Energy Potential of Non-Wood Biomass in Serbia
Limited resourses of fosil fuels and the greenhouse effect imposed a need for constant researches in area of usage of renewable energy sources (RES) a long time ago. Goal of this researches is using renewable energy sources more often. One of the types of renewable energy sources in Serbia is nonwood biomass. Nonwood biomass has two big advantages....

Investigating the operation of a turbidimeter for monitoring the turbidity of water at the water intake
The operational definition of water turbidity is an important step in checking the quality of drinking water. In this work an analysis of existing methods and systems of operational control of turbidity of water was carried out, and design of turbidimeter consisting of a two-channel sensor (measuring and reference channels) and a measuring device (...

Computer modeling of the scanning signal to detect metallic inclusions in raw materials
Modern technological processing various bulk materials provide high requirements for the quality of input raw materials. As practice shows, penetration of metallic inclusions in the raw material takes place during its extraction and during the passage of individual cycles of the technological process and leads to low quality of the output products,...

Component-oriented modelling of dynamical systems in Python language on the example of the model of the sucker rod string
The principles of component-oriented hybrid modelling of complex dynamical systems based on the Python language and its SymPy and SciPy libraries have been proposed. The Python-classes that allow you to create the models in Python without the need to study and apply specialized modelling languages have been developed. These classes can also be used...

BIOT-SAVART Law Application in Wireless Power Transfer – Dependence of Magnetic Field to Angle Position
The magnetic field of a closed loop of conductive wire can be computed due to Biot-Savart law, which analyses the value of the field at an exterior point from the transversal axis. If the measure point is out of the axis then the magnetic field has completely different values. A general stated form of this law can measure the value in any point, in...

Nonlinear boundary value problems arising in chemical reactor theory
In this article we obtain some numerical results for the considered problem u'' - u' + (-u^2 + 1)e^(-1/(1+u)) = 0 on [0,1] u'(0) - u(0) = 0u'(1) = 0 This problem arises from the theory of adiabatic tubular chemical reactors. To solve the problem from above we applied a common fixed point result for non-deceasing and weakly increasing operators i...
