Power system adequacy: on twoarea models and the capacity procurement decision process
(The University of Edinburgh, 20230120)In this work, we explore methodological extensions to modelling practices in power system adequacy for singlearea and twoarea systems. Specifically, we build on top of some of the practices currently in use in Great ... 
Conditional densities of partially observed jump diffusions
(The University of Edinburgh, 20230119)In this thesis, we study the fi ltering problem for a partially observed jump diffusion (Zₜ)ₜɛ[ₒ,T] = (Xₜ, Yₜ)tɛ[ₒ,T] driven by Wiener processes and Poisson martingale measures, such that the signal and observation noises ... 
DonaldsonThomas theory and cohomological Hall algebras of character stacks
(The University of Edinburgh, 20230118)Given a smooth finitely generated algebra with a potential one can study the refined DonaldsonThomas theory of its moduli stack of representations via motivic or cohomological methods. In this thesis we focus on fundamental ... 
Presolve, crash and software engineering for HiGHS
(The University of Edinburgh, 20230118)The efficient computational solution of linear optimization problems is generally enhanced significantly by using a "presolve" procedure to process the problem logically in order to reduce the dimension of the problem to ... 
Optimising heating and cooling of smart buildings
(The University of Edinburgh, 20230110)This thesis is concerned with optimization techniques to improve the efficiency of heating and cooling of both existing and new buildings. We focus on the thermal demandside and we make novel contributions to the ... 
Spatial and temporal hierarchical decomposition methods for the optimal power flow problem
(The University of Edinburgh, 20230109)The subject of this thesis is the development of spatial and temporal decomposition methods for the optimal power flow problem, such as in the transmissiondistribution network topologies. In this context, we propose novel ... 
Accelerating Bayesian computation in imaging
(The University of Edinburgh, 20221219)The dimensionality and illposedness often encountered in imaging inverse problems are a challenge for Bayesian computational methods, particularly for stateoftheart sampling alternatives based on the EulerMaruyama ... 
Bayesian analysis of jointly heavytailed data
(The University of Edinburgh, 20221129)This thesis develops novel Bayesian methodologies for statistical modelling of heavytailed data. Heavy tails are often found in practice, and yet they are an Achilles heel of a variety of mainstream random probability ... 
Size and shape of things: magnitude, diversity, homology
(The University of Edinburgh, 20221129)This thesis has to do with magnitude: a numerical invariant of enriched categories which, when specialized to examples such as posets, groupoids or metric spaces, turns out to encompass a variety of sizerelated quantities ... 
Pretrained solution methods for unit commitment
(The University of Edinburgh, 20221116)This thesis aims to improve the solution methods for the unit commitment problem, a shortterm planning problem in the energy industry. In particular, we focus on DantzigWolfe decomposition with a column generation ... 
On the dynamics of measure flows and multiagent and meanfield financial games
(The University of Edinburgh, 20221124)This thesis comprises two different collection of results. We present several ItôWentzell formulae on Wiener spaces for realvalued functional random field of Itô type that depends on measure flows. We distinguish the ... 
Optimal coordination of multiple pricemaker electricity storage units for price arbitrage
(The University of Edinburgh, 20221011)Decarbonization of the electricity supply via the integration of renewable generation poses significant challenges for electric power systems, but also creates new market opportunities. Electric energy storage can take ... 
Stability, Hilbert scheme and PT moduli of genus four curves and failure of the MMP/Wallcrossing correspondence
(The University of Edinburgh, 20221124)Inspired by concepts in string theory, the notion of stability conditions on triangulated categories was introduced by Bridgeland in 2002. Its impact across mathematics includes the solutions of classical problems in ... 
Change detection in spatiotemporal SAR data for deforestation monitoring
(The University of Edinburgh, 20220822)Forests play a vital role in the wellbeing of our planet. Large and small scale deforestation across the globe is threatening the stability of our climate, forest biodiversity, and therefore the preservation of fragile ... 
Preconditioned iterative methods for optimal control problems with timedependent PDEs as constraints
(The University of Edinburgh, 20220627)In this work, we study fast and robust solvers for optimal control problems with Partial Differential Equations (PDEs) as constraints. Speci cally, we devise preconditioned iterative methods for timedependent PDEconstrained ... 
Bayesian analysis of nonstationary extremes
(The University of Edinburgh, 20220627)Extreme value theory (EVT) provides theoretical foundation to assess the probability of rare and extreme events. This thesis provides novel Bayesian semiparametric models for capturing the behaviour of extreme events and ... 
Role of structure in oscillatory integral estimates
(The University of Edinburgh, 20220622)Although oscillatory integrals intrinsically depend only on measuretheoretic properties of the phase and amplitude functions, in practice most techniques for deriving estimates invoke structural information either implicitly ... 
Stochastic dynamics and partitioned algorithms for model parameterization in deep learning
(The University of Edinburgh, 20220616)In this thesis, we study model parameterization for deep learning applications. Part of the mathematical foundation for this work lies in stochastic differential equations and their constrained counterparts. We will study ... 
Local and global analysis of geometric partial differential equations and their application to curvature flow problems
(The University of Edinburgh, 20220615)“An analytical approach to many problems in geometry leads to the study of partial differential equations.” (A. V. Pogorelov, Foreword to The Minkowski Multidimensional Problem) This thesis concerns itself with three ... 
Uncertainty quantification in seismic interferometry
(The University of Edinburgh, 20220613)It is a wellestablished principle that crosscorrelating wavefield observations at different receiver locations yields new responses that, under certain conditions, provide a useful estimate of the Green's function between ...
