Temperature distribution and its time evolution are fundamental physics of arcs occurring during breaking process in electro-mechanic devices, which largely determine contact erosion. Aimed to the highly fluctuating switching arc, we implemented an optical system based on relatively strength of two individual spectrum emitted by the same excited atoms inside the plasma. Light emitted from arc is firstly...
Keyword search for smallest lowest common ancestors (SLCAs) is an important approach to identify interesting data nodes in XML documents. With the rapid growth of XML data in Internet, how to effectively process massive XML data becomes an interesting topic. As an open-source cloud computing platform developed in recent years, Hadoop is a trend to process large-scale data, which makes possible massive...
Roads in the affected areas are usually damaged during big natural disasters, and it results in blocked road, reduced road capacity, lower vehicle speed and severe restrictions for travelling. Besides, vehicles are donated temporarily by numerous groups and various in their performance. This paper takes the above problems caused by road damage into consideration, and the vehicle route decision are...
The rapid development of international trade simulates the demand for international transportation, and the so-called intermodal transportation has been paid widely attention for the adoption of containers. This paper proposed a mixed integer linear programming model to design the intermodal transportation lines, and the decisions includes (i) the utilization of ports; (ii) the transportation lines;...
Big data processing is one of the hot scientific issues in the current social development. MapReduce is an important foundation for big data processing. In this paper, we propose a semantic++ MapReduce. This study includes four parts. (1) Semantic++ extraction and management for big data. We will do research about the automatically extracting, labeling and management methods for big data's semantic++...
This paper is to explore new improved graded rough set model. Based on logical OR operation of grade approximation operators, this paper proposes logical OR model of grade approximation operators. In the new model, basic structure and properties are obtained, and macroscopic algorithm and structural algorithm are proposed. Finally logical OR model of grade approximation operators, is explained by...

The paper is to explore product operation of grade upper approximation operators. Based on logical product operation, it proposes product model of grade upper approximation operators based on two parameters. Essence, basic structure and properties are obtained in the new model. Macroscopic algorithm and structural algorithm are proposed and analyzed, and it obtains an important conclusion that structural...
Robustness enhancement scheme in Serial RapidIO (SRIO) interconnect is proposed to overcome the performance degradation caused by noise and Electromagnetic Interference (EMI). The main idea of this scheme is the adaptive speed transition and mode conversion. Adaptive speed transition can improve average throughput and reduce delay in high Bit Error Rate (BER) environment. Mode conversion is to conquer...
In this paper, a method for texture retrieval based on scale and rotation invariant directional empirical mode decomposition (SRIDEMD) is presented. Different from other filtering based techniques such as wavelet and Gabor decomposition, EMD uses the nonlinear filtering process called 'sifting' which attains its scalead aptivity and obtained intrinsic mode functions (IMFs) which has approximate orthogonality...
In order to solve the existing problems of modern service operation support system (MOSS) in modern service industry, such as lacking of dynamic modeling capability, this paper brings us a novel dynamic modeling scheme, which improves the flexibility, universalization and portability of business intelligent (BI) service component. Based on the thought of model driven architecture (MDA), this paper...
This paper addresses the control of angular velocity of a rigid body with two actuators. Based on the feedback transformed system, a discontinuous feedback control law is proposed with finite time terminal sliding mode. Numerical simulation is implemented. The results show that the control law can stabilize the system with exponential rate.
In this paper, we study the major modules of on-line handwritten chemical expressions recognition. We propose a novel algorithm that combines two separate methods to segment expressions, one of which is based on structural information and the other on partial recognition. The algorithm improves the traditional algorithm at the stage of recognition, which consists of a substance recognizer and a character...
This paper presents a global optimal technique based on moving least square (MLS) fitting technique and improved differential evolution algorithm (IDEA) for inverse problems on optimizing electromagnetic equipments. In the proposed method, MLS are firstly used to simulate complex objective functions as a response surface model (RSM) in multidimensional space, for transforming an implicit function...
