  Cutting elements of bucket wheel excavators in lignite opensast mines: Methodology and performed solutions cite

  Dragan Novaković, Predrag Jovančić (2016)

  Bucket and cutting elements geometry (teeth and hardened steel) have very powerful impact on effective operation of bucket wheel excavator, and that`s why, problems of optimal geometry of elements in specific conditions always are of special interest in mining science and technique. If we want to achieve satisfactory utilization of bucket wheel excavator, it is necessary to modulate geometry material characteristics and technological parameters, as regards bucket wheel excavator work regime, and bucket wheel working performances, and also bucket ...

  Примена CNC машина при обради мермера cite

  Ненад Остојић (2024)

  Мермер је стена настала метаморфизмом седиментних карбонатних стена, најчешће кречњака или доломита. Мермер се углавном састоји од калцита,кречњака, серпентина и доломита. Његове главне компоненте су углавном калцијум карбонат, који чини више од 50 посто, и други магнезијум карбонат, калцијум оксид, манган оксид и силицијум диоксид, итд. Фазе обраде мермера су: примарно резање мермерних блокова у плоче, површинска обрада мермерних плоча, секундарно резање мермерних плоча, терцијарна обрада (ако је потребно). CNC машина је електро-механички уређај који управља алатима, користећи програмирање путем ...

  Some continuous stress mixed formulations and inf-sup test cite

  Mladen Berković, Dubravka Mijuca, Ines Grozdanović (2001)

  The most frequent motivation for the use of mixed methods is their robustness in the presence of certain limiting and extreme situations. At variance, the main goal of the present paper is to reconsider the use of mixed formulation as a tool for wider application, i.e., to study the stability of the proposed procedure treating problems in elasticity otherwise well suited for the solution by the usual displacement method.Computational procedure for the inf-sup test is outlined, and the results ...

  On the distribution modulo 1 of the sum of powers of a Salem number cite

  Dragan Stankov (2016)

  It is well known that the sequence of powers of a Salem number θ, modulo 1, is dense in the unit interval, but is not uniformly distributed. Generalizing a result of Dupain, we determine, explicitly, the repartition function of the sequence , where P is a polynomial with integer coefficients and θ is quartic. Also, we consider some examples to illustrate the method of determination.

  Characterization of biochar surface functional groups cite

  Marija Ilić, Vesna Pavelkić, Aleksandar Lolić, Branko Leković (2021)

  In this work, biochar originating from paper fibres was examined. Biochar was prepared via pyrolysis method at 550°C. Oxygen-containing functional groups on biochar surface were determined. The surface functional groups of biochar were analysed by Fourier transform infrared spectroscopy. The amount of oxygen-containing functional groups was performed with Boehm titration. The total acidity of biochar was mostly attributed to carboxylic and lactonic groups.
