Automatic Reconstruction of Semantic 3D Models from 2D Floor Plans
Aleixo Cambeiro Barreiro, Mariusz Trzeciakiewicz, Anna Hilsmann +1
Digitalization of existing buildings and the creation of 3D BIM models for them has become crucial for many tasks. Of particular importance are floor plans, which contain informati…
Data-driven Enhancement of the Time-domain First-order Regular Perturbation Model
Astrid Barreiro, Gabriele Liga, Alex Alvarado
A normalized batch gradient descent optimizer is proposed to improve the first-order regular perturbation coefficients of the Manakov equation, often referred to as kernels. The op…
Capacity Bounds for Optical WDM Channels with Peak Power Constraints
Viswanathan Ramachandran, Gabriele Liga, Astrid Barreiro +1
We investigate optical WDM transmission from the standpoint of an information-theoretic interference channel. Achievable rates that outperform treating interference as noise are pr…
Automated Damage Inspection of Power Transmission Towers from UAV Images
Aleixo Cambeiro Barreiro, Clemens Seibold, Anna Hilsmann +1
Infrastructure inspection is a very costly task, requiring technicians to access remote or hard-to-reach places. This is the case for power transmission towers, which are sparsely…
Capacity Region Bounds for the K user Dispersive Nonlinear Optical WDM Channel with Peak Power Constraints
Viswanathan Ramachandran, Gabriele Liga, Astrid Barreiro +1
It is known that fiber nonlinearities induce crosstalk in a wavelength division multiplexed (WDM) system, which limits the capacity of such systems as the transmitted signal power…
A Data-driven Optimization of First-order Regular Perturbation Coefficients for Fiber Nonlinearities
Astrid Barreiro, Gabriele Liga, Alex Alvarado
We study the performance of gradient-descent optimization to estimate the coefficients of the discrete-time first-order regular perturbation (FRP). With respect to numerically comp…
A Capacity Region Outer Bound for the Two-User Perturbative Nonlinear Fiber Optical Channel
Viswanathan Ramachandran, Astrid Barreiro, Gabriele Liga +1
We study a nonlinear fiber optical channel impaired by cross-phase modulation and dispersion from the viewpoint of an interference channel. We characterize an outer bound on the ca…
Modeling of Nonlinear Interference Power for Dual-Polarization 4D Formats
Gabriele Liga, Bin Chen, Astrid Barreiro +1
We assess the accuracy of a recently introduced nonlinear interference model for general dual-polarization 4D formats.~ Unlike previous models for polarization-multiplexed 2D forma…
Extending fibre nonlinear interference power modelling to account for general dual-polarisation 4D modulation formats
Gabriele Liga, Astrid Barreiro, Hami Rabbani +1
In optical communications, four-dimensional (4D) modulation formats encode information onto the quadrature components of two arbitrary orthogonal states of polarisation of the opti…
Quantum Locality in Game Strategy
Carlos A. Melo-Luna, Cristian E. Susa, Andres F. Ducuara +2
Game theory is a well established branch of mathematics whose formalism has a vast range of applications from the social sciences, biology, to economics. Motivated by quantum infor…
