A Simulation to Noise Barrier
The problem related to noise barrier is simulated by a still, single frequency, three dimensional sound source located within two parallel screens with rigid back walls. The solution of...
Time-Domain Transmitting Boundary Condition in Fluid-Structure Interaction Studies
One of the major difficulties in the nonlinear analyses of fluid-structure interactions has been the lack of exact expressions for the transmitting boundary in the time domain. Researchers...
Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...
Highway Robbery: The Social Costs of Hazardous Materials Incidents on the Capital Beltway
