Water and Electricity

Supporting swimming pools with electricity involves various essential functions such as filtration, heating, lighting, and sanitation. Ensuring safety and energy efficiency is crucial, and pool owners can take steps to minimize electricity costs and environmental impact. Key points:

Filtration and Circulation: Swimming pools rely on electric pumps to circulate water through filters, removing debris and maintaining water quality.

Heating: Electric heaters or heat pumps are used to regulate water temperature for comfort, especially in colder seasons.

Lighting: Underwater and pool area lighting enhance safety and aesthetics, typically powered by electricity.

Chlorination and Sanitation: Electric chlorinators or ozone generators help maintain water cleanliness and hygiene.

Automation: Electric control systems enable pool owners to manage filtration, heating, and lighting remotely for convenience and energy efficiency.

Energy Efficiency: Pool owners can invest in energy-efficient equipment, like variable-speed pumps and LED lighting, to reduce electricity consumption and operating costs.

Operations and Maintenance: Regular electrical maintenance ensures safe and reliable pool operation, preventing electrical faults and hazards.  The electricity cost for pool operation can be significant, so pool owners should consider energy-efficient practices and equipment to reduce expenses.

Today we break down the literature for building, maintaining and supporting the computing infrastructure of education settlements.  We use the term “infotech” gingerly to explain action for a  broad span of technologies that encompass enterprise servers and software, wireless and wired networks, campus phone networks, and desktop computers that provide administrative services and career tech video production.   The private sector has moved at light speed to respond to the circumstances of the pandemic; so have vertical incumbents evolving their business models to seek conformance revenue.  Starting 2023 we break down the topic accordingly:

Infotech 200:  Wired and wireless infrastructure for education and administration related to teaching sciences and supporting fine and lively arts

Infotech 400:  Physical system middleware for research facilities; data center location, power supply, cooling systems, fire suppression, security, monitoring and management.

The literature radiates continually by consortia, open-source, or ad hoc standards-setting domains rather than the private standards system administered by global and standards setting bodies; to wit:

International:

IEC (EN 50600), IET, ISO, ITU

Freely Available ICT Standards

IEEE

Education & Healthcare Facility Electrotechnology Committee

United States:

ASHRAE

Energy Standard for Data Centers

ATIS

BICSI

Data Center Operations and Maintenance Best Practices

INCITS, NFPA, NIST, TIA (942)

Everywhere else:

3GPP & 3GPP2,  Apache Software Foundation,  ISTE,  OneM2M,  Uptime Institute

The ICT domain is huge, replacing physical libraries.  The foregoing is a highly curated sample.

We continue to include teaching and learning media standards on our colloquia however it is likely that will break up this topic into at least two related colloquia as 2022 proceeds; with primary focus on the design, construction and maintenance of the physical ICT infrastructure.  Much depends upon the interest of our clients, colleagues and other stakeholders.  We collaborate closely with the IEEE Education and Healthcare Electrotechnology Committee.

Campus Outdoor Lighting

“The Starry Night” | Vincent van Gogh

The IEEE Education & Healthcare Facilities Committee has completed a chapter on recommended practice for designing, building, operating and maintaining campus exterior lighting systems in the forthcoming IEEE 3001.9 Recommended Practice for the Design of Power Systems for Supplying Commercial and Industrial Lighting Systems; a new IEEE Standards Association title inspired by, and derived from, the legacy “IEEE Red Book“.  The entire IEEE Color Book suite is in the process of being replaced by the IEEE 3000 Standards Collection™  which offers faster-moving and more scaleable, guidance to campus power system designers.

Campus exterior lighting systems generally run in the 100 to 10,000 fixture range and are, arguably, the most visible characteristic of public safety infrastructure.   Some major research universities have exterior lighting systems that are larger and more complex than cooperative and municipal power company lighting systems which are regulated by public service commissions.

While there has been considerable expertise in developing illumination concepts by the National Electrical Manufacturers Association, Illumination Engineering Society, the American Society of Heating and Refrigeration Engineers, the International Electrotechnical Commission and the International Commission on Illumination, none of them contribute to leading practice discovery for the actual power chain for these large scale systems on a college campus.   The standard of care has been borrowed, somewhat anecdotally, from public utility community lighting system practice.  These concepts need to be revisited as the emergent #SmartCampus takes shape.

Electrical power professionals who service the education and university-affiliated healthcare facility industry should communicate directly with Mike Anthony (maanthon@umich.edu) or Jim Harvey (jharvey@umich.edu).  This project is also on the standing agenda of the IEEE E&H committee which meets online 4 times monthly — every other Tuesday — in European and American time zones.  Login credentials are available on its draft agenda page.

Quantum Computing

Is it a fact—or have I dreamed it—that, by means of electricity,

Today we break form from our normal custom of assessing conceptual movement in stabilized safety and sustainability standards for education settlements and, instead, venture into a domain that will inform nearly everything we do; and with gathering pace.

We begin with the action among the experts in the organizations listed below:

  1. National Institute of Standards and Technology (NIST):
    • NIST’s Post-Quantum Cryptography Standardization: NIST is working on standardizing cryptographic algorithms that are secure against quantum attacks. The goal is to ensure that data remains secure even with the advent of quantum computers. This involves selecting algorithms through an open competition, which began in 2016, and is still ongoing.
    • Quantum Information Program: NIST conducts research and develops standards related to quantum information science, including quantum computing, quantum communication, and quantum metrology.
  2. Quantum Economic Development Consortium (QED-C):
    • Formed as part of the National Quantum Initiative Act, QED-C aims to enable and grow the quantum industry in the U.S. It involves various stakeholders, including industry, academic institutions, and government agencies, working together to identify and address standards and other needs to foster a robust quantum ecosystem.
  3. National Quantum Initiative (NQI):
    • Established by the National Quantum Initiative Act in 2018, NQI coordinates efforts across multiple agencies, including NIST, the Department of Energy (DOE), and the National Science Foundation (NSF), to advance quantum information science. This includes the development of standards, infrastructure, and research to support quantum technologies.
  4. International Standards:
    • While primarily international, organizations like the International Telecommunication Union (ITU) and the International Organization for Standardization (ISO) have working groups focusing on quantum technologies. U.S. participation in these groups helps ensure that global standards align with U.S. interests and priorities.
  5. Federal Agencies and Research Programs:
    • The DOE, NSF, and other federal agencies fund research and development in quantum computing, which often includes aspects related to standards and best practices. For example, the DOE’s Quantum Information Science (QIS) Research Centers and NSF’s Quantum Leap Challenge Institutes.
  6. Industry-Led Initiatives:
    • Several industry consortia and companies are actively involved in developing quantum computing standards. Organizations like the IEEE have working groups focused on quantum computing and quantum communications standards.

Overall, the U.S. approach to quantum computing standards is multifaceted, involving federal agencies, industry consortia, academic research, and participation in international standard-setting bodies.

Abstract:  With the advent of Solid State Lighting came a renewed interest in the study of flicker. Potential effects include brightness enhancement, but also discomfort, ocular fatigue, phantom and stroboscopic effects. Both IEEE and IEC developed new metrics, but at the time of writing no firm consensus has been reached. Yet previous lamp studies in the Laplace laboratory showed that various flicker phenomenon are present on different lamps, but this feature is not documented. This paper focus on flicker changes w.r.t. applied voltage. The Indonesian power grid network is indeed characterized by large voltage variations; our purpose is to detect which lamps may exhibit too elevated flicker levels during out of nominal excursion and map such behavior with other electrical characteristics.

ABSTRACT: At the dawn of the fourth industrial revolution, we are witnessing a fast and widespread adoption of artificial intelligence (AI) in our daily life, which contributes to accelerating the shift towards a more algorithmic society. However, even with such unprecedented advancements, a key impediment to the use of AI-based systems is that they often lack transparency. Indeed, the black-box nature of these systems allows powerful predictions, but it cannot be directly explained. This issue has triggered a new debate on explainable AI (XAI). A research field holds substantial promise for improving trust and transparency of AI-based systems. It is recognized as the sine qua non for AI to continue making steady progress without disruption. This survey provides an entry point for interested researchers and practitioners to learn key aspects of the young and rapidly growing body of research related to XAI. Through the lens of the literature, we review the existing approaches regarding the topic, discuss trends surrounding its sphere, and present major research trajectories.
