Access Management Best Practices, Adam Kirk, Chris Van Dyke

Kentucky Transportation Center Research Report

Research has persistently demonstrated that adopting a systematic access management framework improves highway operations and bolsters safety. Many state transportation agencies have adopted formal access management programs to systematize the application of access management techniques, however, the Kentucky Transportation Cabinet (KYTC) been unable to institute such a program due to institutional, regulatory, and political constraints. Recognizing the benefits of judicious access management, the Cabinet asked researchers at the Kentucky Transportation Center (KTC) to identify access management best practices that are effective, can be easily implemented, and are compatible with existing statutes and regulations. After reviewing national-level and state-level guidance on …

Low Flow Testing, Daniel J. Howes

BioResource and Agricultural Engineering

In arid environments, streamflow enhancement in low flow channels is common. It is challenging to assess enhancement project effectiveness in these channels because of uncertainties in metering (regarding both meters and procedures). The basic equation for flow is:

Q = VA (Eq. 1)

Where,

Q = channel flow rate (e.g., cubic feet per second, CFS)

V = cross sectional average velocity (e.g., feet per second, fps)

A = cross sectional area (e.g., square feet, ft2)

There are three main factors that impact flow measurement uncertainty in natural channels:

1. Flow meter velocity measurements (V)

2. Depth and area measurements (A) …

Graphene-Based Water Desalination Using Atomistic Simulations, Thanh Chinh Nguyen

Mechanical Engineering Research Theses and Dissertations

My research focused on investigating saltwater transport through nanoporous graphene membranes using molecular dynamics (MD) simulations. Particularly, in this dissertation, we focused on pressure-driven flows of salt water through uncharged and charged nanoporous graphene membranes for water desalination applications. In the first study, desalination performance of uncharged single-layer nanoporous graphene membranes was observed based on volumetric flow rate, required pressure drop, and salt rejection efficiency. A functional relationship between the volumetric flow rate, pressure drop, pore diameter, and the dynamic viscosity of saltwater was also examined. In further studies, transport of salt ions through positively and negatively charged single-layer nanoporous …

Generalized Relay Network Design And Collaborative Dispatching In Truckload Transportation, Amin Ziaeifar

Operations Research and Engineering Management Theses and Dissertations

The truckload industry faces a serious problem of high driver shortage and turnover rate which is typically around 100\%. Among the major causes of this problem are extended on-the-road times where drivers handle several truckload pickup and deliveries successively; non-regular schedules and get-home rates; and low utilization of drivers dedicated time. These are by-and-large consequences of the driver-to-load dispatching method, which is based on point-to-point dispatching or direct shipment from origin-to-destination, commonly employed in the industry. In this dissertation, we consider an alternative dispatching method that necessitates careful design of an underlying network. In this scheme, a truckload on its …

A Hybrid Kinematic-Acoustic System For Automated Activity Detection Of Construction Equipment, Yong-Cheol Lee

Faculty Publications

Automatically recognizing and tracking construction equipment activities is the first step towards performance monitoring of a job site. Recognizing equipment activities helps construction managers to detect the equipment downtime/idle time in a real-time framework, estimate the productivity rate of each equipment based on its progress, and efficiently evaluate the cycle time of each activity. Thus, it leads to project cost reduction and time schedule improvement. Previous studies on this topic have been based on single sources of data (e.g., kinematic, audio, video signals) for automated activity-detection purposes. However, relying on only one source of data is not appropriate, as the …

Heat Wave Intensity Duration Frequency Curve: A Multivariate Approach For Hazard And Attribution Analysis, Omid Mazdiyasni, Mojtaba Sadegh, Felicia Chiang, Amir Aghakouchak

Civil Engineering Faculty Publications and Presentations

Atmospheric warming is projected to intensify heat wave events, as quantified by multiple descriptors, including intensity, duration, and frequency. While most studies investigate one feature at a time, heat wave characteristics are often interdependent and ignoring the relationships between them can lead to substantial biases in frequency (hazard) analyses. We propose a multivariate approach to construct heat wave intensity, duration, frequency (HIDF) curves, which enables the concurrent analysis of all heat wave properties. Here we show how HIDF curves can be used in various locations to quantitatively describe the likelihood of heat waves with different intensities and durations. We then …

Quantification Of Mitochondrial Membrane Potential In The Isloated Rat Lung Using R6g, Anthony Cammarata

Master's Theses (2009 -)

Mitochondrial membrane potential (Δm) plays a key role in vital mitochondrial functions, and its dissipation is a hallmark of mitochondrial dysfunction in various cell types. The objective of this study was to develop an experimental and computational approach for estimating Δm in intact rat lungs using the lipophilic fluorescent cationic dye rhodamine 6G (R6G). Rat lungs were isolated and connected to a ventilation-perfusion system. The experimental Protocol consisted of three single-pass phases: loading, wash, and uncoupling, in which the lungs were perfused with R6G-containing perfusate, fresh R6G-free perfusate, or R6G-free perfusate containing the mitochondrial uncoupler FCCP, respectively. This Protocol was …

Biomethane Production From Biodegradable Plastics, Nicholas John Norio Benn

Master's Theses (2009 -)

Organic polymer plastics are often short-lived commodities for single-use that result in landfill buildup and persistence in the environment. Plastic waste accumulation can cause ecological damage. Plastic production continues to outpace plastic waste management and perpetuates the growing epidemic of plastic pollution. More efficient handling of plastics would be beneficial. One improvement involves biodegradable plastics (i.e., bioplastics), particularly polylactic acid (PLA) and polyhydroxyalkanoates (PHA), which can alleviate environmental concerns stemming from mismanagement. Yet, there are currently no bioplastic waste management strategies scalable to handle the millions of pounds of bioplastics that enter the waste stream. Therefore, new bioplastic resource recovery …

Chemical Pretreatment And Dewaterability Of Aanaerobically Digested Bio-P Biosolids, Eileen Margaret Kennedy

Master's Theses (2009 -)

Phosphorous (P) effluent regulations from water resource recovery facilities (WRRFs) have become more stringent to reduce the damage of eutrophication caused by excess amounts of P. Enhanced biological phosphorus removal (EBPR) is a popular method to help comply with these regulations combined with other practices such as filtration. However, the sludges from facilities that employ EBPR (bio-P sludges) are difficult to dewater and require more polymer than conventional sludge, thereby increasing the cost of solids handling at these facilities. The monovalent to divalent (M/D) cation ratio, which is important in dewatering, is reportedly altered during the EBPR process. P speciation …

Synthesis And Secretome Release By Human Bone Marrow Mesenchymal Stem Cell Spheroids Within Three-Dimensional Collagen Hydrogels: Integrating Experiments And Modelling, Jyotsna Joshi, Mohammadreza Dehghan Abnavi, Chandrasekhar R. Kothapalli

Chemical & Biomedical Engineering Faculty Publications

Myocardial infarction results in loss of cardiac cell types, inflammation, extracellular matrix (ECM) degradation, and fibrotic scar. Transplantation of bone marrow-derived mesenchymal stem cells (BM-MSCs) is being explored as they could differentiate into cardiomyocyte-like cells, integrate into host tissue, and enhance resident cell activity. The ability of these cells to restore lost ECM, remodel the inflammatory scar tissue, and repair the injured myocardium remains unexplored. We here elucidated the synthesis and deposition of ECM (e.g., elastin, sulfated glycosaminoglycans, hyaluronan, collagen type III, laminin, fibrillin, lysyl oxidase, and nitric oxide synthases), matrix metalloproteinases (MMPs) and their inhibitors (TIMPs), and other secretome …

Differential Cortical Activation During The Perception Of Moving Objects Along Different Trajectories, Finnegan J. Calabro, Scott A. Beardsley, Lucia M. Vaina

Biomedical Engineering Faculty Research and Publications

Detection of 3D object-motion trajectories depends on the integration of two distinct visual cues: translational displacement and looming. Electrophysiological studies have identified distinct neuronal populations, whose activity depends on the precise motion cues present in the stimulus. This distinction, however, has been less clear in humans, and it is confounded by differences in the behavioral task being performed. We analyzed whole-brain fMRI, while subjects performed a common time-to-arrival task for objects moving along three trajectories: moving directly towards the observer (collision course), with trajectories parallel to the line of sight (passage course), and with trajectories perpendicular to the line of …

Development Of An Autonomous Aerial Toolset For Agricultural Applications, Terrance Life

Mahurin Honors College Capstone Experience/Thesis Projects

According to the United Nations, the world population is expected to grow from its current 7 billion to 9.7 billion by the year 2050. During this time, global food demand is also expected to increase by between 59% and 98% due to the population increase, accompanied by an increasing demand for protein due to a rising standard of living throughout developing countries. [1] Meeting this increase in required food production using present agricultural practices would necessitate a similar increase in farmland; a resource which does not exist in abundance. Therefore, in order to meet growing food demands, new methods will …

Impact Of Titanium Dioxide Nanoparticles On Nutrient And Contaminant Reduction In Wastewater Treatment Wetlands, Madeline Hubbard

Civil and Environmental Engineering Master's Project Reports

Metallic nanoparticles are found in a variety of commercial products and industrial processes, and have become more common in the last few decades. As nanoparticles are toxic to biota and have the potential to spread other types of contamination, their increased use has become a concern. Research into the transport of nanoparticles in subsurface and surface waters shows a wide range in mobility, but that they are most likely to collect in systems with low linear velocities and high organic content. As a result, wetlands are the most vulnerable to nanoparticle contamination. Wetlands receiving and treating wastewater effluent have an …
