RISMonotonicity Analysis and Recursive Quadratic Programming in Constrained Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper considers the use of an active set strategy based on monotonicity analysis as an integral part of a recursive quadratic programming (RQP) algorithm for constrained nonlinear optimization. ...
Transients in Gas-Condensate Natural Gas Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liquid condensation in natural gas transmission pipelines commonly occurs due to the thermodynamic and hydrodynamic imperatives. Condensation subjects the gas pipeline to two-phase transport. Neither ...
Monotonicity Analysis and the Reduced Gradient Method in Constrained Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The concept of monotonicity analysis is combined with the reduced gradient technique for design optimization. The combination is based on a strategy for applying monotonicity analysis in specified ...
Interactive Computing in the Application of Monotonicity Analysis to Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of monotonicity analysis in design optimization has been demonstrated in a number of publications in recent years. The purpose of this paper is to indicate the possibility of implementing ...
Wear Mechanisms of Untreated and Gamma Irradiated Ultra-High Molecular Weight Polyethylene for Total Joint Replacements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modification of the surface microstructure of ultra-high molecular weight polyethylene (UHMWPE) is essential for improving the wear resistance of orthopedic implants. A common approach is to ...
Direct Injection of Aluminum–Organic Matter Flocs to Reduce Soil Permeability and Create a Vertical Flow Barrier In Situ
Publisher: ASCE
Abstract: This study presents a novel geotechnical engineering approach that utilizes naturally occurring processes to reduce soil permeability in-situ. This approach is inspired by a soil stratification process (Podzolization), ...
Entropy Generation in Multicomponent Reacting Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comprehensive equation to determine the rate of local entropy generation in multicomponent, reacting, laminar fluid flow involving heat and mass transfer is formulated based on species-average ...
Fatigue of As-Fabricated Open Cell Aluminum Foams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of the combined experimental investigation and digital image correlation (DIC) analysis of the fatigue failure of open cell aluminum foams. Compression–compression ...
Tribological and Nanomechanical Properties of Unmodified and Crosslinked Ultra-High Molecular Weight Polyethylene for Total Joint Replacements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wear of ultra-high molecular weight polyethylene (UHMWPE) continues to be a major obstacle limiting the longevity of total joint replacements. Efforts to solve the wear problem in UHMWPE have ...
Vibration Monitoring and Damage Quantification of Faulty Ball Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: More often than not, the rolling element bearings in rotating machinery are the mechanical components that are first prone to premature failure. Early warning of an impending bearing failure ...
