63Tide — This article is about tides in the Earth s oceans. For other uses, see Tide (disambiguation). Tidal redirects here. For other uses, see Tidal (disambiguation). High Tide redirects here. For other uses, see High Tide (disambiguation) …
64Finite-difference time-domain method — Finite difference time domain (FDTD) is a popular computational electrodynamics modeling technique. It is considered easy to understand and easy to implement in software. Since it is a time domain method, solutions can cover a wide frequency… …
65Computational Aeroacoustics — While the discipline of Aeroacoustics is definitely dated back to the first publication of Sir James Lighthill[1][2] in the early 1950s, the origin of Computational Aeroacoustics can only very likely be dated back to the middle of the 1980s.… …
66Boussinesq approximation (water waves) — In fluid dynamics, the Boussinesq approximation for water waves is an approximation valid for weakly non linear and fairly long waves. The approximation is named after Joseph Boussinesq, who first derived them in response to the observation by… …
67Plasma (physics) — For other uses, see Plasma. Plasma lamp, illustrating some of the more complex phenomena of a plasma, including filamentation. The colors are a result of relaxation of electrons in excited states to lower energy states after they have recombined… …
68M. Salimullah — Professor M. Salimullah, born on January 5, 1949 at Dhaka, Bangladesh, is Dean, Faculty of Physical and Mathematical Sciences and Chairman of Department of Physics in Jahangirnagar University, Bangladesh. passed B.Sc.(Hons) and M.Sc.(Thesis) in… …
69Astronomical seeing — Schematic diagram illustrating how optical wavefronts from a distant star may be perturbed by a layer of turbulent mixing in the atmosphere. The vertical scale of the wavefronts plotted is highly exaggerated. Astronomical seeing refers to the… …
