The author deals with the analysis of urban open spaces, once conceived as part and parcel of our urban heritage. He introduces a mathematical modelling technique that is capable of mapping the variation of the sky visible from points distributed throughout space. The resulting maps overcome the limits of orthographic (plan, section, and elevation) and perspective methods of analysis by conside...

In this paper, we introduce the concept and an implementation of geospatial 3D image spaces as new type of native urban models. 3D image spaces are based on collections of georeferenced RGB-D imagery. This imagery is typically acquired using multi-view stereo mobile mapping systems capturing dense sequences of street level imagery. Ideally, image depth information is derived using dense image m...

Abstract ‘Urban Open Space' is an essential component of the urban landscape. “Green spaces” connect built structures to outdoors through open spaces. Controlling thermal conditions such as air temperature and radiation in outdoor areas can help modify microclimates. This study attempts establish importance landscape by analyzing various microclimate parameters their impact on The focus this re...

Nowadays space is considered to be a net of connections between different areas. The questions how to delineate its character and how it is possible to objectively compare two spaces is a matter under consideration. This was the reason for creating new theories about the structure of space. Space syntax analysis (SSA) or simply Space Syntax defines a number of theories and research areas devo...

Lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. By considering this importance and inexistence of a process for composing urban Lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. Reaching a suitable solution for Li...

In this paper, we have dened and studied a generalized form of topological vector spaces called s-topological vector spaces. s-topological vector spaces are dened by using semi-open sets and semi-continuity in the sense of Levine. Along with other results, it is proved that every s-topological vector space is generalized homogeneous space. Every open subspace of an s-topological vector space is...

Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development of urban ecology locally and globally. Different approaches have been used in the study of urban ecology of different urban areas in South Afric...

now days, citizens safety in urban spaces is one of the most important worries of urban managers. this may be reflected in different characters of urban spaces such as physical, social and economical and even political characters. with regard to increasing crimes and complexities of urban spaces, trying for achieve to sustainable, healthy and good cities mean in providing the safety environment...

With the wind permanent flow in the cities, obtaining the minimal pollution in the environment is accessible. Different policies have been considered for optimization of cities such as attachment and or reduction of building parts like air-traps, ceiling forms and so on. Due to population growth in cities and the increasing need for resettlement these people in the cities, inevitably, to the hi...
