Research on the Modified Mathematical Prediction Model of Impeller Cover Side Cavity Liquid Pressure for Centrifugal Pumps [PDF]

Journal of Applied Fluid Mechanics, 2022
Accurate calculation of pressure distribution in the impeller cover side cavity is the key to predict the axial force of centrifugal pump. The existing calculation models almost does not involve the prediction of cavity pressure when the radial ...

Pressure drop rate threshold setting of block valves in hydrogen-blended natural gas pipelines

You-qi chuyun, 2021
The mixing of hydrogen will increase the leakage and explosion risk of natural gas pipelines. However, the pressure drop rate threshold of existing block valve in natural gas pipeline cannot meet the safety requirements of hydrogen-blended natural gas ...

Beyond Inferring Class Representatives: User-Level Privacy Leakage From Federated Learning [PDF]

IEEE Conference on Computer Communications, 2018
Federated learning, i.e., a mobile edge computing framework for deep learning, is a recent advance in privacy-preserving machine learning, where the model is trained in a decentralized manner by the clients, i.e., data curators, preventing the server ...

Semi‐supervised classification of fundus images combined with CNN and GCN

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Diabetic retinopathy (DR) is one of the most serious complications of diabetes, which is a kind of fundus lesion with specific changes. Early diagnosis of DR can effectively reduce the visual damage caused by DR. Due to the variety and different morphology of DR lesions, automatic classification of fundus images in mass screening can ...

Development of automatic shut-off valve for leakage of instrument pipe in gas transmission stations

You-qi chuyun, 2021
Gas leakage is the largest risk to the safe operation of natural gas transmission stations and valve chambers of long-distance gas pipelines, and it is of high probability for the leakage of instrument pipes.

Treatment planning with a 2.5 MV photon beam for radiation therapy

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The shallow depth of maximum dose and higher dose fall‐off gradient of a 2.5 MV beam along the central axis that is available for imaging on linear accelerators is investigated for treatment of shallow tumors and sparing the organs at risk (OARs) beyond it.

Leakage reduction in fast superconducting qubit gates via optimal control [PDF]

npj Quantum Information, 2020
Reaching high-speed, high-fidelity qubit operations requires precise control over the shape of the underlying pulses. For weakly anharmonic systems, such as superconducting transmon qubits, short gates lead to leakage to states outside of the ...

Rational Information Leakage [PDF]

SSRN Electronic Journal, 2010
Empirical evidence suggests that information leakage in capital markets is common. We present a trading model to study the incentives of an informed trader (e.g., a well-informed insider) to voluntarily leak information about an asset’s value to one or more independent traders.

Revisiting carbon leakage

Energy Economics, 2021
This paper estimates the carbon leakage rate across countries, arguably a key parameter in the international climate policy discussion including on border carbon adjustment, but which remains subject to significant uncertainty. We propose innovations along two lines. First, we exploit recently published data on sector-country-specific changes in energy

Anastomotic leakage after elective colorectal surgery: a prospective multicentre observational study on use of the Dutch leakage score, serum procalcitonin and serum C‐reactive protein for diagnosis

BJS Open, 2020
Background The purpose of this study was to test use of the Dutch leakage score (DLS), serum C‐reactive protein (CRP) and serum procalcitonin (PCT) in the diagnosis of anastomotic leakage (AL) after elective colorectal resection in a prospective ...
