RISNovel Sparse Bayesian Learning and Its Application to Ground Motion Pattern Recognition
Publisher: American Society of Civil Engineers
Abstract: A novel sparse Bayesian learning for correlated error (SBL-CE) algorithm is proposed to automatically search for an optimal model class with relevance features in regression problems of pattern recognition based on measured ...
Novel Outlier-Resistant Extended Kalman Filter for Robust Online Structural Identification
Publisher: American Society of Civil Engineers
Abstract: Structural health monitoring (SHM) using dynamic response measurement has received tremendous attention over the last decades. In practical circumstances, outliers may exist in the measurements that lead to undesirable ...
Scale Independent Linear Behavior of Alluvial Channel Flow
Publisher: American Society of Civil Engineers
Abstract: For flow in a rigid open channel with no bed sediment, the achievement of the special state of stationary equilibrium yields a linear characteristic. To examine the existence of a linear characteristic in alluvial channel ...
Stable Robust Extended Kalman Filter
Publisher: American Society of Civil Engineers
Abstract: In this paper, a stable and robust filter is proposed for structural identification. This filter resolves the instability problems of the traditional extended Kalman filter (EKF). Instead of ad hoc assignment of the noise ...
Microphysical and Turbulent Structure of Nocturnal Stratocumulus as Observed during ASTEX
Publisher: American Meteorological Society
Abstract: Measurements of the microphysical and turbulence structure of stratocumulus made during the Atlantic Stratocumulus Transition Experiment are presented. The measurements made from a C-130 aircraft, belonging to the ...
Joint Prediction of Remaining Useful Life and Failure Type of Train Wheelsets: Multitask Learning Approach
Publisher: American Society of Civil Engineers
Abstract: Train wheel failures account for disruptions of train operations and even a large portion of train derailments. Remaining useful life (RUL) of a wheelset measures how soon the next failure will arrive, and the failure type ...
Short-Term and Long-Term Surface Soil Moisture Memory Time Scales Are Spatially Anticorrelated at Global Scales
Publisher: American Meteorological Society
Abstract: AbstractLand?atmosphere feedbacks occurring on daily to weekly time scales can magnify the intensity and duration of extreme weather events, such as droughts, heat waves, and convective storms. For such feedbacks to occur, ...
Bayesian Learning–Based Data Analysis of Uniaxial Compressive Strength of Rock: Relevance Feature Selection and Prediction Reliability Assessment
Publisher: ASCE
Abstract: Estimation on the uniaxial compressive strength (UCS) of rock is an important issue in geotechnical engineering. Empirical relation establishment for UCS estimation is particularly favorable since core sample measurement ...
Stability Analysis of Long-span Deck-type CFST Arch Bridge
Publisher: American Society of Civil Engineers
Abstract: With the application of the concrete-filled-steel tube (CFST) in civil engineering, which is a composition material, the overcrossing ability of arch bridge get advanced development. For long-span and small width-span ratio ...
Mechanisms and Early Warning of Drought Disasters: Experimental Drought Meteorology Research over China
Publisher: American Meteorological Society
Abstract: AbstractA major experimental drought research project entitled ?Mechanisms and Early Warning of Drought Disasters over Northern China? (DroughtEX_China) was launched by the Ministry of Science and Technology of China in ...
