Over the past four decades, various methods have been implemented to measure synchronization of motor-unit firings. In this work, we provide evidence that prior reports of the existence of universal common inputs to all motoneurons and the presence of long-term synchronization are misleading, because they did not use sufficiently rigorous statistical tests to detect synchronization. We develope...

Recent advances in technology have made low cost, low power wireless sensors a reality. Clock synchronization is an important service in any distributed system, including sensor network systems. Applications of clock synchronization in sensor networks include data integration in sensors, sensor reading fusion, TDMA medium access scheduling, and power mode energy saving. However, for a number of...

Multi-core technology is the key technology of mobile cloud computing, with the boom development of cloud technology, the authors focus on the problem of how to make the target code computed by mobile cloud terminal multi-core compiler to use cloud multi-core system construction, to ensure synchronization of data cross-validation compilation, and propose the concept of end mobile cloud entity i...

The Kuramoto model is a classical used for the describing of synchronization in populations oscillatory units. In present paper we study with delay focus on distribution oscillators’ frequencies. We consider series rational distributions which allow us to reduce population dynamics set several differential equations. use bifurcation analysis these equations transition from asynchronous synchron...

Secure communication using synchronization between chaotic systems(chaotic secure communication, for short) is a new concept of secure communication. The great potentials of this kind of “hardware key” secure communication systems had driven the progress of this field rapidly. Since 1992, chaotic secure communication had evolved four generations. In this paper, a detailed history of chaotic sec...

As multiprocessors scale beyond the limits of a few tens of processors, they must look beyond traditional methods of synchronization to minimize serialization and achieve the high degrees of parallelism required to utilize large machines. By allowing synchronization at the level of the smallest unit of memory, ne-grain synchronization achieves these goals. Unfortunately, supporting e cient ne-g...

The goal of current paper is to provide an overview of all synchronization tasks to be performed in orthogonal frequency – division multiplexing (OFDM) based communication system. Symbol timing and frequency synchronization solutions in systems with cyclic prefix (CP) are described. Basic channel estimation and equalization based on pilot tones is described and simulation results presented. Alt...

Orthogonal frequency division multiplexing (OFDM) technique is being applied extensively to high data rate digital transmission as it is a bandwidth efficient modulation scheme. In OFDM system, intersymbol interference (ISI) and intercarrier interference (ICI) occur due to synchronization errors. Fast, simple and robust synchronization algorithms are necessary for OFDM systems. In OFDM downlink...

This study demonstrates the modified projective synchronization in Chen-Lee chaotic system. The variable structure control technology is used to design the synchronization controller with input nonlinearity. Based on Lyapunov stability theory, a nonlinear controller and some generic sufficient conditions can be obtained to guarantee the modified projective synchronization, including synchroniza...

This paper addresses the problem of automatically inferring synchronization for concurrent programs. Given a program and a specification, we infer synchronization that avoids all interleavings violating the specification, but permits as many valid interleavings as possible. We let the user specify an upper bound on the cost of synchronization, which may limit the observability — what observatio...
