    CALCULATION OF THE MAIN ENERGY CHARACTERISTICS OF PLANT STEAM TURBINES WORKING ON THE CLAUSIUSRANKINE CYCLE WITH REHEATING
    (University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2016) Vučinić, Radivojka; Srđan, Pelkic; Krstova, Keti; Đurić, Aleksija
    Through this work is shown the calculation procedure for the main energy characteristics of plant steam turbines working on the Clausius-Rankine cycle with reheating. The parameters that we are going to analyze are the level of usefulness ηPPT, specific heat consumption qPPT, total and specific steam consumption MTVPu, mPPT and the unit useful work LiTeq . This project was developed for maximum continuous power turbines of 235 MW, all the other parameters that were used in the calculation are listed in the the work. The aim of this research is to show the comprehensive budget mentioned turbines and making the schematic operation of the system with calculated characteristics, which could be used as a good basis for the design of thermal power plants.

    DEVELOPMENT OF NEW PRODUCTS IN INDUSTRY OF UPHOLSTERD FURNITURE
    (University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2015) Pelkić, Srđan; Đurić, Aleksija; Marković, Biljana; Vučinić, Radivojka
    This paper presents the development phases of new products in the upholstered furniture industry, ranging from market research to mass production. During the development of the new products, teams od experts from various fields are included, such as: mechanical engineering, chemistry, architecture, economics, which has been discussed in this paper. Also, for preparation of this paper has been used CAD/CAM technology, without which is unthinkable to develop new products today. The emphasis, during the development of new product, is put on flexibility of product, price, quick and simple installation, improvement of productivity, materials, environmental standards and specifications, transport and packaging, marking and identification of products in stock, technical documentation, making the zero batch and, at the end, batch production, i.e. at all stages and elements essentials for the development of new products, which target is competitiveness in the market of upholstered furniture.
