13. Memoria e imagen
Image and narration are intrinsically related when the transmission of memory is at stake. This is so, not only because of the iconic dimension of the words, that make any story a projective screen of our imagination, but also due to the narrative character of images, although these very often require the proximity of the word. In both cases the idea of tran

14. Extended cell-transmission-based evacuation planning in urban areas
A well-known traffic simulation model bases on the idea to represent street sections by so-called cells where vehicles are streaming from one cell to another in order to give a realistic image of traffic flows. Its basic ideas were picked up recently to formulate an optimization model for evacuationplanning purposes. We will address three major weaknesses of

15. Preparation of nanodimensional CdS by chemical dipping technique and their characterization
A simple and cost effective chemical technique has been utilized to grow cadmium sulphide (CdS) nanoparticles at room temperature. The sample is characterized with XRD (X-ray diffractometer), SEM (Scanning electron microscope), TEM (Transmission electron microscope) and UV-VIS spectrophotometer. The particle size estimated using X-ray line broadening method

16. Stochastic texture image estimators for local spatial anisotropy and its variability
A new image analysis technique is proposed for the evaluation of local anisotropy and its variability in stochastic texture images. It utilizes the gradient function to provide information on local anisotropy, from two-dimensional (2-D) density images for foil materials like polymer sheets, nonwoven textiles, and paper. Such images can be captured by radiogr

17. Sistema de alto desempenho para compressão sem perdas de imagens mamográficas
The usage of mammographic image databases in digital form and the practice of telemedicine require to store and to transmit large amounts of data. The image digitization from a single mammographic exam with appropriate resolution can take up to 120MB of space in disk, which becomes even more critical when considering the large number of exams per day on a cl

18. Integrando sistemas de auxílio ao diagnóstico no sistema gerenciador de imagens médicas / Integrating computer-aided diagnosis systems into the picture archiving and communication system
The technology evolution seen in the last years provided large adoption of digital image acquisition equipments, such as: X-rays, computed tomography, magnetic resonance and ultrasound. The use of these devices in daily hospital routine generates an expressive image data volume which demands intelligent solutions for image storage, distribution and visualiza

19. Meios e modos da composição on-line : um processo poético da busca / Ways and means of composition online : a case of poetic search
This paper proposes a reflection of the ways and means of using the network composition and manipulation of images on-line in a set of procedures through digital capture and applications resulting from a search in the search for a contemporary artistic production. To realize this proposal a cut in my artistic production, watch a series of works that move and

20. Evaluation of influence of DICOM and JPEG formats in the reproducibility of cephalometric landmarks in digital Frontal Teleradiographies / Avaliação da influência dos formatos DICOM e JPEG na reprodutibilidade de pontos cefalométricos em Telerradiografia digital em Norma Frontal
The digital image on DICOM format request a large store size capability, making difficult the transmission through internet, usually requesting the image compression via JPEG file format. The aim of this study was to evaluate the influence of DICOM and JPEG file formats on Quality Factors 100, 80 and 60, in the reproducibility intra and interexaminer at ceph

21. A escolarização dos conteúdos imagéticos da biologia: um estudo das práticas de construção e execução de aulas pelo professor de biologia
This investigation aims to understand role of the teacher on the schools practices of transmission of the biological sciences images contents inside the classrooms. For this were identified and described teacher practices in the class, the functions developed by biological images in class and the characteristics that become different in the image when this i

22. Hydrophobicity classification in high voltage polymeric insulators / Classificação da hidrofobicidade em isoladores elétricos poliméricos de alta tensão
The aim of this study is to propose a new method to classify the hydrophobicity (HC) in high voltage polymer insulators. Currently the HC is based on the STRI guide (Swedish Transmission Research Institute) published in 1992, where the hydrophobicity is classified by contact angle and/or amount of wet surface. In the proposed method, the HC was analyzed by d

24. CONSTRUCTING THE IMAGE ON THE TV NEWS: PERCEPTIVE AND PERSUASIVE PROCESSES / A CONSTRUÇÃO DA IMAGEM NO TELEJORNALISMO: PROCESSOS PERCEPTIVOS E PERSUASIVOS
How can a box generate images? This was the concern of many Brazilians in relation to the television, when it arrived in Brazil. Since the beginning of the transmission, TV has passed for huge transformations. The number of channels has increased, and for consequence new programs and languages were created. These were enough to enrich what was shown on this
