The design and architecture of a system for automatic Improvised Explosive Devices detection to protect sensitive areas with minimal human interaction is presented. The system, called ACE for “Army Counter IED Enhanced”, employs a variety of statistical analysis, pattern recognition and human machine interface in conjunction with adaptive mechanisms. ACE combines four different kinds of inputs: image...
In this paper, we present the concept of "Ease of Driving" or EoD rating for road scene environment. We introduce the Classification by Holistic Analysis of Scene Environment (CHASE) algorithm to automatically classify the EoD rating using computer vision and machine learning techniques. With the CHASE algorithm we were able to achieve an accuracy of 86.84 % to classify the EoD. In the near...
In this paper, we present a compressed sensing based framework for a wireless sensor based biological sensing system for recording the frequency of fish electric organ discharge. We investigate the trade-offs between the parameters of compressed sensing, such as sampling matrix, reconstructed signal's signal to noise ratio, and compression ratio. The measured results show that our framework can be...
We propose a method to identify persons using home electric appliances with accelerometer. Proposing method improves the accuracy of the power management system in the home, such as HEMS (Home Energy Management System) and EoD (Energy on Demand). We aim to detect the timing of using appliances before using them, and to identify who use them with acceleration sensor. Detecting the timing of using appliances...
Recent rapid decreases in Air Force Explosive Ordnance Disposal personnel manning has raised questions of how to stabilize this essential emergency response capability. The amount of knowledge lost every year is shown in increasing retirements, voluntary separations, and battlefield losses. This has driven a corresponding fading of conventional ordnance handling skills due to personnel being primarily...
One of the most difficult aspects of maintaining port and maritime security is the detection, localization, and classification of submerged explosive devices, biochemical agents, and contraband including narcotics. The Explosives Ordnance Disposal (EOD) community has expressed the need for improved methods of detection to augment current capabilities. SubChem Systems Inc. and the U.S. Naval Research...
Free space optical (FSO) communication has enjoyed a renewal of interest driven by increasing data rate requirements and the crowding of the RF spectrum, affecting both commercial and military sectors. Military communications must also deal with intentional or unintentional jamming, as well as frequency allocation restrictions, neither of which affects FSO. The U.S. Naval Research Laboratory (NRL)...
This paper presents a derivation of the Maximum Likelihood (ML) detector for acoustic signals that have propagated through a random or uncertain ocean environment. The derivation requires probability distribution functions (pdfs) of relevant signal and noise parameters belonging to the exponential class. (A companion paper describes how available knowledge of the environment and the Maximum Entropy...
