Respiration is the act of breathing, which is not possible without respiratory system. The respiratory system combines nose, throat, and lung. Lung 1 is the main organ, which performs the process of respiration. Airways ...

The present thesis deals with the study of direct and inverse problems for certain sumsets in additive number theory. Let A and B be two nonempty finite sets of integers. Let h and r be two positive integers. The first ...

This thesis investigates the role of spatial pattern formation in tumor{immune and predator{prey systems. In the rst half of the thesis, we have proposed spatiotemporal mathematical models using a system of non-linear ...

In this thesis, we study quasigroups with minimum number of associative triples. It is known the number of associative triples are connected to the security criteria of quasigroups based hash function. With the help of ...

In the practical world of everyday life, full of complexities, we face baffling problem of making the myriad of judgments. Every situation needs formulation of the problem under an appropriate theoretical model followed ...

Coding Theory deals with the construction and analysis of error-correcting codes for the reliable and efficient transmission of information through noisy channels. Since its inception, it has grown in to a large area, ...

In today's world the need and dependency of human being on mechanical system is increasing day by day. With the increasing demand, the advancement in the performance of mechanical system is one of the most important ...

The thesis reports a linear as well as weakly non-linear stability analysis of non-isothermal parallel flow in a vertical channel filled with porous medium. The flow is induced by external pressure gradient and buoyancy ...

Positivity of trigonometric sums has always been an important area of research because of its versatility of applications. The objective of the present thesis is to study the positivity of trigonometric polynomials for ...

In this thesis, we investigate and analyze a special class of Boolean functions namely bent functions. Using the existing techniques we derive the lower bounds of second-order nonlinearity and identify the a ne inequivalent ...
