Smart Detection of Low Engagement in Students using Artificial Intelligence andBehavioral Data
type: item
description: This work aims to develop a basic artificial intelligence program that can identify the class's most indolent student. The purpose of the program is to examine specific behaviors that demonstrate a lack of effort. These include missing a lot of classes, arriving late, especially by more than twenty minutes, turning in assignments late, and receiving poor grades. The program evaluates each of these factors for each student and determines which ones fit all the criteria for being lazy. We start by entering each student's information. Their name, number of absences, tardiness on various days, final grade, and whether or not they turned in their work on time are all included in this. This makes it easier to evaluate each student's performance in relation to the class average. It determines whether the student meets each condition using straightforward checks, also known as Boolean logic, such as "true" or "false." A student is labeled lazy if they have missed more than four classes, been late more than twenty minutes at least once, failed to turn in assignments on time, and received a grade below the class average. The program creates a list of the lazy students after evaluating every one of them. It selects the student with the lowest score from this list. The term "laziest" is then applied to that student. The program indicates that no lazy student was found if no student satisfies every requirement. This prevents students from being unfairly judged if they only missed one or two things.

Re-Evaluating the Functionalist Approach of Urban Management towards SustainableArchitecture and Urban Layout with Emphasis on the Role of Digital Technologies
type: item
description: Urban management's persistent reliance on purely functionalist approaches often sidelines aesthetics and social vitality, particularly in sustainable architecture and urban layout. This tension between sociologists prioritizing citizen-centered social functions and architects championing environmental, aesthetic, and symbolic roles undermines holistic urban development. Focusing on Tehran's District 6, this research interrogates how digital technologies can reconcile these perspectives to foster spaces that are efficient, sustainable, and culturally resonant. Through critical literature review and qualitative case analysis, we reveal how decades of functionalist management eroded District 6's visual coherence, social equity, and historical identity. The area's haphazard development, driven by ad-hoc construction and weak oversight, exemplifies the costs of neglecting integrated design. Yet, our findings propose a transformative pathway: strategically embedding digital tools (e.g., geographic information systems (GIS) mapping, Artificial intelligence (AI)-assisted restoration, augmented reality/virtual reality (AR/VR) placemaking, and participatory platforms) within sustainable architecture principles can revitalize urban fabric. We demonstrate that digital integration enables more than technical efficiency---it re-centers human experience. Interactive public spaces, digitally enhanced heritage conservation, and real-time civic co-design tools strengthen belonging while optimizing resource use. However, success hinges on transcending institutional silos and empowering communities. Ultimately, this study argues for an aesthetic-functional hybrid model where digital technology mediates between sociological needs and architectural innovation. For cities like Tehran, this approach isn't optional; it's vital for crafting resilient, identity-rich neighborhoods that honor both people and place.

Hybrid RNN-GRU-LSTM Model for Accurate Detection of DDoS Attacks on IDS Dataset
type: item
description: Distributed Denial of Service (DDoS) attacks are a persistent threat to network security, capable of disrupting critical services. This study proposes a hybrid deep learning model that combines Recurrent Neural Networks (RNN), Gated Recurrent Units (GRU), and Long Short-Term Memory (LSTM) networks to effectively detect DDoS attacks in network traffic. Each component of the hybrid model captures unique temporal dependencies—RNN for basic sequence patterns, GRU for efficient short-term memory, and LSTM for long-term memory retention. The model is evaluated using two standard Intrusion Detection System (IDS) datasets, CIC-DDoS2019 and UNSW-NB15, representing diverse attack scenarios. Preprocessing techniques, including feature selection, normalization, and class balancing with Synthetic Minority Over-sampling Technique (SMOTE), ensure high-quality input data. Experimental results demonstrate that the hybrid model outperforms standalone RNN, GRU, and LSTM models, achieving superior accuracy, precision, recall, and F1-score. Specifically, the hybrid model achieves 97.3% accuracy, 97.0% precision, 97.6% recall, and an AUC of 0.981 on the CIC-DDoS2019 dataset. These results underscore the model’s capability to detect complex DDoS patterns while maintaining low false positive rates. The proposed approach offers a scalable, adaptive, and robust solution for real-time intrusion detection in dynamic network environments, outperforming traditional methods.

Comfort Level and Increased Utilization in Smart Buildings by Promoting Sustainability: A New Hybrid Genetic and Bat Algorithms
type: item
description: The challenge of effectively managing energy consumption in smart buildings has become increasingly significant in recent years. Both macroeconomic and microeconomic frameworks stand to benefit from efficient energy management strategies. Additionally, it is essential to ensure that tenants in smart buildings experience acceptable levels of comfort. By utilizing optimization algorithms, we can minimize energy consumption while maximizing user convenience. In this paper, we propose an agent-based optimization method grounded in a multi-layered architectural framework and its architecture comprises an intelligent agent that communicates with one another within a three-tier network system. Our research specifically focuses on reducing energy consumption costs and peak demand rates while simultaneously enhancing user comfort to the highest possible standard. However, this optimization challenge is notably complex due to the vast array of electrical devices and their varying functionalities. To address this complexity, we propose a hybrid optimization approach that leverages both Genetic Algorithms (GA) and Bat algorithms and evaluated the performance of our method using specific objective functions and drawn comparisons with recent studies on Smart Home and CU-BEM datasets. The switch layer is responsible for monitoring user preferences and comfort levels. The coordination layer features a coordinating agent tasked with determining the optimal scheduling of electrical appliances to achieve cost reductions in electricity consumption while maximizing user comfort. Finally, the execution layer consists of performing agents directly managing device operations. This comprehensive approach seeks to create a more sustainable energy management system in smart buildings, contributing to both economic efficiency and enhanced tenant satisfaction.

Investigation on Optimal Distance between Transmitter and Receiver Coils in Wireless Power Transfer for Dynamic Charging System
type: item
description: The usage of electric vehicles (EVs) has significantly increased because of the worldwide movement toward environmentally friendly transportation. Not withstanding these advancements, creating a comfortable and effective infrastructure for charging EVs remains a significant obstacle to their broad adoption. To overcome this difficulty, wireless power transfer (WPT) technology-specifically, WPT-DCS—has shown promise. With Wireless Power Transfer (WPT)- Dynamic Charging System (DCS), physical connectors are no longer necessary, and EV batteries may be refilled while on the road. In this paper, the development of an optimal distance for wireless power transfer in a dynamic charging system for electric vehicles is proposed. Research that investigated square and circular spiral coils to solve the challenges of WPT-DCS implementation focused on the effects of spiral geometries' thickness as well as the magnetic flux distribution, coupling factor, the receiver (RX) efficiency, RX power, and mutual inductance between TX (transmitter) and RX. Determining the ideal distance between TX and RX and TX and TX is the main goal for dynamic EV charging systems. This paper also presents the hardware setup that replicates the dynamic charging environment for square and circular spiral coils. The concept of emf generation and its utilization for charging the battery while the vehicle is in motion is presented in this paper.

A Systematic Approach for Protective Relay Coordination and Transient Stability Examination in Energy Networks with Substantial DG Penetration
type: item
description: A transient stability examination is crucial in pinpointing the constraints of the electric power systems. On the other hand, the infiltration level of distribution generation influences the constraints in creating safeguards in the power system. Therefore, these two parameters should be regarded as key elements in the power system conservation of the grid. In this work, a transient stability examination of a power system, including DGs, is accomplished to evaluate the protective settings of overcurrent relays (OCRs). For this purpose, the transient stability of DGs is scrutinized under fault conditions at the sites, as well as different DG infiltration degrees. Then, the limitations of DGs in the protective harmonization of OCRs are considered. A novel systematic approach for calculating the modified time multiplier setting (TMS) of OCRs is recommended. The recommended approach maintains coordination among OCRs, and the instability of DG sources is also prevented. Modeling of the IEEE 33 bus system using the ETAP application is used to test the suggested protection scheme's efficacy.

Reducing Switch Count in a Self-Balancing Nine-Level Switched Capacitor Inverter: A Modified Approach
type: item
description: Renewable energy sources are becoming more and more popular to minimize environmental damage while meeting the world's expanding demand for electricity. However, components like DC-AC converters, transformer/inductor absence operation, front-end DC-DC converters with high gain capacity, and high voltage at a selected level are needed for small-scale PV solar independent AC loads and for grid applications as well as. This study offers a step-up boost inverter with quadruple operation of 9-levels that solves the problem by using a switched capacitor approach with less complications. By utilizing the control scheme itself, the topology is intended to balance capacitor voltages without the requirement for sensors. A phase disposition-pulse width modulation (PD-PWM) control technique is employed in this topology. This work focuses on the switching operation modes of the anticipated inverter and presents experimentally confirmed simulation experiments carried out in MATLAB/Simulink. All things considered; this research presents a viable option for renewable energy systems that can assist in satisfying the demand for electricity while preserving the environment.

A Case Study on Optimal Tilt Angle and Spacing for Rooftop Solar Photovoltaic System at Bhubaneswar
type: item
description: The effectiveness of photovoltaic (PV) surfaces in capturing solar energy is influenced by the angle at which sunlight strikes them. To maximize irradiance collection, PV modules should ideally be positioned perpendicular to incoming solar rays. Suboptimal placement can result in diminished system performance, highlighting the importance of installing PV modules at an ideal tilt. Additionally, shadow effects can significantly impact PV array efficiency. This research examines key aspects of PV system installation, with a focus on array positioning in terms of tilt angle and row spacing to reduce horizontal shading. When installing PV arrays, determining the optimal tilt angle is essential for maximizing irradiance reception. Row spacing is calculated to eliminate inter-array shadows. The study presents calculations for optimal tilt angle and spacing, validated through a prototype 11.2 kWp solar photovoltaic system installed at Siksha ‘O’ Anusandhan, Bhubaneswar, India. The research determines monthly and yearly optimal tilts, solar flux gains, and energy yields for this specific location. Findings show a maximum solar flux gain of 32.97% in December, with a Global Solar Radiation (GSR) of 4.72 kWh/m2/day at a 40° optimal tilt. The lowest solar flux gains are observed in July, August, and September. Tilt adjustments during summer months (May to August) increase shading, which contributes to cooling effects.

Deciphering Blood Cells - Method for Blood Cell Analysis using Microscopic Images
type: item
description: Blood cell analysis of RBC and WBC from smear images is crucial for identifying disorders caused by abnormal blood cells, such as leukemia, anemia, frequent infections, and other diseases, including cancer. Pathologists find it challenging to distinguish between abnormal and normal cells in smear images. Manually counting each element is tedious and prone to human errors. Image processing techniques are used to enhance the smear image quality before segmentation. Identifying and segmenting smear images remains a challenge for pathologists. In this research, we propose an approach for identifying and segmenting smear images, followed by classifying normal and abnormal cells. This work implements Mask CNN for segmentation and two different algorithms: EfficientNet-B3 and DenseNet-121 for classification. The Mask CNN model's results for identification and segmentation are evaluated using mAP and IOU. For RBC, the best mAP value is 0.52 and IOU is 0.45. For WBC, the best mAP value is 0.56 and IOU is 0.52. Classification results outperform previous studies, with experiments on six different classes based on RBC and WBC cell normality and abnormality. The average overall accuracy for EfficientNet-B3 is 95% and DenseNet-121 is 97%, respectively.

MPPT For Hybrid Energy System Using Machine Learning Techniques
type: item
description: The share of renewable energy sources (RES) in the total energy production has been growing rapidly. With the improvement in photovoltaic panel design and manufacturing techniques the per unit cost of photovoltaic systems (PVS) generated electricity has dropped considerably. Wind Energy Conversion Systems (WECS) have also seen a steady drop in the per unit electricity generation cost. This along with the environmental benefits of RES has made them a promising technology for power generation soon. To maximize the energy yield we need to operate the PVS and WECS at the maximum power point (MPP). This ensures that at any given moment we extract the maximum possible power from the systems. The PVS and WECS can be combined together to reduce the uncertainty around the availability of any given natural resource (solar or wind) at the given time. This Hybrid System can produce more power per square meter of land and is more reliable than the separate PVS or WECS. In this paper we discuss a machine learning (ML) based approach for faster maximum power point tracking (MPPT) of a hybrid energy system (HES) and its comparison with the conventional Perturb and Observe(P\&O) method.

Impact of Hydrogen Enriched Air and Ethanol-Diesel Fuel Blends on Combustion, Performance and Emission behaviour of CI Engine
type: item
description: The rapid depletion of fossil fuels and harmful tile pipe emissions form internal combustion engines at an alarming rate make the finding for alternative fuels to power the engines. This article investigates the diesel engine capability by the combined effects of ethanol and diesel fuel blending and hydrogen enriched intake air on the performance, combustion, and emission characteristics of 4-stroke diesel engine. These experiments were conducted using three different fuel configurations such as 20% ethanol--80% diesel blend (E20D80), neat diesel (D100), and ethanol diesel blend (E20D80), supplemented with hydrogen enriched air (E20D80+H26LPM). The hydrogen was supplied to engine at constant flow rate of 6 LPM through manifold along with air. Three distinct fuels were used in the engine, and its performance, emissions, and combustion characteristics were assessed under load conditions ranging from 0% to 100%. Hydrogen enrichment of the intake air improves the combustion efficiency of ethanol by accelerating flame speed and enhancing thermal conversion, offsetting ethanol's lower calorific value. A peak in-cylinder pressure of approximately 69 bar was achieved, indicating more effective combustion. CO emissions decreased significantly under part-load conditions due to improved oxidation kinetics. Ethanol's high latent heat of vaporization helped maintain NOx emissions at levels comparable to diesel 1023 ppm. However, a slight increase in smoke emissions was observed with hydrogen addition, possibly due to richer local equivalence ratios and altered combustion dynamics.
