Experimentally derived models to detect onset of shunt resistance degradation in photovoltaic modules

open access: yesEnergy Reports, 2023
It has been shown that a reduction in the shunt resistance can lead to solar module degradation over time, resulting ultimately in module failure. This paper reports how the effects of reduced shunt resistance on the current–voltage (I-V) characteristics

Shunt resistance is associated with clinically important outcomes after the Norwood operationCentral MessagePerspective [PDF]

open access: yesJTCVS Open, 2022
Background: In single-ventricle physiology, focus on pulmonary vascular resistance neglects the resistance in the conduit supplying the pulmonary inflow. Methods: Conduit length and diameter, which can approximate conduit resistance, are available in the

Algorithms and mathematical model for determining shunt power of intelligent track section control sensor [PDF]

open access: yesE3S Web of Conferences, 2023
The normal operating state of jointless and butt track circuits depends on the state of change in the insulation resistance; respectively, the correct choice of the maximum and minimum limit resistance characteristics should be considered.

Non-contact measurements method of of solar cells shunt resistence in panel

open access: yesТехнічна інженерія, 2023
For the periodic control of photovoltaic solar panels during their operation, an important task is to obtain data on the internal condition of the solar cells’ plates, which may indicate the beginning of the degradation process due to the appearance and ...

Quantum Effects of Resistance-Shunted Josephson Junctions [PDF]

open access: yesJournal of the Physical Society of Japan, 2000
Thermodynamics and transport properties of resistance-shunted Josephson junctions are studied theoretically in the tight-binding limit E_C/E_J<<1, where E_C and E_J are a charging energy and a Josephson coupling energy respectively. Based on a phenomenological harmonic-oscillator model, weak coupling region K=R_Q/R<<1 is analytically ...

Vision Analysis of the Influence of Piezoelectric Energy Harvesting on Vibration Damping of a Cantilever Beam

open access: yesEnergies, 2021
A cantilever beam, manufactured from a steel-carrying substrate and two patches of Macro Fiber Composite of P2 type, was a subject of laboratory research. MFC patches were glued on both sides of the carrying substrate and were parallelly connected.

Hydrocephalus and shunts: a comparative flow-pressure study

open access: yesArchives of Pediatric Neurosurgery, 2021
Introduction: Differential Pressure Shunts (DPS) for hydrocephalus work through a pressure differential between the proximal and the distal inlet. Neurosurgeon’s reference is extra-low, low, medium, normal or high-pressure valves, symbolizing the shunt’s

Efficient Simulation of Resistively Shunted Josephson Junctions [PDF]

open access: yesPhysical Review Letters, 2005
We present a cluster algorithm for resistively shunted Josephson junctions or similar physical systems, which dramatically improves sampling efficiency, and apply it to the superconductor-to-metal transition in a single junction. Measuring the temperature dependence of the zero bias resistance, we confirm that the critical point does not depend on the ...

Adjusting the Single-Diode Model Parameters of a Photovoltaic Module with Irradiance and Temperature

open access: yesEnergies, 2020
This paper presents a concise discussion and an investigation of the most literature-reported methods for modifying the lumped-circuit parameters of the single-diode model (SDM) of a photovoltaic (PV) module, to suit the prevailing climatic conditions of
