With the consideration of magnetic force, the interaction model is developed. Numerical simulations are performed to study the dynamic characteristics of the bridge during vehicle movement along the bridge. The results show that a reasonable value of the linear stiffness ratio of columns to beams is between 2. 0 and 3.0. The dynamic responses of the bridge are aggravated with the decrease in bending rigidity and the increase in vehicle speed and the span ratio of the bridge. It is suggested that a definite way is to control impact coefficients and acceleration in the dynamic design of the bridge. It is unsuitable to adopt the moving load model and the moving mass model in the design. The proposed results can serve in the design of high-speed maglev three-span rigid frame bridges.展开更多

Recent efforts indicate that the convergence guarantee of the imaging algorithms using plug-andplay priors relies on the assumption of bounded denoisers. However, the bounded properties of existing plugged Gaussian denoisers have not been proven explicitly. To bridge this gap, we detail a novel provable bounded denoiser termed as BMDual,which combines a trainable denoiser using dual tight frames and the well-known block-matching and 3D filtering(BM3D)denoiser. We incorporate multiple dual frames utilized by BMDual into a novel regularization model induced by a solver. The proposed regularization model is utilized for compressed sensing magnetic resonance imaging(CSMRI). We theoretically show the bound of the BMDual denoiser, the bounded gradient of the CSMRI data-fidelity function, and further demonstrate that the proposed CSMRI algorithm converges. Experimental results also demonstrate that the proposed algorithm has a good convergence behavior, and show the effectiveness of the proposed algorithm.展开更多

We show that the impact of angular velocity in the former is equivalent to the impact of the magnetic field in the latter. We consider scenarios conducive to comparable trajectories for these two distinct areas of physics. We extend the analysis considering two separate routes. For the rotating frame we investigate the impact of friction and for the magnetic field the effect of field in-homogeneities. We utilize Mathematica [1] throughout, most notably for solving coupled partial differential equations.展开更多

The frame number is a unique number used in the vehicle, and by identifying it can quickly find out the vehicle models and manufacturers. The traditional character recognition method has the problem of complex feature extraction, and the convolutional neural network has unique advantages in processing two-dimensional images.

The novella＇s allusions to a Buddhist-like epistemology, together with its subtle references to Scandinavian myths, however, have so far remained uncovered and are therefore best approached in the light of what has been called ＂the suppressed intertextuality in post-colonial writing＂. The author＇s intention in this paper is twofold： On the one hand, the author will suggest that post-colonial writers do not necessarily write against the Western canon and that maintaining the contrary amounts to vindicating the centrality of imperial texts in the contemporary literary scene--an endeavour which is hardly post-colonial. On the other hand, the author will go some way towards shifting eastward the core of Frame＇s ontology by suggesting that her poetics is anchored not only in Western thinking, but also, perhaps more importantly so, in Eastern philosophy. The author＇s primary impulse, however, in examining the interplay between canonical and peripheral intertextualities, is to illuminate in fundamental fashion the haunting beauty of the writer＇s universe and the lyricism of Snowman, Snowman.展开更多
