Abstract: In the era of data-driven decision-making, organizations face increasing challenges in converting complex datasets into actionable insights. Qlik Sense, a leading self-service business intelligence platform, enables the creation of interactive dashboards and compelling data stories that empower analysts and decision-makers alike. This review explores the principles, techniques, and best practices for effective data storytelling using Qlik Sense, emphasizing the integration of advanced analytics, predictive modeling, and real-time interactivity. The paper begins with an overview of the evolution of data storytelling in BI and the unique capabilities of Qlik Sense’s associative in-memory model, which allows dynamic exploration and discovery of hidden patterns across multiple data sources. It then discusses foundational storytelling principles, the identification of key metrics, and methods for achieving visual and narrative cohesion. Advanced techniques such as set analysis, variables, triggers, and AI integration are examined to illustrate how adaptive and predictive narratives enhance decision-making. Industry-specific applications in finance, healthcare, and retail are analyzed through case studies, highlighting the platform’s versatility in diverse operational contexts. Challenges related to data quality, user adoption, and maintaining narrative clarity are addressed, alongside mitigation strategies and governance recommendations. Finally, emerging trends such as AI-assisted narrative generation, real-time streaming analytics, cloud integration, and multi-platform deployment are explored to provide forward-looking insights. By combining technical expertise, visualization best practices, and narrative design, this review demonstrates how Qlik Sense transforms raw data into actionable stories that drive informed, strategic business decisions.

Abstract: Advances in AI, robotics and construction technology are making in‑situ extraterrestrial building practicable. Demonstrations such as Mars Dune Alpha (NASA/ICON), Lunar Habitat via Contour Crafting (NASA/ICON), and the Autonomous Self‑Growing Structures research (Jin et al. 2023) show technical feasibility, but economic barriers remain the principal threat to long‑term habitation. This paper proposes a concise techno‑economic framework that treats economic sustainability as a primary design parameter, integrating financial intelligence—data‑driven financial planning and decision support, typically aided by AI—with architectural and robotic development. The framework shows how coordinated design, automated fabrication and targeted financial analysis can reduce lifecycle costs and improve value creation. Drawing on a broad literature synthesis and analysis of over 20 government, commercial and student projects (estimates compiled from public sources and open repositories and used here as indicative rather than fully verified), the study offers practical guidance for architects, students and industry stakeholders to mitigate financial risk, structure resilient financing and move space architecture toward commercial viability.

Abstract: This project is primarily designed to ensure real time oil leakage detection and localization using flow rates and echo principles. Flow station A has a microcontroller as the central control unit with start button and flow meter as inputs while time domain reflectometer (TDR), Sound alarm and Pump as outputs. It also has a modem with which it communicates to other flow stations. Flow station B has the same arrangement as flow station A except that it has only sound alarm as its output. Also, the pipeline that links the two flow stations has copper cables aligned along its length so that any attempt to break the pipeline must first cut any of the copper cables which are the basis to detect exact point of leakage using the TDR. Here, fluid flow between two flow stations is considered and the mass flow rates at both ends are measured and compared to check for possible leakage. For a given length of pipeline (L), Cross sectional area (A) and fluid density (ρ) over a given time (t), there is a threshold maximum for mass flow rate difference between flow station A and flow station B. Once, the difference between the two mass flow rates at the two flow stations A and B becomes higher than the given threshold, leakage has occurred, alarm will be activated at both flow stations to alert the workers and the time domain reflectometer (TDR) will be activated at the flow station A. The TDR will send a pulse over the copper cables aligned along the length of the pipeline since for leakage to occur one of the copper cables aligned along the length of the pipeline must have been tampered with. When a pulse is sent across the copper cables, the pulse will be reflected back at a point where the cable is cut. Hence, the TDR measures the time interval between when the pulse is sent to when it was reflected back from the point of leakage as time (t). Then using Echo Equation V=2X/t, where V= Velocity of the sent pulse (3 x 108m/s), hence X=Vt/2 where X is the exact point of leakage as measured from flow station A. The developed system recorded a very low error rate of 0.22% with very high precision.
