Unsuitable signalized intersection traffic lights control strategies lead to longer waiting time before vehicles driving through the signal intersections, and the long waiting time brings us many issues, such as traffic jams, more CO2 emissions. Hence how to reduce the waiting time becomes critical. In this paper, we propose a Markov chain based traffic flow evacuation model that aims at minimizing...
Taking the catastrophe theory as a foundation, in the paper a swallowtail catastrophe model of logistics capacity is established for logistics system of national economic mobilization. First the model sets logistics capacity as state variable, and logistic flux change rate, logistic velocity change rate, time change rate as three control variables. Next, the break points and its steady points of logistic...
According to a new horizontal moving mechanism called `Side-Wheel Operating Simultaneously', the moving process of the high-speed & high acceleration stacker for starting and accelerating was simulated and analyzed with multi-body system method. The result showed that the stacker is able to accelerate stably and fast with the designed maximum acceleration and speed.
UAV low-altitude remote sensing develops rapidly. Because of the characteristics such as unstable flight attitude, low-level image automatic matching and large image distortion, there are still just a few successful researches in efficient image stitching and image correction. So this paper takes UAV (Unmanned Aviation Vehicle) image in Jiuyuangou Township, Suide County, Yulin City, Shanxi Province...
A queuing system model was established by analyzing the characteristics of the Battle Damaged Aircraft Repairing(BDAR), and then some system function targets were gotten, such as average queuing length and average queue waiting time and so on. Then the service ability of repairing institution was analyzed, and the scale of force for Battle Damage Aircraft Repairing, which is the basis of the decision-making...
In this paper, we propose a new variant of latent Dirichlet allocation (LDA): Collective LDA (C-LDA), for multiple corpora modeling. C-LDA combines multiple corpora during learning such that it can transfer knowledge from one corpus to another; meanwhile it keeps a discriminative node which represents the corpus ID to constrain the learned topics in each corpus. Compared with LDA locally applied to...
