In the recent century,Tehran has been confronted with urban sprawl and rapid population growth that have caused urban landscape transformation, whichis different in various parts of Tehran based on specific economic, cultural and social situations. What is important in this essay is the human perception of their landscape in this process of transformation; therefore, the purpose is analyzing la...

In seismic images, the opaque oscillatory nature of the ever present sedimentary layers often hide the boundaries between sedimentary packages, such as faults or river channels. Interpreters painstakingly identify these boundaries by inspecting individual planes of the image volume. Discontinuity attribute maps computed from image volumes depict these boundaries and greatly simplify and acceler...

Discontinuity meshing has greatly enhanced the visual and numerical accuracy of radiosity solutions. However, its computational expense means that it cannot be used in dynamic interactive environments with current hardware. Techniques are proposed which allow the discontinuity information to be reused as the environment changes. These techniques complement existing dynamic radiosity methods whi...

Information and communication technologies (ICT) are now an integral part of our environment and are among the most important drivers for innovation in many industry sectors. Whether complex control technologies in the field of machine tools, fly-by-wire systems in the aircraft industry or intelligent components in modern cars, everyday life without ICT is no longer conceivable. Moreover, the c...

Despite the close affinity between collective memory and urban structures as the relationship between what is hidden and what is visible; rapid changes throughout the city have caused a disconnection between integrated memories and landscape cohesion. As a context for memories, the historical urban landscape proves to be valuable. The present research seeks to identify elements and signs in urb...

Based on a detailed study of the return national-level planning in Argentina as embodied by COFEPLAN, national council, we develop conceptual framework to analyse possibilities and limits steering governance. We lean theoretical apparatus evolutionary governance theory use concepts goal dependency, interdependency, path dependency material (effects governance) reality effects strategy governanc...

We propose a new primal-dual framework for representation, capture, processing, and display of piecewise smooth surfaces, where the dual space is the space of oriented 3D lines, or rays, as opposed to the traditional dual space of planes. An image capture process detects points on a depth discontinuity sweep from a camera moving with respect to an object, or from a static camera and a moving ob...

Reconstruction of surface discontinuities from unorganized 3D points is a difficult problem. Both the polygonization and surface fitting approaches to surface reconstruction face the same chicken-and-egg problem: to correctly reconstruct surface discontinuities, the points that lie on the same side of the discontinuities should be used to reconstruct the surfaces to form the discontinuities. Ho...
