Research Directions in Network Service Chaining
Wolfgang John, Kostas Pentikousis, George Agapiou +7
Network Service Chaining (NSC) is a service deployment concept that promises increased flexibility and cost efficiency for future carrier networks. NSC has received considerable at…
Canonical polyadic decomposition of third-order tensors: reduction to generalized eigenvalue decomposition
Ignat Domanov, Lieven De Lathauwer
Canonical Polyadic Decomposition (CPD) of a third-order tensor is decomposition in a minimal number of rank- tensors. We call an algorithm algebraic if it is guaranteed to find…
A multi-level preconditioned Krylov method for the efficient solution of algebraic tomographic reconstruction problems
Siegfried Cools, Pieter Ghysels, Wim van Aarle +2
Classical iterative methods for tomographic reconstruction include the class of Algebraic Reconstruction Techniques (ART). Convergence of these stationary linear iterative methods…
Multi-Structural Signal Recovery for Biomedical Compressive Sensing
Yipeng Liu, Maarten De Vos, Ivan Gligorijevic +3
Compressive sensing has shown significant promise in biomedical fields. It reconstructs a signal from sub-Nyquist random linear measurements. Classical methods only exploit the spa…
The near shift-invariance of the dual-tree complex wavelet transform revisited
Adriaan Barri, Ann Dooms, Peter Schelkens
The dual-tree complex wavelet transform (DTCWT) is an enhancement of the conventional discrete wavelet transform (DWT) due to a higher degree of shift-invariance and a greater dire…
Intrinsicness of the Newton polygon for smooth curves on
Wouter Castryck, Filip Cools
Let be a smooth projective curve in of genus , and assume that it is birationally equivalent to a curve defined by a Laurent polynomi…
