    Task partition based parallel design and implementation of the MSSM algorithm on network of transputers
    (1995) Cheref, Mohamed
    The present work is concerned with the parallel design and implementation of the multiple scale signal matching (MSSM) [26,38] algorithm on a transporter [7,10,25,40] network. The MSSM algorithm is based on a multichannel vision model [35], to establish the correspondence between two images with the allowance that one of them can be deformed elastically. The MSSM algorithm uses a process consisting of two stages: the filtering and the matching stages. This process is iterated following a coarse-to-fine regime of the vision channels [35] at which the matching process is performed…

    Stability analysis of the static kramer drive
    (1996) Kesraoui, Mohamed
    The steady state analysis of the conventional static Kramer drive using three different of models, namely the DC, AC and DQ models is developed in the first part of thesis. The aim is to arrive at a correct prediction of the basic steady state characteristics of the drive through correlation of results of the different models used. This is motivated by the fact that most of the published work done on stability analysis of this drives relied on a wrong DQ steady state models. A correct DQ steady state model is established…

    A quasi-static analysis of MMIC transmission-line structures by the method of lines
    (1992) Issaoun, Ammar
    The current trends in both Monolithic Microwave Integrated Circuits (MMIC's) and High frequency digital circuits (HFDC's) are toward lower dimensions, higher circuit densities and increasing complexity. The corresponding CAD tools should take into consideration some circuit parameters that are currently...

    On the irreducible realization of rational transfer function matrices
    (1995) Yaici, Malika
    The problem of finding the minimal realization of a given transfer function matrix has been studied by several authors. it is to determine state variable realizations with the minimum possible number of states. the irreducible realization is useful in analog and digital computer simulation or operational amplifier circuit synthesis of the transfer function. irreducible realizations are desirable for reasons of economy and sensitivity…

    Nonparametric approach to digital image restoration
    (1995) Fadli, Djamel Eddine
    Image analysis is concerned with restoration and interpretation of images that have been contaminated by noise and possible some (nonlinear transformation). The purpose of our research work is to implemeent the statical nonparmetric methods to the restoration of noisy images which are charcterized by the range of possible values for the intensity function...

    Multivariable design via the solution of the lyapunov equation
    (1999) Amroune, Houria
    Relocating poles theory has been the subject of an important number of research studies. Using state feedback for this purpose is a widely used technique because of its simplicity and the quality of control achieved. the control signal is designed to be a function of the state and the reference signal. Controllability of an open-loop system is equivalent to the possibility of assigning anarbitrary set of eigenvalues to the closed-loop system's matrix by means of suitable linear feedback of the state…

    Multi-dimensional quasi-static analysis of MIC's and MMIC's
    (1994) Affane, Mahmoud
    Microwave Integrated Circuits (MIC's) and High Frecquency Digital Circuits (HFDC's) have reached a high degree of complexity arising essentially from increasing integrations levels and the use of multilayer parallel and crossing microstrip interconnections as well as arbitrary shaped metalizations on different interfaces of isotropic and anisotropic dielectric substrates

    MS-dosshell formal specifications
    (1994) Taibi, Mohammed
    The purpose of this research is to formalize (ie, using formal methods) an already existing human computer interface (dosshell) so as to provide a case study to encourage further research in the domain. The use of formal method in the specification of user interfaces has gained an increasing need in software development in the late eighties. Formal specifications are mathematical models representing computer systems. The use of mathematiques in software as hardware system development increases the system's reliability. Testability, ease of maintenance and cost effectiveness…

    Model reduction of MIMO systems
    (1991) Zabot, Hakim
    Over the past few decades, considerable imprvements have been made in the approximation of high degree multivariable systems by low degree reduced models. The resulting reduced models are used to simplify the analysis and synthesis of complex systems as well as their modelling and implementation...
