At the same time, we should also see that the administration according to law is not perfect, and its shortcomings exist in different degree and need to be further improved. Based on the analysis of the status quo of grass-roots administrative law enforcement in China, this paper tries to put forward corresponding countermeasures, so as to promote the work of law-based administration for the corresponding study.展开更多

In a typical chemical process, there are hundreds of process variables. Feature selection is a key to the efficiency and effectiveness of FDD. Even though artificial immune system has advantages in adaptation and independency on a large number of fault samples, antibody library construction used to be based on experience. It is not only time consuming, but also lack of scientific foundation in fault feature selection, which may deteriorate the FDD performance of the AIS. In this paper, a fault antibody feature selection optimization(FAFSO) algorithm is proposed based on genetic algorithm to optimize the fault antibody features and the antibody libraries' thresholds simultaneously. The performance of the proposed FAFSO algorithms is illustrated through the Tennessee Eastman benchmark problem.展开更多

This study synthesized 9 influential categories including 91 factors related to quality management of public works in Taiwan using a sequential analysis procedure. According to the Borda-values of influencing factors obtained from a first stage questionnaire, the number of primary factors selected by the re-sponsible entities and the design-supervisory entities were 44 and 45 respectively. A Fuzzy Analytic Hierarchy Process (FAHP) was used to prioritize and rank these factors. The top five factors ranked by the responsible entities were (1) introduction of the earned value analysis, (2) working efficiency, (3) environmental laws and regulations, (4) price-index fluctuation, and (5) on-site safety management. The top five factors ranked by the design-supervisory entities were (1) man power, (2) laws and regulations, (3) price-index fluctuation, (4) traffic conditions, and (5) faulty design.展开更多

Mass concrete, due to its large size and volume, presents a considerable temperature rise caused by cement grain hydration. This temperature rise can be sufficient to cause concrete crack and/or cracking, which may lead to serious problems. In this paper, we sought to study heat generation and temperature field in mass concrete through ANSYS software, which uses finite element method to analyze the problem. This program allows temperatures to be checked for different concrete ages. With that, it is possible to evaluate the temperatures obtained and the factors influencing the results in a short period of time at a low cost. With the help of the software, it is possible to check the temperatures for different concrete properties by analyzing them on different concreting days. Therefore, it was possible to establish that the properties of the concrete directly influence the temperature evolution phenomenon.展开更多

This approach is expected to foster the students＇ design skills in design studios. The approach is an educational tool for tutors that could guide the students and increase their creativity in their design. It considers the concepts and the practice of digital architectural design that influence architectural education. The approach is a catalyst for creativity, experimentation, critical thinking and the sustained growth of creative communities. The core of design studio is the notions, methods and skills of digital architectural design. The instruments used for this research was an investigation that made for the work of the fourth year students designs at the architectural department at University of Jordan, by testing design process and product of students＇ work： first using manual skills, and then using computer-aided programs. The results revealed that the computer-based design approach was able to foster students＇ design skills as well as to develop their creativity in design. Ninety-one percent of 44 students were found improved in design process using computer-based approach that depends on computer programs. This was done in design studio by improving students＇ way of thinking, developing their abilities to direct their own learning and pushing them for new definitions in developing their future work.展开更多

In addition, the Article 8 of the Ordinance of City Planning Law resulted in not so effective against tsunami in March 2011. Control mechanisms of building construction should be integrated into socio-economic, institutional, technical and other policy tools. In order to mitigate earthquake risk, all stages of building construction, from location, planning and construction to maintenance are important. Awareness creation is instrumental for building culture of safety and demands for intervention in disaster mitigation. The demands ultimately help in creating conducive environment for policy intervention, in realizing institutional mechanism of building code enforcement and land use control for the municipal authorities and in creating demand for competent professionals.展开更多

From this point, it is important to encourage the development of the basic techniques of control systems, electronics and communication in order to produce knowledge in the mechatronic field and so apply them to industry. Considering the relevance of this subject, the students of Federal University of Para-Campus Tucumi through the Research Group of Electrical and Mechanical Systems apply their knowledge in multidisciplinary engineering fields in order to generate knowledge from creative techniques using low cost materials, together with the encouragement of social and environmental responsibility which is very important nowadays. At the same time, targeting the needs of the labor market, this work aims to foster in students the skills and requirements through team projects and innovative methods. Therefore, this paper presents a mechanical manipulator, where their operating characteristics are based on industrial robots in the literature, powered by DC （direct current） motors and fully developed from reusable materials. By adding a developed control from the Arduino, prototyping platform with an electronic strategic offers through the internet the long-distance control convenience.展开更多
