Fleece Bodywarmers In the title compound, C23H19NO, the naphthalene ring system and the cyclopent-2-enone ring exhibit planar conformations with maximum deviations of 0.034 (1) and 0.02 (1) Å, respectively.The 1,4-dihydropyridine ring adopts an envelope conformation with the C atom bearing the p-tolyl ring Pow
This work addresses the development of Distributed Model Predictive Control (DMPC) approaches for the planning of maintenance operations of large-scale railway infrastructure formulated as a Mixed-Integer Linear Programming (MILP) problem.The proposed optimization problem is solved using two different decomposition schemes: Alternating Direction Me
The effects of metals such as cobalt (Co), cerium (Ce), magnesium (Mg), nickel (Ni) and titanium (Ti) added to diamond-like carbon (DLC) films on Notebook boundary lubrication properties were investigated using a ball-on disk tribometer.The boundary lubrication properties of metal-containing DLC films are improved compared with those of DLC films w
Purpose.The purpose of this work is to determine the energy losses in the shock absorber of the freight car whose wheel-set moves in the Power meters derailed state on the track panel depending on the axle load and structural parameters of spring suspension.Methodology.On the basis of spring suspension construction analysis and operating principle
The effects of climate change are now evident on a global level and indisputable even to the most skeptical.Melting ice, Glass Break Sensor rising sea levels, and changing climate zones are a daily occurrence and subject of debate in the media.Beyond the obvious effects of these phenomena on human lives, countless others arise and await being studi
