Abstract: For many risk events in civil engineering construction have the property of “the connotation is explicit, the extension is vague”, the influencing factors of civil engineering construction safety accident are measured with the membership degree in fuzzy mathematics. The weight of indexes of various influencing factors is calculated with the method of analytic hierarchy process, thus a fuzzy comprehensive evaluation model for civil engineering safety accident is given, which is a new qualitative and quantitative solution method and makes it become possible for the early warning of civil engineering construction safety accident. In the end, it is demonstrated with an actual example for the availability of the model in the early warning.

Abstract: The course of Electronics in Electrical Engineering is a basic course for marine engineering majors. In the teaching process, on the basis of Oceangoing Seafarers Competency Test program, the activeness of students is aroused and the efficiency is increased through adjusting the relevant contents, highlighting the key points, and combining theory with practice. In addition, in reference to the comprehensive and the abstract contents, some good teaching patterns are put forward to reform the traditional pattern.

Abstract: Incentive vibrating wire sensor monitoring of coal mine construction safety production targets for the specific environment of the mine buildings, according to the release of the coal and gas will produce the phenomenon of electromagnetic radiation, frequency measurement system based on the TMS320C5402 DSP coal mine construction safety the system has a large amount of collected information, excitation, and storage convenience, it can improve coal mine safety in construction reliability.

Abstract: Multi-storey housing is one of many living space types which has been provided for low-income society in Indonesia. Occupants in multi-storey housing do adjustment process to increase housing unit quality and their dwelling space. The objectives of this study are to explore and to understand how the occupants do adjustment and improving housing unit quality with self-help approach. This study is needed to get the success providing of vertical housing for low-income society in urban areas of Indonesia. The method of this study use descriptive approach with field research at multi-storey housing in Jakarta. Result of this study gives knowledge about adjustment process in multi-storey housing with self-help approach.

Abstract: This paper discusses the establishment and improvement of the performance evaluation and supervision system of public investment projects in China, aiming at promoting the standardization, scientific and rationality of China’s public investment. We constructed a benign long-term mechanism which is deterrent to corrupt behavior in the field of public investment and also promotes economic growth, in order to improve the operational efficiency of public investment projects in China.

Abstract: This paper analyzes several problems in the current construction project management. Factors affecting construction qualities have been brought up, as well as the characteristics of construction quality information. In addition, the strategies of applying computer technology into solving the problems of construction quality management have been proposed, such providing a theoretical guidance for the implementation of information technology in construction enterprises.

Abstract: Based on the prediction principle of the surplus service life of building’s durability and through prediction of atmospheric climate change, the data demonstrate the atmospheric environment effect will shorten the life of the building.

Abstract: This paper discusses about the quality management of security housing. The paper analyzes quality problems which happened in the process of security housing construction, and analyzes the factors of impaction about the quality of security housing. There are some uncoordinated points and problems between the public goods characteristics of security housing and the policies about these characteristics and security housing construction quality. In the end it proposes specific countermeasures to solve the quality problems. Construction security housing is a systemic engineering and it needs multi-joint efforts and coordinated function of all participants.

Abstract: Improve the efficiency and scientific of government supervision working in construction quality is an essential for enhancing its effectiveness, government supervision in construction quality standardization is effective measures for improving supervision. The paper analysis the purpose carries out government supervision in construction quality standardization from two perspectives, including the chief part of supervision and the operation of supervision; and dissects a significance of building government supervision in construction quality standardization system from six aspects, including change the way of supervision, supervision development and revolution, improve supervision efficiency, mend supervision means, distinguish nature of supervision responsibility and the code of conduct of supervision. Based on internal demand and operating characteristics of government supervision in construction quality, constructing two systems which include supervision process and decision standardization; and decomposes the structure and interactive relationship between the systems. Realize government supervision effectively in construction quality through standardization.

Abstract: Power systems need an auxiliary system that must take corrective actions on the occurrence of a fault. One of the most important equipments employed in the protection of power systems are protective relays. These are one of the most flexible, economic and well-known devices that provide reliable, fast and inexpensive protection. In this paper, we introduce a new method to protect the power system by digital relaying.
