The dynamical motion of a pair microparticles exposed to acoustic standing waves and located at the pressure nodal plane is studied using numerical simulations experiments. insight into their behavior along due competition between axial primary radiation interparticle forces elucidated. An expression for force acting on particle derived, dynamics simulated fluid-structure interaction model base...

− In this paper, we describe a parallel solution scheme for inverse dynamics, and its application to feed-forward control of link mechanisms under various boundary conditions. The conditions include such cases as openand closed-loops, and even one that continuously changes its form from an opento a closed-loop. The dynamic equations conducted by generally used schemes such as the Newton-Euler m...

Abstract Consistent transmitting boundaries for time‐domain analyses of scalar‐ and elastic‐wave propagation in horizontally layered anisotropic or transversely isotropic waveguides are developed. Governing equations corresponding consistent nodal forces derived scalar elastic waves which finite‐element discretization is considered the vertical layering direction. Auxiliary variables horizontal...

The usual explanation of the gradient-weighted moving finite element (GWMFE) method has been in terms of its variational interpretation. This paper presents a more intuitive geometrical-mechanical interpretation of GWMFE as a balance of forces on the nodes, forces concentrated onto the nodes by the laws of leverage. It also presents significant simplifications in the “internodal viscosity” term...

This paper describes a three-dimensional parallel solution scheme for inverse dynamics of link mechanisms, which has already been proposed for the two-dimensional case and applied in several inplane motions. In this theory, the entire system is subdivided into finite elements and evaluated as a continuum. A single-link structure of a pin joint and a rigid bar is expressed using the Shifted Inte...

In this paper, an inverse nodal problem for a second-order differential equation having a chemical potential on a finite interval is investigated. First, we estimate the nodal points and nodal lengths of differential operator. Then, we show that the potential can be uniquely determined by a dense set of nodes of the eigenfunctions.

the natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. tire rubber materials and cord layers are represented independently using “shell element” available in cosmos. the effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural fre...

The mouse transcription factor Noto is expressed in the node and controls node morphogenesis, formation of nodal cilia and left-right asymmetry. Noto acts upstream of Foxj1, which regulates ciliogenesis in other mouse tissues. However, the significance of Foxj1 for the formation of cilia in the mouse node is unclear; in non-amniote species Foxj1 is required for ciliogenesis in the structures eq...
