Development of an AI Model for Automated Cervical Cancer Screening Based on Cytology Whole Slide Images
Cervical cancer (CC) is the fourth leading cause of cancer-related deaths among women globally, posing a significant health challenge, especially in developing countries with limited healthcare resources. Traditional screening methods like the Pap smear, despite their success in early detection and reduction of CC incidence, face limitations such as labor-intensive analysis and subjective interpretation. Recent technological advancements in artificial intelligence (AI) and computer vision offer promising improvements in CC screening. This study focuses on developing and evaluating a convolutional neural network (CNN) for automated analysis of cervical cytology images from the SIPaKMeD database, which contains 4049 images categorized into five cell types: dyskeratotic, koilocytotic, metaplastic, parabasal, and superficial-intermediate. The proposed CNN architecture includes convolutional layers, MaxPooling, and Dropout layers to prevent overfitting, optimized using the Adam algorithm. Preprocessing steps such as color normalization, noise reduction, and artifact removal were applied to digitized slide images. The model's performance was assessed using accuracy and recall metrics. Results showed the CNN achieved high accuracy of 92% and sensitivity of 22%, with validation accuracy closely tracking training accuracy, indicating effective learning and generalization. The study demonstrates that Artificial Intelligence (AI) can significantly enhance CC screening accuracy and efficiency, addressing current limitations in traditional methods. Further optimization, including addressing class imbalance and exploring data augmentation techniques, is recommended to enhance the model's predictive capabilities and robustness in diverse clinical settings

Meta-Heuristics Algorithms of Intelligent Parking System on a Rush Hour Centre in Space Transport and Propulsion
Abstract
The search for parking space is a time consuming process which not only affects the economic activities efficiency, but also the social interactions and cost. The need for efficient parking management systems especially during rush hour cannot be emphasized enough for such cities. Therefore, this study seeks to provide a solution to the issues by hybridizing two algorithms: Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) during rush hour in space transport and propulsion at a particular city Epe in Nigeria. This was measured by some metrics parameter such as Time-taken, Cost and User-satisfaction to solve the problem of premature convergence. The three algorithms: (GA-PSO, PSO and GA) using a Matric Laboratory (MATLAB) program in an intelligent parking system tried to allocate the route for the user vehicle in an optimal manner. GA-PSO solved the parking allocation problems by obtaining minima values in terms of the cost and time taken with high user satisfaction. The experimental results demonstrated an accurate and robust car parking space allocation algorithm. In return, a GA-PSO based car parking space allocation algorithm produced a reliable car parking allocation system
