LWG Theory of Black Holes for Interpretation and Analysis
Abstract: Black holes are devils of galaxy which can harvest the fabric of space and time to the void of infinity. Light may not come out of the black holes due to the facts sparsely known to the human intelligence. We often strain ourselves to look into the unknown and land in a conclusion which marks our statute towards the human capability. This study proposes theories which may likely control what …

Compact Dual Band Rat Race Coupler Using T-shaped Transmission Line and Fractal Geometry
Abstract: In this paper, a compact dual band rat race coupler is proposed at two different frequency bands. The dual band property is accomplished by transforming the length and impedance of conventional quarter wave transmission line into dual band T-shaped sections. To achieve the compactness, the dual band rat race coupler was transformed into fractal structure using Sierpinski curve analogy. Simple design equations are used for basic design geometries. Then the …

A Novel Mathematical Exploration of Fractal Dynamics in Hyperbolic Spaces
Abstract: This research paper presents an original study on the behavior, generation, and properties of fractal structures within hyperbolic geometry. Unlike classical Euclidean fractals, hyperbolic fractals demonstrate accelerated boundary complexity and distinct scaling symmetries due to the curvature of the underlying space. The paper proposes new iterative models, analyzes geometric invariants, and explores potential applications in data visualization, network science, and theoretical physics. This research paper conducts an in-depth investigation into …

New Design Formulae for Safety and Precision in the Fatigue Engineering of Mechanical Components and Structures
Abstract: This paper introduces two new formulae, termed the Nori Fatigue Formulae, for determining the maximum allowable fatigue stress in mechanical components and structures with significant stress concentrations. These formulae will eliminate the usage of code-sensitive safety factors along with other factored values from the entire mechanical design engineering work, ranging from a safety pin to spacecraft. The first formula gives the maximum allowable fatigue stress in tension, and the second …

AI-Assisted Optimization of Supersonic Airfoil Shapes Using CFD Coupling
Abstract: This paper presents a novel framework for optimizing supersonic airfoil geometries through integrated artificial intelligence and computational fluid dynamics coupling. Traditional gradient-based optimization methods for high-speed aerodynamic shapes suffer from computational expense and convergence difficulties in non-convex design spaces. The proposed methodology employs a deep neural network surrogate model trained on high-fidelity Reynolds-Averaged Navier-Stokes solutions to approximate aerodynamic performance metrics across the design space. A hybrid particle swarm-genetic algorithm searches …

Historical Review of Ionosphere in Perspective of Sources of Ionization and Radio Waves Propagation
Abstract: Before the discovery of ionosphere, the electronic communication was not possible at a distance greater than 100 km due to the curvature of Earth; but after its discovery, the ionospheric wave propagation made possible the electronic communication at even more than 3000 km via reflection of radio waves through ionosphere. The ionosphere is electrically neutral, ranging from 50 to 1000 km in altitude and outer limit can exceed to 3000 …
