Geolocation and Stereo Height estimation Using TerraSAR-X Spotlight Image Data
(2011)
We have studied the geographic position of several high-resolution spotlight TSX images by investigating the location of deployed radar corner reflectors. Results show that the geolocation accuracy is better than the ...
Enantioselectivity, swelling and stability of 4-hydroxyprolinol containing acrylic polymer beads in the asymmetric reduction of ketones
(2011)
A new 4-hydroxy-α,α-diphenyl-l-prolinol containing polymethacrylate, prepared without chromatography by a large scale adaptable synthesis, has been evaluated as a catalyst in the asymmetric reduction of 1-arylethanones. ...
A Framework for Authentication in NBD Tactical ad hoc networks
(2011)
Network-based defense (NBD) and the all-IP network make authentication ever more important. However, a generally accepted and comprehensive authentication suite is lacking. This work is a step toward filling the gap. The ...
Severe gunshot injuries in a porcine model: impact on central markers of innate immunity
(2011)
Background
The mechanisms behind lipopolysaccharide (LPS) tolerance remain obscure. LPS signals through Toll-like receptor 4 (TLR4) and severe trauma/haemorrhage may influence binding and signalling through this receptor, ...
High pulse energy and symmetrical far field from an optical parametric oscillator in the red spectral range
(2011)
Red pulses with >30 mJ energy and <0.6 nm bandwidth have been demonstrated using a type 2 phase matched optical parametric oscillator pumped at 532 nm. A symmetrical signal beam with beam diameter-divergence product of ~3 ...
Effect of Tonsillar Herniation on Cyclic CSF Flow Studied with Computational Flow Analysis
(2011)
BACKGROUND AND PURPOSE: The Chiari I malformation, characterized by tonsils extending below the foramen magnum, has increased CSF velocities compared with those in healthy subjects. Measuring the effect of tonsillar ...
Comparison of two methods for automatic range alignment in ISAR imaging
(2011)
A maximum likelihood algorithm for translational motion estimation (TME) in ISAR imaging is described and compared with prominent point processing (PPP). It is suggested that the kurtosis (fourth order central moment) of ...
Challenges in Seafloor Imaging and Mapping With Synthetic Aperture Sonar
(2011)
Synthetic aperture sonar (SAS) is emerging as an imaging technology that can provide centimeter resolution over hundreds-of-meter range on the seafloor. Although the principle of SAS has been known for more than 30 years, ...
Exploring Network Organization in Military Contexts: Effects of Flatter Structure and More Decentralized Processes
(2011)
Changes in the tasks and responsibilities of military organizations in recent decades have prompted new organizational solutions collectively known as network organization. Network organization includes changes to central ...
Real-time georeferencing for an airborne hyperspectral imaging system
(2011)
The paper describes the georeferencing part of an airborne hyperspectral imaging system based on pushbroom scanning. Using ray-tracing methods from computer graphics and a highly efficient representation of the digital ...
