Using Uncrewed Aerial vehicles (UAVs) to rapidly scan areas for potential unexploded ordnance (UXO) can provide an efficiency increase while minimizing detonation risks. We present a complete overview of how such mappings be performed using scalar magnetometers, including initial sensor testing, time stamping validation, data positioning, noise removal, and source model inversion. A test survey...

M an’s long history of technologic development has been marked by a continuing search for improved materials. This effort has resulted in vast arrays of new materials which have affected nearly every aspect of contemporary life, including orthodontics. A significant advance in orthodontic materials was made in the late 1930’s and 1940’s when stainless steel wire and appliances became widely ava...

The millions of pieces of unexploded ordnance (UXO) littering former battlefields are a lingering legacy of World War I. In the Verdun, French démineurs dispose of about 30 tons of chemical ordnance each year; they have been doing so since 1945. China, too, has a chemical battlefield legacy, with more than 120 tons of abandoned Japanese chemical weapons from World War II. The removal of these w...

OBJECTIVE This study examined risk factors for self-reported injury incurred before arrival at Ordnance School for advanced individual training (AIT). STUDY DESIGN During AIT in-processing, soldiers (n=27,289 men and 3856 women) completed a questionnaire that collected demographic and lifestyle information, and asked if the soldier currently had an injury that would affect their AIT performan...

Measures are being taken toward land restoration and explosive remnants of war clearance to aid in worldwide food security. Global demining and ordnance removal efforts are contribiting to health improvements and land availability for sustainable crop growth. This article discusses the problem of food security in the twenty-first century and briefly reviews three sets of concerns that are conve...

The U.S. Army Ordnance Center and School and Pacific Northwest Laboratory have developed a system that employs Artificial Neural Network (ANN) technology to perform diagnosis and prognosis of fuel flow problems in the AGT-1500 gas turbine engine of the M1A1 Abrams tank. This paper describes the design and prototype development of the diagnostic system, referred to as "TEDANN" for Turbine Engine...

This paper presents research that enhances the effectiveness of Explosive Ordnance Disposal (EOD) robots with autonomy and 3D visualization. It describes an approach where autonomous behaviors like Click and Go, Drag for Wire, and Click and Grasp are rapidly formed by combining foundational technologies like Resolved Motion, Inverse Kinematics, and 3D Visualization. Also presented is a flexible...

We will report on first tests of a commercial “imaging metal detector” aimed at trying to assess its potentialities and understand in a broader sense if such systems, possibly in a modified form, could be useful to tackle some aspects of the UXO/mine detection problem. The latter include the detection of shallowly buried Unexploded Ordnance (UXO) (e.g. in Laos) or non minimum-metal mines such a...
