The paper tackles functioning aspects of elastomeric center-coupler draft gears.For the time being such draft gears are the only shock absorbers responsible for safe and secure transportation of hazardous materials and high-value car-goes.The predecessor research works dealing with force pattern intrinsic to impact and compression failed to present
The objective of this study is to investigate the influence of fly ash (FA), granulated blast furnace slag (GBFS), and a high-efficiency crack-resistant agent (HECRA) on the workability, mechanical properties, hydration heat (HH), adiabatic temperature rise (ATR), and volume stability of mass concrete (MC).Preliminary experiments determined that th
Flowers are generally short-lived, and they all face a multidimensional challenge because they have to attract mutualists, compel them to vector pollen with minimal investment in rewards, and repel floral enemies during this short time window.Their displays are under complex selection, either consistent or conflicting, to maximize reproductive fitn
This paper presents an automation strategy for multi-terminal HVDC (MT-HVDC) systems combining a dc optimal power flow (dc OPF) routine and a unified reference controller (URC).In the presented automatic framework, the dc OPF algorithm is implemented at the power dispatch center (PDC) of the MT-HVDC system to find optimal reference operation points
