This study tested hypotheses using two diet categorizations: total consumption percent and food material properties (FMPs). The first hypothesis that cortical bone area (CA) and section moduli (bone strength) are positively correlated with masticatory loading tests whether CA and moduli measures were greatest anteriorly and decreased posteriorly along the arch. The results found these measures adhered to this predicted pattern in the majority of taxa. The second hypothesis examines sutural complexity in the zygomaticotemporal suture as a function of dietary loading differences by calculating fractal dimensions as indices of complexity. No predictable pattern was found linking sutural complexity and diet in this primate sample, though hard object consumers possessed the most complex sutures. Lastly, cross-sectional geometric properties were measured to investigate whether bending and torsional resistance and cross-sectional shape are related to differences in masticatory loading. The highest measures of mechanical resistance tracked with areas of greatest strain in the majority of taxa. Cross-sectional shape differences do appear to reflect dietary differences. FMPs were not correlated with cross-sectional variables, however pairwise comparisons suggest taxa that ingest foods of greater stiffness experience relatively larger measures of bending and torsional resistance. The current study reveals that internal and external morphological factors vary across the arch and in conjunction with diet in primates. These findings underscore the importance of incorporating these mechanical differences in models of zygomatic arch mechanical behavior and primate craniofacial biomechanics.
Today, the vision of Commercial Supersonic Travel is often dreamed possible with innovation. Modern tech-business plans to reinvent commercial SuperSonic Transport (SST), while gaining reliable venture capital investment and proactive social backing. However, the concept’s global viability remains questionable, as regulation opposes its integrability. As a result, SST has become industrially forgotten. This research paper challenges the neglect of SST through routing optimizations derived from an industry’s collective research, while outlining decisive use-cases. Initially, this paper describes the difficulty in SST’s integration through its logistical tasks, demanding designs, and lacking efficiency. After that, the paper defines an optimization strategy, through software-analyzed flight paths, for overall supersonic operations. This strategy was proven to shorten established SST flights by 6%, while enabling the implementation of newfound SST paths. Here, optimization averaged 3.3% on density-derived routes and 5.4% on software-derived routes. More importantly, this paper demonstrated routing optimization enables MACH 1.6 aircraft to achieve MACH 2 flight times. Further, this paper attempts to justify SST through an analysis of its market, financials, and social perspectives. With that, the paper justifies an ideal SST customer earns 630$/hr, while such measurements vary amongst flight types. Finally, this paper conceptualizes that SST, with optimization, promises a noteworthy business, while developments in aircraft designs may revamp the aerospace industry completely.
