This paper will formulate integer programs to determine the optimal positions of wind turbines within a wind farm. The formulations were based on variations of the vertex packing problem. Three formulations are presented, which seek to maximize power generated in accordance with constraints based on the number of turbines, turbine proximity, and turbine interference. These were in the form of b...

Among motor vehicle crash head injuries, subdural hematomas (SDH) are both frequent and lifethreatening, especially for older occupants. Previous research on the mechanism of injury and on the increased vulnerability of older individuals to SDH has focused on the failure of bridging veins, which are one possible source of subdural bleeding. For all age groups, the injury mechanism and injury to...

There is an exceedingly small group of microorganisms that are considered pathogenic in humans relative to the microbial biota—with literally just a few bacterial and viral agents that have the potential to cause disease when transmitted in aerosol form. This group of pathogens has adapted to circumvent the rigors of airborne transport to enter the respiratory system and induce infection. The c...

This paper presents a comparison made between visualization skills in a group of students that take a course with graphics topics, and those that take a course with solid modeling. The graphics course (2D) is in the context of manual drafting and a drafting software, while the solid modeling course (3D) in based on the utilization of concepts and software for solid modeling. The objective pursu...

The integration of renewable generation and the electrification heating transportation are critical for sustainable energy transition toward net-zero greenhouse gas emissions. These changes require large-scale adoption distributed resources (DERs). Peer-to-peer (P2P) trading has gained attention as a new approach incentivizing uptake coordination DERs, with advantages computational scalability,...

The natural numbers may be our simplest, most useful, and best-studied abstract concepts, but their origins are debated. I consider this debate in the context of the proposal, by Gallistel and Gelman, that natural number system is a product of cognitive evolution and the proposal, by Carey, that it is a product of human cultural history. I offer a third proposal that builds on aspects of these ...
