In this work the Melnikov method for perturbed Hamiltonian wave equations is considered in order to determine possible chaotic behaviour in the systems. The backbone of the analysis is the multi-symplectic formulation of the unperturbed PDE and its further reduction to travelling waves. In the multi-symplectic approach two separate symplectic operators are introduced for the spatial and tempora...

Failure detectors are fundamental building blocks in distributed systems. Multi-node failure detectors, where the detector is tasked with monitoring N other nodes, play a critical role in overlay networks and peer-to-peer systems. In such networks, failures need to be detected quickly and with low overhead. Achieving these properties simultaneously poses a difficult tradeoff between detection l...

A novel function-link fuzzy cerebelarmodel-articulation-controller (CMAC) is developed in this study. It is a generalization of a fuzzy neural network and of a conventional CMAC. Then, a control system comprising a function-link fuzzy CMAC and a fuzzy compensator is proposed for multi-input multi-output (MIMO) nonlinear chaotic systems. The function-link fuzzy CAMC is used to mimic an ideal con...

In this paper we investigate the optimal latency of communications. Focusing on fixed rate communication without any feedback channel, this paper encompasses low-latency strategies with which one hop and multi-hop communication issues are treated from an information theoretic perspective. By defining the latency as the time required to make decisions, we prove that if short messages can be tran...

Performance debugging in production is a fundamental activity modern service-based systems. The diagnosis of performance issues often time-consuming, since it requires thorough inspection large volumes traces and indices. In this paper we present DeLag, novel automated search-based approach for diagnosing DeLag identifies subsets requests that show, the combination their Remote Procedure Call e...

This paper starts with a review of three-dimensional chaotic dynamical systems equipped special curves balance points. We also propose the mathematical model new system closed butterfly-like curve By performing bifurcation study system, we analyze intrinsic properties such as chaoticity, multi-stability, and transient chaos. Finally, carry out realization multi-stable using Field-Programmable G...

We present two systems that we have developed to aid geo-distributed web services deployed in the cloud to serve their users with low latency. First, CosTLO [23] helps mitigate the high latency variance observed when accessing data stored in multi-tenant cloud storage services. To cost-effectively satisfy a web service’s tail latency goals, CosTLO uses measurement-driven inferences about replic...
