Noether symmetries in Interacting Quintessence Cosmology [PDF]
arXiv, 2019 The Noether Symmetry Approach is applied to interacting quintessence cosmology with the aim to search for exact solutions and select scalar-field self-interaction potentials. It turns out that the solutions found are compatible with the accelerated expansion of the Universe and with observational dataset, as the SNeIa Pantheon data.

Cyanate Ester and Phthalonitrile Impregnated Carbon Ablative TPS [PDF]
Phenolic resin has extensive heritage as a TPS (Thermal Protection Systems) material, however, alternative resin systems such as Cyanate Ester and Phthalonitrile may offer improved performance compared to state-of-the-art phenolic resin.

The Complexity of Computing a Cardinality Repair for Functional Dependencies [PDF]
arXiv, 2017 For a relation that violates a set of functional dependencies, we consider the task of finding a maximum number of pairwise-consistent tuples, or what is known as a "cardinality repair." We present a polynomial-time algorithm that, for certain fixed relation schemas (with functional dependencies), computes a cardinality repair.

A linear programming approach to the tracking of partials [PDF]
arXiv, 2019 A new approach to the tracking of sinusoidal chirps using linear programming is proposed. It is demonstrated that the classical algorithm of McAulay and Quatieri is greedy and exhibits exponential complexity for long searches, while approaches based on the Viterbi algorithm exhibit factorial complexity. A linear programming (LP) formulation to find the
