Numerical Investigations on Temperature Distribution and Evolution of Cavitation Bubble Collapsed Near Solid Wall

open access: yesFrontiers in Energy Research, 2022
The internal temperature distribution and evolution in cavitation bubble can be investigated numerically by a thermal lattice Boltzmann method. The simulation results are consistent with the calculational results of the Rayleigh-Plesset equation and the ...

Quantum dense key distribution [PDF]

open access: yesPhysical Review A, 2004
This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to generate shared secret keys four times more efficiently than BB84 one. We hereinafter prove the security of this scheme against individual eavesdropping attacks, and we present ...

Fully Passive Quantum Key Distribution

open access: yesPhysical Review Letters, 2023
Passive implementations of quantum key distribution (QKD) sources are highly desirable as they eliminate side-channels that active modulators might introduce. Up till now, passive decoy-state and passive encoding BB84 schemes have both been proposed.

High-Frequency Current Ripple Sample Anti-Aliasing Strategy of Digitally Controlled Converter Based on Notch Filter

open access: yesIEEE Access, 2023
The digital controller of the grid-connected converter achieves closed-loop control by sampling key voltage and current signals. High-frequency switching of power electronic switches introduces high-frequency ripples into the signals, which may cause ...

Fundamental limits on key rates in device-independent quantum key distribution [PDF]

open access: yes, 2020
In this paper, we introduce intrinsic non-locality as a quantifier for Bell non-locality, and we prove that it satisfies certain desirable properties such as faithfulness, convexity, and monotonicity under local operations and shared randomness.

A two-stage optimization method for unmanned aerial vehicle inspection of an oil and gas pipeline network

open access: yesPetroleum Science, 2019
Oil and gas pipeline networks are a key link in the coordinated development of oil and gas both upstream and downstream. To improve the reliability and safety of the oil and gas pipeline network, inspections are implemented to minimize the risk of ...

An MILP approach for detailed scheduling of oil depots along a multi-product pipeline

open access: yesPetroleum Science, 2017
Oil depots along products pipelines are important components of the pipeline transportation system and down-stream markets. The operating costs of oil depots account for a large proportion of the total system’s operating costs.

Chip-based quantum key distribution [PDF]

open access: yesNature Communications, 2017
AbstractImprovement in secure transmission of information is an urgent need for governments, corporations and individuals. Quantum key distribution (QKD) promises security based on the laws of physics and has rapidly grown from proof-of-concept to robust demonstrations and deployment of commercial systems.

Dynamic Equivalent Modeling of a Grid-Tied Microgrid Based on Characteristic Model and Measurement Data

open access: yesEnergies, 2017
Microgrids can significantly improve the utilization of distributed generation (DG) and the reliability of the power supply. However, in the grid-tied operational mode, the interaction between the microgrid and the distribution network cannot be ignored.
