RISA Grouped Threshold Approach for Scene Identification in AVHRR Imagery
Publisher: American Meteorological Society
Abstract: The authors propose a grouped threshold method for scene identification in Advanced Very High Resolution Radiometer imagery that may contain clouds, fire, smoke, or snow. The philosophy of the approach is to build modules ...
Daytime Multilayered Cloud Detection Using Multispectral Imager Data
Publisher: American Meteorological Society
Abstract: This study reports on recent progress toward the daytime detection of multilayered clouds in satellite multispectral data, specifically for the case of optically thin cirrus overlying lower-level water clouds. The technique ...
Biaxial Loading of Offshore Monopiles: Numerical Modeling
Publisher: American Society of Civil Engineers
Abstract: In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and ...
Small Stone-Column Groups: Mechanisms of Deformation at Serviceability Limit State
Publisher: American Society of Civil Engineers
Abstract: Stone columns are a popular form of ground improvement that can be applied to a variety of foundation solutions involving soft soil deposits. Many design methods are based on an assumption that columns with a length-to-diameter ...
Pile Group Settlement Estimation: Suitability of Nonlinear Interaction Factors
Publisher: American Society of Civil Engineers
Abstract: In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ...
Computational Modeling and Analysis of Multiple Steady States in Vapor Compression Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a well-posed two-point boundary value problem framework for computing, via continuation, the steady states of interconnected vapor compression systems. We illustrate the ...
Design and Implementation of a Prototype Data System for Earth Radiation Budget, Cloud, Aerosol, and Chemistry Data
Publisher: American Meteorological Society
Abstract: The Earth Observing System (EOS) will collect data from a large number of satellite-borne instruments, beginning later in this decade. To make data accessible to the scientific community, NASA will build an EOS Data and ...
Cirrus Cloud Retrieval Using Infrared Sounding Data: Multilevel Cloud Errors
Publisher: American Meteorological Society
Abstract: In this study we perform an error analysis for cloud-top pressure retrieval using the High-Resolution Infrared Radiometric Sounder (HIRS/2) 15-µm CO2 channels for the two-layer case of transmissive cirrus overlying an ...
Untitled
Publisher: American Society of Civil Engineers
Abstract: Two implementations of the Pareto archived dynamically dimensioned search (PADDS) algorithm using different selection metrics are applied to 12 water distribution network (WDN) design benchmark problems from the literature. ...
Applicability of CPT Capacity Prediction Methods to Driven Cast-In-Situ Piles in Granular Soil
Publisher: ASCE
Abstract: Databases used in developing cone penetration test (CPT)-based design methods for driven piles have been dominated by data for the preformed variant, with the driven cast-in-situ (DCIS) pile category poorly represented. A ...
