RISThrust Rebalance to Extend Engine Time On-Wing With Consideration of Engine Degradation and Creep Life Consumption
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Over the years, airlines have consistently attempted to lower their operational costs and improve aircraft availability by applying various technologies. Engine maintenance expenses are one of the most substantial costs ...
Analysis of Traffic Accident Reconstruction Uncertainty
Publisher: American Society of Civil Engineers
Abstract: There are many uncertain factors in road traffic accident. It is necessary to consider the uncertainty influence of these factors by random theory to improve the analysis veracity. In order to improve the precision and ...
Orienting Ground Motion Inputs to Achieve Maximum Seismic Displacement Demands on Electricity Transmission Towers in Near-Fault Regions
Publisher: American Society of Civil Engineers
Abstract: This investigation was focused on developing an approximate approach for properly orienting ground motion inputs to achieve the maximum displacement demands on electricity transmission towers in the near-fault regions. The ...
Strongly Coupled Assimilation of a Hypothetical Ocean Current Observing Network within a Regional Ocean–Atmosphere Coupled Model: An OSSE Case Study of Typhoon Hato
Publisher: American Meteorological Society
Effect of Shaft Diameter on the Hydrodynamic Torque of Butterfly Valve Disk
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, computational fluid dynamics (cfd) software and detached eddy simulation turbulence model were used to simulate butterfly valves with different designs. The effects of shaft diameters on the value and the ...
AntiWear Effect of Mo and W Nanoparticles as Additives for Multialkylated Cyclopentanes Oil in Vacuum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work examined friction-reducing and antiwear behaviors of multialkylated cyclopentanes (MACs) oil with Mo and W nanoparticles as additives under vacuum condition (∼10−4 Pa). The tribological evaluation was conducted ...
Investigating Time-Scale Effects on Reference Evapotranspiration from Epan Data in North China
Publisher: American Meteorological Society
Abstract: Reference evapotranspiration (ETo) and pan evaporation (Epan) are key parameters in hydrological and meteorological studies. The authors? objectives were to evaluate the ratio of ETo to Epan (kp) at daily and monthly scales ...
A Dynamic Reliability Centered Maintenance Analysis Method for Natural Gas Compressor Station Based on Diagnostic and Prognostic Technology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The availability requirement of natural gas compressors is high. Thus, current maintenance architecture, combined periodical maintenance and simple condition based maintenance, should be improved. In this paper, a new ...
Random Seismic Response and Dynamic Fuzzy Reliability Analysis of Bedding Rock Slopes Based on Pseudoexcitation Method
Publisher: American Society of Civil Engineers
Abstract: Seismic ground motion is a dynamic random process, and it has obvious random uncertainty. The traditional reliability analysis of bedding rock slopes under earthquake excitation is usually based on pseudostatic method and ...
Convolutional Neural Network Denoising Auto-Encoders for Intelligent Aircraft Engine Gas Path Health Signal Noise Filtering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Removing noise from health signals is critical in gas path diagnostics of aircraft engines. An efficient noise filtering/denoising method should remove noise without using future data points, preserve important changes, ...
