It classifies five classes: IE1 (standard), IE2 (high) and IE3 (premium), IE4 (super premium efficiency), IE5 (ultra premium efficiency). For each class the efficiency is defined for a rated output range from 0.75 to 375 kW. In the European Community the IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class will be ...
Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency.. As part of a concerted effort worldwide to reduce energy consumption, CO 2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced, or are planning, legislation to encourage the ...
As such, the compiler must also generate "hidden" code in the constructors of each class to initialize a new object's virtual table pointer to the address of its class's virtual method table. Many compilers place the virtual table pointer as the last member of the object; other compilers place it as the first; portable source code works either ...
Most programming languages, compilers and operating systems offer no or little more support than dynamic loading of libraries and late linking, therefore software utilizing dynamic dead-code elimination is very rare in conjunction with languages compiled ahead-of-time or written in assembly language.
A premium efficiency electric motor: more than 90% (see Main Article: Premium efficiency). A large power transformer used in the electrical grid may have efficiency of more than 99%. Early 19th century transformers were much less efficient, wasting up to a third of the energy passing through them.
In compiler theory, common subexpression elimination (CSE) is a compiler optimization that searches for instances of identical expressions (i.e., they all evaluate to the same value), and analyzes whether it is worthwhile replacing them with a single variable holding the computed value.
Beck missed the second half of the game, and backup quarterback Gunner Stockton took over and led the Bulldogs to the win in overtime. That secured them a spot in the College Football Playoff and ...
Link-time optimization (LTO), or whole-program optimization, is a more general class of interprocedural optimization. During LTO, the compiler has visibility across translation units which allows it to perform more aggressive optimizations like cross-module inlining and devirtualization.
