China Open University system, as an exclusive university organization that is specialized in distance open education in China, adopts the network teaching way, and whose teaching network covered the whole country, so the system's teaching quality is increasingly attracting attention, and the teaching reform measures used to improve the teaching quality also have been taken. Apparently, utilizing data...
This paper proposed an automatic detection and automatic configuration method of 1553B RT device based on SoC chip. This method made SoC as information dealing unit of each terminal on 1553 bus. Electronic data form was added on the RT device, and a multi-task management procedure was run on the BC device. When a RT device was plugged in or pulled out the 1553 bus, the operation was detected and the...
This paper proposes a Quality of Experience (QoE) test methodology for adaptive streaming service. We analyze the factors influencing the QoE of adaptive streaming, and evaluate the QoE of the end-to-end service. Our research gives the evidence that adaptive streaming improves end-users' subjective perception greatly compared with fixed-rate streaming in terms of QoE. Two groups of experiments are...
According to the characters of the logistics center location project evaluation, considering that the incomplete and uncertain intraval attribute information of the logistics center location evaluation can be reflected effectively by the traditional extension decision-making model, Extension decision-making model with grey interval number is proposed based on the grey system theory. At the course...
The products of higher education provided to the customers by colleges and universities are service. Service attribute is the basic characteristic of higher education. Whether customer is satisfied is very important to the future of college. The model of service customer satisfaction in higher education is established to explore the relationship of service quality, image of colleges and universities,...
Segregation in the Hot-Mixed Asphalt (HMA) causes inferior homogeneity of pavement structure which is a key contributor to the early pavement damage. This paper, by statistic principles, analyzes the contributive factors to the segregation, indicates the major factors and guides the controls in actual project, thus to reduce the unevenness of the pavement and improve the quality and durability of...
The application of video resources has become extensive, and the demand to the video retrieval is growing intensely. How to access the video clips expected quickly and accurately from the massive video database has become the key issue in the development of the video information retrieval. The existing retrieval process based on keywords is no longer meeting the needs of users. Thus, video retrieval...
To make accurate appraisal of the competitiveness of construction enterprises, DEA model is adopted and extended. The integrated competitiveness and state of returns to scale were analyzed. The inefficient DMUs were diagnosed and optimized by changing the index and using projection analysis and the efficient DMUs were discriminated by super efficiency and sensitivity analysis. Then, forecast about...
In recent years, multi-erasure correcting coding systems have become more pervasive. RAID6 is an important 2-erasure correcting code specification. But there is no consensus on the best concrete RAID6 coding scheme. Plank developed a brand new class of RAID6 codes called the Liberation codes that achieves good encoding, updating and decoding performance. In this paper, we present a chained decoding...
With the development of e-learning, it is important to make e-learning evaluation scientifically and objectively. And now there are so few methods for e-learning evaluation. This paper proposes a method based on fuzzy comprehensive evaluation system of e-learning, and design a evaluation system and solution in order to provide more valuable reference for education decision makers.
