Investigating the effect of novel self-lubricant TiSiVN films on topography, diffusion and oxidation phenomenon at the chip-tool interface during dry machining of Ti-6Al-4V alloy
(Elsevier, 2023-08)
Machining of titanium alloys such as Ti-6Al-4 V can be very intimidating due to their low thermal conductivity leading to elevated cutting temperatures at the chip-tool interface (ICT). In this regard, the self-lubrication ...
Fabrication and characterization of active polymer optical fibers with a ring-doped structure
(Elsevier, 2023-01)
This paper employs the solution-doping technique for the fabrication of polymer optical fibers (POFs) doped with two perylene derivatives, Lumogen Yellow 083 and Lumogen Red 305, in different combinations. With the ...
Biomarker responses in mussels (Mytilus trossulus) from the Baltic Sea exposed to water-accommodated fraction of crude oil and a dispersant at different salinities
(Elsevier, 2023-07)
Oil spills pose significant environmental risks, particularly in cold seas. In the Baltic Sea, the low salinity (from 0 to 2 up to 18) affects the behaviour of the spilled oil as well as the efficiency and ecological impacts ...
CNN based facial aesthetics analysis through dynamic robust losses and ensemble regression
(Springer, 2023-05)
In recent years, estimating beauty of faces has attracted growing interest in the fields of computer vision and machine
learning. This is due to the emergence of face beauty datasets (such as SCUT-FBP, SCUT-FBP5500 and ...
Single-ended limiting inductor voltage-ratio-derivative protection scheme for VSC-HVDC grids
(Elsevier, 2023-05)
Single-ended protection systems present the characteristics needed to fulfil the restrictive speed requirement related to high voltage direct current grids. This paper proposes a novel single-ended protection algorithm ...
The Intramolecular Povarov Tool in the Construction of Fused Nitrogen-Containing Heterocycles
(Springer, 2023-06)
Nitrogen heterocycles are part of the structure of natural products and agents with
important biological activity, such as antiviral, antibiotic, and antitumor drugs. For
this reason, heterocyclic compounds are one of ...
Robust oscillator-mediated phase gates driven by low-intensity pulses
(Nature, 2023)
Robust qubit-qubit interactions mediated by bosonic modes are central to many quantum technologies. Existing proposals combining fast oscillator-mediated gates with dynamical decoupling require strong pulses or fast control ...
An integer programming model for obtaining cyclic quasi-difference matrices
(Elsevier, 2023)
Orthogonal arrays are of great importance in mathematical sciences. This paper analyses a certain practical
advantage of quasi-difference matrices over difference matrices to obtain orthogonal arrays with given
parameters. ...
Data driven model for heat load prediction in buildings connected to District Heating by using smart heat meters
(Elsevier, 2022-01-15)
[EN] An accurate characterization and prediction of heat loads in buildings connected to a District Heating (DH) network is crucial for the effective operation of these systems. The high variability of the heat production ...
Evaluation of a crop rotation with biological inhibition potential to avoid N2O emissions in comparison with synthetic nitrification inhibition
(Elsevier, 2023-05)
Agriculture has increased the release of reactive nitrogen to the environment due to crops' low nitrogen-use efficiency (NUE) after the application of nitrogen-fertilisers. Practices like the use of stabilized-fertilisers ...
