Effect of cross wind on aerodynamic coefficients of ground vehicles. [PDF]
, 2009 The present work investigates the variation of aerodynamic coefficients with the change in the angle of flow. A mathematical equation has been developed for predicting the aerodynamic coefficients, when a vehicle is subjected to crosswind.

Penalizing cartels : the case for basing penalties on price overcharge [PDF]
, 2014 In this paper we set out the welfare economics based case for imposing cartel penalties on the cartel overcharge rather than on the more conventional bases of revenue or profits (illegal gains).
