A Decentralized Electronic Reporting Scheme with Privacy Protection Based on Proxy Signature and Blockchain

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022
The electronic reporting system can alleviate the problems in terms of efficiency, content confidentiality, and reporter privacy imposed in the traditional reporting system. Relying on anonymity, the privacy of reporters can be protected, but the authentication of reporters with fake names should also be maintained.

Influence of Misalignment on Beveloid Gear Tooth Contact and Dynamic Characteristics in Transfer Case Transmission of AWD Vehicle

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
Beveloid gears are usually employed to transfer motion of small shaft angle, but the assembly errors or misalignment can affect the gear tooth contact and dynamic performance. A dynamic model and tooth contact analysis model of the intersecting beveloid gear pair are established, the defects of the theoretical tooth surface in the meshing are analyzed,

Investigation of Load Sharing and Dynamic Load Characteristics of a Split Torque Transmission System with Double‐Helical Gear Modification

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021
A new dynamic model for a two‐input two‐path split torque transmission system which considers meshing error, time‐varying meshing stiffness, and meshing‐in impact is proposed. Time‐varying meshing stiffness and meshing‐in impact of each gear pair are accurately calculated based on tooth contact analysis and loaded tooth contact analysis.

Screen-Printed Graphite Electrodes as Low-Cost Devices for Oxygen Gas Detection in Room-Temperature Ionic Liquids

Sensors, 2017
Screen-printed graphite electrodes (SPGEs) have been used for the first time as platforms to detect oxygen gas in room-temperature ionic liquids (RTILs). Up until now, carbon-based SPEs have shown inferior behaviour compared to platinum and gold SPEs for

Analysis on Meshing Characteristics and Transmission Error of Elliptic Gears

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
As an important parameter to distinguish noncircular gear from cylindrical gear, eccentricity is very important for the meshing characteristics and transmission error of noncircular gear. In order to study the transmission characteristics of the elliptic gear, a pair of elliptic gear in the reversing device of a new type of drum pumping was taken as ...
