Analysis of rime ice accumulation at Mont Bélair and design of transmission lines
Bibliographic record
Abstract
The objective of this thesis is to review current approaches for the specification of design loads for rime ice and to propose improvements based on an analysis of field data provided by Hydro-Quebec. Hydro-Quebec established an experimental site on Mont Belair in 1994 for the purpose of obtaining much more detailed data on ice accretion in real time for both glaze ice and rime ice. In this study, rime ice events were identified, analyzed and characterized in terms of their recurrence, severity and relationship to winds. IEC-60826 (2000) recommended procedures are used to calculate design rime ice and wind-on-ice loadsusing the ice load map of CSA C22.3 No. 1-01. The Extreme Type I (Gumbel) distribution is chosen for rime ice in the calculation of design loads based on a reliability-based method. Design rime ice loads derived from the two procedures show that the rime design loads based on short term data at Mont Belair are compatible with IEC-60826 (2000) provisions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
