Financial liberalization and dynamics of firm-level financing and investment decisions in the Southeast Asian countries
… adjustments. This study also shows that non-linear estimation methods are more appropriate than linear estimation methods for capturing changes in capital structure. The empirical results also show that international stock market integration of these countries has significantly reduced the …

ΑΛΓΟΡΙΘΜΟΙ ΔΙΑΜΕΛΙΣΜΟΥ ΓΡΑΜΜΙΚΗΣ ΕΚΤΙΜΗΣΗΣ-ΣΥΓΚΡΙΤΙΚΗ ΥΠΟΛΟΓΙΣΤΙΚΗ ΑΝΑΛΥΣΗ
THIS THESIS IS DEALING WITH LINEAR ESTIMATION PARTITIONING ALGORITHMS, FOR DISCRETE TIME SYSTEMS. FOUR NEW RECURSIVE PER- SAMPLE PARTITIONING ESTIMATION ALGORITHMS ARE INITIALY PRESENTED, AND THE RELATED MERITS, WITH RESPECT TO THEIR COMPUTATIONAL REQUIREMENTS ARE EXAMINED AGAINST THREE OTHER …

Spatiotemporal brain imaging
… spatiotemporal neuroimaging method. I describe a linear estimation inverse approach, which is a method for the combination of functional magnetic resonance imaging (fMRI) with electroencephalography (EEG) and magnetoencephalography (MEG). fMRI provides millimeter spatial resolution, while EEG and …

From bits to information : learning meets compressive sensing
… dimensional data using the order statistics of linear and non linear measurements. We introduce new algorithms for signals classification in the multiclass and the multimodal settings, as well as algorithms for signals representation and recovery from quantized linear and quadratic measurements. …

Investments unwrapped : demystifying and automating technical analysis and hedge-fund strategies
In this thesis we use nonlinear and linear estimation techniques to model two common investment strategies: hedge funds and technical analysis. Our models provide transparent and low-cost alternatives to these two nontransparent, and in some cases prohibitively costly, financial approaches. In the …

Parameter Estimation for Delay Differential Equations: A New Galerkin Approximation Framework
… Within this Galerkin framework, the parameter estimation problem is reduced to the estimation of some scalar parameters in the resulting ordinary differential equations. Thanks to the analytical nature of the Galerkin approximation, the latter estimation problem can be handled efficiently, even …

The effect of oil price shocks on the macroeconomy
… and is well understood. Maximum likelihood estimation, which is commonly used for non-linear estimation, is used to estimate the model. We find in-sample evidence in favor of our new model for the 1986-2008 subsample. The new model is unable to provide better out-of-sample forecasts for the …

Interferometric Synthetic Aperture Microscopy
… the resulting algorithms demonstrate accurate linear estimation of the susceptibility of an object from the interferometric data. Using the regularized least squares solution, an ISAM reconstruction of underlying object structure having spatially invariant resolution is obtained from simulated …

Design and statistical analysis of fMRI experiments to assess human brain hemodynamic responses
… two experiments to assess the steady-state linearity of the hemodynamic system in prinwy visual cortex (Vl) for an event-related visual stimuli. In agreement with previous studies, we found that the system was approximately linear. Given this result, we used linear estimation techniques to …

A Model-Based Approach to Demodulation of Co-Channel MSK Signals
… is shown that MSK signals can be written in the linear model form, hence a minimum variance unbiased (MVU) estimator exists that satisfies the Cramer-Rao lower bound (CRLB) with equality. This framework allows us to derive the best estimators for a single-user and a two-user case. These concepts …

Design, Fabrication and Calibration of Compliant, Multi-Axis, Fiber-Optic Force/Torque Sensors for Biomechanical Measurements
… prototyped and successfully calibrated. A nonlinear Hammerstein-Weiner model (NLHW) was able to characterize the linear and nonlinear behaviour of this prototype. The optimized results have shown a reduction of over 40% in the Root Mean Square Errors (RMSE) in comparison with the linear …

3D sensing and mapping using mobile color and depth sensors

Symmetrical complementation designs
… in this design is presented in the chapter on linear estimation. The study shows that the number of contrasts that can be estimated is limited. For example, the usual linear contrast, which would lead to the hypothesis of equality of effects of all levels of one factor, is not testable in this …
