Genesis Of The Creation Research Engineering Association, John Swan

Proceedings of the International Conference on Creationism

In the last 20 to 30 years two things have come together to create a huge opportunity in the creation/Intelligent Design (ID) movements:

• [input 1] The first is the tremendous volume of scientific knowledge ranging from genomics/biology, earth sciences (i.e. geophysics, geology…), and astronomy/cosmos.
• [input 2] The second item intersecting with the first is pervasive computing capability that was hardly dreamed of 30 years ago.
• [result] A gap which represents a huge opportunity for creation research, is the need for a much wider application of engineering resources to creation science research in the forms of simulations, numerical analysis and similar …

Fe Analysis Of Tsunami Generation During The Genesis Flood, Tim Lewis, John Baumgardner

Proceedings of the International Conference on Creationism

Within the framework of catastrophic plate tectonics, large tsunamis are a plausible mechanism for producing fossil-bearing sediments of the Flood rock record. The focus of this research is to model the behavior of an overriding slab in response to a rapidly subducting plate with the aim of understanding in more detail the tsunami generation process. Key to this process is the locking and unlocking of the overriding and subducting slabs. The unlocking results in the rapid rise of the sea bottom and generation of a tsunami. Several key questions arise in this context that the model seeks to answer. What …

Modeling The Process Of Rapid Geomagnetic Reversal During The Genesis Flood, Eric T. Katzaman, John Baumgardner

Proceedings of the International Conference on Creationism

Remnant magnetization in the Earth’s igneous rocks document that the Earth’s magnetic field reversed its polarity many times during the Genesis Flood. Previous creationist research has argued that strong convective buoyancy within the Earth’s liquid outer core during the Flood can cause the expulsion of magnetic flux outward from the core into the overlying mantle which produces rapid reversals of the Earth’s surface dipolar magnetic field. This poster reports the status of our efforts to model this dynamic process in 3D spherical geometry using a magnetohydrodynamic numerical solver.

Dynamic Recrystallization And Grain Size Effects On Catastrophic Motion Of The Earth’S Mantle During The Flood: Advancement Of Material Models, Heechen Cho, John Baumgardner, Maria Lee, Caleb Miller, Mark Horstemeyer

Proceedings of the International Conference on Creationism

This presentation reports a numerical study to investigate the mechanical effects of dynamic recrystallization (DRX) and the grain size on the speed of flow of rock inside the earth’s solid mantle during the Genesis Flood. The strength, or viscosity, of its constituent minerals is key to understanding and modeling the dynamics of the mantle correctly. A mineral’s strength is strongly influenced by the crystal size, its lattice defects (vacancies and dislocations), and other microscale and crystal-scale phenomena. Since the viscosity difference of the earth’s deep mantle between the present day and during the Flood cataclysm is approximately 10 orders of …

Bacterial Chemotaxis Control Illustrates An Engineering Framework In The Creation Model, James D. Johansen

Proceedings of the International Conference on Creationism

This paper shows how biological design in bacteria chemotaxis control shows architectural design features that are found in many areas of biological life that reflect an engineering framework found in the creation model. The study highlights the bacteria chemotaxis control process utilizing the System Modeling Language (SysML) to leverage well-defined and proven engineering tools for architecting, analyzing, and refining complex systems. It first introduces SysML, and the advantages model-based systems engineering (MBSE) has for capturing system architecture and allowing for ongoing assessment of how biological system operates and the clarification of how much model detail is required to reveal a …

Tapping The Hourglass: Disequilibrium Relaxation Following Accelerated Nuclear Decay, Nathan Mogk

Proceedings of the International Conference on Creationism

In 2005, the Radioisotopes and the Age of The Earth (RATE) research initiative published compelling evidence for at least one episode of past radioactive decay which was accelerated by orders of magnitude compared with the rates measured in recent years. Constancy of radioactive decay rates is a central assumption in radiometric dating. Accelerated nuclear decay (AND) causes systematic change in the results of radiometric dating beyond the in situ above normal accumulation of daughter products. This includes relaxation of magma reservoirs to equilibrium and excessive inheritance arising from disequilibrium excesses of daughter products of greater order than crystal-melt partition ratios. …

Language, Coded Instructions And The Interaction With Thermodynamics, Andy C. Mcintosh

Proceedings of the International Conference on Creationism

The theme of the 9th ICC is Developing and Systematizing the Creation Model of Origins. Following this theme, the proposed paper seeks to establish a rigorous and systematic approach to the important area of information and its interface with the substrate on which the information is expressed. This must first involve the understanding of the laws of thermodynamics not only for isolated systems but for closed (where only energy is allowed to cross the boundary) and open systems (where both matter and energy are allowed to cross the boundary). This is particularly an issue with the second law of …

Cause Of Large Post-Flood Jump In Earth's Carbon 14, D Russell Humphreys

Proceedings of the International Conference on Creationism

Accelerated fusion in the Sun during the flood caused large post-flood jump in Earth’s ¹⁴C

D. Russell Humphreys

Creationists studying carbon-14 dating are generally aware of the need to have a large increase in Earth’s ¹⁴C/C ratio during the post-flood Ice Age (Oard, 2021), from about 0.5% of today’s ratio in fossils (Baumgardner, 2005) to more than 95% of today’s ratio by the time of Moses, 1500 B.C. Today cosmic-ray-generated neutrons hitting ¹⁴N nuclei in the atmosphere produce most of the ¹⁴C. With today’s influx of cosmic rays, it would take about 14,000 years to build …

Genealogical Vs Phylogenetic Mutation Rates: Answering A Challenge, Robert Carter

Proceedings of the International Conference on Creationism

There is a discrepancy between the mutation rate we can measure today and the rate at which evolution is supposed to have proceeded. The former is sometimes called the genealogical mutation rate, for it is obtained by comparing individuals whom we know to be related. The latter is sometimes called the phylogenetic mutation rate. It is calculated by counting the fixed differences between two species and dividing by the estimated time since their common ancestor. Genealogical mutation rates are generally several orders of magnitude faster than phylogenetic estimates. This causes problems for the evolutionary model. For example, using the genealogical …

A Rapid Ice Age And Transition To Ice Sheet Growth, Steven M. Gollmer

Proceedings of the International Conference on Creationism

For the past half-century, creationists have explored different explanations for glacial erosion features across the Northern Hemisphere. The best explanation to date is a single post-flood ice age with multiple surges. The challenge with this model is the limited time available between the end of the Flood and the time of Abraham, which appears to be post ice age. Oard (1979) proposed a short post-flood ice age developing due to warm oceans, volcanic aerosols, and barren surfaces. Performing computer climate simulations, Spelman (1996), Vardiman (1998), Gollmer (2013), and Gollmer (2018) verified that enhance precipitation occurs at higher latitudes due to …

Human Brain Function Above All Other And The Creation Model, James D. Johansen

Proceedings of the International Conference on Creationism

The human brain functions at a level beyond any other brain in all of creation. With mankind being made in the image of God, there must be signatures of this fact in its design. Modeling the human brain that develops an architectural framework offers the potential to unpack this reality. This premise offers a rich area to explore that expands the creation model to capture the engineering framework God used in creation. This paper will focus on brain neurons and neural networks using systems engineering modeling tools.

The systems modeling language (SysML) will be used to capture a model of …

Measuring Academic Integrity Perceptions And The Correlation With Ethical Reasoning, M. Green, David Dittenber

Engineering and Computer Science Faculty Publications

Here we share findings of student and faculty perceptions of academic integrity practices at two institutions, gaps between these perceptions, and how these perceptions may correlate with markers of ethical engineering identity formation. We hypothesize that a climate of informed ethical practices surrounding academic integrity supports higher levels of student outcomes on an ethical reasoning assessment. As part of this mixed methods study, engineering students indicated their perceptions via a confidential survey of how well faculty fulfill several best practices for supporting academic integrity: articulating clear policies, preventing cheating, and promoting the value of integrity in class. Students also self-reported …

Forming Congnitive Connections: Desktop Learning Modules, Structural Analysis Software, And Full-Scale Structures, David Dittenber, Luke Thomas Fredette

Engineering and Computer Science Faculty Publications

One of the biggest challenges in teaching civil engineering students a theory-intensive course like structural analysis is helping students make the connection between the engineering mechanics taught at the front of the room and how those concepts define the real behavior of actual engineered structures. Absent this connection, students will often learn how to successfully perform the mathematical functions on their homework assignments but lack confidence in their ability to apply the same concepts to the analysis or design of an actual structure. Common ways to try to provide this real-world application of structural analysis principles include the use of …

Experimental And Numerical Study Of Drag Reduction On Elliptical Cylinders Using Surface Grooves, Michael T. Brocker, David J. Mcdonell, Drake L. Pensworth, Joshua J. Swimm

Channels: Where Disciplines Meet

Drag reduction on an object subject to external flow remains a topic of interest due to a wide range of applications. Previous studies showed that grooves on the surface of a circular cylinder lead to drag reduction, which had thus been applied to save energy in various implementations. In the present study, the effects of longitudinal surface grooves with respect to drag reduction on circular and elliptical cylinders were experimentally explored through resin additive manufacturing and a wind tunnel. Significant drag reduction originated by surface grooves was observed. In conjunction with experimental investigations, numerical analyses were performed with computational fluid …

Bionic Hand Team, Christopher T. Rossiter, David J. Bogacz, Carly J. Ulrich

Scholars Symposium

The project goal is to design a low cost prosthetic hand controlled by a PIC18F25K22 microcontroller that will allow the user to perform simple tasks that require a greater dexterity than what a mechanical prosthetic can deliver. The digits of the prosthetic will be contracted or relaxed using electromyographic signals measured by electrodes on a single muscle group. Grip settings, which define the open and closed position for each digit, are used for the control of the hand. This allows common actions, such as grabbing a door handle or pencil, to be accomplished with readings from one muscle group instead …

Autonomous Golf Cart, Anson Allard, Joel Beckmeyer, Emma Burgess, Daniel Garcia, Jacob Lysack, Daniel Parker

Scholars Symposium

Cedarville University’s Autonomous Golf Cart Senior Design Project’s mission is to provide engineering students with hands on experience with industry standard intelligent vehicle technologies, solve open-ended, multi-dimensional problems, and provide an autonomous transportation service to the greater campus community. Our autonomous technology will share the sidewalks; therefore, the public image of our autonomous routing service is critically linked with its technical performance. The autonomous golf cart has two major design areas: the cart’s hardware and its software. Within hardware, our team created functional braking and an H-Bridge for reversing. Within software, our team moved the codebase to a new software …

Collaborative Development Of Spatial Audio Virtual Environments, George V. Landon, Austin K. Jaquith

Engineering and Computer Science Faculty Publications

Access to the newest features of Virtual Reality headsets has become increasingly more accessible to student developers in recent years. Manufacturers are competing to support all available device features not just through their Software Development Kits (SDKs), but also integrated into industry-standard game engines. One particular feature, spatial sound, can now be deployed without directly accessing the SDK but instead modifying deployment settings and selecting checkboxes. This accessibility to new VR developers has opened up new opportunities for inter-disciplinary collaborations within constrained development cycles like an academic semester.

Low Cost Vehicular Autonomy Using Radar And Gps, Nathan Jessurun, Ryan Gordon, Danielle Fredette

The Research and Scholarship Symposium (2013-2019)

This presentation describes a subset of the systems devised for this year's autonomous golf cart senior design project. Our goal is to explore the possibilities of low cost autonomy using only radar and GPS for environmental sensing and navigation. Although autonomous and semi-autonomous ground vehicles are a relatively new reality, prototypes have been a subject of engineering research for decades, often utilizing an array of sensors and sensor fusion techniques. State of the art autonomous ground vehicle prototypes typically use a combination of LIDAR and other distance sensors (such as radar or sonar) as well as cameras and GPS, sometimes …

Rotating Scatter Mask Optimization For Gamma Source Direction Identification, Darren E. Holland, James E. Blevins, Larry W. Burggraf, Buckley E. O'Day

Engineering and Computer Science Faculty Publications

Rotating scattering masks have shown promise as an inexpensive, lightweight method with a large field-of-view for identifying the direction of a gamma emitting source or sources. However, further examination of the current rotating scattering mask design shows that changing the geometry may improve the identification by reducing or eliminating degenerate solutions and lower required count times. These changes should produce more linearly independent characteristics for the mask, resulting in a decrease in the mis-identification probability. Three approaches are introduced to generate alternative mask geometries. The eigenvector method uses a spring–mass system to create a geometry basis. The binary approach uses …

The Extraordinary Design Of The Bombardier Beetle: A Classic Example Of Biomimetics, Andy C. Mcintosh, Joseph Lawrence

Proceedings of the International Conference on Creationism

The innocuous looking bombardier beetle is one of the most remarkable creatures in the insect world. This tiny insect (1-1.5 cms long) is able to fight off any spider, frog, ant or bird that comes too close, by blasting the attacker with a powerful jet of hot, toxic fluid. Furthermore, the beetle can aim its weapon in any direction (even over its head) with pinpoint accuracy, and can reach distances of up to 20 cm with its spray. The bombardier beetle is rare in Europe but common in Africa, Asia and the warmer parts of the Americas, and in order …
