1. Modification of Haessler’s sequential heuristic procedure for the one-dimensional cutting stock problem with setup cost
Abstract Paper aims We propose a modified Sequential Heuristic Procedure (MSHP) to reduce the cutting waste and number of setups for the One-Dimensional Cutting Stock Problem with Setup Cost. Originality This heuristic modifies Haessler’s sequential heuristic procedure (1975) by adapting the Integer Bounded Knapsack Problem to generate cutting patterns

2. Discrete Geometry and Codes / Geometria discreta e codigos
The research developed here is related and inspired by problems in coding theory. It is presented in two parts. In the first we focus on the search for the minimum nonvanishing vector of a lattice, specially in the case of a projection of the ndimensional integer lattice in the direction of one of its vectors. This is a problem of high computational complexi

4. MOTION ESTIMATION METHOD WITH SUBPIXEL RESOLUTION OF CODEC H264/AVC / MÉTODOS DE ESTIMAÇÃO DE MOVIMENTO COM RESOLUÇÃO EM SUBPIXEL NO CODEC H264/AVC
The MPEG (Moving Picture Experts Group) and the VCEG (Video Coding Experts Group) have developed a new video compression standard entitled AVC (Advanced Video Coding). This standard offers the capacity of video compression greater than the previous standards.The motion estimation which is a phase of the video compression is extremely computer-intensive and t

5. Alguns resultados em teoria de partições e teoria de codigos
This thesis consists of the publications done by the candidate. In these publications we have used many combinatorial to01s inc1uding: generating functions, q-calculus, various properties of sequences of integer numbers etc. were used in the theory of partitions and the coding theory. The thesis consists of six papers: three of them take into consideration c

6. A TRANSFORMADA DE BURROWS-WHEELER E SUA APLICAÇÃO À COMPRESSÃO / THE BURROWS-WHEELER TRANSFORM AND ITS APPLICATIONS TO COMPRESSION
The Burrows-Wheeler Transform, based on sorting of contexts, transforms a sequence of characters into a new sequence easier to compress by an algorithm that exploits long sequences of repeted characters. Combined with the coding provided by the MoveToFront Algorithm and followed by a codification for the generated integers, they propose a new family of compr

7. ANÁLISE DE DESEMPENHO DA MODULAÇÃO MULTI-H EM CANAIS NÃO LINEARES LIMITADOS EM FAIXA / PERFORMANCE OF MULTI-H MODULATION OVER NON-LINEAR, BAND LIMITED CHANNELS
Error correcting codes have been used in power limited digital communication systems to improve the system error probability performance. This performance improvement is obtained at the price of an expanded occupied bandwidth or a lower rate of information transmission. Integrated coding and modulation techniques allow an increased performance without this b

8. Bacterial start site prediction.
With the growing number of completely sequenced bacterial genes, accurate gene prediction in bacterial genomes remains an important problem. Although the existing tools predict genes in bacterial genomes with high overall accuracy, their ability to pinpoint the translation start site remains unsatisfactory. In this paper, we present a novel approach to bacte

9. Variation in the Number of Genes Coding for Salivary Amylase in the Bank Vole, CLETHRIONOMYS GLAREOLA
A Danish population of bank voles is polymorphic for three electrophoretically different salivary amylases, A, H and S, of which A is the most common. Both single-, double- and triple banded phenotypes were observed, and in several crosses two electrophoretic forms cosegregated. In addition to the qualitative variation, some individuals show consistent quant
