Secondary transfer effects of intergroup contact : Alternative accounts and underlying processes [PDF]

open access: yes, 2010
Although intergroup contact is one of the most prominent interventions to reduce prejudice, the generalization of contact effects is still a contentious issue.

Elastic-contact-based tool-path planning for free-form surface in belt grinding

open access: yesAdvances in Mechanical Engineering, 2019
As for the fact that the majority of current researches take the technology of tool-path planning for free-form surface only as a geometrical problem, which is not suitable for belt grinding because of the elastic deformation of the grinding belt that ...

Pain responses in athletes: the role of contact sports [PDF]

open access: yes, 2018
High contact athletes differ from low or non-contact athletes in their responses to pain. The mechanisms for this have not been widely investigated and most sports-related pain research has not differentiated between the three sources of pain: contact ...

Analysis of arbitrary tooth profiles of cylindrical gears using normal polar coordinates (Application to the generation of a gear tooth profile by a given tooth profile of rack cutter and its interference problem)

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing
Various coordinate systems have been used in tooth profile analysis for cylindrical gears. An effective approach to tooth profile expression using normal polar coordinates is proposed.

Algorithms for optimal min hop and foremost paths in interval temporal graphs

open access: yesApplied Network Science, 2022
Path problems are fundamental to the study of graphs. Temporal graphs are graphs in which the edges connecting the vertices change with time. Min hop paths problem in a temporal graph is the problem of finding time respecting paths from source vertex to ...

An efficient dynamics model of spur gear drive with curved path of contact in mixed elastohydrodynamic lubrication

open access: yesMechanics & Industry, 2022
Design of new tooth shapes have been the focus of gear researchers aimed at overcoming the defects of involute gears. For the spur gear drive with curved path of contact, normal contact loads between engaged teeth vary in direction and magnitude, which ...

The Binary Contact Path Process

open access: yesThe Annals of Probability, 1983
We study some $\{0, 1, \cdots\}^{z^d}$ valued Markov interactions $\eta_t$ called contact path processes. These are similar to branching random walks, in that the normalized size process starting from a singleton is a martingale which converges to a limit $M_\infty$.
