In this paper, we develop a multivariate regression model and neural network to predict the Reynolds number (Re) Nusselt in turbulent thermal convection. We compare their predictions with those of earlier models convection: Grossmann–Lohse [Phys. Rev. Lett. 86, 3316 (2001)], revised Fluids 33, 015113 (2021)], Pandey–Verma E 94, 053106 (2016)] models. observe that although all are quite close ea...

Three-dimensional block models are the most frequently used tool for estimating mineral resources and reserves within a deposit. In open pit mining, basis of mine design long term mining schedule is calculation ultimate limit. The limit with highest profit value. Over years, different algorithms have been developed that enable us to calculate final pit: floating or mobile cone, cone II its corr...

This work further elaborates on the steel plant MILP production scheduling method presented in Harjunkoski and Grossmann (2001). The proposed improvements include a more flexible model for the casting step, as well as combining orders from consecutive weeks to improve one of the main targets, which is increasing the number of heats per casting sequence. The paper presents a strategy to obtain o...

This rapporteur review covers selected results presented in the Parallel Session HEA2 (High Energy Astrophysics 2) of the 10th Marcel Grossmann Meeting on General Relativity, held in Rio de Janeiro, Brazil, July 2003. The subtopics are: ultra high energy cosmic ray anisotropies, the possible connection of these energetic particles with powerful gamma ray bursts, and new exciting scenarios with ...

We have shown how the quantization of two-dimensional quantum gravity with an action which contains only a positive cosmological constant and boundary cosmological constants leads to the emergence of a spacetime which can be described as a constant negative curvature spacetime with superimposed quantum fluctuations. Talk given by W. Westra at the Eleventh Marcel Grossmann Meeting on General Rel...

We address the problem of short-term scheduling of parallel batch reactors followed by continuously operating finishing trains to form work groups which is motivated by a real world problem at the Dow Chemical Company. The proposed MILP formulation is based on the recent planning model of ErdirikDogan and Grossmann (2007), and features additional constraints for handling complex arrangements ar...
