RISManaging Nitrate Problems for Domestic Wells in Irrigated Alluvial Aquifers
Publisher: American Society of Civil Engineers
Abstract: Many irrigated areas in the United States and abroad overlie unconfined aquifers. The soils are coarse textured with low water-holding capacity, and irrigation water is frequently necessary for crop growth. Many of these ...
Zeroth-Order Shear Deformation Theory for Laminated Composite Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a zeroth-order shear deformation theory has been derived for static and dynamic analysis of laminated composite plates. The responses obtained by the theory for symmetric and ...
DESCRIPTION AND OPERATION OF THE T-SONDE, A Low-Level Air Temperature Measuring Device
Publisher: American Meteorological Society
Abstract: A system to obtain the detailed temperature profiles from the ground surface to heights of 1500?2000 m. has been developed. This economical system employs modified radiosondes and less complex receiving equipment than used ...
Risk-Based Prioritization of Terrorist Threat Mitigation Measures on Bridges
Publisher: American Society of Civil Engineers
Abstract: This paper describes a risk-based methodology developed to facilitate prioritization of terrorist threat mitigation strategies on individual bridges. Numerous risk-based methods have been used for prioritization among a ...
A METHOD OF INTEGRATING A RADIOMETER OUTPUT FOR CLIMATOLOGICAL STUDIES
Publisher: American Meteorological Society
Abstract: A method of integrating a radiometer output using operational amplifiers to give 60-min. readout of solar and terrestrial radiation in gm.-cal. cm.?2 hr.?1 is described. The system also includes a compensation circuit for ...
Active Damping of Nonlinear Vibrations of Functionally Graded Laminated Composite Plates using Vertically/Obliquely Reinforced 1-3 Piezoelectric Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with a study on the active constrained layer damping (ACLD) of geometrically nonlinear vibrations of functionally graded (FG) laminated composite plates. The constraining layer ...
Effect of Carbon Nanotube Waviness on the Load Transfer Characteristics of Short Fuzzy Fiber-Reinforced Composite
Publisher: American Society of Civil Engineers
Abstract: The effect of waviness of carbon nanotubes (CNTs) on the load transfer characteristics of the short fuzzy fiber-reinforced composite (SFFRC) has been studied, considering the wavy CNTs to be coplanar with either of the two ...
Exact Solutions for the Functionally Graded Plates Integrated With a Layer of Piezoelectric Fiber-Reinforced Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the derivation of exact solutions for the static analysis of functionally graded (FG) plates integrated with a layer of piezoelectric fiber reinforced composite (PFRC) ...
Effective Properties of Carbon Nanotube and Piezoelectric Fiber Reinforced Hybrid Smart Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We propose a new hybrid piezoelectric composite comprised of armchair single-walled carbon nanotubes and piezoelectric fibers as reinforcements embedded in a conventional polymer matrix. Effective ...
Rapid Restoration of War-Damaged 19th Century Lifeline Bridge
Publisher: American Society of Civil Engineers
Abstract: The 29-span highway bridge across the Sava River at Brcko, Bosnia, dates to 1894 and suffered the destruction of four deck trusses during the recent war. Following the deployment of U.S. peace keepers, the swift reopening ...
