A Case Based Methodology for Problem Solving aiming at Knee Osteoarthritis Detection

Knee osteoarthritis is the most common type of arthritis and a major cause of impaired mobility and disability for the ageing populations. Therefore, due to the increasing prevalence of the malady, it is expected that clinical and scientific practices had to be set in order to detect the problem in its early stages. Thus, this work will be focused on the improvement of methodologies for problem solving aiming at the development of Artificial Intelligence based decision support system to detect knee osteoarthritis. The framework is built on top of a Logic Programming approach to Knowledge Representation and Reasoning, complemented with a Case Based approach to computing that caters for the handling of incomplete, unknown, or even self-contradictory information.

Age Prediction through Pelvis X-Ray Images - A Case Based approach to Problem Solving

It is well known that the dimensions of the pelvic bones depend on the gender and vary with the age of the individual. Indeed, and as a matter of fact, this work will focus on the development of an intelligent decision support system to predict individual’s age based on pelvis’ dimensions criteria. On the one hand, some basic image processing technics were applied in order to extract the relevant features from pelvic X-rays. On the other hand, the computational framework presented here was built on top of a Logic Programming approach to knowledge representation and reasoning, that caters for the handling of incomplete, unknown, or even self-contradictory information, complemented with a Case Base approach to computing.

Research on the First Musique Concrète: The Case of Xenakis’s First Electroacoustic Pieces

Xenakis’s first electroacoustic pieces (Diamorphoses, 1957; Concret PH, 1958; Analogique B, 1959; Orient-Occident, 1960; and Bohor, 1962) can be called musique concrète. Indeed, these works use the concrète musique tape techniques. But their spirit and aesthetic is very different from those set forth in Pierre Schaeffer’s theories. In fact, these works are quite particular in their whole conception. The two authors of this article are researching this period of Xenakis’s electroacoustic music. In this article, they offer a brief survey of the issues these works raised. To illustrate some of these issues, they use Diamorphoses and Bohor as examples.
