In order to meet the requirements of hydraulic servo control technology, the structural parameters of the hydraulic flapper-nozzle of the water hydraulic servovalves are studied. By theoretical analysis, the simulation conditions of the hydraulic flapper-nozzle valve are confirmed. Simulation method is used to analyze the diameter of nozzle straight tube and the diameter and length of nozzle hole...
With the advancement of internet, computer network security has brought serious concerns. Intrusion detection is an important topic in network security framework. To address the effectiveness and efficiency problem with traditional intrusion detection models, we present an intrusion detection method based on deep leaning. The deep belief network (DBN) constructed via the stacked Boltzmann machine...
This paper first discusses the narrow and broad sense of the Knowledge Supply Chain (KSC) proposed by Chinese scholars, and based on this, advances the definition of the Enterprise Knowledge Supply Chain (EKSC). Then, the three problems needed to be solved in constructing the EKSC are put forward which include the ignorance of the peripheral branches of the Enterprise Knowledge Supply Chain (PBEKS),...
Fault diagnosis and monitoring is an important part of the intelligent diesel engine technology. The fault simulation of diesel engine is crucial to the research of on-line monitoring and fault diagnosis technology, and it is also an important content of the experimental verification. This paper introduces a real-time simulation platform for diesel engine faults, which is built with SIMULINK, RTW...
Security mediated certiflcateless public key cryptography (SMC-PKC) provides certificateless cryptography with instantaneous revocation. Security mediated certificateless signature (SMCS,) is one of the most important security primitives in SMC-PKC. In this paper, we first formalize the definition and security model of security mediated certificateless signatures, and propose a SMCS scheme which is...
Congestions in many-to-many videoconferencing are usually caused by multiple senders, the congestion information feedback, bottleneck link judge and sending rate adjust are much different from one-to-many multicasting. In this paper, we propose one multicast congestion control scheme based on end-to-end tomography (ET-MCC) for many-to-many videoconferencing. The end-to-end packet loss rates are measured...
