RISTime-Frequency Analysis of Nonlinear Systems: The Skeleton Linear Model and the Skeleton Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The joint time-frequency analysis method is adopted to study the nonlinear behavior varying with the instantaneous response for a class of S.D.O.F nonlinear system. A time-frequency masking ...
Stabilization of Heavy Metals in Contaminated River Sediment by Nanozero-Valent Iron/Activated Carbon Composite
Publisher: American Society of Civil Engineers
Abstract: Nanozero-valent iron/activated carbon (nZVI/AC) composite is investigated as a possible stabilization agent for heavy metals in river sediment. Effects of stabilization were tested by leaching tests such as synthetic ...
Experimental Study of Effects of Grooved Tip Clearances on the Flow Field in a Compressor Cascade Passage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation of effects of grooved tip clearances on the flow field of a compressor cascade. The tests were performed in a low-speed large-scale cascade, ...
Identification of Nonlinear Systems Through Time-frequency Filtering Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the previous paper, a class of nonlinear system is mapped to a so-called skeleton linear model (SLM) based on the joint time-frequency analysis method. Behavior of the nonlinear system may ...
Effect of Deoxyribonucleic Acid on the Chloride Diffusion Behavior of Cement Mortar
Publisher: American Society of Civil Engineers
Abstract: Corrosion of reinforcement bar caused by chloride ions diffusion is a crucial durability problem for concrete structures. Deoxyribonucleic acid (DNA) is a new type of corrosion inhibitor. Previous research has concentrated ...
