In daily work, the university instructors play important constituents of teacher and management troop. counselor carries out political and ideological education as the backbone of the students in the daily work of management and education organizers, directors and perpetrators. How to improve the counselors to achieve reasonable structure, excellent quality, stable professional team with ensuring...
Li Mingxiang et al proposed identity based strong designated verifier signature schemes are analyzed, it is found that the scheme of security vulnerabilities: non designated verifier can verify the validity of the signature, and the scheme does not have the unforgeability. Based on the above shortcomings, proposed the improvement scheme. While retaining the merits of the original scheme overcomes...
This paper took the key parts of a dish-style separator: rotary drum, as the object of study. First of all, Solid Edge software was used to set up 3D solid modeling; secondly, ANSYS software was used to analyze the stress of the rotary drum, and the comparison and analysis of strain and stress on the different speed was done; and finally, the intensity of the rotary drum was evaluated. The results...
In Wireless sensor network, data is oriented toward the center node together, which leads to funnel effect. From the data transfer rate angle, we put forward multi-rate application in wireless sensor network, make use of different abilities of data processing and characteristics between different data transfer rate, consider the distance or hops that node away from central node and the load around...
When flexible forming of sheet metal using plasma arc scanning along a straight line, we find that the forming edge appears warping deformation and the bending angle varies along the scanning path, the phenomenas are defined as edge effects, which will reduce the accuracy of forming of sheet metal seriously. The edge effects and its formation laws that appear in negative bending and positive bending...
Distributed source coding theory has long promised a new method of encoding video that is much lower in complexity than conventional video methods. In the distributed framework, the decoder is usually tasked with modeling the correlation noise and exploiting the statistics. In this paper, we first analyze the suitability of laplacian distribution in correlation noise model (CNM), which is the key...
In this paper, the Sum Product Algorithm (SPA) and the Min-Sum Algorithm (MSA) are used for decoding low-density parity-check convolutional codes (LDPC-CCs). The two algorithms have been implemented and run on three different computing environments. The first environment is a single-threading Central Processing Unit (CPU); the second one is the multi-threading CPU based on OpenMP (Open Multi-Processing);...
Electronic Device Descriptions(EDD) are becoming more and more important for the engineering and commissioning process of Distributed Control System(DCS). Electronic Device Description Language (EDDL) is has been the key to interoperability for millions of devices used throughout most process plants. The paper firstly introduces the background and the development history of the EDD technology. And...
Universities are the training base of specialized persons, College students' innovative ability training is an important goal of professional training. Oriented by students' practical ability and creative ability, the vehicle engineering specialty of HYIT insists in facing enterprises' needs, constructs the “Outstanding Engineers” teaching system to improve the students' creative ability and cultivating...
This paper focuses on the current problems of NS2's application in the computer network teaching, and introduces a drag-and-drop GUI nsBench which makes NS-2 simulation development and analysis faster and easier for students and researchers without losing the flexibility or expressiveness gained by writing a script. It is beneficial for student to directly understand the principles of network protocol...
As some problems exists in C language programming intelligent scoring technology, like its intelligence is poor and its determine is not accurately. A new method based on semantic similarity score is designed. The static combed with dynaic semantic understanding are used in it, so the score are more humane, more close to the results of manual scoring, also the determination accuracy is improved.
As the landmark building of Guangzhou, Guangdong Science Center with its unique architectural glamour attracts the world's attention. Combing with the project background of Guangdong Science Center, this paper described the characteristic of architectural design of Guangdong Science Center form the aspects of design concept, graphic design, profile design and architectural forms. Obviously, the excellent...

FRAME model reveals the definition of mobile learning, describes the relationship between learners and equipment. In the FRAME model, the author brings the mathematical concept of well-posedness educational technology, describes...
The feasibility for safety awareness training on commercial vehicle drivers with the application of automotive driving simulator was analyzed in this study, the virtual reality based safety awareness training methodology was also proposed. The reference and specific contents for training courses design was firstly illustrated. The explanation of main architecture planning and implementation methods...
Transformation of the teaching model entails a fundamental change of teachers' role. This paper interprets the implementation of Computer- and Classroom-Based College English Teaching Model in Hebei University of Science and Technology, and then, based on the theories of mediation proposed by Feuerstein, Williams and Burden, analyses the teacher's role as a mediator. It aims to help College English...
Clothing brand recognition is the integration perception of clothing brand functional attributes and affective properties formed by the consumers according to their own psychological characteristics, namely the overall feeling of the clothing brand. In order to construct the questionnaire of clothing brands, this paper formed the prediction questionnaire by using the method of interview and literature...
In this paper, a SIR epidemic model with distributed time delay was proposed. By using the theory of impulsive delay differential equation, we investigate the dynamics under pulse vaccination. We get the conditions for global attractivity of “infection-free” periodic solution and permanence of the “infection” depend on time delay and pulse vaccination.
In consideration of the characteristics of MES construction of steelmaking, hot rolling and cold rolling, this paper presents constructing MES framework for rapid construction of MES application system. MES framework is realized by multi-layer C/S mode, respectively, client system, interface agent, application server. Client system performs authority control of user operation, component upgrade, etc...
An either simple or stylish lifting device was designed according to the engineering requirement for steel billet moving equipment by rolling mills. And equivalent moment of inertia and equivalent of the torque are worked out, using matlab. Finally, it is a feasible mechanism showed by the computational results and provides a basis for the subsequent structural design and optimal design.
The purpose of this study is to investigate the application of variable frequency primary pump technology. The energy conservation effect and feasibility of several kinds of variable frequency circulation pump control in air conditioning system were analyzed. The results show that the temperature difference controls has the best energy conservation effect. The utilization of the control method in...
