Marconi e l'innovativo parco antenne di Coltano
Bibliographic record
Abstract
Tra la fine del 1902 e l’inizio del 1903, Guglielmo Marconi manifesto' la sua intenzione di costruire una potente stazione radiotelegrafica intercontinentale in Italia ed avvio' per questo scopo dei contatti con le autorita' italiane. L’intento originario di Marconi, illustrato anche al re Vittorio Emanuele III, era quello di costruire una stazione radio “ultra potente” (cioe' concepita per servizi intercontinentali), in grado di collegare l’Italia con il Sud America. Tuttavia, questo ambizioso obiettivo venne presto abbandonato, probabilmente a causa della difficolta' tecnica di una trasmissione wireless su una così grande distanza e la stazione venne quindi proposta per fornire collegamenti radio con l’America del Nord e le colonie italiane nell’Africa Orientale. Per apprezzare quanto fosse innovativo questo progetto di Marconi, basti ricordare che nel 1903, esistevano nel Mondo solo tre stazioni ultra potenti: una in Gran Bretagna, una negli Stati Uniti ed una in Canada.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
