A novel hybrid analytical/iterative method to extract the single-diode model's parameters using Lambert's W-function

open access: yesEnergy Conversion and Management: X, 2023
The evaluation of photovoltaic device performance is based on the I-V characteristic curve. Unfortunately, the data sheets provided by the manufacturers only include data at standard test conditions, which requires the construction of a model capable of ...

Factors Governing the Chemical Stability and NMR Parameters of Uracil Tautomers and Its 5-Halogen Derivatives

open access: yesMolecules, 2020
We report on the density functional theory (DFT) modelling of structural, energetic and NMR parameters of uracil and its derivatives (5-halogenouracil (5XU), X = F, Cl, Br and I) in vacuum and in water using the polarizable continuum model (PCM) and the ...

On physical web models

open access: yes2016 International Siberian Conference on Control and Communications (SIBCON), 2016
The Physical Web is a generic term describes interconnection of physical objects and web. The Physical Web lets present physical objects in a web. There are different ways to do that and we will discuss them in our paper. Usually, the web presentation for a physical object could be implemented with the help of mobile devices.

Robust Predictive Control Design of Wind Power under Nonlinear Constraints [PDF]

open access: yesEPJ Web of Conferences
This paper aims to develop a novel control architecture to enhance the performance of DFIG-based wind turbines. The proposed approach integrates an adaptive robust predictive control law to ensure stable power output despite stochastic wind variations ...

Models in physics [PDF]

open access: yes, 2018
In its most common use, the term ‘model’ refers to a simplified and stylised version of the so-called target system, the part or aspect of the world that we are interested in. For instance, in order to determine the orbit of a planet moving around the sun we model the planet and the sun as perfect homogenous spheres that gravitationally interact with ...

Predictor-based resilient control of continuous-time cyber–physical systems under denial-of-service attacks [PDF]

open access: yesEPJ Web of Conferences
This paper studies predictor-based resilient control for continuous-time linear cyber-physical systems under denial-of-service attacks. Deterministic DoS frequency and duration constraints are used to guarantee bounded intervals between successful ...
