Secrecy in Multiagent Systems
TLDR
We introduce a general framework for reasoning about secrecy requirements in multiagent systems and extend earlier definitions of secrecy and nondeducibility. Expand

Ultrawide-bandwidth fully-polarimetric ground penetrating radar classification of subsurface unexploded ordnance
TLDR
An ultrawide-bandwidth (UWB) ground penetrating radar (GPR) was used to collect fully-polarimetric backscattered data from 10 to 800 MHz using the previously developed dielectric-loaded horn-fed bow-tie antenna. Expand

Fast and accurate calculation of physically complete EMI response by a heterogeneous metallic object
TLDR
A new numerical technique for fast and accurate representation of EMI responses for heterogeneous objects is pursued here, applicable to any three-dimensional heterogeneous object placed in an arbitrary time-varying EMI field. Expand

A Man-Portable Vector Sensor for Identification of Unexploded Ordnance
The identification and discrimination of unexploded ordnance using low-frequency electromagnetic induction is an expensive and difficult process, typically beset by low data diversity and high… Expand

A modified dipole model for target discrimination in EMI sensing
As an inverse problem, UXO (unexploded ordnance) discrimination requires fast forward models to estimate the response of target to sensor sources. In EMI sensing, the most well developed models… Expand

The Orthonormalized Volume Magnetic Source Model for Discrimination of Unexploded Ordnance
TLDR
We introduce a fast and accurate numerical technique for the solution of electromagnetic induction sensing problems called the orthonormalized volume magnetic source model. Expand

Semantic integration of file-based data for grid services
TLDR
We present a solution for constructing semantic data services for an earth-sciences data grid (the UK NERC DataGrid). Expand

High frequency electromagnetic induction sensing for non-metallic ordnances detection
High frequency (>100 kHz) electromagnetic induction (HFEMI) sensing phenomena are investigated for nonmetallic ordnances detection and discrimination. HFEMI responses are studied using numerical and… Expand

THE NERC DATAGRID PROTOTYPE
The NDG project began in September 2002. The aim of the project is to utilise the promise of grid technologies to allow members of a virtual organisation (the NERC community) to share environmental… Expand

UXO classification procedures applied to advanced EMI sensors and models
TLDR
In this paper, the detailed steps of UXO classification procedure using the advanced EMI sensors and models are presented along with the processing and analysis approaches that are used to generate a prioritized dig list. Expand
