Running sets of ROS-based processes are represented in a graph architecture where processing takes place in nodes that may receive, post, and multiplex sensor data, control, state, planning, actuator, and other messages. Despite the importance of reactivity and low latency in robot control, ROS is not a real-time operating system (RTOS).
QF (QP Active Object Framework) is a highly portable, event-driven, real-time application framework for concurrent execution of Active Objects specifically designed for real-time embedded systems. QV (Cooperative Kernel) is a tiny cooperative kernel designed for executing active objects in a run-to-completion (RTC) fashion.
RTLinux is a hard realtime real-time operating system (RTOS) microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.

The editor also used these during edit-time, for example, one could WRITE 2 to produce a listing of the code in group 2, or ERASE 4 to delete all of the lines in group 4. [13] Every line must start with a command keyword following the line number. [13] There is no concept of a "default command" as is the case in BASIC with its optional LET ...
The RCS Software Library is an archive of free C++, Java and Ada code, scripts, tools, makefiles, and documentation developed to aid programmers of software to be used in real-time control systems (especially those using the Reference Model Architecture for Intelligent Systems Design). [1]
Most commonly, however, individual learners or their parents either purchase tutoring time with a private vendor of online tutoring service. Such time may also be made available through the purchase of a book, access to a library, a textbook publisher, or enrollment in a particular school or school system. This is known as one-on-one tutoring.
Race time prediction formula, running course certification. Peter Riegel (January 30, 1935 – May 28, 2018) was an American research engineer who developed a mathematical formula for predicting race times for runners and other athletes given a certain performance at another distance.
