Finite amplitude thermal convection with variable gravity
International Journal of Mathematics and Mathematical Sciences, 2001 Finite amplitude thermal convection is studied in a horizontal layer of infinite Prandtl number fluid with a variable gravity. For the present study, gravity is restricted to vary quadratically with respect to the vertical variable.

Close frequency pairs in Delta Scuti stars [PDF]
, 2002 The majority of the well-studied Delta Scuti stars show frequency pairs in the power spectra with frequency separations less than 0.06 c/d(0.7 microHz) as well as amplitude variability.

Three-graviton amplitude in Berkovits–Vafa–Witten variables [PDF]
Physics Letters B, 2002 We compute the three-graviton tree amplitude in Type IIB superstring theory compactified to six dimensions using the manifestly (6d) supersymmetric Berkovits-Vafa-Witten worldsheet variables. We consider two cases of background geometry: the flat space example R6xK3, and the curved example AdS3xS3xK3 with Ramond flux, and compute the correlation ...

Some Aspects of Variable Amplitude Fatigue [PDF]
International Journal of Metallurgy and Metal Physics, 2019 Fatigue crack growth behavior of selected aluminum alloys under variable amplitude loading is discussed in this study, based principally on experimental observations. The tests include single overloads tests in different environments, and tests using an aircraft wing loading spectrum.
