Has the latest global financial crisis changed the way road public-private partnerships are funded? A comparison of Europe and Latin America
(Elsevier, 2020)
A financial/economic crisis may have an adverse effect on transport public-private partnerships (PPPs) as both traffic demand is negatively influenced, and governments are further under pressure. However, research on awarded ...
The role of service life in Life Cycle Assessment of concrete structures
(Elsevier Ltd, 2020)
In comparative Life Cycle Assessment (LCA) of concrete structures it is of crucial importance to provide the functional equivalence of compared alternatives. Most commonly, the comparison is performed between the structures ...
Dynamic stiffness – based free vibration study of open circular cylindrical shells
(Elsevier, 2020)
In this paper, the dynamic stiffness method has been applied in the free vibration analysis of open circular cylindrical shells based on Flügge thin shell theory. The dynamic stiffness matrix for a completely free open ...
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. ...
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 ...
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 ...
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 ...
Weighted quasisymmetric enumerator for generalized permutohedra
(Springer, 2020)
We introduce a weighted quasisymmetric enumerator function associated to generalized permutohedra. It refines the Billera, Jia and Reiner quasisymmetric function which also includes the Stanley chromatic symmetric function. ...
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 ...
