Pulse vaccination is an important strategy which can eliminate epidemic. Nowadays studied focus on the latent and immunity period of epidemic, which can reflected by the epidemic model with the time-delay system. Using this principle of pulsed optimization to analyse SEIR epidemic model with latent period. It can achieve the target of controlling infectious disease via optimization the number and...
Small size motorized spindle is widely applied in microscale machine tools (mMTs) in precise manufacturing. Spindle characteristics should be analyzed in machine tool design and optimization. Spindle -toolholder system is the weakest part in the whole machine tool. Precise 3D model of spindle is established to calculate deformation at the top of spindle using ANSYS. Natural frequency is also calculated...
The thermal ceramics industrial wastewater, discharged in Morgan, Kailong (Jingmen) Thermal Ceramics Co., Ltd, is quite difficult to handle with conventional biochemical methods due to complex ingredients and poor biodegradability. Integrated innovative process optimization has been applied to achieve ideal treatment performance. The results show that the optimized project has brought about remarkable...
A new UAV path planning method based on ant colony optimization (ACO) is presented. The target position is considered as the food source which the ants are going to find. The enemy defense region is considered as the searching area of the ants and is divided into equally spaced grids. The ants move to the destination node through several nodes on the grid region. The visibility function of ACO algorithm...
With the rapidly changing environment, more and more products are having the characteristics of the perishable product. Simultaneously, our companies face the problem of product return more often than before. Based on the idea of product age, using discrete event simulation technique, the model about the perishable product inventory system with resalable product return ,under the assumption that part...
