Life parameter is important for product. It is very important for an engineer to predict system lifetime. Reasonable approaches of system life prediction can cause exact prediction of system life. One approach of system life prediction based on key apparatus is presented to solve the questions of absence of system life data and experiments of system life. By confirming the key apparatus of system...
The volumetric percents of CO, HC, NOX, CO2 and O2 from the exhaust of an EFI gasoLine engine were measured and analyzed under the working conditions of its cold-start, cold-acceleration-deceleration, warm-deceleration and warm-acceleration. The results show that: A large amount of HC and CO is emitted from the engine under cold-start condition. During this period, the catalytic converter doesn't...
In order to research the handling and stability of the HPS vehicle, Matlab/Simulink is applied to build the HPS model and the three degree-of-freedom vehicle model. From the test, the simulation model is testified correct. Then analyze the influence of some parameters on vehicle's handling and stability through the simulation. The study provide basis for the steering system's design and the improvement...
Towards gaining the performance improvement benefited from threaded MPI while supporting MPI standard well, in this paper, we propose a thread-based MPI program accelerator (MPIActor). MPIActor is a transparent middleware to assist general MPI libraries. People can choose to adopt or abandon MPIActor freely in compiling time for any MPI program (Currently only support C code). With the join of MPIActor,...
