    Title: Knowledge - base for engineering design of electronic digital filters  Author: Mollova, Gergana Stoycheva Date: 1994 Abstract: A knowledge base, consisting of topological circuit structures and computational procedures is discussed. It is intended for computer-aided design of recursive digital filters. This knowledge base is an inherent part of a program system for engineering use. The data-transfer between the knowledge base unit and the other units of the system ... Library:

    Title: C - Realization of a real-to-complex conversion structure for radar signals  Author: Tchamova, Albena Plamenova Date: 1994 Abstract: Complex signals are discussed in digital signal processing for several reasons. In some cases the required processing can be made more efficiently using such kind of signal representation, in other cases the envelop, or phase of considered signal are of interest and it is suitable to extract them from complex data. It is a problem, closely ... Library:

    Title: Speeding up test generation for combinational digital circuits using transformations  Author: Roussev, Borislav Nickolov Date: 1994 Abstract: The theoretical study of Ibarra and Sahni [1] shows that test generation for combinational circuits is an NP-complete problem. The aim of the paper is to speed up the test generation for combinational circuits. The present exploration is inspired by the theory of Petri Nets [2]. A number of NP-complete analysis techniques for Place/transition ... Library:

    Title: Self-checking implementation of Boolean interpreted Petri nets  Author: Roussev, Borislav Nickolov Date: 1994 Abstract: This paper presents a technique of constructing a self-checking synchronous implementation of a Boolean Interpreted Petri Net. The validated Petri net specification is modeled with a circuit that automatically detects faults visible at Petri net level. The so called direct approach is used in modeling Petri nets by hardware. The faults that ... Library:

    Title: Fault simulators analysis using fault models refinement  Author: Georgicv, Ilia K. Date: 1994 Abstract: The main goal of this research activity is to estimate the matching between fault simulation methods and the need of fault models refinement. Long run times of exhausting simulation has been overcome by several methods: parallel, deduction, concurrent simulation, statistical simulation, hardware acceleration, etc. All these speeding-up ...

    Title: A study of the parallelism in some simulation algorithms for analog circuits and digital filters  Author: Konstantinova, Pavlina Dimitrova; Djerassi, Emanuil Nisim; Gadzheva, Elisaveta Dimitrova Date: 1994 Abstract: The basic analyses used for computer aided simulation of electronic circuits are frequency analysis, direct current analysis (DC) and transient analysis. Sensitivity analysis and symbolic analysis are also widely used. The requirements to the efficiency of all these kinds of analysis constantly increase and one of the ways to meet them is ... Library:

    Title: Industrial development officer engineering industries branch united nations industrial development organization  Author: Sratravko, Victor Date: 1994 Abstract: A mould or die design always starts from a product design This is inevitable since the product to be manufactured is the basis of the tool to be used for that purpose. Relevant production information such as material, producton volume, application and- strength, should be available. The design should facilitate uncomplicated production By ... Library:

    Title: Development of CAD - CAM system in "ELTOS" - JSC  Author: Radev, Ljobomir G. Date: 1994 Abstract: The company has been founded about 20 years ago, and its production was based on AEG technology. During the recent years, as a reply to the requirements of the international markets, the company has orientated its activity to smaller production series and wider range of products. A CAD - CAM system aiming to establish the unity between the ... Library:

    Title: Information systems technology: changes through the De CADES  Author: Mateev, Plamen Date: 1994 Abstract: The 1900e have emerged as a decade of radically changing business systems technology. Change, however, is not a new challenge of the 1990s. Businesses have faced evolutionary changes in information systems technology for over 40 years. In fact, there have been five eras of business computing Library:

    Title: Computer-aided analysis and diagnostics of analog and discrete electronic circuits  Author: Gadzheva, Elisaveta Dimitrova; Djerassi, Emanuil Nisim Date: 1994 Abstract: One of the principal trends in the computer-aided design (CAD) of electronic circuits is the improvement of the analysis methods and algorithms. The aim is to increase the speed and the accuracy of the analysis. Another important trend is the or¬ganization of programs and CAD systems which allow to use the algorithms in an easy and efficient ... Library:

    Title: Parallel techniques in Multimedia processing  Author: Georgiev, I. K.; Beltcheva, O. M.; Георгиев, И. К.; Белчева, О. М. Date: 1994 Abstract: The paper gives an analysis of the computational consuming subproblems that are objectives in the design of parallel algorithms. The complexity of these subproblems is well analyzed but the combination of several tasks in a complex system shows sometimes in effectiveness of the parallel realization. The most recently parallel techniques ... Library:
