Positioning data offer a remarkable source of information to analyze crowds urban dynamics. However, discovering urban activity patterns from the emergent behavior of crowds involves complex system modeling. An alternative approach is to adopt computational techniques belonging to the emergent paradigm, which enables self-organization of data and allows adaptive analysis. Specifically, our appr...

Limited availability of the Global Navigation Satellite System (GNSS) signals in urban canyons is a preventive factor for implementing many position-based systems. Specifically for vehicles, a variety of applications such as Intelligent Transportation Systems (ITS), navigation, and Location-Based Services (LBS) are not properly functional in dense urban areas due to constrained visibility of th...

Evapotranspiration of urban street trees is essential in mitigating heat islands due to its cooling effect. However, current shifts rainfall and temperature regimes towards drier hotter periods Central Europe have caused substantial water stress for trees. Quantifying subsequently managing these changing dynamics as well estimating evapotranspiration availability necessary but at the same time ...

A general proecological urban road traffic control idea for the street canyon is proposed with emphasis placed on development of advanced continuum field gasdynamical (hydrodynamical) control model of the street canyon. The continuum field model of optimal control of street canyon is studied. The mathematical physics' approach (Eu-lerian approach) to vehicular movement, to pollutants' emission,...

Radio frequency identification (RFID) technology has become one of the most prosperous positioning technologies due to its advantages in non-contact and non-line-of-sight sensing. Most of the current positioning applications using RFID were implemented by setting a few RFID readers in some known locations, which were only suitable for the indoor or small area of outdoor positioning. This paper ...

A scheme that couples a detailed building energy model, EnergyPlus, and an urban canopy model, the Town Energy Balance (TEB), is presented. Both models are well accepted and evaluated within their individual scientific communities. The coupled scheme proposes a more realistic representation of buildings and heating, ventilation and air-conditioning (HVAC) systems, which allows a broader analysi...

BACKGROUND Developmental instability of shelled gastropods is measured as deviations from a perfect equiangular (logarithmic) spiral. We studied six species of gastropods at 'Evolution Canyons I and II' in Carmel and the Galilee Mountains, Israel, respectively. The xeric, south-facing, 'African' slopes and the mesic, north-facing, 'European' slopes have dramatically different microclimates and ...

In 2009, two workshops exploring urban informatics were held: one at Pennsylvania State University, University Park, and the other at the Queensland University of Technology, Brisbane. Research and inquiry into the changing landscape of technology-enabled engagement with communities, cities and spaces was presented at both of these events. From these gatherings of international scholarship and ...
