How Unstructured Data From The Data Warehouse Can Be Used With Machine Learning And Visualization To Develop Novel Medical Technologies, Alfred A. Cecchetti

Faculty Research Day

Machine Learning (ML) can accurately classify and accurately predict disease as well as other medical events.

Device Programming, especially smartphone applications, can provide new ways to acquire, transport, store, process, and secure personalized patient data to deliver meaningful results.

Sensing And Quantifying A New Mechanism For Vehicle Brake Creep Groan, Dejian Meng, Lijun Zhang, Xiaotian Xu, Yousef Sardahi, Gang Chen

All Engineering Faculty Research

This paper investigates the creep groan of a vehicle’s brake experimentally, analytically, and numerically. Experimentally, the effects of acceleration on caliper and strut, noise, brake pressure, and tension are measured. The results show that the measured signals and their relevant spectra broadly capture the complex vibrations of creep groan. This includes the simple stick-slip, severe stick-slip vibrations/resonances, multiple harmonics, half-order harmonics; stick-slip-induced impulsive vibrations, steady/unstable vibrations, and their transitions. Analytically, a new mathematical model is presented to capture the unique features of half-order harmonics and the connections to fundamental stick-slip/resonant frequency and multiple harmonics. The analytical solution and the experimental …

Assessment Of Live Load Distribution Characteristics Of Press-Brake-Formed Tub Girder Superstructures, Guilherme Petty

Theses, Dissertations and Capstones

The scope of this thesis project was to refine the development of live load distribution factors for tub girders. This was done in three stages. First, experimental data was gathered to assess live load distribution on the Amish Sawmill Bridge located in Fairbank, Iowa. Then, finite element analysis models were developed to benchmark against experimental data. Finally, a series of parametric studies were performed to explore the distribution factors of steel tub girders under various design conditions and to generate more accurate live load distribution factors. Results drawn from this research project demonstrate that press-brake-formed steel tub girders exhibit consistent …

Smart Roads: Investigating Roadways As Energy Sources For Potential Application Of In-Lane Charging, Dhruvalkumar Hitendrakumar Patel

Theses, Dissertations and Capstones

The main aim of this thesis is to explore the potential for using pavements as part of energy harvesting infrastructure. Asphalt pavements can be used for multiple purposes such as for energy harvesting, eco-friendly use of the car, and the utilization of the natural renewable resources to produce electricity and that electricity use for in-lane charging technology which helps to charge a car when it is being driven on the road. The wireless charger is set-up under the asphalt pavement, and it will produce the magnetic field. The piezoelectric material and wind turbine are the electric source for applications such …

Numerical Simulation For The Hydrodynamic Performance Of Hydropower Turbine Near Free Surface, Zeda Yin

Theses, Dissertations and Capstones

The performance of hydropower turbine in shallow water can be affected by the presence of free surface. Therefore, it is of great interest to investigate the influence of free surface on hydropower turbine performance through computational simulations. For a better understanding of flow field around hydropower turbine operating in shallow water, it is important to analyze the flow over a single hydrofoil beneath free surface first. Therefore, as the first part of this thesis, the Computational Fluid Dynamics (CFD) methodology was used for numerical simulation of 2D unsteady incompressible viscous flow over a hydrofoil under the free surface. The computation …

Developments Towards High-Flux Silica Nanosphere Substrates To Support Conforming Self-Assembled Gold Nanoparticle Monolayers For Applications In Size-Selective Filtration, Ryan Baker Vincent

Theses, Dissertations and Capstones

Hydrophobic thiol coated gold nanoparticles have recently been investigated for their ability to self-assemble into robust, ultra-thin, porous membranes at a liquid-vapor interface. Due to the well-ordered, hexagonal close-packed nanoparticle arrays formed during the self-assembly process, these 2-dimensional sheets have very well-defined pore structures and have been shown to span gaps of several microns under ideal conditions. While these self-assembled nanoparticle monolayers have very promising applications in the field of size-selective filtration due to their well-defined pore structure, they need to be supported by a rigid substrate with a large amount of open area. Here, tightly packed arrays of silica …
