Discrimination Against Women In The Field Of Engineering, Julia Weber

Undergraduate Voices

This article focuses on the position of women in the field of engineering, specifically why the field is male-dominated and why this condition should change. When I state the field is male-dominated, I am addressing both the proportion of men in the field in comparison to women and discrimination towards women in the workplace.

Throughout this article, I will be focusing on women in the field of engineering. I will look into why the field is so male-dominated (Chu, 2005; Hunt, 2016; Ramirez & Wotipka, 2001) and how this has begun to change over time (Hill, Corbett, & St Rose, 2010; Morgan, 1992; Ramirez & Wotipka, 2001; Scandura & Ragins, 1993; Torre, 2014). Additionally, I will look into whether or not women within the ...

Improving Spatial Visualization Abilities Using 3d Printed Blocks, Vanessa Lebow, Michelle Bernhardt-Barry, Jyotishka Datta

Civil Engineering Undergraduate Honors Theses

Spatial visualization abilities have been shown to be a key predictor of success in science, technology, engineering, and math fields. Past research has revealed that women and underrepresented minorities tend to lag behind in spatial visual abilities, however, research has also shown that these skills can be improved with guided practice. This study seeks to examine whether 3D printed aids help spatial visual retention in 6th graders. A modified Purdue spatial visualization test was used as the assessment standard. Students’ mental rotation abilities were assessed before and after the 3D printed aids were administered. Data was collected from five different ...

Baseline Data From Servo Motors In A Robotic Arm For Autonomous Machine Fault Diagnosis, Jacob Brown

Mechanical Engineering Undergraduate Honors Theses

Fault diagnosis can prolong the life of machines if potential sources of failure are discovered and corrected before they occur. Supervised machine learning, or the use of training data to enable machines to discover these faults on their own, makes failure prevention much easier. The focus of this thesis is to investigate the feasibility of creating datasets of various faults at both the component and system level for a servomotor and a compatible robotic arm, such that this data can be used in machine learning algorithms for fault diagnosis. The faults induced at the component level in different servomotors include ...

Development Of A Model To Predict The Likelihood Of Complaints Due To Assorted Tone-In-Noise Combinations, Joonhee Lee, Lily M. Wang

Architectural Engineering -- Faculty Publications

This paper develops a model to predict if listeners would be likely to complain due to annoyance when exposed to a certain noise signal with a prominent tone, such as those commonly produced by heating, ventilation, and air-conditioning systems. Twenty participants completed digit span tasks while exposed in a controlled lab to noise signals with differing levels of tones, ranging from 125 to 1000 Hz, and overall loudness. After completing the digit span tasks under each noise signal, from which task accuracy and speed of completion were captured, subjects were asked to rate level of annoyance and indicate the likelihood ...

Compressed Air Systems Evaluation And Improvement, Lukas Swoboda

Honors Theses

This project was centered on recommending a new air compressor system for the Fluid System Connectors division of Parker Hannifin in Otsego, Michigan. The recommended compressor for the plant is a 250hp variable speed drive Ingersoll Rand Compressor. It is recommended that this compressor, along with two 35hp compressors already purchased by Parker be tied together using an automated system. In addition to the compressor, a flow controller was recommended to be implemented into the system.

Given that leaks are also a problem in the system, it is recommended that the majority of air leaks in the system be fixed ...

An Investigation Of The Efficacy Of Corn Cob Hemicellulose As A Gas Barrier And Dry Strength Agent On Previously Uncoated Linerboard, Zachary Witherspoon

Honors Theses

Two types of xylan, water soluble and insoluble, were extracted from corn cobs and made into liquid coatings and applied to uncoated linerboard with a fine, #8 Meyer rod, with the intention of creating a gas barrier and increasing strength properties. The xylan coatings were plasticized with sorbitol and crosslinked with citric acid, and the crosslinking reaction catalyzed with sodium hypophosphite. A 1% konjac glucomannan comparison coating was created (with the same plasticizer and crosslinker) to serve as an alternative coating based on previous research in the department, but it failed as a paper coating due to the presence of ...

Gradel, Emily R. Wolf, Christopher D. Brauns Ii, Timothy G. Smith Ii, Emmett Z. Budd

The Research and Scholarship Symposium

A major problem facing Computer Science faculty members at Cedarville University is grading student assignments. Specifically, grading programming assignments can be a repetitive, time-consuming process which makes it prime for automation. Professors need a web application that takes student code, compiles it, and compares the output to what the professors provides as correct. Gradel, a senior design project, allows students to submit their code online and receive instant feedback based on professor-designed test cases. Furthermore, professors need to be able to keep track of what grades students earn on their projects, which is functionality Gradel provides. In addition to allowing ...

The Eco-Smart Can V2.0, Darack B. Nanto

Appalachian Student Research Forum

I noticed that the workers had the same itinerary when emptying trashcans, meanwhile trashcans needed urgently to be emptied. Traditionally, ETSU maintenance operate on daily routes to pick trash on designated time, regardless the level of the containers. This leads to overflown trashcan in busy areas or during rush hours in certain areas. This overflown trashcan result in an unclean environment for the community and an unpleasant look of our beautiful campus. The time, resources and labor invested in collecting the trash could be saved. Therefore, I decided to use the Internet of Things (IoT) to create a device that ...

Pressure Transient Techniques For Continuous Monitoring Of Co2 Storage/Eor, Nam Hoang Tran

The study investigated both differences in severity selection given varying amounts of experience as well as any association between severity selection and the provided input information. The main goal of the research was to investigate the impact of data quality on severity selection and to identify factors ...

Deep Gaze Velocity Analysis During Mammographic Reading For Biometric Identification Of Radiologists, Hong-Jun Yoon, Folami Alamudun, Kathy Hudson, Garnetta Morin-Ducote, Georgia Tourassi

Journal of Human Performance in Extreme Environments

Several studies have confirmed that the gaze velocity of the human eye can be utilized as a behavioral biometric or personalized biomarker. In this study, we leverage the local feature representation capacity of convolutional neural networks (CNNs) for eye gaze velocity analysis as the basis for biometric identification of radiologists performing breast cancer screening. Using gaze data collected from 10 radiologists reading 100 mammograms of various diagnoses, we compared the performance of a CNN-based classification algorithm with two deep learning classifiers, deep neural network and deep belief network, and a previously presented hidden Markov model classifier. The study showed that ...

Simultaneous Electrical And Mechanical Resonance Drive For Large Signal Amplification Of Micro Resonators, M. H. Hasan, F. M. Alsaleem, N. Jaber, M. A. A. Hafiz, M. I. Younis

Architectural Engineering -- Faculty Publications

Achieving large signal-noise ratio using low levels of excitation signal is key requirement for practical applications of micro and nano electromechanical resonators. In this work, we introduce the double electromechanical resonance drive concept to achieve an order-of-magnitude dynamic signal amplification in micro resonators. The concept relies on simultaneously activating the micro-resonator mechanical and electrical resonance frequencies. We report an input voltage amplification up to 15 times for a micro-resonator when its electrical resonance is tuned to match the mechanical resonance that leads to dynamic signal amplification in air (Quality factor enhancement). Furthermore, using a multi-frequency excitation technique, input voltage and ...

Influence Of Atmospheric Clearness On Pdlc Switchable Glazing Transmission, Aritra Ghosh, Brian Norton, Tapas K. Mallick

Articles

Electrically activated switchable polymer dispersed liquid crystal (PDLC) is suitable for adaptive windows. A particular type requires 20V to become 71% transparent while in the absence of power it is 27% transparent. Glazing transmission changes with light incident angle. As the clearness of a sky changes the fraction changes alter of direct insolation (that has an azimuthally changing incident) and diffuse insolation (that has a largely constant incident). Thus, the effective overall incident angle determining the glazing transmittance also changes. In this work for the first time, the variation of PDLC glazing transmission with clearness index has been investigated.

Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg

Architectural Engineering -- Faculty Publications

Disputes are common in the construction industry and lead to unnecessary cost and schedule overruns in projects. It is commonly believed that owners’ early decisions regarding the selection of delivery methods, procurement methods, and contract types impact the frequency and severity of project disputes; however, no previous study has empirically tested this hypothesis, particularly in highway public projects. Therefore, this study empirically investigated the impact of owners’ early decisions regarding project organization (i.e., delivery methods, procurement, and contract types) on performance measures (e.g., cost and schedule growth), specifically dispute performance metrics (e.g., frequency and severity of disputes ...

Design And Evaluation Of Auditory-Supported Air Gesture Controls In Vehicles, Jason Sterkenburg

Dissertations, Master's Theses and Master's Reports

The number of visual distraction-caused crashes highlights a need for non-visual information displays in vehicles. Auditory-supported air gesture controls could fill that need. This dissertation covers four experiments that aim to explore the design auditory-supported air gesture system and examine its real-world influence on driving performance. The first three experiments compared different prototype gesture control designs as participants used the systems in a driving simulator. The fourth experiment sought to answer more basic questions about how auditory displays influence performance in target acquisition tasks. Results from experiment 1 offered optimism for the potential of auditory-supported displays for navigating simple menus ...

Rapid And Damage-Free Outgassing Of Implanted Helium From Amorphous Silicon Oxycarbide, Qing Su, Hepeng Ding, Lloyd Price, Lin Shao, Jonathan A. Hinks, Graeme Greaves, Stephen E. Donnelly, Michael J. Demkowicz, Michael Nastasi

NCESR Publications and Research

Damage caused by implanted helium (He) is a major concern for material performance in future nuclear reactors. We use a combination of experiments and modeling to demonstrate that amorphous silicon oxycarbide (SiOC) is immune to He-induced damage. By contrast with other solids, where implanted He becomes immobilized in nanometer-scale precipitates, He in SiOC remains in solution and outgasses from the material via atomic-scale diffusion without damaging its free surfaces. Furthermore, the behavior of He in SiOC is not sensitive to the exact concentration of carbon and hydrogen in this material, indicating that the composition of SiOC may be tuned to ...
