As an important part of system safety, risk assessment is an evaluation process for identified hazards. The corresponding risks should be evaluated to support decision-making. The risk, including the severity and probability of the potential accident, should be evaluated using an integrated index to facilitate risk ranking. In this study, the risk assessment is executed though the analytic hierarchy...
Lots of scholars depend on the Internet for rapid access to the other scholar's research information and build cooperative relationship. But current systems for finding another scholar who share the same research field or interests do not adequately satisfy the need of scholars; moreover the process of seeking is time-consuming and difficult. In this paper, we use the data from scholar's profile in...
High performance of the science and technology innovation team with clear and valuable target, the highly effective leadership, the value of cooperation concept, and team oriented incentive system. But the team cohesion and incentive mechanism construction is the difficulty of science and technology innovation team management. Psychological empowerment is a kind of internal incentive, through the...
In this paper, a new method to solve the hybrid genetic algorithm based on dynamic coding by bargain model in inserting order is proposed. A new coding method for the inserting order is presented also. Corresponding crossover and mutation operators are given. These operators can easily keep the feasibility of solution. They can also satisfy the stochastic demand of genetic algorithm. Finally, an example...
The extractive technique of allicin was investigated in this paper. The optimum extractive condition of allicin was determined through orthogonal design and response surface analysis as follows: the enzymatic hydrolysis time was 32.4min; temperature was 30; pH was 6.0; ratio of material to ethanol was 1:6.4; extracting time was 60min; extracting temperature 27.4; 95% ethanol. Under such condition,...
Research on Changing characteristics of carbon emissions and their driving factors in provincial areas are significant for carbon emission control and reduction policies' formulation. In this paper, the changing feature of total carbon emissions, carbon emissions per capita, carbon emissions of three types of primary energy, and the change of emission structure and emission efficiency of Jiangsu province...
To obtain the bearing characteristics of bored piles, the osterberg method test on four single piles in compression and the axial stress test along the shaft based on strain gauges embedded in piles were conducted. Based on the test results, bearing capacity, side friction, tip resistance and load bearing properties of the piles were analyzed. The results indicated that the friction values of investigation...
The damage of waterproof is a main reason that causes the bridge pavement diseases. Controlling the quality of cementing material is an effective measure to improve the endurance of bridge pavement. 'Two asphalt one aggregate' is put forward to solve the problem of 'white aggregate' appeared on the shearing destruction interface of synchronous crushed stone, The asphalt optimum dosage of 'two asphalt...
In order to make detailed analysis on the mechanical performance and load carrying capacity of cast-in-place bored pile with post grouting technique for highway bridges and study influence factors, FEM method has become one of the most essential assistant way. Based on two groups of trial pile in the same geological region of WEIHE bridge, which located at new airport construction project of Shaanxi...
In order to evaluate the curriculum designing and analysis the teaching effect in food engineering speciality, Principal component analysis (PCA) were used to evaluate the curriculum designing and hierarchical cluster analysis (HCA) were used to analysis the teaching effect by means of the grade of 20 students of food engineering speciality which have graduated in 2007.The PCA shows that every curriculum...
