Prioritizing Physical Comfort Conditions in Primary School Design: Insights from Teacher Perspectives in Algeria
Full text linkThe design of primary schools has evolved gradually over time, with each period reflecting changes in specific aspects of educational and environmental needs. The current trend emphasizes the integration of computer technology into the school environment, aiming to create a space that supports both traditional and digital methods of teaching. However, in Algeria, these concerns are still not fully addressed. Instead, the focus remains on creating a physical environment that facilitates knowledge transmission and offers a more comfortable space for both students and teachers. In architectural design, achieving an optimal balance of comfort is challenging, often forcing architects to prioritize some aspects over others. Determining which form of comfort should take precedence is therefore crucial. This study aims to identify and prioritize the physical comfort conditions most essential for effective learning environments. To accomplish this, we conducted a thorough theoretical review to identify the key factors influencing physical comfort and potential disruptions to the learning process. Furthermore, we surveyed primary school teachers to rank these conditions based on their perceived importance. The findings provide valuable insights into the challenges teachers encounter in the classroom, offering a foundation for informed decision-making in future school design initiatives

LEVERAGING MACHINE LEARNING FOR RAINFALL PREDICTION IN NORTH-CENTRAL NIGERIA: COMPARATIVE ALGORITHM STUDY
Full text linkRainfall has been a major worry in recent times because of the weather patterns that are constantly changing. The last ten years, in particular, have seen significant changes in rainfall patterns due to global warming. The principal determinants of this rainfall pattern include precipitation, dew points, wind speed, pressure, temperature, and humidity. For the purposes of agricultural growth and precise rainfall forecasting, it is essential to comprehend the relationship between these variables and rainfall behaviour. This is particularly true for the north central region of Nigeria, which is known as the country’s “food basket.” This work aims to investigate how machine learning techniques might infer precipitation patterns in north-central Nigeria. This study looked at several algorithms and evaluated how well they performed in respect to each variable that was connected to the goal variable. We also examine the performance of several machine learning methods in predicting rainfall. The outcome demonstrates the potential of the Random Forest Regression Algorithm as a flexible method for comprehending and controlling rainfall patterns. Thus, it is advised that the Nigerian Meteorological Agency (NIMET) use the outcome in conjunction with the traditional NWP (Numerical Weather Prediction) method to further improve rainfall prediction. The result will help farmers optimise their planting and harvesting schedules, assist water resource managers in planning for different water usages, allow disaster management authorities to issue timely warnings, support the conservation of natural resources, and ultimately promote economic development through infrastructure planning
Enhancing Security and Customization in IoT-Based Systems with Applications to Broiler Room Management
Full text linkAlthough IoT-based solutions are widely employed in various fields, they frequently rely on traditional email notifications or third-party platforms like ThingSpeak, Blynk, AWS IoT, Microsoft Azure IoT, and Google Cloud IoT for monitoring and control. These strategies do, however, have significant disadvantages, such as restricted adaptability and customization, security flaws, and privacy issues with data. In order to overcome these constraints, this work presents an improved software solution that is incorporated into an ESP32 IP address-based interface, with particular applications for managing broiler rooms. By combining IP address-based access with secure login authentication using a username and password, the suggested method makes sure that only authorized users can watch over and manage the broiler room. Significant gains in security, privacy, flexibility, and user-specific customization are shown by the experimental findings. The system is easy to install and use. It offers a reliable substitute for IoT-based systems by doing away with the need for third-party platforms. Because of its flexible nature, users can customize features to meet particular requirements, getting around the strict limitations of third-party frameworks. This system provides secure remote access with increased mobility, in contrast to email-based alternatives that lack real-time involvement. This approach adds login authentication and customization styles to the current program by integrating hardware and parts of the software from our prior system [1]. The suggested approach performs better than the prior system and other IoT-based systems that rely on third-party platforms in terms of security and customization
Geophysical Investigation of Damped Patches on Foundational Wall: A Case Study of Jalala, Tanke-Oke-Odo, Ilorin, Nigeria
Full text linkThe issue of dampness in buildings in Jalala Oke-Odo, Ilorin, Kwara State, Nigeria, poses significant concerns due to its potential to compromise both the health of occupants and the structural integrity of affected buildings. To investigate the underlying causes of this widespread problem, non-destructive geophysical methods—particularly the Electrical Resistivity Method—were employed to assess soil and subsurface conditions. This approach enabled the identification of anomalies in soil composition and the detection of subsurface water sources contributing to dampness. A key objective of the study was to produce detailed subsurface maps around building foundations, providing engineers and contractors with critical data for designing targeted interventions to mitigate damp-related issues and prevent long-term structural damage. The study underscores the serious risks associated with prolonged dampness, including the progressive weakening of foundation walls and the potential for building collapse, posing a grave threat to resident safety. Resistivity measurements revealed variations in the water retention capacity of subsurface lithology. Geoelectric cross-sections showed area with low resistivity at various depths, indicating the existence of impermeable or semi- permeable weathered rock materials, which are major contributors to persistent damp patches. Hence, this geophysical investigation offers important insights into the geological factors influencing dampness in Jalala Oke-Odo. The research serves as bases for effective remediation policies to enhance the resilience of structures and protect life. It also highlights the need for proper understanding of subsurface conditions to tackle dampness issues in developing regions

Full text linkيتناول هذا البحث دور أدوات الذكاء الاصطناعي الشائعة، مثل Grammarly وHemingway، في تحسين مهارات الكتابة لدى متعلمي اللغة الإنجليزية من غير الناطقين بها. تُظهر الدراسة كيف تساهم هذه الأدوات في تحسين الكتابة من خلال تقديم ملاحظات في الوقت الفعلي تركز على المشكلات النحوية والمفردات والتماسك والوضوح اللغوي.
تم إجراء مقابلات مع الطلاب ومدرسي اللغة، إلى جانب تحليل النتائج، مما أبرز التحديات والمزايا المرتبطة باستخدام الذكاء الاصطناعي في تعليم الكتابة. تشير النتائج إلى أن هذه الأدوات يمكن أن تسهم في تصحيح الكتابة، وتعزيز ثقة المتعلم، وتحفيزه على المخاطرة بالتصحيح الذاتي، وتطوير مهاراته في معالجة الأخطاء. ومع ذلك، تطرقت الدراسة إلى بعض الجوانب السلبية، مثل الاعتماد المفرط على هذه الأدوات، والصعوبات التي قد تواجهها في التعامل مع التعقيدات اللغوية الدقيقة، والدقة الثقافية، والتعبيرات السياقية.
بناءً على ذلك، توصي الدراسة باستخدام أدوات الذكاء الاصطناعي كوسيلة داعمة للتعليم التقليدي للكتابة، وليس كبديل عنه. كما تؤكد على أهمية دمج ملاحظات الذكاء الاصطناعي في ممارسات التدريس بشكل نقدي، مع التركيز على دور المعلم في توجيه الاستخدام الفعّال لهذه الأدوات.This document addresses, using examples of popular AI tools including Grammarly and Hemingway, how such similar tools assist their use in improving non-native English learners\u27 writing through real-time feedback on grammatical, syntactical, vocabulary-related, coherence, and clarity issues. Interviews were conducted with students and language instructors and together with analysis of the results underscore several issues-both challenges and advantages being that of implementing AI in writing education.
Research indicates that the tools can correct writing, improve the confidence of a learner, motivate a learner to take risks in self-correction, and foster skills in making corrections when errors appear. Negative aspects include feeding dependency and difficulties that can arise with dealing with intricate aspects of language nuances, cultural subtleties, and context-specific expressions. It is thus recommended that AI tools should support and not substitute what is going on in traditional writing instruction, thus implying the integration of AI feedback into teachers\u27 practices for personalized use, all while assuming a critical stance toward it
