The importance of this study may be defined by using the smart techniques to earned value indicators of residential buildings projects in Republic of Iraq, only one development intelligent forecasting model was presented to predict Schedule Performance Index (SPI), Cost Performance Index (CPI), and To Complete Cost Performance Indicator (TCPI) are defined as the dependent. The approach is principally influenced by the determining numerous factors which effect on the earned value management, that involves Iraqi historical data. In addition, six independent variables (F1: BAC, Budget at Completion., F2: AC, Actual Cost., F3, A%, Actual Percentage., F4: EV, Earned Value. F5: P%, Planning Percentage., and F6: PV, Planning Value) were arbitrarily designated and satisfactorily described for per construction project. It was found that ANN has the capability to envisage the dust storm with a great accuracy. The correlation coefficient (R) has been 90.00%, and typical accuracy percentage has been 89.00%.

In this study, new series of superabsorbent polymers, which were free of acrylate cross-linkers, were synthesized and their absorbent properties were evaluated. The new superabsorbent polymers showed high free swell and absorbency under loading. They were synthesized in a single-step process through a solution polymerization of partially neutralized acrylic acid in the presence of cross-linking agents allyl sucrose (AS) and epoxy allyl sucrose (EAS). Allyl sucrose was synthesized by reacting sucrose with allyl chloride in an alkaline medium. Allyl sucrose was then converted into EAS by oxidation with peracetic acid. The synthesis and absorbent properties of superabsorbent polymers (SAPs) cross-linked with commercially available non-sucrose-based epoxy cross-linking agents, e.g., glycerol diglycidyl ethers (GDGE), 1,4-butanediol diglycidyl ether (1,4-BDGE) and 1,4-cyclohexanedimethanol diglycidyl ether (1,4-CHDDMDGE) have been evaluated, as well. Absorbent properties of the prepared superabsorbent polymers were evaluated in saline solution and results showed high dependency of the absorbent properties on the cross-linking agent polarity and concentration. Superabsorbent polymers cross-linked with EAS and GDGE showed the highest absorbency under loading and indicated that they formed gels with high strength in the aqueous solution. Absorbent properties of the prepared SAPs showed reversible correlation with cross-linking agent concentration. The pH of the reaction mixture was optimized to achieve the highest free swell and absorbency under loading. The biodegradation properties of the superabsorbent polymers cross-linked with sucrose-based cross-linking agents were also evaluated and they showed degradation behavior under the influence of organisms Pseudomonas aeruginosa and Trichophyton rubrum.
