Most school districts, colleges, universities and university-affiliated health care systems depend upon a safe and reliable supply of natural gas.  Owing to safety principles that have evolved over 100-odd years you hardly notice them.  When they fail you see serious drama and destruction.

One of the first names in standards setting for the natural gas industry in the United States is the American Gas Association (AGA) which represents companies delivering natural gas safely, reliably, and in an environmentally responsible way.  From the AGA vision statement:

“….(AGA) is committed to leveraging and utilizing America’s abundant, domestic, affordable and clean natural gas to help meet the nation’s energy and environmental needs….”

We do not advocate in natural gas standards at the moment but AGA standards do cross our radar because they assure energy security to the emergent #SmartCampus.  We find AGA standards referenced in natural gas service contracts (for large district energy plants, for example) or in construction contracts for new buildings.  As with all other energy technological developments we keep pace with, improvements are continual even though those improvements are known to only a small cadre of front line engineers and technicians.

AGA has released seventeen redlines containing proposed changes to one of its parent documents for natural gas delivery”  GPTC Z380.1 Guide for Gas Transmission, Distribution, and Gathering Piping Systems. The redlines are listed in the link below:

A Dynamic Equivalent Energy Storage Model of Natural Gas Networks for Joint Optimal Dispatch of Electricity-Gas Systems

Siyuan Wang, et. al

Department of Electrical Engineering, Tsinghua University, Beijing, China

Abstract:  The development of energy conversion techniques enhances the coupling between the gas network and power system. However, challenges remain in the joint optimal dispatch of electricity-gas systems. The dynamic model of the gas network, described by partial differential equations, is complex and computationally demanding for power system operators. Furthermore, information privacy concerns and limited accessibility to detailed gas network models by power system operators necessitate quantifying the equivalent energy storage capacity of gas networks. This article proposes a multi-port energy storage model with time-varying capacity to represent the dynamic gas state transformation and operational constraints in a compact and intuitive form. The model can be easily integrated into the optimal dispatch problem of the power system. Test cases demonstrate that the proposed model ensures feasible control strategies and significantly reduces the computational burden while maintaining high accuracy in the joint optimal dispatch of electricity-gas systems. In contrast, the existing static equivalent model fails to capture the full flexibility of the gas network and may yield infeasible results.

Standard Practice for Assessing Language Proficiency

Committee F43 on Language Services and Products

One of the easiest ways to persuade someone who disagrees with you is to change the subject without them knowing about it.  Application of this method is found in the technical literature that informs safety and sustainability regulations at all levels of government.  Change definitions; change the subject; outcome changed — hence our interest in spoken, written and computer languages.

Almost all technical standards begin with a list of definitions which, among domain experts, are frequently hard won.

From the project prospectus:

Purpose—This practice describes best practices for the development and use of language tests in the modalities of speaking, listening, reading, and writing for assessing ability in accordance with the Interagency Language Roundtable (ILR)2 scale. This practice focuses on testing language proficiency in use of language for communicative purposes.

Limitations—This practice is not intended to address testing and test development in the following specialized areas: Translation, Interpretation, Audio Translation, Transcription, other job-specific language performance tests, or Diagnostic Assessment.   Tests developed under this practice should not be used to address any of the above excluded purposes (for example, diagnostics).

This title was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade Committee.

As of the date of this post we find no changes in the titles developed by this committee; nor do we see any notice of meetings; likely owed to the circumstances of the pandemic. Last Update: April 2020

Language lies at the foundation of all standards-setting so we maintain this title on the standing agenda of several of our daily colloquia.  Its an “evergreen” topic that we can explore every day in every title in every catalog   Feel free to click in to any of our daily colloquia; login credentials at the upper right of our home page.

High Tea

The Idea of a University: John Henry Newman

This tradition has its origins in England during the 18th and 19th centuries.  In the 18th century, the working class would have a substantial meal in the evening after finishing work, and this meal became known as “high tea” because it was eaten at a high, dinner table. It typically included hearty dishes such as meat pies, cold cuts, and other substantial fare.

On the other hand, the upper classes would have a lighter afternoon tea, usually served on low tables. This afternoon tea included finger sandwiches, scones, pastries, and, of course, tea. This more delicate tea was later referred to as “low tea” or “afternoon tea.”

Over time, the distinction between high tea and afternoon tea blurred, and today the term “high tea” is often misused to describe an elegant afternoon tea. However, the original high tea was a working-class meal, while afternoon tea was a more refined social event among the upper classes.

Designing a Telecommunications Service Entrance Room (SER) involves careful consideration of various factors to ensure the effective and reliable operation of the telecommunications infrastructure. Here are some typical challenges associated with designing a SER:

  1. Space Constraints:
    • Limited space can be a significant challenge when designing a SER, especially in existing buildings where retrofitting may be necessary.
    • Adequate space is needed for equipment racks, cable management, and future expansion.
  2. Power and Electrical Requirements:
    • Ensuring a stable and reliable power supply for the equipment is crucial. This involves considerations for power redundancy, uninterruptible power supply (UPS) systems, and proper grounding.
    • Compliance with electrical codes and regulations must be addressed.
  3. Cooling and Ventilation:
    • Telecommunications equipment generates heat, and effective cooling is essential to prevent overheating and ensure optimal performance.
    • Adequate ventilation and air conditioning systems must be designed to maintain a suitable operating temperature.
  4. Cable Management:
    • Managing and organizing a large number of cables can be challenging. Proper cable routing, labeling, and documentation are essential for troubleshooting, maintenance, and future upgrades.
  5. Security:
    • Physical security is crucial to protect the telecommunications equipment from unauthorized access and potential tampering.
    • Access control systems, surveillance, and security policies need to be implemented.
  6. Environmental Considerations:
    • Depending on the location of the SER, environmental factors such as humidity, dust, and potential exposure to water or other contaminants need to be addressed.
  7. Scalability and Future Expansion:
    • Designing the SER with future growth in mind is important. The infrastructure should be scalable to accommodate additional equipment and technologies as the organization’s needs evolve.
  8. Equipment Selection:
    • Choosing the right telecommunications equipment for the specific needs of the organization can be challenging. Factors such as compatibility, performance, and vendor support must be considered.
  9. Interoperability:
    • Ensuring that different telecommunications systems and equipment can work seamlessly together is crucial for the overall effectiveness of the SER.
  10. Reliability and Redundancy:
    • Designing for high reliability and redundancy is essential to minimize downtime. This involves redundant power supplies, network connections, and backup systems.

Addressing these challenges requires a multidisciplinary approach involving telecommunications experts, electrical engineers, facility managers, and IT professionals. Regular maintenance and updates to the SER design should also be part of the overall strategy to ensure ongoing efficiency and effectiveness.
