Formation of internal shock waves in bent jets
We discuss the circumstances under which the bending of a jet can generate an internal shock wave. The analysis is carried out for relativistic and non–relativistic astrophysical jets. The calculations are done by the method of characteristics for the case of steady simple waves. This generalises the non–relativistic treatment first used by Icke (1991). We show that it is possible to obtain an ...
متن کاملBent waveguides for matter-waves: supersymmetric potentials and reflectionless geometries
Non-zero curvature in a waveguide leads to the appearance of an attractive quantum potential which crucially affects the dynamics in matter-wave circuits. Using methods of supersymmetric quantum mechanics, pairs of bent waveguides are found whose geometry-induced potentials share the same scattering properties. As a result, reflectionless waveguides, dual to the straight waveguide, are identifi...
متن کاملDamage detection in bent plates using shear horizontal guided waves.
Study of the interaction of shear horizontal guided mode with defects in the bend region of an isotropic top hat stiffener is presented. Compared with the SH0 wave in a plate, the shear mode in the bend is dispersive and its wavefield characteristics are affected by the curvature of the bend. The scattering studies showed that the sensitivity of the wave to outer surface cracks in the bend incr...
متن کاملBent and generalized bent Boolean functions
In this paper, we investigate the properties of generalized bent functions defined on Z2 with values in Zq , where q ≥ 2 is any positive integer. We characterize the class of generalized bent functions symmetric with respect to two variables, provide analogues of Maiorana–McFarland type bent functions and Dillon’s functions in the generalized set up. A class of bent functions called generalized...
متن کاملSpecial bent and near-bent functions
Starting from special near-bent functions in dimension 2t − 1 we construct bent functions in dimension 2t having a specific derivative. We deduce new families of bent functions.
