This Paper proposed one novel sensorless induction motor speed control system with self-organizing map and fuzzy control. The self-organizing map could train the neural network according to the simulation or experimental induction running parameters automatically. The trained neural network then is employed to preprocess the induction parameters, and the net output is sent to a fuzzy system to adaptively...
An ignition device of periodicity sequence pulse discharge has been designed to explore a new way for the liquid rocket ignition. In the device, turning of the electrode is derived by electric motor and the sparks distribute in sequence on circumference space. By using of high speed camera system, the study is conducted about the electric ignition mechanism of HAN-Based liquid propellant LP1846 under...
The E-commerce develops greatly in recent years, coincidently, the digitalized Network financial management inaugurates as one of the powerful new accounting or financial management tool. It has greater advantages over the traditional financial management tools. This paper is about how to establish such a network for conglomerate enterprises who seeks global businesses.
The confusing unification of local-area networks and active networks is an extensive question. After years of natural research into the location-identity split, we demonstrate the refinement of courseware, which embodies the natural principles of e-voting technology. Here we argue that the acclaimed introspective algorithm for the study of extreme programming by David Clark et al. runs in W(n) time...
Data recovery on Erasure code could effectively improve the reliability of data storage; however, the algorithm also increased time of data recovery. On the basis of that, this paper presents distributed data recovery based on grid service (DDR-GS), which combines with grid services to improve the efficiency of data recovery. Through extensive experiments on random datasets, it is shown that with...
A modified discontinuous deformation analysis (DDA) algorithm was proposed to study the deformation mechanism of rockbolt nearby the fracture surface and the interaction between the rockbolt and the fracture surface. In the modified method, it is assumed that the rockbolt has no deformation in rock mass and its restriction effect on the fracture surface can only be considered. A normal and tangential...
For the requirements of workflow modeling and characteristics of existing modeling method, the integrated object-oriented colored Petri net (IOCPN) model is made. Its formal definition and functioning rules are given. Modeling concept of integrated and object-oriented, abstract transition and abstract place are introduced into this model. With reflecting dynamic relations among business activities,...
A new distribution network reconfiguration method employing plant growth simulation algorithm as optimal means has been presented. The algorithm handles the objective function and constraints separately, and adopts directional search mechanism. It can avoid falling into local optimal point, which may appear in precious bionics random algorithms due to uncertainness of some parameters and/or without...
Dissolved gas analysis is an effective and important method for power transformer fault diagnosis. In order to improve the diagnostic accuracy of power transformer fault, the paper presents a method of hybrid intelligent algorithm of immune support vector machines. Considering the compactness characteristics of dissolved gas analysis data the achieved samples are pre-selected with the immune clustering...
When the intelligent system takes experimental actions or its state transition, it will form control experiences impersonally. According to this fact, the paper proposes to acquire motion rule and programming rule under unsupervised condition from the experiences in parallel so as to form the control knowledge of this system. In the system study, the system deduces rules from experiences and further...
The definition of ATS interoperability is introduced, and analyzed the influencing factor for interoperability. The key element of ATS and the interoperability based on ATML standard to implement every layer of ATS are studied. According to an illustration to descript UUT and test adapter interface, the static models about them are modeled, which is based UML. At last the ATS architecture with interoperability...
Inspects the domestic and foreign each kind of information security event to discover that behind information security event representation, those who play the decision role is the human, the human is in the information security the most active factor, human's behavior and the information security is closely related, human's unsafe behavior causes accident's primary cause. The paper has studied the...
This research work has two parts. The first part is to optimize the operational flexibility of a manufacturing setup and part two is to develop a manufacturing execution system (MES) for a manufacturing setup. Low Volume-High Variety manufacturing environment offers a great challenge for the manufacturer because of the customized orders. Typical manufacturing environment consists of Job Shop, batch...
An unequal error protection scheme is proposed for robust transmission of MELP compressed speech. Plotkin type constructed LDPC codes provide different protection to different part of the codeword. In our scheme, we use this code to encode MELP bit stream in accordance with the sensitivity of the bits in a frame to errors, giving more protection to the bits affecting the speech quality more. Simulation...
In this paper, we proposes a cognitive cross-layer architecture for the cognitive ad hoc networks, where each node in the networks can sense and learn from wireless environment, network environment and user's requirements, and then it will respond the changes of environment by adapting system parameters and network services based on the learned results. In this way, it can provide the end-to-end goals...
In this paper, because of the core for game is usually empty , based on the core of the stochastic cooperative game1 and the core of the n-person repeated stochastic cooperative game5, we define the core of the stochastic cooperative game and the core of the -person repeated stochastic cooperative game. Thus, we recuperate the defect in theory that the core is empty usual. And we introduce some characters...
The propagation and switching of short pulses in an active two-core fiber nonlinear directional coupler have been investigated theoretically by using the numerical simulation method. The analysis highlight the effects of the second order coupling coefficient dispersion, the linear gain coefficient and the finite gain bandwidth on the propagation and switching of short pulses. We demonstrate that with...
By use of the coupled equations of pump, signal and idler field, this paper have derived the gain expression of fiber optical parametric amplifier with high-order dispersion and high nonlinear optics. It is indicated that the optical parametric amplifierpsilas gain is dependent of pump wavelength near zero dispersion wavelength. Gain and bandwidth are better when pump wavelength is close to zero dispersion...
For a V/F controlled induction motor drive system, the instability problem of sustained oscillations has often been experienced in light load state.
