RISAsymmetric Error Functions for Reducing the Underestimation of Local Scour around Bridge Piers: Application to Neural Networks Models
Publisher: American Society of Civil Engineers
Abstract: Many of the empirical formulas used for the prediction of the expected scour depth at piers are excessively conservative, providing substantial overestimations. On the other hand, the recently proposed neural networks ...
pH-Stat Titration to Assess Nitrification Inhibition
Publisher: American Society of Civil Engineers
Abstract: This paper describes a standardized method to assess the inhibitory effect of a toxicant on nitrifying microorganisms. Nitrification activity is measured by means of pH-stat titration, which exploits the stoichiometric ...
Social Media as a Source of Meteorological Observations
Publisher: American Meteorological Society
Abstract: An increasing number of people leave their mark on the Internet by publishing personal notes (e.g., text, photos, videos) on Web-based services such as Facebook and Flickr. This creates a vast source of information that ...
Damage Detection for a Cantilevered Steel I-Beam through Deep-Learning Methods: LSTM, Multivariate Time-Series Transformer, and LSTM-Based Autoencoder
Publisher: American Society of Civil Engineers
Abstract: The structural integrity of steel trusses and I-beams is of vital importance for preventing the potential collapse of steel bridges when subjected to extraordinary forces. Thus, identifying damage to I-beams, which cannot ...
Control Surface Approach for Inlet Control Performance of Pipe Culverts: Comparison of Experimental Data and Design Frameworks
Publisher: American Society of Civil Engineers
Abstract: Culverts are widely used hydraulic structures, and commonly are designed using the Federal Highway Administration (FHWA) or USGS frameworks. This paper presents the control surface method (CSM), a generalized method for ...
The Signature of ENSO in Global Temperature and Precipitation Fields Derived from the Microwave Sounding Unit
Publisher: American Meteorological Society
Abstract: Global temperature anomalies associated with ENSO are investigated, making use of a 13-year record of gridded temperature and precipitation data from the microwave sounding unit (MSU). The warm phase of the ENSO cycle ...
Effects of ice Formation on Convective Cloud Development
Publisher: American Meteorological Society
Abstract: A study is performed of the importance of the ice-phase formation in convective cloud development. With this purpose, a one-dimensional and time-independent cloud model is applied to radiosonde data, corresponding to ...
Modeling and Optimization of Acid Blue 193 Removal by UV and Peroxydisulfate Process
Publisher: American Society of Civil Engineers
Abstract: In this study, the advanced oxidation process for dye removal from textile wastewater treatment was investigated by means of an experimental setup in which the effect of several parameters on dye removal efficiency ...
A Mechanical Characterization of the Porcine Atria at the Healthy Stage and After Ventricular Tachypacing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Atrial fibrillation (AF) is a cardiac arrhythmia that highly increases the risk of stroke and is associated with significant but still unexplored changes in the mechanical behavior of the tissue. ...
