Epilepsy is one of the chronic brain disorders that affect the quality of life and well-being of millions of people around the globe. It is characterized by excessive electrical activity of the brain’s cells that usually leads to recurrent seizures. Accurate, efficient, and robust techniques suitable for recent Internet of Medical Things (IoMT) devices to detect, classify, and diagnose epileptic seizures in a challenging multi-classification scenario and noisy environment are of paramount importance. Electroencephalograph (EEG) signals recorded even from the surface of the brain suffer from contaminated artifacts and noise from various sources, such as from EOG and EMG for eye-blinks and muscle artifacts, respectively. This work aims to address the challenges of multi-class classification and automatic seizure detection in intracranial EEG signals by developing a detection system suitable for real-world clinical settings. To achieve this, this work uses an effective feature extraction technique and efficient seizure detection methods based on a recent big data resource, along with advancements in deep machine learning techniques, to propose and develop robust hybrid models that combine conventional machine learning techniques and deep learning architectures to increase the performance of epileptic detection systems to levels that are close to acceptable for real-world applications. Firstly, a robust computationally efficient technique that characterizes different types of seizures with high precision and low latency of its onset was proposed. The system relies on an effective and low in complexity feature extraction approach based on the proposed advanced time-frequency Fourier Basel series Expansion based Flexible Time-Frequency Analytic Wavelet Transform (FBSE-FTFAWT) that extracts notable features associated with EEG seizure signals in a time-effective manner. Secondly, two noise robustness seizure detection techniques were developed to address the research question: can the hidden patterns in artifact-induced epileptic EEG data be identified and characterized? Stacked Auto Encoder based Support Vector Machine (SAE-SVM) and Deep Belief Network based Support Vector Machine (DBN-SVM) as hybrid classifiers are proposed with a novel feature extraction to classify various seizure and non-seizure class combinations. The proposed optimized SVM classifier, FBSE-FTFAWT /SAE-SVM, shows better detection accuracy, sensitivity, specificity, precision, and F1-score of 99.7%, 99.6%, 99.6%, 99.7%, and 99.6%, respectively, over the other two proposed models and the state-of-the-art methods in the literature.

Indigofera stenophylla, a member of the Fabaceae family, has been traditionally used in folk medicine for various ailments, including epilepsy among others. This study aimed to isolate and characterize phytochemical(s) from the methanol aerial parts extract of Indigofera stenophylla (MAEIS) and evaluate its anticonvulsant potential. Methods: The MAEIS affords the isolation of compound AR2 through chromatography. The anticonvulsant effect of MAEIS was determined using pentylenetetrazol (PTZ) and strychnine (SCN) induced seizure models. Results: The spectroscopic analysis of the compound AR2 affords 3β, 22.-stigmasta-5, 22-dien-3-ol (stigmasterol). The MAEIS demonstrated significant anticonvulsant activity at graded doses of 150, 300, and 600 mg/kg, reducing both seizure onset and duration in PTZ and SCN models at p<0.05 and p<0.001. The 600 mg/kg dosage provided the most substantial protection. Conclusion: The column chromatographic and spectroscopic analysis of MAEIS led to the isolation of stigmasterol which is a potential bioactive compound with anticonvulsant activity. This is the first isolation of stigmasterol from the plant.

Development of an AI-enabled smart ambulance system for real-time emergency response and traffic navigation
(KIU Journal of Science, Engineering and Technology, 2026) Sani Saminu; Olaosebikan Samuel Tunmise; Suleiman Abimbola Yahaya; Idris Oladele Muniru; Salaudeen K. Olawale; Muhammad kabir Abdulkadir; Sanusi Abdulrazaq; Hauwa Mohammed Hambali
Delay in ambulance arrival during an emergency remains a major cause of avoidable damage, especially in congested areas and under-resourced regions. This project presents the design and development of an artificial intelligence ambulance detection and alert system using public space CCTV cameras. The system uses a Raspberry Pi as the central processing unit, running a deep learning model built on TensorFlow and trained with MobileNetV2 to identify an ambulance. Upon successful detection, an integrated buzzer is triggered for immediate local alert, while a GSM module sends SMS notifications to the nearby hospital or emergency response unit. The system was mechanically designed using TinkerCAD, with a 3D model that optimally arranges the camera, Raspberry Pi, and peripheral components. Circuit design and simulation were conducted using Cirkit Designer to ensure electrical stability and compatibility. This AI-enabled system demonstrated 96% detection accuracy and high precision, providing a reliable, cost-effective, and scalable alternative to GPS or a manual tracking approach. It offers a vital improvement to emergency medical response workflow, particularly in developing environments where smart healthcare infrastructure is still emerging.

Design and Performance Analysis of a Tissue-Load Stable H-Slotted Patch Antenna for 2.45 GHz Breast Phantom Sensing Applications
(Centrepoint Journal (Science Edition), 2026) Salaudeen K. Olawale; Sani Saminu; Yahya A. Suleiman; Muniru O. Idris; Adisa Y. Adebayo
The detection of solid tumors, especially in the breast, is crucial to improving patient outcomes and minimizing the side effects of cancer treatment. This study presents a highly miniaturized rectangular H-slotted PIFA operating in the 2.45 GHz ISM band; the design incorporates an H-shaped slot on top of the radiating patch to reduce the antenna size and improve current-path meandering. Simulation results from CST Studio Suite indicate that the proposed design resonates at 2.45 GHz with a -10 dB impedance bandwidth of approximately 277 MHz (2.33 – 2.61 GHz), a record Return Loss (S11) of -51.65 dB, and a VSWR of 1.005 in free-space conditions, demonstrating a near-perfect impedance match. The antenna exhibits a realized gain of 3.5 dBi at 70% efficiency. and a directional radiation pattern with a directivity of 4.16 dBi, enabling effective electromagnetic energy penetration into breast tissues. The antenna was also shown to be stable in its resonant frequency while modeled within a three-layered breast phantom model (skin-fat-gland). The presence of a 5 mm malignant tumor produces a noticeable shift in the reflection coefficient from -51.65 dB to -39.20 dB, demonstrating the antenna’s sensitivity to dielectric-property variations between healthy and cancerous tissues. Finally, a maximum 1-g averaged specific absorption rate (SAR) of 0.103 W/kg at 10 mW input was achieved, which is substantially below the FCC safety limit of 1.6 W/kg. The results demonstrate that the proposed H-slotted antenna is a compact and stable sensor with the capability to detect early-stage breast tumors effectively
