A review of multi-chamber oscillating water column(OWC)device designs is presented.Two significant variations of these devices are discussed,onshore OWC(OOWC)and a floating OWC(FOWC).The efficiency results of several ...
A root system is any collection of vectors that has properties that satisfy the roots of a semi simple Lie algebra. If g is semi simple, then the root system A, (Q) can be described as a system of vectors in a Euclide...
