In order to be proactive to accidents, there is a need to limit systems’ threats and vulnerabilities by being able to perceive and comprehend them as early as possible. Under this notion, the concept of ‘risk Situation Awareness provision capability’ is introduced, indicating that the elements of a system, tangible or not, have an impact on the enhancement or degradation of the awareness, in re...

control actions and feedback paths. For example, the control structure may represent an aircraft flight crew as a single controller with high-level control actions like execute maneuver and abort maneuver. A complex software system could be represented by a single controller labeled engine controller with basic control actions like increase power and decrease power. Once the analysis has been d...

The H-NS protein was isolated for the first time from Escherichia coli as a contaminant in RNA polymerase preparations (Jacquet et al., 1971). A few years later, on the basis of nucleotide sequence homology, H-NS proteins were identified by different groups in other enteric or related bacteria such as Proteus mirabilis, Serratia marcescens, Salmonella typhimurium and Erwinia chrysanthemi (Usser...

Safety and cybersecurity are two emergent behaviors critical to mission success of Unmanned Aerial Vehicles (UAVs). This paper presents the concepts driving the initial research investigation of a hazard and vulnerability analysis for the integration of manned-unmanned aerial systems (UAS) using System-Theoretic Process Analysis (STPA). The motivation for this analysis is the need to engineer s...

Laboratory safety in colleges and universities has received wider attention as a critical annual inspection by the Ministry of Education. The laboratory environment is complex diverse, with many hazard factors. To effectively prevent occurrence emergencies universities, STAMP/STPA model used to analyze energy management resource-based university. Between 2021 2022, we carried out field observat...
