Abstract

fetched live from OpenAlex

The Unified Hydraulic Solver (UHS) is a new technique that is better suited to real-time modeling based on a combination of SCADA data and demand estimates than conventional solvers or state estimation methods. However, some of the UHS methods are vulnerable to problems created by dependencies that may exist in the SCADA component of the input data. The paper describes and demonstrates a preprocessor that is capable of locating and removing the most common form of dependency, direct dependency. A second form of input dependency, implicit dependency, is explained and methods to avoid singularity associated with implicit dependencies are described.

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.
