Excel's logical functions test whether a statement or data is true or false, before enabling the program to carry out an action based on the result. They are useful for analyzing data, automating ...

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...

For the first time, researchers have performed logic operations with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods open up research possibilities ...

The NOT function in Microsoft Excel is a built-in Logical function that reverses the logic of its argument. It ensures that one value is not equal to another. When given TRUE, NOT returns FALSE. When ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

It’s possible to use an 8:1 multiplexer to implement any 3-input logical function, but can we use it to implement a 4-input function? On the one hand, some logic problems never seem to go away. On the ...

Fuzzy logic extends classical binary reasoning by allowing truth values to vary continuously between 0 and 1, thereby modelling uncertainty, imprecision and partial membership in complex systems.

How can cells be programmed to respond to complex signals and make targeted decisions, similar to a logical circuit in a computer? An interdisciplinary team from two research groups at the Centre for ...
