In this paper, a new technique is being proposed to estimate the PMV by using an array of sensors for the automatic control of thermal sensation scale of the air conditioning system. The predicted mean vote (PMV) is a well recognized thermal comfort index and is used for measuring comfort level inside the conditioned space. It is a mathematical function dependent on air temperature, relative hu...

Higher education institutions (HEI) are the centre of learning and teaching that responsible for producing high-quality first-generation. The inadequate number student accommodations also resulted in stacking several students one room, leading to discomfort, space constraints, lack privacy, other health conditions. This study investigates level indoor thermal comfort on occupant living at resid...

BACKGROUND Fanger's PMV equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, relative air velocity, humidity, activity level and clothing insulation. METHODS This paper contains a comparison of suit dresses and summer clothes in terms of thermal comfort, Fanger's PMV equation. Studies were processed in the winter for an office, which lo...

A large number of independent and interacting factors affect seating comfort such as seat shape, stability, lumbar support and seat height. Although many subjective comfort studies have been conducted, few of them considered seating comfort from its subassembly level. This paper analyzed the automotive seat cushion designed with geared four-bar linkage for the seat height adjustment. The operat...

PURPOSE To examine the phenomenon of comfort in the context of childbirth. Enhancement of comfort for laboring women is a valued outcome of nursing and midwifery care. Interventions that increase comfort during labor support a woman's effort to participate more fully in the birth thereby keeping her more aware of her body, emotions, and experience. ORGANIZING CONSTRUCT The concept of comfort ...

Numerical simulations can be used to evaluate the comfort index at the railway vehicles. To this purpose, a complex model of the vehicle-track system is used that takes into account a string of factors influencing the level of the vertical vibrations, thus allowing a correct evaluation of the dynamic behaviour in the railway vehicles, mainly at high velocities. The influence of the vertical sus...

Background: Today, the effects of environmental pollution on human life and human needs, which reduces the level of community health caused by traffic noise in large cities, are clearly visible by creating irritation and pathogenic conditions. The aim of this study was to assess the risk of noise pollution resulted from central traffic in Shiraz by analyzing its indicators and related componen...

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...

OBJECTIVES The level of expertise and degree of training in neonatal resuscitation (NNR) of emergency physicians is not standardized and has not been measured. We sought to determine the self-reported comfort with, knowledge of, and experience with NNR of emergency department (ED) staff in a general ED prior to the opening of a new neonatal intensive care unit (NICU) and to explore factors asso...
