The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...
Representation and Processing of Design Standards: a Bifurcation between Research and Practice
There have been attempts to develop representations of design standards and procedures for computing representations of the design standard on which computations are based. However, within...
Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...
Experimental Measurements of Dynamic Loads Imposed by Moving Crowds
Dynamic forces generated by moving occupants were measured using an instrumented forces platform. Experiments were conducted for several sets of loads due to individuals and groups of...
