NASA is investigating passive wireless sensor technology to reduce instrumentation mass and volume in ground testing, air flight, and space exploration applications. Vehicle health monitoring systems (VHMS) are desired on all aerospace programs to ensure the safety of the crew and the vehicles. Pervasive passive wireless sensor networks facilitate VHMS on aerospace vehicles. Future wireless sen...

Key to this dis cov ery was the rec og ni tion of a group of Palaeozoic, sub ma rine vol ca nic rocks, named the Mount Attree volcanics, which had pre vi ously been mapped as part of the Lower Ju ras sic Telkwa For ma tion (Woodsworth et al., 1985). The Lower Telkwa vol ca nic rocks are not con sid ered pro spec tive for VHMS de pos its be cause they formed in a subaerial, compressional en vi r...

The massive sulphide deposit at Kantienpan Cu-Zn mine is hosted by volcano sedimentary succession known as the Areachap Group, in the eastern part of Namaqua Metamorphic Province, South Africa. The deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted m...

Abstract To improve the accuracy of partial discharge (PD) pattern recognition by jointing time-domain (TD) and frequency-domain (FD) information, a time-frequency (TF) fusion method via convolution neural network (CNN) is proposed in this paper. Firstly, PD signals are represented waveform images transformed into envelope variational mode decomposition-based Hilbert marginal spectrum (VHMS). S...

Recent seafloor exploration has shown that volcanic-hosted massive sulfides (VHMS) occur in modern silicic calderas formed by highly explosive eruptions at substantial water depths. Sampling of these has so far been restricted to surficial deposits. Ancient analogs provide a time-integrated view of the structure and fill of deepwater calderas, but constraints on paleo-water depths have previous...

MRI-based personalized virtual heart models (VHM) are a useful tool for reconstructing scar distribution and identifying VT circuits planning catheter ablation procedure, an effective therapy preventing sudden cardiac death from in patients with myocardial infarction. However, the MRI resolution used to reconstruct VHMs may not be sufficient accurately detect all circuits, possibly leading erro...

Wearable sensors and electronic devices have gained a lot of attention during the last few years. The advances in low power wearable gadgets research venue field energy harvesting to exclude or supplement battery’s power. Solar is suitable source gadgets. This work presents novel solar based jacket that can in-situ vital health monitoring system (VHMS). developed VHMS comprised measure several ...

From ground tests to operations on orbit and on the Moon, many space applications could benefit from small, passive, wireless sensors. Eliminating wires in spacecraft could reduce launch costs through the reduction of mass and lead to reduced fabrication costs. Development of wireless Vehicle Health Monitoring Systems (VHMS) will enable more sensors and increase safety. It is for these reasons ...

Gold in the Ariab district (Red Sea Hills, Sudan) is mined gossans developed over volcanogenic massive sulphide (VHMS) deposits formed context of a Tonian ensimatic arc Haiya terrane, Neoproterozoic Arabo-Nubian Shield. All primary gold occurrences belt, whatever their style (VHMS-, quartz lode- or shear-zone-hosted), appear, however, to have been syn-to late-kinematic, i.e., final Pan-African ...
