n las últimas décadas ha surgido como una nueva corriente para la protección de información la Teoría del Caos. Partiendo del principio de Kerckhoff, en donde se establece que la robustez de un sistema de seguridad criptográfica reside en la dificultad para obtener la clave, entonces los métodos de generación de claves deben poseer ciertas propiedades de aleatoriedad. Para propósitos prácticos ...

The most widely used change detection method is to classify remote sensing images independently for each date, and stack them to form a class sequence vector. However, impossible transitions within the sequences might occur and errors might be accumulated. To solve this, we propose a novel algorithm called Compound Maximum Likelihood (CML), based on the Maximum Likelihood classifier (ML). In CM...

Resumo. Os avanços nas simulações computacionais têm permitido o processamento de volumes de dados cada vez maiores. Para representar as estruturas de dados complexas inerentes de tais simulações, elas são armazenadas em arquivos de formatos heterogêneos. Carregar tais dados em um SGBD, como o SciDB, para apoiar as análises deles se torna uma tarefa complexa, ou mesmo inviável, devido ao seu vo...

A commonly cited maxim states that “you get what you pay for”, implying that there is a strong correlation between the price paid for something, and its quality. In this paper, we examine whether this often-cited wisdom applies to using crowdsourcing for conducting subjective QoE experiments, and if so, how. As part of a large-scale user study designed to assess Web QoE, we conducted two crowds...

A technique is described for constructing three-dimensional vector graphics representations of planar regions bounded by cubic Bézier curves, such as smooth glyphs. It relies on a novel algorithm for compactly partitioning planar Bézier regions into nondegenerate Coons patches. New optimizations are also described for Bézier inside–outside tests and the computation of global bounds of direction...

We propose a new clustering algorithm based upon the maximin correlation analysis (MCA), a learning technique that can minimize the maximum misclassification risk. The proposed algorithm resembles conventional partition clustering algorithms such as k-means in that data objects are partitioned into k disjoint partitions. On the other hand, the proposed approach is unique in that an MCA-based ap...

This document revises N1932 = Brown, et al.: Random Number Generation in C++0X: A Comprehensive Proposal. It incorporates all known corrections to that paper’s language and typography, including all emendations requested by the Library Working Group during its Berlin meeting (3–7 April, 2006). and also adopts the context of N2009 = Becker: Working Draft, Standard for Programming Language C++. C...

This paper describes formal bases for designing a PostScript dynamic font respecting some basic rules of Arabic calligraphy. This font will provide, for instance, a vertical curvilinear characters dynamic stretching that depends on their horizontal stretching according to the Calligraphic rules. Vertical and horizontal ligatures will also be supported by the proposed font. The techniques used c...
