Cleaning up and disposing of approximately 50 years of nuclear waste is the main mission at the U.S. Department of Energy’s Hanford Nuclear Reservation, located in the southeastern part of the state of Washington. A major element of the total cleanup effort involves retrieving, processing, and disposing of radioactive and hazardous waste stored in 177 underground storage tanks. referred to as t...

In countries with hot climates, air-conditioning forms a large proportion of annual peak electrical demand, requiring expansion of power plants to meet the peak demand, which goes unused most of the time. Use of well-designed cool storage can offset the peak demand to a large extent. In this study, an air conditioning system with naturally stratified storage tank was designed, constructed and t...

Valves are usually used in conjunction with large water-tower storage structures. Large pipes carry water from the storage tower to the flush gutter. Valves are used at appropriate locations in the pipeline to control flush water flow to individual gutters. Figure 1 is a schematic layout of a flush system using storage towers, pipelines and valves to flush several gutters. Use of multiple, inte...

This thesis studies methods to solve Visual Question-Answering (VQA) tasks with a Deep Learning framework. As a preliminary step, we explore Long Short-Term Memory (LSTM) networks used in Natural Language Processing (NLP) to tackle Question-Answering (text based). We then modify the previous model to accept an image as an input in addition to the question. For this purpose, we explore the VGG-1...

Let us start by rehearsing some standard definitions. Define the notion of a theory as follows: Definition 1 (Theory) Let A be the axioms of a theory T. The theory of T is the closure of A under semantic consequence, i.e. T = {φ : A φ}. For example, if T is Peano arithmetic, the theory of T is the axioms of Peano arithmetic together with all their semantic consequences. (Obviously , the axioms ...

We describe a computationally reflective object-oriented architecture suitable for incorporating open-ended innovation and emergent entities into simulations. This allows emergent properties to be reified into objects. This requires modifying the model, and the metamodel, by incorporating novel classes and metaclasses dynamically. The classes and metaclasses are modified by including them in th...
