Characterization Of Magnetic Thin Films Using The Magneto Optic Kerr Effect, Nicholas J. Savino

Student Scholar Showcase

Understanding magnetic properties of materials allows for advances in applications such as data storage. The Magneto-Optic Kerr Effect (MOKE) displays the reflective response a magnetic material has to a magnetic field. When polarized light reflects off of a magnetic material, the polarization orientation can change. The application of an external magnetic field can affect how much this polarization changes in a non-linear manner. Hysteresis loops are created when examining the relationship between intensity of the reflected light to the applied magnetic field provide information about magnetic properties of that material, such as the coercive field and field retention. Preliminary measurements …

A Longitudinal Analysis On The Cyclical Pattern Of The Us Airline Industry, Michelle Bennett

Discovery Day - Prescott

The Airline Quality Rating (AQR) is the nation’s most comprehensive study of airline performance and quality for over two decades. The AQR sets the industry standard, providing consumers and industry watchers a way to compare performance quality among different US airlines using objective performance-based data (Bowen and Headley, 2014). The quantitative weighted average is computed monthly for every airline and divided by the sum of the weight to create the index. Criteria weighted in this formula include baggage handling, customer complaints, denied boarding and on time arrivals. This research employs the application of a longitudinal analysis methodology resulting in finding …

Can The Presence Of A 1/F Structure In Stride-To-Stride Variability Enable Us To Withstand Falls?, Jenny A. Kent, Andreas Skiadopoulos, Jordan Wickstrom, Nikolaos Stergiou

UNO Student Research and Creative Activity Fair

Falls are a persistent threat to longevity and quality of life, affecting 1/3 of older adults living in the community each year. There is strong evidence suggesting that a particular pattern within our walking reflects an ability to adapt to a continually changing environment. Specifically, the stride-to-stride patterns of healthy walking have a 1/f frequency spectrum. This has been observed to degrade to varying extents with aging and pathology. The aim of this study was to determine whether the presence of this structure of variability is related to an increased ability to withstand perturbations. We hypothesized that individuals who demonstrated …

Fracture Toughness Of Cast And Extruded Al6061/15%Al2o3p Metal Matrix Composites, Alan K. Hellier, A. G. Crosky, H. A. Hassan, J. J. Lewandowski

Faculty of Engineering and Information Sciences - Papers: Part A

Particulate reinforced metal matrix composites (PRMMCs) are of interest owing to the low cost of their raw materials and their ease of fabrication, making them suitable for applications requiring relatively high-volume production. The improved properties of PRMMCs result from the addition of hard ceramic particles (such as Al2O3 or SiC); the size, shape, volume fraction, interfacial properties and distribution of these (together with the fabrication method) determine the mechanical behaviour of the composite. However, PRMMCs have inferior ductility, toughness and low-cycle fatigue properties compared with unreinforced alloys, often limiting their usefulness in practice. Reinforcements of between 15 volume % and …

Residual Stress Effects On Fatigue Crack Growth From A T-Butt Weld Toe, Alan K. Hellier, H. Li, B. G. Prusty, G. M. Pearce, M. Reid, A. M. Paradowska

Faculty of Engineering and Information Sciences - Papers: Part A

A350 grade black mild steel is one of the most widely used structural materials in the world, being commonly found in buildings, bridges and offshore structures.Welding is commonly used to join two plates of structural steel and this often takes the form of a T-butt.In addition, other more complex geometrical joints are often simplified for stress analysis purposes by approximating them as 2-D T-butt plate models (e.g. skewed T-joints, cruciform welded joints, tubular welded joints, pipe–plate joints, etc.).However, all such welds are potentially susceptible to fatigue crack initiation and slow but accelerating growth arising as a result of fluctuating service …

Electrochemical And Spectroscopic Study Of Peptide-Template Melanins, Daniel Courter, Olivia Rossi, Zhen Tian

Honors Theses and Capstones

Melanins are organic polymers made up of 5,6-dihydroxyindole carboxylic acid (DHICA) and 5,6-dihydroxyindole (DHI). Biochemical systems synthesize melanins through a complex reaction pathway. Previous research exhibited that naturally-occurring melanins (NatMel) and their synthetic analogues (SynMel) can potentially serve as electrode materials for aqueous charge storage devices. Small surface area creates technical challenges for these melanins as charge storage materials. This research herein demonstrates that the structure of melanins can affect the charge storage capacities of monovalent Na⁺cations and divalent Mg²⁺ cations. 2-D sheet-like peptide melanins (PepMel) were synthesized into tripeptides consisting of aspartic acid (D), phenylalanine (F), …

Semiconductor Technology for Ultra-Large Scale Integrated Circuits and Thin Film Transistors VI (ULSIC vs TFT 6)

Artificial intelligences are promising as key technologies in future societies. However, the conventional ones are executed using complicated software on high-specked hardware, and the machine size is very bulky and power consumption is unbelievably huge. Therefore, we are investigating "braintype integrated system", namely, neural network built only by hardware, which can be compact, low power, robust, and integrated on everything in future. In order to realize that system, simplification of the processing elements, such as neurons and synapse, three-dimensional structure, and low cost fabrication are required. We have succeeded in that simplification and are trying to utilize oxide semiconductors for …

Monitoring Of Applied Stress In Concrete Using Ultrasonic Full-Waveform Comparison Techniques, Ali Hafiz

Student Research Symposium

Ultrasonic testing is a non-destructive approach commonly used to evaluate concrete structures. A challenge with concrete is that it is heterogeneous, which causes multiple wave scattering resulting in longer and more complex wave paths. The recorded ultrasonic waveform can be divided into two portions: the coherent (or early) and the diffuse (or Coda) portion. While conventional methods only use the coherent portion, e.g. the first wave arrival to determine the wave velocity, we are interested in the entire waveform, i.e. until the wave amplitude is completely dampened out. The objective of this study was to determine what portion of the …

Validation Of Postural Sway Measurements Using Wii Balance Board, Zachary Meade

UNO Student Research and Creative Activity Fair

Standing balance measurements, such as postural sway, are vital for determining functional ability, risk of falling and recovery of injuries. Often the need to collect data outside of the typical clinical or research setting arises. However, obtaining these measurements outside of a laboratory setting can be very difficult, as the mobility of a laboratory-grade force plate (FP) is minimal, and its cost can be upwards of $20,000. The purpose of this study is to create a cheaper alternative by validating the Wii Balance Board’s (WBB; Nintendo, Redmond, Washington, USA) ability to measure postural sway patterns. The WBB can be acquired …

On Utilizing Big Data To Assess Health Levels, Elham Rastegari

UNO Student Research and Creative Activity Fair

The general relationship between mobility/gait patterns and health conditions, has been established by many research studies. Gait patterns have been used in predicting fall incidents, assessing the movement of people with Parkinson disease and assessing gait characteristics of patients with major depression. However, not much has been reported in terms of how to utilize mobility data along with gait patterns to assess health levels and to identify early stages of certain diseases or conditions that impact mobility/gait patterns. In this project, we propose to develop a population analysis system based on recent Big Data technologies that relies on different types …

Autonomous Uav Navigation In An Indoor Environment For Warehouse Inventory Recording, Venkat Ramana Reddy Garlapati

UNO Student Research and Creative Activity Fair

UAV’s are currently used extensively in outdoor environments for various applications, including wildfire monitoring, and agricultural surveying, their use in indoor applications have been fairly restricted, owing mainly to the difficulty to maneuver them in smaller indoor spaces and the inability to use GPS-based navigation system. Nevertheless, there are many indoor applications where UAVs could provide a safe, reliable and resilient means to perform operations that are dangerous for humans such as surveillance inside chemical plants, inventory scanning in cold storages etc., Autonomous UAV navigation in an indoor environment can be achieved by finding a collision-free flight path to pass …

A Hierarchical Learning Model For Extracting Public Health Data From Social Media, Elham Rastegari

Fracture Toughness Measurement For Aluminium 6061-T6 Using Notched Round Bars, Alan K. Hellier, P. P. Chaphalkar, B. G. Prusty

Faculty of Engineering and Information Sciences - Papers: Part A

Current standard testing methods for determining plane strain fracture toughness (KIc), such as ASTM E399 and ASTM E1820, require a prior estimate of KIc, plus the specimens are large, involve a lot of machining and need fatigue pre-cracking. There is therefore a desire to develop new testing techniques which are simple, as well as cost and time effective. While the use of tensile notched round bars (NRB) test pieces is not novel, dating back to a conference paper by Brown in 1975, relatively few authors have so far attempted this.
