Abstract: Lift systems in high-rise buildings are often confronted with problems associated with optimum service delivery. The optimum performance of these systems in public high-rise buildings enhances the efficiency of vertical transportation systems. Time performance parameters like the Average Waiting Time (AWT), Transit Time (TRT), and Time to Destinati... Show More

Abstract: The greatest threat of the hazardous chemical release is posed by a cloud of contaminated air that spreads under the influence of wind near the soil surface. There is a problem of predicting the contaminated zone parameters in order to ensure safety. Normally, various methods are used to calculate the concentration of a hazardous impurity for this ...

Abstract: Background: The seasonal cycle of atmospheric carbon dioxide is usually ascribed to the seasonality of Northern Hemisphere vegetation, and the seasonal cycle of methane is usually ascribed to seasonal removal by the hydroxyl radical. Objective: We test an alternative, that the cycles of these greenhouse gases might be linked to sea ice dynamics. Me... Show More
