Design And Fabrication of Contactless Magnetic Gears
Abstract: Modern engineering prioritizes speed, efficiency, and reliability, spurring innovations like contactless magnetic gear systems that transmit torque through interacting magnetic fields from permanent magnets, eliminating physical contact to drastically cut friction, backlash, wear, lubrication needs, and heat—operating silently with minimal vibration and peak efficiencies up to 99% under ideal conditions, outperforming traditional gears in low-speed, high-torque direct-drive applications such as motors. The design centers on two rotors: an outer high-speed …

Zeolite-Y Encapsulated Copper (II) and Cobalt (II) Species as Hybrid Nano-catalysts: Structural and Catalytic Aspects
Abstract: Special properties inherent to zeolites in facilitating the construction of novel upramolecular assemblies by encapsulation of guest molecules (metal complexes) into their large cages can be utilized to use these assembled materials as novel catalysts. These modified solids have the advantages of both behaving as the homogeneous and the heterogeneous catalytic system. In the present work, copper (II) and cobalt (II) complexes of 2-amino ethanoic acid (2-AEA) encapsulated in the …

Effect of Particle Size of Sand on the Interface Shear Behavior of Sand and Non-woven Geotextile
Abstract: Soil-geosynthetic interface is the weakest zone for shear failure. It is influenced by size, shape, density and water content of sand. It is also influenced by the properties of geosynthetic such as texture and structure. This paper explores the influence of the size of sand on the behavior of sand-geotextile interface. Three types of sands namely coarse, medium and fine sand and non-woven geotextile were used in this study. Several …

Role of ion Regulation in Heartbeat Initiation
Abstract: The heart can beat quite 2 billion times in normal life, but the mechanism by which the guts beats is that the subject of intense research. Since the invention of pacemaker currents in 1978, several studies have shown that rhythmic changes in membrane tension (the "membrane tension clock") underlie the mechanism of automation. It's the depolarizing current activated during hyperpolarization. Therefore, when the guts cells recover, it's activated, the cell …

The Fundamental Premises of Efficient Linear Regression and Applying Regression
Abstract: Linear regression is a statistical technique for estimating the value of a dependent variable from an independent variable. Linear regression is a way to assess how two variables are related. A dependent variable is predicted using this modelling technique based on one or more independent factors. Many analyses are based on linear regression. Sometimes the data must be changed to satisfy the needs of the analysis, or extra room must …

Twisting, Super Twisting and Adaptive Algorithm Sliding Mode Controller for Second Order Time Delay Systems
Abstract: The sliding mode control approach is widely considered as one of the most effective methods for designing a reliable controller for a complicated higher-order dynamic plant operating under uncertainty. The primary advantages of sliding mode is its low sensitivity to changes in plant parameters and the ability to entirely eliminate disruptions. Sliding mode control has been widely applied as a robust control design methodology that is completely insensitive to uncertainties, …
