On Explosive Time Series
… expectations framework using a bivariate coexplosive vector autoregression as in Nielsen (2010). Firstly, we apply a co-explosive vector autoregression to model whether the WTI crude oil price run-up of 2007-2008 can be attributed to the existence of a bubble as well as whether the WTI crude …

Detection of explosive materials
Explosive materials are increasingly being exploited by criminal organisations,with harmful, devastating and destructive effects on targeted societies; highlighting the demand for sensitive, reliable and quick explosive detection methods that can be used in a range of environments. Immunoassays are …

Explosive remnants of war: a case study of explosive ordnance disposal in Laos, 1974-2013
… the subsequent Protocol V to the 1980 Treaty on Explosive Remnants of War (ERW) and the 2008 Convention on Cluster Munitions (CMC). In nine years from 1964-1973 the U.S.A. dropped 260 million cluster bomb submunitions on Laos. It is estimated that 30 percent of the cluster munitions failed to …

Dynamics of deep-submarine explosive eruptions
This thesis explores the dynamics of explosive volcanic eruption columns in the deep-ocean. Motivated by the observations of pyroclastic deposits on the sea floor at depths of up to 4 km, we investigate the initial mixing of erupted hot fragmented magma with the ambient seawater and explore the …

Explosive Safety with Regards to Electrostatic Discharge
… event may be significant enough to initiate an explosive material. Explosives materials are materials that many people might recognize as susceptible to initiation due to mechanical insults. Plastic and foam materials are often used to protect explosives. Unfortunately, often many of these …

Compressive Behavior of Simulated Explosive-Filled Composites
… focused on examining the interaction between explosive crystals and the substrate of interest. However, this neglects the effects of the binder material in compounds such as Composition C-4. These types of explosives are actually agglomerates comprised of the energetic particulate material and …

Shock wave interactions at explosive/metallic interfaces
<p>"Metallic tubes filled with C-4 high-explosive and constructed of either aluminum or copper were tested during this study of high strain rate effects within thin metal cylinders performed as an adjunct to helical flux-compression generator research at the University of Missouri-Rolla. This study …

Near-infrared emission spectroscopy of explosive breakout
… in the near infrared spectrum of various high explosives. Explosives tested include RDX, Composition B, HMX, and PETN, along with RP1 and RP80 detonators in air and nitrogen environments. The first 20 microseconds after detonation were examined using a combination of a rotating filter disk and …

Explosive property of aluminum powder liquid oxygen mixture
<p>The purpose of this investigation was to determine the optimum conditions for explosion of a mixture of aluminum powder and liquid oxygen when fired without the use of a fixed detonator.</p>

Thermal neutron analysis for improvised explosive device detection
… 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 unusual high …

Improvised explosive device crater repair for enduring route remediation
… 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 rapid …

Explosive initiation of tungsten based reactive materials in air
… of reactive materials (RM’s) initiated by a high explosive detonation. High speed pressure, shadowgraph imaging, pyrometry and spectroscopy diagnostics were developed and used concurrently for tests conducted in these facilities. Well known thermite, intermetallic and reactive metal compounds were …

Explosive Volcanism in the Kenyan Rift: A Tephrostratigraphic Perspective
… Lake Naivasha reveals three previously unknown explosive events (7350-4817 cal yrs BP) from the nearby volcanic system of Longonot. The combined major, minor and trace element datasets presented here are one the first of its kind and will prove valuable to future work in the region aiming to …

Explosive energy yield analysis of World Trade Center crash
… conducted to rule out the possibility of other explosive elements (i.e. a bomb) on board. The amount of fuel ignited and the corresponding energy yielded by the fireball was estimated by studying videotapes of the crashes. The calculated volume of fuel vapor, which is consumed to form the …
