Landmine detection with a standoff acoustic/laser technique
Landmines and mine-like traps are effective weapons that are difficult to detect and discriminate from a safe distance. The ability to detect landmines in their host environment at a distance and to discriminate them from other objects would be valuable for countering the landmine threat. This …

Radar Imaging Applications for Mining and Landmine Detection
… walls. Detecting and characterizing UXO and landmines from a safe distance can enable de-mining. Migration was used to improve GPR imaging for unmanned aerial vehicle (UAV) data acquisitions. Existing algorithms were adapted for UAV flight irregularities and surface topography, and a new …

Landmine classification using possibilistic K-nearest neighbors with wideband electromagnetic induction data
… target classes or a non-target class. For some landmine detection systems, it could be necessary or helpful to discriminate between the several classes of targets, so that they can be analyzed and processed according to their specific properties. For example, it might be of importance to …

Examining the effectiveness of international landmine regimes. The interplay between design and implementation.
… developed to prohibit or restrict the use of landmines. However, reflecting a gap in current academic research, there is a lack of knowledge of their effectiveness in supporting the humanitarian goals that underpin both treaties. In order to address gaps in the existing literature, this thesis …

Investigation of factors affecting surrogate limb measurements in the testing of landmine protected vehicles
Landmine protected vehicles (LPVs) are designed to minimise the risk of injury to occupants. In order to quantify this risk, human surrogate measurement devices (HSMDs) are placed in the vehicle to record data which is then related to risk of injury using injury criteria that have been defined in …

Part of the Solution: Exploring Armed Non-State Actor Commitment to and Compliance with an Anti-Personnel Landmine Ban
… Ottawa Treaty regime, renounced anti-personnel landmines through a formal and monitored mechanism created by the international non-governmental organization Geneva Call. Why have some armed non-state actors committed themselves to and complied with this total anti-personnel landmine ban that …

Landmine removal : technology review and design proposal as pertaining to humanitarian demining with a focus on locomotion across soft terrain
A study into the field of humanitarian landmine removal was conducted; with significant attention devoted to an in depth review of existing removal technologies, as well as alternative detection methods. A design proposal was also presented in addition to the technology review. The design is for an …

Physically Motivated Feature Development for Machine Learning Applications
… disaggregation, brain cancer prognosis, and landmine detection with seismo-acoustic vibrometry (SAVi) sensors. For event-based energy disaggregation, or the automated process of extracting component specific energy data from a building's aggregate power signal, we develop low dimensional …

Stress Wave Propagation In A ‘Simplified Surrogate Tibia’ Subjected To Blast Loading
Landmines are a continuous and serious threat to mankind, resulting in thousands of casualties globally each year. Casualties have risen due to the proliferation of improvised explosive devices (IEDs), cluster munition remnants, and other explosive remnants of war. In these terrible occurrences, …

Nonlinear Acoustics and an Inverse Scattering Problem
… a secondary part will look at the problem of landmine detection and how to improve the target detection rates. The work on nonlinear acoustics emerged as a desire to model the behaviour of the sonic booms formed by supersonic aircraft in the atmosphere to see what environmental impact they …

The effect of bend radius on the impulse transfer characteristics of V-hulls
… scaling was based on the dimensions of the TM-57 landmine and the Casspir APC MK II. In the numerical model, the optimum element length for the air mesh was obtained by performing a mesh convergence study on the Arbitrary Lagrangian-Eulerian (ALE) mesh, and validated using the impulse values …

Analysing the influence of TNT on Southern African trees grass and shrubs using in-situ hyperspectral data
Landmines pose a significant risk to the health and livelihood of millions of people in war-torn countries. From a humanitarian point of view, these hidden dangers must be detected and removed. Several detection methods exist, including ground-penetrating radar, sniffer dogs and rats. It is a …

Development of the "Discretized Dynamic Expanding Zones with Memory" Autonomous Mobility Algorithm for the Nemesis Tracked Vehicle Platform
… sensor suite used for detecting and neutralizing landmines. Because the detection process requires the vehicle to travel at speeds less than 0.5 km/h, teleoperation is a tedious process. The added autonomous capabilities of waypoint navigation and obstacle avoidance could greatly reduce operator …

Naturalistic Study Examining the Data/Frame Model of Sensemaking by Assessing Experts in Complex, Time-Pressured Aviation Domains
… on expert chess players, radiologists and landmine detection personnel suggests a use of cognitive frameworks, alternatively referred to as schemas, templates, scripts, frames and models, to effectively perceive, interpret, understand, recall, and anticipate information. These experts may …

Ultra-Wideband Channel Modeling using Singularity Expansion Method
… of this doctoral research is to improve buried landmine detection as well as breast tumor detection by applying statistical and fuzzy analysis to the backscatter response. Moreover, radar target identification using UWB short pulses stands to gain tremendously from this research.

The response of quadrangular plates to buried encased charges
… encased charges with a view of understanding landmine effects on simple structures. Different loading scenarios were carried out for comparison. In total, four loading scenarios were investigated; namely bare and encased charges detonated in air, and bare and encased charges detonated under …

Investigating the use of rubber to attenuate the effect of blast load applied to a surrogate lower leg
Landmines are the epitome of the perfect soldier: always ready, never tiring. Landmines also do not choose their victims - it may very well be an armed and protected soldier or an innocent civilian who activates the detonator. As such, land mines have reached epidemic proportions in the Third …
