Modeling of residence time distribution : application to a three-phase inverse fluidized bed based on a Mellin transform [PDF]

, 2009
The study is focused on modeling of gas and liquid residence time distribution in an aerated liquid system of an inverse fluidized bed bioreactor. Two opposite strategies are currently available: the use of powerful complex computational fluid dynamics ...

Phase-Matching Quantum Key Distribution with Discrete Phase Randomization

Entropy, 2021
The twin-field quantum key distribution (TF-QKD) protocol and its variations have been proposed to overcome the linear Pirandola–Laurenza–Ottaviani–Banchi (PLOB) bound.

Imperfect Distributed Quantum Phase Estimation [PDF]

, 2020
In the near-term, the number of qubits in quantum computers will be limited to a few hundreds. Therefore, problems are often too large and complex to be run on quantum devices. By distributing quantum algorithms over different devices, larger problem instances can be run.

Uneven key pre-distribution scheme for multi-phase wireless sensor networks [PDF]

, 2013
In multi-phase Wireless Sensor Networks (WSNs), sensor nodes are redeployed periodically to replace nodes whose batteries are depleted. In order to keep the network resilient against node capture attacks across different deployment epochs, called ...

Deep learning for pore-scale two-phase flow: Modelling drainage in realistic porous media

Petroleum Exploration and Development
In order to predict phase distributions within complex pore structures during two-phase capillary-dominated drainage, we select subsamples from computerized tomography (CT) images of rocks and simulated porous media, and develop a pore morphology-based ...

Gas–Particle Partitioning and Temporal Dynamics of Pesticides in Urban Atmosphere Adjacent to Agriculture

Atmosphere
Air pollution caused by pesticide residues is an emerging concern in urban environments influenced by nearby agricultural activities. In this study, weekly air samples were collected between May 2018 and March 2020 in Strasbourg, France, to quantify 104 ...

Tunable Phase Distribution of Liquid Metamaterial

Advanced Photonics Research, 2022
A tunable liquid metamaterial (TLM) is proposed and demonstrated to possess phase tunability. TLM is composed of SiO2 nanopillars encapsulated with silicone oil.

Lattice Boltzmann Method simulation of wellbore gas–liquid​ phase transition

Energy Reports, 2022
Whenever the drilling wellbore is at the state of gas–liquid two-phase flow, gas slips and migrates along the drilling fluid. Due to the decreased wellbore temperature and pressure during gas migration, gas volume will gradually increase.

Wigner Quasiprobability of Coherent Phase States

Physics
The Wigner quasiprobability, along with some of its essentialproperties, is introduced and discussed in two versions, first covering real canonical variables such as W(q,p) and second a pair of complex conjugate coordinates such as W(α,α*).
