RISOptimum Design of Intermediate Support for Raising Fundamental Frequency of a Beam or Column under Compressive Axial Load
Publisher: American Society of Civil Engineers
Abstract: The optimum design of an additional intermediate support is investigated for raising the fundamental natural frequency of a beam or column subjected to compressive axial loadings. First, the criterion that constitutes the ...
High Performance Adaptive Control of Mechanical Servo System With LuGre Friction Model: Identification and Compensation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: LuGre dynamic friction model has been widely used in servo system for friction compensation, but it increases the difficulty of controller design because its parameters are difficult to be ...
Meta-Atom Molecular Dynamics for Studying Material Property Dependent Deformation Mechanisms of Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: in alloy systems for the limited available interatomic potentials. We adopt the meta-atom method proposed by Wang et al., which unifies MD simulations of both pure metals and alloys in the framework of the embedded atom method (EAM). Owing...
An Experimental Investigation of the Permeability in Porous Chip Formed by Micropost Arrays Based on Microparticle Image Velocimetry and Micromanometer Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurements of velocity and pressure differences for flows in porous chip fabricated with micropost arrays arranged in square pattern were implemented by using micro-particle image velocimetry (micro-PIV) and high precision ...
Fault-Tolerant Control for Electric Ground Vehicles With Independently-Actuated In-Wheel Motors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an in-wheel motor fault diagnosis and fault-tolerant control method for four-wheel independently actuated (4WIA) electric vehicles. The 4WIA electric vehicle is one of the ...
Type Curves Analysis for Asymmetrically Fractured Wells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new constant rate solution for asymmetrically fractured wells was proposed to analyze the effect of fracture asymmetry on type curves. Calculative results showed that for a small wellbore storage coefficient ...
Curvature Theory of Envelope Curve in Two Dimensional Motion and Envelope Surface in Three Dimensional Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The curvature theories for envelope curve of a straight line in planar motion and envelope ruled surface of a plane in spatial motion are systematically presented in differential geometry language. Based on adjoint curve ...
Roles of Drizzle in a One-Dimensional Third-Order Turbulence Closure Model of the Nocturnal Stratus-Topped Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: This study focuses on the effects of drizzle in a one-dimensional third-order turbulence closure model of the nocturnal stratus-topped marine boundary layer. When the simulated drizzle rate is relatively small (maximum ...
Complete Bandgap in Three Dimensional Holey Phononic Crystals With Resonators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the bandgap properties of threedimensional holey phononic crystals with resonators are investigated by using the finite element method. The resonators are periodically arranged cubic lumps in the cubic holes ...
Phase Space Representation and Characteristics of El Niño–La Niña
Publisher: American Meteorological Society
Abstract: The variability of El Niño?La Niña events was analyzed in a low-dimensional phase space, a concept derived from dynamic system theory. The space?time extended EOFs derived from the observed monthly mean SST field over ...
