(2018-08-14)Ferroelectric ceramics are very promising materials for a variety of piezoelectric applications such as high permittivity dielectrics, piezoelectric sensors, piezoelectric/electrostrictive transducers, actuators, electro-optic ... -
Advanced Optimal Control Design for Nonlinear Systems including Impulsive Inputs with Applications to Automatic Cancer Treatment
(2018-08-14)The motivation of this research is to propose innovative nonlinear and optimal control design algorithms, which can be used in real life. The algorithms need to be computationally efficient, should deal with control ... -
Mechanical Characterization of Carbon Nanotubes and Nanocomposites
(2018-08-14)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) ... -
Structure and Dynamics of the Inter-tropical Convergence zones
(2018-08-13)The east-west oriented cloud bands in the tropics are called the Inter-tropical Con-vergence Zones (ITCZ). Till recently, the ITCZ has been assumed to have a simple vertical structure with convergence near the surface ... -
A Study of Two Problems in Nonlinear Dynamics Using the Method of Multiple Scales
(2018-08-13)This thesis deals with the study of two problems in the area of nonlinear dynamics using the method of multiple scales. Accordingly, it consists of two parts. In the first part of the thesis, we explore the asymptotic ... -
Experimental Study of Patterns in Hydrodynamically Deposited Dispersed Phase of CaCO3 on Surfaces of Straight Cylindrica Silica Tubing
(2018-08-13)Deposition of dispersed phase from flowing dispersions onto a substrate surface is of utmost relevance for various industrial processes like fouling of sparingly soluble salts, such as CaCO3 and CaSO4 in heat exchangers and ... -
Evolutionary Aspects of Archean Kolli-Massif, Southern India : An Archive of Crustal Processes
(2018-08-13)The continental crust is the record of the history of the Earth, of the processes and events that have contributed to the planet's evolution. It is now understood that the continental crust is growing continuously since ... -
Modelling Simulation and Statistical Studies of Primary Fragmentation of Coal Particles Subjected to Detonation Wave
(2018-08-11)Coal is likely to remain an important energy source for the next several hundred years and hence advances in coal combustion technologies have major practical impact. Detonation combustion of coal initiated by a plasma ... -
On the Factors Influencing the Stability of Phases in the Multiferroic System BiFeO3-PbTiO3
(2018-08-11)Rhombohedral perovskite BiFeO3 is a single phase multiferroic compound exhibiting both magnetic (Neel temperature ~370˚C) and ferroelectric (Curie point ~840˚C) ordering well above the room temperature. Ferroelectricity ... -
