I Never Saw the Llightning, Martin Luther! A Compositional Model
… to light best through the use of a working model. <em>l Never Saw the Lightning, Martin Luther!</em> discusses the problems associated with prewriting structure, point of view, and thematic considerations-as well as techniques of editing and unifying the continuity of a manuscript. These …

Opinion Analysis through Constraint Optimisation
… classifi�cation. A previous study shows that a compositional model can be e�ective in sentiment classifi�cation. But such a model has been only applied using hand-crafted composition rules. The need for hand-crafted rules arise when dealing with conflicting polarity values within the same …

Program for Predicting the Densities and Pressure of Invert Elviulsion Muds Under Static Well Conditions
… invert emulsion muds and base fluids. A compositional material balance model was used to predict the densities of synthetic and oil based muds at different temperatures and pressures under static hole conditions. A program for predicting the densities of different synthetic and oil-based …

Neural network architectures for Prepositional Phrase attachment disambiguation
… of construction. This work explores the use of compositional models of meaning in choosing the correct attachment location. The compositional model is defined using a recursive neural network. Word vector representations are obtained from large amounts of raw text and fed into the neural …

Composing Foundation Models for Decision Making
Recent advancements in conditional generative modeling have enabled models like DALLE and GPT-4 to generate high-resolution images and coherent text from brief prompts. However, developing a foundation model for decision-making is hindered by the scarcity and expense of collecting paired visual, …

Compositional modeling of gas injection in tight oil reservoirs
… oil reservoirs. This work developed an improved compositional model and its associated simulator to understand the complex multiphase and multicomponent behaviors during gas injection into tight oil reservoirs. The model accounts for the key physics in tight oil reservoirs, including nanopore …

A semi-empirical approach to modelling well deliverability in gas condensate reservoirs.
… compressibility factor, viscosity, density, compositional pseudo-pressure, and dynamic three phase relative permeability. The study made use of published data bases of experimentally measured gas condensate PVT properties and three phase relative permeability data. The developed correlations …

EOS modeling and reservoir simulation study of Bakken gas injection improved oil recovery in the Elm Coulee field, Montana
… as the area of interest. Static reservoir models featuring the rock property heterogeneity of the Middle Bakken Member were built, and fluid property models were built based on Bakken reservoir fluid sample PVT data. By employing both compositional model simulation and Todd-Longstaff …

Energy Recovery from Oil Sands Reservoirs
… the chamber. The second approach uses a detailed compositional model to exam the time scales for steam and bitumen flow within the depletion chamber. The approach used for multiple steam and multiple bitumen components is novel. The third study examined the instantaneous steam-to-oil ratio …

Component Neural Networks of Morality
… This has resulted in an informal and disjointed model for the neural mechanisms of morality. This dissertation is concerned with more formally identifying neural components and their influences on each other in the context of moral cognition.</p><p>In Chapter 2, I study how the component neural …

Simulation of Multi-Component Gas Flow and Condensation in Marcellus Shale Reservoir
… for two different cases (single well cylindrical model and actual Marcellus shale gas reservoir with heterogeneous porosity and permeability field). Detailed uncertainty analysis of different parameters has a significant impact on implementing the best production strategies such as bottom-hole …

Constraint handling rules. Compositional semantics and program transformation
… Constraint Handling Rules (CHR). It proposes a compositional semantics and a technique for program transformation. CHR is a concurrent committed-choice constraint logic programming language consisting of guarded rules, which transform multi-sets of atomic formulas (constraints) into simpler ones …

Investigation of Nanopore Confinement Effects on Convective and Diffusive Multicomponent Multiphase Fluid Transport in Shale using In-House Simulation Models
… In this research, two in-house simulation models, i.e., a compositionally extended black-oil model and a fully composition model are developed to examine the nano-pore confinement effects on convective and diffusive multicomponent multiphase fluid transport. Meanwhile, the effect of …
