1. Clock mesh optimization / Otimização de malhas de relógio
Clock meshes are a suitable clock network architecture for reliably distributing the clock signal under process and environmental variations. This property becomes very important in the deep sub-micron technology where variations play a main role. The clock mesh reliability is due to redundant paths connecting clock buffers to clock sinks, so that variations

2. The impact of spatial data redundancy on SOLAP query performance
Geographic Data Warehouses (GDW) are one of the main technologies used in decision-making processes and spatial analysis, and the literature proposes several conceptual and logical data models for GDW. However, little effort has been focused on studying how spatial data redundancy affects SOLAP (Spatial On-Line Analytical Processing) query performance over G

3. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

6. Wavelet-packet identification of dynamic systems in frequency subbands.
This work presents a technique for linear system identification in frequency subbands by using wavelet packets. The wavelet-packet decomposition tree is used to establish frequency bands where subband models are created. An algorithm is proposed to adjust the tree structure, in order to achieve a compromise between accuracy and parsimony of the model. In a s

8. Estrategias de detecção e diagnostico de falhas em sistemas dinamicos
Analytical redundancy for fault detection and diagnosis of dynamic systems, FDD, has been approached by several methodologies, state estimation, parameter estimation, expert systems, and pattern classification and recognition being typical examples. In particular, pattern classification and recognition methods adopt probabilistic, heuristic, neural, and fuzz

9. An assessment of Motorola CodeLink™ microarray performance for gene expression profiling applications
DNA microarrays enable users to obtain information on differences in transcript abundance on a massively parallel scale. Recently, however, data analyses have revealed potential pitfalls related to image acquisition, variability and misclassifications in replicate measurements, cross-hybridization and sensitivity limitations. We have generated a series of an
