After a brief survey on the parametric deformable models, we develop an iterative method based on the finite difference schemes in order to obtain energy-minimizing snakes. We estimate the approximation error, the residue, and the truncature error related to the corresponding algorithm, then we discuss its convergence, consistency, and stability. Some(More)
The noninvasive diagnosis of the malignant tumors is an important issue in research nowadays. Our purpose is to elaborate computerized, texture-based methods for performing computer-aided characterization and automatic diagnosis of these tumors, using only the information from ultrasound images. In this paper, we considered some of the most frequent(More)
In this paper, we describe briefly the 2D parametric deformable models, then we infer an algorithm, via Crank-Nicolson finite difference scheme for finding the so-called energy-minimizing (i.e. optimal) snake. The residue, the truncature - error and the order of accuracy related to this algorithm are estimated, in order to establish its consistency. We(More)
Business Process Model and Notation (BPMN), now at version 2.0.2, provides a standard graphical representation for specifying business processes. In this paper we report on the first stage of a semantic investigation of BPMN, using methods in the tradition of programming languages semantics. We consider a control-flow subset of BPMN and an execution(More)
Based on some mathematical and statistical approaches, our study leads to some conclusions concerning the procedures related to the orodental prosthetics. Occlusal equilibration in orodental prosthetics is a major issue because besides motivating patients for a regular daily oral hygiene, it could significantly increase the longevity of FPR.

This paper presents a Java framework for analyzing, processing and understanding wound images, to be used in teaching, learning and research activities. We intend to promote e-learning technologies in medical, pharmaceutical and health care domains. Using Java and XML technologies, we build models for various categories of wounds, due to various etiologies.(More)
In this paper we present the general conception and the mathematical background of a software environment aimed to provide enhanced remotely-sensed images processing capabilities. Integral and discrete transforms, multi-resolution analysis, reverse dynamics, symbolic computation principles and tools are involved. As mathematical background, this paper(More)
