Forward Osmosis Flow Rate Differential Using Different Osmotic Agents, John M. Trzinski
Beyond: Undergraduate Research Journal
Life support is one of the most vital systems flown on manned spaceflight missions. The systems currently used are large, heavy, inefficient, and power consuming in an environment that requires nearly perfect conditions to function. Forward Osmosis (FO) is a form of filtration that uses the natural properties of water and concentration gradients to filter water without the need for any electricity. An experiment was conducted during the Embry Riddle Summer 2018 study abroad to the LUNARES research station in Piła, Poland. This experiment explored how the flow rate of water through a FO filtration system could be affected by …

As more organizations and businesses in different sectors are moving to a digital transformation, there is a steady increase in malware, facing data theft or service interruptions caused by cyberattacks on network or application that impact their customer experience. Bot and Distributed Denial of Service (DDoS) attacks consistently challenge every industry relying on the internet. In this paper, we focus on Machine Learning techniques to detect DDoS attack in network communication flows using continuous learning algorithm that learns the normal pattern of network traffic, behavior of the network protocols and identify a compromised network flow. Detection of DDoS attack will …

Design, Fabrication, And Characterization Of Multilayer Hyperbolic Metamaterials, James Dilts
Graduate Theses - Physics and Optical Engineering
Hyperbolic metamaterials (HMMs) show extreme anisotropy, acting as metals and dielectrics along orthogonal directions. They are designed using the effective medium theory (EMT) and can be fabricated using standard semiconductor processing techniques. Current techniques used to characterize the optical behavior of HMMs have a high complexity or are unable to robustly determine the complex permittivity tensor. We describe the details of a procedure to obtain a very low mean-squared-error (MSE) for extraction of permittivity from hyperbolic metamaterials using spectroscopic ellipsometry. We have verified our procedure by fabricating three different samples of various materials and fill factors designed to have a …

Theses/Capstones/Creative Projects
COMSOL Multiphysics is a simulation software for modeling engineering processes and designs. The software can be used to create applications that allow users to change variables in a model and see the effect on the physics phenomenon under investigation. COMSOL applications can provide an interactive learning experience and help students visualize engineering concepts. This project examines the use of COMSOL to develop applications related to noise control in buildings, focusing on making them useful for education. Two applications were developed based on existing COMSOL models. One simulates sound absorption by a porous foam, and the other simulates sound propagation through …

This work modeled the early to middle successes achieved in the field of ultrafast, high peak power optics, beginning with the work of Nobel Prize winners Donna Strickland and Gérard Mourou in 1985. In our work, 100 fs light pulses of around 800 nm were generated by a Ti:Sapphire oscillator, then amplified to approximately 30 GW peak power using a chirped pulse amplification system that included regenerative and multi-pass amplifiers. As a verification of our pulses having high peak powers and ultrashort durations, they were then used to strike water, glass, and a Kerr Cell. Supercontinuum generation was observed as …

Challenges And Opportunities Of Layered Cathodes Of Linixmnyco(1-X-Y)O2 For High-Performance Lithium-Ion Batteries, Jason Frank
Mechanical Engineering Undergraduate Honors Theses
High energy density lithium-ion batteries (LIBs) are widely demanded for portable electronic devices and electrical vehicles. Layered-structure LiCoO2 oxide (LCO) has been the most commonly used cathode material in commercial LIBs. Compared to LCO, LiNi1-x-yMnxCoyO2 (NMC) cathodes are particularly attractive due to their reduced cost and higher capacity. Among the NMC cathodes, nickel-containing LiNi0.5Co0.3Mn0.2O2 (NMC532) is one of the most promising cathode materials undergoing intensive investigation, but suffers from a series of technical issues, such as structural instability, performance fading, and safety issues. In this …

Design Of Artificial Swarms Using Network Motifs: A Simulation Study, Khoinguyen Trinh
Mechanical Engineering Undergraduate Honors Theses
The objective of this research is to develop a new approach in engineering complex swarm systems with desired characteristics based on the theory of network motifs – subgraphs that repeat themselves (patterns) among various networks. System engineering has traditionally followed a top-down methodology which creates a framework for the system and adds additional features to meet specific design requirements. Meanwhile, complex swarm systems, such as ant colonies and bird flocks, are formed via a bottom-up manner where the system-level structure directly emerges from the interactions and behaviors among individuals. The behaviors of these individuals cannot be directly controlled, which makes …

Electronic Theses and Dissertations
On a scorching summer day in 2015, a campus maintenance worker was observed emptying a trash bin. Upon closer observation, it was noted that the bin was not full; in fact, it was less than one third full. There were other bins that were full and needed to be emptied urgently. It was confusing and problematic to see that bins that needed more attention were not prioritized. After extended research, it was found that maintenance operates on daily routes to pick up trash at designated times, regardless of the level of trash in the bins. Therefore, to tackle this issue, …

Automated Generation Of Daily Evacuation Paths In 4d Bim, Kyungki Kim, Yong-Cheol Lee
Durham School of Architectural Engineering and Construction: Faculty Publications
Spatial movements of workers and equipment should be carefully planned according to project plans. In particular, it is crucial for workers’ safety to prepare emergency evacuation paths according to changing construction site configurations and construction progress. However, creating evacuation paths for all crews for each day can be an extremely labor-intensive task if it is done manually. Consequently, in most construction projects, evacuation plans are not provided to managers and crews throughout the entire construction. Even state-of-the-art technologies do not suggest ways to generate evacuation paths according to changing progresses presented in 4-Dimensional Building Information Model (4D BIM). This research …

Graduate Theses & Non-Theses
Historic placer mining operations along the Middle Fork John Day River (MFJD) north of Galena, Oregon have left the MFJD channel straightened, incised and lacking in riverbed structure. This lack of riverbed structure makes this stretch of the MFJD poor habitat for trout and migrating salmon. In order to restore this stretch of the MFJD to better serve aquatic species, Inter-Fluve Inc. (IF), United States Forest Service (USFS) and The Freshwater Trust (TFT) will be performing restoration to both the MFJD channel as well as Bear Creek, a tributary of the MFJD. The proposed restoration work will consist of re-routing …

Graduate Theses & Non-Theses
Additive manufacturing (AM), or 3D printing, is a layer by layer method for the fabrication of end use parts. Its utilization in the production of metallic materials, while relatively new, is promising as an alternative technique to build custom or small batch parts with much greater agility than traditional manufacturing methods. The laser powder bed fusion (LPBF) AM technique offers a combination of high geometric accuracy and good mechanical properties for a variety of materials even without post-processing. It can do this by adjusting a number of processing parameters including the intensity of the laser and the thickness of the …

This article provides laboratory research data on the analysis of the ash of combustible shale from the Sangruntau deposit and the possibility of their enrichment. Magnetic enrichment of the ash of combustible shale was carried out in order to determine the yield of the magnetic fraction, determine the chemical composition of the products of magnetic separation, determine the extraction and the enrichment factor for the main elements. When gravitational enrichment of the ash of combustible shale gold almost completely goes into the gravity concentrate. Gravitational enrichment of rhenium, vanadium, copper, zinc, uranium does not occur.
