Polymer Electrolyte Membrane (PEM) fuel cells are regarded as an alternative power source for automotive and portable applications. Due to sensitivity of fuel cell to model parameters and nonlinear nature of the governing equations, proper control of the generated power is essential. In this...

An artificial neural network (ANN)-based dynamic model for an experimental variable speed direct expansion (DX) air conditioning (A/C) system has been developed, linking the indoor air temperature and humidity controlled by the DX A/C system with the variations of compressor and supply fan...

In a global environment context in which the urgent need to reduce pollutant emissions is of central relevance, it is becoming increasingly important the research for solutions, concerning the vehicular transport sector with low environmental impact. Fuel cell technology is expected to become a...

This paper presents the modeling and the experimental validation of air and water solar collectors used in humidification–dehumidification (HDH) solar desalination unit. The solar desalination process is currently operating under the climatological conditions of Sfax (34 N, 10 E), Tunisia. To...

Dynamic simulation of helium plants using Aspen Hysys®, V7.0 has been validated using cool-down temperature data from two existing helium plants under operation. Fluid properties of helium using 32-term MBWR EOS are found to be numerically unstable and Hepak® data has been fed as a table....

An investigation is made of the influence of fire-caused deforestation on precipitation-triggered, shallow landslide susceptibilities in southern California, using a scalable and extensible geo-fluid model (SEGMENT), that accounts for soil mechanics, root distribution, and relevant hydrologic...

An evolutionary computation approach for optimization of power factor and power output of wind turbines is discussed. Data-mining algorithms capture the relationships among the power output, power factor, and controllable and non-controllable variables of a 1.5MW wind turbine. An evolutionary...

We formulate a theoretical model in which we postulate that if a customers' behavior is perceived as not optimal, customers will adjust this behavior based on their current satisfaction and payment equity. Furthermore, customers will also include new experiences. In our empirical study we...

Although much academic and policy discussion has focused on replacing the income tax with a consumption-based tax, very few consumption-based direct tax reforms have been enacted. Much more common are approaches that reduce the level of capital-income taxation under an income tax, including the...
