Smart IoT Based Battery Management System for EV Battery
Advanced battery management is now essential for lifetime and safety due to the quick spread of lithium-ion batteries in electric cars and renewable energy systems. Static hardware thresholds are usually used by traditional battery management systems (BMS) to guard against overvoltage, undervoltage, and overcurrent. Although these static methods work well for simple defects, they frequently fail to anticipate compounding stress elements that cause thermal runaway or cell deterioration. The design and implementation of a sophisticated, Internet of Things-enabled BMS for a 3S (11.1V) Lithium-ion battery pack is shown in this study. It integrates real-time telemetry with an edge-computed Machine Learning (ML) algorithm. The system accomplishes high-fidelity sensing by using a 16-bit ADS1115 Analogue-to-Digital Converter and an ESP8266 microprocessor dynamic "Risk Score" is continually computed by a Logistic Regression model using voltage, current, temperature, State of Charge (SoC), and State of Health (SoH). The system has a multi-tiered protection procedure that includes a physical relay cutoff during critical stages and a nonblocking audio warning during medium-risk conditions. Additionally, the BMS transmits telemetry to the ThingSpeak cloud platform in its capacity as a smart-grid edge device. The dependability and remote observability of energy storage systems are greatly improved by this predictive method, as demonstrated by experimental data.

Hack Hub
Hackathons have become an essential part of technical education, encouraging students to apply their knowledge, enhance problem-solving skills, and work collaboratively in teams. However, many students face challenges while participating in hackathons, such as difficulty in finding suitable team members, lack of awareness about peers’ skills, limited interaction across different classes or departments, and hesitation among introverted students to communicate openly. These challenges often lead to poor team formation or discourage students from participating in hackathons altogether. To overcome these issues, this project proposes a Hackathon Collaboration Website designed specifically for college students. The platform functions as a professional networking system similar to LinkedIn but focuses exclusively on hackathon-related collaboration. The website allows users to register, create detailed profiles, list their technical and nontechnical skills, share posts related to hackathon ideas, like and comment on posts, and communicate with other students through a chat feature. This helps students identify peers with similar interests and complementary skills, enabling effective team formation. The system is developed using HTML and CSS for the frontend interface, PHP for server-side processing, and MySQL (phpMyAdmin) for database management. The platform ensures secure data handling, easy accessibility, and a userfriendly interface. By providing a structured and centralized environment for interaction, the proposed system enhances collaboration, increases student participation in hackathons, and promotes inclusive teamwork within the college.

Development of Green Concrete using Agricultural Waste Ashes (Rice Husk Ash and Sugarcane Bagasse Ash) as Partial Cement Replacement
The construction industry is rapidly expanding, resulting in increased cement consumption and substantial environmental problems due to greenhouse gases. To mitigate this problem, it is critical to use sustainable and alternative building materials. Agricultural waste materials such as Rice Husk Ash (RHA) and Sugarcane Bagasse Ash (SCBA) are viable sources of supplementary cementitious materials because they are abundant, environmentally friendly, and exhibit pozzolanic properties. This study characterizes RHA and SCBA for use in concrete mixtures. The study conducts analyses of the chemical and physical properties of RHA and SCBA in order to determine their reactivity, compatibility with cement, and overall behavior in concrete mixtures. The study conducts an analysis of the chemical characterization (i.e., silica content, pH, carbonate content and iron content) and physical characterizations (i.e., specific gravity and fineness) of RHA and SCBA to determine the effect on concrete mixtures. In addition, the study conducted workability tests (slump test) of green concrete with 10% total cement replacement for 5% of each RHA and SCBA. The study findings indicate that both RHA and SCBA exhibit high levels of silica and are highly alkaline, suggesting both materials have excellent pozzolanic properties. The physical properties indicate that both RHA and SCBA have much lower densities and finer particle sizes that improve microstructure and particle packing. The workability of the concrete containing both RHA and SCBA showed a slump of 75 mm, indicating a medium level of workability, which is acceptable for practical use. Overall, the study findings indicate that RHA and SCBA are viable and sustainable substitutes for conventional cement materials and that the use of these two materials can help reduce the negative impacts of cement on the environment and improve resource conservation.

How Effective is Origami as a Pedagogical Tool for Teaching Geometric Concepts Compared to Traditional Methods
This review paper examines the effectiveness of origami as a pedagogical tool for teaching geometric concepts in comparison to traditional instructional methods. Geometry is often perceived as abstract and difficult for students to grasp through conventional approaches that rely heavily on definitions and rote learning. In response, educators have explored origami as a hands-on and visual strategy to enhance understanding. This paper analyses multiple teaching approaches that incorporate origami, including algorithmic instruction, language-based methods, collaborative learning, and problem-solving frameworks. The findings suggest that origami can significantly improve conceptual understanding, spatial reasoning, and student engagement when implemented with clear pedagogical intent. In particular, approaches that integrate discussion, reasoning, and mathematical language are found to be the most effective. However, the review also identifies limitations, including the lack of long-term empirical evidence and the dependence on teacher expertise. Overall, origami emerges as a flexible and powerful instructional tool that, when thoughtfully applied, can make geometry more accessible, interactive, and meaningful for learners.

Design and Development of a Portable Generator Using Scrap Materials
The rapid growth of small and medium-scale industries has increased the demand for compact, efficient, and cost-effective internal material-handling solutions. Traditional manually operated trolleys cause significant operator fatigue, reduced productivity, and safety risks when transporting loads above 150 kg. This paper presents the design, development, and experimental validation of an electric material handling cart powered by a 500 W BLDC motor, a dual-mode BLDC controller, and a 48 V, 10 Ah Genesys battery system. The cart is constructed on a robust stainless-steel chassis with optimized dimensions of 1200 mm × 1000 mm × 500 mm, supported by a CNC-machined drive axle, differential mechanism, and 17-inch pneumatic wheels. A chain–sprocket reduction drive provides high starting torque for industrial loads between 200–250 kg and ramp climbing up to 5%. Extensive field testing—including load trials, gradient climbing, structural assessment, runtime evaluation, braking tests, and narrow-corridor maneuverability checks—validated the system's performance. The cart demonstrated a mixed-duty runtime of approximately 50 minutes and a controlled braking distance of 0.35 m, confirming theoretical predictions. Results confirm that the developed electric cart offers a reliable, zero-emission, and ergonomically superior alternative to manual material handling, making it highly suitable for warehouses, workshops, and confined industrial environments.

Effects of Minefields on Livelihood Access of Resettled Internally Displaced Persons IDPs in Borno State, Nigeria
Minefields remain significant threats to civilian populations in post-conflict regions, particularly in areas affected by insurgency. This study examines the impact of minefields on the socio-economic activities of resettled Internally Displaced Persons (IDPs) in selected Local Government Areas of Borno State, Nigeria. The study adopted a mixed-methods approach involving household surveys, Key Informant Interviews (KIIs, and Focus Group Discussions (FGDs). A total of 384 questionnaires were administered to resettled IDPs, while geospatial analysis was used to map landmine and ERW hotspot areas. Descriptive statistics, spatial analysis, and inferential statistics were used for data analysis. The findings reveal that landmine and ERW incidents are concentrated in areas such as Gwoza, Bama, Jere and Kaga Local Government Areas. The presence of explosive hazards has significantly restricted agricultural activities, movement, and livelihood opportunities among resettled IDPs. Risk perception analysis shows that most respondents perceive landmines and ERW as a major threat to their safety and economic recovery. The study concludes that landmine contamination continues to hinder sustainable resettlement and economic recovery in post-conflict communities. The study recommends intensified mine clearance operations, improved mine risk education, and livelihood support programmes for affected populations.
