Learned helplessness in the rat: Effect of response topography in a within-subject design
(ELSEVIER SCIENCE BV, 2011)
Three experiments investigated learned helplessness in rats manipulating response topography within-subject and different intervals between treatment and tests among groups. In Experiment 1, rats previously exposed to ...
Site specific analysis using topography conditioned response spectra
(Elsevier LtdUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2019-01-01)
We address topographic effects in site response analysis. By splitting a generalized surface topography into simple geometric elements we identify fundamental concepts that control the dynamic response. We show that in the ...
Effects of realistic topography on the ground motion of the Colombian Andes - A case study at the Aburra Valley, Antioquia
(OXFORD UNIV PRESSUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2016-03-01)
This paper presents a set of deterministic 3-D ground motion simulations for the greater metropolitan area of Medellin in the Aburra Valley, an earthquake-prone region of the Colombian Andes that exhibits moderate-to-strong ...
Implant surface features as key role on cell behavior
(2022-01-01)
It has been recognized that physical and chemical properties of biomaterial surfaces mediate the quality of extracellular matrix (ECM) that may affect cell behaviors. In nature, ECM is a heterogeneous three-dimensional ...
Effects of topography on 3D seismic ground motion simulation with an application to the Valley of Aburrá in Antioquia, Colombia
(Universidad EAFITMaestría en IngenieríaEscuela de Ingeniería, 2013)
This dissertation presents a numerical scheme based upon the finite element framework for the numerical modeling of earthquake-induced ground motion in the presence of realistic topographic variations of the Earth’s crust ...
On the contact stiffness and nonlinear vibration of an elastic body with a rough surface in contact with a rigid flat surface
(Elsevier B.V., 2015-01-01)
The surface topography of engineering rough surfaces has an enormous influence on contact mechanics of the interface and further the dynamics of the contact system. In this paper, the force-deflection characteristic and ...

Numerical simulations of comminution slurries over complex topographies: Putting together CFD and pipeline integrity
(Elsevier, 2014)
The use of computational fluid dynamics gives new and interesting insights for risk analysis of crosscountry
ore hydraulic transport operations. In particular, they offer the possibility to predict, with reasonable
accuracy, ...
