Blind source separation / Qasem Bendermel 

Public ISBD Titre : Blind source separation Type de document : texte imprimé Auteurs : Qasem Bendermel, Auteur ; Mohamed Arezki Adel Belouchrani, Directeur de thèse ; M. Adnane, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2017 Importance : 40 f. Présentation : ill. Format : 30 cm. Accompagnement : 1 CD-ROM. Note générale : Mémoire de Master : Electronique : Alger, Ecole Nationale Polytechnique : 2017 Bibliogr. f. 39 - 40 Langues : Anglais (eng) Mots-clés : Blind  source  separation Independent  Component  Analysis Signal  process-ing Index. décimale : Ms13317 Résumé : Blind Source Separation (BSS) is a statistical approach to separating individual signals from an observed mixture of a group of signals. BSS relies on only very weak assumptions on the signals and the mixing process and this blindness enables the technique to be used in a wide variety of situations. Research in the field of Blind Source Separation has resulted in the development of a family of algorithms, known as Independent Component Analysis (ICA) algorithms, that can reliably and efficiently achieve blind separation of signals. There are two important problems that are generally considered: instantaneous BSS and convolutive BSS. The difference between these two is based on the nature of the signal mixing process. In this thesis, the mathematical foundations of both instanta-neous and convolutive BSS are developed. Once this mathematical framework has been established, the emphasis of the thesis moves to experimental results obtained with ICA techniques .

Design and implementation of a plantar pressure measurement system / Hadjer Azli 

Public ISBD Titre : Design and implementation of a plantar pressure measurement system Type de document : texte imprimé Auteurs : Hadjer Azli, Auteur ; Insaf Bouguezine, Auteur ; M. Adnane, Directeur de thèse ; Mohamed Arezki Adel Belouchrani, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2017 Importance : 89 f. Présentation : ill. Format : 30 cm. Accompagnement : 1 CD-ROM Note générale : Mémoire de Projet de Fin d'Etudes : Electronique : Alger, Ecole Nationale Polytechnique : 2017 Bibliogr. f. 78 -80 . Appendix f. 81 - 89 Langues : Anglais (eng) Mots-clés : Gait  analysis Plantar  systems Non-wearable  sensors Piezoresistive  technology Pressure  platforms Index. décimale : PN00117 Résumé : The aim of this thesis is to design and build a plantar pressure sensing system which consists main ly of a piezoresistive technology based mat. The design is inspired by a pressure sensing matrix model and presents a maximum attainable spatial resolution of 1.7cmx1.4cm. Data is acquired using an NI USB-6002 board. An application is implemented using NI LabVIEW 14.0 in order to process the collected data and visualize the output of the system. This latter includes two types of plantar profile pressure images: A binary-level real time display of the subject’s footprint and a grey-level display of the plantar pressure at each sensing unit of the plat form. This interface can be used by a therapist to extract some spatial parameters and determine gait abnormalities.
