Abstract: Described is a computer-implemented method for modeling an equilibrium separation in a chemical separator. The method can include representing a feedstock of the chemical separator as a collection of molecules, each molecule having a mole fraction. A cluster analysis is performed on the feedstock based on a property of the collection of molecules to generate thermodynamic lumps. A mapping identity table is generated that identifies each molecule of the collection of molecules in the feedstock. A simulation of a chemical separation of the thermodynamic lumps is performed. The mole fraction of molecules in a resultant first phase and the mole fraction of molecules in a resultant second phase is determined.

Abstract: Embodiments of the present invention provide a method and device for transmitting signal. The method includes: obtaining a downlink beamforming matrix; and using a conjugate transposed matrix of the downlink beamforming matrix as an uplink beamforming matrix for processing uplink signal. In the embodiments of the present invention, the conjugate transposed matrix of the downlink beamforming matrix may be used as the uplink beamforming matrix for processing uplink signal, which can simplify design of the uplink beamforming matrix and thereby reduce complexity of the system.
