Chebyshev polynomials and r-circulant matrices
(Applied Mathematics and Computation, 2022)
This paper connects two attractive topics in applied mathematics, r-circulant matrices and the
Chebyshev polynomials. The r-circulant matrices whose entries are the Chebyshev polynomials
of the first or second kind are ...
Wastewater-based epidemiology in countries with poor wastewater treatment — Epidemiological indicator function of SARS-CoV-2 RNA in surface waters
(Elsevier B.V., 2022)
Wastewater-based epidemiology (WBE) surveillance of COVID-19 and other future outbreaks is
a challenge for developing countries as most households are not connected to a sewerage system.
In December 2019, SARS-CoV-2 RNA ...
On the extension of the Erdös-Mordell type inequalities
(Mathematical Inequalities & Applications, 2014)
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Faktori interakcije šipova u grupi pod dejstvom horizontalnog opterećenja proizvoljnog pravca
(Građevinski Kalendar, 2021)
Konstrukcije vetroturbina, mostova, industrijskih dimnjaka, potpornih zidova i sl. mogu biti izložene značajnim horizontalnim opterećenjima iz različitih izvora. Ove konstrukcije su često fundirane na grupama šipova. Efekti ...
An Adaptive Fiber Section Discretization Scheme for Nonlinear Frame Analysis
(American Society of Civil Engineers, 2022)
The paper proposes an adaptive fiber section discretization scheme for inelastic frame elements. The scheme uses cubature rules for the efficient and accurate evaluation of the section response over the elastic portion of ...
Methods for Life Extension of Multi-Storey Car Park Buildings
(Taylor and Francis, 2022)
Multi-storey car park buildings with steel–concrete composite floor structures are widespread in construction due to the distinct benefits of the implemented structural system. Although there are various possibilities for ...
Flexural behaviour and ultimate bending capacity of high-volume fly ash reinforced concrete beams
(Engineering Structures, 2023)
Large number of studies analyzed physical and mechanical properties of high-volume fly ash concrete, but only a few discussed its structural behavior. Material properties are an important input parameter for structural ...
Long-term behaviour of reinforced beams made with natural or recycled aggregate concrete and high-volume fly ash concrete
(Elsevier, 2018)
Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high-volume fly ash concrete ...
Shear behaviour of recycled aggregate concrete beams with and without shear reinforcement
(Engineering Structures, 2017)
An experimental study of the shear behaviour of recycled aggregate concrete (RAC) beams with and without shear reinforcement is presented. Nine full-scale simply supported beams were loaded in four-point bending tests until ...
Some considerations of urban drainage design practice using experimental data
(Atmospheric Research, 1996)
Two
most frequently used procedures for obtaining design flow rates in urban drainage
practice are design storm approach and historical storm approach. An alternative approach
is possible if a series of ...
