ROUGHNESS CHARACTERIZATION OF AN INDOOR ENVIRONMENT

Study of Noise Map and its Features in an Indoor Work Environment through GIS-Based Software

Background: Noise mapping in industry can be useful to assess the risks of harmful noise, or to monitor noise in machine rooms. Using GIS -based software for plot of noise maps in an indoor noisy work environment can be helpful for occupational hygienists to monitor noise pollution. Methods: This study was carried out in noisy packaging unit of a food industry in Ghazvin industrial zone, to ev...

Remediation of ozone pollution by ornamental plants in indoor environment

The indoor air quality is much more matter of concern as relative to ambient or outdoor air quality, especially in the context of human health.  However, very few studies have been reported for remediation of indoor ozone by plant species. The main objective of this study is to evaluate ozone deposition velocities and ozone removal effectiveness of three indoor ornamental plant species (Dra...

Tracking human motion in an indoor environment

This paper presents an approach to tracking human motion in a sequence of monocular images. The process consists of detecting motion, segmenting moving subjects by recovering the background and, nally, tracking the subject of interest. The usual assumptions of small image motion, a xed viewing system and constant velocity are systematically relaxed. Two cases are studied: 1) a viewing system wi...

Multi Object Recognition in an Indoor Environment

Characterization of Reconfigurable MIMO Antennas for Channel Capacity in an Indoor Environment

In this paper, three different frequency reconfigurable multiple-input-multiple output (MIMO) antennas are characterized in terms of their channel capacity performance in an indoor environment. Two 2 × 2 and one 4 × 4 MIMO antenna configurations are investigated. A complete MIMO system is implemented using software defined radio (SDR) platform. The antenna under test can be used at either trans...
