NAT Traversal Techniques and UDP Keep-Alive Interval Optimization
(2015-07)NAT traversal presents a challenge to Peer to Peer (P2P) applications, as in many instances a third party is needed to help initiate communication between two hosts when one is behind one or more NAT devices. Much work has ... -
A Network-Driven Approach for Characterizing Emoji Usage in Social Media
(2019-07)With the rapid growth in the number of online users, people tend to use emojis to enrich their text with emotions. In this dissertation, after an overview of the previous studies on emojis, we provide a brief introduction ... -
New Bounds for the k-out-of-n Type Probabilities and Their Applications
(2017-04)The contribution of the shape information of the underlying distribution in probability bounding problem is investigated and an efficient linear programming based bounding methodology, which takes advantage of the advanced ... -
A Novel Approach to Containerize Existing Applications
(2018-06)Cloud computing has dominated the way different services are offered, utilized and managed over the internet. Typically, applications run inside the virtual machines in an isolated environment. However, there is always ... -
Novel Hyperspectral Imagery and Platforms for Shallow Water Environments
(2017-07)Hyperspectral measurements of the water surface in urban coastal waters are presented. Oblique bidirectional reflectance factor (BRF) imagery was acquired of coastal shallow waters within the watershed of the Indian ... -
Numerical Analysis of a Compact Helical Counterflow Heat Exchanger
(2018-04)The performance of compact counter flow heat exchangers with helically shaped passages is examined using a 1-D analytical model and compared with a high-fidelity 3-D numerical simulation. The 1-D model is capable of ... -
Numerical and Analytical Modelling for Droplet Evaporation Resulting in Convective Flow Cooling Verified by Experimentation
(2018-04)The temperature of a gaseous convective stream can be reduced by injecting a colder liquid into the stream. The extent to which this gas temperature can be reduced depends on the amount of liquid being injected into the ... -
NUMERICAL METHODS FOR EIGENVALUE COMPUTATION OF FOURTH-ORDER SELF-ADJOINT ORDINARY DIFFERENTIAL OPERATORS
(2019-01)This dissertation is mainly concerned with three new and very different numerical methods for computing eigenvalues of fourth-order Sturm-Liouville differential operators on finite intervals with regular boundary conditions. ... -
Numerical Modeling of Phase Transition in Shock Tube Problem
(2019-12)In this work, we developed a numerical model for phase transition in shock-tube problem. This work focused on simulating shock-tube problem and the numerical framework is based on a two-phase flow model. Our simulation ... -
Numerical modeling of soy biodiesel to maximize engine power and efficiency while minimizing pollutant emissions
(2016-07)Biodiesel is a renewable fuel that can help to reduce dependence on foreign petroleum and to help control the negative environmental effects of combustion engines. This work develops a numerical model for soy biodiesel ... -
Numerical Study of Erosion of the Internal Wall of Sales Gas Piping by Black Powder Particles
(2016-12)Micro particles, primarily from iron, can wreak havoc on a Sales Gas System. For example, the transport of particles with the gas flow can cause erosion damage to the piping system, lead to the release of toxic gasses, ... -
Numerical Study on Seakeeping Performance of Hydrofoil Assisted Submersible Trimaran (HAST)
(2019-03)The present study focuses on the seakeeping characteristics of Hydrofoil Assisted Submersible Trimaran (HAST). The seakeeping performance is an important part in ship design because it effects the comfort, control, ... -
Object matching using the dynamic programming algorithm
(1997-03)A new algorithm for matching objects between images is developed and investigated. Affine transformations, i.e. those with translation, rotation, scaling and shearing between images are considered. Steps along the way include ... -
On Logconcavity of Multivariate Discrete Distributions
(2017-12)The contribution of this dissertation to the literature is twofold. First, we use a geometric perspective to present all possible subdivisions of R³ into tetrahedra with disjoint interiors and adopt a combinatorial ... -
On Phase Change Material Heat Exchangers: A Computational and Experimental Investigation
(2016-10)The emergence of ground- and airborne-based high energy laser (HEL) weapon systems has created a need for high-rate thermal energy storage (TES) devices that meet demanding size, weight, and power (SWaP) requirements for ... -
On the Automation of Cyber Experimentation
(2018-06)There are a variety of tools available to users to perform cyber experimentation, and many of them automate some aspects of the experimentation lifecycle. However, they either support a minimal subset of the tools across ... -
On the Classification of the Second Minimal Orbits of the Continuous Endomorphisms on the Real Line and Universality in Chaos
(2017-04)This dissertation presents full classification of second minimal odd periodic orbits of a continuous endomorphisms on the real line. A (2k + 1)-periodic orbit (k ≥ 3) is called second minimal for the map f, if 2k−1 is a ... -
