Parking management with mobile NFC authentication
This project introduces a mobile application aimed at transforming residential parking management through the use of Near Field Communication (NFC) technology for secure and efficient vehicle authentication. Designed to meet the needs of residents, management, and visitors, the application offers a comprehensive solution to common parking challenges such as unauthorized access, poor space utilization, and lack of real-time monitoring. The key innovation of this system is its integration of NFC-based authentication. Vehicles are equipped with NFC tags containing specific data, which management can scan to verify parking authorization. If a tag fails to return valid data, it may indicate a counterfeit, allowing management to take immediate action and prevent unauthorized parking. This improves both security and transparency in the parking process. To support daily use, the application also enables residents to report illegal parking through a built-in reporting module and request temporary spots if their designated space is taken. For visitors, the system streamlines parking access: residents can reserve a spot and generate a unique reference code. Visitors enter this code into the application to receive their assigned parking lot, ensuring that only approved guests gain access. The management team benefits from a real-time overview of parking occupancy, allowing them to monitor space usage and respond promptly to reported issues. A visual floor plan aids visitors in navigating to their assigned spots, further enhancing usability. Unlike existing solutions, which often address only a portion of the parking management process, this application provides a fully integrated system that combines secure vehicle verification, resident engagement, visitor access control, and real-time administrative tools. The objective is to develop a reliable, intuitive mobile application that leverages NFC for secure sticker validation, facilitates efficient space allocation, and improves communication among users. By enhancing both the security and convenience of parking management, this solution aims to reduce unauthorized parking incidents, optimize space usage, and provide a better experience for all stakeholders

To what extent do digital learning platforms impact the learning experience and academic performance of UTAR FICT students
This research examines the extent to which online learning websites impact the learning
process and academic performance of university students based on the Self-Determination
Theory (SDT). As development in online learning continues to grow, understanding
psychological and academic effects of such online websites has become more important.
Three separate SDT constructs—autonomy, competence, and relatedness—were employed,
and learning experience as the mediator variable, with academic performance as the
dependent variable. Quantitative research design was employed, with a standardized
questionnaire completed by 210 undergraduate students at the Faculty of Information and
Communication Technology (FICT), Universiti Tunku Abdul Rahman (UTAR).
Data collection and analysis were conducted using SPSS software, using descriptive and
inferential methods. Descriptive statistics like mean, standard deviation, skewness, and
kurtosis were used to evaluate data distribution and central tendencies. Internal consistency
greater than 0.70 in Cronbach's Alpha confirmed the reliability of measurement constructs.
Pearson correlation analysis indicated significant correlations between variables. Multiple
regression analysis was used to derive the predictive power of autonomy, competence, and
relatedness to academic performance. Additionally, moderated regression analysis was used
to quantify the impact of learning experience on these relationships as well as including
interaction terms for testing its moderation effect.
The study revealed that autonomy, competence, and relatedness are positively associated with
the learning experience of the students that, consequently, affect the academic performance
positively. The study concludes that, when online learning environments are being designed
to serve the psychological needs of the learners, they may improve academic achievement and
engagement in students. These conclusions are valuable for teaching faculty and institutions
to reaffirm student support systems and online learning approaches at the university level
Parallel metaheuristic algorithm for route planning using CUDA
This research will be focusing on developing a Parallel Metaheuristic Algorithm for Route Planning using CUDA to improve the efficiency and performance of route planning. The increasing demand for more efficient route planning approaches, which includes several factors such as cost savings, timely deliveries and reduced carbon emissions, has led to a surge in demand for more advanced route planning algorithms in search of more efficient solutions.
The problem that this research will be tackling is the Travelling Salesman Problem (TSP), which is a specific type of route planning problem where the main objective of it is to find out the optimal set of routes for a given number of vehicles to transport goods to a defined set of destinations. TSPs are known to be NP-hard problems[1] where an increase in the number of vehicles and destinations will significantly increase the computational time required to obtain an optimal solution. Existing works that utilized metaheuristic algorithms have shown their flexibility in solving multiple TSP variants and their capabilities in obtaining near-optimal solutions within a reasonable amount of time. However, due to the limitations of CPUs in terms of parallelization, these algorithms do not perform well as they are highly iterative.
The proposed approach will be utilizing the Compute Unified Device Architecture (CUDA) to enhance the performance and efficiency of metaheuristic algorithms in finding optimal solutions for the TSP by leveraging the parallel processing capabilities of Nvidia Graphics Processing Units (GPUs). This research aims to significantly speed up solution searching for the TSP by using GPUs compared to CPUs. Besides, this research strives to provide a foundation for future research on parallel metaheuristic algorithms, and to further encourage their implementations in real-world instances of route planning.

Green synthesis of nanomaterials using plant extracts offers a sustainable and eco-friendly alternative to conventional methods. In this study, copper oxide (CuO), zinc oxide (ZnO), and zinc oxide-copper oxide (ZnO-CuO) nanomaterials were successfully synthesized using mangosteen (Garcinia mangostana) leaf extract (MLE). The synthesis process was optimized based on key parameters such as MLE concentration, calcination temperature, and the Zn-to-Cu ratio. The synthesized nanomaterials were characterized using a range of analytical tools to assess their physicochemical properties. The optimized CuO, ZnO and ZnO-CuO nanomaterials were chosen in inhibiting selected bacteria using Broth macrodilution assay and treating palm oil mill effluent (POME) at different conditions under light-emitting diode (LED). In preliminary in vitro antibacterial study, MLE-mediated synthesized CuO nanoparticles (NPs) and ZnO NPs calcinated at 500oC and 0.05 g/mL MLE-mediated synthesized 70ZnO-30CuO nanocomposites (NCs) calcinated at 500oC were chosen due to their small crystalline size. The average particle sizes of the synthesized nanomaterials were 14.31 nm ± 5.368, 29.61 nm ± 12.573 and 23.09 nm ± 10.656 and mostly spherical structure. The ZnO NPs demonstrated the highest antibacterial efficacy with minimum inhibitory concentrations (MIC) of 15.63 μg/mL (Staphylococcus aureus, Bacillus subtilis), 62.50 μg/mL (Escherichia coli), and 125.00 μg/mL (Klebsiella pneumoniae). ZnO-CuO NCs ranked second, with MICs of 62.50 μg/mL, 62.50 μg/mL, 250.00 μg/mL, and 125.00 μg/mL, respectively. CuO NPs were the least effective, showing higher MICs of 250.00 μg/mL, 125.00 μg/mL, 125.00 μg/mL, and 500.00 μg/mL. For POME treatment, ZnO NPs calcinated at 400°C achieved the best performance with COD and AN removal efficiencies at 54.05% ± 0.03 and 38.72% ± 0.00, respectively, using 50 mg of NPs under 120 min of blue LED exposure. In contrast, 150 mg of CuO NPs and ZnO-CuO NCs were required for optimal photodegradation under blue LED for 150 min, achieving COD and AN removal efficiencies of 58.58% ± 0.02 and 38.86% ± 0.01 (CuO NPs) and 59.72% ± 0.02 and 27.80% ± 0.01 (ZnO-CuO NCs), respectively. In conclusion, this study demonstrates the potential of MLE-mediated green synthesis of nanomaterials as a sustainable approach for producing effective photocatalyst and antibacterial agents. ZnO NPs, in particular, exhibit high promise for environmental and biomedical applications. This study introduced a sustainable and environmentally friendly approach to MLE-based nanomaterial synthesis. Additionally, it offered a viable alternative method of bacterial inhibition and a treatment for POME. Moreover, the use of treated POME shown good agricultural development. This study proposed breakthroughs in scientific knowledge of nanomaterial synthesis, antibacterial and photocatalysis mechanisms. This work has a significant contribution to science and society as the results have far-reaching implications for sustainable development, public health and environmental protection – all of which are parallel to the sixth and twelfth sustainable development goals
