For the second consecutive year, Logan Maley, Jonathan Armstrong and myself did the grueling Rideau Lakes Cycle Tour.  Ottawa - Kingston - Ottawa, 344 km, in 2 days. A few days before, we managed to schedule a second and last training ride after technical presentations at the Annual H2CAN meeting in Mont Tremblant. and went out rolling towards St-Donat. Three days later, we were ready to attack the RLCT tour . Loaded up our back pockets with energy bars and some sort of special salts Jon brought. took a team picture, and left for Kingston on an epic ride.  After an hour, Logan's bike broke.  Luckily, team car Shane Maley brought a spanking full Record replacement bike.  With some help from Mike the mechanic, off we went.  After some 344 km, with a help of a slight tail wind and the hard work of Calin Focsa for a few hours on the second day, the sweet taste of victory!

and gets nominated for another one of those fancy awards...i guess it's a trend by now. photo courtesy of A. Bellerive Justin Tang thesis now shows that Fickett's model, i.e., a reactive form of the Burgers' equation, reproduces the same type of pulsating instabilities as real detonations! It also recovers the route to chaos via period doubling bifurcations. Space-time diagram showing the modulated amplification of forward facing pressure waves by the location of the reaction zone (controlled by the lead shock strength).  In-phase and out-of-phase passage of pressure waves through the reaction zone modulate the leading shock strength. Figure adapted from his Masters thesis.

The NSERC awards have been announced .  Both Nick Sirmas and Shem Lau-Chapdelaine received the top-of-the-line NSERC Alexander Graham Bell CGS-D awards for their PhD programs.   They follow in Brian Maxwell's footsteps. Congratulations to both for these awards ! Out of the 10 CGS PhD scholarships awarded at UOttawa (only 6 for the full 3 yrs), 2 of them are from our group, the only ones from engineering.
