User Interface Design Recommendations For Small Unmanned Aircraft Systems (Suas), Camilo Jimenez, Caitlin L. Faerevaag, Florian Jentsch Jun 2016

User Interface Design Recommendations For Small Unmanned Aircraft Systems (Suas), Camilo Jimenez, Caitlin L. Faerevaag, Florian Jentsch

International Journal of Aviation, Aeronautics, and Aerospace

The number of small unmanned aircraft systems (sUAS) has dramatically increased in recent years. As a consequence, the number of incidents involving manned and unmanned aircraft has soared. For this reason, the Federal Aviation Administration has released a notice of proposed rulemaking to delineate the operational limitations for sUAS. Many efforts have been introduced to regulate the operations of these systems and educate operators. Despite these efforts, there are no clear standards related to the type of information that should be available to operators, or how this information should be conveyed during flight operations. For this reason we present a …

Why I Don't Weld In Computer Labs, Mark Deegan Jun 2016

Why I Don't Weld In Computer Labs, Mark Deegan

Level 3

Until very recently, like many people in DIT, I had never even seen a welding laboratory. To listen to me now, you’d swear I was raised with a welding torch in my hand. That’s not the case, but when I moved jobs in September 2015, I discovered that DIT runs evening courses in welding, so I decided to sign up. Way back, when I was in college, the greatest threat to life-and-limb was either an alcoholinduced idiot injury, or at worst, the risk of burning myself with a soldering Iron. They get pretty hot, sometimes as hot as 215°C. That …

Energetic Behavior Of Resistive Random-Access Memory Cells, Christopher M. Bisbee May 2016

Energetic Behavior Of Resistive Random-Access Memory Cells, Christopher M. Bisbee

Macalester Journal of Physics and Astronomy

In order to investigate the switching characteristics of Resistive Random Access Memory cells (ReRAM) in terms of their thermodynamic free energy properties, we need to build a number of models that replicate the system. This report contains the models used to investigate filament growth patterns based on different boundary conditions applied to the electrode-filament system. Using Comsol Multiphysics software, we determined that when a fixed voltage is applied to each electrode in the electrode-filament system, we should expect filament dissolution that resets our cells into the High Resistance State (HRS). If we instead fix a set amount of charge on …

Zno Thin Films Generated By Ex-Situ Thermal Oxidation Of Metallic Zn For Photovoltaic Applications, Kovas Zygas May 2016

Zno Thin Films Generated By Ex-Situ Thermal Oxidation Of Metallic Zn For Photovoltaic Applications, Kovas Zygas

Macalester Journal of Physics and Astronomy

ZnO thin films that function as either transparent conducting oxides in solid-state photovoltaic cells or as nanocrystalline dye-absorbers in dye-sensitized solar cells have the potential to reduce the cost of producing electricity from solar energy. Although there exist many methods to produce ZnO thin films, the most economical and practical method may be oxidation of metallic Zn thin films. This research examined the utility of ex-situ thermal oxidation of DC magnetron sputtered Zn thin films in generating useful ZnO thin films for these photovoltaic applications. We annealed Zn thin films in air at 570° C in order to produce ZnO …

Enhanced Adhesion Of Superhydrophobic Zno Surface, Liqiu Zheng Dr., Chan Kwaichow B. May 2016

Enhanced Adhesion Of Superhydrophobic Zno Surface, Liqiu Zheng Dr., Chan Kwaichow B.

Georgia Journal of Science

The superhydrophobicity and the strong solid-liquid adhesion of the dually structured ZnO surface are attributed to the suitable size of microstructure and nanostructure. This phenomenon, so different from the Lotus effect, can be called the Petal effect— the super hydrophobicity and the enhanced solid-liquid adhesion coexist on the same surface. The Cassie impregnating model was proposed to understand the underlying reason.

From Jim Crow To Racial Tolerance: The African-American Experience During Interwar Period Paris, Nicole Schindel May 2016

From Jim Crow To Racial Tolerance: The African-American Experience During Interwar Period Paris, Nicole Schindel

Binghamton University Undergraduate Journal

During World War I, African-American soldiers came to France and discovered the relative diminishment of racial prejudices in the country. Since much of the United States still held racist Jim Crow era laws and prejudices, African-Americans had been barred from the same opportunities as their white counterparts. Because of this, many African- Americans moved to Paris during the interwar period to seek opportunities that were not available to them in the United States. This paper will explore how the less rigid and more nuanced racial ideologies found in Paris, enabled African-Americans to create strong relationships with Parisians and find the …

Womanhood Initiation, Anna Szilagyi May 2016

Womanhood Initiation, Anna Szilagyi

Binghamton University Undergraduate Journal

Womanhood Initiation is a poem I wrote during Maria Gillan's Advanced Poetry Workshop. Professor Gillan is a Professor of English at Binghamton University, and her workshop is unique in that it takes place during three long weekend sessions throughout the semester. This specific poem was inspired by one of Professor Gillan’s writing prompts: “I do not feel like a man/woman yet.” I tend to explore gender in my poetry, specifically girlhood and womanhood. Young women and girls, often put down in United States culture for their vanity and selfishness, are complex, intelligent people and have more to say that should …

Examining Primarily White Institutions Of Higher Education: Black Student Experience In The 1960s, Oluwashola Gbemi May 2016

Examining Primarily White Institutions Of Higher Education: Black Student Experience In The 1960s, Oluwashola Gbemi

Binghamton University Undergraduate Journal

A major outcome of the Civil Rights Act of 1964 was the desegregation of higher-learning institutions. Despite this, there was little change regarding the character and cultural norms of predominantly white institutions (PWIs) of higher learning. In this review of literature discussing the experiences of Black students attending PWIs during the 1960s, I argue that cultural norms such as racial discrimination yielded a detrimental impact on the success and wellbeing of African-American students. While I discuss what quality wellbeing for African-American students entails, I highlight the significance of black student unions to the wellbeing of black students. In order to …

Challenging Linguistic Superiority Through Social Attitudes: Language Complexities Of The Ukrainian Diaspora In The United States, Anna Pinchuk May 2016

Challenging Linguistic Superiority Through Social Attitudes: Language Complexities Of The Ukrainian Diaspora In The United States, Anna Pinchuk

Binghamton University Undergraduate Journal

The English language in the United States has a strong legacy of linguistic imperialism that started with bans on the use of languages spoken by indigenous people in the early 1800s. The assumptions behind those policies were that the English language was civilized and progressive, while all other languages were barbaric and improper. In this paper, I examine how the historic language policies in the United States continue to create barriers in non-native speakers’ success and achievement in social and political spheres. I proceed by discussing the English-only policies and native language bans that started the legacy of English superiority …

Do Natural Disasters Induce More Crime?, Michael Lentini, Plamen Nikolov, Matthew Schwartz May 2016

Do Natural Disasters Induce More Crime?, Michael Lentini, Plamen Nikolov, Matthew Schwartz

Binghamton University Undergraduate Journal

The Indian Ocean Tsunami of 2004 resulted in grave consequences for South East Asia. Indonesia, in particular, had the highest death toll, losing over 150,000 people. Indonesia’s coastal region Aceh was the hardest hit by this disaster. Exploiting exogenous spatial variation at the district level, we use difference-in-difference analysis to estimate the causal effect of the 2004 disaster on subsequent crime rates. We find that after the tsunami, total annual crime rate went down, on average, by 244 crimes per annum.

Fabrication Of A Mems Comb Drive Actuator, Adam Banees May 2016

Fabrication Of A Mems Comb Drive Actuator, Adam Banees

Journal of the Microelectronic Engineering Conference

Comb drives are common in many microelectromechanical systems (MEMS) applications such as gyroscopes, accelerometers and resonators in different fields such as optical communication, wireless communication, and biomedical engineering. A comb drive actuator uses electrostatic forces between the combs to create capacitive actuation. The goal of these devices was to achieve a maximum displacement of the movable combs with the lowest amount of drive voltage. Comb drive actuators were designed and then fabricated. It was found that comb fingers were not defined properly as the fingers were either too skinny or have been completely destroyed. This was due to the STS …

Process Development Challenges Associated With Gallium Nitride Materials, Eric Evangelou May 2016

Process Development Challenges Associated With Gallium Nitride Materials, Eric Evangelou

Journal of the Microelectronic Engineering Conference

While attempting to fabricate low resistance Ohmic contacts to n-GaN and n-AlGaN, processing setbacks necessitated the development of new procedures within the Semiconductor and Microsystems Fabrication Lab (SMFL) at RIT. Photoresist coating recipes usable on GaN pieces were developed for OiR-620 and LOR-5A photoresists, and GaN was etched for the first time on the LAM4600 reactive ion etcher (RIE). The etch was successful, etched GaN at a rate of 187.2 Å/min, and exhibited selectivity between GaN and hard-baked photoresist comparable to an inductively coupled plasma (ICP) etch of the same chemical makeup. An Ohmic Ti to n-GaN contact was fabricated, …

The Utilization Of Mobile Technology For Crime Scene Investigation In The San Francisco Bay Area, Marc Logrande May 2016

The Utilization Of Mobile Technology For Crime Scene Investigation In The San Francisco Bay Area, Marc Logrande

Themis: Research Journal of Justice Studies and Forensic Science

The research presented aims to explore factors affecting the decision to adopt a mobile crime scene investigation application in police departments throughout the San Francisco Bay Area. To accomplish this goal, the mobile technology acceptance model was used in designing a survey for data collection. This model utilizes four categories to interpret the factors that influence a police officer’s decision to accept or reject mobile technologies: performance, security and reliability, management style, and cognitive acceptance. Nine police departments were sampled through a series of in-person and over-the-phone interviews to obtain data regarding factors affecting the adoption of a mobile crime …

Walking Simulator Mechanism, Titus Lungu, Igor Tachynskyy, Omri Tayyara

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

This paper presents the design, simulation, and kinematic evaluation of a mechanism aimed at simulating both the motion and ground reaction forces produced by a human foot while walking. Such a mechanism can be used to test the durability of shoes through life cycle analysis. In attempting to mimic the physical motion of the human foot as closely as possible, the forces experienced by the human foot were also accurately replicated through the incorporation of a non-stationary testing platform. As is shown in the paper, this testing environment allows for simple adjustments to be made in order to simulate different …

A Cyber-Physical System, Andrew Davis, Dustin Bowe, Josiah Nagel May 2016

A Cyber-Physical System, Andrew Davis, Dustin Bowe, Josiah Nagel

Montview Journal of Research & Scholarship

The team was tasked with the creation of an autonomous cyber-physical system that could be continually developed as a post-capstone class by future STEM students and as a means to teach future engineering students. The strict definition of a cyber-physical system is a computation machine that networks with an embedded computer that performs a physical function. The autonomous aspect was achieved through two sonic sensors to monitor object distances in order to avoid walls and obstacles. The integrated system was based on the Intel Edison computation module. A primary goal for future addition is automation capabilities and machine learning applications.
