In this paper, a service architecture based on overlay network was presented. The architecture was designed to build a novel distributed video surveillance system, called as Etouch. In the model, the system is divided into three layers: underlying network layer (UNL), overlay service network layer (OSNL) and application layer (AL). OSNL is composed of many intelligent overlay nodes mapped by un...

in this paper, a bidirectional associative memory (bam) neural network, which consists of two neurons in the x-layer and three neurons in the y-layer, with two time delays will be studied. we conclude that under some assumptions, hopf bifurcation occurs when the sum of two delays passes through a critical value. a numerical example is presented to support our theoretical results.

Free swelling index (FSI) is an important parameter for cokeability and combustion of coals. In this research, the effects of chemical properties of coals on the coal free swelling index were studied by artificial neural network methods. The artificial neural networks (ANNs) method was used for 200 datasets to estimate the free swelling index value. In this investigation, ten input parameters ...

Today, e-commerce has occupied a large volume of economic exchanges. It is known as one of the most effective business practices. Predicted trust which means trusting an anonymous user is important in online communities. In this paper, the trust was predicted by combining two methods of multiplex network and community detection. In modeling the network in terms of a multiplex network, the relat...

tthe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. this paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. as a novelty, the proposed controller employs a simple gaussian radial-basis-function network as an uncertainty estimator. the proposed netw...

Network security situation awareness is vital important for network security supervision. In order to obtain the network security situation effectively, a multidimensional assessment method is proposed in this paper. The method is composed of three dimensions at different levels, namely vulnerability, threat and basic operation, with quantitative calculation method for each index. In the servic...

The OMEGA architecture provides end-to-end quality of service (QoS) guarantees for distributed applications. QoS parameters are translated between application and network requirements by the QoS Broker, thus integrating media and network QoS management into a single entity. Admission control uses a schedulability test derived from application requirements. A novel task priority and precedence b...

Recently, the emergent dynamics in multiplex networks, composed of layers of multiple networks, has been discussed extensively in network sciences. However, little is still known about whether and how the evolution of strategy for selecting which layer to participate in can contribute to the emergence of cooperative behaviors in multiplex network of social interactions. For this purpose, we con...
