Mastering the relationship between urban landmarks and space morphology in planning, landscape architectural design helps maintain intelligibility of compact districts. The objective present study was to numerically determine structural salience various an environment use it interpret city. Combining measurement method 3D visibility related principles syntax, this develops a new Node–Landmark G...

introduction this study is dealt with the environmental planning from a bio-cybernetic and hierarchical systems viewpoint within the context of landscape ecology. this viewpoint requires not only knowledge of the science of ecology but also ecological wisdom in order to recognize the place of humankind in nature. the conceptual and practical approach which is provided will help landscape planne...

We consider visibility graphs involving bars and arcs in which lines of sight can pass through at most k objects. We prove a new edge bound for arc k-visibility graphs, provide maximal constructions for arc visibility graphs and semi-arc k-visibility graphs, and give a complete characterization of semi-arc visibility graphs. We further show that the family of arc i-visibility graphs is never co...

We show that the segment endpoint visibility graph of any finite set of disjoint line segments in the plane admits a simple Hamiltonian polygon, if not all segments are collinear. This proves a conjecture of Mirzaian.

purpose: the purpose of this study was to investigate the structure of the discipline categorization and its overlap with isi subject categories. this will help detect the systematic errors arising from the scientometrics studies. methodology: the scientometrics methodology was used. all articles which were indexed in the web of science database (2007) and also the articles citing them during 2...
