Modeling challenges of advanced thermal imagers
… observer performance for the identification of military vehicles. An information comparison metric was proposed for the comparison of different spectral images. The impact of dead pixels and thermal imager noise on the comparison metric were measured. A human performance model was then developed …

Finite strain behavior of polyurea for a wide range of strain rates
… Those structures can be used for retrofitting of military vehicles and historic buildings, absorbing energy during structural crash. In order to investigate its behavior of hysteresis as well as rate-sensitivity, three different testing systems are used to cover a wide range of strain rates up to …

An investigation of the forces within the tibiae at typical blast loading rates : with different boots
… IEDs are some of the major threats to military vehicles and their occupants (Ramasamy et al., 2011). The lower extremities of the occupants are very prone to injury, mostly caused by underbelly detonation of AVLs or IEDs due to their spatial proximity to the rapidly deforming floor of a …
