Abstract The effective algorithms for calculating the theoretical profiles of gauge surfaces various bits have been developed, which reproduce such using spline functions with precision up to resolution graphic devices on modern computers. Execution profile surface close one (especially large-diameter displaced axes rolling cutters) can increase tool life by reducing loss diameter during bit pr...

Based on the cutting force theory, the cutting stress in end milling operation was predicted satisfactorily through simulation of using finite element method. The mechanistic force models were introduced in high accuracy force predictions for most applications. The material properties in the simulations were defined based on the cutting force theory, as a function of strain and strain rate wher...

A multivariate source-based morphometry (SBM) method for processing fractional anisotropy (FA) data is presented. SBM utilizes independent component analysis (ICA) and decomposes an FA image into spatial maps and loading coefficients. The loading coefficients represent the relative degree each component contributes to a given subject's FA map. We hypothesized that SBM analysis on a large datase...

In the earlier developed method of direct cutting-out, we take into account anisotropy material. This is based on procedure modeling finite or bounded bodies with thin structural defects any type and boundary conditions its contour by an infinite space same inhomogeneities as in original problem additional (cracks absolutely rigid inclusions), which form investigated body. Thus, loaded cracks a...

Introduction: The use of low energy isotopes such as  103 Pd in brachytherapy for the treatment of cancers  such as prostate, eye, head, neck, breast and cervix is increasing. In this regard, different models of Pd- 103  seeds  have  been  designed  and  manufactured  at  the  Agricultural,  Medical  and  Industrial  Research  School (AMIRS) of Atomic Energy Organization of Iran. In this resear...

geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. here we present the question: is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? the obtained answer is: yes. this investigation showed an agreeme...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

Background: The most common primary tumors of brain are gliomas. Grading of tumor is vital for designing proper treatment plans. The gold standard choice to determine the grade of glial tumor is biopsy which is an invasive method.Objective: In this study, we try to investigate the role of fractional anisotropy (diffusion anisotropy) and linear anisotropy ...
