Design And Assembly Of A Spring-Powered Engine Starter Prototype
Design And Assembly Of A Spring-Powered Engine Starter Prototype
Stander Symposium Projects
Automotive starting systems require substantial amounts of mechanical energy in a short period of time. Lead-acid batteries have historically provided that energy through a starter motor. Springs have been identified as an alternative energy storage medium and are well suited to engine-starting applications due to their ability to rapidly deliver substantial mechanical power and their long service life. This project involves the development of a prototype of a spring-powered starter for a motorcycle engine. The focus was on the design and assembly of the complete system, including the design challenge of interfacing the starting mechanism with the motorcycle, designing the …
Design And Characterization Of Photo-Responsive Supramolecular Aggregates
Design And Characterization Of Photo-Responsive Supramolecular Aggregates
Stander Symposium Projects
A supramolecular assembly is a complex of molecules held together by noncovalent interactions. The process by which supramolecular assemblies are formed is called “molecular self-assembly”, during which the molecules spontaneously aggregate in a specific manner, acquiring new properties. Incorporating photoisomerizable molecules into supramolecular assemblies offers considerable opportunities in developing new smart materials. Using UV-Vis and CD spectroscopy, we explored the propensity for a dicarboxylic acid derivatized azobenzene photoswitch (ADA) to form supramolecular aggregates and investigated the photochemical behavior of the system. ADA was shown to undergo cis-trans isomerization when irradiated in aqueous solution with visible and UV light. Upon reduction …
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 …

Mis, Om And Decision Sciences, Political Science
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, …
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 …
