Determination of the bearing capacity of model ring footings: Experimental and numerical investigations
(Techno Press, 2019)
In this paper, it was presented an investigation on the load-settlement and vertical stress analysis of the ring footings on the loose sand bed by conducting both laboratory model tests and numerical analyses. A total of ...
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 ...
Passive Flow Control of Ahmed Body using Control Rod
(Universiti Malaysia Pahang, 2022)
In the current study, numerical analysis of passive control flow with a control rod for Ahmed body is performed at different slant angles and velocities and placed rod locations on the slant surface. The aim of the study ...
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 ...
Data clustering using leaders and followers optimization and differential evolution
(Elsevier, 2022)
Data clustering is an important research topic in data mining. Although cluster analysis based on optimization algorithms has attracted great attention, optimization-based techniques face difficul-ties due to the non-linear ...
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 ...
Operational risk assessment of ballasting and de-ballasting on-board tanker ship under FMECA extended Evidential Reasoning (ER) and Rule-based Bayesian Network (RBN) approach
(Elsevier, 2022)
Ballasting and de-ballasting operations play a critical role in maintaining stability and safety onboard tanker vessels. The process involves considerable risks to human health, the marine environment and property since ...
