Eduroam, the world-wide roaming system for research and educational institutions, has several shortcomings such as unstable and slow user authentication and weakness against network/proxy failures. We propose a disruption-tolerant authentication architecture based on the combination of certificate-based authentication and the centralized authentication system called Delegate Authentication System...
The paper describes the current research situation of automotive ride comfort from two aspects of experimental and simulation. The dynamics model with five degrees of freedom of a bus is established, meanwhile the kinetic equations is also derived according to D'Alembert principle. A road simulation model of class B is also established on the basis of white noise method. Combined with vehicle model...
Network reliability is very important in our modern society. The primary network reliability research focuses on connectivity reliability. Recently, network performance is receiving more and more attention, and network performance reliability concept is promoted, such as travel time reliability. But it is very hard to evaluate it. One of the reasons is high computational complexity. Although this...
The management of spare inventory with lateral supply is an effective approach to improve support effectiveness and reduce the support costs. Focusing on the problem, a spare inventory model with lateral supply was proposed considering the current facilities supply mode. Considering relative important time and cost indexes, the model is further extended with lateral supply cost. Finally, an example...
This paper presents a signal processing engine aiming to provide the brush function for electronic papers. The engine contains four stages: (a) screening the detected pixel coordinates, (b) interpolating pixels, (c) image halftoning for generating more visual gray levels, and (d) driving the pixels to the target states. The experimental results show that the engine can complete the pixel interpolation...
This paper introduces difference mutation idea for diversified search to elitist search-based immune optimization algorithm for function optimization. The idea of difference mutation is merged into the process of clonal selection and hupermutation algorithm, so that the new solutions have the tendency to get close to the global optimal solution. The introduction of differential algorithm idea greatly...
Along with the unceasing expansion of colleges' library network scale, the problems of network security are obviously increased. This thesis describes the advantages of VLAN and its practical significance on library local area network, and analyses the library network application and structure in colleges and universities. Based on the design of the library network in Xinyang Agricultural College,...
School education belongs to the category of service industry. Students are the significant sources of new ideas about teaching innovation. The paper has put forward three dimensions of students participating in teaching activities, analyzed the influence mechanism of student participation on teaching innovation, and disclosed the relationship between student participation and teaching innovation from...
Currently there are many problems in the engineering education in China, mostly due to that the collaborations between universities and enterprises are so insufficient that the students are always lack of necessary engineering practice. Consequently, reformation of engineering education is needed in order to address this issue, in the background of which the project discussed in this paper is carried...
