“I know that I am mortal by nature, and ephemeral;

but when I trace at my pleasure the windings to and fro of the heavenly bodies,

I no longer touch Earth with my feet:

I stand in the presence of Zeus himself and take my fill of ambrosia.”

— Ptolemy, “Mathematike Syntaxis” 150 A.D

Planetariums in schools and colleges play a central in enhancing astronomy and astrophysics education. They provide immersive experiences that can ignite students’ interest and curiosity about the universe, making complex astronomical concepts more comprehensible and engaging.  Observatories do much that but with direct access to telescopes and other observational tools — frequently away from campus — thus allowing them to engage in hands-on learning and real-time data collection.

Establishing research and teaching programs present special occupancy challenges. The cost of high-quality telescopes and equipment, along with the need for a suitable location with minimal light pollution, can be substantial. Additionally, schools require trained staff to guide students in using the equipment and interpreting data. Weather conditions and geographical location also impact the effectiveness of observatories. Despite these hurdles, the educational value of observatories is immense, providing students with unique opportunities to explore the universe and cultivate a passion for scientific inquiry.

Today we examine both occupancies using our SAFER-SIMPLER-LOWER COST-LONGER LASTING discipline.  Use the login credentials at the upper right of our home page at the usual hour.

About Portable Classrooms

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.

Today we break down consultations on titles relevant to the technology and management of the real assets of education communities in the United States specifically; but with sensitivity to the global education markets where thousands of like-minded organizations also provide credentialing, instruction, research, a home for local fine arts and sport.

We steer away from broad policy issues and steer toward technical specifics of public consultations presented by national member bodies of the International Electrotechnical Commission, the International Organization for Standardization, the International Telecommunications Union and the American National Standards Institute.  If there is a likelihood that the titles published by these workgroups will be incorporated by reference into public safety or sustainability legislation; or integrated into the cost structure of education communities in any other way, we will listen carefully and contribute meaningfully where we can.

Vienna Convention on Diplomatic Relations | 1961 

 
“Even apart from the instability due to speculation, there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits — a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities. Enterprise only pretends to itself to be mainly actuated by the statements in its own prospectus, however candid and sincere that prospectus may be. Only a little more than an expedition to the South Pole is it based on an exact calculation of benefits to come. Thus if the animal spirits are dimmed and the spontaneous optimism falters, leaving us to depend on nothing but a mathematical expectation, enterprise will fade and die; — though fears of loss may have a basis no more reasonable than hopes of profit had before.”

IEC technical committees and subcommittees Ω SMB Tabulation

IEC and ITU offices | Geneva

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.
