To find nontrivial high dimensional integrable models (especially in (3+l)-dimensions) is one of the most important problems in nonlinear physics. A systematic method to find some nontrivial high dimensional integrable models is established by means of noninvertible deformation relations. Starting f rom a noninvertible Miura type transformation, we find that the (l + l)-dimensional sinhGordon m...

A directional morphological operation can be performed by utilizing a rotational structuring element with a directional information, and its associated processing methods for overlapping and enclosing are proposed. As an example of overlapping method derived from the directional morphological operation, a distribution of high/low atmospheric pressures is obtained from the wind direction of weat...

In this study, we deformed the single β phase Mg–Li alloy, Mg–16Li–4Zn–1Er (LZE1641), with conventional rolling (R) and multi-directional (MDR), both at cryogenic temperature. Results showed that nano-precipitation MgZn2 appeared in alloy after MDR, but phenomenon was not present R. The finite element simulation result different deformation modes changed stress distribution inside which affecte...

This paper presents a comprehensive study on bending, vibration and buckling behaviours of the multi-directional FG microplates. The material properties vary continuously both in-plane through-thickness directions. Based quasi-3D shear normal deformation plate theory modified strain gradient theory, finite element model is proposed employed to solve problems microplates with various boundary co...

Detecting objects and estimating their 6D poses is essential for automated systems to interact safely with the environment. Most pose estimators, however, rely on a single camera frame suffer from occlusions ambiguities due object symmetries. We overcome this issue by presenting novel symmetry-aware multi-view estimator called SyMFM6D. Our approach efficiently fuses RGB-D frames multiple perspe...

The ability to accurately and consistently predict deformation of deep foundation pit in civil engineering is required by the designer and manager in planning and conducting construction activities. Since deformation of deep foundation pit that belongs to a multi-variable nonlinear system evolution with time-varying is vague and uncertain, it is prone to a certain degree of prediction errors. T...

The most common parallelization strategy for many Computational Mechanics (typified by Computational Fluid Dynamics(CFD) applications) which use structured grids, involves the one directional partition based upon slads of grids. For parallelised versions of CFD codes to scale well we must employ two (or more) dimensional partitions. However, FORTRAN code implementations by multi-directional par...

This chapter introduces the concept of multi-beam antenna (MBA) in mobile ad hoc networks and the recent advances in the research relevant to this topic. MBAs have been proposed to achieve concurrent communications with multiple neighboring nodes while they inherit the advantages of directional antennas, such as the high directivity and antenna gain. MBAs can be implemented in the forms of mult...
