We consider the problem of representing and recognising tools, a subset of objects that have special functionality and action patterns. Our proposed framework is based on the biological evidence of hierarchical representation of tools in the region of the human cortex that generates action semantics. It addresses the shortfalls of traditional learning models of object representation applied on tools...
Computer simulation study of brain neuronal networks is an active academic field. Deep Belief Network (DBN) introduces an effective way of training deep neural networks and the Adaptive Resonance Theory (ART) puts forward a two-layer competitive network emulating human cognitive processes. In our study, we implement a DBN with the mechanism of ART which benefits from DBN's multi-layer structure and...
Recovery rates play an important role in Nth CDS pricing, while, it's difficult to get realistic recovery rates. Assuming that the recovery rates are stochastic and follow different Copulas with corresponding default times. Under this assumption, we develop a simulation Algorithm to price the Nth CDS. According to the result of simulation pricing, the prices of Nth CDS are different under the condition...
Based on multi-layer state space model, the paper proposes a five-layer energy information hierarchical model, and presents a rank normal cloud conversion model to complete the transforming between energy grade and value. To meet the demands of the research, the rank conversion cloud includes two parts, the single energy rank conversion cloud and the integrated energy rank conversion cloud. Finally,...
With international practice and needs of business own development, it's has become more and more common to carry out EPC project in enterprises' contract. Comparing with the traditional patterns of contract, the owners will not involve in the specific process of project in EPC model, so the decision risk of the owners is increased. Through analyzing of EPC contract model, to the ambiguity and uncertainty...
To meet the requirements for being geared to the international standards and to meet the demand for self-development of an enterprise, it becomes more and more common for an enterprise to execute EPC projects. The EPC model compares with the traditional contract model, the risk of general contactor is the biggest undoubtedly. Through the analysis of the EPC model to determine the risk source and loss...
In view of the characteristics of complex system, such as decomposability, complex internal connection, the paper researches multi-layer state space model, and further discusses a same level system mode with graph theory. Finally, it puts forward a multi-layer state space modeling way of complex system based on graph theory, and uses the way to complete a renewable energy statistical analysis model...
With international practice and needs of business own development, it' s has become more and more common to carry out EPC project general contract in enterprises' contract. The EPC model covers basically the entire project construction process and comparing with the traditional contract model, the risk of general contactor is the biggest undoubtedly. To the ambiguity and uncertainty of risk assessment...

This paper presents a general complex switched network (CSN) model that contains switching behaviors in both its nodes and topology configuration. Stabilization of such directed time-varying CSNs with two types of delays is investigated. The two types of delays consist of the system delay at each node and the coupling time-delay between nodes. Based on the Lyapunov stability theory, delay independent...
Steering visualization technology (SVT) is one of the most important research directions of visualization in scientific computation (VISC) recently. Based on the design idea of SVT, the design architecture of steering flight visual simulation system (SFVSS) is proposed. According to the design architecture and function requirement of the system, based on system modeling and simulation (M&S) technology...
