Mechatronic modeling of a parallel kinematics multi-axial simulation table based on decoupling the actuators and manipulator dynamics
(Elsevier, 2016-11-07)
In this work a mechatronic model was developed for a parallel Multi-Axial Simulation Table (MAST) mechanism. The dynamics of the mechanism was obtained using the principle of energy equivalence and Boltzmann–Hamel equations. ...
Mechatronics of a ball screw drive using a N degrees of freedom dynamic model
(Springer, 2017-10)
High performance position control in machine tools can only be achieved modelling the dynamic behavior of the mechatronic system composed by the motor, transmission and control during the design stage. In this work, a ...
Quantum cosmology of the Big Rip: Within GR and in a modified theory of gravity
(MDPI, 2017-04-14)
Quantum gravity is the theory that is expected to successfully describe systems that are under strong gravitational effects while at the same time being of an extreme quantum nature. When this principle is applied to the ...
Regulation of Nociceptive Plasticity Threshold and DARPP-32 Phosphorylation in Spinal Dorsal Horn Neurons by Convergent Dopamine and Glutamate Inputs
(Public Library Science, 2016-09-09)
Dopamine can influence NMDA receptor function and regulate glutamate-triggered long-term changes in synaptic strength in several regions of the CNS. In spinal cord, regulation of the threshold of synaptic plasticity may ...
Association of Birth Order with Cardiovascular Disease Risk Factors in Young Adulthood: A Study of One Million Swedish Men
(Public Library of Science, 2013-05-16)
Background: Birth order has been suggested to be linked to several cardiovascular disease (CVD) risk factors, but the evidence is still inconsistent. We aim to determine the associations of birth order with body mass index ...
Experimental Validation of the Kinematic Design of 3PRS Compliant Parallel Mechanisms
(Elsevier, 2016-11)
In this paper, a procedure for the kinematic design of a 3-PRS compliant parallel manipulator of 3 degrees of freedom is proposed. First, under the assumption of small displacements, the solid body kinematics of the 3-PRS ...
Do alternating-color words facilitate reading aloud text in Chinese? Evidence with developing and adult readers
(Memory & Cognition, 2017)
Prior research has shown that colors induce perceptual grouping and, hence, colors can be used as word dividers during reading (Pinna & Deiana, 2014). This issue is particularly important for those writing systems that do ...
Cosmological Perturbations in Phantom Dark Energy Models
(MDPI, 2017-03-06)
The CDM paradigm, characterised by a constant equation of state w = -1 for dark energy, is the model that better fits observations. However, the same observations strongly support the possibility of a dark energy content ...
Formation of Surface and Quantum-Well States in Ultra Thin Pt Films on the Au(111) Surface
(MDPI, 2017-12-09)
The electronic structure of the Pt/Au(111) heterostructures with a number of Pt monolayers n ranging from one to three is studied in the density-functional-theory framework. The calculations demonstrate that the deposition ...
The Mimetic Born-Infeld Gravity: The Primordial Cosmos and Spherically Symmetric Solutions
(MDPI, 2017-11-27)
The Eddington-inspired-Born-Infeld (EiBI) model is reformulated within the mimetic approach. In the presence of a mimetic field, the model contains non-trivial vacuum solutions. We study a realistic primordial vacuum ...
