Contributions to the Model Theory of Fields and Compact Complex Spaces
… in the natural language of their analytic sets. The notion of a Zariski closed set in an elementary extension of a compact complex space, as well as the associated complex dimension, are discussed. It is shown that a one-dimensional Zariski closed set in an elementary extension of a compact …

On the convexity of right-closed sets and its application to liveness enforcement in Petri Nets
A set of n-dimensional integral vectors, Nn, is said to be right-closed if for any x 2 , any vector y x also belongs to it. An integral-set Nn is convex if and only if there is a convex set C Rn such that = Int(C), where Int( ) denotes the integral points in the set argument. In this dissertation, …

Outcomes of Auditory Brainstem Implantation in Adults with Postlingual Deafness: A Systematic Review
… the measures have been categorized as either closed-set (CS) or open-set (OS). Total overall sample size across the 13 included studies was 170. Of the 170 participants, 91 (54%) were adults with postlingual deafness; 76 participants (84%) were adults with NF2, and 15 participants (16%) were …

Algorithms for computing liveness enforcing supervisors for discrete event-driven systems modeled by petri nets
… an LESP can be effectively represented by a set of initial markings for which an LESP exists. We restrict our attention to certain classes of PN structures for which the aforementioned set is known to be right-closed. A set of non-negative integral vectors is said to be right-closed if the …

Some Results on G-Delta Ideals of Compact Sets
… broad natural class of Gdelta ideals of compact sets on E, called Gdelta ideals with property (*), and has shown that any ideal I in this class can be represented through the ideal of nowhere dense subsets of a closed subset F of the hyperspace of compact subsets of E. In this thesis we show that …

Negative answers to some positivity questions
… base locus of a divisor is not always a closed set; Zariski decompositions do not necessarily exist in dimension three; asymptotic multiplicity invariants are not always finite in the relative setting; and the number of Fourier- Mukai partners of a variety can be infinite.

An Ai-Powered 3-D Facial Recognition Framework for Crime Intelligence using Reconstructive and Predictive Techniques
… an LDA-reduced 256-D version and tests using closed set identification, verification ROC, robustness and explainability tools (Grad-CAM, region occlusion). Nevertheless, a comparison suite is provided where these embeddings are compared to Buffalo InsightFace features using k-NN …

Counting with convolutional neural networks
… there? To study this, we create a synthetic dataset consisting of black and white images with variable numbers of white triangles on a black background, oriented right-side up, down, left or right. We train a network to count the right-side up triangles; specifically, we see this as a closed-set …

Social identity in Shakespeare's plays : a quantitative study
… (Anthony 2014) and Ubiqu+ity can be applied to a closed-set collection of plays understood to be written by Shakespeare (Wells and Taylor 1987, 109-134) to test claims laid out by literary critics. This thesis therefore shows how quantitative evidence can lead to a more complex and robust analysis …

Object-Oriented Implementation of the minimally restrictive liveness enforcing supervisory policy in a class of Petri nets
… is directly related to the presence of a right-closed set of states that are control invariant with respect to the system. A minimally restrictive LESP prevents the occurrence of events in a DEDS system only when it is absolutely necessary. This study describes an object-oriented implementation …

Geometry of Ricci-flat Kähler manifolds and some counterexamples

Deep Neural Networks for Multi-Source Transfer Learning
… and fuzzy rule-based model are explored under closed-set, partial and open-set settings. Finally, universal domain adaptation is exploited by designing a model which is flexible enough to multiple source domains with homogeneous and heterogeneous label spaces.

Zeros of partial sums of power series
… partial sums is investigated. We prove that the set of limit points of xeros of partial sums of rational functions can contain an open disk outside the unit circle, while that of a power series with the unit circle as its natural boundary can be empty outside the unit circle. We also prove that, …

General properties of real-valued functions
… of real continuous functions defined on the closed interval [0,1] on the real line have been studied in the past. The present work started with a review of some known analytical results of this class C. An extended class A of positively continuous functions was then defined and its properties …

Modelling out-of-vocabulary words for robust speech recognition
… is constructed and then used to augment the closed-vocabulary search space of a standard speech recognizer. This OOV model achieves open-vocabulary recognition through the use of more flexible subword units that can be concatenated during recognition to form new phone sequences corresponding …

Deep Emotion Analysis of Personal Narratives
… NLP task is the classification into predefined closed-set emotion categories (e.g. happy, sad), or alternatively labels (positive, negative). A deep and fine-grained emotion analysis would require explanations of the trigger events that may have led to a user state. This type of analysis is …

Underwater Semantic Simultaneous Localization and Mapping
… due to the lack of large labeled underwater datasets and the challenging sensor modalities specific to underwater environments. To address these shortcomings, this thesis develops a range of methodologies to advance underwater semantic SLAM capabilities. First, self-supervised learning and visual …

Modeling Errors in Biometric Surveillance and De-duplication Systems
