  • Végvári, Ferenc (Erdélyi Múzeum-Egyesület, 2009)
    Abstract Using of surface coated tools get more and more importance in metal forming technologies in the last years. Nowadays different kind of single- and multi-component nanocomposites are used as surface coating materials ...
  • Gulyás, Lajos; Fórián, Sándor; Kalmár, Tünde (Erdélyi Múzeum-Egyesület, 2009)
    Abstract A large part of technical operations are in connection with the flow and mixing of fluids. These processes are described by the equations of flow. The knowledge of laws of flow is very important for engineers, ...
  • Drégelyi-Kiss, Ágota; Hegedűs, László (Erdélyi Múzeum-Egyesület, 2009)
    Abstract In automative industry it is impotant to control the manufacturing process with the tools of quality statistics. There are such manufacturing processes (e.g. boring) where the widely used SPC tools are not ...
  • Varga, Gyula (Erdélyi Múzeum-Egyesület, 2009)
    Abstract In this paper the force model has been applied for estimate cutting forces at minimal quantity lubrication based on the cutting theory made by Oxley. The suggested model contains the lubricating and cooling effect ...
  • Pézsa, Nikolett; Trencséni, Balázs (Erdélyi Múzeum-Egyesület, 2009)
    Abstract Curb transport growth, increase energy efficiency and shift towards alternative fuels are possible ways to reduce oil dependency and CO2 emissions in the transport sector. On long term hydrogen seems to be the ...

    Abstract Our investigation would reveal which currently uncultivated plants might be cultivated successfully in Hungary in response to the predictable global warming. The changing climate of the Carpathian Basin favours ...
  • Réti, Tamás; Bitay, Enikő; László, István (Erdélyi Múzeum-Egyesület, 2009)
    Abstract In order to classify fullerene structures a new method based on the generation of local topological graph invariants is presented. In this study fullerenes are considered as trivalent bifaced polyhedra. The method ...
  • Pokorádi, László (Erdélyi Múzeum-Egyesület, 2009)
    Abstract The fuzzy set-theory is a very new mathematical tool to model inaccuracy of human thinking. Using fuzzy tools, the expert knowledge can be investigated and decision problems can be modeled and solved. The paper ...
  • Mankovits, Tamás; Szabó, Tamás; Juhász, György (Erdélyi Múzeum-Egyesület, 2009)
    Abstract This paper is concerned with the application of axially symmetric finite elements for the analysis of elastomers modeling with Neo-Hookean and Mooney-Rivlin materials. The penalty approach is applied for the ...
  • Ciortea, Elisabeta Mihaela; Baki-Hari, Zoltán-Gábor (Erdélyi Múzeum-Egyesület, 2009)
    Abstract The paper presents a shape recognition method used in order to identify the deviation from an imposed geometrical shape in the case of white products. This is the image binary binarization method. For white ...
