Thermal-Drift-Aware Adaptive Wavelength Stabilization Model for Silicon-Photonic Optical Communication Systems
Abstract: The increasing integration density and operating speed of silicon-photonic communication devices have intensified the influence of thermo-optic effects on wavelength stability, resonance alignment, optical transmission, and communication reliability. Temperature variations modify the effective refractive index and physical dimensions of photonic structures, resulting in resonance displacement and degradation of wavelength-dependent optical performance. This paper proposes a Thermo- Optical Resonance Tracking (TORT) model for adaptive wavelength stabilization in integrated optical communication systems. …

Influence of Process Parameters on Temperature Distribution and Microstructure of Friction Stir Welded Magnesium Alloy
Abstract: Abstract The effect of processing parameters on temperature distribution and microstructure was evaluated after friction stir welding of AZ31 magnesium alloy plates. Temperature distributions were recorded using thermocouples inserted into the drilled holes. Microstructures of the specimens were evaluated using optical microscopy and grain size and other factors were measured. Microhardness results were evaluated using Vicker’s micro hardness tester. Microstructure results revealed that grain size was reduced and grain structure …

Effect of TMT Bar Lugging on Steel Reinforcement Failure Mode under Monotonic Loading
Abstract: Thermo-mechanically treated (TMT) ribbed bars modify the overall progress of failure in reinforced concrete. The ribs maintain anchorage after friction on the rest of the bar is eliminated during deformation, taking up the ultimate compressive load. This however, is inadvertently jeopardized by the stress concentration effect of the rib geometry. This paper analyses the extent to which some of the geometric forms of bar lugging affect the prevalence of ductile …

Hybrid Polymer Nanocomposites with Enhanced Dielectric and Optical Properties for Wireless Communication Systems
Abstract: The incorporation of nanofillers into polymer matrices offers a promising approach to enhancing the multifunctional properties of composite materials. This study examines the effect of nanofiller concentration on the dielectric performance, mechanical strength, thermal stability, optical absorbance, and electromagnetic interference (EMI) shielding effectiveness of polyvinylidene fluoride (PVDF)-based nanocomposites. Titanium dioxide (TiO₂) and zinc oxide (ZnO) nanofillers were incorporated at varying concentrations to assess their influence on material properties. EMI shielding …

Classical Physics versus Quantum Physics: An Overview
Abstract: Newtonian mechanics is the foundation of Classical Physics. Newton’s mechanics, Thermodynamics, Wave theory of Optics and Maxwell’s electromagnetic theory belong to regime of Classical Physics and can be used to explain a wide range of phenomena in the Universe at macroscopic scale. These theories fail spectacularly when applied to phenomena in the atomic and nuclear regime, for example, proton-atom scattering or the flow of electrons in a semiconductor. Quantum mechanics …

Polymeric Microfluidic Chips for Rapid Point-of-Care Diagnostic Testing
Abstract: Polymeric microfluidic chips have emerged as promising platforms for rapid point-of-care (POC) diagnostic testing by integrating sample preparation, fluid manipulation, biochemical reactions, and signal detection within compact and potentially low-cost devices. Their compatibility with materials such as polydimethylsiloxane (PDMS), polymethyl methacrylate (PMMA), cyclic olefin copolymer (COC), polystyrene (PS), polycarbonate (PC), and polymer–paper composites provide considerable flexibility in device design and manufacturing. Advances in soft lithography, injection moulding, hot embossing, laser …
