Separability and Aggregation [PDF]

open access: yesEconomica, 1990
This paper examines the conditions for homothetic separability of a technology that is an aggregate of technologies of individual firms or industries. Given that the primitive (industry or firm) technologies exhibit homothetic separability, the authors establish necessary and sufficient conditions for the aggregate (sectoral) technology to also exhibit

Rethinking The Separation Layers In Speech Separation Networks [PDF]

open access: yesICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
Modules in all existing speech separation networks can be categorized into single-input-multi-output (SIMO) modules and single-input-single-output (SISO) modules. SIMO modules generate more outputs than input, and SISO modules keep the numbers of input and output the same.

A Review of One‐Dimensional Nanomaterials as Electrode Materials for Oxygen Reduction Reaction Electrocatalysis

open access: yesChemElectroChem, 2022
In fuel cells, the generally low oxygen reduction reactions (ORR) rate at the cathode is a major factor limiting the overall performance of fuel cell, so the development of high‐performance, stable and inexpensive ORR electrocatalysts is a major ...

Behavior of ions from medium-density plasma in electric field created by plate–grid–plate geometry

open access: yesAIP Advances, 2022
The behavior of the ions from a medium-density plasma in an electric field created by the plate–grid–plate geometry was simulated with a two-dimensional one-fluid model in which electrons are assumed to be in thermal equilibrium, and the accuracy of the ...

Metal confined in metal‐organic framework‐based mixed matrix membranes for efficient butadiene recognition separation

open access: yesAggregate, 2023
The efficient separation of butadiene (1,3‐C4H6) from C4 hydrocarbons is a critical step in petrochemical processes. However, the traditional cryogenic distillation suffers from energy‐intensity and serious environmental stress, necessitating the ...
