RISEvolution Characteristics Analysis of Supersonic Inlet Buzz with High-Order Dynamic Mode Decomposition Method
Publisher: ASCE
Abstract: The buzz evolution process of an axisymmetric supersonic inlet was investigated numerically and analyzed using the high-order dynamic mode decomposition (HODMD) method. Driven by an increasing back-pressure, the flow field ...
Probabilistic Data Association-Feedback Particle Filter for Multiple Target Tracking Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with the problem of tracking single or multiple targets with multiple nontarget-specific observations (measurements). For such filtering problems with data association uncertainty, a novel feedback ...
Parametric Study of Impeller Ring Tongue of Regenerative Hydrogen Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The clearance between impeller disk and the adjacent casing of the regenerative hydrogen pump constitutes a pair of important dynamic seals that affect pump performance and disk force. In this work, a regenerative hydrogen ...

Enhancement of the Aging Resistance Performance of Asphalt Binder Using Activated Coal Gangue Waste and Determination of the Influence Mechanism Based on Interfacial Interaction Ability
Publisher: American Society of Civil Engineers
Abstract: AbstractThis study conducted thermal activation approach to modify coal gangue (CG) waste
from 450°C to 900°C and applied it to enhance aging resistance performance of asphalt
binder. The surface morphology, mineral ...
Model Predictive Control of a Parafoil System via the Koopman Operator
Publisher: American Society of Civil Engineers
Abstract: AbstractExisting predictive control of parafoils is based on the local linearization of the
dynamic system around its equilibrium state, which fails to capture global nonlinear
characteristics. To address this limitation, ...
Nanoscale Miscibility Pressure Prediction Model With Critical Property Shifts and Adsorption Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Carbon dioxide flooding delivers dual benefits by increasing oil recovery and storing greenhouse gases, and shows strong application potential in unconventional reservoirs. These reservoirs contain abundant ...
g-C3N4/TiO2 Photocatalyst and Its Performance of NO Degradation in Emulsified Asphalt
Publisher: American Society of Civil Engineers
Abstract: This study prepared one g-C3N4/TiO2 composite photocatalyst by calcinating a mixture of melamine and nano TiO2, and then mixed it with asphalts to photodegrade the NO produced by automobile exhaust. The melamine and TiO2 ...
Progressive Collapse Resistance of Posttensioned Concrete Beam-Column Subassemblages with Unbonded Posttensioning Strands
Publisher: American Society of Civil Engineers
Abstract: In this study, the behavior of posttensioned reinforced concrete (PC) beam-column subassemblages subjected to the loss of a middle column is investigated experimentally. The influence of unbonded posttensioning strands ...
Bending Fatigue Test and Interlayer Pavement Models for Beams of Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: The fatigue life of composite beam samples were measured by flexural fatigue test under different bonding oil contents, temperatures, and loads. The measurement was conducted to study the influence of interlayer contact ...
