From a school district’s perspective, the two advantages of portable classrooms are low initial cost and short time between specification and occupancy. They are intended to provide flexibility to school districts, enabling quick response to demographic changes and providing the ability to be moved from one school to another as demographics change. In reality, portable classrooms are seldom moved and become permanent fixtures of the school.
A Modular Control Lab Equipment and Virtual Simulations for Engineering Education
Vanessa Young, et. al | Kennesaw State University Department of Mechanical Engineering
Abstract: Hands-on experiences in engineering education are highly valued by students. However, the high cost, large size, and non-portable nature of commercially available laboratory equipment often confine these experiences to lab courses, separating practical demonstrations from classroom teaching. Consequently, mechanical engineering students may experience a delay in practical engagement as lab sessions typically follow theoretical courses in subsequent semesters, a sequence that differs from mechatronics, electrical, and computer engineering programs. This study details the design and development of portable and cost-effective control lab equipment that enables in-class demonstrations of a proportional-integral-derivative (PID) controller for the trajectory and speed control of a DC motor using MATLAB Simulink, as well as disturbance control. The equipment, composed of a DC motor, beam, gears, crank, a mass, and propellers, introduces disturbances using either propellers or a rotating unbalanced mass. All parts of the equipment are 3D printed from polylactic acid (PLA). Furthermore, the beam holding the propellers can be attached to Quanser Qube lab equipment, which is widely used in control laboratories. The lab equipment we present is adaptable for demonstrations, classroom projects, or as an integral part of lab activities in various engineering disciplines.

IEC technical committees and subcommittees Ω SMB Tabulation
Much economic activity in the global standards system involves products — not interoperability standards. Getting everything to work together — safely, cost effectively and simpler — is our raison d’etre.
Manufacturers, testing laboratories, conformance authorities (whom we call vertical incumbents) are able to finance the cost of their advocacy — salaries, travel, lobbying, administration — into the cost of the product they sell to the end user (in our cases, estate managers in educational settlements). To present products — most of which involve direct contact with a consumer — at a point of sale it must have a product certification label. Not so with systems. System certification requirements, if any, may originate in local public safety requirements; sometimes reaching into the occupational safety domain.
Our readings of the intent of this technical committee is to discover and promulgate best practice for “systems of products” — i.e. ideally interoperability characteristics throughout the full span of the system life cycle.
To quote Thomas Sowell:
“There are no absolute solutions to human problems, there are only tradeoffs.”
Many problems have no solutions, only trade-offs in matters of degree. We explain our lament over wicked problems in our About.

ARCHIVE
The United States National Committee of the International Electrotechnical Commission (USNA/IEC) seeks participants and an ANSI Technical Advisory Group (US TAG) Administrator for an IEC subcommittee (Multi-Agent System) developing standards for power system network management. From the project prospectus:
Standardization in the field of network management in interconnected electric power systems with different time horizons including design, planning, market integration, operation and control. SC 8C covers issues such as resilience, reliability, security, stability in transmission-level networks (generally with voltage 100kV or above) and also the impact of distribution level resources on the interconnected power system, e.g. conventional or aggregated Demand Side Resources (DSR) procured from markets.
SC 8C develops normative deliverables/guidelines/technical reports such as:
– Terms and definitions in area of network management,
– Guidelines for network design, planning, operation, control, and market integration
– Contingency criteria, classification, countermeasures, and controller response, as a basis of technical requirements for reliability, adequacy, security, stability and resilience analysis,
– Functional and technical requirements for network operation management systems, stability control systems, etc.
– Technical profiling of reserve products from DSRs for effective market integration.
– Technical requirements of wide-area operation, such as balancing reserve sharing, emergency power wheeling.
Individuals who are interested in becoming a participant or the TAG Administrator for SC 8C: Network Management are invited to contact Adelana Gladstein at agladstein@ansi.org as soon as possible.
This opportunity, dealing with the system aspects of electrical energy supply (IEC TC 8), should at least interest electrical engineering research faculty and students involved in power security issues. Participation would not only provide students with a front-row seat in power system integration but faculty can collaborate and compete (for research money) from the platform TC 8 administers. We will refer it to the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones.
The bookwheel, also known as a revolving bookcase, was invented by an Italian scholar and polymath named Agostino Ramelli. Ramelli was born in 1531 in Ponte Tresa, a town in present-day Italy, and he lived during the Renaissance period.
Ramelli’s invention, described in his work titled “Le diverse et artificiose machine del capitano Agostino Ramelli” (The Various and Ingenious Machines of Captain Agostino Ramelli), was published in 1588. This book showcased a collection of 195 mechanical devices.
Ramelli’s work contributed to the growing interest in mechanical inventions during the Renaissance period. His bookwheel design remains a fascinating example of early engineering and ingenuity, highlighting the desire for knowledge and practical solutions in the pursuit of learning and scholarly endeavors.
2026 NEC Articles 645-646-647 Information Technology Equipment, et. al First Draft Report
2026 NEC Articles 645-646-647 Information Technology Equipment, et. al Second Draft Report
The standard of care for wiring safety for data centers — a continually expanding presence in education communities even before the pandemic — is established in National Electrical Code Articles 645 (Information Technology Equipment), Article 646 (Modular Data Centers) and Article 647 (Sensitive Electronic Equipment). You will notice that these articles cover the topic comprehensively and bear the imprint of competing Producer-Interest groups. There are no User-Interest representatives on Code-Making Panel 12 that represent the final fiduciary in education communities even though education communities are one of the largest markets for information and communication technology systems.
The current version of NFPA 70 is linked below:
Transcripts of technical committee action during the 2026 revision (CMP-16) are linked below because they will inform our recommendations for the 2026 National Electrical Code. Keep in mind that the Technical Correlating Committee is moving content around the Code in order to make the NEC easier to use by experts.
CMP-16 First Draft Report | Public Input with Committee Response
The transcripts of technical committee action during the 2023 revision are linked below because they will inform our recommendations for the 2026 National Electrical Code.
Code‐Making Panel 12 Public Input Report
Code-Making Panel 12 Public Comment Report
We will use these in our exploration of what we might propose for improvements in the 2026 revision. Public comment on the First Draft of the 2026 Edition will be received until August 28th.
The issues that have been in play in these articles of the NEC are familiar to veterans of the “food fight” – occupancy classification, cable specifications, fire protection, ventilation, energy consumption, surge protection, licensing of engineers. etc. We look for market-making excesses by opposing stakeholders that seek to limit their risk while raising the (financial) risk to education communities.
We encourage our colleagues to participate in the NFPA code development process directly. We also encourage stakeholders in education communities — students, faculty and staff to join us during any of the teleconferences we co-host with the IEEE Education & Healthcare Facilities Committee 4 times monthly in both European and American time zones. See our CALENDAR for the next online meeting.
