Time Delays in Cosmic Ray Propagation

Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...

FINITE-TIME PASSIVITY OF DISCRETE-TIME T-S FUZZY NEURAL NETWORKS WITH TIME-VARYING DELAYS

This paper focuses on the problem of finite-time boundedness and finite-time passivity of discrete-time T-S fuzzy neural networks with time-varying delays. A suitable Lyapunov--Krasovskii functional(LKF) is established to derive sufficient condition for finite-time passivity of discrete-time T-S fuzzy neural networks. The dynamical system is transformed into a T-S fuzzy model with uncertain par...

Vector quantization with transmission energy allocation for time-varying channels

This work is concerned with the problem of designing robust, vector quantizer (VQ)-based communication systems for operation over time-varying Gaussian channels. Transmission energy allocation to VQ codeword bits, according to their error sensitivities, is a powerful tool for improving robustness to channel noise. The power of this technique can be further enhanced by appropriately combining it...

Propagation Redundancy for Permutation Channels

Finding a good model of a constraint satisfaction problem (CSP) is a challenging task. A modeller must specify a set of constraints that capture the definitions of the problem, and the model should also have strong propagation. In other words, the model should be able to quickly reduce the domains of the variables of the problem, and the implementation of these propagators should be efficient, ...

Remote Output Stabilization Under Two Channels Time-Varying Delays

In this paper we investigate the problem of remote output stabilization via two channels time-varying delays. This problem arises when the control law is remotely implemented. The exchange of data between the controller and the system is done via two different transmission channels introducing time-varying delays with known dynamics. Assuming a known model for each of the time-delay dynamics, t...
