Growth Kinetics Of Carbon Microcoils
Growth Kinetics Of Carbon Microcoils
Stander Symposium Projects
Carbon is one of the most versatile materials of the periodic table and exists in various allotropic forms and shapes including fullerene, carbon nanotube, graphene. Coiled carbon filaments exhibit very attractive morphology and properties such as absorption of electromagnetic waves and high conductivity because of their shape and carbon structure. Bidirectionally grown double helical carbon microcoils (CMCs) are one type of coiled carbon filaments with unique catalytic activity. In this study, CMCs were synthesized using a chemical vapor deposition method. Growth mechanism of CMCs was explained by a simple exponential catalyst decay model.
Human Re-Identification In Multi-Camera Systems
Human Re-Identification In Multi-Camera Systems
Stander Symposium Projects
This research involves live human re-identification on multi-camera systems. Each frame of multiple cameras needs to be captured and analyzed with image processing methods. First, a histogram of oriented gradients (HOG) is performed to identify a person in each frame. Next, Local Binary Pattern (LBP) descriptors are used on each person to determine certain set features about then. Lastly, a red, green, blue (RGB) color histogram is performed on a specific body mask. Each body is then given a label based on their LBP and color histogram information and that label will be sent to a database. This label should …

Stander Symposium Projects
A LiDAR point cloud is 3D data which contains millions of data points represented in the form I (x, y, z) that stores the spatial coordinates and possibly RGB color information. This method of data collection is especially useful in collecting large scale scene information. The goal of this project is to develop a self-adaptive and automated methodology to extract features which effectively represent object regions, specifically man-made objects and vegetation regions. The point cloud will be initially segmented using a strip histogram grid approach. Once significant features are extracted, region refinement by surface growing will be performed. Finally after …
Job Design: A Human Approach Through Catholic Social Teaching And Job Design Theories
Job Design: A Human Approach Through Catholic Social Teaching And Job Design Theories
Stander Symposium Projects
Job design theories outline jobs that help a company design jobs that are efficient and productive for a laborer to do. Catholic Social Teaching enlightens humanity that above all it is important to respect human dignity. Do Catholic Social Teaching and job design theories agree or are they at odds with each other? “Job Design: A Human Approach” looks at the story of each starting with Fredrick Taylor in 1911 and Pope Leo XIII in 1891 and identifies similarities and differences. Finally, the thesis uses the stories of each to look forward into the modern world of the jobs yet …
Preparing Pre-Service Teachers To Work With English Language Learners
Preparing Pre-Service Teachers To Work With English Language Learners
Stander Symposium Projects
English Language Learners (ELLs) can be misidentified as students with special needs. Teachers often watch these students struggle in school and assume they have a cognitive delay, when in reality; they may just be struggling with their language delay. To be identified as needing special education services, these students undergo assessments to test their abilities. These assessments were created for students who speak English. Studies have shown that “Familiarity with Standard English accounts for more than 50% of the total test variance on IQ and achievement test measures for fourth graders and 60% to 90% of the variance for seventh …

The Impact Of Social Awareness, Empathy, And Confidence On Blindness To Change In Facial Emotions
The Impact Of Social Awareness, Empathy, And Confidence On Blindness To Change In Facial Emotions
Stander Symposium Projects
Change blindness (CB) is an inability to detect changes in a visual stimulus. For example, Simons & Chabris (1999) used videotaped scenes depicting a gorilla walking across the screen, typically unnoticed by observers. The present research investigated blindness to changes in facial indications of emotion. Previous studies have shown that gradual changes of facial emotion produce substantive levels of CB when assessed by verbal report (David et al., 2006). It has also been noted that observers express high levels of confidence in their ability and accuracy to detect a change in a stimulus if it were to take place, even …
Research Exercise: The "Genocide" Of Timor-Leste: A Study Of Human Suffering And International Ignorance
Stander Symposium Projects
The Indonesian occupation of Timor-Leste in 1975 resulted in the deaths of an estimated 200,000 Timorese, which accounted for more than a quarter of the territory’s total population. Unfortunately, this terrible injustice went almost completely unrecognized by the international community. Even more disturbing, there is evidence to suggest that the United States was not only aware of these injustices, but perhaps encouraged the Indonesians’ violent invasion. A mass killing of this magnitude is normally dubbed ”genocide.” However, the situation that occurred in Timor-Leste has never been labeled as an actual “genocide,” most likely due to the involvement of the United …

We're Here To Help: Accessing The Needs Of Transfer Students.
We're Here To Help: Accessing The Needs Of Transfer Students.
Stander Symposium Projects
The need to assist transfer students is particularly important because transfer students enter into new institutions with unique needs, perspectives, and experiences compared to non-transfer students. Many orientation programs do not address the needs of transfer students and focus on freshman students. Little is known about the correlation between transfer students and orientation attendance. Therefore, this study aimed to identify transfer student needs, increase their attendance of orientation programs, and to provide effective programming for them. Participants were asked questions regarding barriers to program attendance and institutional support. This qualitative study focused on eight undergraduate students at a private, midsized, …
An Empirical Study Of The Relationship Between Stock Market Price Movements And Macro Financial Conditions, 2001-2013
Stander Symposium Projects
Since the early 90's, a number of financial condition indexes have been developed to determine future movementsin the non-financial sectors of the economy. In this study, I use the Kansas City Federal Reserve's index of financial Stress (KCFSI) to study the relationship between market and sector price movements and macro financial conditions. The periods of analysis are :(1)2001-2012), (2) 2003-2007,(3) 2009-2012). The long run period includes two recessions and two sustained periods of economic growth. The two short run periods represent economic rebound periods after the recessions. Using uni-variate regression models regress KCFSI on Spy, the S&P 500 ETF, as …
Assessing Aesthetic Preferences For Faces With Measures Of Ocular Gaze
Assessing Aesthetic Preferences For Faces With Measures Of Ocular Gaze
Stander Symposium Projects
Though one may assume that the reactions to two nearly identical works of art would be similar, the medium in which art is presented can influence an individual’s perception of the work (Locher et al., 2006). The present study evaluates aesthetic preferences for faces, specifically, relating to those influenced by art; this is done by comparing reactions when viewing classic portraits and photographic renderings of those portraits. Simultaneously portraits and photographs of faces, matched for variables such as gender, artistic medium, ethnicity, face shape, facial hair, hair color, eye color, and facial position (full or profile), are shown to participants …
Behavioral Activation In A Homeless Shelter: An Example Of Engaged Scholarship
Behavioral Activation In A Homeless Shelter: An Example Of Engaged Scholarship
Stander Symposium Projects
A Behavioral Activation Program is implemented and evaluated at a homeless shelter. Behavioral Activation, which is based on operant conditioning, refers to “...a therapeutic process that emphasizes structured attempts at engendering increases in overt behaviors that are likely to bring [the person] into contact with reinforcing environmental contingencies and produce corresponding improvements in thoughts, mood, and overall quality of life” (Hopko et al., 2003, p. 700). Guided by the Psycho-Ecological Systems Model (Reeb & Folger, 2013), this interdisciplinary research project utilizes the participatory community action research strategy (Reeb, 2006), the pedagogical technique of service-learning (Reeb, 2010), and multidimensional assessment. Hypotheses …

Research Exercise: Retrospective Analysis Of A 5-Week Summer Sports Program Indicates Health Improvements In 9-16 Year Olds
Stander Symposium Projects
(N=271). All measures were made at registration (pre) and at camp’s end (post) by trained NYSP staff. Data presented as mean ± s.d. and compared pre and post with paired t-tests. BMI was significantly reduced (23.2 ± 0.4 kg/m2 vs 22.4 ± 0.3 kg/m2; p<0.05) due to increases in height (1.55 ± 0.007 m vs 1.57 ± 0.007 m; p<0.05) and a trend towards decreased body weight (56.1 ± 1.1 kg vs 55.8 ± 1.0 kg; p=0.07). Mean arterial pressure was also significantly reduced (81 ± 0.5 mmHg vs 76 ± 0.4 mmHg; p<0.05) due to lowered systolic blood pressure (107.9 ± 0.7 mmHg vs 103.1 ± 0.6 mmHg; p<0.05). This preliminary analysis supports beneficial health impacts of NYSP. Further studies with standardized and additional health-related measurements would allow for more comprehensive analysis and insight into the underlying mechanisms of improvement or lack thereof.

As roundabouts become increasingly popular in Ohio, this study assesses their performance as a safe and functional alternative to traditional intersections. Focusing on three roundabout locations in Dublin, Ohio, the study compares accident reports with traditional intersections in the area as well as with the traditional intersections that existed before the roundabouts were installed.
Research Exercise: S&P 500 Sector Weights: The Case For Inverse Relative Price Strength
Research Exercise: S&P 500 Sector Weights: The Case For Inverse Relative Price Strength
Stander Symposium Projects
In this study, I used a relative price strength model called the Inverse Relative Price Strength (IRPS) to develop a portfolio of 10 sector exchange-traded funds (ETFs) and then compared their performance to the overall market. I used the IRPS model as a proxy for the return risk optimizing process developed by Markowitz et, al. The hypothesis that I am testing is that sectors with lower relative prices compared to the market will have higher excess returns. The hypothesis is tested over the period 2008-2012. This particular period is highly volatile with large swings in both actual and relative prices. …
Low Alloy Steel Susceptibility To Stress Corrosion Cracking In Hydraulic Fracking Environment
Low Alloy Steel Susceptibility To Stress Corrosion Cracking In Hydraulic Fracking Environment
Stander Symposium Projects
The pipelines used for the process of hydraulic fracturing (aka. “fracking”) process are constantly operating at very high pressure and thus are highly susceptible to Stress Corrosion Cracking (SCC). This is primarily due to the process of carrying out fracking at a shale gas site, where the hydraulic fracking fluid is pumped through these pipes at very high pressure in order to initiate fracture in the shale formation. While the fracking fluid is typically more than 99% water, other components are used to perform various functions during the fracking process. Research into the occurrence of SCC reveals that SCC is …

Formulation To Predict Lower Limb Muscle Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, A. Barjau, Benjamin J. Fregly, Josep M. Font-Llagunes
Formulation To Predict Lower Limb Muscle Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, A. Barjau, Benjamin J. Fregly, Josep M. Font-Llagunes
Mechanical and Aerospace Engineering Faculty Publications
The human body has more muscles than Degrees of Freedom (DoF), and that leads to indeterminacy in the muscle force calculation. This study proposes the formulation of an optimization problem to estimate the lower-limb muscle forces during a gait cycle of a patient wearing an instrumented knee prosthesis. The originality of that formulation consists of simulating muscle excitations in a physiological way while muscle parameters are calibrated. Two approaches have been considered. In Approach A, measured contact forces are applied to the model and all inverse dynamics loads are matched in order to get a physiological calibration of muscle parameters. …

A Pilot Study Of The Effect Of An Acute Vestibular Therapy On Postural Stability And Gaze Patterns Of Children With Autism Spectrum Disorder
Stander Symposium Projects
Children with Autism Spectrum Disorder (ASD) struggle with sensory regulation, resulting in abnormal gaze patterns and decreased postural stability. Sensory integration (SI) therapy is a common therapy used to help children with ASD with these issues, however, there is insufficient quantitative research concerning its effectiveness. A pilot study is currently being conducted to quantify the acute effects of a SI vestibular treatment on postural stability and gaze patterns. Both children diagnosed with ASDs and typically developing children are participating in the study, and test methods include quiet standing posturography and analysis of socially relevant visual fixations recorded by a mobile …
Understanding Chinese Students In A Global Context
Understanding Chinese Students In A Global Context
Stander Symposium Projects
Nowadays, more and more Chinese students choose to study in American higher education institutions. According to "Open Doors," the number of Chinese students enrolled at American colleges jumped 23% between 2010 and 2011, to 194,029, which is 25% of the total number of international students enrolled at American colleges. Along with that increase various challenges arise. The need to address global-centered settings becomes more and more urgent in American higher education. American universities set up curriculum and co-curriculum based on the assumption that every student has some certain knowledge or skills, which are usually lacking in the case of international …

Gait modification represents a non-invasive method for reducing knee joint loading in patients with knee osteoarthritis. Previous studies have shown that a variety of gait modifications are effective in reducing the external knee adduction moment. The external knee adduction moment is often used as a surrogate measure of medial compartment force. However, a recent study showed that reductions in the external knee adduction moment do not guarantee reductions in medial compartment loads. Therefore, direct measurement of changes in knee contact force is important for determining the effectiveness of gait modifications. A previous study found that medial thrust gait and walking …

Mechanical and Aerospace Engineering Faculty Publications
In recent years, there has been a particular emphasis on identifying and delivering appropriate therapeutic interventions that address the significant balance and gait impairments that affect individuals with multiple sclerosis (MS). Group interventions implemented in community settings have been especially of interest, including tai chi classes. Recently, the authors conducted a preliminary study to examine whether group kick-boxing, which requires more vigorous movements, might be a feasible intervention. Initial findings showed promise and led the authors to pursue a more rigorous follow-up study, with the objective of determining whether a 5-week group kickboxing class improved clinical measures of balance and …

Identifying which muscles are responsible for generating angular momentum has important implications for the diagnosis and treatment of movement disorders.
Pre-Swing Deficits In Forward Propulsion, Swing Initiation And Power Generation By Individual Muscles In Hemiparetic Walking, Carrie L. Peterson, Allison Kinney, Steven A. Kautz, Richard R. Neptune
Pre-Swing Deficits In Forward Propulsion, Swing Initiation And Power Generation By Individual Muscles In Hemiparetic Walking, Carrie L. Peterson, Allison Kinney, Steven A. Kautz, Richard R. Neptune
Mechanical and Aerospace Engineering Faculty Publications
Clinical studies of hemiparetic walking have shown pre-swing abnormalities in the paretic leg suggesting that paretic muscle contributions to important biomechanical walking subtasks are different than those of non-disabled individuals. Three-dimensional forward dynamics simulations of two representative hemiparetic subjects with different levels of walking function classified by self-selected walking speed (i.e., limited community=0.4–0.8 m/s and community walkers=>0.8 m/s) and a speed-matched control were generated to quantify individual muscle contributions to forward propulsion, swing initiation and power generation during the pre-swing phase (i.e., double support phase proceeding toe-off). Simulation analyses identified decreased paretic soleus and gastrocnemius contributions to forward propulsion …
