Available in PDF, EPUB and Kindle. Book excerpt: False positive detections account for a great part of the expense associated with unexploded ordnance (UXO) remediation. Presently fielded systems like pulsed electromagnetic induction systems and cesium-vapor magnetometers are able to distinguish between UXO and other metallic ground clutter only with difficulty. The discovery of giant magnetoresistance (GMR) has led to the development of a new generation of integrated-circuit magnetic sensors that are far more sensitive than previously available room-temperature-operation electronic devices. The small size of GMR sensors makes possible the construction of array detectors that can be used to image the flux emanating from a ferrous object or from a non-ferrous object with eddy currents imposed by an external coil. The purpose of a GMR-based imaging detector would be to allow the operator to easily distinguish between UXO and benign objects (like shrapnel or spent bullets) that litter formerly used defense sites (FUDS). In order to demonstrate the potential of a GMR-based imaging technology, a crude magnetic imaging system has been constructed using commercially available sensors. The ability to roughly determine the outline and disposition of magnetic objects has been demonstrated. Improvements to the system which are necessary to make it into a high-performance UXO detector are outlined.

Book excerpt: The goal of the project was to demonstrate the feasibility of the detection of buried unexploded ordnance (UXO) using giant magnetoresistive (GMR) sensor arrays. 3x3 and 5x5 arrays of off-the-shelf GMR sensors were purchased from Nonvolatile Electronics (NVE) and were interfaced with a data acquisition card and a personal computer. Magnetic images were obtained from a number of ferrous objects, such as threadstock, bolts, and rebar. These images can be interpreted in terms of the remanent magnetic state of the objects. The ability of the GMR sensor approach to discriminate among magnetic objects is assessed and the design of a more realistic UXO detection system is discussed.

This book was released on 2001 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports on demonstrations of two sensor systems conducted at the Badlands Bombing Range in South Dakota. The first demonstration, conducted in 1997 by the Naval Research Laboratory, used the Multisensor Towed Array Detection System. The second demonstration, conducted in 1999 by the Army Corps of Engineers in conjunction with Oak Ridge National Laboratory, used a high-sense helicopter-mounted magnetic mapping system. The systems were evaluated individually and compared to each other. Based on this analysis, the paper concludes that the most appropriate use for the technologies may be in different missions and recommends that revamped testing, with better ground truth, be conducted.

This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 1996, on the Magnetic Test Range at the Marine Corps Air Ground Combat Center, Twentynine Palms, California, the Multisensors Towed Array Detection System (MTADS) underwent its first semi-blind field test. After completing the data acquisition and determining the location of potential ordnance, the Institute for Defense Analyses performed an assessment to determine overall detection performance and unique characteristics of the MTADS. The detection rates for both the magnetometer and the electromagnetic induction system exceeded 80 percent with approximately 30 and 20 false alarms per acre, respectively, for the two detection systems. The magnetic gradiometers exhibited somewhat poorer detection performance than the other two sensor systems. The MTADS also demonstrated excellent accuracy when determining the location and depth of the ordnance. All three sensor arrays exhibited better than 40 cm mean location error and less than 20 cm mean depth error. The data collected at Twentynine Palms was also used to test a magnetic clutter discrimination algorithm based on the relative contribution of induced and remanent magnetization. Employing this algorithm resulted in at least 30 percent fewer false alarms, with minimal loss of unexploded ordnance detection capability when using the magnetometer.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state-of-the-art of Terahertz spectroscopy. It is a modern source for a beginners and researcher interested in THz spectroscopy. The basics and physical background of THz spectroscopy and technology are explained, and important applications are described. The book presents the highlights of scientific research in the field of THz science and provides an excellent overview of the field and future directions of research. Over the last decade the field of terahertz spectroscopy has developed into one of the most rapidly growing fields of spectroscopy with large impact across a wide range of scientific disciplines. Due to substantial advances in femtosecond laser technology, terahertz time-domain spectroscopy (THz-TDS) has established itself as the dominant spectroscopic technique for experimental scientists interested in measurements in this frequency range. In solids and liquids terahertz radiation is at resonance with both phonon modes and hydrogen bonding modes which makes it an ideal tool to study the interaction between molecules in a unique way, thus opening a wealth of opportunities for research in physics, chemistry, biology, materials science and pharmaceuticals. This book provides an easy access to scientists, engineers and students alike who want to understand the theory and applications of modern terahertz spectroscopy.

Book excerpt: New and unpredicted technologies are emerging at an unprecedented pace around the world. Communication of those new discoveries is occurring faster than ever, meaning that the unique ownership of a piece of new technology is no longer a sufficient position, if not impossible. In today’s world, recognition of the potential applications of a technology and a sense of purpose in exploiting it are far more important than simply having access to it. Technological surprise has and will continue to take many forms. A plethora of new technologies are under development for peaceful means but may have un- tended security consequences and will certainly require innovative counterme- ures. A relevant example is the tremendous development in biotechnology that has occurred since the advent of recombinant DNA and tissue culture-based processes in the 1970s. If US government agencies and the defense and academic commu- ties had more clearly recognized the potential for biotechnology to affect fun- mental security and warfighting doctrines 20 years ago, the situation today could be very different. Defense against chemical and biological weapons – from both states and nonstate actors – currently presents a threat that is difficult to predict and for which traditional solutions are increasingly less effective. Nanotechnology has emerged as a well-funded discipline that, like biote- nology, carries the potential for groundbreaking applications and the potential for unpredictable harm. The world is likely 20 years away from the full impact of the nanotechnology on defensive capabilities.

Book excerpt: The authors have done a masterful job of charting the important story of DARPA, one of the key catalysts of technological innovation in US recent history. By plotting the development, achievements and structure of the leading world agency of this kind, this book stimulates new thinking in the field of technological innovation with bearing on how to respond to climate change, pandemics, cyber security and other global problems of our time. The DARPA Model provides a useful guide for governmental agency and policy leaders, and for anybody interested in the role of governments in technological innovation. —Dr. Kent Hughes, Woodrow Wilson International Center for Scholars This volume contains a remarkable collection of extremely insightful articles on the world’s most successful advanced technology agency. Drafted by the leading US experts on DARPA, it provides a variety of perspectives that in turn benefit from being presented together in a comprehensive volume. It reviews DARPA’s unique role in the U.S. innovation system, as well as the challenges DARPA and its clones face today. As the American model is being considered for adoption by a number of countries worldwide, this book makes a welcome and timely contribution to the policy dialogue on the role played by governments in stimulating technological innovation. — Prof. Charles Wessner, Georgetown University The U.S. Defense Advanced Research Projects Agency (DARPA) has played a remarkable role in the creation new transformative technologies, revolutionizing defense with drones and precision-guided munitions, and transforming civilian life with portable GPS receivers, voice-recognition software, self-driving cars, unmanned aerial vehicles, and, most famously, the ARPANET and its successor, the Internet. Other parts of the U.S. Government and some foreign governments have tried to apply the ‘DARPA model’ to help develop valuable new technologies. But how and why has DARPA succeeded? Which features of its operation and environment contribute to this success? And what lessons does its experience offer for other U.S. agencies and other governments that want to develop and demonstrate their own ‘transformative technologies’? This book is a remarkable collection of leading academic research on DARPA from a wide range of perspectives, combining to chart an important story from the Agency’s founding in the wake of Sputnik, to the current attempts to adapt it to use by other federal agencies. Informative and insightful, this guide is essential reading for political and policy leaders, as well as researchers and students interested in understanding the success of this agency and the lessons it offers to others.

Available in PDF, EPUB and Kindle. Book excerpt: his easy-to-grasp book introduces nanotechnology, a fast growing field with applications in a large number of areas. Nanotechnology is increasingly present in manufactured products and in daily life objects. It uses less raw materials to provide similar, improved or new functions for materials and systems. It also allows to cut down costs of objects and processes. This introductory book is divided in two parts. One presents the basics of this new field and introduce the physics involved and its consequences. The topics that are addressed are about nanoscience and nanotechnology, quantum effects, nanomaterials and nanostructures, nanofabrication and the new forms of carbon. The second part present some applications in different areas as well as the issue of risks and toxicity of nanomaterials. The different areas of applications are health, food, nanoelectronics and molecular electronics, nanocatalysis, energy (production, housing and transport), defense and security. We also address the issue of risks and toxicity of nanomaterials. This book is not intended to be a comprehensive presentation of nanotechnology but just a flavor of this exciting area that will be more and more important for our future.

Book excerpt: This book is intended to help satisfy an urgent requirement for up-to date comprehensive texts at graduate and senior undergraduate levels on the subjects in non-destructive testing (NDT). The subject matter here is confined to electrical and magnetic methods, with emphasis on the widely used eddy current and magnetic flux leakage methods (including particle inspection), but proper attention is paid to other techniques, such as microwave and AC field applications, which are rapidly growing in importance. Theoretical analyses relating to the various methods are discussed and the depths of presentation are often governed by whether or not the information is readily available elsewhere. Thus, for example, a considerable amount of space is devoted to eddy current theory at what the author considers to be a reasonable standard and not, as usually experienced, in either a too elementary manner or at a level appreciated only by a postgraduate theoretical physicist. The inclusion of the introductory chapter is intended to acquaint the reader with some of the philosophy of NDT and to compare, briefly, the relative performances of the more important methods of testing.
