Effects of Topography on Seismic-Wave Propagation: An Example from Northern Taiwan [PDF]

, 2009
Topography influences ground motion and, in general, increases the amplitude of shaking at mountain tops and ridges, whereas valleys have reduced ground motions, as is observed from data recorded during and after real earthquakes and from numerical ...

The Effect of Magnitude M_w and Distance R_rup on the Fragility Assessment of a Multistory RC Frame Due to Earthquake-Induced Structural Pounding

Buildings, 2023
The effect of an intensity measure’s (IM’s) sufficiency property on the probabilistic assessment of reinforced concrete (RC) structures due to floor-to-floor structural pounding conditions is examined.

Cooling trapped atoms in optical resonators [PDF]

, 2007
We derive an equation for the cooling dynamics of the quantum motion of an atom trapped by an external potential inside an optical resonator. This equation has broad validity and allows us to identify novel regimes where the motion can be efficiently ...

VIBE: Video Inference for Human Body Pose and Shape Estimation

, 2020
Human motion is fundamental to understanding behavior. Despite progress on single-image 3D pose and shape estimation, existing video-based state-of-the-art methods fail to produce accurate and natural motion sequences due to a lack of ground-truth 3D ...

A Framework for Evaluating Motion Segmentation Algorithms

, 2017
There have been many proposals for algorithms segmenting human whole-body motion in the literature. However, the wide range of use cases, datasets, and quality measures that were used for the evaluation render the comparison of algorithms challenging. In
