Topology-Driven Fault Detection in Smart Cities Topology-Driven Fault Detection in Smart Cities: Utilizing Dynamic Graph Filtrations and Persistent Homology for IoT Connectivity Patterns Shrishti Rastogi / Research Article Abstract: The rapid proliferation of IoT devices in smart cities necessitates robust, real-time monitoring systems to detect infrastructure faults. Traditional graph-theoretic methods often fail to capture multi-scale structural changes under fluctuating environmental conditions. This paper presents a topology-driven framework utilizing Topological Data Analysis (TDA), specifically persistent homology, to analyze time-varying graph filtrations of IoT connectivity patterns. We integrate Distance-to-Measure (DTM) filtrations to mitigate noise, coupled with machine learning classifiers applied to stable topological summaries. Empirical evaluation on simulated smart city datasets demonstrates superior F1-s...

Bharat: Development or Destruction? Bharat: Development or Destruction? A Mathematical Comparative Study of Agriculture, Water, Air, Health, Economy, and Human Development (1950-2025) Abstract India's post-independence history contains a central paradox: the country achieved dramatic improvements in food security, income, education, infrastructure, and life expectancy, while also experiencing groundwater depletion, air pollution, soil stress, ecological loss, inequality, and social fragmentation. This paper develops a mathematically explicit framework for evaluating whether India's transformation from 1950 to 2025 is better described as development, destruction, or an unstable mixture of both. We propose a Mathematical Comparative Index (MCI) that combines agriculture, environment, economy, health, education, and social indicators using signed normalization, robust baseline comparison, entropy-adjusted weights, nonlinear ecol...

Abstract Macroscopic biological entities, such as the retina and the human brain, as well as the whole organism, are required to be continuously coherent at room temperature, which is a huge challenge for modern quantum mechanics. Biological tissue is warm, wet and noisy, and this is theoretically expected to result in rapid decoherence, but growing paradigms in quantum cognition and quantum biology indicate that the neural systems somehow avoid immediate collapse induced by environment. One of the unsolved problems in this area is the exact mechanism of how cellular structures are able to remain decoherence-free and support potentially functional quantum states. The aim of this paper is to answer this salient research gap by proposing a theoretical framework for modelling the phenomenon of quantum entanglement and non locality in the brain cell microtubules and retina photoreceptors. Combining the elements of the resource theory of quantum coherence and open quantum dynamics, we propo...

Abstract   Gabriel's horn is a classic mathematical example of a finite volume with an infinite surface area which is also known as the Painter's Paradox. This paradox states that an infinitely large surface area would need to be coated with an infinite amount of material, in this case a paint, while it is possible to fill the interior with a finite amount of material. This paper brings together the fields of pure mathematical theory and applied computational physics by introducing a computational framework that can be used for the modeling of the hypothetical filling of Gabriel's horn with sophisticated numerical discretisation methods. Using finite volume methods (FVM) and implicit-explicit (IMEX) time integration methods, we build a hypothetical simulation pipeline to deal with the extreme geometrical tapering of the domain. The theoretical study shows that the advanced numerical schemes can effectively address the boundary interface issues in configurations that t...
