Libraries consist of large indoor open spaces with comfortable environments for studying activities. Hence, library occupants are exposed to microclimatic conditions in the environment library. This problem can lead a series thermal condition symptoms (cold or hot) and general discomfort. Therefore, this study aimed develop computational fluid dynamic (CFD) model validated field measurement dat...

This article presents an optimized prediction model of building dynamic HVAC system load, which simplifies the input parameters while meeting accuracy requirements results. The was established using open-source Modelica-based library, and linear aggregation method used to establish model. A reduced-order developed, simplified models verified. control strategy constructed indoor mean radiant tem...

The aim of this study was to determine the effect of different types of composites (Filtek Z250, Esthet X and Filtek Supreme) and dentin thicknesses (0.5 or 1.0 mm) on the generation of heat during photoactivation by QTH (conventional halogen light), LED (light emitting diode), and PAC (xenon plasma light) light-curing units. Temperature changes were recorded with a thermocouple type K connecte...

The total spectral radiant flux scale has been realized at National Institute of Standards and Technology using a goniospectroradiometer for the 360 nm to 800 nm region. The construction of the goniospectroradiometer and results of the scale realization as well as the uncertainty budget are presented. Introduction. There are increasing needs for total spectral radiant flux standards, which are ...

The human baby, even if premature, shows evidence of homeothermy (Bruck, 1961; Day, Curtis, and Kelly, 1943). When subjected to a cool environment, his metabolic rate increases in an attempt to keep pace with increased heat loss. When subjected to an excessively warm environment, he becomes restless and active with hurried panting respiration so that again metabolic rate is increased. Between t...

This article analyzes students' opinions about thermal comfort in air-conditioned classrooms. field study monitored and recorded the following variables: Air temperature (°C), Mean radiant Humidity (%), velocity (m/s). In addition, a survey was answered by 169 students to collect sensation preferences according ASHRAE sensory scale. The results show neutral found from votes 28.2°C with 98% of f...
