A techno-economic rating system for highways using discrete multi-criteria analysis

    In developing countries, like Bangladesh, priority to upgrade a national highway is mainly based on technical aspects like daily traffic demands; whereas due consideration to economic factors is generally neglected. Based on a few parameters, if highways are rated keeping in mind some social economic attributes, significant contribution to our infrastructure-based economy could be made....

Magneto–thermo-viscoelastic material with a spherical cavity

  The present paper is concerned with a homogeneous isotropic perfect conducting viscoelastic body with a spherical cavity subjected to both ramp-type heating and external constant magnetic field. The model of the equations in the context of generalized thermoelasticity with one relaxation time is introduced. The closed form solution for distributions of displacement; temperature, strain, and stress are...
