Sensor array calibration by a single reference in presence of measurand non-linear gradient
/ Arpaia, P (U. Naples (main)) ; Baccigalupi, C (CERN) ; Cesaro, U (U. Naples (main)) ; Chadli, M (Picardie U.) ; Coppier, H (Picardie U.) ; Pezzetti, M (CERN) ; Severino, G (U. Naples (main))
A calibration method exploiting a single external reference is proposed for sensors arrays in presence of a measurand non-linear gradient in the system under test. The calibration artifacts due to a non-uniform distribution of the measurand in the system under test, not detected by the single punctual reference sensor, are avoided. [...]

Comparison of different cryogenic control strategies via simulation applied to a superconducting magnet test bench at CERN
/ Arpaia, P (CERN ; U. Naples (main)) ; Coppier, H (Amiens, ESIEE) ; De Paola, D (CERN) ; di Bernardo, M (U. Naples (main) ; U. Bristol (main)) ; Guarino, A (U. Naples (main)) ; Luz Pedemonte, B (Amiens, ESIEE) ; Pezzetti, M (CERN)
Industrial process controllers for cryogenic systems used in test facilities for superconducting magnets are typically PIDs, tuned by operational expertise according to users' requirements (covering cryogenic transients and associated thermo-mechanical constraints). In this paper, an alternative fully-automatic solution, equally based on PID controllers, is proposed. [...]

A Fuzzy-Oriented Solution for Automatic Distribution of Limited Resources According to Priority Lists
/ Pezzetti, M (CERN) ; Inglese, V (CERN) ; Tovar-Gonzalez, A (CERN) ; Coppier, H (ESIEE, Amiens, France) ; Almeida, M (UFMG, Belo Horizonte, Brazil)
This project provides a solution for problems in which there is a limited cryogen resource that supplies several clients in parallel, which can cause the resource’s depletion. This study emerged from the need to solve a specific problem of the Cryogenics Group of the European Organization for Nuclear Research (CERN). [...]
