Benefits of Waveform Relaxation Method and Output Space Mapping for the Optimization of Multirate Systems [PDF]

open access: yes, 2014
We present an optimization problem that requires to model a multirate system, composed of subsystems with different time constants. We use waveform relaxation method in order to simulate such a system.

Daily Beneficial Effects of Work-to-Family Facilitation on Employees' Recovery and General Health: Is More Work Engagement Always Better?

open access: yesFrontiers in Psychology, 2021
This study of 104 Chilean employees examines the process of WFF—recovery—general health on a daily basis. Drawing on the work–home resources (W-HR) model, we hypothesized that daily work-to-family facilitation and work engagement predict recovery ...
