Accessibility metrics have been increasingly employed as a tool to explore the social impacts of transport systems and policies. However, few empirical studies accessibility involve comparisons between cities from countries with different levels development, in particular, across Global South North. This paper attempts bridge this gap by focusing on two very distinct, but similarly sized, large...

Nowadays, emergency departments in many countries still rely on human operators to allocate rescue resources to emergency events. However, with the fast growth of population in metropolitan regions, the frequency of occurrence of emergency events has risen significantly, which imposes tremendous pressure over emergency event operators. Agent and multi-agent systems (MASs) provide potential solu...

OBJECTIVE Due to their toxicity, diesel emissions have been submitted to progressively more restrictive regulations in developed countries. However, in Brazil, the implementation of the Cleaner Diesel Technologies policy (Euro IV standards for vehicles produced in 2009 and low-sulfur diesel with 50 ppm of sulfur) was postponed until 2012 without a comprehensive analysis of the effect of this de...

The rescue operations for emergency events usually require multiple emergency departments to cooperate with each other to provide effective and efficient resource allocation plans within a short time limit and dynamically adjust the plans as necessary. In the paper, an agent-based resource allocation approach is proposed to automatically allocate rescue resources to concurrent emergency events ...

It has been argued that the effects of the desegregation of public schools from the late 1960s onward were limited and short-lived, in part because of white flight from desegregating districts and in part because legal decisions in the 1990s released many districts from court orders. Data presented here for 1970-2000 show that small increases in segregation between districts were outweighed by ...

This paper investigates the effects of national and regional economic conditions on outcomes in the single-family housing market: housing prices, vacancies, and residential construction activity. Our three-equation model confirms the importance of changes in regional economic conditions, income, and employment on local housing markets. The results also provide the first detailed evidence on the...

In this article, we examine the existence of regions and borders in Belgium by means of an original data set of more than 200 million mobile communications and a mathematical method which allows networks to be divided into coherent groups in a natural and automatic manner. A geography of mobile communications is thus proposed based on the relative frequency of communications as well as their av...

In this paper we present a simple and new algorithm that tracks the contour of several homogenous regions in a sequence of images. The method exploits the fact that, when i.e. observing a moving object (exposing a homogenous region), the regions in two consecutive frames often overlap. We show that the method is valuable for the RoboCup domain: It allows to track the green playing field and the...

 The European Medicines Agency has cleared the world' s first malaria vaccine, prior to prior to its approval for use in Africa. The vaccine (Mosquirix) was developed by Glaxo-SmithKline, who have pledged not to profit from the vaccine. It is designed to target infection in children in Africa, although it does not appear to be very effective in protecting young babies – children aged 5–17 mon...
