The earth’s crust and mantle is known to be anisotropic to the propagation of seismic waves. Despite this knowledge, the analysis and processing of seismic data still primarily assumes isotropy, an assumption that, in the context of active source seismic imaging, is an oversimplification that can...

A capillary-type fluorescent-core microcavity refractive index sensor based on whispering gallery mode (WGM) resonances is presented. The device consists of a glass microcapillary with a thin layer of fluorescent silicon quantum dots (QDs) coated on the channel surface. The high index of the QD...

The Athabasca region located in Northeast Alberta, Canada, hosts many ongoing projects of bitumen extraction from Cretaceous oil sand and Devonian carbonate reservoirs. Despite the importance of the Athabasca region as one of the largest bitumen reserves in the world, the geology and geophysics...

SS precursor imaging and receiver function analysis allow for a detailed investigation of mantle structure of the Earth and subduction dynamics due to their sensitivities to the sharp velocity contrasts within the mantle. By investigating the lateral depth variability of mantle seismic...

The solution of an inverse problem such as the traveltime tomography requires a regu- larization function that constrains the solution and stabilizes the inversion. A traditional regularization method is the one of Tikhonov, which imposes restrictions on the solution such a small norm or...

Amplitude Variation with O set (AVO) inversion is one of the techniques that is being used to estimate subsurface physical parameters such as P-wave velocity, S-wave velocity, and density or their attributes. AVO inversion is an ill-conditioned problem which has to be regularized in order to...

The reflection seismic experiment results in a measurement(reflection seismic data) of the seismic wavefield. The linear Born approximation to the seismic wavefield leads to a forward modelling operator that we use to approximate reflection seismic data in terms of a scattering potential. We...

Machine-learning techniques are emerging as a valuable tool in experimental physics, and among them, reinforcement learning offers the potential to control high-dimensional, multistage processes in the presence of fluctuating environments. In this experimental work, we apply reinforcement...
