Abstract

Elizabeth Weckman describes two of her projects, her PhD work that used lasers to investigate the velocities and temperatures in a burning pan of liquid, and work with the Waterloo Fire Department to develop improved training for fire fighters. Her PhD experiments have been used in recent years as benchmark data by international research teams developing computer codes to predict fire responses.  The training director of the Waterloo Fire Department became aware of her work after watching a dramatic short video showing her experiments. This led initially to collaborative work to improve training of fire fighters and subsequently to funding from the Canada Foundation for Innovation program for the $5.6 million University of Waterloo Fire Research Lab that has the capability of creating a two-storey house fire at full scale.

Abstract

Oral history interview with Dr. Elisabeth Weckman, Professor of Mechanical Engineering at the University of Waterloo. Dr. Weckman enjoyed math, sciences, history, and art in high school and eventually elected to take engineering at university instead of archeology or architecture. She started in systems design engineering but switched to mechanical, where her first co-op job was at a copper mine in Turkey.  She was introduced to combustion engineering by a professor who ignited an aerosol can in her presence, convincing her that “this is more exciting than plastic gears.”  Her PhD research used lasers to study the velocities and temperatures in a burning pan of liquid that moved to accommodate the stationary lasers. In the last four or five years, these data have been used as benchmark data for international teams developing computer models for fires. The training director of the Waterloo Fire Department became aware of her work after watching a dramatic short video showing her experiments. This led initially to collaborative work to improve training of fire fighters and subsequently to funding from the Canada Foundation for Innovation program for the $5.6 million University of Waterloo Fire Research Lab that has the capability of creating a two-storey house fire at full scale. She describes the evolution of the field of Fire Protection engineering that now has roots in mechanical, civil, electrical, chemical, and systems design engineering and requires knowledge of physiology to investigate how fire gases impact humans as they’re trying to escape from a fire. She advises high-school students who are curious about careers in engineering – or any field – to be adventurous and not fear making a wrong decision, she believes in learning experiences, not failures. She encourages graduate students to measure their successes in the context of the work they are doing and the individuals they are working with, instead of being fixated on journal publications. She looks forward to the development of holistic solutions in Fire Protection engineering that include “social things, policy, economics, environment.”

Abstract

Le choix de devenir ingénieur s’est dessiné dès un jeune âge pour Madiha El Mehelmy Kotb alors que son professeur de 5e année du primaire a remarqué son « talent pour les mathématiques ». Ayant grandi avec un père ingénieur, Madiha découvre rapidement son intérêt pour ce domaine. Elle début le programme d'ingénierie des matériaux à l'université américaine du Caire, mais à la suite du décès inattendu de son père, elle et son mari déménagent au Canada. Elle obtient son diplôme en ingénierie mécanique à l'université Loyola de Montréal en 1976, ayant été la seule femme de sa cohorte. 

Après quelques années passées au Nigeria, elle revient au Canada pour obtenir une maîtrise en génie mécanique et accepte par la suite un poste au ministère du travail du Québec afin d’élaborer des règle et normes pour les chaudières et les appareils sous pression. Elle devient membre du National Board of Boiler and Pressure Vessel Inspectors et fait part de comités techniques connexes de l'American Society of Mechanical Engineers (ASME). Elle devient inspectrice en chef des chaudières et appareils sous pression pour le Québec. Elle devient éventuellement vice-présidente de l'évaluation de la conformité pour l'ASME, puis membre du comité de gouvernance de l'ASME et, enfin, elle devient également la 132e présidente de l'ASME, soit la deuxième femme à obtenir le mandat et la première femme canadienne à occuper la présidence. 

En outre, elle participe à des initiatives dans le domaine de l'énergie nucléaire, en assistant à la construction, à la mise en service et au déclassement de la centrale nucléaire Gentilly 2. À sa retraite de son poste au gouvernement du Québec, elle travaille comme consultante et rédige un chapitre du livre « Daughters of the Nile : Egyptian Women Changing Their World » (Filles du Nil : des femmes égyptiennes qui changent leur monde), destiné à inspirer les étudiantes.

Abstract
Mechanical engineer Madiha Kotb describes her calling as "engineers do fix things". Life-saving equipment found in hospitals is designed and maintained by engineers. Society takes engineering achievements for granted, even though they are essential and everywhere in every-day life: from plumbing fixtures to electricity to the buildings that we live in. "Unfortunately", she says, "engineers did not used to be good communicators" – though initiatives like the oral history project are changing this.

Abstract
Dr. David Weaver describes his 16 years of retirement as "travelling around the world solving big problems". Always an avid modeler, one of his first initiatives as a new professor at McMaster University was to build a model of Cape Breton Island control structures for the hydro-electric power stations. He used the model to identify and resolve potential problems converting Megawatts of water power into electricity, and as a tool to design the various components. The work, when published, was used globally to design these control structures.

Abstract
Mechanical engineer Dr. Martin Fandrich describes one of his design-build projects – a boat lift. The lift reaches under the water surface to pick up the boat and rotates it to the left or right for a forklift to take it to dry storage. The owner of a boat that was at the limit of the lift's capacity offered his vessel for a load test. Dr. Fandrich recalls "I am not a mariner – but it was a very expensive-looking boat!" Fortunately, the new lift functioned perfectly

Abstract
Madiha Kotb's fifth grade teacher noted her "talent in math" and that, plus marking her 16th birthday with Niel Armstrong's moon walk, led to her decision to choose a career in engineering. She started the materials engineering program at the American University in Cairo, but with the unexpected passing of her father, she and her husband moved to Canada, and she completed her degree at Loyola in Montreal in 1976. After a couple of years in Nigeria, she returned to Canada to do a Masters Degree in Mechanical Engineering, and took a job with the Quebec Department of Labour to develop regulations and standards for boilers and pressure vessels. She became a member of the National Board of Boiler and Pressure Vessel Inspectors and related technical committees of the American Society of Mechanical Engineers (ASME). Eventually she became Chief Boiler Inspector for Quebec. She became Vice President of Conformity Assessment for ASME, then a member of the ASME Board of Governors, and, finally, served as the 132nd President of ASME. She was also aligned with nuclear power initiatives, seeing the construction, commissioning, and eventual decommissioning of the Gentilly 2 nuclear power plant. In retirement, she has worked as a consultant and written a chapter of the book "Daughters of the Nile, Egyptian Women Changing Their World", intended to inspire female students.

Abstract
Dr. David Weaver describes his youthful interest in gasoline-engine powered go-karts, home-built radios, servicing cars, and how this led him to study mechanical engineering. He left his first job with the Ford Motor Company in Oakville to return to university for a Master's degree on satellites for Spar Aerospace and then a PhD in mathematics and physics. He found a university position and began researching nuclear for Ontario Hydro Research and hydroelectric power generation for Nova Scotia Power. He contributed to a model study of flood protection for the City of Venice conducted by the Dutch Hydrodynamics Laboratories in Delft. He worked on a fusion energy project the Joint European Taurus (JET) in England. In retirement, he has worked for the Canadian Nuclear Safety Commission, and with Babcock and Wilcox, Ontario Power Generation, and Atomic Energy of Canada. He talks of the evolution of computational tools from slide rules to computers and their applications to autonomous vehicles – and the importance of selecting the appropriate tool to max the complexity of a problem.
