This thesis will evaluate the possibility of eliminating EPS from the cold chain packaging system by replacing it with Vacuum Insulated Panels in Greenbox to create a sustainable and reusable packaging system. The most widely used packaging materials in the cold chain system have been compared... READ MORE
On secure networks, even sophisticated cyber hackers must perform multiple steps to implement attacks on sensitive data and critical servers hidden behind layers of firewalls. Therefore, there is a need to study these attacks at a higher multi-stage level. Traditional taxonomy of... READ MORE
As interest in online coupons from distributors like Groupon and Living Social have grown, eBay has proposed and built a marketplace. This marketplace is called eBay Local. It is a place where local merchants can post coupons that distributors can bid on the right to... READ MORE
Whether realized or potential there are a multitude of goals that the environmental manager may be working toward achieving. This thesis evaluated the hypothesis that regardless of the operational goal(s) that the environmental manager may be working toward, the ultimate goal is to achieve... READ MORE
Sign language synthesis is a useful tool in addressing many of the issues faced by deaf communities. Sign languages are as different from spoken languages as spoken languages are from each other, and hence deaf persons raised learning sign language are not automatically proficient... READ MORE
We first study systems of N Schwarzschild black holes in a time-symmetric spacelike hypersurface with axial symmetry. Apparent horizons are found by numerically solving a non linear system of 3 coupled ODE's using Mathematica. The location of the apparent horizon is calculated in each system... READ MORE
This study investigated the relationship between the type of material and the concentration of IgA in human milk stored at two temperatures over time. Twelve breastfeeding mothers participated in the study with samples of milk obtained at locations of the participant's preference and transported... READ MORE
Design for Assembly (DFA) is a tool that has been in use for almost 40 years. While it has been a useful design tool, it is not explicitly linked to actual manufacturing line performance. The motivation for this research came from the desire... READ MORE
The theory of continued fractions has applications in cryptographic problems and in solution methods for Diophantine equations. We will first examine the basic properties of continued fractions such as convergents and approximations to real numbers. Then we will discuss a computationally efficient attack on the... READ MORE
Iterated Prisoner's Dilemma is a simple model for the interaction between two self-interested agents who can choose whether or not to cooperate with one another. Many real-world problems can be characterized in terms of the Iterated Prisoner's Dilemma, from the militarization of rival nations to... READ MORE
Polyethylene Terephthalate (PET) is a widely used polymer in the bottling, packaging, and clothing industry. In recent years an increasing global demand for PET has taken place due to the Solar Disinfection (SODIS) process. SODIS is a method of sterilizing fresh water into drinkable... READ MORE
In this paper, we will solve the Hamiltonian constraint describing a curved general relativistic spacetime to find initial data describing how a black hole exists in vacuum. This has been done before by other researchers [Ansorg, 2004], and we will be adapting our... READ MORE
Network analysts are bombarded with large amounts of low level data, posing great challenges for them to differentiate and recognize critical multistage attacks. Multistage attacks are performed by hackers to compromise one or more machines in a network to gradually gain access to critical... READ MORE
We investigate a delay differential equation system version of a model designed to describe finite time population collapse. The most commonly utilized population models are presented, including their strengths, weaknesses and limitations. We introduce the Basener-Ross model, and implement the Hopf bifurcation test to identify whether there... READ MORE
The purpose of this study was to reveal and assess improvements that can be made to the candidate selection process when developing a Corporate Packaging Group in the Medical Device Industry. READ MORE
