Born Waveform Inversion in Shot Coordinate Domain
… inversion, variable projection algorithm and model extension concept to get a method that can improve the long scale background model updates reliably and efficiently from seismic data. Born waveform inversion is a partially linearized version of full waveform inversion based on Born …

Progress towards an optimized ¹²⁹Xe / ³He Zeeman maser and a test of boost symmetry
… nHz. In the framework of the general Standard-Model Extension, our result provides the first clean test for the fermion sector of the symmetry of spacetime under boost transformations at a level of 10-27 GeV [1]. We also report progress on the optimization and operation of the …

Using K-means clustering to create cost and demand functions that decrease excess inventory and better manage inventory in defense
… the number of parts required. A single period model extension was created based on K-means clustering of the parts according to lead-time and cost. These groupings provided the backbone of the cost functions created in the thesis. A predictive demand function was also created so that the design …

Forcing ℵ1-free groups to be free.
… group G is ℵ1-free in a countable transitive model of ZFC (and thus by absoluteness, in every transitive model of ZFC) if and only if it is free in some generic model extension. We would like to answer the more specific question of when an ℵ1-free group can be forced to be free while …

Modeling Mortality of Loblolly Pine Plantations
… Whole-stand and individual-tree mortality models were developed for loblolly pine plantations throughout its geographic range in the United States. The model for predicting stand mortality were developed using stand characteristics and biophysical variables. The models were constructed …

Structuring lute tablature and MIDI data: Machine learning models for voice separation in symbolic music representations
… and implementation of machine learning models for voice separation in two forms of symbolic music representations: lute tablature and MIDI data. Three modelling approaches are described: MA1, a note-level classification approach using a neural network, MA2, a chord-level regression …

Development of a fatigue tester and material model for flexible heart valve applications
… These tools address the question of how to model the stress-strain behaviour of polymer networks and thermoplastic polyurethanes in particular, as well as how to practically evaluate the durability of the proposed material. A model for polyurethane stress-strain behaviour is proposed, …

Resource scheduling and design of real-time Cyber-Physical Systems in the open system environment
… Regularity-based Resource Partition (RRP) model is an effective strategy to hierarchically partition and allocate resource to each application. Although RRP model is proved to be effective for such system, there is still a gap between the real system design and the model. Extant RRP model …

Assessing GridSim for modeling the global distribution of next-generation astronomy data
… for the simulation project are: a) a network extension claiming realistic network communication; b) an extendable application programming interface because of the Java programming language; c) a datagrid extension that simulates distributed data storage, and tasks for managing the distributed …

Radiative Corrections to and Connections Among Theories With Lorentz Violation and Time-Varying Couplings
<p>Different models containing Lorentz violation are studied in order to explore possible new physics beyond the standard model. In the electromagnetic sector, a time-variation in the fine structure constant &alpha is studied as a possible mechanism to generate Lorentz, CPT and gauge symmetry …

Investigating local ancestry inference models in mixed ancestry individual genomes
… of such individuals, yielding several models that infer the ancestry of every chromosomal segment in admixed individuals (local ancestry). However, new research questions emerged concerning model statistical and biological parameters, as well as the performance of these models across …

Efficient IC statistical modeling and extraction using a Bayesian inference framework
Variability modeling and extraction in advanced process technologies is a key challenge to ensure robust circuit performance as well as high manufacturing yield. In this thesis, we present an ecient framework for device and circuit variability modeling and extraction by combining an ultra-compact …

Extension and verification of the PWM_SA model to incorporate SANI-specific bioprocesses using experimental data from the Hong Kong SANI saline sewage treatment pilot plant.
… resilience. This study extends the Plant Wide Model for South Africa (PWM_SA) by integrating SANI-specific bioprocesses to evaluate its applicability in ad dressing these challenges. The study's primary objectives included adapting the PWM_SA model to incorporate sulfate reduction, autotrophic …

Four Essays on Inventory and Supply Chain Management
… we generalize classic maximin and minimax regret models (Scarf 1958, Perakis and Roels 2008) of the distributionally robust Newsvendor problem, creating data driven models for censored demand (i.e., sales). In particular, we focus on a single-period single-item distributionally robust Newsvendor …
