Comparing and Contrasting The Heritage Identity of Iraqi Architecture to That of Arab Universities. (Developing and Applying the Concept of Innovation for Architecture Students)
type: item
description: University architectural education generally seeks to graduate a number of architects with the need of the labor market. Most of the study plans contain a number of method of teaching, that forms the architectural thoughts of students. Despite the student learning from the heritage of his country through the educational courses he studies, such as the history of architecture and structure materials &others, However, the rapid technological progress in the means of communication contributed greatly to more knowledge of the scientific developments at the architectural field. The question remains to what extent the students’ trends in designing their projects during their study period are affected by the architectural cultural heritage and educational versus the factors that affect the thought directions of architects and designers in each of Iraqi cities such as Mosul, Baghdad and Salah al-Din. Concerned universities contain in describing some of their courses the concepts of heritage architecture, and the percentage of students’ orientation in their graduation projects towards using the vocabulary and content of the urban heritage was few, and the sample members are more supportive of the need to preserve heritage architecture through the use of its vocabulary and contents in their projects. The study’s problem is The lack and weakness of cultural concepts in the architectural departments, which are concerned with heritage architecture and its vocabulary and its cultural and scientific appeal, which in turn is reflected in the lack of local heritage architectural production and the tendency of local architecture towards alienation despite development and modernity The Study’s Questions is Does heritage architecture negate sufficient interest in the educational process and its outputs in a way that contributes to preserving the cultural and architectural heritage of this nation? The result of this study is that the most important factors affecting their intellectual d…

Mechatronic Control of A Car Cooling System
type: item
description: This article examines the modeling of passenger car internal combustion engine cooling systems based on mechatronic control. In this work, the mechatronic engine cooling system of a passenger car was studied using a mathematical model. The dynamics of the cooling system were described using heat balance equations and modeled using MATLAB/Simulink. In the study, the effect of the cooling fan on the process was taken into account through the radiator heat transfer coefficient. Based on the developed model, four control strategies were analyzed and compared: conventional thermostat control, ON/OFF electronic control, PID control, and Lyapunov-based control. The simulation results show that conventional and ON/OFF methods exhibit larger temperature deviations and oscillations, while the PID and especially the Lyapunov-based controller ensure faster and more stable convergence of engine temperature to the desired value. The obtained results confirm that the application of advanced mechatronic control algorithms significantly improves the thermal regulation and stability of automotive cooling systems.

Application of a Hybrid EKF-Bayesian Approach for Technical Condition Diagnostics of Gas Turbine Auxiliary Power Units
type: item
description: Ensuring the technical reliability and flight safety of gas turbine Auxiliary Power Units (APUs) is a critical task in aviation engineering. Traditional diagnostic methods, often reliant on visual inspections and fixed thresholds, are limited in detecting internal or early-stage faults. This study proposes a proactive hybrid diagnostic approach integrating the Extended Kalman Filter (EKF) and Bayesian Inference for real-time monitoring and fault forecasting of the APU. The EKF is employed to linearize nonlinear engine dynamics and filter stochastic sensor noise, while the Bayesian framework provides a recursive mechanism for fault probability estimation and classification. Experimental results based on 120 test cycles demonstrate that the EKF algorithm reduces the Root Mean Square Error (RMSE) of critical parameters (rotor speed, exhaust gas temperature, and oil pressure) by an average of 65–67% compared to traditional measurement methods. The subsequent Bayesian classification achieved an overall diagnostic accuracy of 95.83% and a sensitivity of 95.0%. Furthermore, Receiver Operating Characteristic (ROC) analysis yielded an Area Under the Curve (AUC) of 0.956, confirming the high discriminatory power of the proposed model. The findings indicate that the integrated EKF-Bayesian approach offers a mathematically rigorous and effective solution for the early detection and trend forecasting of malfunctions, significantly enhancing aviation safety standards.

Review the Behavior of eccentrically loaded RC Columns Strengthened using CFRP Bars and Sheet
type: item
description: This literature review highlights the use of Fiber-Reinforced Polymer (FRP) composites to strengthen reinforced concrete (RC) columns under various loading conditions. It focuses on two main methods: near-surface mounted (NSM) FRP reinforcement and external FRP confinement, often used in combination. Key findings indicate that NSM FRP enhances flexural capacity and seismic performance, particularly under eccentric and biaxial loads. In contrast, external FRP confinement improves axial load capacity but is less effective with increasing eccentricity. Hybrid systems, which integrate NSM FRP and external wraps, effectively mitigate debonding and buckling, enhancing strength and deformation capacity. The review also mentions analytical models that predict the behavior of FRP-strengthened columns. Applications of these methods include corroded, fire-damaged, or seismically challenged columns, confirming FRP composites as a valuable solution for reinforcing concrete structures.

Assessment of the Impacts of Atmospheric Temperature and Pressure on Solar Irradiance in Idah, Kogi State, Nigeria
type: item
description: This study assessed the impacts of atmospheric temperature and pressure on solar irradiance in Idah, Kogi State, Nigeria. That data of atmospheric temperature and pressure were collected hourly from 9:00 am to 6:00 pm on February 25, 2026, in a school called Mathson School, Idah, using a weather station, while solar irradiance was measured using a pyranometer software installed on a laptop, and connected to the internet. The results revealed that the solar irradiance varied throughout the day, with peak values occurring in the early afternoon, which corresponds to higher temperatures and lower atmospheric pressures. The correlation analysis showed that there was a weak positive relationship between temperature and solar irradiance (r = 0.065) and a very weak negative relationship between pressure and solar irradiance (r = –0.036). This correlation despite the weak relationship shows that the solar irradiance is directly proportional with the atmospheric temperature and inversely with the atmospheric pressure. These findings demonstrate that atmospheric conditions have influence on solar irradiance and this provide insight into local solar energy potential. In addition, the results provide an insight regarding the period of time in which higher solar energy is expected in this research area, Idah, Kogi state. It was concluded that though, the correlation coefficients between the solar irradiance with the atmospheric temperature and pressure are low, there exists a relationship between solar irradiance and the two atmospheric parameters considered in this work. It is recommended that solar energy systems in Idah be designed to utilize peak solar irradiance periods between 11:00 am and 3:00 pm. It is also recommended that data of many days or months be used for the similar work in future. Additionally, continuous monitoring of atmospheric parameters should be implemented for improved solar energy planning. This study is valuable as it will inform solar energy forecasti…

Robust Lane Detection Framework for Autonomous Vehicles Using Deep Learning and Computer Vision
type: item
description: The arrival of self-driving cars has made it even more important to have reliable and effective lane detection systems. Lane detection helps keep cars in their lanes while driving, making roads safer. This paper proposes a framework for real-time lane assistance comprising lane detection, tracking, marking recognition, and a warning when the vehicle is about to leave the lane. The framework uses OpenCV and convolutional neural networks (CNNs) to analyze video from a vehicle-mounted camera and estimate lane parameters such as position, slope, and curvature. These parameters let the framework determine the vehicle's position relative to the lane and steer it. Lane detection systems for self-driving cars must work in real time, adapt to varying weather and lighting conditions, and handle changes in road markings. The proposed framework effectively addresses these challenges and improves the safety and reliability of autonomous driving.

Experimental Investigation of Heating Element Performance with Bypass Tubes
type: item
description: This study presents an investigation of the thermo-hydraulic performance of a rotary air preheater heating element utilizing bypass tubes and wire coiled coil matrix turbulators. The work purpose is to improve heat transfer efficiency and minimize flow resistance while considering the practical problems observed in failed heating elements utilized in industrial units such as the Al-Hartha Thermal Power Station in southern Iraq. The experimental setup is intended for simulating working conditions of an air preheater under cyclic charging and discharging of hot and cold air flows. Air from a single matrix is switched between the two directions of flow using a valve-controlled system driven by an automated control panel. Three different types of bypass layout are tested in order to determine the best positioning and number of the tubes. Additionally, bypass tubes with various diameters (10, 15 and 20 mm) and shapes (circular and squared section) are tested. Also, three turbulators with different pitches are inserted into the bypass tubes to increase turbulence and enhance convective heat transfer. The results clarify the interlinked influences of bypass flow control and turbulent augmentation on the overall performance of stack heat recovery elements. The thermo-hydraulic performance for inline-tube arrangement rises on the order of 7.58% over the conventional element, while the 15 mm tubes deliver improvement of 15.47%. The cylindrical section outperformed the square section over examined Re range, with an improvement 23.49%, while the 5 mm pitch turbulator achieved an improvement of 23.92%.

IoT-Enabled Embedded System for Rash Driving Detection and Automatic Speed Control Using GPS and GSM
type: item
description: The loss of human life is the most significant loss that cannot be regained, in contrast to other property losses. Every year, a lot of people die in car accidents. Many different things have been tried to stop these road accidents. There are now better roads, and many road safety programs have been put in place. Many different technologies and methods have been developed to teach people to drive safely, but most haven't helped prevent accidents. The proposed system for this project monitors several vehicle parameters, including speed, engine speed, brake pedal status, and steering angle. An embedded microcontroller board measures all of these things. The goal is to learn about a driver's driving style by looking at how they use the gas and brake pedals. If the way a person drives meets the criteria for reckless driving, the system notifies the driver and, if the behavior continues, limits the vehicle's speed and sends a text message to the nearest police control room via a GSM module. The system also controls how fast cars can go in areas with a lot of people, such as cities and villages along the route. The GPS module system keeps track of the vehicle's location at all times. If it enters a city, the speed limit is set to a safe level.

Low-Temperature, Low-Metal Consumptıon Thermosıphone Heatıng Devıce wıth Intermedıate Heat Carrıer for Solar Heatıng Systems
type: item
description: This study focuses on the development of a low-temperature, low-metal consumption self-regulating thermosiphon heating device with an intermediate heat carrier for solar heating systems aimed at improving energy efficiency and reducing material consumption. The research involves analysis of modern heating device designs, theoretical and experimental investigation of single- and two-phase heat exchange processes, and the development of mathematical models describing evaporation and condensation under natural thermosiphon circulation conditions. The proposed design consists of a hermetic housing divided into evaporation and condensation chambers equipped with steam confusors, ejectors, and a thermoregulating valve, which intensify heat transfer by increasing steam velocity and enhancing mixing in the condensation zone. Hydraulic separation from the main heating system reduces internal pressure and wall thickness, lowering metal consumption while maintaining structural reliability. The results show that the developed device improves heat transfer efficiency and enables 3–4% heat savings through self-regulation, making it suitable for application in solar heating systems and modern energy-saving technologies.

A Water Heater That Regulates Itself for Solar Heating Systems
type: item
description: A method for calculating the water intermediary in a multilayer stratified thermal storage tank used in solar heating and hot water supply systems has been developed. The intermediary has a constant cross-section and uniform perforation throughout its height. The examination of global and domestic practices for improving the performance of self-regulating active water heat accumulators in solar heating systems is ongoing. Innovative solutions for self-regulated stratified thermal storage systems are being developed. Conditions for achieving self-equilibrium in the self-regulatory components of hot water storage tanks are being identified, considering dynamic processes caused by unbalanced solar radiation. A theoretical investigation of water flow in perforated distributors with a constant cross-section under the influence of volume forces is being conducted. Additionally, a theoretical analysis of water collection in perforated collectors with constant cross-sections due to volume forces is taking place. A method for calculating water distribution and designing a self-regulating thermal storage system is currently being developed. An experimental exploration of the perforation in the water distribution system of a self-adjusting hot water storage tank is also underway.

Enhancing the Thermal Performance of a Three-Pass Solar Air Heater Using Latent Heat Storage Materials: A Comprehensive Review
type: item
description: with latent heat storage materials (Phase Change Materials, PCMs) are reviewed to improve the thermal conductivity. The principle behind this integration is based on the high energy-storage density of PCMs, whose heat absorption and heat release occur at nearly constant temperatures, that enhances the system efficiency and smooths the convergence of the outlet air temperature. The enhancement of the air residence time and heat transfer rate is achieved by the three-pass flow pattern although more pressure drop and design complexity are introduced. A review of literature reveals that the use of PCMs brings about considerable improvement in the total thermal performance as compared to the conventional systems more so by way of prolonging the heating duration beyond the retardation of solar radiation. Proper PCM melting temperature and high thermal conductivity of PCM are important for efficient charging/discharging processes Major obstacles are the low thermal conductivity of typical PCMs which generally needs to be enhanced by means of ﬁns, metal matrices or by encapsulation methods. The core technical difficulties are the very low thermal conductivity of the ordinary PCMs, which usually needs to be enhanced by fin, metal matrices, or encapsulation methods. Leakage during melting and long-term material stability are also importantly design issues. Moreover, the hydrodinam¬ics of the three-pass configurations becomes increasingly intricate., thus rendering the airflow distribution and pressure drops as the dominant system optimization parameters. The literature on PCM incorporated three-pass heaters is still scarce, as the most of the works related to that of single- or double-pass collectors. There are important gaps in dynamic modeling of multi-pass systems with PCM, long-term cycling studies, and cost – benefit analyses. The review emphasizes the requirement of development of advanced numerical models, superior PCM composites with enhanced conductivity and system l…
