      rakshit, suman; Davies, Tilman; Moradi, Mehdi; McSwiggan, Greg; Nair, Gopalan; Mateu, Jorge; Baddeley, Adrian Wiley (2019-06)
      We propose a computationally efficient and statistically principled method for kernel smoothingof point pattern data on a linear network. The point locations, and the network itself, are convolvedwith a two-dimensional ...
    • closedAccess   Frequency Stability Requirements in Quasi-Integer-Ratio Time-Expanded Phase-Sensitive OTDR 

      Soriano-Amat, Miguel; Martins, Hugo; Durán, Vicente; Fermoso, Pablo; Martin-Lopez, Sonia; Gonzalez-Herraez, Miguel; Fernández Ruiz, María del Rosario IEEE (2023-01-15)
      Time-expanded phase sensitive (TE-ϕ)OTDR is a recently reported technique for distributed fiber sensing that relies on the use of an electro-optic dual frequency comb (DFC) scheme. A distinctive feature of this approach ...
