The Intelligent Forecast System (IFS) consists of three units: the main unit is a multilayer neural network1 the second unit is based on fuzzy logic, which is used to prepare the data1 and the third unit is based on a genetic algorithm and is used to determine the best set of data to be analyzed. The data were set up by using a strategy that classifies the terms of the series into parts with the same quantity of elements. Each part is called a window. The IFS was trained by using a group of windows, which is called a set of training windows. Next, the IFS was applied to solve several problems related to the evaluation of structural integrity. The IFS was applied as an identification strategy and forecast of parameters in a flexible structure. Additionally, by using the IFS we have developed a new strategy to analyze the temporary series obtained from vibrations of flexible structures with the distribution of variable mass. The results obtained in this research, using the IFS applied as an identification strategy and forecast of parameters in a flexible structure, show the effectiveness of the IFS.

In this work they were developed a microcontroller-based system devoted to the newborn incubator, in order to check the conditions of the environment provided to the premature newborns, a control system of humidity and software that carries out the reading of the sensors. Two microprosecuted, similar newborn incubator were used, for the realization of the measurements, being that one of the newborn incubator used distilled water and other one was valued without water. The measures were collected to each 2 minutes during 96 h. The relative humidity inside of the newborn incubator, without water had average (46.53 ± 3.84) %. The mean value of the internal temperature was of (36.58 ± 1.04) ºC. With water, without control of humidity, (70.67 ± 3.71) %. The mean value of the internal temperature was of (34.33 ± 1.84) ºC. With water and with control of humidity, was inside the established belt of comfort for the standard. One checked that the newborn incubator used in this inquiry does not provide to the premature newborns a totally appropriate environment taking into account the requisites of the standard NBR IEC 601-2-19.
