This paper describes an icing software toolkit applied to predict the ice accretion layer by layer on the surface of airfoil. Based on modular programming method, this code consists of five separate modules with functions respectively as geometry redefinition, grid generation, airflow calculation, calculation of droplet impingement, and analysis of ice-layer growth. Once the multi-step algorithm is...
Presently, the number, types, and distribution of resources in a resource allocation system (RAS), may change frequently and dynamically due to fluctuant customer demands. Such changes in a resource allocation (RA) specification mean different production or service behaviors yielded by the providers. This new situation gives rise to a challenging problem, namely, how to switch smoothly the provider...
Solar radiation (Rs), a critical variable in eco-environmental models, is not measured at many meteorological stations. Prediction of Rs has drawn increasing attention in the recent years. The aim of the present research was to conduct a comparative study of estimating Rs from measured maximum and minimum temperature and dew point temperature at daily, five-day, ten-day, monthly time scales. Coefficient...
The product shape innovation design has possessed a very important ability to develop more pleasurable products, in which Shape Descriptor is one of key technologies. A new describing method of product's shape based on complex coordinates and Fourier operator is presented, which includes the following five steps. The first is to pre-process, which can obtain the form contour information from product...
Pneumatic driven system has been widely used in industrial automation mainly for relatively simply tasks with open-loop control. With regard to closed-loop controlled axes in robotics, servo-electric driven systems have been dominant up to now. This paper introduces a new closed-loop control servo-pneumatic system that can do continuous positioning. The mathematical model of the servo-pneumatic system...
