Autonomous Aeromagnetic Surveys Using a Fluxgate Magnetometer
Recent advances in the research of autonomous vehicles have showed a vast range of applications, such as exploration, surveillance and environmental monitoring. Considering the mining industry, it is possible to use such vehicles in the prospection of minerals of commercial interest beneath the ground. However, tasks such as geophysical surveys are highly dependent on specific sensors, which mo...
متن کاملDigital fluxgate magnetometer for the Astrid-2 satellite
The design and performance of the Astrid-2 magnetometer are described. The magnetometer uses mathematical routines, implemented by software for commercially available digital signal processors, to determine the magnetic field from the fluxgate sensor. The sensor is from the latest generation of amorphous metal sensors developed by the Department of Automation at the Technical University of Denm...
متن کاملWhat to use INSTEAD of inhaled corticosteroids in COPD?
Inhaled corticosteroids (ICS) have had an important impact on the management of chronic obstructive pulmonary disease (COPD). When combined with an inhaled long-acting b-agonist (LABA), they improve lung function more than is the case with the LABA alone, improve health status and reduce the number of exacerbations patients experience [1]. There are data to suggest that they modify the decline ...
متن کاملDetection of subsurface inclusions by magnetic flux density measurements using a fluxgate gradiometer
A comparison between published analytical results with measured experimental results of the magnetic field produced by thermoelectric currents of subsurface semi-spherical pure tin inclusions embedded in a copper bar under the influence of an external heating and cooling into the specimen is presented. The experimental magnetic flux density measurements show a reasonable agreement as compared t...
متن کاملThe effect of environmental noise on magnetometer- and gradiometer-based MEG systems
The ability of an MEG system to resolve small or deep sources is solely determined by the achieved signal-to-noise ratio (SNR). Ideal MEG sensors should exhibit a large gain relative to the brain signals and should also effectively attenuate the environmental and brain noise. Designing the system for large signal strength without regard for noise attenuation, or designing for excellent noise at...
