Evaluation of Plasticity and Creep Parameters From Tensile Stress–Strain Data for a Range of Strain Rates

Advanced Engineering Materials, EarlyView.
This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

A Robust Deep Learning-Based Damage Identification Approach for SHM Considering Missing Data

Applied Sciences, 2023
Data-driven methods have shown promising results in structural health monitoring (SHM) applications. However, most of these approaches rely on the ideal dataset assumption and do not account for missing data, which can significantly impact their real ...

Two Techniques for the Efficient Numerical Calculation of the Green's Functions for Planar Shielded Circuits and Antennas [PDF]

, 2000
In this paper we present new contributions to the computation of the Green's functions arising in the analysis of mul- tilayered shielded printed circuits and antennas. First the quasi- static term of the spectral domain Green's functions is extracted

Open Source Tools for High Performance Quasi-Static-Time-Series Simulation Using Parallel Processing

2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017
Quasi-Static-Time-Series (QSTS) simulation is a valuable tool for evaluating the behavior of power systems through time. By performing daily, yearly and other time-based simulations, it is possible to characterize time-varying power conversion devices such as photovoltaic panels, storage, loads, and capacitors, among others within the power system ...

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Embedding quasi-static time series within a genetic algorithm for stochastic optimization: the case of reactive power compensation on distribution systems [PDF]

Journal of Computational Design and Engineering, 2020
Abstract This paper presents a methodology for the optimal placement and sizing of reactive power compensation devices in a distribution system (DS) with distributed generation. Quasi-static time series is embedded in an optimization method based on a genetic algorithm to adequately represent the uncertainty introduced by solar ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...
