Dynamic opto-electro-thermal characterization of solid state lighting devices: measuring the power conversion efficiency at high current densities
(IOP Publishing, 2022-09-22)
Solid state lighting devices with high power densities require accurate characterization, as the rise of chip temperature impacts its optical, electrical, and lifetime characteristics. A detailed experimental study is ...
On the friction stir processing of additive-manufactured 316L stainless steel
(Wiley, 2022-10)
The novel combination of friction stir processing (FSP) and additive manufacturing (AM) is studied herein. Laser-based powder bed fusion of metals (PBF-LB/M) is used to establish 316 L stainless steel with a bimodal ...
A new deep learning restricted boltzmann machine for energy consumption forecasting
(MDPI, 2022-08)
A key issue in the desired operation and development of power networks is the knowledge of load growth and electricity demand in the coming years. Mid-term load forecasting (MTLF) has an important rule in planning and ...
Benchmark study of 2D and 3D VOF simulations of a simplex nozzle using a hybrid RANS-LES approach
(Elsevier, 2022-07-01)
In this study, a simplex nozzle is tested with water for the benchmarking of different flow simulation models. A large scale Plexi-glass transparent nozzle is used to reduce the influence of production tolerances on the ...
Determining the structural life of an electric vehicle battery from road loads
(Walter de Gruyter, 2022-07)
Although the electrical system is important in the development of electric vehicles, the durability of the battery system against mechanical loads and the performance of the battery against shock reactions are just as ...
Lower uncertainty bounds of diffraction-based nanoparticle sizes
(Wiley, 2022-06)
A self-consistent analysis is reported of traditional diffraction-based particle size determination techniques applied to synthetic diffraction profiles generated with the Patterson approach. The results show that dimensions ...
On the development of a novel multi-phase high entropy alloy with transformation-induced plasticity effect
(Elsevier, 2022-06-05)
In the present work, microstructural evolution, and mechanical behavior of a novel high entropy alloy (HEA) are investigated through thermo-mechanical processing. The homogenized samples possess a single-phase cubic structure ...
Identification of unbalance characteristics of rotating machinery using a novel optimization-based methodology
(Springer, 2022-02-26)
In this study, a novel optimization-based method is proposed to determine the parameters of a rotating unbalance in a rotor-bearing system. For that purpose, the weighted sum of squared difference between the analytical ...
Numerical analysis of the radiant heating effectiveness of a continuous glass annealing furnace
(Elsevier, 2022-03-05)
Radiative heat transfer is the dominant mode of heat transfer in glass annealing furnaces. Especially in electrically heated furnaces due to the nonparticipating nature of the furnace atmosphere the radiative heat transfer ...
A type-2 fuzzy controller for floating tension-leg platforms in wind turbines
(MDPI, 2022-03)
This paper proposes a type-2 fuzzy controller for floating tension-leg platforms in wind turbines. Its main objective is to stabilize and control offshore floating wind turbines exposed to oscillating motions. The proposed ...
