The Proposal of a New Tool for Condition Assessment of Medium Voltage Power Cable Lines

Energies, 2021
A medium voltage (MV) cable network is a substantial component of the distribution network. Present management of this grid segment is mainly based on the failure rate analysis, i.e., a rise in the number and kind of faults on the actual line means that ...

Health inequalities and inequities by age: Stability for the Health Utilities Index and divergence for the Frailty Index

SSM - Population Health, 2018
Successful aging is an important policy goal in an aging society. A key indicator of successful aging of a population is whether health inequalities (differences) and inequities (unfair differences) in the population increase or decrease with age. This study investigates how health inequalities and inequities differ across age groups in the Canadian ...
