Comparison of Numerical Simulation Models for Open Loop Flight Simulations in the Human Centrifuge [PDF]
, 2013 To achieve predefined Gz load profile in high G training in human centrifuge, it is necessary to determine angular velocity and acceleration of a planetary axis (centrifuge arm). Initial value problem that can not be solved in closed form was obtained.

, 2009 Life on Earth has developed at unit gravity, 9.81 m/s2, which was a major factor especially when vertebrates emerged from water onto land in the late Devonian, some 375 million years ago. But how would nature have evolved on a larger planet?

Adaptability of a jump movement pattern to a non-constant force field elicited via centrifugation.
PLoS ONE, 2020 Humans are accustomed to Earth's constant gravitational acceleration of 1g. Here we assessed if complex movements such as jumps can be adapted to different acceleration levels in a non-constant force field elicited through centrifugation.

Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]
, 1984 In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

Automation of Operation Control of the Human Centrifuge [PDF]
, 2022 Human centrifuge is a motion platform used to artificially achieve transient and sustained G-load intended for physiological pilot training under controlled conditions. This paper presents the successful modernization and upgrade of the control system of

Coherent Multimodal Sensory Information Allows Switching between Gravitoinertial Contexts
Frontiers in Physiology, 2017 Whether the central nervous system is capable to switch between contexts critically depends on experimental details. Motor control studies regularly adopt robotic devices to perturb the dynamics of a certain task.

Conditioning vs. Excitation Time for Estimating Impedance Parameters of the Human Arm [PDF]
, 2011 The human arm’s capability to alter its impedance has motivated multiple developments of robotic manipulators and control methods. It provides advantages during manipulation such as robustness against external disturbances and task adaptability ...

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]
, 2014 Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Human Arm Impedance and EMG in 3D [PDF]
, 2009 This paper shows the relationship between EMG signals and human arm stiffness, measured in 3-D space. Preliminary results demonstrate the viability of this approach, which can then be used to measure human arm impedance from EMG only.
