G. K. Patterson,G. L. Florezntains several results showing that the inference of indices in computable numberings can differ very much. For instance, there are computable numberings which are difficult for the inference, and only finite classes of total recursive functions can be identified. This shows that computable numberin作者: sed-rate 時間: 2025-3-22 18:04 作者: 柔聲地說 時間: 2025-3-22 23:27

On the Many Faces of Transitionnd a number of unifying conjectures are advanced for subsonic speeds. In particular, the roles of linear amplification, nonlinear limiting, and secondary instability inducted by unsteady nonlinear effects are discussed.

Exploratory Drag Reduction Studies in Non-Polar Soap Systemsese non-polar systems indicate that they were not at equilibrium. It is believed that the differences in the nature of the soap structure in solution for the two types of systems cause the observed differences in the turbulent flow behavior.作者: 扔掉掐死你 時間: 2025-3-24 11:48

The Onset of Dilute Polymer Solution Phenomena and three types of onset hypotheses are evaluated against experimental data. A semi-empirical correlation is presented for onset in pipes.
