Infinite Derivative Gravity : a finite number of predictions
Ghost-free Infinite Derivative Gravity (IDG) is a modifed gravity theory which can avoid the singularities predicted by General Relativity. This thesis examines the effect of IDG on four areas of importance for theoretical cosmologists and experimentalists. First, the gravitational potential …

Dynamics and Measures for Semigroups of Rational Functions
… where the Fatou set contains an arbitrary finite number of components. The Fatou set of a single rational function must contain zero, one, two or infinitely many components.

Power Integral Points on Elliptic Curves
… power. This is done by consideration of the finite number of rational and irrational newforms corresponding to an also finite number of levels of these newforms: in thirty cases we give a bound via examination of both the rational and irrational cases, and for the remaining forty-two cases …

A genetic algorithm applied to the fractal inverse problem
… one to construct a fractal which depends on a finite number of parameters. The associated inverse problem, finding a set of parameters which reconstructs a given fractal, is much more difficult. This paper explores the possibility of solving the inverse program with the genetic algorithm.

Communication for wideband fading channels : on theory and practice
… for a Rician channel is discrete with a finite number of mass points in the low SNR regime. A similar discrete structure for the optimal amplitude is proven to hold over the entire SNR range for the average power limited Rayleigh block fading channel. Channels with a peak power constraint …

Modeling and Control of Multiphase DC -Dc Converters With Linkages to Hybrid Control
… the state between two valid limit cycles in a finite amount of time, with a finite number of switch transitions. Sufficient but conservative algebraic conditions for deadbeat controllability of piecewise linear hybrid systems with finite state-vector dimension are presented.

A repairable item inventory system using dynamic programming and Markov processes
… stocked ready-for-issue units in support of a finite number of customers. A least-cost repair policy and stock level was determined by use of a computer program which is included as an appendix.

The reflection method in the bending of beams and plates
… considering the plate to be a portion of an infinite plate, ignoring the prescribed boundary conditions. The known loads are then applied to the infinite plate and their effects are calculated at those points which correspond to the boundary of the original plate. A system of suitably chosen …

Logspline Density Estimation with an Application to the Study of Survival Data of Lung Cancer Patients.
… from a space of linear splines that have a finite number of fixed uniform knots. In the end of this thesis, the method is applied to a real survival data set of lung cancer patients.</p>

A method for the calculation of excitonic effects in certain metals
… into the calculation by randomly choosing a finite number of electrons to represent the hole and calculating the response of these chosen electrons to the excited electron. Calculations were done for lithium, sodium, potassium, calcium and aluminum.

On the Use of Quasi-Newton Methods for the Minimization of Convex Quadratic Splines
… conditions. In this work, the positive definite secant update method of Broyden, Fletcher, Goldfarb, and Shanno (BFGS) is investigated as a tool to solve the unconstrained minimization problem. It is shown that there is a linear convergence rate and, for nondegenerate problems, the process …

Rateless and rateless unequal error protection codes for Gaussian channels
… cannot be prioritized. In addition, if only a finite number of retransmissions is allowed, the range of available rates that a rateless code can provide is limited. In contrast, a UEP code provides a prioritization of the bitstream, and an arbitrary range of rates but does not achieve capacity. …

Uma formalização da mecânica analítica dos sistemas de corpos rígidos
… without the preliminary study of systems with a finite number of parti eles. ln doing so, the role of the evolution law for the angular momentum is made clear for the development of the theory. We obtain Euler's equation for a rigid body with a fixed point from Lagrange's equations, without using …

Two Aspects of Topology in Graph Configuration Spaces
… space is generated by the movement of a finite number of robots on a graph. These configuration spaces of points in a graph are topologically interesting objects. By using local, combinatorial properties, we define a new classification of graphs whose configuration spaces are …

Towards DIVE : A platform for automatic visualization and analysis of structured datasets
… data. Conceptually, for any dataset, there are a finite number of combinations of its elements. Therefore there are a finite number of common visualizations or analyses of a dataset. In other words, it should be possible to enumerate the whole space of possible visualizations and analyses for a …

Hecke Correspondence for Automorphic Integrals with Infinite Log-Polynomial Periods
… and automorphic forms, there have been a great number of generalizations. Of particular interest is a generalization due to Bochner that gives a correspondence between Dirichlet series with any finite number of poles that satisfy the classical functional equation and automorphic integrals with …
