Response Spectra of Structures under Subway Induced Vibrations
Passing underground trains induce vibrations transmitted to the ground surface and the nearby structures. Ordinarily, these vibrations do not result in structural damage but can harm nonstructural elements and disturb the occupants. These effects are more pronounced when evaluating buildings like hospitals, laboratories, museums, etc., and their assessment is an important design need. To respon...
متن کاملA Galloping Horse Model a Galloping Horse Model
A two-dimensional numerical model of a horse is presented that predicts the locomotory behaviors of galloping horses, including how stride frequency, stride length, and metabolic rate change from a slow canter to a fast gallop. In galloping, each limb strikes the ground sequentially, one after the other, with distinct time lags separating hind and forelimb footfalls. In the model, each stance l...
متن کاملSpin Structures and Spectra
We give necessary and sufficient conditions for the existence of pin ± and spin structures on Riemannian manifolds with holonomy group Z k 2. For any n ≥ 4 (resp. n ≥ 6) we give examples of pairs of compact manifolds (resp. compact orientable manifolds) M1, M2, non homeomorphic to each other, that are Laplace isospectral on functions and on p-forms for any p and such that M1 admits a pin ± (res...
متن کاملAdiabatic Theorems for Dense Point Spectra*
We prove adiabatic theorems in situations where the Hamiltonian has dense point spectrum. The gap condition of the standard adiabatic theorems is replaced by an appropriate condition on the ineffectiveness of resonances.
