The use of these device models demonstrate a successful first-pass design, putting less dependence on classical load …
Investigating Virtual Globes For A Prototype Community Archive Of 3d Subsurface Data, Derek C. Whitman
Investigating Virtual Globes For A Prototype Community Archive Of 3d Subsurface Data, Derek C. Whitman
Theses and Dissertations
Geoscience data sharing and processing is very advanced in terms of surface data. Subsurface data sharing has not received the attention that surface data sharing has received and so there are fewer applications or software packages which focus on it. This research is funded by the NSF EarthCube GEO Domain program in an effort to develop a continental-scale repository of 3D subsurface data to facilitate the sharing of complex 3D data and to enable the development of geoprocessing tools and workflows that operate on that data. The work in this thesis is a small part of the EarthCube project with …

Molecular And Device Engineering Towards The Study Of Potential Anti-Mrsa Agents, Powell Fansler, Karla Geisse, Ryan Marshall
Bioengineering Senior Theses
At the intersection of bio-device engineering and bio-pharmaceutical studies, our project involved the design of a hydraulic manifold to be used in isothermal titration calorimetry (ITC), with the ultimate goal of using ITC to study the thermodynamic binding parameters of potential anti-Methicillin Resistant Staphylococcus aureus (MRSA) agents to our drug target, Sortase A. The hydraulic manifold redesign included the analysis of materials such as high density polyethylene (HDPE), polytetrafluorethylene (PTFE, ‘Teflon’), and polycarbonate as well as the implementation of a new construct of the manifold itself. Sortase A is a transpeptidase found in Gram-positive bacteria and catalyses the attachment of …

Mechanical Engineering Presentations And Conference Materials
This work presents the development of a multi-input, multi-output neural network structure to predict the time dependent concentration of chemical agents as they participate in chemical reaction with environmental substrates or moisture content within these substrates. The neural network prediction is based on a computationally or experimentally produced database that includes the concentration of all chemicals presents (reactants and products) as a function of the chemical agent droplet size, wind speed, temperature, and turbulence. The utilization of this prediction structure is made userfriendly via an easy-to-use graphical user interface. Furthermore, upon the knowledge of the time-varying environmental parameters (wind speed …
Broadband, Non-Destructive Characterisation Of Pec-Backed Materials Using A Dual-Ridged-Waveguide Probe, Milo W. Hyde Iv, Michael J. Havrilla
Broadband, Non-Destructive Characterisation Of Pec-Backed Materials Using A Dual-Ridged-Waveguide Probe, Milo W. Hyde Iv, Michael J. Havrilla
Faculty Publications
A new probe which utilises a dual-ridged waveguide to provide broadband, non-destructive (ND) material characterisation measurements of a perfect electric conductor (PEC)-backed material is introduced. The new probe possesses a bandwidth similar to existing coaxial probes and is structurally robust like rectangular waveguide probes. The combinations of these two qualities make it especially attractive for ND inspection/evaluation applications in the field. The theoretical development of the dual-ridged-waveguide probe is discussed. A magnetic field integral equation is derived by applying Love’s equivalence theorem and enforcing the continuity of transverse fields at the dual-ridged-waveguide aperture. The magnetic field integral equation is then …

Tail: Data Structures Tutorial Site, Lauren Jauco, Ian Parker, Allie Rodriguez, Tyler Upadhyaya
Computer Science and Engineering Senior Theses
Any intermediate computer programmer will learn data structures. A data structure stores and organizes in-formation into useful groups in order for a computer program to run as efficiently as possible. Data structures become extremely important when managing large amounts of data, whether it be as simple as managing statistics for a basketball team, or as critical as accounts for online banking. The current way to learn data structures is through classes and online Java applets. In classes, most professors teach by drawing the data structure and editing the information on a board. Data structure tutorial websites mimic this visual way …
