The RBF network-based SST models are built using the random SST samples from 0.25° grid resolution OISST product and 0.05° grid resolution OSTIA product, respectively. And in order to test the effects from the SST samples and the hidden knots of the RBF networks, the RMSEs are calculated with different number of hidden knots from 1 to 100 and various percentage of SST samples at 5%, 10%, 15%, 20%...
A forward Monte Carlo 3-D (FMC3D) model is developed for simulating light fields in a volume of water where the boundary conditions for radiance values can be expressed by mathematical formulas, which cannot be done using the radiative transfer models currently available such as HydroLight. Water is assumed parallel homogenous for these models, which are incapable of investigating the sidewall reflectance...
According to the concept and characteristics of virtual assembly feature, reconstruction method of virtual assembly feature model is proposed. Using the secondary development tools provided by ProEngineer, namely, ToolKit, getting assembly information is implemented. Based on analysis about three kinds mapping methods between the geometric elements and triangulated patches, an complete information...
Engine start process is especially very vital to hybrid electric vehicles, because vehicles fuel consumptions can be arrived through engine frequent start and stop events. On the other hand, if the process can't be controlled smoothly and fast, it would cause large vibration of vehicles which will largely deteriorate a driver's ride comfort. As a result of it, a control strategy for engine start has...
PSHEV(parallel-serial hybrid electrical vehicle) has the advantages of serial and parallel HEV in that it includes the E-CVT(Electro-continuous variable transmission) structure. Whether E-CVT control strategy is good or not has a direct effect on the whole car's fuel consumption and gas emission. Conventional PID algorithm is a kind of control method based on the error theory without consideration...
