The present paper presents an analytical study of the one-dimensional weak shock wave problem in a perfect gas under action generalized magnetic field subjected to jump conditions (R-H conditions). is considered axial and azimuthal cylindrically symmetric configuration. By considering straightforward approach, explicit solution exhibiting time-space dependency for gas-dynamical flow parameters ...

The study of rotary steering drilling technology is currently one of the hot topics in the drilling engineering field. It requires accurate well trajectory control instructions when rotary steerable tools are applied to achieve the well trajectory control goal. A drilling trajectory prediction model will benefit this progress. According to the continuous beam theory, a mechanical model of push-...

Following a recession, the aggregate labor market is slack–employment remains below normal and recruiting efforts of employers, as measured by help-wanted advertising and vacancies, are low. A model of matching friction explains the qualitative responses of the labor market to adverse shocks, but requires implausibly large shocks to account for the magnitude of observed fluctuations. The incorp...

We consider the effect of money illusion defined referring to Stevens' ratio estimation function on the long-run Phillips curve in an otherwise standard New Keynesian model of sticky wages. We show that if households under-perceive real economic variables, negative money non-superneutralities will become more severe. On the contrary, if households over-perceive real variables, positive money no...
