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 0.001° to 0.010° (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
Future wireless networks (beyond 5G/sixth-generation (6G) networks)
are envisioned to support 3D communication by integrating terrestrial
and aerial networks. The objective is to provide connectivity to a large
number of devices (known as massive connectivity), to support
substantial traffic demands, and expand coverage. However, effective
resource management in future wireless networks is a challenge because
of massive resource-constrained devices, diverse quality-of-service
(QoS) requirements, and a high density of heterogeneous devices. In this
seminar, I will present my recent research progress which is focused on
communication networking aspects of the Internet of Things (IoT), with
emphasis on algorithm design, network architecture development, and
system-level performance analysis. I will provide a brief discussion on
my three most significant contributions which focuses on the design of
novel algorithms and communication protocols for IoT networks, that have
both (i) enhanced network performance, in terms of spectrum efficiency,
coverage, and energy efficiency, and (ii) satisfied a wide range of IoT
devices’ requirements and constraints. I will then share long-term goal
of my research program which is to develop efficient and low complexity
resource management schemes to tackle the challenges of seamless
connectivity of heterogeneous devices anytime and anywhere. Finally, I
will present my short-term objectives in the next five years which are
to develop resource management schemes for massive connectivity in
future terrestrial networks, aerial networks, and self-sustainable
networks (SSNs) while considering different objectives and constraints,
including network scalability, reliability, latency, efficiency
(spectral usage and energy consumption), and complexity.

Webinar: Role of the Smart Grid in Facilitating the Integration of Renewables

Abstract – With the focus on environmental sustainability and energy security, power system planners are looking at renewable energy as supplements and alternatives. But such generation sources have their own challenges – primarily intermittency. It is expected that the smart grid – due to its inherent communication, sensing and control capabilities – will have the ability to manage the load, storage and generation assets (including renewables) in the power grid to enable a large-scale integration of distributed generation. In a smart grid, information about the state of the grid and its components can be exchanged quickly over long distances and complex networks. It will therefore be possible to have the integration of sustainable energy sources, such as wind, solar, off-shore electricity, etc. for smoother system operation. But in order for this to be possible, the electric utility will have to evolve, and change their ways of operation to become an intelligent provider of these services. This lecture introduces the operational characteristics of renewable energy sources, and various aspects of the smart grid – technology, standards and regulations. It also addresses the interplay among distributed generation, storage and conventional generation to provide an efficient operational strategy in the context of the smart grid.

Abstract:
In this ever-changing world, it’s important to have the support of someone who could help and guide us to advance in our career. Women are great achievers, but due to the systemic bias, many are unable to climb up to leadership positions in their career. Women empowerment is very much needed especially in these tough times and promoting women by providing platforms where they could build themselves is need of the hour. Here in IEEE WIE, we understand its importance and try to provide such platforms especially to the women in our society who lag behind in their learning path because of many reasons and couldn’t come up. IEEE wants every woman to achieve what they desire to be. We promote not only women but also men who understand and go by our notion.
ANCWT (Advancing New Canadian Women in Technology) aim is to help women with technical skills in engineering accomplish their goals by providing an employment bridging program. ANCWT was established in 2016 and has collaborated with multiple employers in the engineering field. Therefore, the IEEE-WIE, Ottawa, and ANCWT have come forward and took an oath, that we will strive hard to make women gain the required knowledge and confidence to overcome this barrier and find themselves in the background of every picture. Join us on 10th August 2020, in a seminar in which Dr. Sawsan Abdul Majid, President of ANCWT accompanied by two alumni of ANCWT, Oyaje Omakwu, and Dalia Elimam will and take us through their journey with ANCWT in Canada.

Abstract – A smart city relies on widely distributed smart devices to monitor the urban environment in real-time, collects information for intelligent decision making, and facilitates various services to improve the quality of urban living. The distributed network of intelligent sensor nodes, as well as data centers/clouds where sensor data are stored and shared, constitutes a smart city infrastructure. Smart cities address urban challenges such as pollution, energy efficiency, security, parking, traffic, transportation, and others by utilizing advanced technologies in data gathering and communications interconnectivity via the Internet. It provides real time and remote monitoring for different aspects of data management in areas such as transportation, communication, video surveillance, and sensors distributed throughout the city. Simultaneously, the Smart City building blocks like education, telemedicine, health care, IT applications, pollution management, etc. can be deployed in the IEEE Smart Village initiative to have a greater impact on the rural population throughout the world. through reliable electricity and internet connectivity.
