Stability Evaluation and Mechanism of Asphalts Modified With Various Rubber Powder Contents

open access: yesFrontiers in Materials, 2021
Ground tires are one of the main sources of urban solid waste. Rubber powder-modified asphalt provides an effective method to solve the problem, and it presents good high- and low-temperature performance in sustainable pavement construction. However, the

Transparency in Port-Hamiltonian-Based Telemanipulation [PDF]

open access: yes, 2007
After stability, transparency is the major issue in the design of a telemanipulation system. In this paper, we exploit the behavioral approach in order to provide an index for the evaluation of transparency in port-Hamiltonian-based teleoperators ...

Accurate simulations of the interplay between process and statistical variability for nanoscale FinFET-based SRAM cell stability [PDF]

open access: yes, 2014
In this paper we illustrate how by using advanced atomistic TCAD tools the interplay between long-range process variation and short-range statistical variability in FinFETs can be accurately modelled and simulated for the purposes of Design-Technology Co-

Cluster and group synchronization in delay-coupled networks

open access: yes, 2012
We investigate the stability of synchronized states in delay-coupled networks where synchronization takes place in groups of different local dynamics or in cluster states in networks with identical local dynamics.

Evaluation of Simulations for Short-Term Voltage Stability Assessment with Respect to Model Uncertainties

open access: yesEng
In order to evaluate the short-term voltage stability of an electrical power grid, it is necessary to employ not only systematic and well-targeted fault simulations, but also an evaluation method that assesses the criticality of the individual scenarios.
