A Journey through Fixed Points and Non-expansive Mappings
Abstract: Fixed points in non-expansive mappings are elements that remain unchanged under the action of the mapping. Non-expansive mappings preserve or contract distances in a metric space. The rigorous proof of the Banach fixed-point theorem is presented at the outset of the paper, highlighting its fundamental significance. According to this theorem, every contraction mapping (a particular kind of non-expansive mapping that strictly reduces distances) has a single fixed point in a …

Architecture and the Human Lifespan
Abstract: For centuries, human beings have strived for only one thing in life: to live a long, happy life. From learning to hunt for food and protection, to developing villages and eventually skyscrapers, the goal has always been to live longer and happier. But what really makes humans live longer? Paper suggests that physical health, alone, is not the only contributing factor towards human lifespan. Living a long life consists of …

AI-Based Software-Defined Satellite in Decision Making: A Study
Abstract: For decades, satellites have been a vital infrastructure, relaying communication signals, observing Earth's climate, and providing critical navigation data. However, the traditional model of satellite operation is often rigid and reactive, relying heavily on pre-programmed instructions and ground-based control. This limits their flexibility and responsiveness in a rapidly changing environment. Enter software-defined satellites (SDS), and now, the game-changer: artificial intelligence (AI). Imagine a satellite that can independently analyze its surroundings, …

The Architecture of Creek Road Market and the Image of Port Harcourt Metropolis, Rivers State, Nigeria
Abstract: Marketplaces are seen as centers of attraction in every city. Therefore, the architecture of marketplaces should be given extensive attention to attract a positive image of the city. If the architecture of a market lacks functionality, it will affect the perception of the city. Often, market designers ignore the key users of the market space and focus on providing profit-oriented spaces. This leads to the spillover of trading activities by …

Noise-Driven Collective Behavior in Mean-Field Coupled Lorenz Oscillator Networks
Abstract: This work investigates the spatiotemporal dynamics of an ensemble of 100 identical Lorenz oscillators coupled through a mean-field scheme in the presence of additive noise. Building on prior studies of spatiotemporal chaos in coupled Lorenz arrays and mean-field coupled chaotic oscillators, the focus is on how the competition between deterministic coupling and stochastic forcing shapes collective behavior, including complete synchronization, desynchronization, clustered states, and noise-modified spatiotemporal chaos. The governing equations …
