Build a Green-Water Fleet
The Navy needs small, lethal, fast, green-water ships and submarines to take the fight to the enemy in the littorals. The Mark VI patrol boat (top) and this HOSS X-1 concept submarine (designed by and copyright J. Scott ...
Strong scaling for numerical weather prediction at petascale with the atmospheric model NUMA
Numerical weather prediction (NWP) has proven to be computationally challenging due to its inherent multiscale nature. Currently, the highest resolution global NWP models use a horizontal resolution of 9 km. At this ...
Initial Yield Surface of a Unidirectionally Reinforced Composite
This paper shows the calculation of the initial yield surface of a unidirectionally reinforced composite subjected to longitudinal normal, transverse normal, and longitudinal shear loadings. The composite is composed of ...
Marine Condenser Design Using Numerical Optimization
Computer codes for the analysis of marine steam condensers were coupled with a numerical optimization code to provide fully automated design. The resulting programs are excellent design tools for the conceptual design of ...
Dunkerley-Mikhlin Estimates of Gravest Frequency of a Vibrating System
Estimates are made of the smallest nonzero frequency of vibration of undamped linear mechanical systems having lumped and/or distributed mass and permitting rigid body motions. The approximations are smaller than the correct ...
Oscillating Flow about Two and Three-Dimensional Bilge Keels
The paper describes an experimental investigation of the damping provided by bilge keels in an oscillating flow (in a large U-shaped water tunnel). Rectangular and square flat plates were placed adjacent to a solid boundary ...
Finite Fringe Holographic Interferometry Applied to a Right Circular Cone at Angle of Attack
The successful application of holography to the study of three-dimensional flow fields due to phase objects has been reported in the literature. The present report extends this technique to the study of density fields ...
Thermal Mapping, via Liquid Crystals, of the Temperature Field near a Heated Surgical Probe
This paper discusses the use of heat for producing clinical lesions in tissue and presents the design and analysis of a resistively heated surgical probe. The probe surface temperature is accurately maintained and controlled ...
Is Inpatient Volume or Emergency Department Crowding a Greater Driver of Ambulance Diversion?
(Project HOPE—The People-to-People Health Foundation, Inc., 2018)
Inpatient volume has long been believed to be a contributing factor to ambulance diversion, which can lead to delayed treatment and poorer outcomes. We examined the extent to which both daily inpatient and emergency ...
