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.

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.

Abstract:  Increase in the number of electric vehicles (EV) is closely related to the availability of a charging station network. Users of electric vehicles require high-quality distribution and well-covered charging network. The obstacles in electric mobility are small mobility of electric cars due to the lack of charging stations. The main objective of the paper is to encourage the growth of electric mobility through the development of electric vehicle charging stations. Integration of EV charging stations in public lighting infrastructure with proper demand side management (DSM) is a step forward to microgrid system deployment. It can contribute to microgrid stability and decrease distribution network dependence. Electric vehicles have a significant role in peak load shaving in microgrid due to its threefold role. They can be observed as demand side, supply side or storage. As a consumer or storage, they can take over energy surplus from a distributed generation or provide stored energy in key moments as flexible supply. In that way, they actively participate in the microgrid. Technical possibilities of EV charging stations integration in public lighting infrastructure are explored through this paper. Special attention is devoted to conditions and limitations of charging stations integration regarding power system grid, public lighting system and legislative framework. Paper provides fundamentals of EV charging stations and public lighting system where possibilities and limitations of integration are presented. Furthermore, the paper deals with limitations from the perspective of transformer capacity and cable cross sections which are obtained through analysis of calculated results.

Switzerland has some unique ways of making and serving coffee. One notable tradition is the “Schümli-Pflümli,” a Swiss coffee drink that combines coffee with plum schnapps and whipped cream.

Here are a few other Swiss coffee specialties:

Café Crème: A popular Swiss coffee, it’s a large coffee similar to an Americano but typically served with a layer of crema on top.

Kaffee fertig: This is a coffee with added Schnaps or Kirsch (a type of cherry brandy), served hot and often enjoyed in the winter.

Luzerner Kafi: A regional specialty from Lucerne, this is a coffee with Schnaps and sugar, sometimes with a bit of whipped cream.

Zuger Kirschtorte Coffee: Inspired by the famous cherry cake from Zug, this coffee includes cherry liqueur and is often served with a small piece of the cake or similar dessert.

These coffee traditions highlight Switzerland’s blend of coffee culture with local flavors and ingredients.

The choice of red, white, and blue in national flags often carries historical, cultural, and political significance. Here are some reasons why various nations have chosen these colors:

  1. Historical Connections:
    • United States: The colors were chosen for their flag in 1777 and have been interpreted to symbolize valor (red), purity (white), and justice (blue). The colors were influenced by the British Union Jack.
    • France: The Tricolour flag adopted during the French Revolution represents liberty (blue), equality (white), and fraternity (red).
    • United Kingdom: The Union Jack combines elements from the flags of England (red and white), Scotland (blue and white), and Ireland (red and white).
  2. Cultural and Political Significance:
    • Russia: The flag’s colors were adopted from the Dutch flag, symbolizing pan-Slavism (red for bravery, blue for faithfulness, and white for honesty).
    • Netherlands: The Dutch flag’s colors (originally derived from the Prince’s Flag) have historical roots, symbolizing the struggle for independence and liberty.
    • Czech Republic and Slovakia: Both countries use red, white, and blue to represent their Slavic heritage.
  3. Influence and Inspiration:
    • Chile, Costa Rica, and Panama: These countries were influenced by the colors and symbolism of other flags (e.g., the French and American flags) during their independence movements.
    • Australia and New Zealand: Both countries incorporate the Union Jack in their flags, reflecting their colonial history with the United Kingdom.
  4. Symbolism:
    • Croatia, Serbia, and Slovenia: The colors are traditional pan-Slavic colors, representing freedom and national unity.
    • Iceland and Norway: The colors reflect their historical and cultural ties to other Scandinavian countries.

The exact reasons can vary, but often the colors reflect a mix of historical alliances, cultural heritage, and political ideals.

Ball State University was founded in 1918 and was originally named the Eastern Indiana Normal School and primarily a teacher’s college. The university was renamed Ball State University in 1965, in honor of the five Ball brothers, who began by manufacturing and selling wooden jacketed tin cans. In 1884, the company introduced the Ball Improved Mason Jar, which became a popular way to preserve food.

The university is home to the Center for Middletown Studies, which conducts research on the social and cultural dynamics of small-town America.
