Colloquy (September)

Open agenda; Not Too Organized. Whatever anyone wants to talk about.  We do meet once a month like this.  Use the login credentials at the upper right of our home page.

Evensong “Last Rose of Summer”

We are moving across the street!  Details forthcoming

Join us for lunch 11:45 AM – 1:15 PM every Third Wednesday

University of Michigan Business School Executive Dining Room (Under construction until 2026) | University of Michigan Golf Course Dining Room

If we were running that upgrade of the dining facility at the business school — instead of Sodexo — we would complete it in six months.  Alas, by some strange bureaucratic configuration, the project is taking 24 months.  Until then we meet at the Golf Course on the South Athletic Campus where, admittedly, parking is easier.

The Business of Standards Never Stops

Standards for a Kitchen Symphony | November/December 2024

ASTM International (formerly known as the American Society for Testing and Materials) is a globally recognized organization that develops and publishes technical standards for a wide range of products, systems, and services. These standards are used by manufacturers, regulatory bodies, and other stakeholders to ensure that products and services are safe, reliable, and of high quality.

In the field of measurement science, ASTM plays an important role in developing standards and guidelines for measurement techniques and practices. These standards cover a wide range of topics related to measurement science, including the calibration of instruments, the characterization of measurement systems, and the validation of measurement results. They are used by researchers, engineers, and other professionals in academia, industry, and government to ensure that measurements are accurate, precise, and reliable.

ANSI Public Review

 

ASTM standards for measurement science are developed through a process that involves input from experts in the field, including researchers, industry professionals, and regulatory bodies. These standards are updated regularly to reflect advances in measurement science and technology, as well as changes in industry and regulatory requirements.  This is a far better way to discover and promulgate leading practice.  In fact, there are regulations intended to restrain the outsized influence of vertical incumbents in legislative precincts where market-making happens.

Update Status

We continue sorting through anomalies with Godaddy Tech Support to resolve Standards Michigan requirement for frequent and timely updates across all of our platforms.  We got half the problem solved last month when we upgraded to WordPress 6.8.1 but updating was slow on mobile devices.  Our normal course of business will not be interrupted as far as our daily colloquia is concerned but we cannot predict the outcome on the images which are an essential part of our work.

  • Posts are not updating across all platforms — particularly on X on iPhones.  Usually a caching problem and not one we haven’t seen before.
  • Some images will not center.
  • Footer and right-side widgets not loading properly.

The good news is that all our content, including media, survived the WordPress upgrade.  The next step in our “GoDaddy Journey” will be to edit our widgets to reflect our new business address; still proximate to the University of Michigan South Athletic Campus — across the street from our former office with an Olive Garden very nearby.

Always surprises but none that we cannot handle.  Much like  hardware in ICT, software must also be maintained.

This page will be posted to our X-feed: @StandardsMich to remind our colleagues and followers that software needs to be “maintained”

Three Felonies a Day: How the Feds Target the Innocent

Department of Justice | June 24, 2004

The average professional in this country wakes up in the morning, goes to work, comes home, eats dinner, and then goes to sleep, unaware that he or she has likely committed several federal crimes that day. Why? The answer lies in the very nature of modern federal criminal laws, which have exploded in number but also become impossibly broad and vague.

In Three Felonies a Day, Harvey A. Silverglate reveals how federal criminal laws have become dangerously disconnected from the English common law tradition and how prosecutors can pin arguable federal crimes on any one of us, for even the most seemingly innocuous behavior.

The volume of federal crimes in recent decades has increased well beyond the statute books and into the morass of the Code of Federal Regulations, handing federal prosecutors an additional trove of vague and exceedingly complex and technical prohibitions to stick on their hapless targets.

The dangers spelled out in Three Felonies a Day do not apply solely to “white collar criminals,” state and local politicians, and professionals. No social class or profession is safe from this troubling form of social control by the executive branch, and nothing less than the integrity of our constitutional democracy hangs in the balance.

The Chapel in the Sorbonne

“Patience is the companion of wisdom.”

St. Augustine of Hippo

Sacred Spaces



Solar Panels on King’s College Chapel Roof

“…The solar panels will populate the gothic chapel roof, producing an approximate 105,000 kWh of energy a year – enough to run the chapel’s electricity, and saving around £20,000 in energy bills per year. The college confirmed that any excess energy would be sold off to the national grid.

King’s College Announcement

Solar Panels on King’s College Chapel Roof

Solar panels perform better when listening to music:

A 2013 study by researchers at Imperial College London and Queen Mary University of London showed that solar panels actually work better when exposed to music, of multiple genres. Scientists at the university proved that when exposed to high pitched sounds, like those found in rock and pop music, the solar cells’ power output increased by up to 40 percent. Classical music was also found to increase the solar cells’ energy production, but slightly less so than rock and pop, as it generally plays at a lower pitch than pop and rock. Whether they know it or not, British band Coldplay are just one of the artists benefitting from this research. During their 2021 tour, they installed solar photovoltaic panels in the build-up to each show, “behind the stage, around the stadium and where possible in the outer concourses”…

BS 7671 Requirements for Electrical Installations

The Major Differences in Electrical Standards Between the U.S. and Europe

Representative Calculation: (WAG)

To determine how much electrical power and lighting 12 kilowatts (kW) will provide for an educational facility, we need to consider the following factors:

    1. Power Distribution: How the 12 kW will be distributed across different electrical needs such as lighting, computers, HVAC (heating, ventilation, and air conditioning), and other equipment.
    2. Lighting Requirements: The specific lighting requirements per square foot or room, which can vary based on the type of facility (classrooms, libraries, laboratories, etc.).
    3. Efficiency of Lighting: The type of lighting used (e.g., LED, fluorescent, incandescent) as this affects the power consumption and lighting output.

We start with lighting.

    1. Lighting Efficiency:
      • LED lights are highly efficient, typically around 100 lumens per watt.
      • Fluorescent lights are less efficient, around 60-70 lumens per watt.
    2. Lighting Power Calculation:
      • 12 kW (12,000 watts) of LED lighting at 100 lumens per watt would provide: 12,000 watts×100 lumens/watt=1,200,000 lumens
    3. Illumination Requirements:
      • Classroom: Approximately 300-500 lux (lumens per square meter).
      • Library or laboratory: Approximately 500-750 lux.
    4. Area Coverage:
      • If we target 500 lux (which is 500 lumens per square meter), we can calculate the area covered by the lighting: (1,200,000 lumens)/ 500 lux=2,400 square meters

Now we need to allocate power to other loads.

    1. Lighting: Assuming 50% of the 12 kW goes to lighting:
      • Lighting Power: 6 kW (6,000 watts)
      • Using the previous calculation: 6,000 watts×100 lumens/watt=600,000 lumens
      • Area Coverage for lighting (at 500 lux): (600,000 lumens)/500 lux=1,200 square meters
    2. Other Electrical Needs:
      • Computers and equipment: Typically, a computer lab might use around 100 watts per computer.
      • HVAC: This can vary widely, but let’s assume 4 kW is allocated for HVAC and other systems.

Breakdown:

    • Lighting: 6 kW
    • Computers/Equipment: 2 kW (e.g., 20 computers at 100 watts each)
    • HVAC and other systems: 4 kW

Summary

    • Lighting: 12 kW can provide efficient LED lighting for approximately 1,200 square meters at 500 lux.
    • General Use: When distributed, 12 kW can cover lighting, a computer lab with 20 computers, and basic HVAC needs for a small to medium-sized educational facility.

The exact capacity will vary based on specific facility needs and equipment efficiency.
