Thermal conductivity common use in the construction and textile industries. The construction industry makes use of units such as the R-value (resistance) and the U-value (transmittance). Although related to the thermal conductivity of a material used in an insulation product, R- and U-values are dependent on the thickness of the product. Likewise the textile industry has several units including the tog and the clo which express thermal resistance of a material in a way analogous to the R-values used in the construction industry. There are a number of ways to measure thermal conductivity. Each of these is suitable for a limited range
Synthetic measure Synthetic measure A synthetic measure (or synthetic indicator) is a value that is the result of combining other metrics, which are measurements of various features. There is a method to measure quality of service in hotels. In related study authors aggregate tourist opinions, measured on a scale from 1 to 10. Synthetic measure (indicator) of service quality in each hotel is calculated with the help of the aggregation operator. Other study proposed to use classical parameters EV, PV and AC to carry out the synthetic measure of project performance. Different normalized stimulants and destimulants were used in research to create
