We propose an approach for the synchronization of video streams using correntropy. Essentially, the time offset is calculated on the basis of the instantaneous transfer rates of the video streams that are extracted in the form of a univariate signal known as variable bit-rate (VBR). The state-of-the-art approach uses a window segmentation strategy that is based on consensual zero-mean normalize...

MOTIVATION Although there are significant advances on elucidating the collective behaviors on biological organisms in recent years, the essential mechanisms by which the collective rhythms arise remain to be fully understood, and further how to synchronize multicellular networks by artificial control strategy has not yet been well explored. RESULTS A control strategy is developed to synchroni...

For a given multi-agent system where the local interaction rule of the existing agents can not be re-designed, one way to intervene the collective behavior of the system is to add one or a few special agents into the group which are still treated as normal agents by the existing ones. We study how to lead a Vicsek-like flocking model to reach synchronization by adding special agents. A popular ...

Exokernel is a minimal operating system kernel that safely multiplexes hardware resources, while leaving all system abstractions to applications. An exokernel exhibits better performance and offers more functionality because applications can provide optimized system abstractions, at the user-level, based on their needs. Current design of the exokernel system, however, does not support multiproc...

Some concerns in the design of operating systems are hard to modularize in the implementation and thus difficult to maintain. One of these “crosscutting concerns” is the interrupt synchronization strategy. Changing that strategy is typically expensive and risky. Aspect-oriented programming (AOP) is a promising approach to overcome these problems, but most aspect-oriented programming languages a...

Recently, the studies about parallel image processing have been performed extensively. Many systems adopt the data parallel processing for their parallelizing strategies. In the data parallel processing strategy, input image data is divided into some fragments, and each fragment is processed on each processing element (PE). However, in this data parallel strategy, the synchronization among proc...

Audio mixing greatly degrades the watermarking security. Consequently, it is of importance to introduce mixing-attack-proof audio watermarking algorithms. This article investigates audio mixing attack. A randomized embedding spread spectrum audio watermarking algorithm is accordingly proposed to improve the watermark immunity to mixing attacks. First, balanced modulation is introduced to get ri...

In this paper we present a novel synchronization protocol to synchronize a network of controlled discrete-time double integrators which are non-identical, with unknown model parameters and subject to additive measurement and process noise. This framework is motivated by the typical problem of synchronizing a network of clocks whose speeds are non-identical and are subject to variations. This sy...

This paper investigates a distributed, coordinated motion control network based on multiple direct-drive, linear switched reluctance machines (LSRMs). A hierarchical, two-level synchronization control strategy is proposed for the four LSRMs based motion control network. The high-level, reference signals agreement algorithm is first employed to correct the asynchronous behaviors of the position ...
