Development of a New Maximum Power Point Tracking Method for Power Conversion Efficiency Measurement of Metastable Perovskite Solar Cells

open access: yesElectrochemistry, 2020
A new algorithm for the maximum power point tracking (MPPT) method has been developed in order to determine the maximum power (Pmax) for slow-responding metastable PV devices such as perovskite solar cells (PSCs). It is well known that such devices often

Neutrino oscillation in a space-time with torsion [PDF]

open access: yes, 1999
Using the Einstein-Cartan-Dirac theory, we study the effect of torsion on neutrino oscillation. We see that torsion cannot induce neutrino oscillation, but affects it whenever oscillation exists for other reasons.

Oscillators and Oscillations in the Basal Ganglia [PDF]

open access: yesThe Neuroscientist, 2014
What is the meaning of an action potential? There must be different answers for neurons that fire spontaneously, even in the absence of synaptic input, and those driven to fire from a resting membrane potential. In spontaneously firing neurons, the occurrence of the next action potential is guaranteed; only variations in its timing can carry the ...

Hydrodynamics Study of Riser with Helical Strakes Oscillating in Flow

open access: yesShanghai Jiaotong Daxue xuebao, 2021
To reduce the vibration damage to the riser, hydrodynamic parameters of a smooth riser and a riser with triple symmetrically distributed helical strakes are evaluated in an experiment. The wave and current in natural environment are conceptualized to the

STUDYING THE DYNAMIC SYSTEM “TIRE-SUSPENSION-BODY” BY THE RESONANCE METHOD [PDF]

open access: yesTransport Problems, 2022
By comparing the results of a pilot study of the damping coefficient of a pneumatic tire carried out on a test bench, this study justifies the possibility of using the less time-consuming experimental resonance curve method instead of the dynamic loop

Finite oscillator models: the Hahn oscillator [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2011
A new model for the finite one-dimensional harmonic oscillator is proposed based upon the algebra u(2)_ . This algebra is a deformation of the Lie algebra u(2) extended by a parity operator, with deformation parameter . A class of irreducible unitary representations of u(2)_ is constructed.

Cerebellar Cortex 4–12 Hz Oscillations and Unit Phase Relation in the Awake Rat

open access: yesFrontiers in Systems Neuroscience, 2020
Oscillations in the granule cell layer (GCL) of the cerebellar cortex have been related to behavior and could facilitate communication with the cerebral cortex.

Bleeding Edge of Postmodernism: Metamodern Writing in the Novel by Thomas Pynchon

open access: yesInterlitteraria, 2019
Many different models of co ntemporary novel’s description arose from the search for methods and approaches of post-postmodern texts analysis. One of them is the concept of metamodernism, proposed by Timotheus Vermeulen and Robin van den Akker and based ...
