Fabrication of layered structure VS anchor in 3D graphene aerogels as a new cathode material for lithium

Frontiers in Energy 2019, Volume 13, Issue 3,   Pages 597-602 doi: doi:10.1007/s11708-018-0576-9

Abstract: VS4 has gained more and more attention for its high theoretical capacity (449 mAh/g with 3e− transfer) in lithium ion batteries (LIBs). Herein, a layered structure VS4 anchored in graphene aerogels is prepared and first reported as cathode material for LIBs. VS4@GAs composite exhibits an exceptional high initial reversible capacity (511 mAh/g), an excellent high-rate capability (191 mAh/g at the 5 C), and an excellent cyclic stability (239 mAh/g after 15 cycles).

Kinematic calibration of precise 6-DOF stewart platform-type positioning systems for radio telescope

Juan Carlos JáUREGUI, Eusebio E. HERNáNDEZ, Marco CECCARELLI, Carlos LóPEZ-CAJúN, Alejandro GARCíA

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 3,   Pages 252-260 doi: 10.1007/s11465-013-0249-7

Abstract:

The pose accuracy of a parallel robot is a function of the mobile platform posture. Thus, there is no a single value of the robot’s accuracy. In this paper, two novel methods for estimating the accuracy of parallel robots are presented. In the first method, the pose accuracy estimation is calculated by considering the propagation of each error, i.e., error variations are considered as a function of the actuator’s stroke. In the second method, it is considered that each actuator has a constant error at any stroke. Both methods can predict pose accuracy of precise robots at design stages, and/or can reduce calibration time of existing robots. An example of a six degree-of-freedom parallel manipulator is included to show the application of the proposed methods.
