The asset price bubble problem is not only the most concerned topic in financial circle, but also one of important research topics circle. In history, every time prices skyrocketed, bubbles were accumulated, and crash resulted a massive shrinking wealth, bankruptcy enterprises, economic recession. This paper based on theory investor behavioral bias finance theory, log-periodic power law (LPPL) ...

In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...

Since Bitcoin’s introduction in 2009, interest cryptocurrencies has soared. One manifestation of this been the explosion newly created coins and tokens. In paper, we analyze dynamics burgeoning industry. We consider both cryptocurrency The paper examines coin token creation, competition destruction order to conduct analysis, develop a methodology identify peaks prices trade volume, as well when...

Bubble columns are gas- liquid contactors that are widely used in chemical and bio- chemical industries. High mixing that result in high heat and mass transfer rates are amongst their advantages. Heat transfer in a bubble column having a bundle of heaters investigated and the variation of heat transfer coefficient with variation in heaters pitch to diameter ratios in a bundle of heaters reporte...

Periodically, some group of asset prices rises at a rapid pace that is matched neither by general price inflation nor seemingly by the relevant fundamental asset values. This situation rightfully causes great consternation at central banks, as it has dangerous implications for the stability of inflation and full employment and for financial stability. Some asset prices, such as those for housin...

People have long been fascinated by bubbles and foams dynamics, and since the pioneer work of Leonardo da Vinci in the early 16th century, this subject has generated a huge bibliography. However, only very recently, much interest was devoted to bubbles in champagne wines [1]. Small bubbles rising through the liquid, as well as a bubble ring (the so-called collar) at the periphery of a flute pou...

In this paper we test for the existence of asset price bubbles in Latin America in the 19802001 period, focusing mainly on stock prices. Based on unit root and cointegration tests we cannot reject the hypothesis of bubbles. We arrive at the same conclusion using Froot and Obstfeld’s intrinsic bubbles model. We identify periods of significant stock price overvaluation to examine empirical regula...

For the past decade, academics and practitioners have debated the existence of a housing bubble. Given the sharp declines in the housing market and the financial crisis, there is little doubt that a bubble occurred and then burst. Nevertheless, an important research question remains, what factors contributed to the creation of the bubble? This research addresses this issue by selecting well und...
