Experimental errors in predictions of thermal hazards

Plant/Operations Progress, 1991
AbstractPredictions of critical conditions for thermal runaways are generally based on heat balance models using experimentally generated heat and kinetic data. The accuracy of the predictions depends on the fit of the models and the quality of the thermal data. The relative importance of these factors to the calculated critical reaction conditions are

Measurement, modeling and compensation of thermal error for machine tools

2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015
Thermal error accounts for a large proportion in the error sources of the machine tool. In this paper, the thermal error of a boring and milling machine tool is modeled with the output error model of timing analysis. In order to improve the prediction accuracy, Firefly algorithm is used to optimize the number of groups and the orders of output error ...

Error Analysis in Thermal Purity Determinations

1980
We studied by simulation and experimentaly the deviations occuring at purity determinations. We propose a method for the proper choice of range for evaluation.The continuous and stepwise measuring techniques were compared.

Analysis and reduction of thermal dose errors in MRgFUS treatment

Physica Medica, 2014
ExAblate 2000 MRgFUS system (InSightec) installed in Ospedale Maggiore Niguarda Ca' Granda (Milano, Italy) is currently used to treat uterine fibroids. Through the magnetic resonance thermometry (PRF method), it is possible to monitor the temperature in the target in real-time and compute the treated region calculating the thermal dose.

Thermally-induced soft errors in nanoscale CMOS circuits

2007 IEEE International Symposium on Nanoscale Architectures, 2007
Electrical noise will play an increasingly critical role in future nanoscale CMOS circuit operation character ized by lower supply voltages VDD and smaller device sizes. Both of these downscaling approaches reduce the margin of immunity to thermal noise, alpha particle strikes, and threshold voltage variations.
