Stability Calculation of the Plane Steel Frame Structures Using Tangent Modulus Theory
(Hindawi, 2023)
This paper considers the phenomenon of the instability of steel plane frame structures in the elastic-plastic domain. The numerical analysis uses FEM, where the corresponding stiffness matrices are based upon the trigonometric ...
Intuitionistic Propositional Probability Logic
(Mathematical Logic Quarterly, 2022)
We give sound and complete axiomatization of a probabilistic extension of intuitionistic logic. Reasoning with probability operators, unlike other works on this topic, is also intuitionistic, that is, measure functions ...
On the Generalized Strongly Nil - Clean Property of the Matrix Rings
(World Scientific Publishing Company, 2021)
Let R be an associative unital ring and not necessarily commutative. We
analyzes conditions under which every n×n matrix A over R is expressible as a sum
A = E1 + ... +Es +N of (commuting) idempotent matrices Ei and a ...

Absolute Time Series GNSS Point Positioning-Data Cleaning and Noise Characterization
(Strojarski fakultet u Slavonskom Brodu, 2020)
Time series data of GNSS point positioning are considerably used for the purpose of geophysical research. The velocity estimates and their uncertainties derive from time series data of GNSS point positioning affected by ...
Construction cost estimation of reinforced and prestressed concrete bridges using machine learning
(Građevinar, 2021)
Seven state-of-the-art machine learning techniques for estimation of construction
costs of reinforced-concrete and prestressed concrete bridges are investigated in this
paper, including artificial neural networks (ANN) ...
Experimental investigation of preload losses in high strength bolts under cyclic loading
(GRAĐEVINAR, 2021)
Slip-resistant shear connections with preloaded bolts have traditionally been used in steel
structures exposed to cyclic. Hence, shear load is transferred through friction surfaces
rather than through contact between the ...
Determination of Mode I fracture properties of European spruce
(Wood Research, 2023)
In this paper an efficient procedure for obtaining a cohesive law for Mode I timber fracture (crack opening), based on the Double Cantilever Beam (DCB) tests is given. DCB tests were performed on ten European spruce specimens ...
Verification and Validation of an Advanced Guarded Hot Plate for Determination of Thermal Conductivity
(Society of Thermal Engineers of Serbia, 2022)
The guarded hot plate (GHP) method is a widely used technique to measure
thermal conductivity of thermal insulation specimens in steady-state conditions.
In this paper, an advance of GHP has been developed in the Laboratory ...
Short-term forecasting of PM10and PM2.5 concentrations with Facebook's Prophet Model at the Belgrade-Zeleno brdo
(Geofizika, 2023)
We demonstrate the use of Facebook's Prophet (usually just called Prophet) model for short-term air quality forecasting at Belgrade-Zeleno brdo monitoring station. To address missing data, we applied ...
