Peters, S.L.A. (author), Tabasi, A. (author), Kingma, I. (author), van Dijk, W. (author), van Dieën, J.H. (author)Mechanical loading of the low-back is an important risk factor for the development of low-back pain. Real-time estimation of the L5S1 joint moment (ML5S1) can give an insight to reduce mechanical loading. Model accuracy depends on sensor information, limiting the number of input variables to estimate ML5S1 increases practical feasibility, but...article 2023

(author)This paper introduces a AC stochastic optimal power flow (SOPF) for the flexibility management of electric vehicle (EV) charging pools in distribution networks under uncertainty. The AC SOPF considers discrete utility functions from charging pools as a compensation mechanism for eventual energy not served to their charging tasks. An application...article 2023

de Koning, M.C. (author), Vieiro Soares, C. (author), van Grol, M. (author), Bross, R.P.T. (author), Maurin, G. (author)Novichoks are a novel class of nerve agents (also referred to as the A-series) that were employed in several poisonings over the last few years. This calls for the development of novel countermeasures that can be applied in protective concepts (e.g., protective clothing) or in decontamination methods. The Zr metal−organic framework MOF-808 has...article 2022
