Developing and evaluating a hybrid wind instrument [PDF]
, 2014 A hybrid wind instrument generates self-sustained sounds via a real-time interaction between a computed excitation model (such as the physical model of human lips interacting with a mouthpiece) and a real acoustic resonator.

Hybrid-excited variable reluctance machines [PDF]
2015 Intl Aegean Conference on Electrical Machines & Power Electronics (ACEMP), 2015 Intl Conference on Optimization of Electrical & Electronic Equipment (OPTIM) & 2015 Intl Symposium on Advanced Electromechanical Motion Systems (ELECTROMOTION), 2015 In this paper, a study on the energy conversion and the consequent torque production mechanism in hybrid excited variable reluctance machines (HEVRMs) is presented. The derived torque expressions of single-phase HEVRMs with different switching strategies show a similarity to that of DC machines (DCMs), wound-field synchronous machines (WFSMs), or ...

Spin induced gigahertz polarization oscillations in vertical-cavity surface-emitting laser devices [PDF]
, 2011 Spin-controlled vertical-cavity surface-emitting lasers (VCSELs) have been intensively studied in recent years because of the low threshold feasibility and the nonlinearity above threshold, which make spin-VCSELs very promising for spintronic devices ...
