Microgravity - Science and Technology, 2005
A short overview of boiling research in microgravity performed during the past two decades is subject of this presentation. The research was concentrated on pool boiling without applying any external forces. The objective of this research was to answer the questions: Is boiling an appropriate mechanism of heat transfer in space applications, and how do

SSRN Electronic Journal, 2014
AbstractWhile Eugene Fama has repeatedly expressed his discontent with the notion of an “irrational bubble,” he has never publicly expressed his opinion on “rational bubbles.” On empirical grounds Fama rejects bubbles by referring to the lack of reliable evidence that price declines are predictable.

International Economic Review, 1992
The definitions of "fundamental value" and "speculative bubbles" that are standard in macroeconomics and finance are given formal representations as the countably additive part and the purely finitely additive part (a measure and a pure charge, respectively) of the supporting price system, when the commodity space is LX'.

International comparison of bubbles and bubble indicators
AI & SOCIETY, 2013The purpose of this paper is to analyze the financial turmoil of the US subprime loan crisis of mid-Noughties and to compare it with the Japanese asset bubble of late 1980s. While examining the two crises, it compares the monetary policies of both countries, focusing on the excess liquidity and expansion of bank loans that were seen.

Stock Market Bubbles and Anti-Bubbles
SSRN Electronic Journal, 2018We develop a model of equity expected returns based on the idea that, on average, price equals replacement cost. Our main innovation is to allow for time-varying mean reversion speed in the dynamics of valuation. This time varying mean reversion speed captures complex nonlinear interactions, with the interaction between valuation and expected change in

Japan's Bubble, the USA's Bubble and China's Bubble
China & World Economy, 2011AbstractThis paper compares the three recent episodes of boom and bust cycles in asset prices: Japan in the late 1980s to the 1990s; the USA since the mid‐1990s; and China during the past decade. Although we have not yet seen a collapse of Chinese property prices, their increases so far are comparable to those in the other two episodes and a careful ...

Japan's Bubble, America's Bubble and China's Bubble [PDF]
, 2010 This paper compares the three recent episodes of boom and bust cycles in asset prices: Japan in the late 1980s to the 1990s; the U.S. since the mid 1990s; and China during the last decade. Although we have not yet seen a collapse of Chinese property prices, the increases so far are comparable to those in the other two episodes and seem to warrant a ...

Bubble Electrospinning and Bubble-Spun Nanofibers
Recent Patents on Nanotechnology, 2020Electrospinning is a highly efficient technology for fabrication of a wide variety of polymeric nanofibers. However, the development of traditional needle-based electrospinning has been hampered by its low productivity and need of tedious work dealing with needles cleaning, installation and uninstallation.

Credit bubbles and land bubbles [PDF]
, 2010 In modern macroeconomic models it is difficult to obtain explosive price bubbles on assets with positive net supply. This paper shows that it is possible to obtain explosive bubbles in certain situations when assets such as land are used as collateral and lenders are willing to lend freely against it.

Light Scattering by Bubbles in a Bubble Chamber
Applied Optics, 1968A discussion of the angular scattering expected from small bubbles in liquids of refractive indices 1.1 and 1.025 is given ogether with the inverse, i.e., of small spheres of the liquids in air. The similarities between the two scattering functions are compared with a view to the simulation of bubble chamber tracks using readily available materials ...
