in this work, response surface methodology (rsm) and artificial neural network (ann) were used to predict the decolorization efficiency of reactive red 33 (rr 33) by o3/uv process in a bubble column reactor. the effects of four independent variables including time (20-60 min), superficial gas velocity (0.06-0.18 cm/s), initial concentration of dye (50-150 ppm) and ph (3-11) were investigated us...

Abstract Composite armors are widely used in the protection of human body and special vehicles due to their excellent ballistic performance. In this study, impact response SiC ceramics/Ultra-High Molecular Weight Polyethylene (UHMWPE) composite plate subjected fragment simulating projectiles (FSP) is investigated numerically. The influences head shape ceramic column position on failure modes, l...

The purification of wastewater is preferred using the adsorption by column due to process’s high efficiency. Column investigations are performed remove hazardous pollutants and demonstrate efficiency in treatment process. Cadmium zinc exist radioactive industrial wastes. Therefore, this work interested cadmium removal from utilising a fixed-bed column. Zirconia–silicate composite (ZrO2–SiO2) wa...

This paper proposes a macro-model for simulating the hysteretic behavior of composite-steel beams as part fully restrained beam-to-column connections in moment-resisting frames (MRFs). Comparisons with experimental data suggest that proposed model captures asymmetric response including cyclic deterioration strength and stiffness. Moreover, primary slab-column force transfer mechanisms predicts ...
