more intelligent human–computer interactions in exoskeleton robots, and enable robots synchronize with or even respond user actions advance. The has the characteristics of low cost, miniaturization, strong compatibility, it can acquire eight-channel signals real time while retaining possibility expanding channel. This paper introduces function detail, which includes use wired...
