This thesis proposes a multi-physics model to couple the electrical, mechanical, thermal and quantum mechanical interactions in semiconductor and their heterostructures. Governing differential equations and constitutive ...

Nonlinear trajectory optimization based optimal guidance schemes are presented in this thesis for soft-landing of spacecrafts on atmosphere-less celestial bodies. First, a pseudo-spectral philosophy based multi-phase ...

Constraints in input, output, and states are evident in most of the practical systems. Explicitly incorporating these constraints into the control design process leads to its superior performance in general. Therefore, ...

The modern-day axial compressor stages in a gas turbine engine play a vital role in generating the high-pressure ratios by operating at the limits of their design. Aerodynamic instabilities such as rotating stall and surge ...

The thesis touches numerical solutions and wave propagation analysis using spectral methods for different classes of partial differential equations (PDEs) having applications in various fields. We address the solution of ...

This thesis deals with the design and development of a 75 mm fixed-wing nano-air vehicle (NAV). The NAV is designed to fit inside a cube with each side measuring 75 mm. The range and endurance of the NAV are 300 m and 2-3 ...

This thesis deals with computing the pressure distribution around a swimming slender fish and the thrust generated by its flapping motion. The body of the fish is modeled as a missile like slender body to which a tail is ...

Autonomous vehicles perform time and cost effective operations with minimal or no human effort and hence, have the potential to be used in civilian, commercial and military applications. Pertaining to these applications, ...

Composites are materials which cater to the present and future needs of many demanding industries, such as aerospace, as they are weight-sensitive for a given requirement of strength and stiff ness, corrosion resistant, ...

Measurement of all the mechanical properties of carbon nanotubes is extremely difficult because of its small size. In the present work, all the five transverse isotropic properties of single wall carbon nanotubes (SWCNTs) ...
