Thermal aging management for electricity distribution networks: FEM-based qualification of underground power cables
(Thermal Science, 2022-03)
It is well-known that there is no PLAN-DO-CHECK-ACT (PDCA) approach that is used by electricity distribution network operators and asset managers of power cable systems. Accordingly, this paper proposes a novel application ...
Increasing the ampacity of underground cable lines by optimising the thermal environment and design parameters for cable crossings
(IET Generation, Transmission & Distribution, 2022-02-28)
The problem of optimising the thermal environment and design parameters of under-ground cable lines for cable crossings with the aim of increasing the ampacities of cablesis considered in this paper. Particle swarm ...
Study of thermal properties and microstructure of the Ag–Ge alloys
(JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY, 2022)
Microstructure, phase transitions and thermal properties including thermal diffusivity and thermal conductivity of four Ag–Ge alloys with 20, 40, 60 and 80 at % of Ge were experimentally investigated in this study. Observation ...
Microstructure and thermal properties of the Bi–Ag alloys
(Journal of Thermal Analysis and Calorimetry, 2022)
Microstructure, melting behavior and thermal conductivities of three Bi–Ag alloys with 5, 20 and 45 mass% of Ag were experimentally studied in the present work. Phase morphology of the alloys was analyzed by the light ...
Thermodynamic description and electrical conductivity of the Ge-In-Zn system: Experiments and modeling
(Calphad, 2022-06)
The ternary Ge-In-Zn system is chosen for the study due to the importance of germanium-based alloys in the industry of electronic devices and their special application as memory materials. This ternary system has not been ...
Experimental Study of the Phase Equilibria in the Ternary Ga-Ge-Zn System
(Journal of Phase Equilibria and Diffusion, 2022-04)
In the current study the ternary Ga-Ge-Zn system was experimentally and analytically tested. The ternary system is chosen due to the importance of germanium-based alloys in the electronic industry and their special application ...
The Effect of Material Heterogeneity and Temperature on Impact Toughness and Fracture Resistance of SA-387 Gr. 91 Welded Joints
(Materials, 2022-03)
This paper presents the analysis of the behavior of welded joints made of 9–12% Cr-Mo steel SA-387 Gr. 91. The successful application of this steel depends not only on the base metal’s (BM) properties but even more on ...
Nonlinear Vibration of a Nonlocal Functionally Graded Beam on Fractional Visco-Pasternak Foundation
(Nonlinear Dynamics, 2022)
This paper investigates the nonlinear dynamic behavior of a nonlocal functionally graded Euler–Bernoulli beam resting on a fractional visco-Pasternak foundation and subjected to harmonic loads. The proposed model captures ...
Reactions of copper(II) bromide with 2,6-diacetylpyridine bis(phenyl-hydrazone) (L)-molecular and crystal structure of L and its mixed-valence complex [CuIIL2][CuI2Br4]
(Journal of the Serbian Chemical Society, 2022)
Utilizing X-ray crystallography, the crystal and molecular structures of 2,6-diacetylpyridine bis(phenylhydrazone) (L) were determined. The energetics of the intermolecular interactions in the crystal structure were assessed ...
