Westernization has propelled changes in urbanization and architecture, altering our exposure to the outdoor environment from that experienced during most of human evolution. These changes might affect the developmental exposure of infants to bacteria, immune development, and human microbiome diversity. Contemporary urban humans spend most of their time indoors, and little is known about the mic...
This paper presents a car parking monitoring system using a wireless sensor network. The presented sensor network has a line-shaped topology and adopts a TDMA-based protocol for allowing multi-hop communications. Sensor nodes are deployed in the ground of an outdoor parking lot in such a way that a sensor node monitors a parking space. Each sensor node detects the availability of the associated...
This study focused on changes in residents’ uses and awareness of outdoor spaces due to the spread COVID-19 pandemic. The aim was gain understanding following three aspects people’s behaviors believed have been greatly affected before Emergency Declaration Japan during State Emergency: 1) how people use spaces, 2) demands with respect future. In addition, as a byproduct this investigation, aims...
Performing foreground / background segmentation in outdoor scene is very challenging. Starting from a stateof-the-art color-based approach [8], we propose three improvements: the use of the YCoCg color space, a spherical association volume, and a cast shadows management approach. Using image sequences with ground truth at pixel-level, we quantitatively measured the performances of the proposed ...
This paper deals with the evaluation of the outdoor performances of a composite roof, composed of a corrugated iron rooftop, a radiant barrier and a ceiling made of wood, each component being separated by an air space. This assembly is mounted on a small-scale test cell, named Isotest, designed and set up for research purposes. Isotest is installed on an experimental platform, dedicated to the ...
The ability of observers to perceive distances and spatial relationships in outdoor environments was investigated in two experiments. In experiment 1, the observers adjusted triangular configurations to appear equilateral, while in experiment 2, they adjusted the depth of triangles to match their base width. The results of both experiments revealed that there are large individual differences in...
This paper introduces a signal-recognition based approach for detecting autonomous mobile robot immobilization on outdoor terrain. The technique utilizes a support vector machine classifier to form class boundaries in a feature space composed of statistics related to inertial and (optional) wheel speed measurements. The proposed algorithm is validated using experimental data collected with an a...
