Geometric Asian option: Geometric Ornstein-Uhlenbeck process
… assumption that the underlying asset follows a geometric Brownian motion. This dissertation, however, assumes that the underlying asset follows a geometric Ornstein-Uhlenbeck process and provides an explicit formula for the geometric Asian options. The geometric Ornstein-Uhlenbeck process is …

Geometric electroelasticity
In this work a diffential geometric formulation of the theory of electroelasticity is developed which also includes thermal and magnetic influences. We study the motion of bodies consisting of an elastic material that are deformed by the influence of mechanical forces, heat and an external …

Geometric Probing
We consider problems in geometric probing, the algorithmic study of determining a geometric structure or some aspect of that structure from the results of a mathematical or physical measuring device. A variety of problems from robotics, medical instrumentation, mathematical optimization, integral …

Geometric Dimensionality Reduction
… disciplines. In this thesis we establish Geometric Dimensionality Reduction, a non-linear data compression technique that utilizes low dimensional manifolds embedded in dimensional spaces to form composite contraction-and-projection maps. Geometric Dimensionality Reduction is predominantly …

Fast geometric algorithms
… add to the present database of fast adaptive geometric algorithms. What emerges is a collection of techniques that is successful at merging modern tools developed in analysis of algorithms with those of classical geometry.

Geometric Fuzzy Logic Systems
… the novel approach ofdefining fuzzy sets as geometric objects - geometric fuzzy sets. The logical operations for geometric fuzzy sets are defined as geometric manipulations of these sets. This novel geometric approach is applied to type-I, type-2 interval and generalised type-2 fuzzy sets and …

Geometric Multimedia Time Series
… in this application, an incredibly simple geometric descriptor based on self-similarity matrices performs the best, and it also enables us to use MFCC features for this task, which was previously thought not to be possible due to significant timbral differences that can exist between …

Stability in Geometric Theories
The second question is answered for o-minimal structures that eliminate imaginaries. It is proved that for any structure D whose theory is o-minimal and eliminates imaginaries, any stable group interpretable in D is totally transcendental with finite Morley rank. A strengthening of Buechler's …

Geometric Functional Data Analysis
… precludes studies aimed at understanding how geometric variations relate to functional variations. On the other hand, functional data analysis has mostly developed tools for simplified settings, such as one-dimensional functional samples, limiting their applicability to real data. We formulate …

Geometric and Extra-Geometric Spatial Conceptualisation: A cross-linguistic and non-verbal perspective
… all past empirical work exploring the Functional Geometric Framework (FGF) proposed by Coventry and Garrod (2004) for spatial language use has been based on a single language - English. Therefore the extent to which the framework applies across languages has not been established. The current …

Stochastic Geometric Mechanics and Symmetry
We explore the interaction between geometry, symmetry, and randomness in stochastically perturbed mechanical systems, in Hamiltonian as well as Lagrangian (variational) formulations. On the Hamiltonian side, we discuss a stochastic Kepler problem with a noisy angular momentum vector. We show that …

Lapithos: the Upper Geometric Cemetery
<p>This study focuses on Cypro-Geometric Lapithos, situated on the north coast of Cyprus. Its purpose is to study the excavations and unpublished material from the UpperGeometric cemetery, excavated in 1931-32, and to explore the topography of Early IronAge Lapithos and of the north coast. The …

Geometric Theory of Parshin Residues
… in the complex case one would expect a more geometric variant of the theory. In my thesis I study Parshin residues from the geometric point of view. In particular, the residue is expressed in terms of the integral over a smooth cycle. Parshin-Lomadze Reciprocity Law for residues in the …

Geometric Control of Ensemble Systems
Robust and sensorless manipulation of large populations of dynamical systems is prevalent in numerous research areas of science and engineering. Prominent examples range from excitations of spin ensembles in nuclear magnetic resonance (NMR) spectroscopy and imaging (MRI), and desynchronization of …

Compass routing on geometric graphs.
… to find paths between pairs of points in planar geometric graphs. Our main goal was that of developing, whenever possible, routing algorithms that, using only "local information", the position of our destination and a finite amount of extra memory, find a path from a starting position to our …
