Positioning Accuracy Analysis of the Parallel Mechanism Near Singular Positions
This paper presents a method of numerical modelling of parallel mechanisms with clearances in their kinematic pairs taken into account. The pairs with clearances are modelled as shape connections based on constraints in the form of contact interactions ...

Multibody Dynamics Model of a Human Hand for Haptics Interaction [PDF]
In this paper we propose a strategy for modelling a human hand for Haptics interaction. The strategy consists in a parallel computing architecture that calculates the dynamics of a hand; this is accomplished by computing the dynamics of each finger in a ...

Formalization of Phase Ordering
Phasers pose an interesting synchronization mechanism that generalizes many collective synchronization patterns seen in parallel programming languages, including barriers, clocks, and point-to-point synchronization using latches or semaphores.

We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The human wrist affects the ability to efficiently perform many manipulation tasks. Despite this, most upper-limb prostheses are focused on the hand’s mobility, which makes users compensate for the lost wrist mobility with complex manipulation strategies

Stochastic Particle Acceleration in Parallel Relativistic Shocks
We present results of test-particle simulations on both the first- and the second-order Fermi acceleration for relativistic parallel shock waves.

Parallel moving mechanical systems
Moving mechanical systems parallel structures are solid, fast, and accurate. Between parallel systems it is to be noticed Stewart platforms, as the oldest systems, fast, solid and precise. The work outlines a few main elements of Stewart platforms.

We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Kinematics and Workspace Analysis of 4-SPRR-SPR 5-DOF Parallel Mechanism
Taking a 2T3R 5-DOF 4-SPRR-SPR parallel mechanism with rotating axis as the moving platform as the research object, the degree of freedom of the 4-SPRR-SPR parallel mechanism is analyzed by the screw theory, the inverse kinematics equation of the ...
