RISApplication of Tonal Tracking to Ship Acoustic Signature Feature Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A ship’s radiated acoustic signature is known after a range measurement, but it changes from that the longer the ship is in-service. The Ship Signatures Management System (SSMS) provides an ...
Intercomparison of Attenuation Correction Methods for the GPM Dual-Frequency Precipitation Radar
Publisher: American Meteorological Society
Abstract: new attenuation correction method has been developed for the dual-frequency precipitation radar (DPR) on the core satellite of the Global Precipitation Measurement (GPM) mission. The new method is based on Hitschfeld and ...
Rainfall-Induced Changes in Actual Surface Backscattering Cross Sections and Effects on Rain-Rate Estimates by Spaceborne Precipitation Radar
Publisher: American Meteorological Society
Abstract: In this study, the authors used Tropical Rainfall Measuring Mission precipitation radar (TRMM PR) data to investigate changes in the actual (attenuation corrected) surface backscattering cross section (σ0e) due to changes ...
Object Manipulation Using Compliant Fingerpads: Modeling and Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current industrial robots are often required to perform tasks requiring mechanical interactions with their environment. For tasks that require grasping and manipulation of unknown objects, it is ...
Vibration Control of Bridge Towers Using a Lumped Modeling Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A lumped modeling method and a simple robust control design based on this method are proposed in this paper for controlling the multiple vibration modes of a bridge tower structure under ...
Assessment of Waste-Activated-Sludge Pretreatment by Ultrasound and Applicability of Biodegradability Indicators
Publisher: American Society of Civil Engineers
Abstract: Waste-activated sludge (WAS) samples that were generated over a range of solids residence times (SRTs) under controlled operating conditions were employed in bench-scale sonication tests to characterize the impact of ...
Rain/No-Rain Classification Methods for Microwave Radiometer Observations over Land Using Statistical Information for Brightness Temperatures under No-Rain Conditions
Publisher: American Meteorological Society
Abstract: One of the goals of the Global Precipitation Measurement project, the successor to the Tropical Rainfall Measuring Mission (TRMM), is to produce a 3-hourly global rainfall map using several spaceborne microwave radiometers. ...
Nitrogen Oxide Emissions Characteristics of Augmented Turbofan Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exhaust plumes of modern military engines can be rendered visible at low augmentor power operation by the presence of nitrogen dioxide (NO2 ). Visible plumes have also been observed from ...
Modeling and Feedback Structural Acoustics Control of a Flexible Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A lumping method via an inverse modal analysis approach is proposed in this paper for creating a lumped parameter model for a structure with distributed parameters. On the basis of the lumped ...
Advanced Rain/No-Rain Classification Methods for Microwave Radiometer Observations over Land
Publisher: American Meteorological Society
Abstract: Seto et al. developed rain/no-rain classification (RNC) methods over land for the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI). In this study, the methods are modified for application to other microwave radiometers. The previous...
