3-D Move Mechanistic Analysis and Cost Effectiveness of Asphalt Rubber and Polymer Modified Asphalt Pavement Under Various Axle Loading Conditions

A variety of axle loading conditions can lead to different tensile strains in asphalt pavements. One way to increase resistance to these tensile strains is to add materials such as crumb rubber or polymers to the pavement mixture. Using three given asphalt pavement design mixtures, a 3D-Move mechanistic analysis was performed to determine the fatigue life of three given mixtures: unmodified reference, asphalt rubber, and polymer modified. These mixtures were tested under various axle loading conditions. This mechanistic analysis was then combined with a cost analysis which showed that despite the increase in cost, the asphalt rubber design mixture was the most cost-effective, with the polymer modified mixture finishing in second ahead of the unmodified reference mixture.

Logit Regression Model to Predict Driver Left Turn Destination Lane Choice Behavior at Urban Intersections

As autonomous vehicles become more prevalent during daily commutes, there will be an increased need to predict the driving behavior of humans behind the wheel. As this increase in prevalence will not be immediate, this human behavior prediction will be vital to minimize the number of traffic incidents between human-controlled and autonomous vehicles. One of the most unpredictable driving behaviors that can be observed is the destination lane choice of a driver turning left at an intersection. If this destination lane choice behavior can be predicted, then the introduction of autonomous vehicles can occur in a safer, more controlled manner. This research builds off of previous research by making use of two Next Generation Simulation (NGSIM) arterial street data sets in order to attempt to predict the turning behavior of human-controlled vehicles using real-world field data. This prediction can then be used in addition to the technology already in place in autonomous vehicles to decrease the risk of a collision at an intersection with a concurrently turning human-driven vehicle. Currently, there is no existing model that can accurately predict driver behavior due to the unpredictability of human-controlled vehicles. The resulting model will allow for a safer transition from human-controlled vehicles to autonomous vehicles. In addition to the safety benefits, this model could also be incorporated into popular microscopic traffic simulation tools, in order to improve the overall accuracy and efficiency of these tools

Paleogene Radiation of a Plant Pathogenic Mushroom

Background: The global movement and speciation of fungal plant pathogens is important, especially because of the economic losses they cause and the ease with which they are able to spread across large areas. Understanding the biogeography and origin of these plant pathogens can provide insights regarding their dispersal and current day distribution. We tested the hypothesis of a Gondwanan origin of the plant pathogenic mushroom genus Armillaria and the currently accepted premise that vicariance accounts for the extant distribution of the species. Methods: The phylogeny of a selection of Armillaria species was reconstructed based on Maximum Parsimony (MP), Maximum Likelihood (ML) and Bayesian Inference (BI). A timeline was then placed on the divergence of lineages using a Bayesian relaxed molecular clock approach. Results: Phylogenetic analyses of sequenced data for three combined nuclear regions provided strong support for three major geographically defined clades: Holarctic, South American-Australasian and African. Molecular dating placed the initial radiation of the genus at 54 million years ago within the Early Paleogene, postdating the tectonic break-up of Gondwana. Conclusions: The distribution of extant Armillaria species is the result of ancient long-distance dispersal rather than vicariance due to continental drift. As these finding are contrary to most prior vicariance hypotheses for fungi, our result

Literary studies and the academy

In 1885 the University of Oxford invited applications for the newly created Merton Professorship of English Language and Literature. The holder of the chair was, according to the statutes, to ‘lecture and give instruction on the broad history and criticism of English Language and Literature, and on the works of approved English authors’. This was not in itself a particularly innovatory move, as the study of English vernacular literature had played some part in higher education in Britain for over a century. Oxford University had put English as a subject into its pass degree in 1873, had been participating since 1878 in extension teaching, of which literary study formed a significant part, and had since 1881 been setting special examinations in the subject for its non-graduating women students. What was new was the fact that this ancient university appeared to be on the verge of granting the solid academic legitimacy of an established chair to an institutionally marginal and often contentious intellectual pursuit, acknowledging the study of literary texts in English to be a fit subject not just for women and the educationally disadvantaged but also for university men
