the paper is concerned with robust stability criteria for takagi- sugeno (t-s) fuzzy systems with distributed delays and time delay in the leakage term. by exploiting a model transformation, the system is converted to one of the neutral delay system. global robust stability result is proposed by a new lyapunov-krasovskii functional which takes into account the range of delay and by making use o...

A traditional query returns a set of objects that satisfy user defined criteria at the time query was issued. The results are based on the values of objects at query time and may be affected by outliers. Intuitively, an object better meets the user’s needs if it persistently satisfies the criteria, i.e., it satisfies the criteria for majority of the time in the past T time units. In this paper,...

In this paper, the synchronization problem of uncertain neutral-type neural networks (NTNNs) with sampled-data control is investigated. First, a mixed-delay-dependent augmented Lyapunov–Krasovskii functional (LKF) proposed, which not only considers interaction between transmission delay and communication delay, but also takes interconnected relationship neutral into consideration. Then, two-sid...

Criteria are established for existence of positive solutions to the second order periodic boundary value problem −u(t) + pu(t) + p1u(t) = f(t, u), t ∈ I = [0, T ], u(0) = u(T ), u(0) = u(T ), where p ∈ R and p1 ≥ 0. The discussion is based on the fixed point index theory in cones. AMS Subject Classification: 34B18

In this paper, by using a linking theorem, some new existence criteria of homoclinic orbits are obtained for the p-Laplacian system d(|u̇(t)|p−2u̇(t))/dt + ∇V (t, u(t)) = f(t), where p > 1, V (t, x) = −K(t, x) + W (t, x).

New oscillation criteria are established for the nonlinear matrix differential equations with a forced term [r(t)Y ′(t)]′ + p(t)Y ′(t) + Q(t)G(Y ′(t))F (Y (t)) = e(t)In. Our results extend and improve the recent results of Li and Agarwal for scalar cases. Furthermore, one example that dwell upon the importance of our results is included.

Research in soccer has traditionally given more weight to players' technical and tactical skills, but few studies have analyzed the motor skills that underpin specific motor actions. The objective of this study was to investigate the style of play of the world's top soccer players, Cristiano Ronaldo and Lionel Messi, and how they use their motor skills in attacking actions that result in a goal...

We consider forced second order differential equation with p-Laplacian and nonlinearities given by a Riemann-Stieltjes integrals in the form of ( p(t)φγ ( x′(t) ))′ + q0 (t)φγ (x(t)) + ∫ b 0 q (t, s)φα(s) (x(t)) dζ (s) = e(t), where φα (u) := |u| sgnu, γ, b ∈ (0,∞) , α ∈ C [0, b) is strictly increasing such that 0 ≤ α (0) < γ < α (b−), p, q0, e ∈ C ([t0,∞),R) with p (t) > 0 on [t0,∞), q ∈ C ([0...

This paper presents some solvability criteria for the second order nonlinear equation (p(t)u′(t))′ − q(t)u(t) = f ( t, ∫ t 0 u(s)ds, u′(t) ) , t ∈ (0, 1), with one of the following boundary conditions au(0)− bp(0)u′(0) = 0, cu(1) + dp(1)u′(1) = μ1u(ξ), au(0)− bp(0)u′(0) = μ2u(ξ), cu(1) + dp(1)u′(1) = 0, au(0)− bp(0)u′(0) = μ1u(ξ), cu(1) + dp(1)u′(1) = μ2u(ξ).
