Wireless communication involving unmanned aerial vehicles (UAVs) is expected to play an important role in future wireless networks. However, different from conventional terrestrial systems, UAVs typically have rather limited onboard energy on one hand, and require additional flying consumption the other hand. This renders energy-efficient UAV with smart expenditure of paramount importance. In t...

in this study, liquid-liquid extraction process in a kuhni extraction column was modeled and simulated. a non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. the model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. the population balance model was used ...

in this paper the critical strain energy release rate for t300/913 carbon-epoxy laminated composites has been studied using ansys finite element software based on virtual crack closure technique ( vcct ). compact tension ( ct ) specimen has been used for numerical analyses and the geometrical dimensions have been extracted from the existing references. the results obtained from the finite eleme...

the recovery and removal of the most organic acids in liquid solutions is usually treated with fixed-bed adsorption processes. among many adsorbents, granular activated carbon (gac) is used to remove organic pollutants such as benzoic acid (ba) from wastewaters conventionally. in this research, adsorption isotherm curves of ba onto gac at varying temperatures 25-60 °c are developed and the amou...

effect of water gas shift reaction (co+h2o=co2+h2) on wustite reduction has been investigated by a transient, non-isothermal mathematical model based on grain model. in this model, wustite porous pellet is reduced using syngas, namely a mixture of hydrogen, carbon monoxide, carbon dioxide and water vapor. for this purpose, governing equations containing continuity equation of species and energy...

OBJECTIVE To investigate the mode of action of methotrexate (MTX) in different types of models for rheumatoid arthritis (RA) and multiple sclerosis (MS). METHODS Models for RA and MS were selected known to have different pathogenesis--that is, fibroblast induced arthritis in SCID mice, collagen induced arthritis (CIA), anticollagen II antibody induced arthritis (CAIA), and experimental autoim...

This is a revision of a book which has already become established as an authoritative text on the design of experiments. It gives both an exposition of the practical aspects of this subject, as interpreted in modern statistics, and also a brief account of the mathematical model underlying each design. It is assumed that the reader has previously had an introduction to statistical methods, parti...
