In this paper, we propose a cognitive approach to design phase-only modulated waveforms sharing a desired range-Doppler response. The idea is to minimize the average value of the ambiguity function of the transmitted signal over some range-Doppler bins, which are identified exploiting a plurality of knowledge sources. From a technical point of view, this is(More)
Global asymptotic stability problem is studied for a class of recurrent neural networks with distributed delays satisfying Lebesgue-Stieljies measures on the basis of linear matrix inequality. The concerned network model includes many neural network models with various delays and structures as its special cases, such as the delays covering the discrete(More)
The stem of the creeping Chrysanthemum morifolium Ramat. cultivar ‘Yuhuajinhua’ responds to a gravitational stimulus by bending. Most of the calcium ion (Ca2+) present in the stem cells was concentrated in the cell walls, intercellular space, and vacuoles, with very little in the cytoplasm. An investigation of the effects of supplying exogenous Ca2+ or the(More)
In this paper, we propose a cognitive approach to design phase-only modulated waveforms sharing a desired ambiguity function. We formulate the problem as a quartic order polynomial optimization problem with a constant modulus constraint on each variable. Thus, we devise an optimization procedure based on the Maximum Block Improvement (MBI) approach. At the(More)
The character of branching for two chrysanthemum (Chrysanthemum × morifolium) cvs. Jinghai and Jingyun was observed, and the changes of endogenous hormones in apical and lateral buds were investigated to determine the relationship between the pattern of hormone distribution, apical dominance, and lateral bud outgrowth. The growth rate of Jinghai lateral(More)
This paper proposes a new customized proximal point algorithm for linearly constrained convex optimization problem, and further extends the proposed method to separable convex optimization problem with linear constraints. The global convergence and a worst-case convergence rate of the proposed methods are proven under some mild assumptions. Preliminary(More)
The performance of port-starboard discrimination (PSD) for a target detected by a towed twin-line sonar array is presented. The PSD performance is evaluated by a measure referred to as the port-starboard rejection ratio (PSRR), which is defined as the ratio of the output power in the desired signal direction to that in the mirror direction. Analytical(More)
