matrix analysis of corrosion inhibition phenomena (macip), in which an inhibitor isconsidered as a point in a multi-dimensional virtual efficiency space, was performed on somepyridine derivatives. the needed molecular parameters such as homo and lumo energylevels, charge densities on hetero atom, dipole moment, heat of formation, and total energyvalues were obtained by means of semi-empirical q...

neural networks are applicable in identification systems from input-output data. in this report, we analyze thehammerstein-wiener models and identify them. thehammerstein-wiener systems are the simplest type of block orientednonlinear systems where the linear dynamic block issandwiched in between two static nonlinear blocks, whichappear in many engineering applications; the aim of nonlinearsyst...

In the present investigation, methanolic extract of Mimusops elengi  leaves were evaluated for wound healing activity. Entire wound healing process is complex series of events that begins at the moment of injury and can continue for months to years. Methanolic extract of Mimusops elengi leaves were examined for wound healing activity in the form of ointment by the excision, the incision and ...

In this paper power system model is represented in a new domain that relates to Multi-Resolution Analysis (MRA) space. By developing mathematical model of elements in this space using Galerkin method, a new alternative method for power system simulation in nonsinusoidal and periodic conditions is developed. The mathematical formulation and characteristics of new proposed space is expressed. Als...

Following the “spatial turn” of the last 3 decades in humanities and social sciences and the structure of semiotic object, this research studies space as the main semiotic object of Calvino’s (1972) Invisible Cities. Significance of this application resides in examining the possibility of providing a more concrete methodology based on the integration of Zoran’s (1984) 3 vertical levels of const...

pore network modeling uses a network of pores connected by throats to model the void space of a porous medium and tries to predict its various characteristics during multiphase flow of various fluids. in most cases, a non-realistic regular lattice of pores is used to model the characteristics of a porous medium. although some methodologies for extracting geologically realistic irregular network...

Urban green space is one of the important solicitude for urban planners and designers due to their effects on quality of life. This research used HPM model to estimate economic value of urban green space, in a case study of trees in Velenjak residential place, Tehran Metropolitan Area in Iran. View determined the spread tree on the public spaces and neighbourhoods improve residential lan...
