Magneto hydrodynamic flow with viscous dissipation effects in the presence of suction and injection

Gyarmati's variational principle developed on the thermodynamic theory of irreversible pro-cesses is employed to study the viscous dissipation effects with uniform suction and injection on the infinite flat plate. The velocity and temperature fields inside the boundary layer are approximated as simple polynomial functions, and the functional of the variational principle is constructed. The Euler Lagrange equations are reduced to simple polynomial equations in terms of velocity and thermal boundary layer thicknesses. The velocity, temperature pro-files, skin friction and heat transfer with the viscous dissipation effects are analyzed and are compared with known numerical solutions. The comparison of the present solution with the existing solutions establishes the fact that the accuracy is remarkable

Changing Paradigms of Indian Foodtech Landscape - Impact of Online Food Delivery Aggregators

The purpose of this study is to depict the perception of consumers on the discount factor, future of food tech applications, tampering of family values, dine-out culture, technological anxiety and their impact on satisfaction behaviour. Millennials are the precedence audience for the online food aggregators. Generation X is different from other generations in perceiving discount factors. Future of food applications rely on the Discounts. Restaurant operators can focus on giving their customers an increased level of convenience and more discounts since these tend to be the reason for them to choose ordering food online. Optimisation is vital as increase in Technological anxiety increases the perceived future of food application and decreases the satisfaction behaviour
