Near-real-time Identification of Seismic Damage by Graph Neural Network based on Structural Modes
(2023)This paper proposes a near-real-time damage identification method based on the graph neural network (GNN) using the structural response data recorded during an earthquake event. The proposed method features a structural-mode-based ... -
Near-real-time online process control using grey-box models
(2023)Near-real time control of dynamical processes is very beneficial as it enables detection and timely intervention in case of diminishing quality or necessary parameter adjustment. This can improve quality and reliability, ... -
Network Analysis of Systems of Systems Models for Complex Infrastructure Systems
(2023)Complex infrastructure systems, such as transportation and communication networks, consist of many interconnected and interdependent elements that exhibit behavior that is difficult to predict. Researchers have developed ... -
Network Reliability Analysis and Complexity Quantification Using Bayesian Network and Dual Representation
(2023)Modern society operates upon various lifeline networks such as transportation networks, power networks, and gas distribution networks. To secure their reliable operations, it is critical to evaluate their reliability. ... -
New insights for chemical-physical processes from analysis of observations using extreme value probability distributions
(2023)Conventional extreme value (EV) theory has the Gumbel EV distribution as the theoretically correct distribution to represent the maximum depth of corrosion pits. It has long been used for prediction of the probability of ... -
New opportunities for bridge management using independent datasets
(2023)Bridge managers have increasingly utilised databases to aid in the efficient allocation of resources. For the most part, these databases have been compiled from existing bridge management tools such as bridge inspection ... -
New versus Previous ASCE 7-16 Earthquake Loads for 500 Overseas Locations
(2023)The American Society of Civil Engineers (ASCE) Earthquake Loads Overseas project is an ongoing collaboration between the U.S. Geological Survey (USGS) and the Global Earthquake Model (GEM) Foundation to compute Risk-targeted ... -
Next Generation Community-Level Resilience Modeling: The Interdependent Networked Community Resilience Modeling Environment (IN-CORE)
(2023)In 2015, the U.S National Institute of Standards and Technology (NIST) funded the Center of Excellence for Risk-Based Community Resilience Planning (CoE), a 14 university-based consortium of almost 100 people, including ... -
Nitrate responses in groundwater under grassland dairy agriculture
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2004)A considerable body of research already exists on establishing nitrate dynamics in agricultural systems' subsoils. However, the capacity to predict rates of nitrogen arrival at the receiving environment, namely surface or ... -
Non-stationary response autocorrelation function of nonlinear oscillators endowed with fractional derivative elements
(2023)An approximate analytical technique is developed for determining the non-stationary response autocorrelation function of nonlinear oscillators endowed with fractional derivative elements. Specifically, first, a stochastic ... -
Nonlinear Damage Identification in Fiber-reinforced Cracked Composite Beams through Time-space Wavelet Analysis
(2014)It is well-known that wavelet analysis is, in the space domain, an efficient way to determinate the damage location (Pakrashi et al., 2007; Loutridis et al., 2004), while, in the time domain, it is an efficient tool to ... -
Nonlinear model predictive control to reduce pitch actuation of floating offshore wind turbines
(2020)Modern-day wind turbines use active pitch control to reduce mechanical loads on the turbines in addition to regulating generator power. These control algorithms increase blade pitch actuation, primarily to reduce the 1P ... -
Nonlinear Model-Data Fusion with Minimal Sensing for Performance-Based Seismic Monitoring of Instrumented Buildings
(2023)This paper presents a new concept for performance-based monitoring (PBM) of instrumented buildings subject to earthquakes. This concept is achieved by simultaneously combining and advancing existing knowledge from structural ... -
Numerical and Experimental Investigation of the Seismic Performance of Steel Concentrically Braced Frame Structures
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2019)The concepts of performance-based earthquake engineering (PBEE) and performance based seismic design (PBSD) emerged after the 1994 Northridge and 1995 Kobe earthquakes, where the level of damage to structures, economic ... -
Numerical modelling of the passive control of air pollution in asymmetrical urban street canyons using refined mesh discretization schemes
(2012)This study evaluates the potential of passive controls in asymmetrical street canyons to reduce personal exposure to air pollutants on footpaths. A passive control in the form of a low boundary wall (LBW) may act as a ... -
Nutrient loading on subsoils from on-site wastewater effluent, comparing septic tank and secondary treatment systems
(2009)The performance of six separate percolation areas was intensively monitored to ascertain the attenuation effects of unsaturated subsoils with respect to on-site wastewater effluent: three sites receiving septic tank effluent, ...
