Abstract

fetched live from OpenAlex

Modes of representation are key elements in communicating the properties of natural and built environments. This research proposes a capture and representation method for daylighting dynamics in interior and exterior spaces for the photopic (daytime vision) and melanopic (biological clock) portions of the electromagnetic spectrum. The proposed representations of physical ambiences situate quantitative physical information in space and can be displayed as immersive representations for better communication between architects and other stakeholders in the building industry. A digital tool was developed for low-cost, automated surveys using lightweight Raspberry Pi microcomputers and associated Camera Modules (RPiCM). The method allows visualizing the qualitative and quantitative aspects of lighting patterns using High Dynamic Range (HDR) images that generate luminance maps, accurately render human perception and subsequently generate photopic/melanopic dominance maps. The resulting spatial representations become communication tools to identify the photopic/melanopic dominance of architectural components and support design initiatives from architects.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
