Light emitting diodes become brighter because of the contribution of patterned sapphire substrates (PSS). The dimensions of PSS crucially affect its performance. The most suitable instrument to measure PSS is atomic force microscope, which provides three-dimensional surface profiles. This paper proposes an automatic method to analyze AFM-collected raw data and produce characteristic parameters of...
A nonlinear intelligent reentry control method with B-spline functional link network disturbance observer (BFLNDO) is presented for hypersonic vehicles (HSVs). The nonlinear generalized predictive control (NGPC) algorithm is employed to design the nominal control law of the attitude system of the HSV. The output prediction defined on finite horizon is carried out via Taylor series expansion. The unmodeled...
Evaluation is significant tool for contractor equipment maintenance support construction, and also a primary mean to reflect construction effect objectively and accurately. This paper presents basic theory and methods of System Dynamics at first. Then the elements and structure of contractor equipments maintenance support construction system are analyzed, which is help to describe the control relationship...
In information fusion system, many algorithms that possess performance characteristics are existed to solve a single problem. The usual approach in this situation is to manually select the algorithm which has the best average performance. However, this strategy has drawbacks when the whole information fusion procedure is divided into several steps. This paper presents a modeling method that uses Markov...
Before the socializing reform of university logistics, it was mainly self-employed and non-profit oriented, which caused more managing costs and serious waste of resources. After the implementation of the socializing reform, many universities cannot control the scale of the reform. As a result, the side effect of marketing evidently shows up. Some operators of the logistic service project put profit...
Aim at robustness and efficiency of traditional Dynamic Graph Watermark (DGW), a DGW-AB algorithm based on threshold scheme is proposed, in which the idea of secret sharing to the software watermarking is introduced. Experimental results have shown that the proposed method can make up the weakness of CT algorithm, and prevent invaders from getting the original watermark.
