In order to single out pedestrian crossing from real-life scenarios, this paper does the priori and likelihood modeling in Bayesian framework based on the defined block-based Markov random field. Furthermore, using coarse to fine technique and covariance matrix descriptor, it is focused on the crossing's central position by maximizing a posterior probability. Finally, it spreads around this center...
Through an inter-temporal game between traffic department and tender enterprise, this paper, theoretically studied the general characteristics of the corruption in project bidding in infrastructure construction, and then, setting an example of the traffic infrastructure construction and water infrastructure construction, researched the sectoral characteristics of the corruption in project bidding...
Design of RF pulses for parallel excitation using phased array transmit coils in MRI requires the B1+ maps that are estimated from B1+ mapping experiments. This paper characterizes the effects of B1+ mapping errors on the resulting excitation pattern using a small perturbation analysis based on linearization of the Bloch equation. The accuracy of the proposed perturbation analysis is validated...
Current trends in HPC (high performance computing) suggest that clusters will soon consist with hundreds, if not thousands, processors and the size of current scientific problems becomes much larger than before. Many researchers have predicted that the communication among these processors has dominated the execution time of the scientific parallel applications. Users will need well understanding on...
Original left-inversion soft-sensing method is only suitable for the nonlinear ODE (ordinary differential equations) system, and in this paper the method is expanded to be suitable for a class of nonlinear DAE (differential-algebraic equations) sub-systems. The expansion includes two aspects: (1) The type of the directly measurable variables and the to-be-estimated variables is expanded. For example,...
