this paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (ccfst) stub columns under axial loading condition based on artificial neural networks (anns) by using a large wide of experimental investigations. the input parameters were selected based on past studies such as outer diameter of column, compressive strength...

The paper studies bilateral contracting with endogenous property rights. Players engage in costly ex post adjustment of ex ante contract. After ex ante agreement on surplus sharing, players invest irreversibly production. Player costs of altering ex ante contract are transaction costs of three kinds: measurement, information and enforcement costs. Each player chooses an action which incurs tran...

In the absence of investment and dividend payments, the surplus is modeled by a Brownian motion. But now assume that the surplus earns investment income at a constant rate of credit interest. Dividends are paid to the shareholders according to a barrier strategy. It is shown how the expected discounted value of the dividends and the optimal dividend barrier can be calculated; Kummer’s confluent...

carrot contains valuable and healthy material. beta carotene pigments and antioxidants on it are so effective against free radicals in body. formulation of novel fruity products is object of some investigations and in parallel of it, have been used different compositions of hydrocolloids and others additional material in its formulations. in addition we can use the low edible quality of carrots...
