Title: Josephson Arbitrary Waveform Synthesizer as a Quantum Standard of Voltage and Current Harmonics
Speaker: Dr. Dimitrios Georgakopoulos, Senior Research Scientist, National Measurement Institute, Sydney, Australia
Date/Time:Â Thursday, July 09, 2020, 6:30 pm – 7:30 p.m. EDT
Abstract: Josephson arbitrary waveform synthesizers (JAWS) are becoming a viable technology for national metrology institutes and industry to establish quantum standards of direct and alternating voltage. At the National Measurement Institute of Australia (NMIA) we have extended the application of the JAWS to provide a standard of both the magnitude and the phase of harmonics in a distorted waveform. Harmonic analysis is critical in a number of industrial applications such as electric power systems, power electronics, characterization of systems and materials and acoustics and vibration. At present, in the calibrations of power analyzers, the traceability of the magnitude of the harmonics is based on ac-dc transfer measurements. However, there is a gap in the traceability of the phase of the harmonics relative to the fundamental. The NMIA calibration system uses a JAWS chip from the National Institute of Standards and Technology (NIST), USA, a precision inductive voltage divider and a set of current shunts designed and manufactured by NMIA. For distorted waveforms with harmonic magnitudes from 5% to 40% of the fundamental, the calibration system can measure odd harmonics up to the 39th with magnitude uncertainties better than 0.001 % of the fundamental for voltage (from 0.01 V to 240 V) and current (from 0.005 A to 20 A) waveforms. The best phase uncertainties range from 0.001Â° to 0.010Â° (k = 2.0), depending on the harmonic number and harmonic magnitude. We anticipate that the ability of the JAWS to generate distorted waveforms with the lowest possible uncertainty in the magnitude, and phase spectra will make it a unique tool for low-frequency spectrum analysis.

About this Event
Environmental Entrepreneurship: Bridging Gap between Innovation and Function
Environmental challenges of the current century are systemic threats
to the fabric of our civilization. In this context, environmental
entrepreneurship has emerged as a key mitigation concept that combines
economic and environmental dimensions by leveraging state-of-the-art
technology innovations. Seeing entrepreneurship through the lens of
engineering innovation is crucial to produce actionable theory for
sustainable technology. But what are the environmental entrepreneurship
elements, challenges, and success factors? How can researchers,
technology innovators, and entrepreneurs connect to this emerging field?
This seminar introduces environmental entrepreneurship as the process
of discovering, evaluating, and exploiting market forces that allow to
have effective and fast business cases in environmentally-relevant
markets. The seminar will also discuss views on bridging academic
innovation and technology productization to deliver pragmatic solutions
to environmental challenges of the planet.

IEEE Canada Technology Leadership Monthly Webinar
Speaker: Alan R. Emery, Founder, The Stable Climate Group
Topic: Net Zero 2050? Canadaâ€™s Options in a Human-Caused Hot World
Registration Link: https://events.vtools.ieee.org/m/249205
The sources of human-caused global warming will be presented briefly followed by overwhelming evidence that global warming is real and dangerous. Â The speaker will position Canada in a global hot world context. Next, a synopsis of the scale required to get to net zero 2050 and the psychology of global fossil fuel â€œaddictionâ€ will be discussed.Â Â A broad series of what could be excellent options for an innovative future Canada to lead the world by example with a focus on engineering opportunities combined with social and economic requirements will be outlined. Finally, the more probable trajectory for Canada and the world given the current Canadian and world governance in a predatory capitalistic world will be presented. Â Even in this dangerous future probability, Canada has many favourable options, if it plans carefully.
Alan received his BSc. from the University of Toronto; MSc. from McGill University; and PhD from Cornell University and University of Miami.Â His scientific specialty is ecology and evolution with a focus on marine sciences. He pioneered in direct observation
underwater at night on coral reefs and in fresh water. He was among the first to dive under the ice in the Arctic. He has led expeditions to the Arctic, Atlantic, Pacific and Indian Oceans. He was a research scientist with the Fisheries Research Board of Canada, the Ministry of Natural Resources in Ontario, professor at the University of Toronto, Curator and Sciences Coordinator at the Royal Ontario Museum, President of the Canadian Museum of Nature, and has been the governor, president, or director of many scientific organizations. When his brother fell terminally ill, Alan brought his engineering company back to a profitable position to be sold by his brotherâ€™s family.
He has published nearly 100 scientific, technical, and popular articles and books spanning subjects from marine biology to the management of academic organizations. He has appeared on hundreds of radio and television interviews and has been the subject of, technical advisor for, or written over 150 television shows for CTV, Discovery, and the CBC.
As part of his work with indigenous people, he prepared policy papers for Canada, the World Bank and the UN. In addition, he has worked as a consultant with the Canadian Nuclear Waste Management Organization almost since its inception.
Recently, Alan has moved his primary attention from global biodiversity loss to the solution of human-caused global warming. In 2015, he initiated and is now leading an international group of scientists and engineers to help solve the global warming problems: The Stable Climate Group.
