The generation of noise by the fluctuations in gas temperature into a turbine [PDF]
, 1974 An actuator disc analysis is used to calculate the pressure fluctuations produced by the convection of temperature fluctuations (entropy waves) into one or more rows of blades. The perturbations in pressure and temperature must be small, but the mean

Second‐Order Between‐Supplier Learning
Journal of Operations Management, EarlyView.ABSTRACT Substantial empirical evidence shows that suppliers in emerging economies can enhance their technological capabilities through direct learning from technologically advanced foreign competitors. However, suppliers in emerging markets may struggle to learn directly from knowledge about competitors’ products that are not widely available on the ...
