It is administered by the West African Examinations Council (WAEC). [1] It is only offered to candidates residing in Anglophone West African countries. The academic school-leaving qualification awarded upon successful completion of the exams is the West African Senior School Certificate .
WAEC Headquarters, Abuja WAEC office, Ogba, Lagos. The West African Examinations Council (WAEC) is an examination board established by law to determine the examinations required in the public interest in the English-speaking West African countries, to conduct the examinations and to award certificates comparable to those of equivalent examining authorities internationally.

The alttype field allows conversion between units of different type, provided each unit is whitelisted to allow the conversion. As at December 2013, the following energy units have alttype = "torque" (the first line consists of different units, while the second line consists of aliases for units in the first line):

MCC (models of the Model Checking Contest): a collection of hundreds of Petri nets originating from many academic and industrial case studies.
In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current.
Power system long-term optimization focuses on optimizing the multi-year expansion and retirement plan for generation, transmission, and distribution facilities. The optimization problem will typically consider the long term investment cash flow and a simplified version of OPF / UC (Unit commitment), to make sure the power system operates in a ...
An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]
Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle. Energy converter is an example of an energy transformation.
