Fast data assimilation for open channel hydrodynamic models using control theory approach
(Elsevier, 2020)
Model-driven forecasting, used for flood risks or big hydropower systems management, can produce results of unsatisfying accuracy even with best-calibrated hydrodynamic models. One of the biggest uncertainty sources is the ...
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 ...
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.
Horizontal coordinates transformation and residuals modelling on the territory of the Republic of Srpska
(Taylor & Francis, 2020)
The paper describes the optimal model for coordinate transformation between ETRS89 and old national reference system in the Republic of Srpska. The Helmert`s parameters were estimated, based on a set of 1 741 common points. ...
Numerical study of vibrations induced by horizontal-axis wind turbine on a steel building
(Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2019)
One of the most important acceptance issues regarding the implementation of small-scale wind turbines in urban environments is related to human comfort. Turbine-induced vibrations can have a large influence on small-scale ...
Quantitative assessment of the parameters linked to the blending between reclaimed asphalt binder and recycling agent: A literature review
(Elsevier, 2020)
The lack of understanding the mechanisms governing the interaction between reclaimed asphalt binder (RAb)1 and recycling agents is one of the technical issues that still need to be resolved when high amount of reclaimed ...
Evaluation of Concrete Cover Depth for Green Concretes Exposed to Carbonation
(John Wiley & Sons Ltd, 2020)
Carbonation resistance of fly ash concrete (FAC) and recycled aggregate concrete (RAC) has been extensively tested in the past decade, but there are still no recommendations for their application in codes of practice. ...
The clean graph of a commutative ring
(Charles Babbage Research Centre, 2017)
To gain a better understanding of clean rings and their relatives, the clean graph of a commutative ring with identity is introduced and its various properties established. Further investigation of clean graphs leads to ...
The line graph associated to the total graph of a commutative ring
(Ars Combinatoria, 2016)
Let R be a commutative ring with identity and T(Gamma(R)) its total graph. The subject of this article is the investigation of the properties of the corresponding line graph L(T(Gamma(R))). The classification of all ...
Image processing for hydraulic jump free-surface detection: coupled gradient/machine learning model
(IOP, 2020)
High-frequency oscillations and high surface aeration, induced by the strong turbulence, make water depth measurement for hydraulic jumps a persistently challenging task. The investigation of the hydraulic jump behaviour ...
