The Etherification of HMF: One Step to Create Renewable Tunable Polymers from HMF There is a desire to use biomass to replace oil as the feedstock for modern chemicals and products. In this study, we seek to create tunable polymers using 5-hydroxymethylfurfural (HMF) as a renewable platform chemical. The properties of the final polymer can be tuned by modifying the side-chain of the monomer, which is added by the etherification of HMF. Several different catalysts with a variety of active sites and pore structures were evaluated for their activity in the etherification reaction. We have also evaluated the interplay of R-group identity and active site structure on the etherification kinetics. Catalysts possessing... Read More →

Photocatalysis of Atrazine by various Bismuth Oxyhalides: Rates, Mechanisms and Byproducts (Section F Poster 22, 1:00PM-2:15PM) | | Atrazine has been found to be one of the most prevalent pollutant in worldwide water systems. Typically a result of herbicide runoff, the harmful environmental impacts of the compound cause novel methods of treatment to gain interest, such as photocatalysis. Photocatalysis involves the addition of a catalyst and light source for enhanced degradation of pollutants, and offers an efficient method for atrazine treatment in water. Bismuth oxyhalides (BiOX) have previously been investigated by the Patterson Research Group as catalysts for the degradation of atrazine, as results have shown comparable degradation rates to EPA photocatalytic standards. BiOX compounds will be doped with various nonmetals in attempt to enhance photocatalytic activity. The goal of this project is to assess various BiOX based... Read More →

Event Viewer – A platform for the exploration and visualization of events | | The need for exploratory spatial and temporal data analysis tools has increased with the growth of sensor systems that produce large data sets combining spatial, temporal, and thematic attributes. While geographic information system (GIS) software supports exploration of spatial data, and time series analysis tools, such as MATLAB, support exploration of temporal data, these tools do not intuitively present the spatial and temporal relationships between events. The developed prototype implements a framework for visualizing and exploring spatial, temporal and thematic sensor-based data. The prototype system is an initial realization of a conceptual model, the Event Viewer, designed by Kate Beard, Heather Deese, and Neal R.

Analyzing the Scalability of Embedded Ice Sheet Modeling | | Understanding the impact of global climate change is a critical concern for society at large. One important piece of the climate puzzle is how large-scale ice sheets, such as those covering Greenland and Antarctica, respond to a warming climate. Given such ice sheets are under constant change, developing models that can accurately capture their dynamics represents a significant challenge to researchers. An emerging modeling paradigm to capture the dynamics of an ice sheet model is through model embedding, where a high-resolution ice sheet model is embedded within a large-scale low-resolution ice sheet model. Such a method has computer performance implications that are not yet fully understood, particularly because computational resources are divided among the models. | This poster presents a study into the scalability of model embedding with large-scale state-of-the-art supercomputers. Our overall goal is to prove that the embedded model can scale well with large numbers of processors, compared to non-embedded ice sheet modeling. For our tests, we utilize the Stampede supercomputer, housed at the Texas Advanced Computing Center. Using Stampede we have simulated both embedded and non-embedded models at varying core counts. The embedded model has also been simulated at varying processor distributions, where the high resolution model is given a larger or smaller share of the processors. Our initial findings show that the embedded model enjoys a decrease in run-time with increasing processor counts. We have also shown that twenty-five percent of processors devoted to the high-resolution embedded model provides the best overall performance. | | Faculty Mentor: Phillip... Read More →

Production and characterization of continuous filaments from cellulose nanofibrils (CNF), a novel application of wood based materials | | A novel method for the production of filaments from cellulose nanofibers is proposed in order to find a new application for wood based materials. Properties of filaments produced from three different nanocellulose suspensions are studied. These were obtained by grinding the original CNF in different grinding times of 50 minutes, 100 minutes and. A new setting of syringe spinning is introduced for nanocellulose filament production and the resulted filaments were air dried. Morphology of the samples were studied using scanning electron microscopy (SEM) micrographs and atomic force microscopy (AFM) imaging. Surface properties of samples were studied using surface analysis and attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR). Influence of grinding time on mechanical properties of the CNF filaments were further investigated through tensile tests. Statistical testing was used for the comparison of the results and it was observed that grinding CNF has a significant influence on the tensile properties of the filaments. | | Faculty Mentor: Mehdi...

sFROST: a Spiking Model of Working Memory Maintenance | | Neurocomputational modeling is a powerful tool for grounding explanations of cognitive processes within neuroanatomical and neurophysiological constraints. The FROST (FROntal-Striatal-Thalamic) model of working memory maintenance proposes that to-be- remembered items are encoded in the lateral prefrontal cortex and maintenance depends upon reverberant activity in a network of cortical and subcortical structures (i.e., basal ganglia, thalamus). The original version of FROST predicted continuous membrane potentials. In the present work, we develop a spiking version of FROST (sFROST) that offers an increase in neurobiological realism. Benchmark simulations demonstrate that sFROST successfully accounts for single-cell recording data and human behavioral data. The impact of scaling the model (i.e., increasing number and connectivity of neurons) and adding a more detailed basal ganglia network will be investigated. | | Faculty Mentor: Shawn... Read More →

Creating a Seamless Robot Design for the Application of Synthetic Liquid-Repellent Surfaces in Soft Robots | | Recently, soft robots have created significant interest in the scientific community due to their applications in industry, agriculture, the medical field, and more. However, the majority of these applications expose the soft robot to harmful fouling agents such as blood, dirt, or oil. To overcome this problem, SLIPS Technologies, a materials company in Massachusetts, has created a slippery surface that uses the recently discovered concept of immobilized liquid layers to repel both simple and complex foulants. One of the challenges that SLIPS Technologies is currently facing is that their... Read More →

Mooring Load Analysis on Oyster Farm in Estuary | | The goal of this project is to observe different environmental loading that affect the performance of the long-line rope and mooring system of an oyster farm. A proper design of the mooring lines and anchoring system requires an evaluation of the forces that affect the system, which are divided into quasi-static and dynamic loads. The quasi-static loads mainly include weight and buoyancy, while the dynamic loads include wind, current and wave forces. Tidal variations primarily induce changes in static tension of the lines, which in turn manifest as changes in buoyancy forces on the cage system. The variation in static tension on the mooring lines is typically re-mediated by elastic stretching of the mooring lines, but in severe cases a change in the mooring line configuration may be required. Progressive deterioration can occur in the mooring line material due to this process of repeated loading. Catastrophic damage is also likely to occur if the maximum tension exceeds the breaking strength of a line. To avoid this situation, mooring designers of offshore structures usually adopt a safety factor of 1.6... Read More →

Storm surge mitigation through kelp-type canopy | | Most of the coastline of the United States are vulnerable to the threat of the hurricanes. Associated with hurricanes, storm surge is the main risk to coastal communities. Mitigating storm surge has become a hot topic in coastal engineering. In this study, a 1D model was developed to analyze storm surge attenuation through an idealized kelp farm. The analytical solution provided promising results, indicating that kelp farms can reduce storm surge energy flux and set-up. There are two main factors that impact the storm surge energy flux reduction and set-up reduction, i.e., the ratio of the kelp farm induced drag to wind/bottom stress and the ratio of the hydrostatic pressure to wind/bottom stress. Generally, the kelp farm with larger size or density under larger wind speed and higher incident total water column height will enhance the capability of the kelp farm on storm surge attenuation. | | Faculty Mentor: Kimberly...

Integrated Environment & Proximity Sensing for UAV Applications | | As the realm of drone applications expand new methods for sensing, navigating and avoiding obstacles need to be developed. The project applies an Extended Kalman Filter to a simulated quadcopter vehicle though Matlab in order to estimate not only the vehicle state but the world state around the vehicle. The EKF takes in multiple sensor readings from range sensors, IMU sensors, and radiation sensors and combines this information to optimize state estimates. The result is an estimated world map to be used in vehicle navigation and obstacle avoidance. | The simulation handles the physics behind the vehicle flight. We know as a result of the motors there will be two primary forces acting on the vehicle, thrust and drag. These forces provide linear and rotational accelerations. These values can be integrated to determine vehicle flight path. This process determines the actual values of the vehicle state. Coupled into the integration process is the ability to tweak how fast the motors spin. Using this, A controller is built in to the vehicle such that desired vehicle states (position, velocity, and orientation) can be achieved. Additionally, sensing methods are simulated following known detection procedures and statistics to provide as accurate sensing models as possible. | The Extended Kalman Filter is used here due to some non-linear components of the estimation model. The estimation model includes the states for the vehicle, nearby world objects, nearby radiation measurements. By combining IMU and GPS data with additional measurement data for an EKF, an estimation method attempts to combine all three... Read More →
