Frequency and Polarization Switched QPSK [PDF]
39th European Conference and Exhibition on Optical Communication (ECOC 2013), 2013 We propose 8-dimensional biorthogonal modulation as a format with 3 dB increased asymptotic power efficiency over PM-QPSK. We demonstrate one possible experimental implementation of this format based on frequency and polarization switching and compare with dual-carrier PM-QPSK and PS-QPSK.

Power Loss Analysis of Solar Photovoltaic Integrated Model Predictive Control Based On-Grid Inverter
Energies, 2020 This paper presents a finite control-set model predictive control (FCS-MPC) based technique to reduce the switching loss and frequency of the on-grid PV inverter by incorporating a switching frequency term in the cost function of the model predictive ...

Large electric-field induced strain in BiFeO3 ceramics [PDF]
, 2011 Large bipolar strain of up to 0.36% (peak-to-peak value) was measured in BiFeO3 ceramics at low frequency (0.1 Hz) and large amplitude (140 kV/cm) of the driving field.

High frequency electronic ballast provides line frequency lamp current [PDF]
, 2001 Most electronic ballasts for fluorescent lamps provide a sinusoidal lamp current at the switching frequency. The high-frequency current flowing through the lamp can generate significant radiated noise, which is unacceptable in noise-sensitive ...

High-frequency switching in Candida albicans [PDF]
Clinical Microbiology Reviews, 1992 Most strains of Candida albicans are capable of switching frequently and reversibly between a number of phenotypes distinguishable by colony morphology. A number of different switching systems have been defined according to the limited set of phenotypes in each switching repertoire, and each strain appears to possess a single system.
