E-shrines raise important questions about the overlap between digital and physical spaces within Catholic practice. Attuned to the context of the COVID-19 pandemic, this chapter argues that digital devotion has become an increasingly important practice that has pushed Marian shrines …

A Bi-Invariant Approach To Approximate Motion Synthesis Of Planar Four-Bar Linkage, Tianze Xu, David H. Myszka, Andrew P. Murray

Mechanical and Aerospace Engineering Faculty Publications

This paper presents a planar four-bar approximate motion synthesis technique that uses only pole locations. Synthesis for rigid-body guidance determines the linkage dimensions that guide a body in a desired manner. The desired motion is specified with task positions including a location and orientation angle. Approximation motion synthesis is necessary when an exact match to the task positions cannot be obtained. A linkage that achieves the task positions as closely as possible becomes desired. Structural error refers to the deviations between the task positions and the linkage's generated positions. A challenge in approximate motion synthesis is that structural error involves …

What’S Faith Got To Do With It? Young Earth Creationism And The Promise Of Certainty, William Vance Trollinger, Susan L. Trollinger

Intersections of Science and Faith

Contrary to what one might imagine, the proponents of Biblical creationism do not appeal to religious faith. Instead, they proclaim Genesis 1 as a historically and scientifically true description of creation by the only "eyewitness" (God), a description that they say is clearly substantiated by genuine, empirical science (as opposed to what they claim is the false, biased science of evolutionists). That is to say, young Earth creationists possess the certainty of truth.

Consequences Of Spatial Structure In Soil–Geomorphic Data On The Results Of Machine Learning Models, Daehyun Kim, Insang Song, Lorrayne Miralha, Daniel R. Hirmas, Ryan W. Mcewan, Tom G. Mueller, Pavel Samonil

Biology Faculty Publications

In this paper, we examined the degree to which inherent spatial structure in soil properties influences the outcomes of machine learning (ML) approaches to predicting soil spatial variability. We compared the performances of four ML algorithms (support vector machine, artificial neural network, random forest, and random forest for spatial data) against two non-ML algorithms (ordinary least squares regression and spatial filtering regression). None of the ML algorithms produced residuals that had lower mean values or were less autocorrelated over space compared with the non-ML approaches. We recommend the use of random forest when a soil variable of interest is weakly …
