Accurate portfolio risk-return structure modelling
… GARCH(1, 1) is compared within the volatility modelling extensions of the GARCH environ in a single index framework. This study will demonstrate the persistence of the superiority of the G ARCH ( 1, 1) frontier within a multiple and single index context of modem portfolio theory. Many portfolio …

Enhancing RNA Foundation Models via Secondary Structure Modelling
… by its functional dependence on complex structure. Modelling this intricate sequence-structure-function relationship represents a vital problem in computational biology. This thesis aims to resolve three core impediments to progress in structure-aware RNA Foundation Model (FM). First, the …

Electronic Structure Modelling of Singlet Fission in Organic Photovoltaics
… thesis we employ \emph{ab initio} electronic structure techniques to study the excitations involved in fission in molecular crystals and dimers, using the well-studied pentacene molecule as a reference system. Linear-scaling density functional theory (LS-DFT) is used to model the influence of …

Polynomials and models of type theory
This thesis studies the structure of categories of polynomials, the diagrams that represent polynomial functors. Specifically, we construct new models of intensional dependent type theory based on these categories. Firstly, we formalize the conceptual viewpoint that polynomials are built out of …

Estimation of Shadow-Rate Term Structure Models Near the Zero-Lower Bound
… it is customary to use standard Gaussian term structure models for term structure modelling, this becomes theoretically implausible in cases when nominal interest rates are near zero: Gaussian models can have arbitrarily large negative rates, whereas arbitrage considerations dictate that rates …

A framework for adopting solar energy governance in the Nigerian power sector
… on literature review and findings from the semi-structured interview held with 25 top management officials of solar energy stakeholders in Nigeria. The philosophical position of this research is inductive approach and interpretivist paradigm. The qualitative data collection method was employed, …

Structure, morphology and reaction mechanisms of novel electrode materials for lithium-ion batteries
… of excess Li does not change the average crystal structure; however, it alters the cycling performance greatly. This suggests that the local structure governs the electrochemical behaviour. This motivated us to employ the pair distribution function (PDF) technique to probe the local structure. The …

Zur molekularen Topologie der Bindung natürlicher und rekombinanter Varianten von Alpha 2 -HS-Glycoprotein-Feturin an Hydroxylapatit
… of precipitation was studied by use of structure-function relations of protein domains of the cystatin superfamily. Since no structural data of these cystatin-like domains were available, models were generated by comparative structure modelling. The model of AHSG domain D1 shows an …

Statistical genetics tools for empowered data-driven decisions
… Chapter 2 explores the application of covariance structure modelling in two common scenarios of perennial plant breeding: multi-harvest and multi-site data analysis. Chapter 3 demonstrates the use of factor analytic mixed models in maize breeding, including the incorporation of selection tools for …

Evolution of targets at the host-pathogen interface
… methodologies. Chapter 4: SARS-CoV-2 proteome modelling and drug target assessment <br>In this chapter, I explore the 3D protein structure modelling and functional annotation of overlapping ORFs on the positive- and negative-sense strands of the SARS-CoV-2 genome. The structural implications of …

NMR, Metabonomics and Molecular Profiles: Applications to the Quality Assessment of Foodstuffs
… can be interpreted in terms of molecular structure, conformation, molecular motion and other rate processes. In this way, high resolution (HR) NMR allows performing qualitative and quantitative analysis of samples in solution, in order to determine the structure of molecules in solution …

Multicomponent Complexes, Structural Proteomes, Drug Discovery For Cancer Gene Census And SARS CoV-2
… is expensive and time-consuming, a protein modelling algorithm such as a MODELLER can reduce the ample space between the sequence and structural annotation in less time. Thus, solving protein structures with reliable or high accuracy quality assessment can be achieved computationally. This …

Attributes sanitization in object-oriented design to improve database structure
Modelling using the Entity Relationship Model was introduced more than thirty years ago. Until late 1990’s, object-oriented introduced class diagram. However, designing a good database is still a serious issue. Some of the issues are very difficult to handle such as consistency checking between …
