Development of a New Analytical Model for Hysteretic Behavior of Precast Segmental Self‐Centering Pier Columns

ABSTRACT This paper presents a comprehensive analytical model for predicting the hysteretic behavior of precast segmental self‐centering (PSC) pier columns with different energy dissipation (ED) device arrangements. Three typical PSC pier configurations are considered: no energy...

Chance-constrained model predictive control with online gaussian process learning reduces battery degradation in vehicle-to-grid service

Vehicle-to-grid (V2G) duty cycles are noisy and high-rate, and the capacity fade they cause is poorly described by the empirical, fixed-parameter degradation laws built into today’s model predictive control (MPC) battery managers. The controller sees a single number where it shou...

Starting performance comparison of R290 and R32 air conditioning systems under extreme cold conditions in Mohe China

Abstract The global phase-down of high-GWP refrigerants necessitates a transition to sustainable alternatives like R290 (GWP = 3) and R32 (GWP = 675). However, their dynamic startup reliability in extreme polar climates remains poorly understood. This study experimentally investi...
