Peak Finding in Noisy Data using Windowed Curve-Fitting – Part One

In Mathematics on November 1, 2013 at 8:10 pm

This is the first of a two-part article that focuses on a method for detecting peaks in noisy data.  Part One will discuss the signal model as well as the least-means squares method of quadratic curve fitting.  Part Two will discuss the detection criteria from the quadric coefficients, general applications for peak-finding as well as short videos of this particular algorithm working on synthesized test data.  This sort of algorithm is not unique, and has many applications in engineering and science.

The Alpha Gala hosted by the Chambre de Commerce et d’Industrie on May 9, 2013 in Saint-Laurent, Quebec.

The Chamber of Commerce of Saint-Laurent has a history that spans over thirty years and on May 9, they organized the 2013 Alpha Contest. They did this as part of their annual Alpha Gala, the most important economic event in the territory.  At this annual event they celebrated excellence in the business community and recognized the many companies that contributed to economic growth of the region.  I attended the Alpha Gala as part of an industrial outreach delegation from Vanier College.  As a member of this delegation and as an Internship Supervisor for the Computerized Systems Technology Program, I was charged with liaising with top business executives of the region to determine their specific manpower requirements for the foreseeable future.

Part 2: Design and Implementation of a Simple Rocket Motor

In Chemical Propulsion on March 22, 2013 at 1:07 am

This article is the second of a two-part series describing the design of a rudimentary rocket motor implemented using standard, off the shelf components with the goal of demonstrating its propulsive ability. In the first part, mission requirements and motor construction were discussed. In this part, the system is tested and characterized using basic image processing techniques on empirical data obtained from video analysis experimentation.  This series of articles is intended for those with an involved, but not advanced technical knowledge of rocketry.  Readers should not attempt to repeat this experiment without a safe, working knowledge of the risks involved with combustible gases.
