Force attenuation capacity and thermophysiological wear comfort of vertically lapped nonwoven fabric

An evaluation of force attenuation, comfort properties and density of materials for hip protective pads

“…The rank orders derived using the Robinovitch approach and Equation (6) are not identical, but are highly correlated (Pearson's r = 0.80). Note that using Robinovitch's approach, pad G has the lowest rank, but according to Equation (18), pad B has the lowest rank. This is because the impact force on pad B was higher than 2.5 kN, so it would not protect an elderly woman's hip bone from a fall impact.…”

“…The data were then transferred to a computer using Bluetooth. 18 According to Robinovitch et al, 13 typical speeds of person fall are 2.0 m/s for a mild fall, 3.4 m/s for a moderate fall and 4.5 m/s for a severe fall. The kinematic equation for free fall is illustrated in the following…”

“…Knitted fabric of 30 × 30 cm was used as a fabric layer, with a pocket of 21 × 21 cm sewn in its middle. The pad was inserted into the pocket 18 (Figure 2).…”

Analysis of the Influence Subjective Human Parameters in the Calculation of Thermal Comfort and Energy Consumption of Buildings

“…Some recent examples of the application of comfort analysis concepts in singular environments include a synagogue design [16], strategies for low-cost housing [17], the evaluation of a modern low-energy office [18] or materials for hip-protective pads [19]. Thermal comfort is thus one of the most important elements in the relationship with the estimation of indoor environment quality, and it has been defined in parallel by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) Standard 55 and ISO (International Standard Organization) Standard 7730 as "the condition of the mind in which satisfaction is expressed with the thermal environment" [20,21].…”

Desarrollo de modelos matemáticos y análisis de sensibilidad para el estudio energético de edificaciones.

“…Una búsqueda rápida en bases de datos científicas muestra que la comodidad en los edificios es una temática de interés en campos de investigación muy diferentes como Ingeniería (39 %), Energía (14 %), Ambiental (10 %), Informática (7.5 %) y Ciencias Sociales (7 %), en menor medida, se encuentra en ciencia de la salud, la tierra y economía. Algunos ejemplos de análisis del confort térmico son el diseño de una sinagoga [47], estrategias para viviendas de bajo costo [48], materiales para almohadillas protectoras de la cadera [49] y evaluación en oficinas modernas de bajo consumo de energía [50].…”
