A comparison of the Laplace and the alternative multipole expansion series for the Coulomb potential
(Research Gate, 2023)
Multipole expansion is a powerful technique used in many-body physics to solve dynamical problems involving correlated interactions between constituent particles. The Laplace multipole expansion series of the Coulomb ...
Acoustical properties of compressed earth blocks: Effect of compaction pressure, water hyacinth ash and lime
(Elsevier, 2023)
This study assessed the potential use of a mixture of lime and water hyacinth ash (WHA) as binders in fabrication of cylindrical compressed earth blocks (CEBs) with good acoustic absorption properties for building and ...
A Generalization of Poiseuille’s Law for the Flow of a Self-Similar (Fractal) Fluid through a Tube Having a Fractal Rough Surface
(Multidisciplinary Digital Publishing Institute, 2023-01)
In this paper, a generalization of Poiseuille’s law for a self-similar fluid flow through a tube having a rough surface is proposed. The originality of this work is to consider, simultaneously, the self-similarity structure ...
Robust Arduino controlled spin coater using a novel and simple gravity chuck design
(Elsevier, 2023-06)
Spin coaters offer an invaluable method of thin film fabrication. Various implementations, both proprietary and open-source exist, offering vacuum and gravity samples chucks. These implementations vary in their reliability, ...
Mechanical Properties of Al–Mg–Si Alloys (6xxx Series): A DFT-Based Study
(MDPI, 2023-09-13)
Al–Mg–Si alloys are used in aircraft, train, and car manufacturing industries due to their advantages, which include non-corrosivity, low density, relatively low cost, high thermal and electrical conductivity, formability, ...
Acoustics of Compressed Earth Blocks Bound Using Sugarcane Bagasse Ash and Water Hyacinth Ash
(MDPI, 2023-07-15)
Mechanical compaction is often used to densify building earth blocks by reducing the void between the particles. Compacted stabilised earth involves a binder, which holds the particles of the materials together. The ...
Ultrasonic propagation in fractal porous material having rigid frame
(X ECCOMAS Thematic Conference on Smart Structures and Materials, 2023-07-03)
This paper discusses the impact of the fractal structure of porous materials on wave
behavior. In addition to commonly used parameters such as porosity, tortuosity, viscous and
thermal characteristic lengths, a fractal ...
The correlation between equatorial electrojet and equatorial ionisation anomaly over the East African region during the solar minimum period 2008-2009
(East African Journal of Science, Technology and Innovation, 2023-09-29)
This study analyzed the correlation between the equatorial electrojet (EEJ) and the occurrence of equatorial
ionisation anomaly (EIA) over the East African region. The study was carried out during both
geomagnetically ...
Thermal properties and pressure-dependent elastic constants of cadmium stannate as a substrate for MEMS: An ab initio study
(North-Holland, 2023-02-15)
Silicon carbide (SiC) has become a suitable replacement to silicon as a substrate for manufacture of microelectromechanical systems (MEMS) that operate in harsh environmental conditions, owing to its better mechanical ...
A Comparative Thermodynamic Study of AlF3, ScF3, Al0.5Sc0.5F3, and In0.5Sc0.5F3 for Optical Coatings: A Computational Study
(MDPI, 2023-11-27)
Optical coatings are thin layers of materials applied to optical components in order to modify the transmission, reflection, or polarization properties of light. The common materials used for optical coatings include ...
