Bioaerosols such as bacterial and fungal cells and their spores are along with non-biological particles part of indoor airborne particulate matter and have been related since a long time to health issues of human beings as well as flora, and fauna. To identify the different risks and to establish exposure thresholds, microbiology of air samples from a series of indoor environments must be chara...

As we realize that we spend most of our time in increasingly complex indoor environments, applications to assist indoor activities (e.g. guidance) have gained a lot of attention in the recent years. The advances in ubiquitous computing made possible the development of several spatial models intending to support context-aware and fine-grained indoor navigation systems. However, the available mod...

In this contribution a DC magnetic signal based positioning system is presented which shows no special multipath effects and has excellent characteristics for penetrating various obstacles. The proposed system allows high ranging resolution in indoor environments by using adaptive signal processing algorithms. Keywords—Indoor Positioning; Localization; Magnetic Indoor Local Positioning System, ...

Unencumbered location tracking is becoming increasingly important, especially in indoor pervasive environments. In this paper, we describe an unencumbered indoor location tracking system with a high hit rate that uses a network of embedded floor sensors to determine user location.

Background: A common concern of the poultry industry is the presence of fungal pathogens in the birds’ environment, which may constitute a considerable health hazard to the birds, farmers, and those living in proximity of the farm. OBJECTIVES: The aims of this study were to assess the mycoflora in the indoor and outdoor environments of poultry breeding houses and studying the efficacy of disinf...

Overview. In this project, I plan to investigate techniques that will enable unmanned aerial vehicles (UAVs) to autonomously explore an indoor environment. While UAVs are currently used extensively in outdoor environments for various applications, including wildfire monitoring [1], agricultural surveying [2], and traffic management [3], their use in indoor applications have been fairly restrict...

Recent advances have allowed for the creation of dense, accurate 3D maps of indoor environments using RGB-D cameras. Some techniques are able to create large-scale maps, while others focus on accurate details using GPU-accelerated volumetric representations. In this work we describe patch volumes, a novel multiple-volume representation which enables the creation of globally consistent maps of i...

background: hospital is a place to provide medical services. it is affected by noise pollution sources that can be associated with negative impacts on health and comfort status of the staff members and patients. the aim of this study was to measure noise levels in different wards of hospitals and to determine the irritation caused by noise among the hospital staff members in hamadan, iran. meth...
