Vibration and buckling of open TWBs with local weakening [PDF]
, 2017 Free vibration and Ljapounov stability of compressed open thin-walled beams with a cross-section reduction are studied by a in-house finite differences numerical code, based on a refined direct beam model and allowing for investigating elastic stability ...

Reengineering and selective recovery of iron-bearing silicate minerals
工程科学学报, 2015 The recovery of iron-bearing silicate minerals is a key on the re-separation middlings of Anshan type lean magnetite,but this recovery process should be conducted selectively. The iron grade of stage 1 tailing is only 3.92%,so there is no need to recover

Energy Consumption and CO2 Emissions in Ironmaking and Development of a Novel Flash Technology
Metals, 2019 The issues of energy consumption and CO2 emissions of major ironmaking processes, including several new technologies, are assessed. These two issues are interconnected in that the production and use of fuels to generate energy add to the total amount of ...

Dimensional reduction for directed branched polymers [PDF]
Journal of Physics A: Mathematical and General, 2004 Dimensional reduction occurs when the critical behavior of one system can be related to that of another system in a lower dimension. We show that this occurs for directed branched polymers (DBP) by giving an exact relationship between DBP models in D+1 dimensions and repulsive gases at negative activity in D dimensions.

Hydrogen Ironmaking: How It Works
Metals, 2020 A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the ...

Prediction of Solid Conversion Process in Direct Reduction Iron Oxide Using Machine Learning
Energies, 2022 The direct reduction process has been developed and investigated in recent years due to less pollution than other methods. In this work, the first direct reduction iron oxide (DRI) modeling has been developed using artificial neural networks (ANN ...

Software Directed Issue Queue Power Reduction [PDF]
11th International Symposium on High-Performance Computer Architecture, 2005 The issue logic of a superscalar processor dissipates a large amount of static and dynamic power. Furthermore, its power density makes it a hot-spot requiring expensive cooling systems and additional packaging. In this paper we present a novel software assisted approach to power reduction where the processor dynamically resizes the issue queue based on

Quantum lattice gauge fields and groupoid C*-algebras [PDF]
, 2017 We present an operator-algebraic approach to the quantization and reduction of lattice field theories. Our approach uses groupoid C*-algebras to describe the observables and exploits Rieffel induction to implement the quantum gauge symmetries.

REM: International Engineering Journal, 2021 The Direct Reduction (DR) process has been growing worldwide, and there are strong context suggestions that it will grow even more. One of these factors is the environmental pressure that occurs worldwide, and there are already projects to migrate Blast ...
