1. Bibliotecas Digitais: modelo metodológico para avaliação de usabilidade
It aims to analyze and develop methodology for evaluation of digital libraries with a focus on usability. This study discusses aspects of the evaluation of digital libraries, considered as information devices that assist in the democratization of information mediated by technologies. Such libraries can be understood as environments for organization, storage,

2. Arquitetura modular de processador multicore, flexível, segura e tolerante a falhas, para sistemas embarcados ciberfísicos. / Modular multicore processor architecture, flexible, securi and fault tolerant, to embedded cyber-physical systems.
Cyber-physical Systems (CPS) are systems where there is an union between computing and physics. The CPS will be used in several areas, forming a new era of systems or devices and could be anywhere, being used by anyone and anything. Applications for CPS include highly reliable medical systems and devices, traffic control and security, advanced automotive, pr

3. Criação de modelos organizacionais para cidades digitais baseadas em uma arquitetura peer-to-peer / Building organization models for digital cities peer-to-peer based
Support by the growing of digital cities projects, the main goal of this work is to propose an architecture and an organizational model of information exchange in a digital city building an infrastructure of deploying and consumption of services by citizens. This model aim to promote citizen access to city services and provide easy and wide digital media ava

4. Proposal and development of a reconfigurable associativity algorithm in cache memories. / Proposta e desenvolvimento de um algoritmo de associatividade reconfigurável em memórias cache.
With the constant evolution of processors architecture, its getting even bigger the overhead generated with memory access. Trying to avoid this problem, some processors developers are using several techniques to improve the performance, as the use of cache memories. By the otherside, cache memories cannot supply all their needs, thats why its important some

6. A autocrítica da arquitetura mediada pelo ambiente digital: o drama dos espaços possíveis
This piece of research deals with the architecture mediated by the digital environment. This environment is defined taking into consideration the computer as a device in continuance with the symbolic processes associated with its use. The architecture object of this study dates from the 90s of the twentieth century and the first four years of the twenty-firs

7. Mapeamento de informações em sistemas corporativos Uma arquitetura da informação aplicada à Embrapa
The information stored in computer systems are, generally, unknown by the members of an organization. Many times the information needed is available, but people didnt know how to take them and neither about their existence. In the presence of that necessity, the next question was treated: how to locate the organizations informations from your systems informa

8. BUILDING AN ARCHITECTURE STRATEGIC CORPORATE MEMORY BASED ON A BUSINESS MODEL / CRIANDO UMA ARQUITETURA DE MEMÓRIA CORPORATIVA BASEADA EM UM MODELO DE NEGÓCIO
This work presents a proposal for building corporate memory architecture. It has three layers: sources, middleware and repositories. First, we create an conceptual enterprise model, named Organizational Baseline (OB), based on theories of business management and organized in accordance with an approach of ontology. Second, we use multi agents system as a mea

9. BLOOM BLAST Object Oriented Management: uma solução integrada para gerenciamento dos resultados do BLAST por meio de um paradigma orientado a objetos
Considered a special subject since the beginning of the 80s, bioinformatics can be defined as a way that covers all aspects of acquisition, processing, storage, distribution, analysis and interpretation of biological information. All this happens in a narrow sinergy with the molecular biology fundamental paradigm, which postulates that the genetic informatio

10. Tertiary Structure of Bacterial Murein: the Scaffold Model
Although the chemical structure and physical properties of peptidoglycan have been elucidated for some time, the precise three-dimensional organization of murein has remained elusive. Earlier published computer simulations of the bacterial murein architecture modeled peptidoglycan strands in either a regular (D. Pink, J. Moeller, B. Quinn, M. Jericho, and T.

11. Preexisting nuclear architecture defines the intranuclear location of herpesvirus DNA replication structures.
Herpes simplex virus DNA replication proteins localize in characteristic patterns corresponding to viral DNA replication structures in the infected cell nucleus. The intranuclear spatial organization of the HSV DNA replication structures and the factors regulating their nuclear location remain to be defined. We have used the HSV ICP8 DNA-binding protein and

12. Electroanatomy of a unique amacrine cell in the rabbit retina.
Intracellular electrophysiological recordings were obtained from a specialized class of "starburst" amacrine cells by using an isolated superperfused retina-eyecup preparation of the rabbit. These cells were injected intracellularly with horseradish peroxidase and identified with light microscopy. A computer-controlled image-processing system was used to map
