A mathematical analysis of marine size spectra
… spectrum’), follows a power law and this has mathematically been explained by the processes of growth and mortality primarily driven by predation. In this theory of the size spectrum, predation is driven by body size: as organisms grow bigger the size of their prey also increases. This process …

Mathematical analysis of a dynamical system for sparse recovery
This thesis presents the mathematical analysis of a continuous-times system for sparse signal recovery. Sparse recovery arises in Compressed Sensing (CS), where signals of large dimension must be recovered from a small number of linear measurements, and can be accomplished by solving a complex …

Mathematical Analysis of Compressive/Tensile Molecular and Nuclear Structures
Mathematical analysis in chemistry is a fascinating and critical tool to explain experimental observations. In this dissertation, mathematical methods to present chemical bonding and other structures for many-particle systems are discussed at different levels (molecular, atomic, and nuclear). …

Mathematical Analysis on the PEC model for Thixotropic Fluids
… to as thixotropy. This dissertation establishes mathematical analysis on a thixotropic yield stress fluid using a viscoelastic model under the limit that the ratio of retardation time versus relaxation time approaches zero. The differential equation model (the PEC model) describing the evolution …

Mathematical analysis of a large-gap electromagnetic suspension system
In a form of controlled electromagnetic suspension, a permanent magnetic is levitated by a magnetic field; the field is produced by electrical currents passing through coils. These currents are the control input. In a Large-Gap system the coils are at some distance from the suspended body; in …

A mathematical analysis of evolutionary rescue and niche construction
Laboratory experiments and field studies have shown that declining populations can avoid extinction by undergoing adaptation. This process, evolutionary rescue, entails a population approaching extinction until an adaptive mutation appears and subsequently establishes by escaping stochastic loss. …

Mathematical analysis of fractional-order chemostat model with time delay
The fractional-order differential equations (FDEs) is studied to describe the dynamic behaviour of a chemostat system. This study also investigated the FDEs with time delay to examine the effect of time delay on the behaviour of a chemostat system. The integer-order chemostat model in the form of …

Mathematical analysis of uncertainty in machine learning and deep learning
… in machine learning and deep learning from the mathematical point of view. Uncertainty is involved in many real-world situations. The Bayesian modelling can handle such uncertainty in machine learning community. However, the traditional deep learning model fails to show uncertainty for its …

Techniques for mathematical analysis and optimization of agent-based models
… Given that agent-based models have no rigorous mathematical formulation, standard analysis is difficult, and traditional mathematical approaches are often intractable. This work presents techniques for the analysis of agent-based models and for solving optimization problems with such models. …

Mathematical Analysis of Upscaling Well Log Data from Sonic to Seismic Resolution
… upscaling methods. In conclusion, from a mathematical perspective the results for the Pythagorean means are different. However, the geophysical application of the means in upscaling well log data yields results with differences that fall within the margin of error. The results of the …
