Filter bubble [PDF]

open access: yesInternet Policy Review, 2019
: Introduced by tech entrepreneur and activist Eli Pariser in 2011, the ‘filter bubble’ is a persistent concept which suggests that search engines and social media, together with their recommendation and personalisation algorithms, are centrally culpable

Bubble, Bubble, Where's the Housing Bubble? [PDF]

open access: yesBrookings Papers on Economic Activity, 2006
HOUSING PRICES HAVE risen by about 50 percent in the past five years, and more than 100 percent in some hot markets. Many knowledgeable observers believe that the United States is in the midst of a speculative bubble in residential real estate prices that rivals the dot-com bubble of the 1990s and that will have a similarly unhappy conclusion.

Rupture of an air bubble on the solid surfaces

open access: yesJournal of Fluid Science and Technology, 2018
We investigate behavior of bouncing and rupturing air bubbles on solid surfaces experimentally. We focus our attention to how the hydrophilicity of the solid surface alters the rupture process.

A New LB Model for Solid-liquid Conjugate Boiling Heat Transfer [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2023
To avoid the simulation error caused by the consistent solid-liquid energy transfer rate in the boiling heat transfer LB( lattice Boltzmann) model, different energy transfer rates of solid and liquid are successfully distinguished by tentatively ...

Performance Enhancement of Electrocatalytic Hydrogen Evolution through Coalescence-Induced Bubble Dynamics [PDF]

open access: yesJournal of the American Chemical Society
The evolution of electrogenerated gas bubbles during water electrolysis can significantly hamper the overall process efficiency. Promoting the departure of electrochemically generated bubbles during (water) electrolysis is therefore beneficial.

Periodic Porous 3D Electrodes Mitigate Gas Bubble Traffic during Alkaline Water Electrolysis at High Current Densities

open access: yesAdvanced Energy Materials, 2020
Alkaline water electrolysis at high current densities is plagued by gas bubble generation and trapping in stochastic porous electrodes (e.g., Ni foams), which causes a significant reduction in the number of electrolyte accessible catalyst active sites ...

Bubble CPAP: Not All Bubbling Is Good Bubbling [PDF]

open access: yesRespiratory Care, 2013
Since its introduction over 30 years ago,[1][1] bubble CPAP has become an important part of the management of neonatal respiratory distress syndrome. Similar to “ventilator-derived” or “machine-derived” CPAP devices, bubble CPAP devices apply pressure to the neonatal respiratory system ...

Behavior of Water Jet Accompanied with Air Suction

open access: yesJournal of Fluid Science and Technology, 2007
In order to atomize a liquid, the authors have investigated the behavior of air-water jets. In a series of experiments, we have discovered a strange phenomenon that the water jet accompanied with air suction from the free surface has made a periodic ...

Formation of Single Bubbles from a Submerged Orifice Using Pulsed Ultrasound Waves

open access: yesJournal of Fluid Science and Technology, 2008
A new experimental method is presented in which single small gas bubbles are generated in a liquid from a submerged orifice using pulsed ultrasound waves.
