Application of the Sign-Constrained Robust Least-Squares Method to Surveying Networks
Publisher: American Society of Civil Engineers
Abstract: The least-squares (LS) method is highly susceptible to outlying observations. For this reason, various types of robust estimators have been developed; for example,
Rainfall Forecasting with Hybrid and Machine Learning Models Based on Hyperparameter Optimization
Publisher: ASCE
Abstract: Time-series analysis in hydrology plays an important role in the efficient use of water resources, prediction of flood risks, and crop production. However, considering many parameters in the solution of hydrological problems ...
Comparison of Artificial Neural Network and Fuzzy Logic Approaches for the Prediction of In-Cylinder Pressure in a Spark Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In first stage, a machine learning (ML) was performed to predict in-cylinder pressure using both fuzzy logic (FL) and artificial neural networks (ANN) depending on the results of experimental studies in a spark ignition ...
Numerical Simulation of Flow over a Semicylinder Weir
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments are conducted to measure the free-surface profile and the velocity field of an open channel flow over a semicylinder weir. The streamwise velocities of the flow are measured using a laser Doppler ...
Numerical Modeling of Submerged Hydraulic Jump from a Sluice Gate
Publisher: American Society of Civil Engineers
Abstract: The velocity field and surface profile of an open channel flow with a submerged hydraulic jump from a vertical sluice gate are investigated for two different flow cases. The governing equations are numerically solved using ...
Warm Hydromechanical Deep Drawing of AA 5754-O and Optimization of Process Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Warm hydromechanical deep drawing (WHDD) has increasingly been implemented by automotive industry due to its various benefits including mass reduction opportunities in auto body-in-white components and improved formability ...
Numerical Modeling of Submerged Hydraulic Jump from a Sluice Gate
Publisher: American Society of Civil Engineers
Abstract: The velocity field and surface profile of an open channel flow with a submerged hydraulic jump from a vertical sluice gate are investigated for two different flow cases. The governing equations are numerically solved using ...
Design, Fabrication, and Experimental Validation of a Warm Hydroforming Test System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a hydroforming system was designed, built, and experimentally validated to perform lab-scale warm hydromechanical deep drawing (WHDD) tests and small-scale industrial production with all necessary heating, ...
