This paper investigates the application of 5G-Advanced networks as a transformative enabler for modern agriculture, offering significant efficiency and cost advantages over traditional wireless sensor networks. By leveraging cutting-edge technologies such as IoT, Multi-access Edge Computing, and Artificial Intelligence/Machine Learning/Deep Learning, this applied research study introduces an innovative framework that shifts actuation decisions from user equipment to the edge, enhancing scalability and simplifying device design. The proposed framework integrates drone-supported intelligent robotics with IoT-driven edge computing, tailored to the unique demands of rural agricultural areas. Case studies from an award-winning TM-Forum catalyst project validate the framework’s efficacy in architecture modeling, focusing on drone-assisted 5G networks, advanced orchestration, network slicing, and ultralow-latency communication. These case studies emphasize precision and scalability in critical agricultural operations such as weeding, irrigation, harvesting, crop, animal and storage monitoring. The findings underscore the potential of 5G-Advanced networks to revolutionize agriculture by enabling precise, efficient, and sustainable practices. This approach addresses diverse system requirements and offers a robust solution for future-ready agricultural technologies, paving the way for a scalable and resilient agricultural ecosystem.</p> Sandor Szekely Leonardo Obinna Iheme Fionan O’Driscoll David Kypuros Vincent Pang Geoffrey Shmigelsky Copyright (c) 2025 NEVU Journal of Engineering and Architecture https://creativecommons.org/licenses/by-nc-nd/4.0 2025-12-31 2025-12-31 3 1 1 15 https://jea.nevsehir.edu.tr/index.php/jea/article/view/21 <p>Ashesi University is a premier destination for diverse visitors, including researchers, scholars, tourists, and industry professionals. However, challenges such as limited tour guides, weather-dependent accessibility, and expansive campus layouts often hinder seamless exploration. To address these issues, this project introduces a smart electric tour cart powered by solar energy and enhanced with IoT-driven automation. The proposed system combines renewable energy and advanced automation to deliver a sustainable, accessible, and interactive touring experience. Key features include GPS-enabled navigation, real-time location-based multilingual audio guidance, and IoT-triggered automation, making the system inclusive for all users, including individuals with disabilities. The cart incorporates a monocrystalline photovoltaic (PV) solar panel to enable on-the-go recharging, reducing reliance on traditional power sources and increasing operational runtime by 30%. Testing validated the cart's performance, achieving a 0.3-meter error margin in location recognition under optimal conditions and reducing CO₂ emissions by 420 kg annually. These results demonstrate its potential to revolutionize campus and recreational tourism, with scalable applications for amusement parks, industrial complexes, and other large venues.</p> Daniel Amoshie Gabriel Owusu Stephen Armah Peter Kwao Copyright (c) 2025 NEVU Journal of Engineering and Architecture https://creativecommons.org/licenses/by-nc-nd/4.0 2025-12-31 2025-12-31 3 1 16 26 https://jea.nevsehir.edu.tr/index.php/jea/article/view/22 <p>Bu çalışmada, S235JR çeliğinin, sıcak daldırma galvaniz yöntemiyle kaplanıp, korozyona karşı mukavemeti ve kaplamanın korozyon ortamında malzemeye etkisi araştırılmıştır. Galvaniz kaplama işlemi 450 ±5°C yapılmıştır. Kaplanan numunelerin metalografik olarak hazırlanması sonrasında kaplama tabakası kesiti optik mikroyapı ve mikrosertlik analiz yöntemleri kullanılarak karakterize edilmiştir. Optik mikroskop analizine göre kaplama tabakası kalınlığı işlem sıcaklığı ve süreye bağlı olarak artış göstermiştir. Mikrosertlik analizleri sonucunda ise kaplama tabakası yüzey sertliği maksimum 458 HV olarak tespit edilmiştir. Elde edilen sonuçlar neticesinde yapılan kaplama işleminin sıcaklık ve süre parametrelerine bağlı olarak malzeme yüzey özelliklerini iyileştirdiği sertlik değerlerinin arttığı görülmüştür.</p> Ahmet Sarı Cemal Çarboğa Copyright (c) 2025 NEVU Journal of Engineering and Architecture https://creativecommons.org/licenses/by-nc-nd/4.0 2025-12-31 2025-12-31 3 1 27 33 https://jea.nevsehir.edu.tr/index.php/jea/article/view/24 <p>In this study, boriding was investigated on the surface of 5630 steel bims mold by using pack cementation diffusion method. For this purpose, a mixture of Al2O3, B4C and FeW and 10% NaBF4 was used as coating powder, and the AISI 5630 steel surface, which was the substrate material, was coated with the pack cementation diffusion method at 1000 °C for 4 hours and at 950 °C for&nbsp; 4 hours. The successfully obtained coated samples were sectioned and their coating morphologies, thicknesses and microhardness were examined. The phase structures formed on the coating surface were obtained by the X-Ray Diffraction method (XRD) and the Fe2B layer assessed by optical microscope and micro-hardness testing. As a result of the study, the lowest coating thickness was obtained on the sample coated at 950 °C for 4 hours. Although the highest coating thickness was obtained on the sample coated at 1000 °C for 4 hours. As a result of the microhardness analysis, it was observed that the hardness of the coating layer was approximately 5 times higher (2416 HV) than the substrate material.</p> Doruk Anıl ALKAN Bülent KURT Copyright (c) 2025 NEVU Journal of Engineering and Architecture https://creativecommons.org/licenses/by-nc-nd/4.0 2025-12-31 2025-12-31 3 1 34 37 https://jea.nevsehir.edu.tr/index.php/jea/article/view/25 <p>Küresel grafitli dökme demirler (KGDD), yapısal özelliği nedeniyle diğer dökme demir türlerine göre daha yüksek süneklik, yüksek mukavemet, yüksek tokluk değeri gibi özellikleri öne çıkmaktadır. Son zamanlarda yapılan çalışmalarda malzeme yüzeyi çeşitli kaplamalar yapılarak iyileştirilebilmektedir. Kaplama yöntemi olarak kullanılan Termoreaktif Difüzyon (TRD) yöntemi basit donanım, kolay uygulanabilirlik, düşük maliyet özelliklerinin yanı sıra malzeme yüzeyinde aşınma, oksidasyon, korozyon dayanımı istendiği takdirde tercih sebebi olmaktadır. Bu çalışmada geniş kullanım alanına sahip olan dökme demir türlerinden GGG-50 malzemesinin yüzeyi TRD yöntemi kullanılarak 900 ^oC, 950 ^oC, 1000 ^oC sıcaklık değerlerinde sırasıyla 2-4 saat süreyle TiC kaplaması gerçekleştirilmiştir. Kullanılan parametreler ile farklı sıcaklık ve sürelerde kaplama tabakalarının değişimleri araştırılmıştır. Kaplama özellikleri X-Işını Difraktometresi (XRD), optik mikroskop kullanılarak incelenmiştir. Elde edilen sonuçlara bakıldığında her kaplama sıcaklığında süreler arttıkça kaplama kalınlığı orantılı olarak artış göstermiştir. Kaplama yapılan numuneler üzerinde ana malzemeden kaplamaya doğru mikrosertlik incelemesi yapıldığında, geçiş bölgesinden sonra kaplama tabakasının gözlendiği alanlarda sertlik derecesinin belirgin ölçülerde arttığı gözlenmiştir.</p> Selin Uğural Sarıtosun Cemal Çarboğa Copyright (c) 2025 NEVU Journal of Engineering and Architecture https://creativecommons.org/licenses/by-nc-nd/4.0 2025-12-31 2025-12-31 3 1 38 43
