Including Lifetime Hydraulic Turbine Cost into Short-Term Hybrid Scheduling of Hydro and Solar
EnergiesIn traditional short-term hydropower scheduling problems, which usually determine the optimal power generation schedules within one week, the off-design zone of a hydraulic turbine is modeled as a forbidden zone due to the significantly increased risk of

Cyclic loading and fatigue of wood
, 2020 It is believed that energy can be saved by introducing fatigue-structural changes into wood using cyclic compression. Despite the common faith only one concept has been reported to save some 30% of energy [2] the reason for the saving still remaining unknown. Emphasis of the disquisition is on large i.e.
