Magnetic Signature Estimation Using Neural Networks
Ferrous objects in earth's magnetic field cause distortion in the surrounding ambient field. This distortion is a function of the object's material properties and geometry, and is known as the magnetic signature. As a precursor to first principle modeling of the phenomenon and a proof of concept, …

Modelling the induced magnetic signature of naval vessels
… design feature. With recent advances in electromagnetic sensor technology the war time threat to shipping posed by electromagnetically triggered mines is becoming more significant and consequently the need to understand, predict and reduce the electromagnetic signature of ships is growing. There …

Development and Evaluation of Unmanned Aerial Vehicle (UAV) Magnetometry Systems
In this thesis, the procedure of conducting magnetic surveys from a UAV platform is investigated. In the process of evaluating UAVs for such surveys, magnetic sensors capable of operating on a UAV platform were tested using a terrestrial survey, as well as on a UAV-platform. Results were then …

Neogene paleomagnetism and geodynamics of the Hikurangi margin, East Coast, New Zealand
… rheology of continental crust. Extensive paleomagnetic sampling along the Hikurangi margin, on the East Coast of the North Island, has provided new insights into the patterns, rates and timings of tectonic rotation, and also an improved understanding of the magnetic signature of New Zealand …

The significance of indoor:outdoor relationships, and physical and chemical composition in personal exposure to urban particulate matter
… to be diesel engine and vehicle related. The magnetic signature of the dusts collected from the street canyon also varies from dusts collected from other locations, for example the XARM/SIRM ratio is approximately half of other street dusts collected in the West Midlands. Airborne particulate, …

A Design for Test and Security Methodology for Integrated Circuits
… technique to capture integrated circuits' electromagnetic (EM) signature. In this method, the remaining metal and polysilicon layers are utilized as internal magnetic probes to monitor the device's signature and, in the meantime, deprive attackers of layout resources to route HTs. 3D full-wave EM …
