Abstract: Described herein is a communication system including a cloud server, a first server, and at least one second server. The first server includes a first communication interface configured to provide reference spectral information referring to at least one reference sample and reference analytical data to the cloud server. Each second server includes a second communication interface configured to provide spectral information related to at least one substance to the cloud server. The cloud server is configured to: generate a calibration model, where the calibration model comprises at least one parameter; apply the calibration model to the spectral information, whereby at least one value for the at least one parameter is extracted; and provide the at least one value for the at least one parameter to the first server. The first server is further configured to determine treatment data using the at least one value for the at least one parameter.

Abstract: Disclosed herein are a communication system, a monitoring system for in-situ monitoring of a substance used in a gas scrubbing process, and related methods. The monitoring system can be used to monitor the at least one substance and provide treatment data for treating the at least one substance. The communication system includes a cloud server, a first server, a second server, and a third server. The first and second servers respectively include first and second communication interfaces configured to provide spectral information to the cloud server. The cloud server is configured to generate a calibration model including at least one parameter; apply the calibration model to the spectral information provided by the second server, whereby at least one value for the at least one parameter is extracted; and provide the at least one value for the at least one parameter to the first server via the first communication interface.

Abstract: The invention relates to a support (1) for rolling cylindrical elements, this support comprising first guide means (2) capable of guiding the cylindrical elements at a height z1. Downstream, in a direction in which the cylindrical elements roll, the said support (1) comprises second guide means capable of guiding the cylindrical elements at a height z2 higher than z1, the friction between the second guide means and the cylindrical elements being lower than the friction between the first guide means (2) and the cylindrical elements.
