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?
Method: Passages of varying lengths from 12 selected SAE and ISO Recommended Practices and Standards were examined using five readability equations (Flesch-Kincaid Grade Level, Gunning Fog Index, SMOG Index, Coleman-Liau Index, and Automated Readability Index) implemented five ways (four online readability tools and Microsoft Word 2013 for Windows). In addition, short test passages of text were used to understand how different readability tools counted text elements, such as words and sentences. Results and conclusions: The mean readability scores of the passages from those 12 SAE and ISO Recommended Practices and Standards ranged from the 10th grade reading level to about 15th. The mean grade reading levels computed across the websites were: Flesch-Kincaid 12.8, Gunning Fog 15.1 SMOG 12.6, Coleman-Liau 13.7, and Automated Readability Index 12.3. Readability score estimates became more consistent as the length of the passage examined increased, with no noteworthy improvements beyond 900 words. Among the five readability tools, scores typically differed by two grade levels, but the scores should have been the same. These differences were due to how compound and hyphenated words, slashes, numbers, abbreviations and acronyms, and URLs were counted, as well other punctuation and text elements. These differences occurred because the sources for these equations often did not specify how to score various punctuation and text elements. Of the tools examined, the authors recommend Microsoft Word 2013 for Windows if the Flesch-Kincaid Grade Level is required.

The “lightning effect” seen in carnival tricks typically relies on a scientific principle known as the Lichtenberg figure or Lichtenberg figure. This phenomenon occurs when a high-voltage electrical discharge passes through an insulating material, such as wood or acrylic, leaving behind branching patterns resembling lightning bolts.
The process involves the creation of a temporary electric field within the material, which polarizes its molecules. As the discharge propagates through the material, it causes localized breakdowns, creating branching paths along the way. These branching patterns are the characteristic Lichtenberg figures.
In the carnival trick, a high-voltage generator is used to create an electrical discharge on a piece of insulating material, such as acrylic. When a person touches the material or a conductive object placed on it, the discharge follows the path of least resistance, leaving behind the branching patterns. This effect is often used for entertainment purposes due to its visually striking appearance, resembling miniature lightning bolts frozen in the material. However, it’s crucial to handle such demonstrations with caution due to the potential hazards associated with high-voltage electricity.
Electrical Switch Station #8
This project restores the Old Art Gallery building for a new electrical switching station. The 1904 building was originally the campus powerhouse, supplying electricity and steam to the young Berkeley campus. As the campus grew, power demands exceeded its capacity and, in 1930, a new central plant opened in the southwest part of campus. In 1934, the former powerhouse building reopened as a gallery to display art and served this purpose until a new University Art Museum opened on Bancroft Way in 1970. The building was subsequently used for storage for more than 50 years.
In restoring and structurally improving the Old Art Gallery building to house the new Switch Station #8, the small brick building that began its storied life as a powerhouse more than 100 years ago will become a key component in UC Berkeley’s 100% clean energy future.

“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West
Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.
He used a kite and a key to demonstrate that lightning was a form of electricity.
This experiment marked an important milestone in understanding the nature of electricity
and laid the foundation for the development of lightning rods and other lightning protection systems.
Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems
To paraphrase the NFPA 780 prospectus:
- This document shall cover traditional lightning protection system installation requirements for the following:
(1) Ordinary structures
(2) Miscellaneous structures and special occupancies
(3) Heavy-duty stacks
(4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors
(5) Structures housing explosive materials
(6) Wind turbines
(7) Watercraft
(8) Airfield lighting circuits
(9) Solar arrays - This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.
(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power. Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)
- This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.
“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height
“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.
Related grounding and bonding requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code. This standard does not establish evacuation criteria.
The current edition is dated 2023 and, from the transcripts, you can observe concern about solar power and early emission streamer technologies tracking through the committee decision making. Education communities have significant activity in wide-open spaces; hence our attention to technical specifics.
Public input on the 2026 revision is receivable until 1 June 2023.
We always encourage our colleagues to key in their own ideas into the NFPA public input facility (CLICK HERE). We maintain NFPA 780 on our Power colloquia which collaborates with IEEE four times monthly in European and American time zones. See our CALENDAR for the next online meeting; open to everyone.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard
Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:
Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.
Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.
Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.
Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.
Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.
Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.
Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.
The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.

Thunderstorm | Shelter (Building: 30/30 Rule)
The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:
- Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
- Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
- Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
- Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.
It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.
Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)
There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.
Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.

Transmission Planning Using a Reliability Criterion
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.

June 15:FERC Finalizes Plans to Boost Grid Reliability in Extreme Weather Conditions
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.
Joint Federal-State Task Force on Electric Transmission
“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.”

During today’s colloquium on fire safety we will review all of the concepts tracking in the Group A tranche; soon to be discussed during the Committee Action Hearings starting September 22nd.
July 12th
For today’s colloquium on elevators and lifts we will review the following concepts tracking in the Group A tranche:
IBC § 1109.2.1| E30-21, E31-21, et. al | The intent of this proposal(s) is to allow for ramps to serve as an accessible route off an occupied roof instead of requiring standby power on the elevator for that occupied roof.
IBC § 1109.2.1| E30-21, E31-21, et. al | Related to the above. Parking garages and self-service storage facilities have extremely low occupancy loads. Increasing the 4-story limit to 6-
stories for when standby power for elevators is required takes this practical difference in uses into account.
IBC § 1109.2.2| E34-21, et. al | Providing the fire department the option for using the elevator for assisted evacuation in any elevator building using fire department recall; with the additional
improvements of standby power (1009.4.1) at five stories and the fire service access elevator protections at 120 feet.
