Klipper is an open source firmware for 3D printers that distributes the workload between a general-purpose computer (such as a Raspberry Pi [1]) and one or more underlying microcontrollers on the 3D printer. [2] [3] The separation claims to allow for more advanced control compared to traditional firmware that runs solely on the printer's ...
The latest model (Prusa MK4 on sale as of March 2023) is available in both kit and factory assembled versions. The Prusa i3's comparable low cost and ease of construction and modification made it popular in education and with hobbyists and professionals, with the Prusa i3 model MK2 printer receiving several awards in 2016.

Israel claimed no tanks were damaged during Operation Protective Edge, with the Trophy Active Protection system performing over a dozen interceptions of anti-tank weapons including Kornet, Metis, and RPG-29. [42] The system, by identifying the source of fire, on occasion also allowed tanks to kill the Hamas anti-tank team. [42]
The command hosts the GPETE (General Purpose Electronic Test Equipment) Calibration and Maintenance School (GCAMS), Advanced Calibration Technician School (ACTS), and physical/dimensional calibration (Phase B&D) schools, and participates in the joint service Precision Physical and Dimensional Calibration School (PHYS-D).
Model predictive control (MPC) is an advanced method of process control that is used to control a process while satisfying a set of constraints. It has been in use in the process industries in chemical plants and oil refineries since the 1980s.
In control theory, advanced process control (APC) refers to a broad range of techniques and technologies implemented within industrial process control systems. Advanced process controls are usually deployed optionally and in addition to basic process controls. Basic process controls are designed and built with the process itself, to facilitate ...
The Mark 33 GFCS was a power-driven fire control director, less advanced than the Mark 37. The Mark 33 GFCS used a Mark 10 Rangekeeper , analog fire-control computer. The entire rangekeeper was mounted in an open director rather than in a separate plotting room as in the RN HACS, or the later Mark 37 GFCS, and this made it difficult to upgrade ...
In USSR the Gundlach periscope was known as MK-4 (harking to the British designation, as Russian sources openly confirm that it was copied from samples acquired with British-supplied tanks) [2] and implemented in all tanks (including the T-34 and T-70). At the end of World War II this technology was adopted throughout the world and used ...
