many efforts have been made to model the the hot deformation (dynamic recrystallization) flow curves of different materials. phenomenological constitutive models, physical-based constitutive models and artificial neural network (ann) models are the main methods used for this purpose. however, there is no report on the modeling of warm deformation (dynamic spheroidization) flow curves of any kin...

cash flow forecasting is an indispensable tool for construction companies, and is essential for the survivalof any contractor at all stages of the work. the time available for a detailed pre-tender cash flow forecast is oftenlimited. therefore, contractors require simpler and quicker techniques which would enable them to forecast cash flowwith reasonable accuracy. forecasting s-curves in constr...

The problem of identifying the planar Pythagorean-hodograph curve that is “closest” to a given Bézier curve, and has same end points (or tangents), considered. “closeness” measure employed in this context root-mean-square magnitude differences between pairs corresponding control for two curves. methodology developed quintic PH curves, although it readily generalizes curves higher degree. Using ...
