Item Model reduction of MIMO systems(1991) Zabot, HakimOver 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...Item A microprocessor-based multiplexed system for automotive industry(1991) Meghriche, KamalThere are many applications where modern control system are becoming more and more sophisticated with a resultant increase in the complexity of wiring interconnections. This complexity is due to the requirement of one or more conductors to connect the control panel to each specitified function. these connectors are to carry power, control and monitoring signals to remote locations…Item A microprocessor-based crane load state monitoring system(1991) Benazzouz, DjamelThe objective of this research work is to develop a microprocessor-based system to monitor the load stat and insure the safety of a mobile telescopic crane. The need for an automatic and intelligent system that determines the lifted lead, in replacement to the exiting design based on analog electronics, is to serve the national crane manufacturing company ENMTP-CPG, Ain-Smara, Algeria. The conventional microprocessor-based system use the searching technique( look-up tables) to read the allowed load stored in memory…Item Algorithms for the factorization of matrix polynomials(1992) Dahimene, AbdelhakimThe factorization (root finding) of scalar polynomials is an important tool of analysis and design for linear systems. This thesis is a part of an ongoing effort to generalize these tools to multivariable systems via the factorization of matrix polynimials. The main contribution of this thesis can be summarized as follows...Item A quasi-static analysis of MMIC transmission-line structures by the method of lines(1992) Issaoun, AmmarThe 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...Item Effect of frequency on the substrate current in MOS devices(1992) Benfdila, ArezkiItem Density distribution of mobile ions in the oxide of MOS structures(1992) Bentarzi, HamidThe present work aims to study the mobile ion distribution in the oxides of MOS structures. The subject is introduced with the necessary background concept of MOS structure dealing with various aspects of oxid and its charges. A review is then...Item Charge-extraction technique for studying the surface-states in MOS devices(1992) Bouderbala, RachidItem Étude des caractéristiques d'irrégularité du fil de coton cardé(1993) Iguedad, AmarItem Contribution à l'étude des paliers de moteurs thermiques en régime transitoire(1994) Rachedi, KamelItem MS-dosshell formal specifications(1994) Taibi, MohammedThe 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…Item A model based formal specification of a medical expert system(1994) Azni, MohamedIn this thesis, the problem of the specification of the reasoning processes that are used in the development of the systems is investigated, and a specification model of a medical expert system is proposed. Traditionally, expert systems are developed by following an exploratory programming model of the software life-cycle. In this model of software development, the developer progresses towards the desired system by building an initial implementation, and gradually, refilining it into working prototypes,…Item Statistical smoothing methods for stationary random signals(1994) Boucheta, RachidItem Multi-dimensional quasi-static analysis of MIC's and MMIC's(1994) Affane, MahmoudMicrowave 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 substratesItem Computer aided medical training system(1994) Imache, Rabah
