RISPrecision and Accuracy of Sunphotometry—A Response
Publisher: American Meteorological Society
Abstract: Reassessment of sun photometer data generally gives no indication of detector sensitivity changes but attention should be given to turbidity variations and sufficient airmass range.
Spectral Skylight and Solar Radiance Measurements in the Caribbean: Maritime Aerosols and Sahara Dust
Publisher: American Meteorological Society
Abstract: Measurements of solar radiation from ?0.45 to 1.6 ?m during May 1969 at St. Croix (Virgin Islands) in the western tropical Atlantic showed a minimum of aerosol optical thickness near 0.6 ?m, which is probably typical of a ...
Shear Strength of Chemically Based Self-Consolidating Concrete Beams: Fracture Mechanics Approach versus Modified Compression Field Theory
Publisher: American Society of Civil Engineers
Abstract: An experimental investigation was conducted to study the shear strength of full-scale beams constructed with both chemically based self-consolidating concrete (SCC) and conventional concrete (CC). This experimental program ...
SCATTERING FUNCTION AND POLARIZATION OF SKYLIGHT IN THE ULTRAVIOLET TO THE NEAR INFRARED REGION, WITH HAZE OF SCATTERING TYPE 2
Publisher: American Meteorological Society
Abstract: Measurements of the scattering-phase function and of the polarization of skylight in rather strong haze of turbidity type 2, in the wavelength range from 0.38 to 1.76 ?, have been made at Mainz, Germany. As already found ...
Nonlinear Decentralized Control of a Flexible Cable-stayed Beam Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A decentralized controller that suppresses the vibrations of a flexible cable-stayed beam structure induced by an external random disturbance is presented. The controller is designed based on a ...
Monitoring and Mitigation of Movements Affecting Foundations on Expansive Soils in Colorado
Publisher: American Society of Civil Engineers
Abstract: Foundation movements attributable to expansive clays and claystones continue to challenge the geotechnical and structural-engineering communities. This study summarizes information and data, collected over the past 25 ...
Atomic-Scale Three-Dimensional Phononic Crystals With a Very Low Thermal Conductivity to Design Crystalline Thermoelectric Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Superlattices with thermal-insulating behaviors have been studied to design thermoelectric materials but affect heat transfer in only one main direction and often show many cracks and dislocations ...
The Intensity of the Twilight and Upper Atmospheric Dust
Publisher: American Meteorological Society
Abstract: Absolute intensities have been measured over the whole twilight at an angle of elevation of 20° in an attempt to derive quantitative data on dust concentrations in the mesosphere. With the aid of model computations based ...
Behavior of a 3-Span Continuous Bridge Before and After Continuity Joint Replacement Using Ultra-High-Performance Concrete
Publisher: ASCE
Abstract: One method of bridge construction consists of simply supported precast, prestressed concrete girders made continuous for live load through individual continuity joints connecting the two girder ends from adjacent spans. ...
