1. EXPLORING THE APPLICATION OF NUMBER THEORY IN CRYPTOGRAPHY

69 Student Researchers

Background of the study

Cryptography has a long and intricate history that intertwines with the development of number theory. From the ancient ciphers of Julius Caesar to the complex algorithms used in modern-day encryption, the evolution of cryptographic methods has been driven by the need to secure information in an increasingly digital world. Central to this evolution has been the application of number theory, a branch of pure mathematics that de...

5. RESULTS ON INVARIANT WHISKERED TORI FOR FIBERED HOLOMORPHIC MAPS AND ON COMPENSATED DOMAINS.

69 Student Researchers

ABSTRACT

This thesis is composed of two independent papers: Construction of whiskered invariant tori for fibered holomorphic maps In this paper we present a very general theory that includes results on the persistence of quasi-periodic orbits of systems subject to quasi-periodic perturbations. Such quasi-periodic systems appear naturally in many applications where systems are subject to external perturbations of quasi-periodic nature. This is joint work with Rafael de la Llave. The...

6. DETERMINATION OF THE NUMBER OF NON-ABELIAN ISOMORPHIC TYPES OF CERTAIN FINITE GROUPS

69 Student Researchers

Abstract

The first part of this work established, with examples, the fact that there are more than one non-abelian isomorphic types of groups of order n = sp, (s,p) = 1, where s

1 was worked out and such groups have no non-abelian isomorphic types. This gave credence to the fact that a group of order 15 and its like do not have a non-abelian isomorphic type. It also generated the non-abelian isomorphic types of groups of order n = spq, where s, p and q are distinct primes...

7. COMBINATORIAL PROPERTIES OF THE ALTERNATING & DIHEDRAL GROUPS AND HOMOMORPHIC IMAGES OF FIBONACCI GROUPS

69 Student Researchers

Abstract

Let Xn = { } 1,2,…,n be a finite n -element set and let Sn An and Dn , be the Symmetric, Alternating and Dihedral groups of Xn , respectively. In this thesis we obtained and discussed formulae for the number of even and odd permutations (of an n − element set) having exactly k fixed points in the alternating group and the generating functions for the fixed points. Further, we give two different proofs of the number of even and odd permutations (of an n −...

8. ONE-STEP SECOND DERIVATIVE BLOCK INTRA-STEP POINTS FOR STIFF SYSTEMS OF INITIAL VALUE PROBLEMS

69 Student Researchers

ABSTRACT Modified class of single-step numerical schemes were proposed to improve the order of accuracy by imposing intra-step points in the formulation process of the proposed algorithms. The behaviour of modified numerical algorithm is of great concern when varieties of countable off-grid points are imposed within the grid points in the derivation process. In this study, we present a one-step second derivative modified algorithms for numerical solution of first order initial value problems...

9. MODELING THE TOPOLOGICAL RELATIONSHIP OF SPATIAL OBJECTS USING EGENHOFER MATRICES

69 Student Researchers

ABSTRACT

The analytical needs in geographic information systems (GIS) have led to the interpretation of formal methods of modeling the topological relationship of spatial objects using Egenhofer-matrices. As a result, we investigate the algebraic approach for the structural analysis of a spatial topology- Simplices, The Order of Simplices, Faces of Simplices, Simplicial Complex, Skeletons of Simplicial Complex. Oriented Simplex, Connectedness of Spatial Objects. The matrix interpret...

10. MATHEMATICAL MODELLING FOR ANALYSING FIRE SPREAD IN A REAL-TIME COUPLED ATMOSPHERIC WILDLAND FIRE

69 Student Researchers

ABSTRACT

Wildland fire spread is one of the most challenging problems faced by reserved or unreserved vegetation in many developed and developing nations, because it can lead to serious environmental hazards in claiming lives, properties, animals and some other valuable treasures. This thesis establishes an approximate analytical solution that is capable of analysing fire spread in a real-time coupled atmospheric wildland fire, in determining the effect of temperature, oxygen concen...

69 Student Researchers

ABSTRACT

This thesis investigated the effect of temperature dependent thermal conductivity and diffusion coefficient on the filtration combustion in a wet porous medium. The model which relies on several assumptions and based on the conservation of total mass, chemical species and energy written in transient state mode of operation which governed the phenomenon is presented. The existence of unique solution of the problem was examined by actual solution method. The properties of sol...

ABSTRACT

This research focuses on the formulation of block hybrid methods with power series as basic function through interpolation and collocation techniques for numerical solution of second order initial value problems in ordinary differential equations. The step number for the derived block hybrid method is k=2 with two off-step point and four offstep points. The basic properties of numerical methods were analyzed and findings revealed that the methods were consistent, zero-stabl...
