Source characterization using linear transformations of multichannel biomagnetic recordings
… present thesis demonstrate the potential of the linear transformations to generate data representations that enable straightforward and effective extraction and characterization of the biomagnetic signal components, and the elimination of the interference. The independent component analysis has …

Asymptotic formulae for certain arithmetic functions produced by fractional linear transformations
… functions defined in terms of fractional linear transformations arising from certain $2 \times 2$ matrices, establish asymptotic formulae for averages of these functions, and explore certain maps that arise from considering the leading terms of these averages. We further generalize to a …

Extensions of the Cayley-Hamilton Theorem with Applications to Elliptic Operators and Frames.
… Theorem is an important result in the study of linear transformations over finite dimensional vector spaces. In this thesis, we show that the Cayley-Hamilton Theorem can be extended to self-adjoint trace-class operators and to closed self-adjoint operators with trace-class resolvent over a …

Álgebra linear: uma aplicação à Genética.
This work aims to show the importance of Linear Algebra and its private applications, in the occupation area of genetics, as well as expose of practical way the interdisciplinarity that pervades between the curriculum components. We present a brief history of the rise of linear algebra as well as a …

Geometry Of Quivers
… representations consist of vector spaces and linear transformations. We explore some the connections between quivers and geometric structures. To begin, we consider a theorem that says every projective variety can be considered as a quiver Grassmannian. The reasoning of the proof is …

Second-order finite free probability
… study the behaviour of the eigenvalues of random linear transformations under addition. Finite free probability seeks in particular to characterize random matrices in terms of their (random) characteristic polynomials. I studied the covariance between the coefficients of these polynomials, in …

Spiral architecture for machine vision
… ring is employed to generate an algebra of linear transformations which are appropriate for the processing of multidimensional vision data. A parallel autonomous segmentation algorithm for multidimensional vision data is described. The algebra and segmentation algorithm are implemented on a …

The effect of students' physics background on their understanding of linear algebra
Concepts of vectors, linear combinations and spanning, transformations and linear transformations in the teaching of Linear Algebra, a geometric approach was taken. Activities in the aforementioned areas were designed in a dynamic computer environment Cabri Geometry II that allowed students to …

Multiview feature learning for speech recognition
… this thesis, we study the problem of learning a linear transformation of acoustic feature vectors for speech recognition, in a framework where apart from the acoustics, additional views are available at training time. We consider a multiview learning approach based on canonical correlation …

Involutory matrices, modulo m
… (mod P<sup>α</sup>) of order n are considered as linear transformations on a vector space of n-tuples to provide uncomplicated proofs for the basic results concerning involutory matrices over a finite field.

Nonlinear transform coding with lossless polar coordinates
… prevents one from considering the use of a nonlinear change of variables. If no linear transformation of a given source would yield independent components, this means having to encode it at a rate higher than its entropy, i.e. suboptimally. This thesis proposes a new transform coding technique …

Comparing learned representations of deep neural networks
… in a high dimensional space and applying a linear classifier in this space. This work focuses on comparing these representations as well as the learned input features for different state-of-the-art convolutional neural network architectures. By focusing on the geometry of this …

Difficulties in the learning and teaching of linear algebra : a personal experience
Two different personal experiences of teaching Linear Algebra are analyzed: (1) teaching a college-level linear algebra course and (2) being the instructor in a predesigned experiment that investigates a geometric approach to the concepts of vector and linear transformations using the dynamic …

ACM: Atlas of Connectivity Maps
… or between connectivity maps using a set of linear transformations. We demonstrate the effectiveness of ACM for use in subdivision, multiresolution, and Digital Earth applications. In addition, the generality of ACM has been examined on a variety of face-types (e.g. triangles, hexagons, …

Statistical modelling for the prognostic classification of patients with pancreatic cancer for optimisation of treatment allocation
… are often simplified incorrectly i) assuming linear relationships between predictors and log-hazard or ii) using dichotomisation. Non-linearity is addressed for the first time in this disease site using restricted cubic spline and fractional polynomial functions. Multivariable models …
