The high-performance computing (HPC) memory wall generally refers to the growing disparity between processor speed and memory bandwidth. When processor performance outpaces memory access speeds, this creates a bottleneck in overall system performance, particularly in memory-intensive applications like artificial intelligence (AI).

Insulation monitoring devices (IMDs) are used in ungrounded high-voltage applications to ensure electrical safety, prevent accidents, and ensure reliable operation by continuously monitoring insulation resistance for early fault prediction. A residual current monitor (RCM) is the corresponding device used in grounded systems. In contrast, residual current devices (RCDs) protect against hazards like fires or electrocution in ac-powered applications like electric vehicle (EV) chargers.

A kinematic model is a mathematical representation of a robot’s motion that focuses on the geometric relationships between elements and ignores external forces that affect motion. Kinematic models are used for planning and controlling the paths of industrial robots. Forward kinematics determines the current position and orientation of the end effector based on the angles of each joint in the robot arm.

Positive feedback is primarily used to rapidly amplify a desired change or signal, often in situations where a large response is needed, like triggering a process to reach a specific threshold quickly. It must be carefully managed due to its potential for instability and runaway effects. It’s used in digital electronics to force voltages away from intermediate voltages into ‘0’ and ‘1’ states. A simplified view of an industrial control system is shown in Figure 1.
