Programmable Logic Controllers

Most robots* are controlled by PLCs. I have tended to avoid the use of PLCs** since I haven't wanted to use ladder logic and PLC hardware and software tends to be expensive.

Turbulent thermal insulation in inertial confinement fusion

 Vincent et al* report the observation and importance of turbulent thermal insulation** in high beta plasmas.
