Burning coal in power plants produces significant amounts of deposits like fouling and slagging on boiler surfaces which contributes to the overall poor performance of the power plants (by reducing electricity generation capacity, decreasing boiler efficiency and increasing overall maintenance cost). Recent research and development on boiler fouling and slagging problems, with the current preve...

In this Comment, we show that the expression for as proposed by R. Breban, R. Vardavas, and S. Blower, Phys. Rev. E 72, 046110 (2005) is incorrect and we reveal the underlying conceptual mistake.

Although use of carbon dioxide (CO2) blower has been regarded safe during off-pump coronary bypass surgery (OPCAB), we experienced a case of right coronary artery ischaemia induced by retrograde CO2 embolism originating from the opened obtuse marginalis artery during OPCAB. The spray pressure can exceed the diastolic pressure, especially during grafting at the lateral or posterior wall when hae...

This paper presents a condition diagnosis method for a blower system using the rough sets, and a fuzzy neural network to detect faults and distinguish fault types. In order to solve the ambiguous problem between the symptoms and the fault types, the diagnosis knowledge for the training of the neural network is acquired by using the rough sets. The fuzzy neural network realized by partially-line...

Using a mathematical model, Blower et al. (1) predicted the impact of antiretroviral therapy (ART) on future trends in the sexual spread of human immunodeficiency virus (HIV). The model employed Latin hypercube sampling to allow for the high degree of uncertainty in the estimation of many model parameters. The authors incorporated into their model the assumption that patients with drug-resistan...

This research aims to evaluate the influence of using air as a coolant on photovoltaic module's power output and electrical efficiency. Fossil energy, primary energy source today, has limited supply presents challenges in meeting future demands. In an effort address this issue, we conducted tests by implementing cooling system blower at bottom module. The were with varying flow rates, results i...

This article presents the results of the experimental runs of a prototype of R744 (CO2) refrigeration system operating in a both air conditioning and heat pump mode when heat rejection is done in supercritical region. The prototype system is sized for a compact car. Data presented are in the limited range of operation. Further optimization and extension of operating range is underway. Test faci...

The aerothermic process is a pilot scale heating and ventilation system. It is equipped with a heater grid and a centrifugal blower, fully connected through the Humusoft MF624 data acquisition system for real time control. The interaction between its main variables is considered as challenging for mono-variable controllers. An abrupt change in the ventilator speed might cause an undesirable dis...
