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...
As long as extended producer responsibility comes to effect, appliance producers should take the responsibility to recover and reuse the products. Thus, how to disassemble and reuse the discarded appliances scientifically and work out the optimal recovery and disposal strategies are now the key problems the appliance producers confront with. This paper adopts theories related to products regeneration...
Coal-fired boiler operation is confronted with two requirements to reduce its operation cost and to lower its emission. In this paper, a model for boiler efficiency and a model for NOx emission are set up respectively by RBF neural network. In order to obtain more accurate models without trying repeatedly, GA is introduced to optimize the parameter of RBF network. Then Non-Dominated Sorting Genetic...
In this paper we present a novel silhouette-based method to estimate 2D human pose. It takes a pre-defined human skeleton model as the prior information and a video sequence as the data source, and estimates human pose in each frame by the following steps: Firstly, the Gaussian Mixture Background Model (GMM) is adopted to extract silhouette from an image and this silhouette will be the human body...
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...
In China, project finance is still in an exploratory stage. Generally speaking, in practice as well as in literature there is a considerable gap between China and Western developed countries. Therefore, how to push forward and improve project finance in theory as an academic guidance needs urgent explorations. In the light of China's unique features, this paper, with the help of the game theory, has...
