A Domain-Specific Language For Accounting, Janhavi Doshi Aug 2024

A Domain-Specific Language For Accounting, Janhavi Doshi

Theses

Accounting can be loosely described as a set of rules and best practices for recording and reporting financial transactions. Despite the seemingly straightforward nature of these principles, implementing them through programming has proven to be complex. Currently, over 550 accounting software solutions exist, developed using more than 17 programming languages. These diverse and often fragmented solutions have led to numerous instances of fraud and errors that elude early detection due to inadequate validity checks. This study investigates the need for a unified approach by developing a Domain-Specific Language (DSL) for Accounting. The proposed DSL aims to standardize accounting practices, enhance …

Energetics And Passivation Of Surface Defects In Hgte Colloidal Quantum Dots, Jacob D. Eisensmith Aug 2024

Energetics And Passivation Of Surface Defects In Hgte Colloidal Quantum Dots, Jacob D. Eisensmith

Theses

Colloidal quantum dots (CQDs), and especially HgTe CQDs, have the potential to disrupt traditional solid-state manufacturing of sensitive infrared photodetectors. Here we produce a surface model for (111) HgTe surfaces present in tetrahedral CQDs and attempt to use density functional theory (DFT) to explore various issues in the fabrication and performance of HgTe CQD photodetectors. One such concern is the presence of mid-gap trap states that can hurt device performance. In this work, we demonstrate that an abundant source of these trap states is unpassivated mercury at the surface of the nanocrystal, which can be corrected with passivation procedures. Furthermore, …

General Relativistic Magnetohydrodynamics Simulations Of Outflows From Long-Lived Binary Neutron Star Merger Remnants, Allen Wen Aug 2024

General Relativistic Magnetohydrodynamics Simulations Of Outflows From Long-Lived Binary Neutron Star Merger Remnants, Allen Wen

Theses

While the landmark multimessenger observations associated with the binary neutron star (BNS) merger GW170817 confirmed the existence of merging BNS systems and their ability to generate gamma-ray bursts and kilonova emission, the exact physical processes that link hydrodynamics in the merger remnant to electromagnetic (EM) signals remains up for debate. Moreover, the uncertain lifetime of the remnant before its possible collapse to a black hole can dramatically change the physics involved in the postmerger evolution. We aim to facilitate and study energetic outflow launching in the long-lived hypermassive or supramassive neutron star remnant case by performing 3D general relativistic magnetohydrodynamics …


Inference On Neutron Star Parameters And The Nuclear Equation Of State With Rift, Using Prior Eos Information, Askold Vilkha Jul 2024

Inference On Neutron Star Parameters And The Nuclear Equation Of State With Rift, Using Prior Eos Information, Askold Vilkha

Theses

One of the most extreme objects in the Universe, neutron stars are the remnants of supernova explosions. A usual neutron star has a mass in the range of 0.8 − 2.4M⊙ and a radius of about 10 km. Such small radii and high masses imply extreme densities, that exceed the nuclear density ρnuc . The extreme conditions of cold ultradense matter present inside the neutron star cannot be achieved in terrestrial laboratories, so the equation of state (EOS) of such matter is not well understood. Currently, there are many theoretical models of the EOS based on nuclear physics (Quantum Chromodynamics …

Geo-Slam: Using Geometric Hierarchies To Support Localization And Mapping In Forest Environments, Daniel Castellarin Jul 2024

Geo-Slam: Using Geometric Hierarchies To Support Localization And Mapping In Forest Environments, Daniel Castellarin

Theses

Robust mapping and localization can be challenging in environments like forests where easily observable landmarks are virtually indistinguishable from each other. In such environments, GPS or robot odometry may also be compromised by the landscape, tree cover, or method of locomotion. Prior work discussed a method for creating geometric hierarchies to describe the relative positions of unlabeled landmarks. Notably, the polygons from these hierarchies were used to perform accurate place recognition from observations containing partial overlap and sensor noise. Here, we use geometric hierarchies to perform robust data association for collections of virtually identical 2D landmarks in direct support of …
