Via solving time-varying linear equations, this paper shows the Zhang dynamics (ZD) method. Besides, gradient (GD) method, which was originally designed for constant problems solving, is generalized equations solving. Then, ZD and GD methods are exploited together to solve tracking-control problem of a nonlinear system as new application. Simulation results on further demonstrate feasibility tracking control systems.
In this paper, a novel kind of new fractals, named Zhang is yielded by using the discrete-time complex-valued dynamics (DTCVZD) to solve nonlinear equations in complex domain. Such DTCVZD model designed based on elimination an indefinite error function, instead square-based non-negative energy function associated with gradient-based (DTCVGD). Comparing well-known (generalized) Newton fractals (i.e., famous generated iteration), we find that synthesized proposed incorporate such as special...
After widely investigating the velocity-level redundancy resolution schemes for redundant robot manipulators, we focus one of our research directions on relationship between different-level schemes, e.g., position-level and velocitylevel redundancy-resolution schemes. In this paper, propose a novel viewpoint; that is, there exists an equivalence some To demonstrate such viewpoint, two theoretical proofs, based gradient-descent method Zhang et al's neural-dynamic method, are presented in...
On a short to medium term, energy efficient retrofit LED products can offer an attractive solution for traditional lamps replacement in existing fixtures. To comply with user expectations, should not only have the same mechanical interface fit (socket and shape), but also similar light effect as they replace. The decorative lighting segment shows best conditions meet these requirements on term. In 2008, Philips Lighting Shanghai started development of candle lamp 15W Candle shape (B35 E14)...
This study evaluated the effect of preoperative ocular fixation training on patients undergoing pterygium surgery. Before excision, were trained to perform eye position training, which is beneficial for surgeons performing microsurgery. The analysed effectiveness in with by randomised controlled experimental design. number occurrences self-turning, operation time, self-rating depression scale scores and anxiety group (EG) lower than those control (CG). recurrence rate incidence conjunctival...
Due to the forming mechanism of SLM layer by stacking, low laser absorption rate and high thermal conductivity copper alloy, surface quality CuCrZr alloy porous structure formed is poor, which limits research application SLM. The effect plasma polishing technology on mechanical properties was investigated. Research has shown that after treatment, adhesion sample been significantly improved powder hidden between pores effectively removed. Combined with scanning electron microscopy, it found...
