I perform system level tests on the railway system to ensure operation in nominal and degraded modes. I ensure that all train sub-systems (rolling stock, signaling, traction and infrastructure) work correctly together.

• Design and development of HongYanHe nuclear power plant simulator • Use of customer data to scope, draw, calibrate and test simulator systems: turbine steam and drain, feedwater heaters, chemical and volume control, safety injection, residual heat removal • Lead for the integration of process models of systems in Conventional Island • Non-safety control system: open-loop tests, closed-loop tests, tuning of PID controllers

• Design and development of an intelligent electronic device to supervise the lock-out procedure during repair and maintenance of an injection-molding machine • Design specifications, component selection, prototype building, product testing with live signals in a laboratory setting, writing of an official agency report and a published technical paper • programming of micro-controllers, wireless interface between micro-controllers, sensors, peripherals and computer

- Research Topic: Dynamics and control of Spacecraft in the vicinity of Binary Asteroids - Journal paper to Acta Astronautica, “Dynamics of multi-tethered satellite formations containing a parent body,” by A. Pizarro-Chong and A.K. Misra. - Teaching Assistant for the course Mechanics (Dynamics): reviewed course material, presented tutorials, corrected assignments (6h/week) - Project with the Canadian Space Agency: MATLAB code to estimate the attitude of a satellite given a set of star sensor observations

• Wrote preliminary MATLAB code to estimate the attitude of a satellite given a set of star sensor observations • Wrote preliminary MATLAB code to calculate aerodynamic and solar radiation disturbance forces and torques on a satellite, given its geometry. • Reviewed literature on attitude estimation • Reviewed literature on aerodynamic and solar radiation forces and torques

• Analyzed the secondary air path and oil passages/hardware of several turboshaft and turboprop engines as a member of the Air/Oil Systems Group. • Analyzed the thermal efficiency of the inlet of gas turbine engines and performed preliminary design of the exhaust of engines as a member of the Installations Group. • Participated in conference calls with clients and suppliers in order to evaluate the technical aspects of their work • Conducted tests on gas turbine engines to evaluate their performance

• Development on a 11-degree-of-freedom manipulator to be used for maintenance operations • Determined design parameters and performed design calculations for the preliminary selection of mechanical components • Chose some off-the-shelf components from catalogs • Drew a 4-degree-of-freedom manipulator on Pro-Engineer design software • Obtained the manipulator’s mass and inertia properties, and Denavit-Hartenberg parameters
