Flow noise reduction from superhydrophobic surfaces
(2012)
This work investigates how a highly (super)hydrophobic
surface can be used to reduce turbulence-generated drag and
noise on a towed streamer cable. The work is done by analyzing
full-scale drag and flow noise measurements ...
Mechanical Properties of Smokeless Composite Rocket Propellants Based on Prilled Ammonium Dinitramide
(2012)
Ammonium dinitramide (ADN) is a high performance solid oxidizer of interest for use in high impulse and smokeless composite rocket propellant formulations. While rocket propellants based on ADN may be both efficient, clean ...
Neutral Polymeric Bonding Agents (NPBA) and Their Use in Smokeless Composite Rocket Propellants Based on HMXGAP- BuNENA
(2012)
Very few efficient bonding agents for use in solid rocket propellants with nitramine filler materials and energetic binder systems are currently available. In this work, we report the synthesis, detailed characterization, ...
Behavior of captive herring exposed to naval sonar transmissions (1.0-1.6 kHz) throughout a yearly cycle
(2012)
Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ...
On the Use of Computational Fluid Dynamics to Investigate Aerosol Dispersion in an Industrial Environment: A Case Study
(2012)
Aerosol dispersion in the area surrounding an existing biological treatment facility is investigated using large-eddy simulation, with the objective to investigate the applicability of computational fluid dynamics to complex ...
Bandwidth optimizations for standards-based publish/subscribe in disadvantaged grids
(2012)
NATO has identified Web services as a key enabler for its network enabled capability. Web services facilitate interoperability, easy integration and use of commercial off-the-shelf components, and while request/response-based ...
A connectionless multicast protocol for MANETs
(2012)
In this paper, the connectionless multicast routing MCOM (Multipoint relay Connectionless Multicast) is introduced for mobile Ad hoc networks. MCOM adapts over a wide ranges of density of group members. It appears as unicast ...
Adapting OLSR for WSNs (iOLSR) Using Locally Increasing Intervals
(2012)
Proactive link state routing protocols, popular within the Mobile Ad hoc NETwork
framework, have not been as successful in wireless sensor networks. This is mainly due to the
extensive energy usage by control traffic ...
Chirped pulses sum frequency generation for deep-UV picosecond pulse shaping
(2012)
We show by experiments and simulations that properly chirped laser pulses enable efficient and broadband sum frequency generation in nonlinear crystals. We achieved high energy, picosecond deep-UV pulses with spectral ...
Deletion of the γ-aminobutyric acid transporter 2 (GAT2 and SLC6A13) gene in mice leads to changes in liver and brain taurine contents
(2012)
The GABA transporters (GAT1, GAT2, GAT3, and BGT1) have mostly been discussed in relation to their potential roles in controlling the action of transmitter GABA in the nervous system. We have generated the first mice lacking ...
