Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, its diameter remains approximately constant. The center of mass of the bubble increases with t...

The era of Big Data is here now, which has brought both unprecedented opportunities and critical challenges. In this article, from a perspective of cognitive wireless networking, we start with a definition of Big Spectrum Data by analyzing its characteristics in terms of six V’s, i.e., volume, variety, velocity, veracity, viability, and value. We then present a high-level tutorial on research f...

Deep Anterior lamellar Keratoplasty (DALK) has become the corneal transplantation technique of choice for corneal diseases that spare the corneal endothelium. The major indications include keratoconus, stromal corneal dystrophies, corneal scars that spare the Descemet membrane (DM) and recalcitrant infectious keratitis. Unlike the old technique of penetrating/full thickness corneal transplantat...

The success of flotation operation depends upon the thriving interactions of chemical and physical variables. In this work, the effects of particle size, bubble size, and collector dosage on the bubble loading in a continuous flotation column were investigated. In other words, this work was mainly concerned with the evaluation of the true flotation response to the changes in the operating varia...

Information systems (IS) research has enfranchised established disciplines such as computer science, operational research, organizational behavior and management. Unfortunately, however, it has not been able to establish itself as a discipline in its own right, even though it is regarded as valid applied research and being a proponent to business process change. Nonetheless, its teaching and re...

An experimental study has been carried out to characterize bubble formation, growth, and detachment mechanisms in a stagnant liquid column. Both bubble frequency and bubble detachment size were measured in different gas flow rates, injector diameters and orientations, submergence height, and liquid properties. Experiments were performed for air injection flow rate ranges between 200 mlph and 12...
