A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers

This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...

Programmable logic devices

Advances in programmable logic devices' architectures are making PLDs suitable for a plethora of applications. The devices now find use in state machines and other highly sequential circuits. In the past two years, bipolar PLD operating speeds have doubled, and emerging CMOS PLDs offer four times the circuitry per chip than the older bipolar versions offered. CMOS PLDs also offer lower operatin...

High-Fidelity DNA Hybridization Using Programmable Molecular DNA Devices

The hybridization of complementary nucleic acid strands is the most basic of all reactions involving nucleic acids, but has a major limitation: the specificity of hybridization reactions depends critically on the lengths of the complementary pairs of strands and can drop (in the presence of other competing strands whose sequences are close to that of a given target strand) to very low values if...
