In-car comfort functions decrease driving stress and therefore increase safety. Drivers typically do not use all available comfort functions optimally, if at all, in every situation they would offer a substantial increase in comfort. Automating such functions as proactive recommender systems would exploit the full potential for decreasing driver stress. Because comfort functions are highly depe...

Subjective wear trials have been carried out to determine thermal comfort performance of knitted sports garments whose objective thermal comfort parameters are determined in a preceding study in fabric form. Physiological measurements (skin and microclimate temperature, microclimate relative humidity, heart rate and sweat amount) and psychological rating results (coolness, dampness and comfort)...

This paper focused on the comfort afforded by 3 models of hearing protection devices. Devices were selected and, after being tested in a real occupational context, evaluated using a questionnaire regarding different comfort indexes. In this way, it was possible to compare the “performance” of the hearing protectors regarding the comfort indexes, and to determine which one, globally, has afforde...

Outdoor spaces are important to sustainable cities because they accommodate pedestrian traffic and outdoor activities, and contribute greatly to urban livability and vitality. In the global context of climate change, outdoor spaces that provide a pleasurable thermal comfort experience for pedestrians effectively improve the quality of urban living. The influence of thermal comfort on outdoor ac...

Subjective thermal comfort plays a critical role in body temperature regulation since this represents the primary stimulus for behavioral thermoregulation. Although both core (Tc) and skin-surface (Tsk) temperatures are known afferent inputs to the thermoregulatory system, the relative contributions of Tc and Tsk to thermal comfort are unknown. We independently altered Tc and Tsk in human subje...

The present work is focused on the control of indoor thermal comfort in buildings equipped with HVAC (Heating, Ventilation and Air Conditioning) systems. The occupants’ thermal comfort sensation is addressed here by the well-known comfort index (PMV Predicted Mean Vote). In this context, different strategies for the control algorithms are proposed by using only-one-actuator system that can be a...

This document describes a visual comfort calculation developed by the LESO group at EPFL during Spring of 1991. The calculation uses the RADIANCE synthetic imaging system [Ward90] to compute luminance values from a computer model of an architectural space and the lighting and daylighting of that space. These luminance values are then applied to a selected glare calculation procedure to arrive a...

1 The first section of a three-part article on Compstat, an information-driven managerial process, examines four crime-reduction principles that form the basis of the technique. Agencies must ensure that they are prepared to handle situations involving officers in crisis. 26 Eight Supreme Court decisions of particular importance to law enforcement are summarized. Contributors' opinions and stat...

Twenty-three females between the ages of 19 and 35 were studied in order to compare the effects of variations in pulse duration, waveform symmetry, and source regulation on comfort during quadriceps surface stimulation at amplitudes necessary to produce 27 Nm torque. Stimulation parameters compared were: 1) 50 and 300 microseconds pulse durations, 2) asymmetrical and symmetrical biphasic wavefo...
