Modified mathematical model for variable fill fluid coupling

Variable fill fluid couplings are used in the speed control units. Also, variation in coupling oil volume is used in adapting one size of coupling to a wider range of power transmission applications. Available model for the partially filled fluid couplings, has a good performance for couplings with fixed amount of oil but their performance will be degraded if they are used for the variable fill...

Industrial quality : a missing economic variable

Industrial quality is presented as a direct result of manufacturing practices (e.g. tolerance allocation, process selection, inspection procedures). A quality indicator is developed that allows for the computation of a function representing the cost of an industrial product versus its quality level. This cost function is then incorporated in an economic model that estimates the consumer's deman...

Missing bits of the solar jigsaw puzzle: small-scale, kinetic effects in coronal studies

The solar corona, anomalously hot outer atmosphere of the Sun, is traditionally described by magnetohydrodynamic, fluid-like approach. Here we review some recent developments when, instead, a full kinetic description is used. It is shown that some of the main unsolved problems of solar physics, such as coronal heating and solar flare particle acceleration can be viewed in a new light when the s...
