The analysis and interpretation of high-dimensional biomedical datasets for the purposes of confirmatory or exploratory data analysis is a challenging problem. The process raises issues that are not only typically associated with high-dimensional data but also with software implementations of the visualization models. The relative distance plane projection method, which uses a distancebased map...

Two-dimensional patterns are used in many research areas in computer science, ranging from image processing to specification and verification of complex software systems (via scenarios). The contribution of this paper is twofold. First, we present the basis of a new formal representation of two-dimensional patterns based on contours and their compositions. Then, we present efficient algorithms ...

The phenomenological model of Khossravi and Connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. The accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (APMD). The obtained APMD for correlative and predictive studies ...

The paper addresses the problem of face recognition from range images. A novel technique based on matching of level contours is proposed and compared with a variant of the point signatures algorithm. Their efficiency is investigated on conditions of changes in expression and pose, and presence of glasses. Using a large database of range images, comparative experimental results are presented, sh...

This paper presents a novel method for quickly filtering range data points to make object recognition in large 3D data sets feasible. The general approach, called " 3D cueing, " uses shape signatures from object models as the basis for a fast, probabilistic classification system which rates scene points in terms of their likelihood of belonging to a model. This algorithm, which could be used as...

This paper presents and describes a Web-based implementation of a three-dimensional software quality measurement model. The implementation is based on the 2003 version of the ISO quality model for software products: ISO 9126. The prototype presented includes all the 120+ measures proposed in the ISO standard, as well as weight assignments, target values, current project values and automated cal...

Web-based collaboration is becoming increasingly common. Often such collaboration exhibits emergent characteristics, for which systems based on a notion of workspaces provide suitable support. Virtual teams collaborating in this manner create virtual organizational structures, the capture and retention of which into organizational memory promises to be of benefit, as it can facilitate reuse. Vi...

We describe results carried out using the parallel software PAR TFEM developed to address high intensive numerical simulations of the dynamic of three dimensional viscoelastic fluids. The software relies on PETSc (Portable, Extensible Toolkit for Scientific Computation) components integrated with the finite element solver (TFEM), already employed by chemical engineers for addressing bi dimensio...

This paper presents, a simulator that aims the development and design of cellular-automata based cryptographic algorithms. This software is necessary mainly in order to choose a (large) set of local rules as possible keys that should be integrated in hardware. The software accepts linear and two-dimensional cellular automata having variable dimensions, limited to 100/100 cells (that gives a max...
