The focus of this paper is on vulnerabilities which exist in Supervisory Control and Data Acquisition (SCADA) systems. Cyber attacks targeting weaknesses in these systems can seriously degrade the survivability of a critical system. Detailed here is a non-intrusive approach for improving the survivability of these systems without interruption of their(More)
Job scheduling is a fundamental issue in achieving a high performance on the Grids. In grid computing several applications require numerous resources for execution which are not often available for them, thus presence of a scheduling system to allocate resources to input jobs is vital. This paper introduces a model and a job scheduling algorithm in grid(More)
We present a preliminary study which explores the potential of aggregation-induced emission (AIE) luminogen as a new fluorescent probe for STED microscopy. Compared with Coumarin 102, which is a commonly used organic fluorophore in STED microscopy, HPS, a typical AIE luminogen, is more resistant to photobleaching. In addition, HPS-doped nanoparticles have(More)
An optimized texture-by-numbers synthesis method and its visual applications .. Abstract Efficient video summarization leads to facilely exploring video content appropriate to the user's intention with low cognitive demand. In this paper, we present a novel approach for summarizing videos in the form of multi-scale structures that exhibit different video(More)
To achieve the promising potentials of tremendous distributed resources, effective and efficient scheduling algorithms are fundamentally important. Unfortunately, scheduling algorithms in traditional parallel and distributed systems, which usually run on homogeneous and dedicated resources, e. g. computer clusters, cannot work well in the new circumstances.(More)
Grid workflow can be defined as an organization of Grid Services into a well-defined flow of operations, and can be thought of as the composition of Grid Services over time on heterogeneous and distributed resources in a well-defined order to accomplish a specific goal. To the time-constrained workflow Scheduling in Grids, we present a scheduling algorithm(More)
To achieve the promising potentials by using tremendous distributed resources, effective and efficient scheduling algorithms are fundamentally important. Scheduling such applications is challenging because target resources are heterogeneous, their load and availability varies dynamically. Previous parallel system was assumed to be organized with homogeneous(More)
A new method of micro-motion parameters estimation based on cyclic autocorrelation function .. Dynamically reconfigurable reaio-over-fiber network with medium access control protocol to provide network access to train Abstract This paper is concerned with the problem of channel estimation for amplify-and-forward (AF) cooperative relay networks with(More)
