Sufficient stochastic maximum principle in a regime-switching diffusion model [PDF]

, 2010
We prove a sufficient stochastic maximum principle for the optimal control of a regime-switching diffusion model. We show the connection to dynamic programming and we apply the result to a quadratic loss minimization problem, which can be used to solve a

Quantifying Incomplete Zero-Voltage Switching Losses Using Equivalent Hard-Switching Losses

With fast switching wide band-gap semiconductors conquering high-power application, zerovoltage switching (ZVS) topologies are crucial toincrease converter efficiency by minimizing switchinglosses. However, ZVS criteria cannot always be fulfilledin the entire operating range of the converter.

No-Switching Quantum Key Distribution using Broadband Modulated Coherent Light [PDF]

, 2005
We realize an end-to-end no-switching quantum key distribution protocol using continuous-wave coherent light. We encode weak broadband Gaussian modulations onto the amplitude and phase quadratures of light beams at the Shannon's information limit. Our no-
