Spread spectrum communication systems may be affected by other types of signals called outliers. These coexisting signals are typically narrow (or concentrated) in the considered domain. This thesis considers two areas of outlier detection, namely th

Ghrelin is a peptide hormone with anabolic functions. It increases growth hormone secretion and appetite, decreases fat utilisation as a metabolic fuel and increases fat storage in the adipose tissue. In addition, ghrelin exerts effects on glucose me

Quantum algorithms may be described by sequences of unitary transformations called quantum gates and measurements applied to the quantum register of n quantum bits, qubits. A collection of quantum gates is called universal if it can be used to constr

We have measured the influence of shot noise on hysteretic Josephson junctions initially in macroscopic quantum tunnelling (MQT) regime. Escape threshold current into the resistive state decreases monotonically with increasing average current through

Resumo Os rádios cognitivos são considerados fundamentais para melhorar o uso do espectro em redes 5G. O sensoriamento de espectro é uma tecnologia que permite que o estado do canal seja determinado de forma descentralizada. O sensoriamento colabo

Connectivity in remote areas continues to be a major challenge despite of the evolution of cellular technology. 5th Generation (5G) technology can address remote connectivity if lower carrier frequencies are available, which calls for shared use of s
