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 ...
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 ...
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. ...
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. ...
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 ...
Column Curves for Stainless Steel Lipped–Channel Sections
(Journal of Structural Engineering, 2020)
The strength of thin-walled stainless steel columns has been investigated extensively over the last few years. The present paper presents the results of an extensive computational study of the buckling strength of ...
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 ...
Behaviour of stainless steel plain channel section columns
(Thin-Walled Structures, 2020)
In this paper, the structural stability of cold-formed stainless steel plain channel columns under axial compression is investigated. Reliable finite element models for channel section columns are first ...
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 ...
