RISMulti-Channel Multi-Scale and Graph Relationship Meta Learning Intelligent Detection Method in Aircraft Engine Fault Maintenance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Due to the complexity of the operating environment and the diversity of components, fault maintenance and detection of aircraft engines have always been a huge challenge. To improve the reliability and maintenance ...
Managing the Embodied Carbon of Precast Concrete Columns
Publisher: American Society of Civil Engineers
Abstract: With the rising recognition of global climate change, the term
Investigation of the Diurnal Variation of Marine Boundary Layer Cloud Microphysical Properties at the Azores
Publisher: American Meteorological Society
Abstract: new method has been developed to retrieve the nighttime marine boundary layer (MBL) cloud microphysical properties, which provides a complete 19-month dataset to investigate the diurnal variation of MBL cloud microphysical ...
A Climatology of Marine Boundary Layer Cloud and Drizzle Properties derived from Ground-based Observations over the Azores
Publisher: American Meteorological Society
Abstract: In this study, more than four years of ground-based observations and retrievals were collected and analyzed to investigate the seasonal and diurnal variations of single-layered MBL (with three subsets: non-drizzling, virga ...
Study on the Four-Quadrant Homologous Characteristic and Two-Phase Flow Head Degradation of a Reactor Coolant Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the four-quadrant homologous characteristic and analyzes the gas–liquid two-phase flow head degradation of ACP100 reactor coolant pump. The theoretical basis and the operating conditions of the pump's ...
Comparison Analysis on the Hydraulic Performance and Flow Characteristics on a Reactor Coolant Pump Under Rated Operating Condition Between Lead–Bismuth Eutectic and Water Mediums
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Advanced Generation IV nuclear reactors aim to enhance the sustainability, passive safety, reliability, and economic efficiency of reactor operations. Within that, the reactor coolant pump is a critical component in the ...
Calibration of Mesoscopic Parameters for Lunar Soil Using a Machine Learning–Based Discrete Element Method
Publisher: American Society of Civil Engineers
Abstract: AbstractAccurate calibration of the mesoscopic parameters of lunar soil is essential for effectively
simulating and analyzing lunar engineering problems using the discrete element method
(DEM). However, conventional ...
An Unsupervised Acoustic Denoising Model for Water Leakage Detection
Publisher: American Society of Civil Engineers
Abstract: AbstractThe global issue of water loss due to leakage in water distribution networks (WDNs)
is considerable. Acoustic methods are preferred for leak detection because they are
noninvasive, efficient, and cost-effective. ...
Effect of Trailing Edge Modification of a Mixed Flow Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern pumps are designed to guarantee a sufficiently large operating range or to satisfy the performance requirements relative to more than one operating point. This study applies trailingedge (TE) modification method ...
Transient Characteristics of a Closed Loop Pipe System During Pump Stopping Periods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to study the transient characteristics of a closedloop pipe system with room temperature water, experiments were carried out based on different pump stopping periods from rate rotational speed to zero. Various ...
