Autonomous Object Collecting And Depositing Robot, Erik Anderson

Honors College Theses

The Institute of Electrical and Electronics Engineers (IEEE) hosted SoutheastCon 2019, with one of the conference’s focuses being a robotics competition. The robotics competition simulates the task of removing space debris near a space station and depositing it in predetermined areas. This task must be completed by an autonomous robot that meets a variety of physical design criteria. The performance of robots is measured by means of points, wherein accomplishing positive tasks earns points and vice versa, and the robot that most consistently scores points wins.

In response to the competition, the four engineering physics majors created a robot that …

An Aco-Inspired, Probabilistic, Greedy Approach To The Drone Traveling Salesman Problem, Jessica Houseknecht

Senior Honors Theses

In recent years, major companies have done research on using drones for parcel delivery. Research has shown that this can result in significant savings, which has led to the formulation of various truck and drone routing and scheduling optimization problems. This paper explains and analyzes a new approach to the Drone Traveling Salesman Problem (DTSP) based on ant colony optimization (ACO).

The ACO-based approach has an acceptance policy that maximizes the usage of the drone. The results reveal that the pheromone causes the algorithm to converge quickly to the best solution. The algorithm performs comparably to the MIP model, CP …

Investigation Of Properties Alternation During Super-Critical Co2 Injection In Shale, Sai Wang, Kouqi Liu, Juan Han, Kegang Ling, Hongsheng Wang, Bao Jia

Petroleum Engineering Faculty Publications

The low recovery of oil from tight liquid-rich formations is still a major challenge for a tight reservoir. Thus, supercritical CO2 flooding was proposed as an immense potential recovery method for production improvement. While up to date, there have been few studies to account for the formation properties' variation during the CO2 Enhanced Oil Recovery (EOR) process, especially investigation at the micro-scale. This work conducted a series of measurements to evaluate the rock mechanical change, mineral alteration and the pore structure properties' variation through the supercritical CO2 (Sc-CO2) injection process.

The Detection And Prevention Of Cascading Failure In Power Systems: A Real-Time Solution For Intentional Controlled Islanding, Faycal Znidi

Theses and Dissertations

Intentional controlled islanding (ICI), also referred as controlled system separation or system splitting, has been proposed as an effective corrective control action to help detect, prevent and mitigate the risk and spread of the cascading failures. A practical controlled islanding separation scheme needs to address two critical problems: where to island i.e., the splitting points to form sustainable islands and when to island i.e., Islanding time. This dissertation examines the causes and mechanism of power system cascading outages and develops new approaches to help detect, prevent and mitigate the risk and spread of these cascading failures. Four effective solutions: weighted …

Chemical Technology, Control and Management

The article studies the process of obtaining carbonate-ammonium nitrate (CAN) based on the mixing of melt ammonium nitrate (NH4NO3) with limestone from the Karmana deposit. In this case, the mass ratio of NH4NO3: CaCO3 varied from 100: 5 to 100: 80. For them, the composition, strength, caking capacity, porosity, absorption of dezilnogo fuel, hygroscopic points, sorption capacity and the dissolution rate of the granules were determined. Any amount of limestone flour dramatically reduces caking, porosity, absorption of diesel fuel, increases strength and dissolution rate of nitrate granules. The results of the sorption capacity of the CAN granules show that both …

Cavitation Number As A Function Of Disk Cavitator Radius: A Numerical Analysis Of Natural Supercavitation, Reid Prichard

Senior Honors Theses

Due to the greater viscosity and density of water compared to air, the maximum speed of underwater travel is severely limited compared to other methods of transportation. However, a technology called supercavitation – which uses a disk-shaped cavitator to envelop a vehicle in a bubble of steam – promises to greatly decrease skin friction drag. While a large cavitator enables the occurrence of supercavitation at low velocities, it adds substantial unnecessary drag at higher speeds. Based on CFD results, a relationship between cavitator diameter and cavitation number is developed, and it is substituted into an existing equation relating drag coefficient …

Faculty Publications

Background DNA methylation plays an important role in multiple biological processes that are closely related to human health. The study of DNA methylation can provide an insight into the mechanism behind human health and can also have a positive effect on the assessment of human health status. However, the available sequencing technology is limited by incomplete CpG coverage. Therefore, it is crucial to discover an efficient and convenient method capable of distinguishing between the states of CpG sites. Previous studies focused on identifying methylation states of the CpG sites in single cell, which only evaluated sequence information or structural information. …

Understanding Homework Reviews Through Sentiment Classification, Zachary Mekus

McKelvey School of Engineering Graduate Student Theses & Dissertations

This thesis uses a naive bayes sentiment classifier to analyze six semesters of homework review data from CSE427S. Experiments describe the benefits of an automated classification system and explore original ways of reducing the number of features and reviews. A new algorithm is proposed that tries to take advantage of aspects of the review data that limit classification accuracy. This analysis can be used to help guide the process of automatically using short reviews to understand student sentiment.

On the basis of numerous studies it can be asserted that the modulus of elastic deformation of aging heterogeneous materials rises with increasing t age, approaching the limiting value of the modules of deformation for inhomogeneous material of very old age. The analysis of experimental studies based on the study of aging materials in the most important cases of their loading shows that the creep measure under conditions of natural in homogeneity for any t is a continuous bounded nonnegative function of t for t>t.
