sleep tracking platform as an experimental demonstration.
Such sleep devices help individuals optimize their sleep location and environment to get the most rest and improve their
health and quality of life. The article demonstrates the feasibility of IoT-based at-home sleep and contributes to future
IoT-based sleep research.
" Automated Biosignal Quality Analysis of Electrocardiograms " by Abdelazez et al. from Carleton University addresses
a common and dangerous problem in medical measurements:
contaminated biosignals, which can lead to misinformation
with dire implications such as the misdiagnosis of critical
conditions. Here, the authors introduce a framework of approaches specifically for ECG biosignal quality analysis and
present examples by their own research group as well as other
research groups.
Liu et al. from University of British Columbia present the
next review article " Recent Advances in Sparse Representation Based Medical Image Fusion, " whose coverage ranges
from the conventional local and single-component Sparse
Representation (SR) methods to the latest global and multicomponent SR methods. Medical image fusion combines
multi-source information captured by different imaging modalities and is of great significance for precise diagnosis and
treatment. The article also presents several major challenges
remaining in this direction and discusses future prospects.
We close this topic with " Progress in the Assessment of Arterial Stiffness " by Bolic et al. from University of Ottawa about
arterial stiffness, which is related to the extent of hardening
of the wall of the artery and is an important and independent
predictor of cardiovascular events. The article describes how
this is currently measured and points to new developments
that might lead to measurement outside of specialized clinics
in the future. Hence, it not only reviews existing systems for
estimating arterial stiffness but also points to new directions
in multiple areas including sensors, modeling, and machine
learning.
Next, we move to the Noise Measurement topic and the
article " Thermal Noise Measurement and Characterization
for Modern Semiconductor Devices " by Chen from McMaster
University, who presents a solution for thermal noise measurement and characterization of advanced nanoscale transistors,
providing detailed procedures for the noise measurement
system, DUT design, noise parameter de-embedding, noise
source extraction, and noise source implementation. These
should provide essential insight for system engineers, process
engineers, and circuit designers to enhance the performance of
their noise measurement systems, technologies, and circuit designs for low-noise applications.
Ghaderi and Bahreyni from Simon Fraser University, in
" Synchronous Demodulation for Low Noise Measurements, "
provide an overview and tutorial of the application of synchronous demodulators to low noise measurements. Synchronous
4	

demodulators are used extensively for precise measurements
and reduction of noise bandwidth in a wide range of applications, and this article explains the theory of how to amplify
a narrowband signal to reduce the amount of measurement
noise by considering the process as a multiplier followed by a
low-pass filter, as well as the applications and design considerations for using synchronous demodulation.
The last article in this topic is " Noise-Parameter Measurements of Very-Low-Noise Amplifiers at Ambient and
Cryogenic Temperatures, " by Sheldon and Belostotski from
the University of Calgary, that reviews noise-parameter measurements of RF circuits, such as astronomy-grade low-noise
amplifiers, operating from a few hundred MHz to many GHz.
The article focuses on thermal noise, also known as Johnson or
Nyquist noise, although the same discussions are applicable
to shot noise too.
The last topic of Part A, Machine Learning and Automaton, opens with article " Machine Learning in Measurement
Part 1: Error Contribution and Terminology Confusion " in
which my co-author Al Osman and I take an in-depth look at
the application of Machine Learning (ML) in a measurement
instrument. We describe how ML is used in indirect measurement, how it contributes to systematic and random errors of
measurement, and how to avoid confusion when dealing with
seemingly equal ML and I&M terminology which however
may or may not be the same, in fact being false friends in many
cases. While educational on its own, the article also serves as
a prelude to Part 2 which describes how to quantify the uncertainty caused by ML methods in a measurement instrument.
That article will appear in the SI's Part B which will be published as the May 2021 IMM Issue.
The next article, " Intelligent Agricultural Machinery Using
Deep Learning " by Thomas et al. from University of Manitoba,
focuses on the application of the AI method of Deep Learning to a specific agricultural machinery, while at the same time
offering enough content for the reader to have a good understanding of how to consider AI for not only other agricultural
applications such as sorting and grading produce, but also
other areas in which AI can be part of a system that includes
sensors, hardware and software to make accurate decisions.
In " Application of Machine Learning in Outdoor Insulators
Condition Monitoring and Diagnostics, " El-Hag from University of Waterloo summarizes the process of the application of
ML to outdoor insulator diagnostics, from capturing a signal
until a decision is made, including examples of applying ML
to assess the conditions of both ceramic and non-ceramic insulators, especially those that are related to the Canadian power
grid. Examples of shortcomings of existing methods and the
future potential of ML applications in assessing the health conditions of outdoor insulators are also highlighted.
In the next article, " FOPID Control with Parameter Optimization for Hydrostatically-Actuated Autonomous
