Evaluation of Power Systems Resilience to Extreme Weather Events: A Review of Methods and Assumptions

open access: yesIEEE Access, 2023
The requirement for a sustained supply of electricity intensifies during and in the aftermath of extreme events. In the past, events were considered extreme based on their extensive and devasting impacts and also because they were rare.

Entanglement of coherent states and decoherence [PDF]

open access: yes, 2000
A possibility to produce entangled superpositions of strong coherent states is discussed. A recent proposal by Howell and Yazell [Phys. Rev. A 62, 012102 (2000)] of a device which entangles two strong coherent coherent states is critically examined.

Exploratory Factor Analysis MSMEs Anti-Fragile

open access: yesInternational Journal of Science, Technology & Management, 2022
Developing a framework for MSMEs to become more fragile is the goal of this research. As it is known that the business world has fluctuated a lot and is facing turbulence, so we need an anti-fragile MSME framework concept. Using Exploratory Factor Analysis (EFA), this research is then analyzed to produce 5 (five) factors that build an anti-fragile MSME

Shear Fragility Analysis of Non-Classically Damped Three-Dimensional Structures Under Seismic Excitation

open access: yesBuildings
This study proposes a seismic performance evaluation method for structures using the base shear index to calculate the collapse probability. After non-proportional damping was applied to the three-dimensional bar system model, the structural dynamic ...
