A Bibliometric Analysis on Bio-Inspired Responsive Facades
(Gazi Univ, 2025-12-01) Bilmez, Busra; Maden, Feray
The implementation of responsive facades offers a promising strategy for reducing operational energy use while enhancing indoor comfort. These facades dynamically adjust their configurations, mirroring adaptive behaviors observed in living organisms. The bio-inspired responsive facade approach integrates principles from biomimicry and responsive architecture to develop systems that react intelligently to environmental stimuli. This study aims to analyze existing literature to identify key developments and trends in bio-inspired responsive facades. The research is conducted in three main phases. First, the study establishes its conceptual framework. Second, a comprehensive bibliometric analysis is conducted using the Web of Science database, employing science mapping techniques via VOSviewer and the Bibliometrix R package. This analysis uncovers major trends, turning points, influential authors, leading journals, and significant conferences, offering a clear overview of the research landscape. In the third phase, 33 facade designs are selected from 141 identified publications for comparative analysis. Each design is examined based on material, control systems, movement mechanisms, and functional objectives. The review explores their natural inspirations, responsive stimuli, and material strategies to derive insights for future innovation. Results reveal that 45% of designs focus on improving thermal comfort in hot climates, often utilizing active systems or smart materials. Folding and rotating mechanisms are the most common modes of movement. However, only five designs progress beyond the conceptual phase, highlighting the need for practical implementation. By mapping the evaluation of this interdisciplinary field, the study establishes a systematic foundation for advancing bio-inspired responsive facade research.
A Novel GNSS Antenna and Array Design with 3D-Printed Stepped Backed Cavity
(Springer Heidelberg, 2025-10-13) Secmen, Mustafa; Yigit, Olcay
In recent years, the use of 3D printing technology for manufacturing RF components and antennas has grown significantly due to its advantages of cost-effectiveness, lightweight, and ease of fabrication. This paper presents a high-gain spiral antenna designed with FR4 and PLA materials, optimized for GNSS band applications. The antenna employs Archimedean spirals and a reflector with a 66 mm air gap, approximately lambda/4 at the lower frequency of the GNSS band, to ensure good circular polarization and axial ratio. The design features a novel conic shape to balance electrical length differences across the frequency band, improving performance. Our results show that the antenna achieves a gain 3 dB higher than similar designs in the literature. Additionally, the use of PLA material reduces coupling effects, allowing the antenna elements to be placed 35 mm closer together in an array configuration. The designed antenna gain is minimum 5.9 dBic and maximum 6.2 dBic, and the axial ratio is minimum 1.8 dB and maximum 2.2 dB in the frequency range. These findings underscore the potential of 3D printing in developing high-performance, compact antennas for advanced communication systems. Furthermore, an antenna array was constructed using the individual antenna elements. The array exhibited the targeted performance, achieving a half-power beamwidth of 36 degrees and a realized gain of 11 dBic.
A UHF RFID-Based System for Real-Time Production Monitoring and Tag Quality Control in the Textile Industry
(SAGE Publications Inc, 2026-01-08) Altuglu, Ogeday; Gunduzalp, Mustafa
In the textile industry, labeling errors during the production process present significant challenges for both quality control and product traceability. This study proposes a real-time RFID-based production tracking and label quality control system to address these issues. In the developed system, RFID tags attached to products are read by embedded devices equipped with RFID readers integrated into the production lines. The captured product code data is transmitted to a local server via MQTT. The server verifies the tags by querying a central database and provides instant feedback to the corresponding device. The system runs entirely over a local network and does not require an external internet connection, ensuring uninterrupted functionality even in infrastructure-limited environments. This architecture enables all devices on the production line to communicate synchronously with the server, maintaining system-wide consistency and integrity. In this way, the use of a single tag per product is ensured, and faulty tags are filtered out. Furthermore, the system evaluates tag readability to detect quality issues such as stitching errors, physical deformation and alerts the operator through feedback. As a result, defective products are identified and removed before production is completed, helping to reduce time loss, and improve overall production reliability.

Africa’s Green Hydrogen Trajectory: A Multidimensional Review of Technology, Economics, Infrastructure, and Social Justice
(Pergamon-Elsevier Science Ltd, 2026-04) Hepbasli, Arif; Tiktas, Asli
Although Africa possesses some of the world's most abundant renewable resources, it faces formidable infrastructural, financial and socio-environmental barriers to green-hydrogen deployment. To provide a holistic evidence base for policymakers, this study combines a systematic narrative review of 50 peer-reviewed and grey-literature sources with bibliometric mapping and a multidimensional evaluation matrix. Publications have increased dramatically since 2020. After removing query anchor terms from keyword rankings, the bibliometric mapping highlighted second-order thematic foci-such as desalination/water, ammonia/derivatives, infrastructure/logistics, certification/GoO, and policy/finance themes-that bridge technical and socio-economic research. A continental comparative matrix assessed technological readiness, economic viability (LCOH: levelized cost of hydrogen), infrastructure readiness, regulatory preparedness and socio-environmental justice across seven key countries. In this review study, socio-environmental justice was defined and assessed as a set of operational, evidence-traceable safeguards and distributional risk exposures associated with hydrogen deployment, covering (i) water sourcing and allocation governance (competition with domestic users, desalination/brine externalities, and conflict-mitigation measures), (ii) land-tenure and displacement protections for renewable plants and corridor rights-of-way, (iii) procedural justice via documented consultation/participation provisions (including FPIC where applicable) and grievance-redress mechanisms, (iv) benefit-sharing and local value-capture instruments (local content, training, community service co-benefits), and (v) environmental safeguards, monitoring, and enforcement capacity; these elements were scored through predefined sub-indicators, with inverse scoring applied for risk-type proxies so that higher environmental justice values consistently represented stronger safeguards and lower socio-environmental risk. The evaluation matrix was operationalized using a transparent, rule-based scoring rubric in which multiple sub-indicators were normalized to a consistent 0-1 scale (via threshold-based and min-max transformations, with inverse scoring for risk-type indicators), aggregated into five pillar scores, and combined into a composite readiness score; robustness was examined through alternative entropy-based weighting and Monte Carlo uncertainty propagation (with percentile intervals reported). Egypt topped the ranking owing to plans for more than 15 GW of electrolyzer capacity and 47 desalination plants (6.4 million m(3)/day, 20% earmarked for hydrogen), achieving source-reported plant-gate PV-only LCOH values in the range of 3.13-4.21 EUR/kg H-2 (source-reported; providing FX-harmonized USD/kg H-2, 2050 scenario), under the financial and technical assumptions (e.g., WACC 7.49-11.26% and 26-year project life). Morocco and South Africa followed closely due to liberalized electricity frameworks and established port infrastructure, whereas Namibia and Mauritania, despite world-class solar and wind resources, scored lower because of remote project locations and high capital costs. Kenya's nascent program anchored on geothermal power resulted in the highest LCOH (>4.2 USD/kg H-2) and low policy scores. Analysis of policy documents revealed only Namibia and Mauritania have enacted dedicated hydrogen legislation; most other countries lack certification schemes and Guarantees of Origin.Physical observations-extreme solar irradiance (>2200 kWh/m(2) yr ), steady coastal winds, acute water scarcity and desert conditions-explain why desalination, transmission networks and port upgrades are decisive for lowering costs. High financing costs (with WACC varying strongly by project structure: a high/risk-adjusted case of 11-15% is used in some studies, concessional or de-risked structures can fall in the 2-6% range, and a central benchmark of similar to 8% is also commonly reported) and reliance on export markets further constrain competitiveness. The study concludes that unlocking Africa's hydrogen potential requires synchronizing infrastructure investment with transparent regulatory frameworks and socio-environmental safeguards, thus transforming abundant natural resources into inclusive industrial development.

AIndividualism and Algorithmic Collectivism: Rethinking Individual-Collective Dynamics in the Age of AI
(Springer, 2026-02-15) Ozerim, Mehmet Gokay
This study explores how artificial intelligence reshapes the long-standing relationship between individualism and collectivism. It argues that AI does not simply shift the balance between these perspectives, but transforms how they coexist and evolve in contemporary societies. Drawing on Deleuze's idea of Societies of Control and Taylor's theory of self-determining individualism, the paper introduces two related concepts: AIndividualism and Algorithmic Collectivism. The first describes new forms of hyper-personalized autonomy produced through algorithmic personalization and continuous data feedback. The second refers to emerging modes of collective identity and coordinated action that develop within digital infrastructures guided by algorithms. By examining these dynamics together, the study shows that technology can both expand individual agency and cultivate collective forms of organization. AI enhances self-determination while also generating algorithmic collectivities that influence belonging, meaning, and social coordination. These intertwined processes reveal a central paradox of digital modernity: technology empowers individuals even as it aligns them through shared algorithmic systems. The discussion moves beyond binary thinking about autonomy and community, suggesting that both now unfold within the same technological frameworks. Understanding this dual process is crucial for developing ethical and policy responses that reflect AI's impact on human agency and social life. The paper concludes that the challenge of the AI age is not to choose between the individual and the collective, but to sustain both in a balanced and responsible way within an increasingly algorithmic world.

Analysis of M/M/s Make-to-Stock Queues with Production Start-up Costs for Both Lost Sales and Backordering Cases
(Taylor & Francis Ltd, 2025-11-20) Ozkan, Sinem; Bulut, Onder; Dincer, Mehmet Cemali
This study considers a production-inventory system with production start-up costs and parallel production lines. Production times are independent and identically distributed exponential random variables and demands are generated according to a stationary Poisson process. Production and inventory are controlled by the extended-two-critical-number policy. The system is modelled as an M/M/s make-to-stock queue and analysed for both lost sales and backordering cases. A renewal approach is developed to calculate the expected average system cost. Furthermore, an approximation is proposed to calculate the control parameters of the extended-two-critical-number policy. An extensive numerical study is conducted to illustrate the effects of changes in system parameters and the effectiveness of the proposed approximation. The analysis shows that the proposed approximation performs well across various system conditions.
