It is well known that cascading failure is one of the key factors which lead to blackout events around the world. How to simulate cascading failure reasonably is one of the important issues to be solved by electrical engineers. An ad-hoc cascading failure model based on probabilistic line outage and failure correlation is proposed in this paper. The proposed model involves AC power flow computation...
Realistic humanoid character movement is very important for the application of in the computer games and animations. However, 3D character pose has a very high dimensional data together with joint rotation, body position and orientation. This paper demonstrates a technique in deforming various motion styles from normal to strong and to exaggeration mode by deforming specific pose from 3D character...
Movement pattern recognition is the basis for flexible control of lower-limb rehabilitation aids. To improve the effect of lower-limb movement pattern recognition, an electromyographic recognition method to identify movement patterns without movement information was proposed. Firstly, the initial moment of feature extraction was detected by the integral of absolute value of surface electromyography...
In recent years, blackout accidents taking place across different countries really shock the world, reminding electrical engineers that the power grid is still far from robust and strong enough against complex operating environment and uncertain load conditions. During the process of cascading failure, the event chains grow longer with the spreading of failures which are mostly caused by over-limit...
In order to timely synchronize the nodes in unstable network environment and reduce the space overhead of the operation log, we mix the operation transfer-based and state transfer-based synchronous models. In this paper, for file system synchronization, we design an improved file system synchronous algorithm -- the combination of state transform algorithm and operation merge algorithm. The experimental...
In order to improve the survivability power of embedded real-time systems (ERTS), according to the character of it, strengthened design method was used to realize survivability design. Then through chose analysis of embedded mobile video-on-demand system, the intrusion tolerant technology was introduced in whole survivability design.
This research came from a school-enterprise cooperation program, which intends to improve the quality of software testing process in SAP IDDC team. In data collection stage, it was found that one of six measurements, number of test case executions, had 77% data missing in monotone due to the newly adopted test case tracking tool. Three common imputation approaches, Multiple Imputation (MI), Expectation...
Human capital is an important factor affecting a country's economic growth while education is the main channel to form human capital. Based on China's provincial panel data from 1987 to 2008, this paper investigates into the relation between economic growth and education acquisition. The empirical study denotes that human-capital-based product function is convex, which denies the traditional hypothesis...
In the process of searching for the optimal solution, particle swarm optimization algorithm falls into the local optimal easily. It affects the convergence precision of the algorithm. For the shortcoming of the algorithm, a new method, which the particles are fixed distribution to the search space, is proposed. It makes the distance among the particles, improves the searching area, increases the searching...
MicroRNA (miRNA), which is short non-coding RNA, plays important roles in almost all biological processes examined. Several classifiers have been applied to predict humans, mice and rats precursor miRNAs (pre-miRNAs), but no classifier is applied to classify porcine pre-miRNAs only based on the porcine pre-miRNAs because of little known miRNA component in the porcine genome. Here, we developed a novel...
In modern enterprise, project team has become a much more effective form for its flexible, problem-oriented and task-oriented. Knowledge sharing among teams plays a significant role in knowledge management of enterprise. Based on principal-agent theory, this paper explores the benefit game between enterprise and project team under information asymmetry condition, introduces both knowledge value and...
We described a combined multiple clustering approach to automatically identify chronic lymphocytic leukemia neoplastic population by flow cytometry immunophenotyping. Flow cytometry data from various specimens were preprocessed by data cross-linking and subset selection before undergoing subspace and consensus clustering. This approach was implemented as a Server-side application, with results comparable...
Based on the analytic expressions given by T. Hasegawa, et al.. (J.Acoust. Soc. Am. 79(4) 927-931 1986) an integral for calculation of the radiation force on a plane absorbing target in spherically focused field is derived. For focused fields a general relation between acoustic power P and normal radiation force Fn, P=GFn is obtained from the integral. Numerical computation of the integral is carried...
Based on three-layer structural model (ERP/MES/PCS) of process industrial integrated automation, it provides a brief introduction to the manufacturing execution system. The conception and main content of UML is introduced. Combined with quality management system in cement enterprises and modeling tool Visio, modeling process and typical UML views are given.
Cement production process and its administration feature are exposed and analyzed. On the basis of that, it brings forward cement enterprise manufacturing execution system (MES) architecture that centers on real-time database. The design approach of RTDB, design practice and method of cement enterprise MES information integration are significantly researched. Finally a successful realization case...
The present state of cement industry information system construction and the cement production process feature are briefly exposited and analyzed. On the basis of absorbing advanced thought and technologies such as Industrial IT, ERP and MES, it comes up with cement enterprise information system architecture, being more easier to be put into effect, based on three-layer structure (ERP/MES/PCS) and...
In this paper, we propose a method of constructing a virtual coordinate system (ABVCap) in wireless sensor networks where location information is not available. A routing protocol based on ABVCap virtual coordinates is also introduced. Our routing protocol guarantees packet delivery and does not require computing and storing of the global topological features. Using simulations, we evaluate the performance...
