RISOptimal Synthesis of Mechanisms for Path Generation Using Refined Numerical Representation Based Model and AIS Based Searching Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an optimal synthesis method for path generation of planar mechanisms, in which a new path-description method named refined numerical representation is proposed to define the ...
Analytical and Numerical Investigation of a Steel Module with a Postbuckling Transition Mechanism for Dynamic Dissipation
Publisher: ASCE
Abstract: Sudden extreme loads acting on a marine structure can seriously damage components; thus, a structural module is beneficial for simultaneously load bearing and energy dissipating. However, the low damping characteristic of ...
Experimental Investigations on the Spillway Section Shape of the Breaching Process of Landslide Dams
Publisher: ASCE
Abstract: Excavation of spillways at dam crest is one of the most commonly utilized and effective engineering practices to mitigate the risk of landslide dams. The influence of spillway section shape on the breaching process of ...
Shear Transfer Capacity of Angle Connectors in U-Shaped Composite Girder: Experimental and Numerical Study
Publisher: ASCE
Abstract: This research investigates the shear resistance of steel angle connectors welded to the webs of U-shaped steel–concrete composite girders. First, push-out tests were conducted on the experimental specimens in which the ...
Applicability of Continuous, Stationary, and Discrete Wavelet Transforms in Engineering Signal Processing
Publisher: ASCE
Abstract: Wavelet-based signal processing techniques are widely applied in multiple disciplines. However, few studies consider the applicability of different wavelet transforms in engineering signal processing fields. Based on the ...
Large-Deformation Finite-Element Analysis of Square Foundations in Spatially Variable Sediments
Publisher: ASCE
Abstract: Square foundations often penetrate deeply into seabed sediments so that sufficient bearing capacity is obtained, which inevitably induces large-scale deformation in the surrounding sediments. Most of the previous research ...
Internal Piping Erosion Evaluation of Embankment Dam Considering the Spatial Variability of Soil Properties
Publisher: ASCE
Abstract: Piping erosion is a crucial trigger for dam breaches. However, the effects of inherent spatial variability on seepage properties have not been considered adequately, which could lead to a significant underestimation of the ...
Efficient Multiscale Methods for Optimal In Situ Bioremediation Design
Publisher: American Society of Civil Engineers
Abstract: This paper presents a multiscale derivative method for solving a successive approximation linear quadratic regulator model for optimal in situ bioremediation design. An efficient one-sided forward divided difference numerical ...
Full Multiscale Approach for Optimal Control of In Situ Bioremediation
Publisher: American Society of Civil Engineers
Abstract: Solving field-scale optimal groundwater remediation design problems is a challenge, especially when computationally intensive reactive transport models are needed. In this paper, a full multiscale approach to partial ...
Prediction of Electromigration Failure of Solder Joints and Its Sensitivity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electromigration (EM) in solder joints under high current density has become a critical reliability issue for the future high density microelectronic packaging. This paper presents atomic density ...
