Students can predict results of changes in the mode
Model testing of passive site stabilization
Passive site stabilization is a new technology proposed for use in mitigation of liquefaction risk at developed sites. Liquefaction is the rapid loss of strength caused by earthquakes, typically found in saturated sands or loose fills, which causes the formation to flow like later. Liquefaction has been known to be a very costly occurrence claiming many lives, damaging structures and businesses, and costing billions of dollars in repairs; however, sites can be remediated to prevent liquefaction.

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.
Active galaxies provide a prime example of high energy processes operating in the Universe. This unit gives an overview of active galaxies, including the supermassive black holes that power the engines at their centres, and the emission processes by which we detect and study them. It also gives practice in mathematical techniques for analysing data and theoretical models.
Coordination problem is a blog produced by a team of US based professional economists from the Austrian school commenting on scholarly research in economics and current events. It promotes the work of Hayek, Mises, Kirzner and others of the Austrian school - a non-mainstream (heterodox) schools of economists, who advocate that the complexities of human economic behaviour makes the mathematical modelling of markets extremely difficult. The blog features links to related blogs, internet websites a
