The satisfiability problem is the first problem proved to be NP-Complete and has been one of the core NP-Complete problems since then. The satisfiability problem is a decision problem. And the maximum satisfiability problem is its optimization version that aims to find an assignment that satisfies most clauses. In this study, a fuzzy conversion method is proposed to convert the maximum satisfiability...
This paper presents dynamic surface control for longitudinal dynamics of a generic hypersonic flight vehicle in presence of unknown dynamics. For the attitude subsystem, the minimal-learning-parameter technique is combined with dynamic surface design. The uniform ultimate boundedness stability is guaranteed via Small-gain Theorem. The singularity problem is removed and the simpler adaptive algorithm...
We propose a hybrid C+L band fiber amplifier loop-back scheme. It is composed of a C-band erbium-doped fiber amplifier (EDFA) and an L-band Raman fiber amplifier (RFA) using double-pass dispersion compensators in a loop-back scheme. Dispersion slope mismatch precisely compensates for all C+L band channels by writing fiber Bragg gratings (FBGs) at appropriate locations. Gain variation among multiple...
In this paper, the dual of a novel martingale Hardy space generated by α-mean-square operator is addressed. Fefferman's inequality is proved to hold for 1 ≤ α ≤ 2 and 1 ≤ p ≤ α. Meanwhile, the dual space of HpSα is characterized and proved in the case. The result shows that for 1 ≤ α ≤ 2 and 1 ≤ p ≤ a , the dual space of HpSα can be characterized by Garsia space αKp.
For some difficult problems, artificial neural network (ANN) ensemble classifiers, instead of a single ANN classifier, are considered. The ensemble usually has better generalization performance than any individual network for classification problems. But, it is not easy to construct the ANN ensemble. In the previous study, the authors presented the systematic trajectory search algorithm (STSA) to...
Application layer multicast (ALM) has resolved the issue of deployment, but effectiveness inferiors to IP multicast. In this paper, the research is focused upon the influence on the communication efficiency of the multicast tree using three kinds of node selection strategy, which are based on min-delay, max-bandwidth, and nearest network topology. This paper presents NNT, a distributed spanning tree...
Image hiding techniques embed a secret image into a cover image. The fusion of the two, called a stego- image, fools grabbers who would not be conscious of the differences between the cover image and. the stego- image. A secret image can be transferred safely using this technique. In general, we would disarrange each pixel in the secret image and adjust all of them to form a suitable string of bits...
