Post crisis Strategies: Antifragility Principles as Catalysts for Urban Evolution Towards Sustainability
Urban crises reveal the true essence of cities: their ability to either withstand disorder or collapse under its pressure. This article explores how antifragility principles can transforms urban disruption into levers for reinforcement and innovation. While resilience seeks to restore a lost balance, antifragility goes further: it pushes cities to improve through shocks. Across a critical analysis of post-crisis strategies and the identification of fifteen fundamental theoretical principles, th…

Evaluating the Quality of Open Building Datasets for Mapping Urban Inequality: A Comparative Analysis Across 5 Cities
While informal settlements lack focused development and are highly dynamic, the quality of spatial data for these places may be uncertain. This study evaluates the quality and biases of AI-generated Open Building Datasets (OBDs) generated by Google and Microsoft against OpenStreetMap (OSM) data, across diverse global cities including Accra, Nairobi, Caracas, Berlin, and Houston. The Intersection over Union (IoU), overlap analysis and a positional accuracy algorithm are used to analyse the simil…

Interesting that while Abundant SF's head is taking shots at Zohran, Abundance New York endorsed him.
(Fifth, but they still favored him over Cuomo. They said "Zohran Mamdani is more likely to prioritize the central crises facing New Yorkers.")

Todd David, the political director of Abundant SF who helped elect moderates to the San Francisco Democratic Party, said New York could be in for a bumpy ride. "If Mamdani ultimately becomes the mayor, I do think New York is going to struggle," David said. "It's very hard to govern urban centers from the left. New York could really struggle with its business community, and public safety would probably take a hit."

Arc Routing Problems with Multiple Trucks and Drones: A Hybrid Genetic Algorithm
Arc-routing problems underpin numerous critical field operations, including power-line inspection, urban police patrolling, and traffic monitoring. In this domain, the Rural Postman Problem (RPP) is a fundamental variant in which a prescribed subset of edges or arcs in a network must be traversed. This paper investigates a generalized form of the RPP, called RPP-mTD, which involves a fleet of multiple trucks, each carrying multiple drones. The trucks act as mobile depots traversing a road netwo…
