Abstract A three-component model for a belted radial tire, previously developed by the authors for free rolling without slip, is generalized to include longitudinal forces and deformations associated with driving and braking. Surface tractions at the tire-road interface are governed by a Coulomb friction law in which the coefficient of friction is assumed to be constant. After a brief review of the model, the mechanism of interfacial shear force generation is delineated and explored under traction with perfect adhesion. Addition of the friction law then leads to the inception of slide zones, which propagate through the footprint with increasing severity of maneuvers. Different behavior patterns under driving and braking are emphasized, with comparisons being given of sliding displacements, sliding velocities, and frictional work at the tire-road interface. As a further application of the model, the effect of friction coefficient and of test variables such as load, deflection, and inflation pressure on braking stiffness are computed and compared to analogous predictions on the braking spring rate.

Road Showmarked the acknowledgement of a gay sensibility in Sondheim’s work: not only do the homosexual couple, Addison Mizner and Hollis Bessemer, represent the show’s only functional relationship, the lovers sing its one duet, “The Best Thing that Ever Has Happened.” How do the queer instances that have always permeated Sondheim’s work resonate for gay audiences? While some critics attest that Sondheim must be read as a closeted writer, this is true only if you read his work superficially, focusing on questions regarding the relationships in his works: from Bobby’s chosen isolation inCompanythrough Sweeney’s villainous rampage inSweeney Todd(1979) to Fosca’s destructive behavior patterns inPassion(1994). The chapter reveals how, in dismantling the heteronormative structure of the traditional musical, Sondheim “queered” the form in a variety of ways.

The Impact

This study explored youth with Autism Spectrum Disorder (ASD) learning social competence in the context of innovative 3D virtual learning environment and the effects of gaming as a central element of the learning experience. The empirical study retrospectively compared the social interactions of 11 adolescents with ASD in game-and nongame-based 3D collaborative learning activities in the same social competence training curriculum. We employed a learning analytics approach - association rule mining to uncover the associative rules of verbal social interaction and nonverbal social interaction contributors from the large dataset of the coded social behaviors. By comparing the rules across the game and nongame activities, we found a significant difference in youth with ASD’s social performance. The results of the group comparison study indicated that the co-occurrence of verbal and nonverbal behaviors is much stronger in the game-based learning activities. The game activities also yielded more diverse social interaction behavior patterns. On the other hand, in the nongame activities, students’ social interaction behavior patterns are much more limited. Furthermore, the impact of game design principles on learning is then discussed in this paper.
