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 ...
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. ...
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 ...
Physical and mechanical properties of hemp fibre reinforced alkali-activated fly ash and fly ash/slag mortars
(Elsevier Ltd., 2020)
Two alkali-activated mortars with different solid prime materials were analysed. The first mortar contained fly ash, had lower density, higher water absorption, lower compactness, lower compressive strength, similar flexural ...
Structural response to axial testing of cold-formed stainless steel angle columns
(Thin-Walled Structures, 2020)
In this paper, the structural stability and compressive capacity of pin-ended cold-formed stainless steel angle columns with different slenderness were experimentally investigated. The experimental programme was performed ...
Design procedures for cold-formed stainless steel equal-leg angle columns
(Thin-Walled Structures, 2020)
Currently, there is still no explicit design approach for cold-formed stainless steel columns with equal-leg angle sections in Europe. A comprehensive numerical investigation, validated by the available experiments collected ...
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 ...
Span-to-depth ratio limits for deflection control of reinforced concrete elements
(Structural Concrete, 2022)
Indirect deflection control usually applies the limitation of the span-to-depth
ratio. The procedures that have developed in the past decades have mostly
been derived for predefined values of some of the relevant parameters. ...
Numerical simulation of Submarine non-rigid landslide by an explicit three-step incompressible smoothed particle hydrodynamics
(Elsevier, 2021)
Many landslides in nature may be classified as deformable landslides. The landslide volume is usually modeled as a rheological material when SPH methods are used for landslide simulation, since these methods allow for the ...
Behaviour of duplex stainless steel bolted connections
(Thin-Walled Structures, 2021)
This study deals with the behaviour of duplex stainless steel bolted connections. The aim of the study is torespond to the question if the current stainless steel design specifications are able to predict the behaviourof ...
