In this study, heat transfer and aerosol deposition in the under-floor and baseboard heating systems have been investigated, numerically. The aim of this study is a comparison between these heating systems. This comparison obtains the optimal heating system with low suspended particles in the air. Computational fluid dynamic with Eulerian-Lagrangian method has been used to simulate fluid and pa...

This paper describes a study of the performance of a ventilation system in a typical patient room using CFD modeling and calculations of various ventilation indices. The results show that the use of basboard heating is necessary in extreme weather conditions. In particular, good occupant conditions are virtually impossible to achieve without baseboard heating. Further, in general weather condit...

The objective of this study is to determine the most energy efficient and cost effective combination of architectural elements and mechanical systems to specify in an office building while maintaining a comfortable and healthy indoor environment for the occupants. A commercial office building located in the Minneapolis area with three heating, ventilating, and air-conditioning (HVAC) systems an...

BACKGROUND The fractional concentration of exhaled nitric oxide (FeNO) appears to be a good marker for airway inflammation in children with asthma. OBJECTIVE To evaluate the effect of environmental exposures on exhaled nitric oxide in a community sample of children. METHODS The relationship among exhaled nitric oxide, underlying disease and home environmental exposures was examined using qu...

In this paper, we present a system that allows emergency telephone calls to be made when a patient activates the alarm by pressing a button on the wireless ambulatory monitor. The system involves a triaxial accelerometer in-built to an RF (Radio Frequency) transmitter, RF receiver, telephone dialer module and a Personal Computer (PC) where data is stored for analysis. Introduction The telephone...

today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. fuzzycontrol is one of these methods which pr...

Fractional exhaled nitric oxide (FeNO) is a non-invasive marker of airway inflammation in asthma and respiratory allergy. Environmental factors, especially indoor and outdoor air quality, may play an important role in triggering acute exacerbations of respiratory symptoms. The authors have reviewed the literature reporting effects of outdoor and indoor pollutants on FeNO in children. Although t...
