Latency-constrained low-complexity lattice reduction for MIMO-OFDM systems
Recent studies have investigated lattice-reduction (LR) preprocessing technique for multiple-inputmultiple-output (MIMO) detection. However, if LR is applied to the orthogonalfreq...

Structure-preserving model reduction of complex physical systems
— Port-based network modeling of complex physical systems naturally leads to port-Hamiltonian system models. This motivates the search for structure-preserving model reduction me...

Fragments-based Model Reduction: Some Case Studies
Molecular biological models usually suffer from a dramatic combinatorial blow up. Indeed, proteins form complexes and can modify each others, which leads to the formation of a hug...

Parameterized Complexity Classes under Logical Reductions
Abstract. The parameterized complexity classes of the W -hierarchy are usually defined as the problems reducible to certain natural complete problems by means of fixed-parameter ...
