We describe a two-layer, coupled model for landslide motion over irregular bathymetry and resulting water column tsunami generation. The three-dimensional non-hydrostatic wave NHWAVE (Ma et al., 2012) is applied as the upper-layer to simulate landslide-generated waves. Here, we focus on derivation of governing equations lower-layer model, where described either viscous mud flow or saturated gra...

Abstract In this paper, a risk sensitive estimator based on cubature quadrature Kalman filter is formulated and applied for tracking ballistic object during its re-entry phase. The algorithm named here as filter. process model measurement two dimensional target motion described. expression noise covariance derived Cartesian coordinate from polar coordinate. Also initial error derived. performan...

The paper is devoted to problems related algebraic decompositions and coordinate representations of tensors with constant components, hemitropic pseudotensors. Such objects tensor algebra are interesting from the micropolar continuum mechanics viewpoint. Algebraic properties pseudotensors components discussed. base examples usable in given. An algorithm for proposed by prof. G.B. Gurevich highl...

A digital moiré technique with circular and radial gratings is proposed to measure in-plane displacement and strain distributions of soft materials in a polar coordinate system. By introducing the coordinate-transform technique, the concentric circles and radial lines in the Cartesian coordinate system are converted to cross gratings in a polar coordinate system. Then, the digital moiré fringes...

This work addresses the problem of resolving kinematic redundancy in legged robots, with the dual goals of maintaining a large reachable workspace and of achieving fast end effector motions in task space. In particular, for robots with four or more legs, gait planning allows for considerable flexibility in the orientation of a stance limb with respect to both body orientation and the ground. By...

A signiicant problem in tracking and estimation is the consistent transformation of uncertain state estimates between Cartesian and spherical coordinate systems. For example, a radar system generates measurements in its own local spherical coordinate system. In order to combine those measurements with those from other radars, however, a tracking system typically transforms all measurements to a...

To assess facial form, one has to determine the size, position, orientation, shape, and symmetry of the different facial units. Many of these assessments require a frame of reference. The customary coordinate system used for these assessments is the 'standard anatomical frame of reference', a three-dimensional Cartesian system made by three planes: the sagittal, the axial, and the coronal. Cons...

The finite element method is a popular numerical in engineering applications. However, there not enough research about the underwater sound propagation. can achieve high accuracy and great universality. We aim to develop three-dimensional model focusing on As foundation of this research, we put forward Cartesian coordinate system for field two-dimensional environment. firstly introduce details ...
