    Logic Circuits With High-Impedance Output State For Interconnection Of Ternary And Binary CMOS Digital Circuits And Systems
    (2012) Bundalo, Dušanka; Bundalo, Zlatko; Softić, Ferid; Kostadinović, Miroslav; Pašalić, Dražen
    Possibilities and principles for interconnection of CMOS ternary circuits and systems with binary common buses in digital circuits and systems are considered and described in the paper. Proposed are circuits with highimpedance output state for interconnection that perform signal conversion from ternary to binary CMOS digital system. General structure and general principle for design of such circuits are shown and described first. Then, the concrete circuit solutions are proposed and described. The circuits with one ternary input and the circuits with any number of ternary inputs are given and described. All proposed circuits were analyzed by computer simulations. All considerations, descriptions and conclusions were confirmed by simulation.

    Model of Hybrid Electric Vehicle with Two Energy Sources
    (MDPI, 2022) Brtka, Eleonora; Jotanović, Gordana; Stjepanović, Aleksandar; Jausevac, Goran; Kosovac, Amel; Cvitić, Ivan; Kostadinović, Miroslav
    The paper proposes a Hybrid Electric Vehicle (HEV) design based on the installation of a fuel cell (FC) module in the existing Daewoo Tico electric vehicle to increase its range in urban areas. Installing an FC module supplied by a 2 kg hydrogen tank would not significantly increase the mass of the electric vehicle, and the charging time of the hydrogen tank is lower than the battery charging time. For design analysis, a model was created in the MATLAB/Simulink software package. The model simulates vehicle range at different HEV speeds for Absorbent Glass Mat (AGM) and Proton Exchange Membrane Fuel Cell (PEMFC) power sources. The greatest anticipated benefit derived from the model analysis relates to velocities ranging from 20 km/h to 30 km/h, although the optimal HEV velocity in an urban area is in the range of 30 km/h to 40 km/h. The results indicate that this conversion of Electric Vehicle (EV) to HEV would bring a benefit of 87.4% in terms of vehicle range in urban areas. Therefore, the result of the conversion in this case is a vehicle with sub-optimal characteristics, which are nevertheless very close to optimal.

    Planning and Management of WirelessHart Network
    (Institute of Electrical and Electronics Engineers (IEEE), 2010) Kostadinović, Miroslav; Bundalo, Dušanka; Bundalo, Zlatko
    Wireless networks are very often used in the process industry. One of such networks is the WirelessHart network. The planning and management of the WirelessHart network in the process industry is considered and described in this paper. In order to analyze behavior of the WirelessHart network in the process industry in the paper are first described devices that are used in the network, the gateway and the transmitters. Then the results of simulation for planning and managing of execution of the communication in the network using AMS Wireless Configurator and SNAP-ON application are presented.
