Design and analysis of driving mechanism of flapping-wing aircraft based on space crank-swing rod mechanism

open access: yes上海师范大学学报. 自然科学版, 2022
In order to improve the flight performance of the flapping-wing aircraft,a novel multi-degree of freedom flapping-wing mechanism based on the space pendulum mechanism was designed by referring to the flight motion characteristics of living things.

Star Clusters in M31: Old Clusters with Bar Kinematics [PDF]

open access: yes, 2010
We analyze our accurate kinematical data for the old clusters in the inner regions of M31. These velocities are based on high S/N Hectospec data (Caldwell et al 2010).

The influence of barefoot and barefoot inspired footwear on the kinetics and kinematics of running in comparison to conventional running shoes. [PDF]

open access: yes, 2012
Barefoot running has experienced a resurgence in footwear biomechanics literature, based on the supposition that it serves to reduce the occurrence of overuse injuries in comparison to conventional shoe models.

The Two-fold Role of Observables in Classical and Quantum Kinematics [PDF]

open access: yes, 2017
Observables have a dual nature in both classical and quantum kinematics: they are at the same time \emph{quantities}, allowing to separate states by means of their numerical values, and \emph{generators of transformations}, establishing relations between

Positive Torque Modulation Method and Key Technology of Conventional Beam Pumping Unit

open access: yesEnergies, 2022
The large fluctuation of net torque and the existence of negative torque on the crank output shaft of the beam pumping unit are the decisive factors leading to its low efficiency and high energy consumption.

Mapping the inner regions of the polar disk galaxy NGC4650A with MUSE [PDF]

open access: yes, 2015
[abridged] The polar disk galaxy NGC4650A was observed during the commissioning of the MUSE at the ESO VLT to obtain the first 2D map of the velocity and velocity dispersion for both stars and gas.

Application of direct and inverse kinematics and dynamics in motion planning of manipulator links

open access: yesInternational Journal of Applied Mechanics and Engineering, 2023
For the synthesis of manipulators and robots, an accurate analysis of the movements of the individual links is essential. This thesis deals with motion planning of the effector of a multi-linked manipulator.
