RISDiscussion of “Survey of Practice to Determine Strength of In Situ Concrete from Core Tests” by John M. Hanson
Publisher: American Society of Civil Engineers
Discussion of “<i>Free Vibration Behavior of Prestressed Beams</i>” by K. Kanaka Raju and G. Venkateswara Rao (February, 1986, Vol. 112, No. 2)
Publisher: American Society of Civil Engineers
Turbine Engine Icing Spray Bar Design Issues
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Techniques have been developed at the Engine Test Facility (ETF) of the Arnold Engineering Development Center (AEDC) to simulate flight through atmospheric icing conditions of supercooled liquid ...
A Study of Boundary-Layer Pressure Adjustments
Publisher: American Meteorological Society
Abstract: An analytical two-layer approximation of atmospheric flow is developed to study boundary-layer production of vertical motion. The model consists of a boundary layer topped by a free-flow layer. Both layers am time-dependent ...
Seismic Forces in Spherical Domes: Membrane Solution
Publisher: American Society of Civil Engineers
Abstract: With the increase in dome construction that has accompanied the advent of economical balloon-forming techniques, many engineers are now involved in thin-shell dome design. For simple spherical domes of nominal size that ...
A Lower-Tropospheric Thermodynamic Climatology for March through September: Some Implications for Thunderstorm Forecasting
Publisher: American Meteorological Society
Abstract: A thermodynamic climatology was constructed to investigate source regions of low-level moist airmasses and lower mid-tropospheric dry airmasses that contribute to the production of convective instability, and thunder-storms, ...
Peninsular Florida Tornado Outbreaks
Publisher: American Meteorological Society
Abstract: An analysis of statistics for 1448 tornadoes documented by the National Severe Storms Forecast Center from 1950 through 1994 at, or south of, 30° latitude in Florida was completed to determine the definition of a peninsular ...
A Symmetric Multichamber Hydraulic Cylinder With Variable Piston Area: An Approach to Compact and Efficient Electrohydrostatic Actuation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an approach for designing symmetric (effective cylinder area during extension is the same as that during retraction) multichamber cylinders with discretely variable piston area. The design methodology ...
