Flow-induced vibration of steam generator (SG) tubes may sometimes result in fretting-wear damage at the tube-to-support locations. Fretting-wear damage predictions are largely based on experimental data obtained at representative test conditions. Fr

It has been suggested that the 30-item version of the Boston Naming Test (BNT), in which either the odd or even items from the standard 60-item test are given, is the most psychometrically sound short form. However, no normative data are available fo

Flow-induced vibration of steam generator tubes results in fretting-wear damage due to impacting and rubbing of the tubes against their supports. This damage can be predicted by computing tube response to flow-induced excitation forces using analytic

Fretting-wear of nuclear heat exchange equipment is addressed at the design stage to demonstrate that components will meet their design life. Atomic Energy of Canada Limited (AECL) has developed a methodology to predict the progression of fretting-we

Tubes within tube and shell heat exchange components are supported at intermediate points by support plates. Flow-induced vibration of a tube can cause it to impact or rub against a support plate or against adjacent tubes and can result in tube frett

The effect of surface layers on the thermal constriction resistance of contacts is of interest to the thermal analyst. This paper investigates analytically and experimentally the thermomechanical problem of a sphere in elastic contact with a flat coa

The inverse gravity problem is posed as a linear least‐squares problem with the variables being densities of two‐dimensional prisms. Upper and lower bounds on the densities are prescribed so that the problem becomes a linearly constrained least

Tubes within tube and shell heat exchangers are supported at intermediate points by plates. Flow-induced vibration can cause tubes to impact and rub against these supports, or other tubes, and can result in tube fretting-wear. The tube-to-support dyn

The inversion and forward modeling approaches to interpretation are separated by a vast philosophical gulf, and mathematicians and geologists standing on opposite sides of this gulf find it difficult to see the other side. The use by Fisher and Howar
