Title:A cryptographic handshaking in database: algorithm for a distributed system
Author:Arnaudov, Dino; Noninska, IrinaDate:1994Abstract:The paper presents a cryptographic algorithm, designed for handshaking before message sending in a distributed database system (DDBS). Using this algorithm it is possible to authenticate both - sender and receiver of a message. The algorithm designed does not depend on main cryptographic algorithm, used for enciphering and deciphering in the secret systemLibrary:

Title:The use of knowledge-based configuration system technology for PCs
Author:Patias, Yannis; Momchev, IvanDate:1994Abstract:Knowledge-based systems in system development life cycle. There are three major ways of building computer-based information systems. They are transaction processing systems (TPS), decision support systems (DSS), and knowledge-based systems (KBS) [1].
TPSs perform routine data processing, are designed around forms, procedure inputs,, and ...Library:

Title:Propagation of real fluid in tubes. Flow induced vibrations models of Chen a Paidoussis
Author:Yoshinov, R.Date:1994Abstract:Investigation of flow induced vibrations caused by fluid propagation in tubes dates from 1958. This relies on the fact that lateral amplitudes of deflection caused by this propagation are small (1/1000 - 1/10 sm.). They should be ignored if there were not many cases in practice where even these small amplitudes of oscillation are dangerous. ...Library:

Title:Sensitivity analysis of recursive spiral-like digital filters
Author:Petrova, Petrana AngelovaDate:1994Abstract:In this paper the main elements of sensitivity analysis of recursive filters with spiral-like structure are discussed. An effective method for state space structure description is suggested. This method allows the automation of state matrix element determination. The sensitivity measures characterizing the filter structure are defined. A ...Library:

Title:Minimum word length determination of two-dimensional digital filters
Author:Petrova, Petrana AngelovaDate:1994Abstract:In this paper an approach for minimum word length determination guaranteeing the stability of a specified two-dimensional digital filter (TDF) is suggested. For this purpose a state-space filter description is used. The stability condition of the TDF is brought to two single-dimension stability conditions. The lower bound of the machine ...Library:

Title:Thermodynamic properties of real working mediums for conventional artillery weapons
Author:Danov, Stanislav; Vassilev, DanielDate:1994Abstract:The thermodynamic behavior of gases from the gunpowder-burning is described by the Redlich-Kwong’s equation of state, valid for real gases under high pressure and temperature. Mathematical dependencies between thermal parameters (P, T, v) and caloric parameters (u, i, cp, cv) have been obtained. That enables us to create a mathematical model ...Library:

Title:Correlation diagrams for prognosis and optimization of semiconducting ore minerals flotation
Author:Baev, Ivan Alexandrov; Panayotov, Vladko TodorovDate:1994Abstract:The flotation ability of semiconducting ore minerals depends essentially on the mineral surface state end properties. It was shown in [1] that the preliminary treatment of the semiconducting minerals galena, chalcopyrite and sphalerite in gas medium (ozone) leads to a significant improvement of the flotation yield. On the other hand, the ...Library:
