Application of chemometrics in process analysis
… of ethanol by acetic acid, a batch process, has been investigated on a laboratory scale at the high temperature range of 78 - 80°C. The data has been collected by Raman Spectroscopy and successfully de-noised using Principal Components Analysis. The first principal component (PCI) …

Systems Theoretic Process Analysis of Sociotechnical Systems
… between humans and technology Systems Theoretic Process Analysis (STPA) is a hazard analysis methodology based on systems theory that has been used to improve system safety in various industries, including healthcare, aviation, nuclear power, and automotive design. However, if hazard analysts …

Studies in process analysis and control in batch reactors
… the development of novel techniques for better analysis and control of chemical processes carried out in batch reactors. The problems of pH measurement and sampling, linked to the implementation of NMR and HPLC on-line analysers, are presented as key areas in this development work. Also, part of …

Systems theoretic process analysis Applied to manned-unmanned teaming
… Prior attempts to perform a safety or security analysis of an autonomous UAV have focused on reliability as opposed to safety. FMEA and FTA calculate the probability of a component failure which is different from preventing a hazard. By following STPA, the requirements generated are directly …

Advanced analytics for process analysis of turbine plant and components
… of a heat exchanger or the feed heating process as a result of its poor performance in the out of normal scenarios. Further tuning by way of alternate activation functions and regularisation techniques had little effect on the ANN model performance. The ANN model was able to accurately …

Amazon UK transshipment stow process analysis through discrete event simulation
… was explored and a proposed transshipment stow process is modelled to examine potential reductions in transshipment cycle time. As Amazon's fulfillment network has grown in size, the function of individual fulfillment center has evolved from shipping customer orders to providing a network-level, …

System-Theoretic Process Analysis of a Novel Airborne Laser Communication System
… and novelty of such a system warrant a hazard analysis technique that can fully address the associated challenges of collaboration while the system is in an early concept phase of design. System-Theoretic Process Analysis (STPA) is a proactive hazard analysis technique rooted in Systems Theory. …

Extending the human controller methodology in systems- Theoretic Process Analysis (STPA)
Traditional hazard analysis techniques are grounded in reliability theory and analyze the human controller-if at all-in terms of estimated or calculated probabilities of failure. Characterizing sub-optimal human performance as "human error" offers limited explanation for accidents and is inadequate …

Systems-theoretic process analysis and safety-guided design of military systems
… software enabled systems demand a new hazard analysis and safety-guided design technique in order to meet stringent safety standards and expectations. System Theoretic Process Analysis (STPA) proves to be a powerful tool to identify, describe and help mitigate hazards from the earliest …

System theoretic process analysis of electric power steering for automotive applications
… such as FMEA (Failure Mode and Effect Analysis) or FTA (Fault Three Analysis) have been used to analyze failures in automotive systems, there are limitations when it comes to design errors, flawed requirements, human factors implications, and component interaction accidents in which all …

Self-directed curriculum renewal: A process analysis in one university French program
… related to a more traditional Munby-style needs analysis (Munby, 1978) and complement it with a learning environment analysis which they call a Means Analysis. In this study, a closely-related concept to Means Analysis called Process Analysis was developed. It was based on data from a major …
