โœฆ Synopsis

Energy finite element analysis (EFEA) is an efficient way to solve high-frequency structural dynamics response problems. Up to now, EFEA has been used to deal with time-independent vibration problems. However, it is still necessary to understand the time dependent details of energy density distribution of a structure. To study the transient response of a rod under high-frequency sinusoidal excitation, the transient energy density governing equation for a rod is presented. The governing equation is solved, and the solution is verified using an analytical method. Example application to a rod is presented to illustrate the feasibility.

A controlled dynamical system subjected to high-frequency excitations is investigated. A standard controlled system is constructed using a change of variables, which generalizes the Bogolyubov change of variables in the problem of a pendulum with a vibrating suspension point.

The luminescence spectral and kinetic characteristics of CsPbCl 3 nanocrystals, thermally created in a CsCl:Pb single crystal and dispersed in a CsCl matrix, have been studied under excitation by synchrotron radiation in the VUV spectral region (4 to 20 eV). Various components found in the decay kin
