Orion Routing Protocol for Delay-Tolerant Networks [PDF]

, 2011
In this paper, we address the problem of efficient routing in delay tolerant network. We propose a new routing protocol dubbed as ORION. In ORION, only a single copy of a data packet is kept in the network and transmitted, contact by contact, towards the

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)

Journal 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.

Analysis of Mastication Path with Various Occlusal Contact.

Nihon Hotetsu Shika Gakkai Zasshi, 1992
This study is for examining the difference between a normal occlusion and experimental premature contacts (30 and 60μm) existing the lower first molar in the masticatory path using a covariance analysis.1. No significant difference was found in the opening phase, and a significant difference was found in the closing phase between the natural and exist ...

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

Applied 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

Mechanics & 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 ...

Dephasing due to Which Path Detector

, 1997
We study dephasing of electrons induced by a which path detector and thus verify Bohr's complementarity principle for fermions. We utilize a double path interferometer with two slits, with one slit being replaced by a coherent quantum dot (QD).
