Public Expenditure, Environmental Pollution And Endogenous Economic Growth., Trishita Ray Barman Dr.
Doctoral Theses
Sources of Economic Growth and the Definition of Steady-State EquilibriumEconomic growth is defined as a continuous increase in national income taking place over a time horizon. According to the neoclassical theory of economic growth there are three sources of economic growth: (i) capital accumulation, (ii) growth of labour force and (iii) technological progress.The steady-state growth equilibrium is defined as a state where all major macro-economic variables grow at the same rate so that the ratios of these variables remain unchanged over time. For example, in the one sector aggregative model like that of Solow (1956), capital and labour grow at …
Enhancing Effective Depth-Of-Field By Multi-Focus Image Fusion Using Morphological Techniques., Ishita De Ghosh Dr.
Enhancing Effective Depth-Of-Field By Multi-Focus Image Fusion Using Morphological Techniques., Ishita De Ghosh Dr.
Doctoral Theses
A scene to be photographed, usually includes objects at varying distances from the camera. Depth-of-field of a digital camera is the range of distance, all objects within which appear to be sharp in the image. Due to the low depth-of-field of the camera, images acquired by them often suffer from degradation called out-of-foc us blur. One way to enhance the effective depth-of-field is to acquire se veral images of a scene with focus on different parts of it and then combine these images into a single image in such a way that all regions of the scene are in focus. …

Essays On Regular Variations In Classical And Free Setup: Randomaly Weighted Sums, Products In Cevm And Free Subexponentiality., Rajat Subhra Hazra Dr.
Doctoral Theses
In this thesis, we shall be focusing on some problems in probability theory involving regularly varying functions. The theory of regular variations has played an important role in probability theory, harmonic analysis, number theory, complex analysis and many more areas of mathematics. For an encyclopedic treatment of the subject, we refer to Bingham et al. (1987). In probability theory, the limiting behavior of the sums of independent and identically distributed (i.i.d.) random variables is closely related to regular variation. The books by Feller (1971) and Gnedenko and Kolmogorov (1968) give characterizations of random variables in the domains of attraction of …
Essays In The Economics Of Environmental Policy., Ashokankur Datta Dr.
Essays In The Economics Of Environmental Policy., Ashokankur Datta Dr.
Doctoral Theses
It is increasingly being accepted that the planet we live in is unable to fulfill the enormous resource demands that mankind places on it. As a result the environment we live in has undergone rapid changes in the last two centuries - changes that adversely affects human life. Long ago Thomas Malthus and more recently the Club of Rome researchers warned that rapid economic and population growth were going to be unsustainable as they are going to create an acute shortage of food and vital metals like mercury. Their predictions never passed the test of time (Sterner, 2003). However their …
Some Results On Cryptanalysis Of Rsa And Factorization., Santanu Sarkar Dr.
Some Results On Cryptanalysis Of Rsa And Factorization., Santanu Sarkar Dr.
Doctoral Theses
In this thesis, we propose some new results in Cryptanalysis of RSA and related Factorization problems. Till date, the best known algorithm to solve the Integer Factorization problem is the Number Field Sieve, which has a runtime greater than exp(log1/3 N) for factoring an integer N. However, if one obtains certain information about the RSA parameters, there are algorithms which can factor the RSA modulus N = pq quite efficiently. The intention of this thesis is to identify such weaknesses of the RSA cryptosystem and its variants. Further we study results related to factorization.In Africacrypt 2008, Nitaj presented a class …
Some Aspects Of Toric Topology., Soumen Sarkar Dr.
Some Aspects Of Toric Topology., Soumen Sarkar Dr.
Doctoral Theses
The main goal of this thesis is to study the topology of torus actions on manifolds and orbifolds. In algebraic geometry actions of the torus (C * ) n on algebraic varieties with nice properties produce bridges between geometry and combinatorics see [Dan78], [Oda88] and [Ful93]. We see a similar bridge called moment map for Hamiltonian action of compact torus on symplectic manifolds see [Aud91] and [Gui94]. In particular whenever the manifold is compact the image of moment map is a simple polytope, the orbit space of the action. A topological counterpart called quasitoric manifolds, a class of topological manifolds …
