Abstract: A conjugate gradient search method is coupled with a general model for the ultimate strength of a rectangular reinforced concrete (RC) cross section. Reinforcement required to provide reliable resistance identically equal ...

Abstract: A complete methodology to predict water distribution in laterals and units of subsurface drip irrigation (SDI) is proposed. Two computer programs have been developed for the hydraulic characterization of SDI; one for ...

Abstract: The performance of drip irrigation and subsurface drip irrigation (SDI) laterals has been compared. Two emitter models (one compensating and the other noncompensating) were assessed. Field tests were carried out with a ...

Abstract: Many bamboo species are well regarded for their strength and rapid renewability, although the nonuniformity of bamboo poles has impeded use in developed countries. Described herein are the results of a pilot effort to ...
