1. A autoridade do professor no contexto da autoridade algorítmica digital,
Resumo Na história do desenvolvimento do processo de ensino e aprendizagem, a figura do professor sempre se destacou como de fundamental importância para que os alunos desenvolvessem suas capacidades cognitivas, afetivas e éticas. Porém, na sociedade da cultura digital, observam-se indícios de transformações radicais nessa relação, sobretudo porque

2. Venous thromboembolism in Latin America: a review and guide to diagnosis and treatment for primary care
There are various region-specific challenges to the diagnosis and effective treatment of venous thromboembolism in Latin America. Clear guidance for physicians and patient education could improve adherence to existing guidelines. This review examines available information on the burden of pulmonary embolism and deep vein thrombosis in Latin America and the r

3. Criação e performance musical no contexto dos instrumentos musicais digitais / Music creation and performance in the context of digital musical instruments
This work presents a study about the computer as an instrument for musical performance. Based on this study we developed processes of music creation using the algorithmic representation and the computer code. The two main technical resources we applied in our works were: a sound synthesis method based on the generation of waveforms by non-linear equations; a

4. Information retrieval system using Multiwords Expressions (MWE) as descriptors
This paper aims to propose an alternative method for retrieving documents using Multiwords Expressions (MWE) extracted from a document base to be used as descriptors in search of an Information Retrieval System (IRS). In this sense, unlike methods that consider the text as a set of words, bag of words, we propose a method that takes into account the characte

5. Teoria da informação algorítmica, eficiência relativa de mercado e perda de memória em séries de retornos de alta frequência em ativos negociados na BM&F BOVESPA. / Algorithmic information theory, relative market efficiency and memory loss in high frequency asset return series traded at BM &F BOVESPA.
O presente trabalho tem por objetivos: 1) aplicar a teoria da complexidade de Kolmogorov utilizando a medida proposta por Lempel e Ziv (1976) para analisar o comportamento desta diante de alterações em parâmetros como tamanho de janela, salto e de região de estabilidade em séries financeiras de retornos de alta freqüência de ativos negociados na BM&F

6. Um modelo de dados para objetos moveis
The popularization of devices like G PS and wireless network have enabled new applications that collect and analyze mobile objects. Traditional database system do not support the management of mobile object data, since a great amount of information is generated continuously. Research in this area is recent with relatively few works on mobile data management.

7. Enfoques en torno al modelo cognitivo para la recuperación de información: análisis crítico
The traditional or algorithmic model of information retrieval has evolved into the cognitive model. From the latter, different proposals for practical implementation have arisen being the most remarkable ones those labelled by their own authors as Global Model of Polirepresentation, Episodic Model, Stratified Model and Model of Interactive Feedback. These ar

8. Sporadicity: Between periodic and chaotic dynamical behaviors
We define the class of sporadic dynamical systems as the systems where the algorithmic complexity of Kolmogorov [Kolmogorov, A. N. (1983) Russ. Math. Surv. 38, 29-40] and Chaitin [Chaitin, G. J. (1987) Algorithmic Information Theory (Cambridge Univ. Press, Cambridge, U.K.)] as well as the logarithm of separation of initially nearby trajectories grow as nv0(l

9. Algorithmic Self-Assembly of DNA Sierpinski Triangles
Algorithms and information, fundamental to technological and biological organization, are also an essential aspect of many elementary physical phenomena, such as molecular self-assembly. Here we report the molecular realization, using two-dimensional self-assembly of DNA tiles, of a cellular automaton whose update rule computes the binary function XOR and th

10. Generation, description and storage of dendritic morphology data.
It is generally assumed that the variability of neuronal morphology has an important effect on both the connectivity and the activity of the nervous system, but this effect has not been thoroughly investigated. Neuroanatomical archives represent a crucial tool to explore structure-function relationships in the brain. We are developing computational tools to

11. Revealing modularity and organization in the yeast molecular network by integrated analysis of highly heterogeneous genomewide data
The dissection of complex biological systems is a challenging task, made difficult by the size of the underlying molecular network and the heterogeneous nature of the control mechanisms involved. Novel high-throughput techniques are generating massive data sets on various aspects of such systems. Here, we perform analysis of a highly diverse collection of ge
