  Approximation of the number of roots that do not lie on the unit circle of a self-reciprocal polynomial cite

  Dragan Stankov (2024)

  We introduce the ratio of the number of roots not equal to 1 in modulus of a reciprocal polynomial Rd(x) to its degree d. For some sequences of reciprocal polynomials we show that the ratio has a limit L when d tends to infinity. Each of these sequences is defined using a two variable polynomial P(x,y) so that Rd(x) = P(x,xn). For P(x,y) we present the theorem for the limit ratio which is analogous to the Boyd-Lawton limit formula ...

  The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers cite

  Dragan Ignjatović, Predrag Jovančić, Stevan Đenadić, Ivan Janković, Ivica Ristović (2019)

  One of the most important prerequisites for the successful operation of the open-cast lignite mine is to carry out all the auxiliary works timely with the necessary quality. The most important and most commonly used auxiliary machines are bulldozers. Engaging time of bulldozers use is in direct relation with the coefficients of the time and capacity utilization of the continuous system for the excavation of coal and tailings, which indicates their importance. More than 100 bulldozers have been hired ...

  Контрола збијености природног тла (у ископу) или збијеног у насипу при изградњи саобраћајница представља један од основних облика контроле квалитета доњег строја. Код изградње брзих саобраћајница (аутопутеви и брза железница) приоритет је постизање високог нивоа контроле извршених радова. У циљу онемогућавања диференцијалног слегања (при изградњи насипа), или промене запремине услед допунског збијања материјала, које неминовно доводе до деформација, потребно је извршити оптимално збијање материјала. У оквиру овог рада приказује се техничка регулатива која регулише контролу збијености при изградњи железничке ...

  We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...

  Ovaj rad ima primarni cilj da definiše modernizaciju i revitalizaciju pogonske grupe rotora bagera SRs 2000 kako bi se obezbedilo povećanje pouzdanosti bagera, a time i povećanje vremenskog i kapacitetnog iskorišćenja i smanje troškovi održavanja. Sekundarni cilj, i ne manje važan, je unifikacija elemenata kako pogonske grupe tako i ostalih sklopova predviđenih za buduću modernizaciju i revitalizaciju na svim bagerima SRs 2000 koji rade na površinskim kopovima Elektroprivrede Srbije.
