Otherwise, presumed-either behaves much like the widely-used presumed-abort protocol.

This paper seeks to investigate a new definition for architecture by unifying the three Vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. The paper is composed in two main sections. The first section investigates the nature of architecture based on the mentioned principles, where a...
