Exploring technological preventive methods for school shootings

ABSTRACT. The horrific and tragic deaths that have resulted from infamous school shootings have deprived Americans of the sense of security in what has traditionally been a nurturing and safe environment. This paper will discuss different preventive methods for school shootings. The most current preventive methods are examined for fitness based on a variety of school shootings that have occurred in the past. Then a framework for a new school shooting protection device is proposed and evaluated. Concepts from computer vision, anomaly detection, and electromagnetic propulsion are discussed with respect to the proposed framework. Ideally, the goal of the framework presented in this paper is to prevent deaths and injuries from occurring during a school shooting. With the framework, an efficient and comparatively affordable preventive method could be released in the near future.

Illumination Art
“Starry Night Over the Rhône” 1888 Vincent van Gogh
I often think that the night is more alive
and more richly colored than the day.
– Vincent van Gogh
The International Commission on Illumination — is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, colour and vision, photobiology and image technology. The landing page for its standards setting enterprise is linked below:
With strong technical, scientific and cultural foundations, the CIE is an independent, non-profit organization that serves member countries on a voluntary basis. Since its inception in 1913, the CIE has become a professional organization and has been accepted as representing the best authority on the subject and as such is recognized by ISO as an international standardization body.
Illumination technologies influence designs in architectural design, public safety and energy economics in all education communities. We find CIE titles referenced in ISO and IEC standards. Because ISO and IEC standards are incorporated by referenced in the best practice literature published by standards setting organizations in every nation with a private standards setting body (such as ANSI, BSI, DIN, etc.) the CIE titles are worthy of our attention.
We only have resources to track a few of them:
ISO/CIE 20086:2019(E) Light and Lighting — Energy Performance of Lighting in Buildings
ISO 30061:2007(E)/CIE S 020/E:2007 Emergency Lighting
CIE S 015/E:2005 Lighting of outdoor work places
ISO 8995-1:2002(E)/CIE S 008/E:2001 Lighting of Work Places – Part 1: Indoor
There are others that we may track in the fullness of time. Getting illumination technology right is subtle art. The energy to drive normal, steady-state illumination usually consumes 25 to 40 percent of building energy but application of the art — which includes control — can reduce that.
We maintain CIE titles on our periodic Energy, Global, Interiors and Illumination colloquia. See our CALENDAR for the next online meeting; open to everyone.

Luminaires, Lampholders, and Lamps
Best wiring safety practice for the illumination of educational settlement occupancies is scattered throughout the National Electrical Code with primary consideration for wiring fire safety:
- Article 410 – Covers the installation of luminaires (fixtures), lampholders, and lamps, including requirements for wiring, grounding, and support.
- Article 210 – Covers branch circuit requirements, including those for lighting circuits in dwellings and commercial buildings.
- Article 220 – Provides guidelines for calculating lighting loads.
- Article 225 – Addresses outside lighting installations.
- Article 240 – Covers overcurrent protection for lighting circuits.
- Article 250 – Deals with grounding and bonding, which is essential for lighting circuits.
- Article 300 – Covers general wiring methods that apply to lighting circuits.
We have done a fair amount of work on this topic over the years, including writing the chapter on campus outdoor lighting for the soon-to-be-released IEEE 3001.9 Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities.
For our meeting please refer to the workspace we have set up for the 2026 Revision of the NEC:
We will pick through specifics in the transcripts of Code Making Panels 10 and 18.

“Stopping By Woods on a Snowy Evening”
Randall Thompson’s “Frostiana” is a choral cycle based on the poems of Robert Frost. The cycle consists of settings for mixed chorus and piano, and it was premiered in 1959. “Frostiana” was commissioned to celebrate the bicentennial of the town of Amherst, Massachusetts, and it features seven of Frost’s poems set to music by Thompson.
“Stopping by Woods on a Snowy Evening” is one of the poems included in the “Frostiana” cycle. The composition captures the reflective and contemplative mood of Frost’s poem, where the narrator pauses to admire the beauty of a snowy evening in a quiet forest. Randall Thompson’s musical setting adds another layer to Frost’s words, enhancing the emotional impact of the poem.
Thompson’s approach in “Frostiana” is characterized by its accessibility and tonal clarity. His settings aim to convey the meaning and atmosphere of Frost’s poetry through the expressive power of choral music. The entire “Frostiana” cycle is a celebration of both Thompson’s skill as a composer and Frost’s enduring contribution to American literature.
“Stopping by Woods on a Snowy Evening”
By Robert FrostThis is one of my favourite English poems. It is vivid, melancholic, and wistful. The imagery and the final lines have stuck with me for years.

Dahlgren Hall & “Seasoned” Coffee Mug Stories
Named after Rear Admiral John A. Dahlgren, an influential figure in the development of naval ordnance. Its large, open space was ideal for indoor drills and military exercises. The hall was constructed between 1899 and 1903. Its design was overseen by Ernest Flagg, a prominent architect who designed several buildings at the Naval Academy. Today it houses the Drydock Restaurant, a gathering place for midshipmen, faculty, and visitors.
