On a generalized Jordan normal form of an infinite upper triangular matrix
(Taylor & Francis Ltd, United Kingdom, 2019)
Any square matrix over an algebraically closed field has a Jordan normal form. In this paper, we prove that every infinite upper triangular matrix over an arbitrary field has a generalized infinite Jordan normal form.
Vertical Vibrations of Rectangular Flexible Foundation on Viscoelastic Halfspace
(Scientific Journal of Civil Engineering (SJCE), 2019)
This paper presents a novel method, ITM- DSM, for the soil-foundation interaction problems analysis. It is a semi-numerical method based on the coupling of the Integral Transform Method (ITM) and the Dynamic Stiffness ...
GNSS and SAR Signal Delay in Perturbed Ionospheric D-Region During Solar X-Ray Flares
(IEEE (Institute of Electrical and Electronics Engineers), 2019)
We investigate the influence of the perturbed (by a solar X-ray flare) ionospheric D-region on the GNSS and SAR signals. We calculate a signal delay in the D-region based on the low ionospheric monitoring by very low ...

Image Processing for Hydraulic Jump Free-Surface Detection
(IAHR, 2019)
Hydraulic jumps exhibit a high degree of free-surface oscillations, triggered by intense turbulence and aeration.
These processes are difficult to model numerically and are frequently investigated on a scale model. ...
Geometrical, Fresnel, and Fraunhofer Regimes of Single-Slit Diffraction
(American Association of Physics Teachers - AAPT.org, 2019)
Recently, Panuski and Mungan presented the results of their study of light diffraction from a variable-width single slit by observing and measuring the diffraction pattern on an observation screen placed at a fixed distance. ...

Relevant Properties of Green Self-Compacting Concrete
(Institute for Multidisciplinary Research, University of Belgrade, 2019)
The production of durable concrete with a high content of supplementing cementitious materials and recycled aggregate presents a step towards sustainability in the concrete industry. The paper presents the findings of the ...
Vibrations of Massless Flexible Strip on Visco-Elastic Half-Space
(7th International Congress of Serbian Society of Mechanics, 2019)
This paper deals with the analysis of the dynamic response of the flexible strip foundation resting on the surface of the soil. Plane strain steady state analysis is considered. The cross section of the foundation behaves ...
Model for practical carbonation depth prediction for high volume fly ash concrete and recycled aggregate concrete
(Elsevier, 2019)
The reuse of industrial residue streams such as fly ash (FA) or waste materials such as recycled concrete aggregate (RCA) can be beneficial both from an economic and an ecological point of view. Extensive research, ...
