This paper deals with the design and the analysis of some nonlinear and adaptive control strategies capable to deal with the model uncertainties in an adaptive way for a complex and time varying bioprocess resulting from the association of a recycling bioreactor with an electrochemical reactor. The nonlinear controller design is based on the input-output linearizing technique. Computer simulati...

This paper reports the results of an experimental investigation on the effect of the EGR on the pollutants emission, especially on oxides of nitrogen, from the exhaust gases and performance of the spark ignition engine. Also along with experimental work, a mathematical model for the determination of the effect of EGR on the peak cycle temperature and for the prediction of its effect on the NOx ...

Recycling process is one of the most important processes in the trend of sustainable development,a logical reaction against the problems that results from industrial age. Building materials can play an important rolein the process of a building formation or destruction, in fact, materials forms the building nature. Thus, the role ofmaterial and the impact of its recycling in sustainable develop...

Kish Island is a popular tourist destination in Iran, and tourism plays an important role in its economy. The volume of waste produced in the island has increased given the construction of numerous industrial projects over the past decade, as well as an increase in the tourist population. This expansion signals a need to create new methods of waste disposal. Environmental Impact Assessment (EIA...

background. failure of orthodontic bracket bonds is a common occurrence during orthodontic treatment. different tech-niques have been suggested in the literature to remove resin residues from the bracket bases and enamel surfaces to prepare the surfaces again after debonding. this study attempted to compare multiple rebond shear strengths (sbs) of debonded brackets following preparation with sa...
