A Navier-Stokes analysis of the stall flutter characteristics of the Buffum cascade
(ASME, 2000)
Numerical stall flutter prediction methods are much needed, as modern jet engines require blade designs close to the stability boundaries of the performance map. A Quasi-3D Navier–Stokes code is used to analyze the flow ...
Characterizing the stability of carbon nanotube-enhanced water as a phase change material for thermal management systems
(ASME, 2011)
Carbon nanotube (CNT) suspensions have shown promise as a heat transfer nanofluid due to their relatively high thermal conductivity and ability to remain in stable suspension for long durations. To assess their potential ...
Procurement fraud in the U.S. Department of Defense: implications for contracting processes and internal controls
(Emerald, 2016)
Purpose - This paper aims to explore selected real-world procurement fraud incidents in the US
Department of Defense (DoD) and the implications of these incidents to the DoD’s contracting
processes and internal ...
Multi-physics energy approach and demonstration facility
(ASME, 2015)
A methodology to investigate the generation, transport and storage of energy based on a multi-physics approach, tied to the end use application, is presented. Often little or no consideration is given to the end use or ...
Effect of friction stir welding on hydrogen content of ISO 3183 X80M steel
(Elsevier, 2016)
The influence of Friction Stir Welding (FSW) on hydrogen content of ISO 3183 X80M high strength
steel was evaluated for several welding conditions, including dry and underwater environments. The diffusible and non-diffusible ...
Acceleration of the implicit-explicit non-hydrostatic unified model of the atmosphere (NUMA) on Manycore processors
(Sage, 2017)
We present the acceleration of an IMplicit-EXplicit (IMEX) non-hydrostatic atmospheric model on
manycore processors
such as GPUs and Intel’s MIC architecture. IMEX time integration methods sidestep the constraint
imposed ...
A residual-based shock capturing scheme for the continuous/discontinuous spectral element solution of the 2D shallow water equations
(2016-07-11)
The high-order numerical solution of the non-linear shallow water equations is susceptible to Gibbs oscillations in the proximity of strong gradients. In this paper, we tackle this issue by presenting a shock capturing ...
Autonomous measurement of space shuttle payload bay acoustics during launch
(Office of Naval Research, 1987)
A method of recording and analyzing the acoustic characteristics of the Space Transportation
System (STS) cargo bay has been developed . The experiment is integrated within a NASA
Get-Away-Special (GAS) canister. The ...
The transforming nature of metaphors in group development: a study in group theory
(Tavistock Institute of Human Relations, 1988)
It is proposed in this paper that members' creation of metaphors facilitates further expression and
development of the group. Few methodologies for group inquiry help us in understanding the tacit
awareness (Polanyi, ...
Reacting to crisis: the costs of first response by the United States Navy
(DeGruyter, 2017)
The U.S. Navy has declared humanitarian assistance and disaster response (HADR) operations as a
core mission in support of the U.S. national security strategy. However little work has been done to illustrate which vessels ...
