Oil/water separation in a novel cyclone separator [PDF]

open access: yes, 2007
Conventional bulk oil-water separation is performed in large gravity separators that take up large areas and potentially contain large volumes of hazardous material.

A topological separation condition for fractal attractors [PDF]

open access: yes, 2009
We consider finite systems of contractive homeomorphisms of a complete metric space, which are non-redundant on every level. In general this separation condition is weaker than the strong open set condition and is not equivalent to the weak separation ...

Is functional separation BT-style the answer? [PDF]

open access: yes, 2008
This paper focuses on functional separation. After recounting the circumstances that culminated in the imposition of functional separation within the UK, the paper highlights the difficulties that have been encountered subsequent to the creation of ...

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

Flow Separation in Rocket Nozzles, a Simple Criteria [PDF]

open access: yes, 2005
Cold and hot flow tests were conducted to investigate the flow separation in rocket nozzles. The results are presented. A separation data base including a wide range of literature data is established to evaluate the influence of propellant combination ...

The Effect of C/Si Ratio and Fluorine Doping on the Gas Permeation Properties of Pendant-Type and Bridged-Type Organosilica Membranes

open access: yesMembranes, 2022
A series of pendant–type alkoxysilane structures with various carbon numbers (C1–C8) were used to fabricate sol–gel derived organosilica membranes to evaluate the effects of the C/Si ratio and fluorine doping. Initially, this investigation was focused on

A sensitive electrochemical analysis for cadmium and lead based on Nafion-Bismuth film in a water sample

open access: yesSensing and Bio-Sensing Research, 2021
This study presents a simple, low-cost, sensitive and environmentally friendly approach for the simultaneous electrochemical determination of lead and cadmium based on a commercial screen-printed gold electrode (SPGE) with Nafion and an in situ bismuth ...

Are Unobservables Separable? [PDF]

open access: yesSSRN Electronic Journal, 2017
It is common to assume in empirical research that observables and unobservables are additively separable, especially when the former are endogenous. This is because it is widely recognized that identification and estimation challenges arise when interactions between the two are allowed for.

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.

Hybrid Membrane-Distillation Separation Processes [PDF]

open access: yes, 2014
A novel synthesis approach is developed to evaluate and optimise various hybrid membrane-distillation schemes. The problem is formulated as an optimisation problem, where the objective is to minimise the total operating cost of the separation scheme ...
