Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images.Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DI...

background : noise pollution and workers' noise exposure are common in industrial factories in iran. in order to reduce this noise pollution, evaluation and investigation of noise emission are both necessary. in this study, different noise mapping methodsare used for determining the distribution of noise.   materials and methods : in the present study, for preparing a noise map in a hall o...

Corrosion in general is a complex interaction between water and metal surfaces and materials in which the water is stored or transported. Water quality monitoring in terms of corrosion and scaling is crucial, and a key element of preventive maintenance, given the economic and health hurts caused by corrosion and scaling in water utilities. The aim of this study is to determine the best model fo...

Interpolation operators map a function u to an element Iu of a finite element space. Unlike more general approximation operators, interpolants are defined locally. Estimates of the interpolation error, i.e., the difference u− Iu, are of utmost importance in numerical analysis. These estimates depend on the size of the finite elements, the polynomial degree employed, and the regularity of u. In ...

drought monitoring and evaluation in water resources systems, are basic steps in systems analysis aswell as the optimal water resources allocation for different demands. therefore, in this study, whole of irancountry was selected as the study area, and it was attempted to determine the simultaneous droughts whichhad been occurred in the period of 1981-2010, using monthly rainfall data of 31 syn...

There has been much excitement and activity in recent years related to the relatively sudden availability of earth-related data and the computational capabilities to visualize and analyze these data. Despite the increased ability to collect and store large volumes of data, few individual data sets exist that provide both the requisite spatial and temporal observational frequency for many urban ...
