Many methods have been developed since the first satellite was built. In this paper we propose a comparative study of the most important attitude representation methods adopted in the literature. We point out the advantages and disadvantages of each of these methods before choosing the one that suits our objective. Then we present, the Simulink blocks for Rotation angles method, which will be used in our attitude model. After that, we will present the implementation of this model in a system on chip, following the proposed architecture.}, isbn = {978-3-319-30301-7; 978-3-319-30299-7}, issn = {1876-1100}, doi = {10.1007/978-3-319-30301-7\_43}, author = {Bouras, Meryem and Berbia, Hassan and Nasser, Tamou}, editor = {ElOualkadi, A and Choubani, F and ElMoussati, A} } @conference { ISI:000380409500044, title = {On the Fetal Heart Rate Diagnostic Technologies}, booktitle = {2015 10TH INTERNATIONAL CONFERENCE ON INTELLIGENT SYSTEMS: THEORIES AND APPLICATIONS (SITA)}, year = {2015}, note = {10th International Conference on Intelligent Systems - Theories and Applications (SITA), ENSIAS, Rabat, MOROCCO, OCT 20-21, 2015}, publisher = {IEEE}, organization = {IEEE}, abstract = {Fetal heart rate and uterine contractions diagnosis are procedures used to evaluate the well-being of the fetus during pregnancy and labor. In this paper, we give a description of fetal heart rate, uterine contractions and also the most viable diagnostic technologies recording the vital signals of the fetal heart and those of the maternal heart and uterine contractions. We give a comparative study of these methods which are the Doppler ultrasound, the electrocardiogram and the use of piezoelectric materials.

We applied this algorithm over a Rician fading multipath channel in CODIT system, to symmetric and asymmetric PBC constructed from BCH and Quadratic Residue codes of rate 2/5 The results show that the proposed algorithm performances outperforms those of the concatenated Reed-Solomon/Convolutional coding scheme proposed in {[}1]. The excellent results obtained in this paper open broad prospects for iterative decoders based on the genetic algorithms.}, isbn = {978-1-4244-1751-3}, author = {Elbouanani, Faissal and Belkasmi, Mostafa and Berbia, Hassan} }
