A Brief Survey Of The Biblical Integration Of Engineering And Missions With Emphasis On Appropriate Technologies, Frederick G. Harmon 2017 Cedarville University

A Brief Survey Of The Biblical Integration Of Engineering And Missions With Emphasis On Appropriate Technologies, Frederick G. Harmon

Christian Engineering Conference

A Biblical foundation for the integration of engineering and missions, an overview of appropriate technology in a Christian context, a survey of projects at other Christian engineering programs, and proposed engineering projects are discussed for remote areas and developing countries. At the core of the Biblical integration of engineering and missions is the desire to use engineering skills and resources to assist others, especially those in the Christian family, improve their lives, help them obtain Biblical information, and encourage personal responsibility. Engineering topics are proposed that will help people gain access to information, improve agricultural methods, improve their health, and ...


Integrally Christian Engineering Scholarship: A Case Study, Justin R. Vander Werff 2017 Dordt College

Integrally Christian Engineering Scholarship: A Case Study, Justin R. Vander Werff

Christian Engineering Conference

Engineering programs at Christian colleges typically focus primarily on undergraduate education. Likewise, faculty members drawn to Christian engineering education tend to have a strong desire to disciple young men and women in what it means to be faithful Christ followers in engineering. Consequently, engineering faculty tend to work long and hard to provide a solid education experience, leaving little time for anything else. However, institutional demands on faculty typically extend far past teaching, and one area that inevitably pops up in growing Christian engineering programs is research and scholarship. What is the place of research in a Christian engineering program ...


Philosophy Of Teaching And Student And Peer Mentorship: A Christian Perspective, Scott J. Anson 2017 LeTourneau University

Philosophy Of Teaching And Student And Peer Mentorship: A Christian Perspective, Scott J. Anson

Christian Engineering Conference

As Professors our students have the multifaceted status of being 1) our customers, 2) our product and 3) our future colleagues. In addition as Christians, they are our brothers and sisters in Christ or those we influence for His glory. As customers they have a choice where to pursue their education and have expectations. Some expectations are reasonable, some we need to recalibrate for them. As our product, their professional growth and abilities are to varying degrees a result of, and to a very large degree, a reflection of us and our institutions. As graduates employed in an industry we ...


Institutional Differences In The Education Of Engineering And Computing Students About Ethics And Societal Impacts, Angela Bielefeldt, Madeline Polmear, Daniel Knight, Christoppher Swan, Nathan Canney 2017 University of Colorado at Boulder

Institutional Differences In The Education Of Engineering And Computing Students About Ethics And Societal Impacts, Angela Bielefeldt, Madeline Polmear, Daniel Knight, Christoppher Swan, Nathan Canney

Christian Engineering Conference

This study explored the extent to which faculty report teaching engineering and computing students about ethics and societal impacts (ESI) in courses and via co-curricular activities. The research questions were to determine if there were differences in the topics, teaching methods, assessment methods, and satisfaction with ESI instruction between faculty from religiously-affiliated (RA) and non-religiously affiliated (NRA) institutions. A national survey was conducted, with about 1400 responses. This included 122 faculty from 60 RA institutions (across 17 denominations/faiths). Chi-square tests evaluated statistically significant differences (p


Theology And Engineering Practice: Models Of Reality, William M. Jordan 2017 Baylor University

Theology And Engineering Practice: Models Of Reality, William M. Jordan

Christian Engineering Conference

To a Christian engineer both faith and engineering practice are very important. As we work through what we believe about God and how we practice engineering, we find that they have something important in common. Both systematic theology and engineering practice are approximations in our attempts to understand reality.

When theologians attempt to systematize the faith, they are coming up with human models of how they see God acting in human history. When engineers design a new product, they use models of how materials act when they have various forces applied to them.

For example, in discussing end times theologians ...


On The Significance Of The Biography And Thought Of Pilgram Marpeck For A Responsible Engineering Perspective, Karl Heinz Kienitz 2017 Instituto Tecnologico de Aeronautica

On The Significance Of The Biography And Thought Of Pilgram Marpeck For A Responsible Engineering Perspective, Karl Heinz Kienitz

Christian Engineering Conference

In the general scope of an aspirational approach to engineering practice and ethics, this article follows the paradigm of learning from biography and presents Pilgram Marpeck, an engineer and Anabaptist reformer of the 16th century, as a possible early role model for the engineering professional. A biographical review of his life and all-encompassing participation in the society of his time is followed by a self-contained summary of his thought on selected topics. When considering the bearing of these on engineering ethics and practice, Marpeck's thought and several of his concerns are found of current relevance.

Phonon Dispersion And Relaxation Time In Uranium Dioxide, Dallin Parkinson 2017 Utah State University

Phonon Dispersion And Relaxation Time In Uranium Dioxide, Dallin Parkinson

All Graduate Plan B and other Reports

Phonon dispersion branches are used to obtain an effective relaxation time to calculate thermal conductivity of Uranium Dioxide (UO2). The method presented closely follows that of Deskins’ phonon-phonon interaction that uses a three-phonon process which satisfies momentum and energy conservation. All phonon branches including longitudinal acoustic, transverse acoustic, longitudinal optical and transverse optical are considered in the calculation of the relaxation time.

After one phonon is identified, a scan is initiated to test all phonon combinations that will satisfy the conservation equations. When the scan identifies a valid three-phonon combination a relaxation time is calculated for that combination. All ...


The Influence Of Push-Off Timing In A Robotic Ankle-Foot Prosthesis On The Energetics And Mechanics Of Walking., Philippe Malcolm, Roberto E. Quesada, Joshua M. Caputo, Steven H. Collins 2017 Ghent University

The Influence Of Push-Off Timing In A Robotic Ankle-Foot Prosthesis On The Energetics And Mechanics Of Walking., Philippe Malcolm, Roberto E. Quesada, Joshua M. Caputo, Steven H. Collins

Philippe Malcolm

BACKGROUND: Robotic ankle-foot prostheses that provide net positive push-off work can reduce the metabolic rate of walking for individuals with amputation, but benefits might be sensitive to push-off timing. Simple walking models suggest that preemptive push-off reduces center-of-mass work, possibly reducing metabolic rate. Studies with bilateral exoskeletons have found that push-off beginning before leading leg contact minimizes metabolic rate, but timing was not varied independently from push-off work, and the effects of push-off timing on biomechanics were not measured. Most lower-limb amputations are unilateral, which could also affect optimal timing. The goal of this study was to vary the timing ...

Functions and visualization methods included in openair package make scrutiny of large data sets easier and less time consuming. They allow for analysis of measurement data with the determination of general relationships between parameters, additional complex spatial analyses for back trajectories, and ...


The Impact Of Three Interfaces For 360-Degree Video On Spatial Cognition, Wutthigrai Boonsuk, Stephen B. Gilbert, Jonathan W. Kelly 2017 Iowa State University

The Impact Of Three Interfaces For 360-Degree Video On Spatial Cognition, Wutthigrai Boonsuk, Stephen B. Gilbert, Jonathan W. Kelly

Jonathan W. Kelly

In this paper, we describe an experiment designed to evaluate the effectiveness of three interfaces for surveillance or remote control using live 360-degree video feeds from a person or vehicle in the field. Video feeds are simulated using a game engine. While locating targets within a 3D terrain using a 2D 360-degree interface, participants indicated perceived egocentric directions to targets and later placed targets on an overhead view of the terrain. Interfaces were compared based on target finding and map placement performance. Results suggest 1) non-seamless interfaces with visual boundaries facilitate spatial understanding, 2) correct perception of self-to-object relationships is ...

Assessing Multiple Participant View Positioning In Virtual Reality-Based Training, Jonathan W. Kelly, Eliot Winer, Stephen B. Gilbert, Michael Curtis, Eduardo Rubio, Ken Kopecky, Joseph Scott Holub, Julio De La Cruz

Jonathan W. Kelly

As cost, time, and other challenging resource requirements are placed on U.S. Joint forces training, the role of simulations will play an even greater role than it does today. To effectively aid a Warfighter in gaining critical skills and to assess the proficiency of those skills, computer-based training must advance beyond traditional desktop simulations and monoscopic projection technology. Virtual Reality (VR) based training has been proven in fields such as medical and engineering to increase a trainee’s level of immersion, and increase training performance in several metrics including accuracy and efficiency, while simultaneously decreasing cost. Warfighter training offers ...


Comparing Training Performance With Vibrotactile Hit Alerts Vs. Audio Alerts, Stephen B. Gilbert, Anthony Civitate, Jonathan W. Kelly, Frederick Thompson, Alisha Smith, Ken Kopecky, Eliot Winer, Julio de la Cruz 2017 Iowa State University

Comparing Training Performance With Vibrotactile Hit Alerts Vs. Audio Alerts, Stephen B. Gilbert, Anthony Civitate, Jonathan W. Kelly, Frederick Thompson, Alisha Smith, Ken Kopecky, Eliot Winer, Julio De La Cruz

Jonathan W. Kelly

Live, virtual, and constructive training that integrates dismounted warfighter training with convoy training, pilot training, and other systems has been demonstrated to reduce training time, and studies have shown that a high level of immersion and the illusion of presence in a VR environment contribute to this success. However, current force-on-force training simulators lack one major quality that is needed to impart this strong sense of presence for warfighters: the consequence of getting shot.

Simulated return-fire systems have been developed for different purposes including military, police and entertainment. Some use projectiles, but that approach is usually limited to a shoot ...


Loss Model For Gallium Nitride Dc-Dc Buck Converter, Rushi P. Patel 2017 Mississippi State University

Loss Model For Gallium Nitride Dc-Dc Buck Converter, Rushi P. Patel

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

In recent years, more research has been done on Enhancement Mode Gallium Nitride (eGaN) converters, as the world is moving towards more power efficient converters. Power converters play a major role in efficiently controlling and converting electric energy used by machines, systems, and everyday products. The process to make converters more efficient was complicated and slow in the twentieth century. One of the important aspects in power electronics is to evaluate different losses and minimize losses to achieve high efficiency of the converter. With help of simulation tools such as MATLAB and LTspice, this process has become much faster and ...


Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin 2017 University of Tennessee, Knoxville

Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

Tractor rollovers are a leading cause of death in the agricultural industry. While rollovers continue to happen, Roll-Over Protective Structures (ROPS) have shown great ability to prevent or reduce the casualties and injuries associated with rollover events. One authority on the subject even goes so far as to claim that “that fatality rates due to tractor overturns could be reduced by a minimum of 71% if all tractors in the U.S. were equipped with ROPS,” (NIOSH, 2009). The potential of this promising statistic has been devalued slightly due to the misapplication of foldable ROPS by leaving the ROPS in ...


Streambank Erosion Mapping On The Nottoway River Using Gps-Based Above-Water Video, Emine Fidan 2017 University of Tennessee, Knoxville

Streambank Erosion Mapping On The Nottoway River Using Gps-Based Above-Water Video, Emine Fidan

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

This project concerns the development of streambank erosion maps on military installations utilizing GPS-based above-water video mapping and image georeferencing techniques. The river mapped was the Nottoway River at the Fort Pickett military installation on October 10-11, 2015. Kayak-mounted above-water cameras were utilized to capture georeferenced images of streambank erosion. These GIS-based erosion classifications were utilized to develop erosion maps for determining streambank erosion conditions along the river. Areas of high erosion were identified as about two percent of the river (2167 ft. of streambank length). These maps allow for the opportunity to revisit the sites to determine changes in ...

A Hardware One-Time Pad Prototype Generator For Localising Cloud Security, Paul Tobin, Lee Tobin, Michael mcKeever, Jonathan Blackledge Professor 2017 Dublin Institute of Technology

A Hardware One-Time Pad Prototype Generator For Localising Cloud Security, Paul Tobin, Lee Tobin, Michael Mckeever, Jonathan Blackledge Professor

Conference papers

In this paper, we examine a system for encrypting data before storing in the Cloud. Adopting this system gives excellent security to stored data and complete control for accessing data by the client at different locations. The motivation for developing this personal encryption came about because of poor Cloud security and doubts over the safety of public encryption algorithms which might contain backdoors. However, side-channel attacks and other unwanted third-party interventions in Cloud security, probably contribute more to the poor security record history. These factors led to the development of a prototype for personalising security locally which defeats cryptanalysis. The ...
