To solve the inaccurate injection quantity problem in multiple injections of high pressure common rail injection system, in this paper, a simulation model of the system is developed in AMESim environment, and the injection quantity fluctuation characteristics with respect to the dwell time between consecutive injections and pilot injection quantity are investigated. The results show that injection...
With reference to the disproportionation of trichlorosilane to silane, a three-stage consecutive reversible reaction with a rather unfavorable reaction kinetics, in-depth comparison in steady-state performance is performed between the column with a single reactive section and those with multiple reactive sections, adopting the equal number of trays and the equal amount of catalyst. The reactive distillation...
With the development of new energy technology, more and more plug-in electric vehicles (PEVs) have appeared in our lives. In vehicle to grid (V2G) information exchange, the method that PEVs use to access the grid for information and vehicular data collection is the key factor that affects the reliability and real-time nature of V2G communication. Vehicular power line communication (VPLC) reuses vehicular...
The normal and reliable operation of the battery system in the electric vehicle plays a critical role to ensure safe and comfortable driving for users. In practice, a very common problem of battery system is charge imbalance. To solve this problem, battery equalization has been introduced as a part of the battery management system. In order to design a battery equalization system and improve its performance,...
A novel anti-ESD TGFPTD SOI LDMOS was proposed firstly for improve ESD robustness of TGFPTD SOI LDMOS in this paper. The proposed device was obtained by introducing an additional n+ implantation and rapid thermal annealing into the widen p-well region of conventional TGFPTD SOI LDMOS. 2D simulation of the proposed device upon a positive current pulse stimulus of HBM indicates that a hybrid conduction...
In this study, we analyze Net Primary Productivity from 51-year (1950-2000) offline simulations using an Australian land-surface model CABLE (CSIRO Atmosphere Biosphere Land Exchange). The model annual NPP climatology with the estimated 2001 annual NPP from what was derived from a process model driven by remote sensing in deriving China NPP at 1-km resolution. The CABLE results are highly comparable...
Since queueing is a common behavior in computer systems, analysis of queueing models become a mature theory that is widely applied in performance evaluation. In our work, a queueing model based approach is used to manage the performance attributes of a Video On Demand (VOD) back office system, which has been deployed and put into service on a province-scale cable TV network. Extracted from Software...
China education-economy system is typical complex system. Both traditional region economic theory and complex social economic theory were used to analyze it. The econometric equation of system constituents' interactions was built based on the Cobb-Douglas production function. The integrated system model was built according to system dynamics. The simulation indicates that China education-economy system...
Project risk element transmission theory puts forward a new idea of research on project risk management. This paper combined with state transfer diagram, analysed enterprise multi-project management, made concrete exposition on the thought of project chain with different risk element kinds. A tetrahedral structure model of enterprise project chain risk element transmission and controlling mechanism...
While considering the preferential attachment mechanism of networks, the classical BA scale-free network model sets the degrees of nodes in networks as the prime factor to decide the probability of the preferential attachment, whereas the affection of other important information of the structure of networks was ignored. The excellent performance of the Google search engine shows that the PageRank,...
