Industrial Robot Accuracy Degradation Monitoring and Quick Health Assessment

May 14, 2019
Author(s)
Guixiu Qiao, Brian A. Weiss
Robot accuracy degradation monitoring and assessment are critical activities in many industrial robot applications, especially when it comes to maintaining the high accuracy required operations, such as welding, material removal, robotic drilling, and

Rattling Behavior in a Simple Perovskite NaWO 3

May 1, 2019
Author(s)
Yuya Ikeuchi, Hiroshi Takatsu, Cedric Tassel, Craig Brown, Taito Murakami, Yuki Matsumoto, Yoshihiko Okamoto, Hiroshi Kageyama
A high-pressure reaction has allowed the preparation of stoichiometric tungsten bronze NaWO 3 (Im-3). Specific heat (C ;/T 3 vs T) exhibits a round peak at 30 K, indicating anharmonic phonon modes associated with low-energy rattling vibrations. Structural

Molecular Sieving of Ethylene from Ethane using a Rigid Metal-Organic Framework

November 26, 2018
Author(s)
Rui-Biao Lin, Libo Li, Hao-Long Zhou, Hui Wu, Chaohui He, Shun Li, Rajamani Krishna, Jinping Li, Wei Zhou, Banglin Chen
There are great challenges in developing efficient adsorbents to replace currently used and energy-intensive cryogenic distillation processes for olefin/paraffin separations, due to the similar physical properties of the two molecules. We report an

Model of Mobile Manipulator Performance Measurement using SysML

November 3, 2017
Author(s)
Roger V. Bostelman, Sebti Foufou, Tsai H. Hong, Mili Shah
Test methods for measuring safety and performance of mobile manipulators have yet to be developed. Therefore, potential mobile manipulator users cannot compare one system to another. Systems Modeling Language (SysML) is a general-purpose modeling language
