In this paper classification performances of advanced electromagnetic induction (EMI) models are evaluated at Fort Ord, CA live UXO site. The EMI data sets are collected using a next-generation EMI system, such as MetalMapper, in the cued mode. The limitation and valid range of application of advanced models: such as the Ortho Normalized Volume Magnetic Sources (ONVMS), Joint Diagonalization and Differential Evolution, are demonstrated for subsurface targets classification at a Live Site by taking into account the number of objects in a close proximity to the sensor, the size and material heterogeneity of those targets, and the local geologic conditions. The comparisons between classification results achieved by our team, using the advanced classification approach, and other teams are demonstrated.

This paper presents the unconditional Crank -Nicolson finite-difference time-domain (CN-FDTD) scheme method in the cylindrical coordinate for solving underwater electromagnetic induction problems. First, a general CN-FDTD formulation is given, and then numerical results are demonstrated for a loop current source excitation in a conducting multilayer structure. The comparisons between CN-FDTD and traditional FDTD methods are given. The studies demonstrate the accuracy and capability of the proposed algorithm for modeling underwater EMI induction problems in the time domain.

We represents the modular concept and the final structure of Tbilisi State University ELF net standard observation station. The project concerns the consistent development of a dense network for Caucasus and Anatolian-Iranian Plateau tectonic faults system state monitoring. The modular concept provides the possibility to choose the most convenient configuration of the station, based on the specific characteristics of the fault and the operating and maintenance conditions. The station is completely autonomous. It can accumulate and transmit data. In comparison with the first prototypes, the noise characteristics of the station were significantly improved.
