1. A ROBUST COMBINATORIAL APPROACH BASED ON P-GRAPH FOR SUPERSTRUCTURE GENERATION IN DOWNSTREAM BIOPROCESSES
Abstract In the production of chemicals from fermentation, the cost of downstream purification constitutes the major portion of the total production cost. Since the bioprocess generally contains a large amount of biochemical separation units, its flowsheets are complex. How to generate the rigorous superstructure of the downstream bioprocess is a primary pro

2. Um modelo hierárquico para sistemas de tipos de arquivos implementado como um middleware / A hierarchical model for file type systems implemented as a middleware
Com a finalidade de facilitar a manipulação de documentos pelos usuários e aplicações, foram desenvolvidas no decorrer do tempo diversas formas para classificar e organizar esses documentos, incluindo a criação de diferentes mecanismos pertinentes a formatos de arquivos, os chamados sistemas de tipos de arquivos. É possível perceber nesse esforço u

3. Bird movement patterns in a fragmented landscape and their effects to functional connectivity: an hierarchical approach / Padrões de movimentação de uma espécie de ave em paisagens fragmentadas e seus efeitos para a conectividade funcional: uma abordagem hierárquica
Habitat fragmentation is one of the major human impacts on terrestrial ecosystems. This process highly affects the species movement pattern, implying in considerable alterations on the connectivity between the remaining habitat patches. Consequently, it interferes in the spatial distribution and in the population dynamics of species. In this dissertation, so

4. Fast two-step segmentation of natural color scenes using hierarchical region-growing and a color-gradient network
We present evaluation results with focus on combined image and efficiency performance of the Gradient Network Method to segment color images, especially images showing outdoor scenes. A brief review of the techniques, Gradient Network Method and Color Structure Code, is also presented. Different region-growing segmentation results are compared against ground

5. A generalized model for distributed comparison-based system-level diagnosis
This work introduces a new system-level diagnosis model and an algorithm based on this model: Hi-Comp (Hierarchical Comparison-based Adaptive Distributed System-Level Diagnosis algorithm). This algorithm allows the diagnosis of systems that can be represented by a complete graph. Hi-Comp is the first diagnosis algorithm that is, at the same time, hierarchica

6. Computação evolutiva empregada na reconstrução de arvores filogeneticas
This dissertation presents a study about one of the bioinformatic problems: the phylogenetic tree reconstruction. The solution space for this problem is calculated using a factorial formula. This is a combinatorial optimization problem. Evolutionary Computation, one of the component paradigms of computational intelligence, was proved to be a good tool to tac

7. Design of a directed molecular network
An ability to rationally design complex networks from the bottom up can offer valuable quantitative model systems for use in gaining a deeper appreciation for the principles governing the self-organization and functional characteristics of complex systems. We report herein the de novo design, graph prediction, experimental analysis, and characterization of s

8. A tool for filtering information in complex systems
We introduce a technique to filter out complex data sets by extracting a subgraph of representative links. Such a filtering can be tuned up to any desired level by controlling the genus of the resulting graph. We show that this technique is especially suitable for correlation-based graphs, giving filtered graphs that preserve the hierarchical organization of

9. SCOR: Structural Classification of RNA, version 2.0
SCOR, the Structural Classification of RNA (http://scor.lbl.gov), is a database designed to provide a comprehensive perspective and understanding of RNA motif three-dimensional structure, function, tertiary interactions and their relationships. SCOR 2.0 represents a major expansion and introduces a new classification organization. The new version represents
