Drivers in urban neighborhoods who patrol streets, seeking inexpensive on-street parking create a significant fraction of measured traffic congestion. The pool of drivers patrolling at any time can be modeled as a queue, where ‘queue service’ is the act of parking in a recently vacated parking space and queue discipline is SIRO – Service In Random Order. We develop a queueing model of such driv...

The seminal work by Sadi Carnot in the early nineteenth century provided blueprint of a reversible heat engine and celebrated second law thermodynamics eventually followed. Almost two centuries later, quest to formulate quantum theory thermodynamic laws has thus unsurprisingly motivated physicists visualize what are known as ‘quantum thermal machines’ (QTMs). In this article, we review prominen...

This article revisits aspects of Thermodynamics’ history by applying the Cartesian conception a machine to Sadi Carnot’s work. By defining mechanically geometric curves, Descartes placed mechanical science at centre geometry and natural philosophy. With this, autonomous - product this starts correspond an operational definition with power understand generate new ideas in addition general explan...

This research explores the correlation between ‘walkability’ and the ‘sense of place’ in Tehran’s streets, particularly streets leading to the Imam Khomeini square (Maidan-e Tup-khana) at the heart of historic downtown. The goal is to evaluate the walkability through a measurable method in order to prioritize strategies to enhance various aspects of the historic districts. After reviewing the e...
