RISGenetic Algorithm to Optimize Layer Parameters in Light Weight Deflectometer Backcalculation
Publisher: American Society of Civil Engineers
Abstract: The light weight deflectometer (LWD) is a portable, nondestructive testing device that can estimate pavement layer parameters, namely moduli. Conventional backcalculation of layer parameters from LWD deflections is formulated ...
Determination of Essential Orders From a Bond Graph Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The notion of essential orders was first introduced for the handling of decoupling problems. This paper focuses more on their interpretation, namely on the fact that each essential order ...
