— Currently there are three basic types of pattern recognition, the syntactic, the statistical and the neu-ral types. They all have advantages and disadvantages, some of which are troublesome. In statistical methods it is difficult to express structured information. Neural methods have problems to represent neural networks semantically. In syntactic methods(More)
This paper presents an overview of current work on the recognition of sign language and a prototype of a simple editor for a small subset of the Brazilian Sign Language, LIBRAS. Handshape based alphabetical signs, are captured by a single digital camera, processed on-line by using computational vision techniques and converted to the corresponding Latin(More)
The aim of the present paper is to revisit some important topics regarding pedagogical issues on the teaching of concepts and t echniques of programming languages and compiler construction. Essentially, a unified formal model is used in the proposed approach to explore the exposition of the students to a set of lessons with growing complexity, with a heavy(More)
Synchronized Statecharts [1] have shown to be adequate devices for expressing most features of real-time and reactive systems. The emphasis is in the explicit statement of orthogonal aspects, such as internal behavior, communication interfaces and synchronization issues of the system being modeled. This paper explores Adaptive Statecharts, which improves(More)
