Redundant Gabor frames admit an infinite number of dual frames, yet only the canonical dual Gabor system, con- structed from the minimal l2-norm dual window, is widely used. This window function however, might lack desirable properties, such as good time-f ...
Conjugated kinetic and thermodynamic modeling is suggested as a suitable approach to identify a novel process window (NPW) for the intensification of slow reversible reactions. The aqueous Kolbe-Schmitt synthesis of beta-resorcylic acid is taken as a model ...
Natural selection drives populations towards higher fitness, but crossing fitness valleys or plateaus may facilitate progress up a rugged fitness landscape involving epistasis. We investigate quantitatively the effect of subdividing an asexual population o ...
We consider chains of random constraint satisfaction models that are spatially coupled across a finite window along the chain direction. We investigate their phase diagram at zero temperature using the survey propagation formalism and the interpolation met ...
This dissertation is dedicated to the application of digital holography methods to second harmonic generation microscopy, and to the development of the resulting imaging technique: holographic second harmonic generation microscopy. Second harmonic generati ...
The principal aim of this thesis is to gain a better understanding of the competition between magnetic and quadrupolar degrees of freedom on two-dimensional lattices. Recent experimental investigations of the material NiGa2S4 revealed several anomalous pro ...
Averaging network is adopted to reduce the front-end amplifier's offset in the flash analog-to-digital converter (ADC) commonly at the cost of the boundary threshold error. Such error worsens the integral-nonlinearity and introduces distortion. An averagin ...
Processing of electroencephalographic (EEG) signals has mostly focused on analysing correlates that are time-locked to an observable event. However, when the signal is acquired in less controlled environment, like in the context of a brain-computer interfa ...
This paper presents a novel reading algorithm for an ironless inductive position sensor which exhibits immunity to single-frequency interference (both for high and low frequency signals). This algorithm is based on the three-parameter sine fitting, whose p ...
We propose a transform for signals defined on the sphere that reveals their localized directional content in the spatio-spectral domain when used in conjunction with an asymmetric window function. We call this transform the directional spatially localized ...
