37. Comparative study of algorithms of image compression for transmission in computer networks / Estudo comparativo de algoritmos de compressÃo de imagens para transmissÃo em redes de computadores
Recentemente, foram desenvolvidos algoritmos iterativos de compressÃo destinados à transmissÃo de imagens estÃticas via rede tais como: JPEG progressivo, JPEG2000 progressivo, PNG entrelaÃado e GIF entrelaÃado. Esses algoritmos decompÃem a imagem e a transmitem de forma nÃo seqÃencial. O propÃsito desta dissertaÃÃo consiste em efetuar um estudo c

38. To listen eletrolaryngeal speakers: oral communication, expressiveness and sense effects / Ouvir o falante eletrolaríngeo: comunicação oral, expressividade e efeitos de sentido
Electrolaryngeal speech has specificities that may affect the communicative relationship between total laryngectomized patients and their interlocutors. The purpose of the present study was to get to know and to analyze the impressions and interpretations of listeners concerning electrolaryngeal speech with and without the image of laryngectomized patients d

40. Automatic detection of significative events and summarization in soccer transmissions / Detecção automática de eventos siginificativos e sumarização em transmissões de futebol
The automatic summarization of a sporting video is resume a important data, is a task that involves analysis of a specific content in video hours. We propose here to use techniques of Computer Vision and Patterns Recognition to detect and classify highlights in a soccer game through images transmitted by TV. Texture and space characteristics will be used (co

41. Aesthetics, semiotics, and pragmatism -Basis to a Peircean philosophy of art. / Estética, pragmatismo &Semiótica: Bases para uma filosofia da arte peirceana
This thesis is a reflection about the work of art, found mainly in Charles Sanders Peirces Phenomenology, Semiotics, Aesthetics, and Pragmatism. In the following three chapters we will try to show evidence of an implicit Philosophy of Art in the authors vast work. First, in Phenomenology of Art, the problem of the nature of artwork surfaces through a discuss

42. Entre a oralidade e a escrita: percepções e usos do discurso etnográfico no candomblé da Bahia. / Between orality and writing: perceptions and uses of ethnographic discourse in Bahia candomblé.
In studies of Afro-Brazilian religion, the idea that the transmission of religious knowledge in candomblé terreiros occurs via exclusively oral means has long been paradigmatic. Since the 1980s, however, the possibility that ethnography itself may exert an influence over this ?oral tradition? has come under scrutiny. According to some, ethnographic discours

43. Ceramic foams porous microstructure characterization by X-ray microtomography
Knowledge of the porous structure of amorphous materials is of fundamental importance in calculating geometrical parameters such as total porosity, pore size distribution and physical parameters relating to fluid flow inside void space. The present work deals with the measurement of the microstructural parameters of porous ceramic filters. Microtomographic m

44. Development of a simulator for tomographic images generated by radiation transmission
A computer program to simulate tomographic images generated by transmitted radiation was developed. The algorithm uses a deterministic approach to generate the projections, which supply an existing image reconstruction software. A dispersion associated with the counting statistics is also incorporated into the algorithm, in order to simulate the influence of

45. Analysis of concrete material through gamma ray computerized tomography
Computerized Tomography (CT) refers to the cross sectional imaging of an object from both transmission or reflection data collected by illuminating the object from many different directions. The most important contribution of CT is to greatly improve abilities to distinguish regions with different gamma ray transmittance and to separate over-lying structures

46. Procedência de dados: teoria e aplicações ao processamento de imagens / Data provenance: theory and aplication to image processing
The provenance is a complementary data documentation. It contains a description of "how", "when", "where", "why" the data were obtained and "who" obtained it. The provenance includes not only the origin of the data but also the description of the processes that produce them (algorithms and their respective parameters). Data provenance might be very helpful i

48. Restauração de imagens do satélite Landsat-7. / Restoration of LANDSAT-7 satellite images.
The techniques of image restoration are oriented for the modeling of the degradation and recovery of the original signal that was degraded during the process of image formation. In Remote Sensing, sensor?s nominal spatial resolution, that defines the precision with which details of objects of interest in the image are perceivable, is one of the most importa
