1. Investigations on Preparation and Characterization of Certain Copolyesters
In this paper, we report on the synthesis and characterization of high molecular weight copolyesters from Terephthalic acid, 1, 4 butane diol and Succinic acid /Sebacic acid through a two step process of melt polycondensation using titanium tetra butoxide as catalyst. The synthesized aromatic-aliphatic random copolyesters were characterized by means of FTIR,

2. Síntese e customização de terrenos a partir de modelos digitais de elevação / Terrain synthesis and customization from digital elevation models
Este trabalho apresenta uma abordagem para síntese de terrenos a partir de modelos digitais de elevação (DEM). O desenvolvimento de novas técnicas de visualização de terrenos, apoiado no rápido crescimento do poder computacional, fez aumentar a demanda por modelos de terrenos com maior realismo. Jogos de computador, simuladores de vôo e efeitos espec

3. A obtenção de texturas na síntese de imagens realísticas num ambiente limitado
As técnicas para síntese de textura em Computação Gráfica constituem um grupo bem específico cujo objetivo principal é a inclusão, na imagem, de alguma informação visual que aumente a percepção de realismo. São identificadas técnicas para síntese de textura com características favoráveis a implementação num ambiente limitado cujo aspecto c

4. Efecto del pH en la síntesis de hidroxiapatita en presencia de microondas
Synthetic hydroxyapatite, Ca10(PO4)6(OH)2, is a biomaterial used to reconstruct damaged bone tissue or to recover protheses. Indeed, the chemical composition and structure is similar to the mineral phase contained in the scheleton. This similarity favors the formation of bonds with the bone, it becomes then a biocompatible material. Hydroxyapatite may be obt

5. CompressÃo de texturas utilizando sÃntese de texturas
In spite of graphics hardware advancements, graphics memory is still a scarce resource for usual applications. Besides, for most raster-based applications, the available bandwidth is one important limiting factor for increasing performance in the system. Texture compression addresses both of these problems. We introduce a new technique for texture compressio

6. Wavelet transform in digital inpainting / Aplicação de wavelets em inpainting digital
Digital Inpainting is a recent techinique that allows the filling of missing information in images. One important attribute of a digital inpainting technique is the ability of altering an image in such a way that it is not simple for the human observer to detect the modification, characterizing an undetectable modification. The strategies for filling missing

7. Estudo clinico-molecular e analise da textura epidermica de pacientes com sindrome de Sjogren-Larsson / Molecular genetic study and texture analysis of the epidermis in patients with Sjogren-Larsson Syndrome
Background: Sjögren-Larsson syndrome (SLS) is an autosomal recessive disorder characterized by ichthyosis, mental retardation, and spasticity. Various mutations in the ALDH3A2 gene that codes for fatty aldehyde dehydrogenase (FALDH) are responsible for the disease but the genotype-phenotype relationships are undefined. Objectives: The purpose of this study

8. Uma abordagem baseada em texels para síntese de texturas que variam progressivamente
We present a model for texture synthesis from samples, particularly for synthesis of textures with smooth variation of the texture elements, known as Progressively-Variant Textures (PVT). This type of textures is common in Nature, specially in animal coat markings such as leopards. Current solutions, for the most part, do not allow much control by the user o

9. Recent progress in the synthesis and characterization of amorphous and crystalline carbon nitride coatings
This review summarizes our most recent findings in the structure and properties of amorphous and crystalline carbon nitride coatings, synthesized by reactive magnetron sputtering. By careful control of the plasma conditions via proper choice of process parameters such as substrate bias, target power and gas pressure, one can precisely control film structure

10. Texturesynthesisusingstasticalspatialmodels / Síntese de textura utilizando modelos estatísticos espaciais
The scope of this work is the use of methods capable of generating natural looking synthetic textures reproducing previously selected source patterns. Spatial statistic models are the basis for the used methods, specifically autoregressive moving average modeling for parameter estimation and texture pattern generation. Two methods are used for parameter esti

11. Estudo de compostos de intercalação de Fe OCI : sintese, caracterização e propriedades
In this study we have synthetised FeOCl and some of its intercalation compounds involving Lewis bases as intercalants: n-buthylamine (nBA), triethylamine (TEA), benzylamine (BZA), ethylenediamine (EDA) and diethylenetriamine (DTA). These synthesis were optimized through the control of some reaction parameters such as temperature and time. The reactions were

12. Texturas em sintese de imagens
This work presents a study of textures in Image Synthesis environments. A review of some well known methods for modeling textures and applying them to synthetic objects is presented. Based on our experience in texturing and the study of physical phenomena related to the observed texture a General Model for Textures and the specification for a Texture Module
