Drastic microstructural modification of Bi2Ca2Co2Oyceramics by Na doping and laser texturing
(Sociedad Espanola de Ceramica y Vidrio, 2022)
Bi2Ca2-xNaxCo2Oy materials with x = 0 < x < 0.125, have been prepared either by sintering through the classical ceramic method, or textured using the laser floating zone technique. XRD results have shown that Bi2Ca2Co2Oy ...
Improved drift-free P&O MPPT method to enhance energy harvesting capability for dynamic operating conditions of fuel cells
(Elsevier, 2022)
The current study introduces an improved MPPT algorithm to enhance energy harvesting capacity for momen-tary operating situations of FC. The proposed drift-free MPPT is employed to eliminate the situation caused by an ...
Microwave-Based Electrochemical Sensor Design by SRR Approach for ISM Sensing Applications
(Hindawi Limited, 2022)
This paper presents a transmission line and a split ring resonator (SRR) based sensor structure with a high sensitivity capacity to discriminate various methanol mixtures. The height of the dielectric layer and thickness ...
Updated database, semi-empirical and theoretical calculation of Kβ/Kα intensity ratios for elements ranging from 11Na to 96Cm
(Elsevier, 2022)
A collection of 1118 experimental K beta/K alpha X-ray intensity ratios induced by photon impact was published recently by Daoudi et al. [1]. There were errors in some tabulated values. These errors are corrected here, as ...
Microstructural and Tribological Behavior of Pack-Borided Ni-Based Hastelloy C-276 Superalloy
(Springer, 2022)
Although the toughness and corrosion resistance of Ni-based superalloys are high due to their face-centered-cubic structure, their surface hardness and, thus, wear resistance are not satisfactory. The boriding process is ...
Thermoluminescence of hydroxyapatite from eggshell powders doped with Dy synthesized by the sonication chemical method: Effects of doping concentration and heating rate
(Elsevier, 2022)
Hydroxyapatite (HAP) was selected as the host material and synthesized using a sonication chemical method. The effect of Dy3+ ion doping concentrations (0.25, 0.5, 1, 2, 3, 4, 5, 7, and 10 wt%) on the structure and ...
Ionization-induced optical heterogeneity and ion-like direct emission in 1-nm silicon nanoparticle grains: Prospect for fast optical modulation
(American Institute of Physics Inc., 2022)
Silicon, a highly symmetric and homogeneous material, does not exhibit fast optical modulation. Recent classical electrodynamics simulations, however, demonstrated transient optical heterogeneity in silicon nanostructures, ...
Harmonic response analysis of an impeller of a gas turbine engine which modelled by using high entropy alloy materials
(Gümüşhane Üniversitesi, 2022)
One of the problems in a gas turbine’s impeller design is to predict the frequency-stress response caused by the harmonic force resulted from the unbalanced mass. To avoid from impeller’s flaws that may occur, designers ...
Mikrogrid Donatı ile Güçlendirilmiş Zeminde Dairesel Temel Taşıma Gücünün Deneysel Olarak İncelenmesi
(Afyon Kocatepe Üniversitesi, 2022)
Zayıf zeminlerde inşa edilen yapıların temel tasarımı oldukça önemlidir. Bu tür zeminlerde yüzeysel temeller yetersiz kalıyorsa ya bir zemin iyileştirme yöntemi uygulanmalı ya da uygun görülen bir derin temel sistemi tercih ...
Breast cancer diagnosis using deep belief networks on ROI images
(Pamukkale Üniversitesi, 2022)
Hand-crafted features are efficient methods for image processing, recognition, and computer vision. However, the advancements in data size and image resolution lead to inconvenience in feature extraction. Moreover, they ...
