Fast S-Parameter TAN Model of n-Port Lumped Structures [PDF]

open access: yesIEEE Access, 2019
This paper deals with the fast S-parameter modeling of multi-port lumped structures. The developed model is based on unfamiliar formalism using the tensorial analysis of networks (TAN).

Modelling of SiC and GaN transistors based on pulsed S-parameter measurements

open access: yesPower Electronic Devices and Components
For the design of fast-switching inverters a precise model of power semiconductors is required. Based on pulsed S-parameter measurements in the frequency range of 2 MHz to 500 MHz a SiC MOSFET and a GaN HEMT have been characterized.

BPNN-Based Behavioral Modeling of the S-Parameter Variation Characteristics of PAs with Frequency at Different Temperatures

open access: yesMicromachines, 2022
To address the issue of frequency nonlinearity modeling of RF PAs, which is rarely seen in the literature, a BPNN is applied to model the frequency nonlinearity of RF PAs in this paper.

Holographic technicolor models and their S-parameter [PDF]

open access: yesJournal of High Energy Physics, 2009
We study the Peskin-Takeuchi S-parameter of holographic technicolor models. We present the recipe for computing the parameter in a generalized holographic setup. We then apply it to several holographic models that include: (a) the Sakai-Sugimoto model and (b) its non-compactified cousin, (c) a non-critical analog of (a) based on near extremal AdS_6 ...

Multipole and S-parameter based antenna model [PDF]

open access: yes2010 IEEE Antennas and Propagation Society International Symposium, 2010
Antenna characterization relating voltage sources to radiated fields is an important part of any electromagnetic measurement, with applications ranging from two-way communication systems to full-wave inverse scattering. Here, we derive a two-antenna model relating the multipole expansion of the fields radiated and received by antennas to S-parameter ...

New non‐homogeneous Poisson process software reliability model based on a 3‐parameter S‐shaped function

open access: yesIET Software, 2022
Software reliability modelling is the mathematical technique used to evaluate the reliability of a software system. The non‐homogeneous Poisson process is a prominent approach in this field.

Parameter-Free False Data Injection Attack Model on Power System’s Automatic Generation Control

open access: yesIEEE Access, 2023
Automatic generation control (AGC) plays a crucial role in frequency control and economic dispatch of electric power systems. However, AGC systems, relying heavily on frequency and tie-line power measurements, are vulnerable to cyber-attacks.

Effect of Sample Interval on the Parameter Identification Results of RC Equivalent Circuit Models of Li-ion Battery: An Investigation Based on HPPC Test Data

open access: yesBatteries, 2022
The validity of the equivalent circuit model (ECM), which is crucial for the development of lithium-ion batteries (LIBs) and state evaluation, is primarily dependent on the precision of the findings of parameter identification.

Determination of the kinematic parameters from SNe Ia and cosmic chronometers

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In this work, by assuming a spatially flat Universe, we have tested 8 kinematic parametrization models with H(z) data from Cosmic Chronometers and SNe Ia from Pantheon compilation.
