Visible to the public A Hybrid Detector Network for Nuclear and Radioactive Threat Detection

This post considers a problem of target or source localization based on the measurements from a mobile sensor or a network of sensors. The assumption is that the received signal strength is strictly monotonic with the distance between the target and the sensor. No explicit signal propagation model, neither the structure nor the mathematical description, is assumed or used in localization. It shows that this mere knowledge of monotonicity suffices in locating the unknown target in the absence of noise.


Visible to the public Source Localization by a Network of Imperfect Binary Sensors


In this work, target or source localization and tracking by a network of primitive binary sensors under various imperfections are studied. Detailed analysis and mathematical modeling of imperfect binary sensors are presented. Imperfections include sensor failures of two types, uncertainty and heterogeneity in binary sensor trigger thresholds, presence of noise and non-radial symmetry of sensing ranges. Numerical algorithms for source localization and tracking are proposed along with convergence and asymptotic normality results.

The 2015 IEEE Workshop on Environmental, Energy and Structural Monitoring Systems (EESMS 2015)

The growing strategic importance of environmental, energy, and structural monitoring boosts the need for flexible, effective and innovative solutions for design methods and implementation technologies with strong adaptation and evolution capabilities. This workshop aims to discuss the most recent advances in complex monitoring systems from a cross-disciplinary perspective, encompassing technology, methods and applications.
