We explore geometry of London’s streets using computational mode of an excitable chemical system, Belousov-Zhabotinsky (BZ) medium. We virtually fill in the streets with a BZ medium and study propagation of excitation waves for a range of excitability parameters, gradual transition from excitable to subexcitable to non-excitable. We demonstrate a pruning strategy adopted by the medium with decr...

The Dark Net has changed the way drugs are traded globally by shifting trade away from streets and onto web. In this paper, I study whether shutdown of marketplaces an impact on amount in crimes that normally associated to street drug dealing. To identify a causal effect, use daily data US exploit unexpected shutdowns large online trading platforms. regression discontinuity design, compare crim...

F the early 1900s to the late 1940s, road networks in South Australia were developed on the rectangular grid system as an extension to the original planning of early towns and villages. With the advent of the automobile and sealed pavements, most local government authorities constructed a sealed central strip approximately 6 meters wide with wide footpaths and verges around existing street tree...

This study presents temporal and spatial variations in personal exposure of parking attendants in a busy conurbation in the northern part of the UK. Two traffic related pollutants carbon monoxide (CO) and ultrafine particulates (UFP), mainly associated with urban drives, have been considered for two distinct locationsone, in the city centre and the other in a suburban area of Leeds, a prominent...

Humans live interacting with other people and do everyday tasks in individual and collective ways. Robotics people are interested in building robots that can interact with people in the same way that humans do. In order to reach this goal robots must learn from the interaction with humans and learn the human skills used in everyday life to acquire robot social behaviors that can then be used in...
