In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

The GCOR is supplemented by System Special Instructions, Timetables, Hazardous Materials Instructions, Air Brake and Train Handling Instructions, and General Orders. These documents are issued by each individual railroad. System Special instructions, Timetables, and General Order can modify or amend the General Code of Operating Rules. GCOR 1.3 ...
A technician seeking Universal certification must correctly answer 18 out of 25 questions on each section of the exam. In addition to covering EPA (in particular, Section 608) regulations, the exam also covers basic safety and occupational practices, along with fundamental concepts of stratospheric ozone protection (which are typically part of ...
DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems. It was jointly developed by the safety-critical working group RTCA SC-167 of the Radio Technical Commission for Aeronautics (RTCA) and WG-12 of the European ...
Hazard control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following this hierarchy of controls normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.
Aircraft specific NATOPS manual cover. These manuals are typically about 2 inches thick. These are manuals for specific aircraft models containing standardized ground and flight operating procedures, training requirements, aircraft limitations, and technical data necessary for safe and effective operation of the aircraft.
Although functionally separate, process control and shutdown systems are usually interfaced under one system, called an integrated control and safety system (ICSS). Shutdown systems typically use equipment that is SIL 2 certified as a minimum, whereas control systems can start with SIL 1. SIL applies to both hardware and software requirements ...
