for calculation of the displacements of points in micro geodesy networks, it is essential to discover stable and unstable points. without knowing stable points, calculated displacements are due to datum deficiency. in this case, calculated displacements are not valid. there are two methods to discover stable and unstable points: a-congruency robust method b- l1 norm minimization in this study t...
this study aimed to find an appropriate way to minimize water utility in the petrochemical and petroleum industries. for this purpose, tehran oil refinery was chosen to analyze feasibilities of regeneration, reuse and recycling in the water network. in this research, two key contaminants including cod and hardness were analyzed. amount of freshwater was reduced about 180 m3/h (53%) and 216.88 m...
This paper gives a general convergence analysis to the truncated incomplete Hessian Newton method (T-IHN). It shows that T-IHN is globally convergent even with an indefinite incomplete Hessian matrix or an indefinite preconditioner, which may happen in practice. It also proves that when the T-IHN iterates are close enough to a minimum point, T-IHN has a Q-linear rate of convergence, and an admi...
