    Abstract : Managing consistency is a major concern in the design of complex engineering systems. At times, inconsistencies may lead to wrong decisions, resulting in design flaws which can compromise safety and cause failures. One cannot forget the 1999 NASA unmanned MARS Climate Orbiter, which was destroyed due to use of inconsistent units by design teams. READ MORE

  5. 3. Optimization of LDMOS Transistor in Power Amplifiers for Communication Systems
