For years, a French mathematician searched for a proof that a gigantic number is prime. His method is still used 150 years ...

Most of us have little trouble working out how many milliliters are in 2.4 liters of water (it's 2,400). But the same can't be said when we're asked how many minutes are in 2.4 hours (it's 144).

Abstract: This study examines the aerodynamic behavior of the low Reynolds number Eppler-E63 airfoil under normal and reverse flow conditions. This airfoil design is commonly used in the propulsion ...

Abstract: The high capacitance requirement becomes a significant problem when modular multilevel converters (MMCs) are applied to medium or low-voltage systems. This paper proposes a capacitor voltage ...
