Wavelet-based Noise Extraction for Anomaly Detection Applied to Safety-critical Electronics at CERN / Waldhauser, Felix (CERN ; Stuttgart U.) ; Boukabache, Hamza (CERN) ; Perrin, Daniel (CERN) ; Dazer, Martin (Stuttgart U.)
Due to the possible damage caused by unforeseen failures of safety-critical systems, it is crucial to maintain these systems appropriately to ensure high reliability and availability. If numerous units of a system are installed in various areas and permanent access is not guaranteed, remote, data-driven condition monitoring methods can be used to schedule maintenance actions and to prevent unexpected failures. [...]

ROMULUSLib: An Autonomous, TCP/IP-Based, Multi-Architecture C Networking Library for DAQ and Control Applications / Yadav, Amitabh (CERN) ; Boukabache, Hamza (CERN) ; Ceesay-Seitz, Katharina (CERN) ; Gerber, Nicola (CERN ; CSEM, Neuchatel) ; Perrin, Daniel (CERN)
The new generation of Radiation Monitoring electronics developed at CERN, called the CERN RadiatiOn Monitoring Electronics (CROME), is a Zynq-7000 SoC-based Data Acquisition and Control system that replaces the previous generation to offer a higher safety standard, flexible integration and parallel communication with devices installed throughout the CERN complex. A TCP/IP protocol based C networking library, ROMULUSlib, was developed that forms the interface between CROME and the SCADA supervision software through the ROMULUS protocol. [...]

Formal Property Verification of the Digital Section of an Ultra-Low Current Digitizer ASIC / Ceesay-Seitz, Katharina (CERN) ; Kundumattathil Mohanan, Sarath (CERN) ; Boukabache, Hamza (CERN) ; Perrin, Daniel (CERN) ; Boukabache, Hamza (CERN)
This paper details our experience with Formal Property Verification (FPV) of the digital section of a mixed-signal Application Specific Integrated Circuit (ASIC) for ultra-low current measurements. The ASIC was developed as a prototype front-end for the future version of the CERN RadiatiOn Monitoring Electronics (CROME), which is a safety-critical system. [...]

Study of an Air Curtain in the Context of Individual Protection from Exposure to Coronavirus (SARS-CoV-2) Contained in Cough-Generated Fluid Particles / Sakharov, Alexandre (Manhattan College (US) ; CERN) ; Zhukov, Konstantin (Russian Academy of Sciences (RU) ; CERN)
The ongoing respiratory COVID-19 pandemic has heavily impacted the social and private lives of the majority of the global population. This infection is primarily transmitted via virus-laden fluid particles (i.e., droplets and aerosols) that are formed in the respiratory tract of infected individuals and expelled from the mouth in the course of breathing, talking, coughing, and sneezing.
