Studying Some Optical Properties of Magnesium Oxide by Depending on Different Thicknesses
type: item
description: This study investigates the optical properties of magnesium oxide (MgO) thin films with different thicknesses (16, 24, and 36 nm) using a UV–Vis spectrophotometer (Min 1240). The absorbance spectra showed a similar behavior for all samples, with a sharp increase around 460 nm, and higher absorbance values for thinner films. The transmittance spectra revealed a decrease with decreasing thickness in the wavelength range of 382–487 nm. The absorption coefficient (α) was calculated and found to be greater than 6.64 × 10⁴ cm⁻¹, indicating direct electronic transitions. The optical Energy gap (Eg) was determined using the Tauc method and found to be 2.558 eV. A slight decrease in Eg with increasing thickness was observed, attributed to structural changes, including reduced defect density and grain-boundary effects.

Optimizing Face Recognition Accuracy through Eigenfaces and K-Nearest Neighbour: An Empirical Study
type: item
description: Face recognition has emerged as a cornerstone of computer vision research, spurred by its expansive utility in security systems, surveillance, and human-computer interaction. This study develops a robust face recognition framework that integrates the Eigenfaces methodology for sophisticated feature extraction with the K-Nearest Neighbour (KNN) algorithm for classification. By leveraging Principal Component Analysis (PCA), Eigenfaces are generated to significantly condense the dimensionality of facial datasets while preserving the most salient discriminative features. These optimized feature vectors are subsequently processed via a KNN classifier, utilizing a range of K values to perform a thorough evaluation of the system's operational performance. The empirical findings reveal that the proposed methodology yields high recognition accuracy alongside stable computational overhead, suggesting that the selection of an optimal K value is essential for balancing predictive precision and processing efficiency.

Design and analysis of a metamaterial shielding chip for mobile phones to reduce EM radiation in Human Head
type: item
description: This study focuses on the development and evaluation of a shielding chip made from metamaterials, designed to decrease the absorption of electromagnetic (EM) radiation by the human head from mobile phones. As public concern rises regarding long-term exposure to radiofrequency (RF) emissions, effective personal protection technologies are increasingly important. The proposed shield uses a custom-engineered metamaterial pattern to absorb and deflect EM waves, which lowers the Specific Absorption Rate (SAR) in cranial tissues. Simulations using the Finite Element Method (FEM) were performed across various 5G frequencies. These simulations utilized a detailed, multi-layered anatomical model of the head, including skin, fat, bone, dura, cerebrospinal fluid (CSF), and brain tissues. The analysis assessed critical metrics under realistic conditions, including SAR distribution, electric field attenuation, penetration depth, reflection coefficient (S11), and induced temperature changes. The findings show that the metamaterial chip substantially reduces SAR levels, especially in tissues with high water content. Both the 1-gram and 10-gram averaged SAR results stayed under the 1.6 W/kg regulatory limit set by the Federal Communications Commission (FCC). The shield exhibited strong wave-absorbing properties, with a notable performance at 2.4 GHz characterized by low reflection and no substantial thermal increase in head tissues. The research concludes that the metamaterial-based shielding chip presents a practical and effective approach for mitigating EM radiation exposure from mobile phone usage.

Gender and Age as Determinants of COVID-19 Outcomes
type: item
description: Background: SARS-CoV-2, first detected in late 2019, rapidly developed into a global health crisis. Evidence consistently shows that males experience more severe COVID-19 outcomes than females, and age plays a significant role in determining disease severity. Findings from this study suggest that males have a slightly higher risk of acquiring the infection and developing severe illness, while young individuals under twenty years of age show greater resistance. Conversely, those aged sixty years and above are more likely to experience severe manifestations, although susceptibility decreases among males older than seventy-five. Objective: The purpose of this study was to evaluate how gender and age influence COVID-19 infection patterns, disease severity, mortality, and prognosis. Only 198 confirmed cases were analyzed, consisting of 120 males (60.4%) and 78 females (39.6%), from January 2021 to January 2022. Results: Our results indicated that males were more affected by COVID-19 than females. Younger individuals demonstrated the lowest susceptibility, while elderly patients were the most vulnerable. Infection rates among males beyond the age of seventy-five showed a decline.

Modeling and Dynamic Analysis of Pitch Motion Control of an Aircraft System
type: item
description: Safe and efficient flight operations require accurate and steady aircraft pitch angle control. Conventional control approaches struggle to achieve ideal transient response characteristics like minimum overshoot and fast settling time. This thesis compares aircraft pitch angle control techniques. Due to its instability, the open-loop aircraft pitch system requires powerful feedback control. This paper simulates the longitudinal dynamics of an aircraft pitch control system and builds PID controllers utilizing Trial-and-Error, Ziegler-Nichols, and GA-based optimization. A Model Predictive Control (MPC) technique is also tested. While Trial-and-Error and Ziegler-Nichols conventional PID tuning approaches stabilize the system, simulation studies show that they have higher overshoot and longer settling periods in transient response. The GA-optimized PID controller has a faster reaction (0.204 s, peak time 0.619 s, settling time 1.25 s) and a 5.79% reduction in overshoot. With comparable performance measures (settling time of 1.33 s, overshoot of 6.11%), the MPC technique works well in complex control contexts. A thorough comparison shows that the GA-tuned PID controller beats classical PID approaches and MPC in important transient response characteristics. This shows that artificial intelligence can optimize aircraft pitch control systems better. The results show that GA-based tuning can provide accurate and robust control, providing insights for aerospace control system design.

Forecasting Solar Power Generation Using Real Meteorological Data and Machine Learning Techniques
type: item
description: Accurate short-term forecasting of photovoltaic (PV) power is critical for grid management and energy planning. We analyze a real year-long meteorological dataset (including irradiance, temperature, wind, etc.) and simulate corresponding PV output (derived from irradiance and temperature with efficiency factors). Using this data, we train and evaluate four models Random Forest (RF), XGBoost (XGB), Long Short-Term Memory (LSTM), and a Hybrid Ensemble – for 1-hour, 3-hour, and 6-hour ahead forecasts. Models use features such as global horizontal irradiance (GHI), temperature, wind speed, humidity, and time-derived cyclic variables. Performance is measured by RMSE, MAE, and R². Results show that ensemble tree methods (RF and XGB) outperform LSTM for this task, with RF often giving the lowest error. As horizon increases, forecast accuracy degrades (higher RMSE) due to meteorological variability. Feature importance and correlation analysis indicate that irradiance is the dominant predictor of PV output, with nearly perfect correlation (R²≈0.99) to power. We include detailed experiments, visualizations (e.g. actual vs. predicted curves, error trends), and discuss the implications of hybrid models combining ML and time-series techniques.

Study of the properties of lightweight concrete and its potential use as an alternative to hollow bricks for roof slabs using polystyrene granules
type: item
description: The research summarizes the conduct of tests on lightweight concrete (lightened by the addition of polystyrene beads) in terms of density, compressive strength, weight, and absorption rate. All these tests are conducted on three mixes of lightweight concrete using polystyrene beads, and the best mixes are selected in terms of weight lightness and absorption rate. Consequently, the possible and available uses of this concrete are deducted, such as sloping layer works and the manufacturing of solid bricks as an alternative to hollow bricks. The research shows the possibility of using this type of concrete in the manufacturing of certain types of bricks used for ceiling slabs instead of hollow bricks to avoid water leakage and moisture storage within concrete ceilings, which results in problems. The research discusses part of these issues related to surface moisture and the possibility of avoiding them.

High-Resolution Target Detection in TDMA-MIMO FMCW Millimeter-Wave Radar Systems
type: item
description: This paper discusses the integration of Time Division Multiple Access (TDMA) with MIMO (Multiple Input Multiple Output) techniques in FMCW millimeter wave (mm-Wave) radar systems for high-resolution target detection and imaging. Through the proposed TDMA-MIMO, we demonstrate that the system can form a virtual antenna array, which significantly improves the angular resolution in range, and Doppler-azimuth-elevation domains. Challenges, including side lobe artifacts, phase errors, and Doppler ambiguity, are mitigated through advanced signal processing methodologies, specifically employing Iterative Peak Component Elimination (IPCE) and Constant False Alarm Rate (CFAR) algorithms. From the experiments carried out, the radar is shown to be able to resolve targets with the use of IQ signal analyses, range-azimuth spectrum imaging, and range-Doppler distribution mapping. moving target detection was accomplished using adaptive thresholding and non-coherent accumulation techniques, showcasing the effectiveness of the proposed framework. These advancements illustrate the system's potential use in scenarios that require precise spatial and velocity parameter estimation, such as security monitoring or aircraft tracking.

type: item
description: Exposing hidden objects and metals to airport safety has become a serious challenge, especially with the increasing development of smuggling techniques and the limitations of traditional safety methods such as X-rays and metal detectors. The study looked at the use of millimeter wave radar (MMW) in conjunction with artificial intelligence (AI) to detect hidden objects in the airport environment in real time. MMW radar, which is known for its ability to penetrate various materials, is used to take radar signals from various hidden objects including metals, metals and non-metallic elements. Captured radar data is processed and analyzed using MATABs, particularly with AI-based models, particularly convolutional neural networks (CNNs) and support vector machines (SVMs) to classify and identify these objects based on their unique radar signatures. This study provides a detailed methodology for data collection, pre-processing, feature extraction, and AI model training, and evaluates the performance of the proposed system in terms of detection accuracy, accuracy, and memory. These results reflect the ability of MMW radar and artificial intelligence devices to significantly improve airport security and provide a non-invasive, fast and reliable way to detect hidden objects, bridging the limitations of existing security screening technologies. Future work will focus on improving model performance, expanding datasets, and integrating real-time processing capabilities for large-scale deployment in operational airport environments.

The Evolution of Electrical Grid Systems from Centralized to Decentralized Networks
type: item
description: The evolution of electrical grid systems from centralized to decentralized networks marks a significant transformation in the energy sector. Traditionally, centralized grids, with power generated at large facilities and transmitted over long distances, have been the norm. However, the increasing demand for sustainable, resilient, and flexible energy solutions has spurred a shift toward decentralized networks. These decentralized grids distribute electricity generation across multiple, often renewable, sources closer to the point of use, reducing transmission losses and enhancing grid reliability. This paper explores the historical development of centralized grids, the driving forces behind the move toward decentralization, and the benefits and challenges associated with decentralized systems. By examining technological advancements, policy changes, and the economic and social implications, the paper provides a comprehensive analysis of the future of electrical grid systems and the potential for decentralized networks to become the new standard in energy distribution.
