Item Task partition based parallel design and implementation of the MSSM algorithm on network of transputers(1995) Cheref, MohamedThe 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…Item On the irreducible realization of rational transfer function matrices(1995) Yaici, MalikaThe 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…Item Multivariable design via the solution of the lyapunov equation(1999) Amroune, HouriaRelocating 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…Item Design and implementation of a parallel wavelet transform algorithm using unity model and systolic arrays(1997) Yahiaoui, AichaIn the past two decades, there has been a tremendous progress in the development and analysis of parallel programs for different applications. Since the time required to solve a problem by a traditional computer is significantly reduced when using a parallel computer, we worked on the design and analysis of a parallel algorithm to solve the wavelet transform because the analysis and synthesis using wavelets has became a very useful tool for analyzing non-stationary signals in completion of the windowed Fourier transform which is the most known time-frequency representation…
