Clean the chicken, put it in a large pot and cover it with cold water. Bring the water to boil.
Add the chicken wings, onions, sweet potato, parsnips, turnips and carrots. Boil about 1 and a half hours. Remove fat from the surface as it accumulates.
Add the parsley and celery. Cook the mixture about 45 min. longer.
Remove the chicken. The chicken is not used further for the soup. (The meat makes excellent chicken parmesan.)
Put the vegetables in a food processor until they are chopped fine or pass through a strainer. Both were performed in the present study.
Add salt and pepper to taste.
(Note: This soup freezes well.) Matzo balls were prepared according to the recipe on the back of the box of matzo meal (Manischewitz).

“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.”
Extended Versions Certain standards are required to be read in tandem with another standard, which is known as a reference (or parent) document. The extended version (EXV) of an IEC Standard facilitates the user to be able to consult both IEC standards simultaneously in a single, easy-to-use document.
A partial list of projects with which we have been engaged as an active participant; starting with the original University of Michigan enterprise in the late 1990’s and related collaborations with IEEE and others: (In BOLD font we identify committees with open consultations requiring a response from US stakeholders before next month’s Hello World! colloquium)

However, and for most issues, we defer to the International Standards expertise at the American National Standards Institute
* A “Hello, World!” program generally is a computer program that outputs or displays the message “Hello, World!”. Such a program is very simple in most programming languages (such as Python and Javascript) and is often used to illustrate the basic syntax of a programming language. It is often the first program written by people learning to code. It can also be used as a sanity test to make sure that a computer language is correctly installed, and that the operator understands how to use it.
We track action in international administrative procedures that affect the safety and sustainability agenda of the education facility industry. From time to time we find product purchasing contracts that contain “boilerplate” requiring conformity to applicable regulations found in the Agreement on Technical Barriers to Trade (TBT). Common examples are found in contracts for the acquisition of information technology and specialty laboratory equipment.
The World Trade Organization TBT Agreement obliges all Parties to maintain an inquiry point that is able to answer questions from interested parties and other WTO Members regarding technical regulations, standards developed by government bodies, and conformity assessment procedures, as well as provide relevant documents. The TBT Agreement also requires that WTO Members notify the WTO of proposed technical regulations and conformity assessment procedures so interested parties can become acquainted with them and have an opportunity to submit written comments.
The Eurocodes are ten European standards (EN; harmonised technical rules) specifying how structural design should be conducted within the European Union. These were developed by the European Committee for Standardization upon the request of the European Commission. The purpose of the Eurocodes is to provide:
A means to prove compliance with the requirements for mechanical strength and stability and safety in case of fire established by European Union law.[2]
A basis for construction and engineering contract specifications.
A framework for creating harmonized technical specifications for building products (CE mark).
Since March 2010 the Eurocodes are mandatory for the specification of European public works and are intended to become the de facto standard for the private sector. The Eurocodes therefore replace the existing national building codes published by national standard bodies, although many countries have had a period of co-existence. Additionally, each country is expected to issue a National Annex to the Eurocodes which will need referencing for a particular country (e.g. The UK National Annex). At present, take-up of Eurocodes is slow on private sector projects and existing national codes are still widely used by engineers.
Eurocodes appear routinely on the standing agendas of several of our daily colloquia, among them the AEDificare, Elevator & Lift and Hello World! colloquia. See our CALENDAR for the next online meeting; open to everyone.

Abstract. Research problem: Readability equations are widely used to compute how well readers will be able to understand written materials. Those equations were usually developed for nontechnical materials, namely, textbooks for elementary, middle, and high schools. This study examines to what extent computerized readability predictions are consistent for highly technical material – selected Society of Automotive Engineers (SAE) and International Standards Organization (ISO) Recommended Practices and Standards relating to driver interfaces. Literature review: A review of original sources of readability equations revealed a lack of specific criteria in counting various punctuation and text elements, leading to inconsistent readability scores. Few studies on the reliability of readability equations have identified this problem, and even fewer have systematically investigated the extent of the problem and the reasons why it occurs. Research questions:
(1) Do the most commonly used equations give identical readability scores?
(2) How do the scores for each readability equation vary with readability tools?
(3) If there are differences between readability tools, why do they occur?
(4) How does the score vary with the length of passage examined?

Ampere current flows through copper or aluminum conductor due to the movement of free electrons in response to an applied electric field of varying voltages. Each copper or aluminum contributes one free electron to the electron sea, creating a vast reservoir of mobile charge carriers. When a potential difference (voltage) is applied across the ends of the conductor, an electric field is established within the conductor. This field exerts a force on the free electrons, causing them to move in the direction of the electric field. The resulting current flow can be transformed into different forms depending on the nature of the device.
Heating: When current flows through a resistor, it encounters resistance, which causes the resistor to heat up. This is the principle behind electric heaters, toasters, and incandescent light bulbs.
Mechanical Work: Current flowing through an electric motor creates a magnetic field, which interacts with the magnetic field of the motor’s permanent magnets or electromagnets. This interaction generates a mechanical force, causing the motor to rotate. Thus, electrical energy is converted into mechanical energy; including sound.
Light: In an incandescent light bulb, a filament heats up ( a quantum phenomena) due to the current passing through it. This is an example of electrical energy being converted into light energy; including the chemical energy through light emitting diodes
Today we dwell on how conductors are specified and installed in building premise wiring systems primarily; with some attention to paths designed to carry current flowing through unwanted paths (ground faults, phase imbalance, etc). In the time we have we will review the present state of the best practice literature developed by the organizations listed below:
Other organizations such as the National Electrical Manufacturers Association, ASTM International, Underwriter Laboratories, also set product and installation standards. Data center wiring; fiber-optic and low-voltage control wiring is covered in other colloquia (e.g. Infotech and Security) and coordinated with the IEEE Education & Healthcare Facilities Committee.

The Federal Energy Regulatory Commission is an independent agency within the U.S. federal government that regulates interstate transmission of electricity, natural gas, and oil. It oversees wholesale energy markets, pipeline infrastructure, and hydroelectric projects, ensuring fair rates and reliability. While independent, FERC operates under the Department of Energy’s umbrella but does not take direct orders from the executive branch.
FERC enforces energy laws, approves infrastructure projects, and regulates market competition. FERC plays a crucial role in balancing economic, environmental, and energy security concerns, aiming to maintain a stable and efficient energy system across the United States. Since the U.S. shares interconnected electricity grids with Canada and Mexico, FERC’s decisions on transmission rules and pricing affect energy flows and grid reliability in both countries.
Our interest lies in closing a technical gap that exists upstream from the building service point and downstream from the utility supply point. Some, not all of it, can be accomplished with titles in the IEEE catalog.
Given the dominance of vertical incumbents in the electric power domain, we have submitted a tranche of reliability concepts into the ASHRAE, NFPA and ICC catalogs — not so much with the expectation that they will be gratefully received — but that our proposals will unleash competitive energies among developers of voluntary consensus standards.
In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.
Reliability:
Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.
Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.
Comment:These 1-hour sessions tend to be administrative in substance, meeting the minimum requirements of the Sunshine Act. This meeting was no exception. Access to the substance of the docket is linked here.
On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.
“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”
At the July 20th meeting of the Federal Energy Regulatory Commission Tristan Kessler explained the technical basis for a Draft Final Rule for Improvements to Generator Interconnection Procedures and Agreements, On August 16th the Commission posted a video reflecting changes in national energy policy since August 14, 2003; the largest blackout in American history.
The purpose of the code is to establish minimum requirements to provide a reasonable level of health, safety, property protection and welfare by controlling the design, location, use or occupancy of all buildings and structures through the regulated and orderly development of land and land uses within this jurisdiction.

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:
Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.
This is a relatively new title in the International Code Council catalog; revised every three years in the Group B tranche of titles. Search on character strings such as “zoning” in the link below reveals the ideas that ran through the current revision:
Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.

Meeting Notes in red
Loss of electric power and internet service happens more frequently and poses at least an equal — if not greater threat — to public safety. So why does neither the National Electrical Code or the National Electrical Safety Code integrate reliability into their core requirements? Reliability requirements appear in a network of related documents, either referenced, or incorporated by reference; sometimes automatically, sometimes not.
NESC Main Committee Membership: Page xii
Apart from the IEEE as the accredited standards developer, there are no “pure non-government user-interests” on this committee; although ANSI’s Essential Requirements for balance of interests provides highly nuanced interpretation. The Classifications on Page xiii represents due diligence on meeting balance of interest requirements.
In our case, we are one of many large universities that usually own district energy plants that both generate and purchase generate electric power (as sometimes provide var support to utilities when necessary; as during the August 2003 North American outage). For University of Michigan, for example, has about 20 service points at 4.8 – 120 kV. Its Central Power Plant is the largest cogeneration plant on the DTE system.

The word “reliability” appears only three times. Should it track in the NESC or should it track in individual state requirements. So neither the NEC nor the NESC couples closely with power and communication reliability; despite the enormity and speed of research.
