A new approach to stability analysis of neural networks with time-varying delay via novel Lyapunov-Krasovskii functional

引用

Chinese Physics B 2010年第5期19卷 115-120页

作者： S.m.Lee O.m.Kwon Ju H.Park department of Electronic Engineering Daegu UniversityGyungsanGyungbuk 712-714Republic of Korea College of Electrical and Computer Engineering 410 SungBong-RoHeungduk-GuChungbuk National UniversityCheongju 361-763Republic of Korea Nonlinear dynamics Group Department of Electrical EngineeringYeungnam University214-1 Dae-DongKyongsan 712-749Republic of Korea

In this paper, new delay-dependent stability criteria for asymptotic stability of neural networks with time-varying delays are derived. The stability conditions are represented in terms of linear matrix inequalities （LmIs） by constructing new Lyapunov-Krasovskii functional. The proposed functional has an augmented quadratic form with states as well as the nonlinear function to consider the sector and the slope constraints. The less conservativeness of the proposed stability criteria can be guaranteed by using convex properties of the nonlinear function which satisfies the sector and slope bound. Numerical examples are presented to show the effectiveness of the proposed method.

The Effect of different Formulations on Turnip Juice Production in Controlled Conditions

Black carrots （daucus earota L. spp. sativus. ） were fermented for 4 weeks by using six different starter dough formulations. Some of the samples were pasteurized to detemaine the effects of heat treatment on fermentation. Fermentation was followed by physicochemical and microbiological analysis. Some characteristics such as dry matter, crude fiber, water soluble extract, alcohol soluble extract, ether soluble extract, crude energy, total sugar, pH, salt and colour values and mineral contents of black carrot were determined. In the beginning of the fermentation, dry matter is highest in the brines with coriandrium and dry matter of the other brines are close to each other and lower than that of the brines with coriander. The number of Lactic acid bacteria, total bacteria, moulds-yeasts and coliform bacteria decreased through the end of fermentation. Heat treatment had a considerable effect on microbial growth. The microbial growth was higher in the nnpastenrized samples. Total bacteria number reached the highest level for the pasteurized samples （ 104 cfu/mL - 105 cfu/mL ） and for the unpasteurized samples （106 cfu/mL - 107 cfu/mL） in the second day. After the fermentation, sensory analyses were carried out to determine the storage stability of the last products. While ＂a＂ value increased, ＂b＂ and ＂L＂ values decreased during storage time. Yoghurt inoculated brine were preferred from the colour, odour and acceptability points of view.

Quantum monty Hall Problem under decoherence

引用

Communications in Theoretical Physics 2010年第7期54卷 47-54页

作者： Salman Khan m.Ramzan m.K.Khan department of Physics Quaid-i-Azam University

We study the effect of decoherence on quantum monty Hall problem under the influence of amplitude damping, depolarizing, and dephasing channels. It is shown that under the effect of decoherence, there is a Nash equilibrium of the game in case of depolarizing channel for Alice＇s quantum strategy. Whereas in case of dephasing noise, the game is not influenced by the quantum channel. For amplitude damping channel, Bob＇s payoffs are found symmetrical about a decoherence of 50% and the maximum occurs at this value of decoherence for his classical strategy. However, it is worth-mentioning that in case of depolarizing channel, Bob＇s classical strategy remains always dominant against any choice of Alice＇s strategy.
