A major problem in exploration seismology entails estimating subsurface structures and properties via linearized inversion. The problem is often called ''least-squares migration" where seismic imaging is posed as an iterative least-squares problem. The iterative solution employs the method of...

Rapid characterization of complex fluids, especially sensing emulsion stability, is crucial for many industrial applications, ranging from pharmaceutical industry to petroleum production. Electrochemical impedance spectroscopy (EIS) is a powerful tool for electrical characterization of such...

In any geological sequestration projects, monitoring and verification are essential components in ensuring storage integrity. Seismic methods are regarded as a feasible way to monitor the subsurface CO2 because of their sensitivity to a rock’s pore space content. Therefore understanding the...

The Canadian oil sand industry operates three phase gas-liquid-solid hydrotransport pipelines to transport oil sand ore from mines to processing facilities. This hydrotransport process is critical to downstream separation activities, given the conditioning steps that occur within it: (i) lump...

The Kennetcook-Windsor basin is a part of the large composite Maritimes Basin in Atlantic Canada. Subsurface seismic data indicate a very complex basinal history in terms of syn-depositional deformation and superimposition of numerous episodes of fault reactivation in the basin. Faults mapped...

A wireless sensor network (WSN) consists of spatially distributed sensor nodes which are deployed to monitor some process of interest. Although WSNs are very promising, the distributed nature, attributes of wireless networks, and availability of limited resources in WSNs introduce significant...

Oscillations are a fundamental principle of neural operation, organized into a hierarchy of frequency bands with the dominant rhythm alternating within and across behavioral states. During states of sleep and anesthesia, brain activity in forebrain regions displays two major distinct activity...

Seismic velocity dispersion in crystalline rock is investigated through experimental measurements on two natural quartzite specimens. The quartzites are thermally damaged to induce low aspect ratio cracks and the shear and Young’s moduli are measured across a range of effective pressures, from...

Simultaneous source acquisition, or blended acquisition, has become an important strategy to reduce the cost of seismic surveys by allowing overlapping between different sources. The major technical challenge associated with this acquisition design is the strong interferences caused by the...
