The urban experience " An inhabited place of greater size, population, or importance than a town or village " is the Merriam-Webster Dictionary entry for " city ". Most definitions, unless referring to very particular usages (e.g.: The City as London's financial district), convey the concept of a status granted to a relatively permanent, organized human settlement. The Chambers Dictionary inclu...

Cities have an ever increasing wealth of sensing capabilities, recently including also Internet of Things (IoT) systems. However, to fully exploit such sensing capabilities with the aim of offering effective citysensing-driven applications still presents certain obstacles. Indeed, at present, the main limitation in this respect consists of the vast majority of data sources being served on a “be...

Smart cities are demanding solutions for improved traffic efficiency, in order to guarantee optimal access to mobility resources available in urban areas. Intelligent video analytics deployed directly on board embedded sensors offers great opportunities to gather highly informative data about traffic and transport, allowing reconstruction of a real-time neat picture of urban mobility patterns. ...

BACKGROUND We sought to describe differences in individual and structural vulnerabilities faced by female sex workers (FSWs) in Pakistan between 2006 and 2011, and to characterise risk factors for inconsistent condom use and HIV prevalence in this population. METHODS To describe differences in vulnerabilities, we analysed behavioural data from serial cross-sectional surveys conducted across n...

In this paper, we present a new approach for shape-grammar-based generation and rendering of huge cities in real-time on the graphics processing unit (GPU). Traditional approaches rely on evaluating a shape grammar and storing the geometry produced as a preprocessing step. During rendering, the pregenerated data is then streamed to the GPU. By interweaving generation and rendering, we overcome ...

The strong world-wide urbanisation trend calls for a repositioning of cities, especially the large cities with a global impact. These cities tend to become economic, logistic and political powerhouses and are increasingly involved in a competition on their integral performance. The present paper aims to trace to what extent and why some cities outperform others. Starting from an extensive datab...

OBJECTIVES The objective of this paper is to provide a detailed description of Internet-based sexually transmitted disease/human immunodeficiency virus prevention in the 8 US cities most affected by syphilis in men who have sex with men. GOAL By reviewing the efforts under way in these 8 cities, we will understand the barriers and facilitators associated with Internet-based prevention efforts...
