The hydrodynamic mass approach to the solution of dynamic problems in coupled fluid-cylindrical shells is reviewed; simplified equations for computing the hydrodynamic masses and for the subsequent solution of the eigenvalue problem are given in several commonly encountered special cases. Methods of incorporating the hydrodynamic mass concept into finite element structural analysis computer programs for the more general cases are discussed.

Diffraction Patterns

Electron diffraction is one of most widely used techniques in the characterization of specimens in the TEM. With the advent of computerization, there is a growing trend toward automation of the measurement and analysis of electron diffraction patterns (EDPs). There are a number of computer programs used for measuring, indexing, and simulating EDPs, some of which are now commercially available. Many of these programs are stand-alone programs which either perform a specific aspect of EDP analysis or require significant user interaction, particularly in the measurement phase. In some cases, the lack of suitable algorithms for measuring EDPs usually limit these programs to the extent that users still have to perform standard procedures of measuring EDPs from negatives or prints to obtain the necessary values needed to complete the execution of these programs. Here, a more convenient means for online acquisition and measurement of EDPs is presented.
