This paper is devoted to stability analysis and synthesis of the linear systems with time-varying delays. Some new stability conditions are developed for the systems based on Lyapunov-Razumikhin theorem. Then a design method for the general state feedback controllers is proposed for the systems with multiple delays by the LMI optimization based approach. Numerical examples are used to demonstra...

For a family of differential equations with infinitive delay and impulses, we establish conditions for the existence of global solutions and for the global asymptotic and global exponential stabilities of an equilibrium point. The results are used to give stability criteria for a very broad family of impulsive neural network models with both unbounded distributed delays and bounded time-varying...

The approach presented in this paper aims to obtain a QoS for IPv6 protocol over LEO satellites. Most of the switching and access operations in the proposed system will require the intelligent functions to be located on earth. We can allocate links at different bit-rates and no particular assumptions have been made as concerns the access protocol in order to maintain the presented work at a gen...

Let A∗ be a free monoid generated by a set A and let X ⊆ A∗ be a code with property P. The embedding of X into a complete code Y ⊆ A∗ with the same property P is called the completion of X . The method of completion of rational bi!x codes and codes with !nite decoding delays have been investigated by a number of authors. In this paper, we provide a general method of construction for completing ...

We analyze stability of consensus algorithms in networks of multi-agents with time-varying topologies and delays. The topology and delays are modeled as induced by an adapted process and are rather general, including i.i.d. topology processes, asynchronous consensus algorithms, and Markovian jumping switching. In case the self-links are instantaneous, we prove that the network reaches consensus...

A lack of available blood contributes to 16% of all maternal deaths in Egypt. This study aimed to assess the quality of care for obstetric emergencies in 4 general hospitals in Egypt over a 6-month period with the focus on delays in receiving care and blood bank services. Observations were made of the processes and delays in the clinical setting, from the start of each patient's complaint until...

For solving problems of TCP in a long-fat network, a transport-layer protocol called XCP (eXplicit Control Protocol) has been proposed. XCP aims at realizing efficient congestion control by sending explicit feedback information from a router to source hosts. In the literature, there have been several simulation experiments for evaluating performance of XCP. However, stability of XCP in a genera...

The purpose of this paper is to study a class of differential]difference equations with two delays. First, we investigate the local stability of the zero solution of the equation by analyzing the corresponding characteristic equation of the linearized equation. General stability criteria involving the delays and the parameters are obtained. Second, by choosing one of the delays as a bifurcation...

BACKGROUND Fundamental measures of control of tuberculosis are early detection and timely treatment of the affected. The aim of this study was to identify factors associated with patient-related and health system-related delays among patients with tuberculosis in the Republic of Montenegro. METHODS A cross-sectional study included 130 tuberculosis patients older than 15 years of age. The incl...

a second-order leader-following consensus algorithm in multi-agent systems with directed network topologies and heterogeneous input delays, which generalized the previous work [1] from the case of symmetric coupling weights to that of asymmetric coupling weights. Some sufficient conditions for reaching second-order consensus in a leader-following context were derived by utilizing the Gershgorin...
