A Kriging Metamodel with Adaptive Sampling for Seismic Evaluation of Podium Buildings
Yuying Huang, Zhiyong Chen, Samuel W. K. Wong
In this paper, nonlinear time-history dynamic analyses of selected earthquake ground motions are conducted on designated wood-frame podium buildings and the resulting inter-story d…
Monte Carlo sampling of flexible protein structures: an application to the SARS-CoV-2 omicron variant
Samuel W. K. Wong
Proteins can exhibit dynamic structural flexibility as they carry out their functions, especially in binding regions that interact with other molecules. For the key SARS-CoV-2 spik…
Multimodel Bayesian Analysis of Load Duration Effects in Lumber Reliability
Yunfeng Yang, Martin Lysy, Samuel W. K. Wong
This paper evaluates the reliability of lumber, accounting for the duration-of-load (DOL) effect under different load profiles based on a multimodel Bayesian approach. Three indivi…
Comparing regional and provincial-wide COVID-19 models with physical distancing in British Columbia
Geoffrey McGregor, Jennifer Tippett, Andy T. S. Wan +2
We study the effects of physical distancing measures for the spread of COVID-19 in regional areas within British Columbia, using the reported cases of the five provincial Health Au…
Statistical challenges in the analysis of sequence and structure data for the COVID-19 spike protein
Shiyu He, Samuel W. K. Wong
As the major target of many vaccines and neutralizing antibodies against SARS-CoV-2, the spike (S) protein is observed to mutate over time. In this paper, we present statistical ap…
Calibrating wood products for load duration and rate: A statistical look at three damage models
Samuel W. K. Wong
Lumber and wood-based products are versatile construction materials that are susceptible to weakening as a result of applied stresses. To assess the effects of load duration and ra…
Where Does Haydn End and Mozart Begin? Composer Classification of String Quartets
Katherine C. Kempfert, Samuel W. K. Wong
For centuries, the history and music of Joseph Franz Haydn and Wolfgang Amadeus Mozart have been compared by scholars. Recently, the growing field of music information retrieval (M…
Sequential Decision Model for Inference and Prediction on Non-Uniform Hypergraphs with Application to Knot Matching from Computational Forestry
Seong-Hwan Jun, Samuel W. K. Wong, James V. Zidek +1
In this paper, we consider the knot matching problem arising in computational forestry. The knot matching problem is an important problem that needs to be solved to advance the sta…
The duration of load effect in lumber as stochastic degradation
Samuel W. K. Wong, James V. Zidek
This paper proposes a gamma process for modelling the damage that accumulates over time in the lumber used in structural engineering applications when stress is applied. The model…
Dimensional and statistical foundations for accumulated damage models
Samuel W. K. Wong, James V. Zidek
This paper develops a framework for creating damage accumulation models for engineered wood products by invoking the classical theory of non--dimensionalization. The result is a ge…
Bayesian analysis of accumulated damage models in lumber reliability
Chun-Hao Yang, James V. Zidek, Samuel W. K. Wong
Wood products that are subjected to sustained stress over a period of long duration may weaken, and this effect must be considered in models for the long-term reliability of lumber…
