Abstract

fetched live from OpenAlex

Access control mechanisms that can be implemented in factories, namely, random access, deterministic access, and polling access methods, are investigated. Based on the parameters for an existing mobile data communications system, the performances of the access protocols are compared in a broad sense and in terms of mean message delay performance. An indoor wireless local area network is a convenient and relatively low-cost method of communicating control information and data to and from mobile robots in a factory automation application. The random access protocols perform better in the low utilization range. The polling and deterministic access protocols perform well in the middle to high utilization range. For direct control of an autonomous robot fleet and applications with a small number of stations, the deterministic access methods prevail under the conditions studied. For a polling system, the response time is strongly dependent on the polling overhead, which is very implementation-dependent.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
