A study of past accidents in the chemical process industry (CPI) has been carried out. It is found that the majority (73%) of the accidents were caused by technical and engineering failures. Based on the causes of accident and types of equipment failures, five common features of accident in the CPI were identified. The analysis reveals that the contribution of the design to accidents is signifi...

You should be able to use your identity provider of ...

A number of efforts have been recently devoted to fault modeling, fault simulation and test generation for asynchronous circuits (Shi and Makris 2004). Simulation based approach for testing gate delay faults in asynchronous sequential circuits was proposed by Sur-Kolay et al (2000). Shi and Makris (2006) have proposed a test method for path delay faults based on a design for test strategy. In s...

The envisioned identity ecosystem will affect many people in many ways, but the “steering” process will have questionable legitimacy unless it is open and genuinely representative of users’ interests. More generally, we question whether any putatively representative stakeholder process can be perceived as publicly legitimate in the...
