Rewriting logic is a versatile and expressive framework that unifies the specification of concurrent systems with formal reasoning about their behaviour. It allows researchers and practitioners to ...

Temporal logic provides a formal language with which one can express time-dependent behaviours, facilitating rigorous reasoning about the sequential evolution of system states. This branch of ...

In part one of this series, we looked at the PLC’s internal architecture, briefly discussed Ladder Logic programming, Human-Machine Interfaces, advantages of the PLC’s ability to react consistently ...

A universal passive logic element of positive and negative logic, made on just one transistor, is proposed. The logic element has at least two inputs, as well as three outputs: an OR, an XOR, and an ...
