ambient assisted living is an area of interest because of the potential for aid in needs and difficulties for the elderly or disabled. These systems have the potential to help control medication intake up to saving lives by complex monitoring. In this type of monitoring, an indoor localization system is necessary. We propose an indoor localization system based on existing WiFi networks, which d...

Video surveillance of public spaces is a feature modern society that has expanded quite quickly and in pervasive way during the last decades becoming fundamental need for both individual collective security. But, as sophistication this type systems increases, concern about threat to individuals’ right privacy raises well. Indeed, video could breach personal because location clearly one most sen...

A culture-based colony counting method is the most widely used analytical technique for monitoring bioaerosols in both indoor and outdoor environments. However, this method requires several days for colony formation. In this study, our goal was fast monitoring (Sampling: 3 min, Detection: < 1 min) of indoor bioaerosol concentrations with ATP bioluminescence assay using a bioaerosol sampler. For...

background: radon is the second leading cause of lung cancer after smoking. in canada, the health authorities have no access to comprehensive profile of the communities built over uranium-rich micro-geological settings. the present indoor radon monitoring guideline is unable to provide an accurate identification of health hazards due to discounting several parameters of housing characteristics....

A key application of sensor networks in smart environments is in monitoring activities of people. We develop several scenarios in which ultrasonic sensors are used for patient and elderly monitoring. In each scenario, we apply different algorithms for data fusion and sensor selection using quality-based or time division approaches. We have devised trajectory-matching algorithms to classify traj...

NO₂ and particulate matter are the air pollutants of most concern in Ireland, with possible links to the higher respiratory and cardiovascular mortality and morbidity rates found in the country compared to the rest of Europe. Currently, air quality limits in Europe only cover outdoor environments yet the quality of indoor air is an essential determinant of a person's well-being, especially sinc...

Children spend a large amount of time in school environments and when Indoor Air Quality (IAQ) is poor, comfort, productivity and learning performances may be affected. The aim of the present study is to characterize IAQ in a primary school located in Taranto city (south of Italy). Because of the proximity of a large industrial complex to the urban settlement, this district is one of the areas ...
