| dc.description.abstract | This study develops and evaluates a modified apparent temperature (MAT) model, validates this model with physiological data reported in the literature and with Goldman's model of physiological responses. A simplified MAT (SAT) model is also developed. The primary results of the study were: 1. Explanation of the apparent temperature (AT) model; 2. Development of a modified apparent temperature (MAT) model; 3. Validation of the modified apparent temperature (MAT) model using physiological data from literature; 4. Evaluation of the modified apparent temperature (MAT) model by comparing it with the physiological heat transfer model (Goldman's model); 5. Simulation of the MAT model over the wide range of thermal conditions; 6. Performance of a sensitivity analysis of components in the MAT model; and 7. Simplification of the modified apparent temperature model (SAT). Results indicate that an apparent temperature model provides a valid representation of the physiological responses to a thermal environment. The MAT model can be simplified into a two-parameter SAT equation with a reasonably small loss in accuracy. This study supports the concept that AT is not only useful as an indicator of how a temperature feels, but it also meaningfully corresponds to changes in deep body temperature and thus potential heat stress. | |
