In this paper we propose a generalized complex networks model, which concerns asymmetric network configuration including both neutral-type coupling delay and retarded-type one. The synchronization problem of this generalized complex networks is reformulated into the asymptotical stability problem of neutral delay functional differential equations. By introducing descriptor system transformation...

In this paper we deal with the observer-based asymptotic synchronization problem for a class of chaotic oscillators. Some results based on a differential algebraic approach are used in order to determine the algebraic observability of unknown variables. The strategy consists of proposing a slave system (observer) which tends to follow asymptotically the master system. The methodology is tested ...

An opposed hydraulic free piston engine is under design at the Tianjin University in China because of the advantages of this engine compared to the conventional engine. The main challenges presented by such engines are the control of the piston motion and synchronization. This study investigates the fundamental control context and control method of the opposed hydraulic free piston engine using...

During standing posture, the soleus muscles acts to control sway in the anteroposterior (AP) direction. The soleus muscles bilaterally share a common function during standing tasks. We sought to determine whether common descending inputs, as evidenced by the synchronization of bilateral motor unit pairs, were employed as a strategy to control this common function. Single motor units were record...

One of the basic tenets in recent international trade literature is about the effect of trade integration on business cycle synchronization (BCS) among trading countries. The objective of this paper is to explore the main determinants of business cycle synchronization, with emphasis on trade integration. To this end, we have specified two simultaneous regression equations which were estimated b...

In the past years, impulsive control for a single system and impulsive synchronization between two systems have been extensively studied. However, investigation on impulsive control and synchronization of complex networks has just started. In these studies, a network is continuously coupled, and then is synchronized by using impulsive control strategy. In this paper, a new and different coupled...

Blind Synchronization for Multi-rate DS-CDMA Systemsy Zhouyue Pi and Urbashi Mitra Department of Electrical Engineering The Ohio State University, Columbus, OH 43210 e-mail:fpiz,[email protected] Abstract The synchronization problem of multi-rate asynchronous DS-CDMA systems is investigated. Both subspace and non-parametric methods are considered for two types of multi-rate access sch...

Physical constraints such as power, leakage and pin bandwidth are currently driving the HPC industry to produce systems with unprecedented levels of concurrency. In these parallel systems, synchronization and memory operations are becoming considerably more expensive than before. In this work we study parallel matrix factorization codes and conclude that they need to be re-engineered to avoid u...

Exchange of biochemical substances is essential way in establishing communication between bacterial cells. It is noticeable that all phases of the process are heavily influenced by perturbations of either internal or external parameters. Therefore, instead to develop an accurate quantitative model of substances exchange between bacterial cells, we are interested in formalization of the basic sh...

This paper studied the cluster synchronization of directed complex networks with time delays. It is different from undirected networks, the coupling configuration matrix of directed networks cannot be assumed as symmetric or irreducible. In order to achieve cluster synchronization, this paper uses an adaptive controller on each node and an adaptive feedback strategy on the nodes which in-degree...
