With the tendency of population aging continues in our nation, problems associated with the elderly become major concerns in our society. If daycare centers for seniors can be established to care for the elderly just like daycare facilities for caring pre-school age children, seniors will have a place to enjoy day-time activities and return home to enjoy normal family life. The senior center that...
In this paper, the projective synchronization (characterized by a scaling factorα) in the drive-response dynamical networks whose each node is the parts of four-dimensional hyperchaotic system is studied. Using pinning control for small fraction of nodes in all the drive-response dynamical networks direct the scaling factor onto the desired value. A synchronous criterion ensuring projective synchronization...
On the basis of N-S equations for solving three-dimensional Reynolds problem, k-ε turbulence model and standard wall function for near wall region were adopted. The region was meshed and boundary conditions were given. The software of computational fluid dynamics (CFD) was used to simulate centrifugal fan in the system of lignite quality improved. The parameters of static pressure, moving pressure,...
The purpose of this paper is to investigate and implement a novel approach to learning control for permanent magnet synchronous motor (PMSM) drive system using a hybrid recurrent fuzzy neural network (HRFNN) control. First, the field-oriented mechanism is applied to formulate the dynamic equation of the PMSM servo drive. Then, a HRFNN speed control system that combined supervisor control, RFNN and...

A physically based distributed model with incompact structure is built up by combining the advantages of the conceptual distributed model and the physically based distributed model. Its runoff generation module is based on the improved Green-Ampt infiltration theory, and its runoff concentration module is based on the concentration theory of geomorphological hydrology. In this model, the runoff generation...
