Sensors that detect changes in atmospheric pressure due to ground shaking can also obtain data about large earthquakes and explosions that exceed the upper limit of many seismometers, according to new ...

Dynamic analyses can tell a lot about a design without building physical models. Determining whether or not a mechanism will work before building physical prototypes can be time consuming and ...
