Hogan, James D., Farbaniec, Lukasz, Mallick, Debjoy, Domnich, Vladislav, Kuwelkar, Kanak, Sano, Tomoko, McCauley, James W., Ramesh, Kaliat T.

In this paper, the impact-induced fragmentation of a commercially available hot-pressed boron carbide is explored. Fragmentation has been noted previously by many authors to be important in the impact performance of advanced ceramics, and so this paper seeks to provide some of the first...

Fan, Xianfeng, Zuo, Ming J.

Vibration analysis has been widely used in machine fault feature extraction and diagnosis of rotating machinery. The effects of modulation and nonstationarity in vibration signals collected from a faulty gearbox present challenges for fault feature extraction. Hilbert transform and S-transform...

A model for the mechanics of an elastic solid, reinforced with bidirectional fibers is presented in finite plane elastostatics. The fiber’s resistance to stretch and flexure are accounted for with variational computations of first and second gradient of deformations, respectively. Within the...

Nicholson, M., Flynn, M.R.

e report upon a laboratory experimental study of dense full- and partial-depth locks released gravity currents propagating through a two-layer ambient and over sinusoidal topography of amplitude A and wavelength λ. Attention is restricted to a Boussinesq flow regime and the initial (or slumping)...

Tan, A.W. , Ungarish, M., Flynn, M.R.

We consider the propagation of a gravity current of density ρ c at the bottom of a two-layer stratified ambient in a horizontal channel of height H, in the high-Reynolds number Boussinesq domain. The study emphasizes theoretical-analytical modeling, however, experimental and Navier-Stokes...

Sutherland, B.R, Marleau, L. J., Flynn, M.R.

Gravity currents produced by partial-depth lock-release and travelling along the base of a two-layer stratified ambient are investigated as they propagate along a rising slope. The initial gravity current front speed is found to be consistent with a theory adapted from Shin et al. [“Gravity...

Marleau, L. J., Sutherland B.R., Flynn, M.R.

Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they approach and then propagate up a rising slope. Consistent with the prediction of a WKB-like theory, the gravity current front decelerates in a nearly uniform manner along...

Verma, Aman, Olateju, Babatunde, Kumar, Amit

The demand for hydrogen is likely to increase in the next decade to satisfy the projected growth of the bitumen upgrading industry in western Canada. This paper presents greenhouse gas (GHG) abatement costs and the GHG abatement potential in producing hydrogen from underground coal gasification...

Subramanyam, Veena, Kumar, Amit, Ahiduzzaman, Md

This study was conducted to identify energy efficiency improvement options and assess these opportunities in terms of potential of energy savings and greenhouse gas (GHG) mitigation for the commercial and institutional sector. In addition, associated GHG abatement cost (GHGAC) curves were...

Motamedi, Pouyan, Bosnick, ken, Cui, Kai, Cadien, Ken, Hogan, James D.

There is a great interest in various branches of the advanced materials industry for the development of novel methods (and improvements to existing ones) for the deposition of conformal ultrathin metallic films. In most of these applications, like enhanced solar absorbers and microelectronics,...
