Environmental exposures may increase a child's risk of developing asthma and also may increase the risk of asthma exacerbations. This article reviews several environmental exposures and suggests whether they contribute to asthma prevalence, asthma exacerbations, or both. Outdoor air exposures and violence are not likely to cause the increase in asthma prevalence. Exposure to outdoor air polluta...

The objective of this article was to discuss a series of issues pertaining to outdoor sex work practiced by low-income travestis in São Paulo, Brazil. Qualitative methods conducted among this segment of the population revealed sex work as almost inseparable from the existence of travestis as a social group. Among them, the outdoor modality was the most prominent and social stigma was a predispo...

This paper investigates the use of the FAB-MAP appearance-only SLAM algorithm as a method for performing visual data association for RatSLAM, a semi-metric full SLAM system. While both systems have shown the ability to map large (60-70km) outdoor locations of approximately the same scale, for either larger areas or across longer time periods both algorithms encounter difficulties with false pos...

This paper describes a system to extract salient regions from an outdoor image and match them against a database of previously acquired landmarks. Region saliency is based mainly on color contrast, although intensity and texture orientation are also taken into account. Remarkably, color constancy is embedded in the saliency detection process through a novel colorratio algorithm that makes the s...

The focus of the research is mega-block in New Belgrade built in 1960`s, before and after transformation. The aim of research was to compare the parameters of bioclimatic urban design before and after the intervention. The results show decrease due to shading and evapotranspiration of 1°C to 2°C, in the central part of communal open space and increase of temperature along the edges of the block...

This research aims to obtain 3D information by using spatio-temporal analysis of omni images for outdoor navigation and map-making in the intelligent transportation system (ITS) application. Two types of omnidirectional cameras are employed to make a spatio-temporal volume, which is a sequence of omni images stacked in the spatio-temporal space. For the spatio-temporal analysis of an omni image...

INTRODUCTION Information and communication technology (ICT) is potentially mature enough to empower outdoor and social activities in dementia. However, actual ICT-based devices have limited functionality and impact, mainly limited to safety. What is an ideal operational framework to enhance this field to support outdoor and social activities? METHODS Review of literature and cross-disciplinar...

In this paper, we propose a novel, effective and fast method to obtain a color illumination invariant and shadow-free image from a single outdoor image. Different from state-of-the-art methods for shadow-free image that either need shadow detection or statistical learning, we set up a linear equation set for each pixel value vector based on physically-based shadow invariants, deduce a pixel-wis...

The basic receive space diversity combining methods, i.e. Maximum Ratio Combining (MRC), Equal Gain Combining (EGC) and Selection Combining (SC), are studied in this work for Preand PostDFT combining wideband multi-carrier receivers. A common system model for both these schemes are devised. The outage and mean capacity and Frame Error Rate (FER) simulations show that Pre-DFT combining technique...
