Multivariate orthogonal polynomials
The object of this thesis is to define special orthogonal polynomials and develop efficient methods for employing them which have the same advantages with respect to functions of the type (1.2) as do univariate orthogonal polynomials in the simple case k=1. These new polynomials may be usefully …

Exact Solutions for Orthogonal and Non-Orthogonal Magnetohydrodynamic Stagnation-Point Flow
<p>The viscous plane flow of an electrically conducting fluid towards an infinite wall is solved in the presence of a magnetic field which is aligned with the flow far from the wall. The problem has two dimensionless parameters-- ε, the magnetic Prandtl number, and β, the square of the ratio of …

Orthogonal Generalized Frequency Division Multiplexing (OGFDM)
… technique of the transmission waveform termed as orthogonal generalized frequency division multiplexing (OGFDM) for increasing the wireless channel capacity without the need for extra bandwidth (BW) size or power consumption. The new wireless waveform (OGFDM) tends to obtain a better BW efficiency …

Orthogonal models for cross-classified observations
This thesis describes methods of constructing models for cross-classified categorical data. In particular we discuss the construction of a class of approximating models and the selection of the most suitable model in the class. Examples of application are used to illustrate the methodology. The …

Controlling Directions Orthogonal to a Classifier
… in tasks such as style transfer. While orthogonal decomposition is directly identifiable when the given classifier is linear, we formally define a notion of orthogonality in the non-linear case. We also provide a surprisingly simple method for constructing the orthogonal classifier (a …

Orthogonal parameters for two parameter distributions
Orthogonal parameters for a distribution, f(x,8<sub>i</sub>), (i=l,2,...,n), are defined such that E (- ∂² log f/∂β<sub>i</sub>∂β<sub>j</sub>=0 for all i, j, (i≠j). It has been pointed out that the problem of estimating the parameters of a distribution by maximum likelihood procedures, when the …

Spectrum-Aware Orthogonal Frequency Division Multiplexing
Reconfigurable computing architectures are well suited for the dynamic data flow processing requirements of software-defined radio. The software radio concept has quickly evolved to include spectrum sensing, awareness, and cognitive algorithms for machine learning resulting in the cognitive radio …

Vibration Suppression using Orthogonal Eigenstructure Control
A novel control method called orthogonal eigenstructure control is developed for active vibration cancellation in structures. Orthogonal eigenstructure control is a feedback control method applicable to multi-input multi-output linear systems. While the available control design methodologies offer …
