Energy variations and periodic solutions in a switched inverted pendulum model of human running gaits

Making photocatalysts screenable – a milliscale multi-batch screening photoreactor as extension for the modular photoreactor

“…All information of the proposed setup can be found in the git repository of the modular photoreactor, characterization and catalytic data is deposited in Zenodo. 56,57,89…”

“…The light sources were controlled with the controller module presented together with the modular photoreactor in combination with an RND Ka3005p lab power supply. 27,56,57 A commercially available roller shaker (IKA roller shaker 10 digital) was used as basis for irradiating up to 63 4 mL GC-vials that served as photoreactors at the same time. The solutions in the milli-scale photoreactors were efficiently mixed by applying rotation of the GC-vials along with an ellipsoidal movement of the shaker with up to 80 rpm and were used to study photoreactions with liquid and gaseous products under inert atmosphere through straight forward reaction monitoring by gas chromatography and UV/vis spectroscopy.…”

Revealing the inherent running mechanism of quadruped mammals based on a novel bionic stiffness model

“…The step-to-fall analysis (SFA) method was first presented by Seyfarth et al in the literature [ 30 ]: this method is an effective numerical simulation method that aims at the case of a complex analytical expression of dynamics. Wróblewska et al presented an analytical approximation of a reduced mapping which can be able to explicitly control the error of the approximation [ 31 , 32 ]. For the SFA method of classic SLIP model, the parameter set of can determine the dynamics system.…”

A New Method Investigation for Robotic Inverted Pendulum Movement and Control

“…The symbols present in the given equation are explicitly defined as follows: The symbols M(q), 𝐶(𝑞. 𝑞̇), A, P, u, and λ respectively represent the inertia matrix, Coriolis and centrifugal force vector, constraint matrix, input transform matrix, input torque vector, and Lagrangian multiplier [9][10][11][12][13][14][15][16].…”

“…Since the gyro sensor works well at high frequencies, it may be used in conjunction with the tilt sensor, which works well at low frequencies. The complementary filter is the result [15,16].…”
