Experimental Study on Breakdown Characteristics of Transformer Oil Influenced by Bubbles
Energies, 2018 Bubbles will reduce the electric strength of transformer oil, and even result in the breakdown of the insulation. This paper has studied the breakdown voltages of transformer oil and oil-impregnated pressboard under alternating current (AC) and direct ...

Herd Behavior Experimental Testing and its Effect on Stock Pricing Using Agent-Based Simulation and STGP Algorithm [PDF]
فصلنامه بورس اوراق بهادار, 2022 The aim of this study is to investigate herding behavior bias and its impact on pricing mechanism using STGP algorithm and agent based simulation. For this purpose, 2000 virtual agents that categorized in two groups include a small subset of the total ...

Fate of bubble clusters rising in a quiescent liquid [PDF]
arXiv, 2023 We use experiments to study the evolution of bubble clusters in a swarm of freely rising, deformable bubbles. A new machine learning-aided algorithm allows us to identify and track bubbles in clusters and measure the cluster lifetimes. The results indicate that contamination in the carrier liquid can enhance the formation of bubble clusters and prolong

Radiation-Induced Helium Bubbles in Metals
Materials, 2019 Helium (He) bubbles are typical radiation defects in structural materials in nuclear reactors after high dose energetic particle irradiation. In the past decades, extensive studies have been conducted to explore the dynamic evolution of He bubbles under ...

Magnetic resonance imaging of oxygen microbubbles
Healthcare Technology Letters, 2019 Oxygen loaded microbubbles are being investigated as a means of reducing tumour hypoxia in order to improve response to cancer therapy. To optimise this approach, it is desirable to be able to measure changes in tissue oxygenation in real-time during ...

Complex rotation numbers: bubbles and their intersections [PDF]
Analysis & PDE 11 (2018) 1787-1801, 2017 The construction of complex rotation numbers, due to V.Arnold, gives rise to a fractal-like set "bubbles" related to a circle diffeomorphism. "Bubbles" is a complex analogue to Arnold tongues. This article contains a survey of the known properties of bubbles, as well as a variety of open questions.

The interaction of multiple bubbles in a Hele-Shaw channel [PDF]
, 2021 We study the dynamics of two air bubbles driven by the motion of a suspending viscous fluid in a Hele-Shaw channel with a small elevation along its centreline via physical experiment and numerical simulation of a depth-averaged model. For a single-bubble system we establish that, in general, bubble propagation speed monotonically increases with bubble ...

Should We Worry About Filter Bubbles?
, 2016 Some fear that personalised communication can lead to information cocoons or filter bubbles. For instance, a personalised news website could give more prominence to conservative or liberal media items, based on the (assumed) political interests of the ...

SSRN Electronic Journal, 2008 We use the notion of a housing bubble as an equilibrium in which some investors hold houses for resale purposes only and not with the expectation of receiving a dividend, either in the form of rent or utility. We show that an economy with looser collateral constraints is less prone to bubbles, which, in turn, have smaller size, but are more fragile in
