Increasingly, policymakers in Europe and around the world are realizing the importance of healthy indoor environments for public health. Certain member states of the European Union (EU) have already achieved successes in improving indoor environmental quality, such as controlling certain contaminants (e.g., environmental tobacco smoke) or developing nationwide policies that address indoor air g...

Indoor environments are characterized by several pollutant sources. As people typically spend more than 90% of their time in indoor environments. Thus, indoor air quality (iAQ) is recognized as an important factor to be controlled for the occupants’ health and comfort. The majority of the monitoring systems presently available is very expensive and only allow to collect random samples. This wor...

We seek to predict the 6 degree-of-freedom (6DoF) pose of a query photograph with respect to a large indoor 3D map. The contributions of this work are three-fold. First, we develop a new large-scale visual localization method targeted for indoor environments. The method proceeds along three steps: (i) efficient retrieval of candidate poses that ensures scalability to large-scale environments, (...

This article presents a new approach to robot localization in indoor environments. The system presents a Monte Carlo method using SIFT for the visual step. The scope of the system is indoor environments where no artificial landmarks are necessary. The complete pose < x, y, θ > can be obtained. Results obtained in the RobotVision@ImageCLEF competition proved the goodness of the algorithm.

Volatile organic compounds (VOCs) are ubiquitous in indoor environments. Inhalation of VOCs can cause irritation, difficulty breathing, and nausea, and damage the central nervous system as well as other organs. Formaldehyde is a particularly important VOC as it is even a carcinogen. Removal of VOCs is thus critical to control indoor air quality (IAQ). Photocatalytic oxidation has demonstrated f...

Abstract The genus Aspergillus, which consists of a few hundred opportunistic mold species found in various climatic conditions, causes diseases including localized infections, fatal diseases, allergic responses, and inhaled conidia in humans. Herein, we present an overview of the most common diseases and allergic infections caused by Aspergillus species and their associated health hazards ...
