Canine Pose Estimation: A Computing For Public Safety Solution, Cristina Ribeiro, Alexander Ferworn, Mieso Denko, James Tran

Publications and Scholarship

In this paper we discuss determining canine pose in the context of common poses observed in Urban Search and Rescue dogs through the use a sensor network made up of accelerometers. We discuss the use of the Canine Pose Estimation System in a disaster environment, and propose techniques for determining canine pose. In addition we discuss the challenges with this approach in such environments. This paper presents the experimental results obtained from the Heavy Urban Search and Rescue disaster simulation, where experiments were conducted using multiple canines, which show that angles can be derived from acceleration readings. Our experiments show …

In-Situ Measurements Of The Liquid-Phase Sintering Of Zinc Oxide, Mohammad Lutful Arefin

Polycrystalline ceramic semiconductor devices based on ZnO and several additive oxides show highly non-ohmic current-voltage behavior similar to the Zener diodes. The devices act as an insulator up to a certain electrical field called the breakdown field (EBR) but change into a highly conducting one just above it. Below and above the breakdown field they behave perfectly ohmic. This overall non-linear current-voltage characteristic together with the ability to withstand repeated high power pulses has made metal oxide varistors popular as "surge-arrestors" in electrical circuitry.

ZnO doped with Bi2O3 and Sb2O3 (ZBS), is the basic system for ceramic varistors. Phase formation …
