This paper presents a fast and reliable method to trim non-solution regions in an interval ray tracing process. The " trimming algorithm " uses interval analysis to perform rejection tests in a set of pixels simultaneously, instead of individual pixels at each time. With this approach, the presented algorithm runs faster than the traditional interval ray(More)
One of the techniques used to detect faults in dynamic systems is analytical redundancy. An important difficulty in applying this technique to real systems is dealing with the uncertainties associated with the system itself and with the measurements. In this paper, this uncertainty is taken into account by the use of intervals for the parameters of the(More)
In this paper, a new algorithm based on Set Inversion techniques and Modal Interval Analysis is presented. This algorithm allows solving problems involving quantified constraints over the reals through the characterization of their solution sets. The presented methodology can be applied over a wide range of problems involving uncertain (non)linear systems.(More)
In this paper the analysis, design and implementation of a soccer team of micro-robots is explained. Besides the technical difficulties to develop these micro-robots, this paper also shows how to develope a multi-agent cooperative system by means of Matlab/Simulink † a widely known Computer Aided Control System Design framework. Agent-Oriented Paradigms(More)
Interval models may be used in many cases to express the imprecision and the uncertainty related to complex systems. The envelopes may be used to represent the results of the simulation of these models. One of the applications of the envelopes is as reference behaviour for Fault Detection (FD) based on analytical redundancy. In this case, the properties of(More)
The artificial pancreas aims at the automatic delivery of insulin for glycemic control in patients with type 1 diabetes, i.e., closed-loop glucose control. One of the challenges of the artificial pancreas is to avoid controller overreaction leading to hypoglycemia, especially in the late postprandial period. In this study, an original proposal based on(More)
Evaluation of metabolic control of diabetic people has been classically performed measuring glucose concentrations in blood samples. Due to the potential improvement it offers in diabetes care, continuous glucose monitoring (CGM) in the subcutaneous tissue is gaining popularity among both patients and physicians. However, devices for CGM measure glucose(More)
