This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability. It turns out that the classical notion of the Witt ring of symmetric bilinear forms over a field makes sense in the context of {tmem{quadratically p...

Density is a critical typology in determining sustainable urban built-form patterns. Built-formrefers to the assemblage and arrangement of the building masses in a city reflecting the spatial layout of spaces.The relationship between density and urban character is also based on at certain densities (thresholds). In a widersense, sustainable cities are a matter of density. Recent debates about t...

ABSTRACT A vibrant and commercially active center is often the result of interesting, diverse building styles and or built-forms, pedestrian density along with variety of quality public places where people feel comfortable, spending time and shopping items for domestic and commercial functions in cities like Addis Ababa. The scale and design of buildings, pedestrian density, and other phy...

Sustainable settlement is one of the key constituents of sustainable development, and sustainable urban development can be defined in this framework. Emergence of sustainable development as a commonly-used phrase has caused several controversies about urban forms. Today’s urban form is known as a source of environmental problems. Undoubtedly, this phrase has persuaded many of researchers to sea...

This Study has discussed the meaning of public space and has shown that public spaces are an essential part of people’s lives. It has also identified the key urban design and architectural ideologies that have influenced the shape of the built environment, and has discussed how each has perceived the value of public spaces. In the following provides an overview of the relationship between peopl...
