RISMachine Learning for Modeling Water Demand
Publisher: American Society of Civil Engineers
Abstract: This work shows the application of machine learning (ML) methods to the modeling of water demand for the first time. Classification and regression trees (CART) and random forest (RF), a multivariate, spatially nonstationary ...

Buried Pipe Modeling With Initial Imperfections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A formulation using the finite element method is presented in this paper to analyze stresses and displacements of underground pipelines with initial imperfections. The formulation includes both ...
Mechanical Stresses in Abdominal Aortic Aneurysms: Influence of Diameter, Asymmetry, and Material Anisotropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biomechanical studies suggest that one determinant of abdominal aortic aneurysm (AAA) rupture is related to the stress in the wall. In this regard, a reliable and accurate stress analysis of ...
Design of Fused-Deposition ABS Components for Stiffness and Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The high degree of automation of Solid Freeform Fabrication (SFF) processing and its ability to create geometrically complex parts to precise dimensions provide it with a unique potential for ...
Trust Region Augmented Lagrangian Methods for Sequential Response Surface Approximation and Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A common engineering practice is the use of approximation models in place of expensive computer simulations to drive a multidisciplinary design process based on nonlinear programming techniques. ...
Unsteady Bed Shear Stresses Induced by Navigation: Laboratory Observations
Publisher: American Society of Civil Engineers
Abstract: Time-dependent bed shear stresses induced by the passage of a barge tow have been measured with hot film shear stress sensors in a 1:25 scale model. Conditions typical of those observed for Upper Mississippi River navigation ...
Consistent Software-Specific Nonlinear Dynamic Response of Highway Bridges
Publisher: ASCE
Abstract: Compared to linear analysis approaches, nonlinear analysis of bridge models under large seismic demands has enabled more realistic prediction of global and local responses. However, the sensitivity to modeling assumptions, ...
On the Determination of Softening Parameters for Nonlocal Constitutive Models
Publisher: American Society of Civil Engineers
Abstract: Several regularized formulations exist in the literature, such as nonlocal constitutive models, for the objective simulation of localized deformations in quasibrittle materials that prevent the well-known pathological ...
Transmural Strains in the Ovine Left Ventricular Lateral Wall During Diastolic Filling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rapid early diastolic left ventricular (LV) filling requires a highly compliant chamber immediately after systole, allowing inflow at low driving pressures. The transmural LV deformations associated ...
