Thermal neutron analysis for improvised explosive device detection
… dissertation, the design of a system to detect improvised explosive devices is considered. The technique utilized is thermal neutron analysis. In this method, thermal neutrons are used to interrogate a volume for the presence of nitrogen, which is used as an indicator of explosive, given its …

Improvised explosive device crater repair for enduring route remediation
… due to the ease of emplacement of additional improvised explosive devices (IEDs). In addition to the threat of IED placement, the threat from exposure of the repair teams to enemy attack during placement and curing was substantial. In order to address these problems, this project investigated …

Development of Total Vaporization Solid Phase Microextraction and Its Application to Explosives and Automotive Racing
Pipe bombs are a common form of improvised explosive device, due in part to their ease of construction. Despite their simplistic nature, the lethality of pipe bombs should not be dismissed. Due to the risk of harm and their commonality, research into the pipe bomb deflagration process and …

Improving situational awareness in the counter-IED fight with the utilization of unmanned sensor systems
… situational awareness (SA) in the counter-improvised explosive device (C-IED) fight. An appropriate systems engineering design process was used to develop such a framework, as the completion of the first two phases - problem definition and solution design - provides a basis for analysis of …

Organic lateral heterojunction devices for vapor-phase chemical detection
… against potential attacks. On the battlefields, improvised explosive devices (IEDs) have resulted in 54% of all coalition deaths in Iraq and 59% in Afghanistan. The U.S. military has responded with an intensive program of technology development, spending $12.4 billion over the past three years on …

The response of a structural target to oblique fragment and blast loading
An improvised explosive device (IED) can be defined as a homemade bomb which is used to target humans and structures [1]. IEDs commonly have dual damaging effects, a high-pressure blast wave that propagates outwards from the point of detonation as well as blast induced fragments. The blast induced …

Lower Extremity Biomechanical Response of Female and Male Post-Mortem Human Surrogates to High-Rate Vertical Loading During Simulated Under-Body Blast Events
During an under-body blast (UBB) event, an improvised explosive device (IED) delivers a high-energy blast beneath a military vehicle, exposing mounted Warfighters to considerable risk of severe lower extremity injuries. Loftis and Gillich (2014) determined that the lower leg and ankle region is the …

Detecting Threats from Constituent Parts: A Fuzzy Signal Detection Theory Analysis of Individual Differences
… and non-signal properties. For instance, an improvised explosive device (IED) poses little threat when missing key elements of its assembly (a stimulus of low, but not zero, signal strength) whereas the threat is greater when all elements necessary to ignite the device are present (a stimulus …

An innovative protective jacket for structures subject to blast loads: A comprehensive experimental and simulation study
… mitigation, where a vehicle-borne bomb or an improvised explosive device can readily cause an under-designed structure with insufficient redundancy to undergo progressive collapse due to the removal of its first-floor columns. An especially pressing research need is the consideration of …

The Response of a Structural Target to an Explosive Charge Incorporating Foreign Objects: A Numerical Study
… the effect of incorporating foreign objects into explosive and its subsequent influence on the response of a target structure. The explosive, the container and the ball bearings were simplified representation of the key components of an improvised explosive device (IED). The numerical study was …
