Improving Indoor Microbiological Measurements for Health Protection

Microbiological agents as health risks in indoor air.

Ambient air may be contaminated with or carry significant levels of a variety of potentially harmful microorganisms. There are three major sources of such microbes: a) those arising from microbial decomposition of various substrates associated with particular occupations (e.g., "moldy" hay leading to hypersensitivity pneumonitis), b) those associated with certain types of environments (e.g., Le...

Improving the Indoor Environment for Health, Well-being and Productivity

This paper selectively reviews scientific research on the positive effects on building occupant’s health, well-being and productivity that result from the presence of indoor plants in the workplace. Case studies show improvement in indoor air quality, (with a reduction in the levels of volatile organic compounds (VOCs), improved productivity by up to 12%, and reduced absenteeism and staff turno...

Indoor Aerosols: A Serious Threat for Human Health

Indoor Positioning and Pre-processing of RSS Measurements

Rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. Among different techniques, RSS-based  schemes and in particular oneof its variants which is based on Graph-based Semi-Supervised Learning (G-SSL) are widely-used approaches The superiority of this scheme is that it has low setup/training cost and at the same ti...
