Abstract: An evaluation of publications on reduction of structural eigenvalue problems has revealed the following: (1) Most of the published techniques are essentially equivalent to Guyan reduction; (2) published techniques to ...

Abstract: This note presents a method of reduction for the solution of the eigenproblem in structural dynamics using a modification of the dynamic condensation method. The proposed modification substantially reduces the number of ...

Abstract: Repetitive projects involve the repetition of activities along the stages of the project. Since the resources required to perform these activities move from one stage to the other, a main objective of scheduling these ...

Abstract: Several types of equations have been proposed in the past 30 years to describe the planform of crenulate-shaped bays in static equilibrium: a logarithmic spiral, a parabolic curve, a hyperbolic tangent curve, and a set of ...

Abstract: This experimental study investigates the behavior of void fraction distribution downstream of nonlinear weirs. Systematic air concentration measurements were performed in a 3D array for two model pairs: (1) a piano ...

Abstract: Nonviscously damped vibrating systems are characterized by dissipative mechanisms depending on the timehistory of the response velocity, introduced in the physical models using convolution integrals involving hereditary ...
