The use of digital technologies and methods mathematical modeling allows modern architects to design the cities that have their own unique style harmoniously fit into environment. It is necessary widely introduce three-dimensional practice for more effective urban space creation development.

Ship behavior is the semantic expression of corresponding trajectory in spatial-temporal space. The intelligent identification ship critical for safety supervision waterborne transport. In particular, complicated reflects long-term intentions a ship, but it challenging to recognize automatically computers without proper understanding. For this purpose, study provides method model from perspecti...

Binary Space Partition (BSP) tree and Constructive Solid Geometry (CSG) tree representations are both set-theoretic binary tree representations of solid objects used in solid modeling and computer graphics. Recently, an extension of the traditional BSP tree definition has been presented, in which surfaces used in the binary partition include curved surfaces in addition to planar surfaces. We ex...

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...

the synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. to provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...
