Numerical investigation into the effects of multiple bubbles in microchannel flow boiling
… present between the channel walls and the vapour bubbles. Many researchers have investigated a wide range of microchannel geometries, orientations and different working fluids and applied heat fluxes. The correlations developed between confined boiling, heat flux and pressure drop are for …

Modelling the flow behaviour of gas bubbles in a bubble column
… model framework that does predict the flow of multiple bubbles in the whole column. The non-linear Navier-Stokes (NVS) equations are used to model fluid flow around the bubble. This study focusses on the Reynolds number range where the linear Stokes equations can be used to accurately predict …

Time Series Analysis of Bitcoin
… are modelled and interpreted as speculative bubbles. The structure of the Bitcoin market is described to give context for the presence of multiple bubbles in the exchange rate. The bubbles may result from the speculative component in the on-line trading. The Bitcoin/USD exchange rates are …

Empirical studies of financial and labor economics
… tests. The empirical results suggest that multiple “bubbles” occurred in the Chinese stock market, although insufficient evidence is found to claim the same for the second-board market. The third chapter analyzes the trends of power couples’ concentration in large metropolitan areas of the …

Three essays on bubbles in agricultural futures markets
… of this dissertation is to test and understand bubbles in agricultural futures markets. Building on current bubble literature, the dissertation applies a recent-developed forward and backward recursive bubble testing procedure that is capable of date-stamping the exact origination and …

Applications and Advancements of Dynamic Isoelectric Focusing
… was a cellulase enzyme capable of degrading multiple cellulose materials over a wide range of environmental conditions. DIEF did isolate the protein in a pH span of 0.005 which is equivalent to 0.075% of the total pH range. Fractions were collected for sequencing analysis, but the fractions …

Microbubble streaming flows for non-invasive particle manipulation and liquid mixing
… devices. Under periodic acoustical driving, microbubbles with radius 20 -- 100µm absorbed or attached to a solid wall initiate steady streaming flows around the bubbles. These flows are driven by the Reynolds stresses in the boundary layer, a consequence of the nonlinearity of the Navier-Stokes …

Temporal Issues in Market Inefficiency in asset prices with an emphasis on commodities
… the literature on testing for explosive roots or bubbles. By modifying the Bhargava test statistic, we show in Chapter 2 that the Bhargava test can address earlier criticisms that had been cited against it; namely that it has low power when multiple bubbles are present in a particular series. …
