RISRevisiting the Calibration Philosophy of Constitutive Models in Geomechanics
Publisher: American Society of Civil Engineers
Abstract: Conventional laboratory tests in geomechanics are inherently designed to create a uniform stress–strain field whereby relative homogeneity in data prevails at the expense of information diversity. The one-element convenience ...
Multiscale Multiphysics Modeling, Analysis, Simulation, and Fabrication of Carbon Nanotube-Based Integrated Power Inductor for System On-Chip With Magnetic Cores
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The magnetics of power electronics has particular potential for improvement, as these components are typically the largest and volumetrically inefficient in a power circuit. Nowadays, the trend ...
Integrated Model for Optimizing Orientation of Two-Runway Configurations
Publisher: American Society of Civil Engineers
Abstract: This paper presents an integrated computer model (WNDROS2) for optimizing runway orientation at airports having two-runway configurations. In this model, mathematical formulation is applied to transfer circles and radial ...
Analysis and Modeling of Measured Delays at Isolated Signalized Intersections
Publisher: American Society of Civil Engineers
Abstract: Vehicular delay is an excellent tool for evaluating the operation of signalized intersections. This paper presents a methodology for measuring and analyzing stopped delay as well as acceleration and deceleration delay at ...
Simulation Modeling and Variability Assessment of Delays at Traffic Signals
Publisher: American Society of Civil Engineers
Abstract: This paper presents a microscopic stochastic simulation model developed to emulate the traffic movement at signalized intersections and estimate vehicular delays including the acceleration/deceleration delay. The structure ...
Accuracy of Stopped Delay Measured by Stopped-Vehicle Counts Method
Publisher: American Society of Civil Engineers
Abstract: The stopped delay is a primary factor for measuring the level of service at signalized intersections, and the 1994 Highway Capacity Manual proposed a method for measuring the stopped delay in the field based on direct ...
Two-Way Shear Strength of GFRP-Reinforced Precast Concrete Box Culverts under Vertical Concentrated Loading
Publisher: American Society of Civil Engineers
Abstract: The purpose of this study was to investigate the two-way shear strength of precast concrete box culverts reinforced with glass fiber–reinforced polymer (GFRP) bars. The investigations included testing four full-scale ...
Performance of Composite Structural Insulated Panels after Exposure to Floodwater
Publisher: American Society of Civil Engineers
Abstract: Degradation of structural material because of floodwater is one of the major damaging effects during flooding events. As a result, thousands of homes in coastal states, especially those that are constructed from wood-based ...
Evaluation of In-Situ Pavement Moduli Using High Resolution Tiltmeter
Publisher: American Society of Civil Engineers
Abstract: This study presents a method of estimating the modulus of elasticity of an existing multilayer pavement system. The method is based on the interpretation of a measured deflection basin. The deflections of the existing ...
Numerical Investigation of the Transient Hydrothermal Behavior of a Ferrofluid Flowing Through a Helical Duct in the Presence of Nonuniform Magnetic Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates numerically the time dependent hydrothermal behavior of a ferrofluid (water and 4 vol. % Fe3O4) flowing in a helical channel, which is exposed to a nonuniform transverse magnetic field and its walls ...
