Abstract:

The use and application of geometric transformations is a fundamental standard for the Common Core State Standards. This study was developed to determine current high school teachers’ prior mathematical content knowledge and develop their content knowledge of transformations and their applications. The design of this study was guided by the questions: “Why is there a level of reluctance amongst secondary teachers when it comes to teaching geometric transformations?” and “How can their content knowledge become deepened to apply geometric transformations to prove that two figures are congruent?”

Abstract:

This dissertation presents a technique for the solution of incompressible equivalents to planar steady subsonic potential flows. Riemannian geometric formalism is used to develop a gauge transformation of the length measure followed by a curvilinear coordinate transformation to map a subsonic flow into a canonical Laplacian flow with the same boundary conditions. The method represents the generalization of the methods of Prandtl-Glauert and Karman-Tsien and gives exact results in the sense that the inverse mapping produces the subsonic full potential solution over the original airfoil, up to

Abstract:

Reconhecimento de padrões em imagens é um problema clássico da área de visão computacional e consiste em detectar um padrão ou objeto de referência (template) em uma imagem digital. A maioria dos métodos para esta finalidade propostos na literatura simplifica as imagens por meio de operações como binarização, segmentação e detecção de bordas ou pontos de contorno, para em seguida extrair um conjunto de atributos descritores. O problema é que esta simplificação pode descartar informações importantes para descrição dos padrões, fazendo diminuir a robustez do processo de detecção. Um método efici

Abstract:

Similarity, being a psychological notion, involves the comparison of finite object representations. The specific nature and complexity of these representations is a matter of fierce theoretical debate traditionally, similarity research was dominated by the spatial and featural account. In the spatial account, similarity is determined by the distance between objects in a psychological space. Alternatively, the featural account proposes that similarity is determined by matching objects' features. Despite the empirical success of these accounts, the object representations they posit are regarded

Abstract:

Voice transformation refers to a class of techniques that modify the voice characteristics either to conceal the identity or to mimic the voice characteristics of another speaker. Its applications include automatic dialogue replacement and voice generation for people with voice disorders. The diversity in applications makes evaluation of voice transformation a challenging task. The objective of this research is to propose a framework to evaluate intentional voice transformation techniques. Our proposed framework is based on two fundamental qualities: intelligibility and speaker similarity. Int

The blurry boundary between clusters can be better revealed after transformation.

Abstract:

Automated map generalization is a necessary technique for the construction of multi-scale vector map databases that are crucial components in spatial data infrastructure of cities, provinces, and countries. Nevertheless, this is still a dream because many algorithms for map feature generalization are not parameter-free and therefore need human’s interference. One of the major reasons is that map generalization is a process of spatial similarity transformation in multi-scale map spaces; however, no theory can be found to support such kind of transformation.
