The dual space of V, denoted by V *, is the vector space of all linear functionals on V, i.e., V * = ℒ ( V, 𝔽). When dealing with linear functionals, it is convenient to follow Paul Dirac (1902--1984) and use his bra-ket notation (established in 1939). In quantum mechanics, a vector v is written in abstract ket form as | v >.
ISO 7243:2017 presents a screening method for evaluating the heat stress to which a person is exposed and for establishing the presence or absence of heat stress. It applies to the evaluation of the effect of heat on a person during his or her total exposure over the working day (up to 8 h). It does not apply for very short exposures to heat.
Résumé. Le présent document expose des méthodes et des stratégies ayant pour but d'évaluer la contrainte thermique associée à l'exposition aux environnements froids. Ces méthodes s'appliquent aux expositions et aux types de travaux continus, intermittents et occasionnels, aussi bien en intérieur qu'à l'extérieur.
the annual energy use for heating and cooling of the building, using input from the relevant system standards referred to in ISO 13790:2008 and specified in Annex A. ISO 13790:2008 also gives an alternative simple hourly method, using hourly user schedules (such as temperature set-points, ventilation modes or operation schedules of movable

The indentation hardness of flexible cellular materials is a measure of their load-bearing properties. ISO 2439:2008 specifies four methods (A to D) for the determination of indentation hardness and one method (E) for determination of compressive deflection coefficient and hysteresis loss rate of flexible cellular materials.
ISO 4048:2008 specifies a method for the determination of the substances in leather which are soluble in dichloromethane. This method is applicable to all types of leatherISO 4048:2008 includes two techniques for extraction of the fatty substances: 1) extraction using the Soxhlet apparatus; and 2) extraction using a pressurized extraction system.
