Analytical prediction of the final error due to noise in a ϕ-OTDR system

Luc Thévenaz, Malak Mohamed Hossameldeen Omar Mohamed Galal, Yuting Yang, Li Zhang, Suneetha Sebastian

An analytical expression to estimate the uncertainty on the frequency shift in ϕ-OTDR systems is established and confirmed by actual data. ...

Power Shifts, Emigration, and Population Sorting

Michaël Aklin

We investigate the consequences of a peaceful shift of power from one social group to another. Theoretically, we show that an individual’s decision to stay put or migrate depends on the difference between the political preferences of groups and the change ...

Modulation Considerations for Modular Multilevel Converter Operating with Parallel Branches and Phase-Shifted Carriers

Drazen Dujic, Stefan Milovanovic

The branch paralleling represents one of the available options with regards to the modular multilevel converter power extension. In such a case, the main technical challenge resides in the control domain, whereas a new set of possibilities from the voltage ...

Kinetics of Ion-Exchange Reactions in Hybrid Organic-Inorganic Perovskite Thin Films Studied by In Situ Real-Time X-ray Scattering

Mohammad Ibrahim Dar, Neha Arora

The exchange of ions in hybrid organic inorganic perovskites with the general formula APbX(3) (A = MA, FA; X = I, Cl, Br) is studied in five different systems using in situ real-time grazing incident X-ray diffraction (GIXD). In systems where the organic c ...

A photonic circuit for complementary frequency shifting, in-phase quadrature/single sideband modulation and frequency multiplication: analysis and integration feasibility

Jianqi Hu

A novel photonic integrated circuit architecture for implementing orthogonal frequency division multiplexing by means of photonic generation of phase-correlated sub-carriers is proposed. The circuit can also be used for implementing complex modulation, fre ...
