WebThe Sound Field for Singularities in Motion Lowson, M. V. A general expression for the sound field of a point force in arbitrary motion is found. The expression reduces to the … WebThis paper proposes an approach to derive the Jacobian matrix of a hybrid mechanism by applying a velocity operator to the transformation matrix. This Jacobian matrix is capable of deducing hybrid singularities, which cannot be identified by using the screw-based Jacobian or velocity-based Jacobian. The transformation matrix was obtained based on the …

Techniques that commonly used to assess the effect of a stress singularity are: 1.Ignore linear-elastically calculated FE stress at a singularity and base engineering decisions on calculated nearby ... WebA gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when".
