The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and interacting with a many-body background.We discuss the impact of the impurities on the medium particles by considering feedback effects from polarons that can be realized in u
The outdoor ultra-high voltage (UHV) dry-type air-core smoothing reactors (DASR) of High Voltage Direct Current systems are equipped with a rain cover and an acoustic enclosure.To study the convective heat transfer between the DASR and the surrounding air, this paper presents a coupled model of the temperature and fluid field based on click here th
Climate change is a tricky issue.The Indian subcontinent has experienced many regional and local climatic changes in its past.There is overwhelming geological evidence of global climatic changes which are associated with extinctions and new life form adaptations.The Indian subcontinent is governed by monsoonal precipitation inextricably linked with
