Momentum Dependence of Phase Shifts [PDF]
Physical Review, 1955 A lower limit is found for the momentum derivative of the scattering phase shifts of a relativistic neutral two-particle system when the interaction is of finite range.

Phase-shifting algorithms with known and unknown phase shifts: comparison and hybrid
Optics Express, 2022 The phase-shifting interferometry has been intensively studied for more than half a century, and is still actively investigated and improved for more demanding precision measurement requirements. A proper phase-shifting algorithm (PSA) for phase extraction should consider various error sources including (i) the phase-shift errors, (ii) the intensity ...

Improved Separation of Tone and Broadband Noise Components from Open Rotor Acoustic Data
Aerospace, 2016 The term “open rotor” refers to unducted counter-rotating dual rotors or propellers used for propulsion. The noise generated by an open rotor is very complicated and requires special techniques for its analysis.

Comparison and Validation of Five Modulation Strategies for a Dual Active Bridge Converter
EAI Endorsed Transactions on Energy Web, 2023 This paper addresses the comparison and validation of different modulations for an isolated dc-dc dual active bridge converter (DAB), namely, Duty-Cycle Modulation, Single Phase Shift (SPS), Dual Phase Shift (DPS), Extended Phase Shift (EPS) and Triple ...

2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012 We consider the problem of shape recovery for real world scenes, where a variety of global illumination (inter-reflections, subsurface scattering, etc.) and illumination defocus effects are present. These effects introduce systematic and often significant errors in the recovered shape.

Performance Analysis of Hybrid Phase Shift Keying over Generalized Nakagami Fading Channels
Journal of Telecommunications and Information Technology, 2023 In addition to the benefits of hybrid phase shift keying (HPSK) modulation in reducing the peak to average power ratio of the transmitted signal to reduce the zero cross- ings and the 0◦-degree phase transmissions, HPSK enhances the bit error rate (BER)
