A One-Dimensional Blocking Index Becomes Two-Dimensional Using GIS Technology

Protecting Surfaces Using One-Dimensional Nanostructures

Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

Visualization of three-dimensional GIS objects using rapid prototyping technology

To build multicolored physical models of three-dimensional cartographic objects, such as city models, landscape with relief or conceptual surfaces, computer-controlled devices can be used which were developed for the fast and inexpensive production of mechanical parts. The main groups of rapid prototyping technology – aggregation, removal and, transformation – are presented, including the machi...

Solving a class of nonlinear two-dimensional Volterra integral equations by using two-dimensional triangular orthogonal functions

In this paper, the two-dimensional triangular orthogonal functions (2D-TFs) are applied for solving a class of nonlinear two-dimensional Volterra integral equations. 2D-TFs method transforms these integral equations into a system of linear algebraic equations. The high accuracy of this method is verified through a numerical example and comparison of the results with the other numerical methods.
