  • Krajnyik, Károly; Nagy, Sándor; Péter, László (Erdélyi Múzeum-Egyesület, 2006)
    Abstract T-head screws are frequently used for fixing the workpiece during machining. Isotropic points can be generated in the screws. Positive isotropic points are dangerous because of arising of microcracks. We developed ...
  • Dudás, Illés (Erdélyi Múzeum-Egyesület, 2006)
    Introduction Greater and greater connection of science of metal cutting and economics can be noticed in the last years. Present reports [1] conclude, that necessary to integrate strongly technology and informatics (IT). We ...
  • Oláh, Erzsébet (Erdélyi Múzeum-Egyesület, 2006)
    Abstract To increase the agricultural production insecticides must be used but their residues in the environment cause some difficulties. For example the cypermethrin residues are fatal for fish at ppm level. Recent study ...
  • Lengyel, Antal; Peidl, László (Erdélyi Múzeum-Egyesület, 2006)
    Abstract The most harmful for the environment is the particle contained in the diesel engine’s exhaust gas. Its emitted quantity is determined by the loaded-up condition of the engine and the course of combustion. According ...
  • Miklósi, Péter (Erdélyi Múzeum-Egyesület, 2006)
    Abstract The increasing amount of end-of-life electrical and electronic products is a significant environmental problem. Many of them contains hazardous materials, therefore it is particularly important to find the adequate ...
  • Kovács, Mihály; Magyari, István (Erdélyi Múzeum-Egyesület, 2006)
    Abstract Main goal of this paper is to gather information about the electro active polymer’s response to an electrical stimulus, by mapping the procedure and creating a mathematical model for it. Electro active polymer ...
  • Schrempf, Norbert; Tóth, László (Erdélyi Múzeum-Egyesület, 2006)
    Summary In the practice of the utilization of wind energy, countless solutions of measuring technique are applied which, by the measurement principle also, are different. There is equipment emitting ultrasound (SODAR) or ...
  • Orbán, György (Erdélyi Múzeum-Egyesület, 2006)
    Abstract The n-dimensional geometric spaces in case of n>3 does’t can intuitiv interpretate. The geometry of this spaces has a perfect elaborated algebrical model. There are many calculations but they can effectuate easy ...
  • Kuzsella, László; Szabó, Imre (Erdélyi Múzeum-Egyesület, 2006)
    Abstract The wood is one of the most favourable structural material. It appears on all fields of the ordinary life. It is difficult to say an application where the wood is not used due to its cheap price, availability and ...
  • Csikja, Rudolf (Erdélyi Múzeum-Egyesület, 2006)
    Abstract A less known procedure is presented to investigate blow up in polynomial ordinary differential equations. First, solutions to linear and nonlinear ─ more precisely: polynomial ─ equations are compared with respect ...
  • Mezei, Sándor (Erdélyi Múzeum-Egyesület, 2006)
    Summary Group technology can also be used in case of working on semiautomatic turning-lathe. We select the groups of pieces so that the fixing dimensions be close to one another. We solve the diameter differences by ...
  • Szűcs, András; Pósa, Márk (Erdélyi Múzeum-Egyesület, 2006)
    Abstract Many interdependent parameters must be controlled during injection mounding process to produce the proper quality product. Any external action can cause the quality changing of injected products (e.g. mechanical ...
  • Szász, Zoltán Elemér; Szilágyi, Sándor Miklós (Erdélyi Múzeum-Egyesület, 2006)
    Abstract Nowadays the biomedical engineering is one of the most evolving research fields. Due to the complexity of the biological processes the various signal processing directions tends toward stochastic analysis. This ...
  • Iclănzan, David (Erdélyi Múzeum-Egyesület, 2006)
    Abstract Genetic algorithms (GA) have several important key features, like parallel processing, the ability to work with highly nonlinear, noisy systems, tolerance for imprecision, uncertainty and partial truth etc. that ...
  • Kovács, Tünde; Barányi, István; Dévényi, László (Erdélyi Múzeum-Egyesület, 2006)
    Abstract When investigating the wear phenomena often there is a need for studying the wear process on the basis of variable parameters (microstructure, surface roughness, and load). A new experimental method was developed ...
  • Varró, Gergely (Erdélyi Múzeum-Egyesület, 2006)
    Abstract An overview on the paradigm of graph transformation is given, which can be used for a rule-based description of simulations. The specification tasks that are necessary to quantitatively compare the run-time ...
  • Dudás, Illés; Felhő, Csaba (Erdélyi Múzeum-Egyesület, 2006)
    Abstract Nowadays Rapid Prototyping technologies are extensively known and used at production design. As special manufacturing processes today these technologies got emphasis at production of functional parts. However the ...
  • Baki-Hari, Zoltán-Gábor (Erdélyi Múzeum-Egyesület, 2006)
    Abstract This work deals with the possibilities to improve the quality of Rapid Prototyping (RP) models. Firstly, the RP applications and the quality parameters of the RP models have been concisely presented. At the end, ...
  • Decsi, Tamás (Erdélyi Múzeum-Egyesület, 2006)
    Abstract The Hungarian power network is loaded with significant transit due to the opening of the European electicity market and the geographical locality of the Hungarian power network. The border crossing flows’ forecast ...
  • Oláh, Béla; Bányai, Tamás; Cselényi, József (Erdélyi Múzeum-Egyesület, 2006)
    Abstract The events that led up to this scientific work that the detailed in the former publications analysis of assignment algorithms of assembly plants to the final product requirements of the end users in a cooperative ...
