Dynamics of Flexible Hose Riser Systems

The paper describes a highly effective method for computing the dynamics of the catenary-shaped suspension of flexible hose systems. The method accounts for a number of nonlinearities, it is 3-dimensional and it is performed in the time domain. The paper addresses the analysis method and demonstrates its effectiveness on a sample flexible riser analysis.

Independent space variables for small-signal electron beam analyses

This paper gives a systematic account of three systems of independent space variables useful in small signal electron beam analyses--the familiar Eulerian, polarization, and hose systems. The continuity, dynamical, and power exchange equations are given for each of the three sets of variables, and the relative merits of each system are discussed. The inapplicability of the Lagrangian system to small signal beam problems is also indicated.
