45–60. This box: view. talk. edit. In economics, Kondratiev waves (also called supercycles, great surges, long waves, K-waves or the long economic cycle) are hypothesized cycle-like phenomena in the modern world economy. [1] The phenomenon is closely connected with the technology life cycle. [2] It is stated that the period of a wave ranges ...
The wave crashed over a barrier along the Southern California beach, tossing a wall of fast-moving water at a group of onlookers who rushed to escape the deluge, video taken by Colin Hoag shows. ...
In historical linguistics, the wave model or wave theory (‹See Tfd› German: Wellentheorie) is a model of language change in which a new language feature (innovation) or a new combination of language features spreads from its region of origin, being adopted by a gradually expanding cluster of dialects. Each innovation starts at a certain ...
The Southern Oscillation is the atmospheric component of El Niño. This component is an oscillation in surface air pressure between the tropical eastern and the western Pacific Ocean waters. The El Niño–Southern Oscillation is a single climate phenomenon that periodically fluctuates between three phases: Neutral, La Niña or El Niño. [ 12 ]
September 10, 2024 at 1:29 PM. LOS ANGELES - Crews on Tuesday continued to work to restore power to thousands who lost power during a dangerous heat wave that swept Southern California. By early ...
Boussinesq approximation (water waves) Simulation of periodic waves over an underwater shoal with a Boussinesq-type model. The waves propagate over an elliptic-shaped underwater shoal on a plane beach. This example combines several effects of waves and shallow water, including refraction, diffraction, shoaling and weak non-linearity. In fluid ...
The worst of this week's heat wave is bearing down on Southern California over the next few days.. Forecast. Meteorologists say temperatures could reach between 110 and 115 degrees in the San ...
Cnoidal wave solution to the Korteweg–De Vries equation, in terms of the square of the Jacobi elliptic function cn (and with value of the parameter m = 0.9). Numerical solution of the KdV equation u t + uu x + δ 2 u xxx = 0 (δ = 0.022) with an initial condition u(x, 0) = cos(πx). Time evolution was done by the Zabusky–Kruskal scheme. [1]
