Reasoning about quantities in natural language
… reasoning involves understanding the use of quantities and numeric relations in text, and reasoning with respect to them. It forms an essential part of everyday interaction. However, little work from the Natural Language Processing community has focused on quantitative reasoning. In this …

Optimizing replenishment order quantities in uncoordinated supply chains
… sizes, production rates, and replenishment order quantities, the inventory cost function exhibits a non-differentiable step-wise convex behavior. Further, the steps are observed to occur at integer ratios of Q and the buyer's production batch. This behavior makes it difficult to analytically …

Improving Separation of Signals from Multiple Physical Quantities Detected by Sensor Arrays
… a mixture of responses to multiple physical quantities. In these applications, it may be helpful to be able to separate this mixture of responses into the signals resulting from the individual sources. This is similar to the cocktail party problem posed with Independent Component Analysis …

Synthesis and spectroscopy studies of fullerenes and discovery of macroscopic quantities of doped fullerenes
… bands. The first method to produce macroscopic quantities of internal metal-doped fullerenes was developed successfully and improved. Lanthanum-doped fullerenes were produced by laser vaporization of a lanthanum oxide/graphite composite rod in a flow of argon at 1200$\sp\circ$C. Many properties …

Incremental Quantities Based Permissive Overreaching Transfer Trip Scheme for Protecting Inverter-Based Renewable Resources
<p>The power generation landscape evolves, with the increase of inverter-based resources (IBRs) such as solar photovoltaics and wind turbines, providing sustainable and clean energy sources. The shift towards IBRs mitigates climate change, creating considerable challenges to traditional power …

Effectiveness of using hand-held calculators for learning decimal quantities and the metric system
The problem of this research was to determine whether using hand-held calculators was more effective for the acquisition and retention of concepts and skills on decimal algorithms and metric units than the use of pencil and paper computation only. The sample consisted of six intact sixth grade …

Identification and evolution of quantities of interest for a stochastic process view of complex space system development
… is driven by measurable characteristics called quantities of interest. These quantities of interest collectively describe the state of system development and evolve as the system matures. This thesis provides context for the contributions of quantities of interest to a stochastic process view of …
