Data-Driven Analysis of Solar Energy Harvesting Systems: Performance Assessment, Environmental Influences, and Future Perspectives
type: item
description: Solar photovoltaic (PV) systems have emerged as an important part of the global energy transition in the face of increasing demand for sustainable and clean energy solutions. But the environmental conditions greatly affect the performance of solar energy harvesting systems, which require detailed analysis with the support of data for better efficiency and reliability in the operation of such systems. This research introduces a data-driven evaluation of solar energy harvesting systems based on a combined solar PV generation and weather sensor information from two solar power plants. Key operational factors such as the DC power, AC power, daily yield and total yield were analysed together with the environmental factors such as solar irradiation, ambient temperature and module temperature. Performance evaluation of the system was carried out using descriptive, comparative and correlation analysis to study the impact of environmental factors on photovoltaic energy generation. The findings showed that solar irradiation is the most important factor influencing power output as it has a high positive correlation with the photovoltaic (PV) generation. Also, it was determined that the ambient and module temperature had an influence on the system efficiency – which might lead to a decrease in actual performance if the module temperature rises. It was observed that the operational characteristics of both solar plants are similar and environmental conditions play a significant role in determining the energy harvesting results. The results show the potentials of data-driven solutions in photovoltaic performance assessment and renewable energy optimization

A Data-Driven Investigation of Factors Influencing Compressive Strength in Ultra-High-Performance Concrete
type: item
description: Ultra-high-performance concrete (UHPC) exhibits exceptional mechanical performance, durability, and long-term serviceability; however, its compressive strength is governed by numerous interacting mixture-design and curing variables. Conventional experimental optimization is often time-consuming and resource-intensive, creating a need for interpretable data-driven approaches capable of supporting material design and performance prediction. This study investigated the factors influencing UHPC compressive strength and developed a predictive framework for identifying the dominant variables affecting strength development. A cleaned secondary dataset containing 626 UHPC mixtures, 24 predictor variables, and one compressive-strength target variable was analyzed. Exploratory analysis and Pearson correlation were used to examine variable relationships. A Random Forest regression model was developed using an 80:20 train-test split and evaluated using the coefficient of determination (R²), mean absolute error (MAE), root mean square error (RMSE), and five-fold cross-validation. Feature importance and partial dependence analyses were subsequently employed to interpret the contribution of individual variables. The Random Forest model achieved strong predictive performance, with a test R² of 0.9041, MAE of 7.79 MPa, RMSE of 11.09 MPa, and a mean five-fold cross-validation R² of 0.9178. Curing time emerged as the most influential variable, contributing 57.4% of the total feature importance. Sand content showed the strongest negative influence, while silica fume content, cement content, steel fiber content, and superplasticizer content also contributed to prediction accuracy. The findings demonstrate that interpretable machine learning can accurately predict UHPC compressive strength while revealing the relative influence of key mixture-design variables, providing useful guidance for future UHPC design and optimization.

Explainable Hybrid Ensemble Learning for Sustainable Concrete Compressive Strength Prediction and Mix Design Optimization
type: item
description: Accurate prediction of concrete compressive strength is essential for ensuring structural reliability while promoting sustainable construction practices through the efficient utilization of supplementary cementitious materials. This study proposes an explainable machine learning framework for predicting concrete compressive strength and optimizing sustainable concrete mix designs using a dataset comprising 1,030 concrete mixtures. Following data preprocessing and feature engineering, several machine learning algorithms, including Linear Regression, Support Vector Regression, Random Forest, Gradient Boosting, Extra Trees, LightGBM, and XGBoost, were evaluated. The results demonstrated that XGBoost achieved the highest predictive performance, attaining an R² value of 0.9205, MAE of 3.0829 MPa, and RMSE of 4.4687 MPa. To enhance model interpretability, SHapley Additive exPlanations (SHAP) were employed to quantify the influence of input variables on compressive strength predictions. The explainability analysis revealed that curing age, water-binder ratio, and binder content were the most influential factors governing strength development. Furthermore, a sustainability-oriented optimization framework was implemented to identify environmentally favorable concrete mixtures with reduced cement consumption and increased utilization of fly ash and blast furnace slag. The optimal sustainable mixture achieved a sustainability score of 0.736 while maintaining a predicted compressive strength of 33.22 MPa. The findings demonstrate that explainable machine learning provides a reliable and interpretable decision-support tool for sustainable concrete design, contributing to low-carbon construction and resource-efficient infrastructure development.

Machine Learning-Based Water Pollution Prediction for Sustainable Environmental Monitoring
type: item
description: Pollution of water and the decreasing supply of clean drinking water have now become one of greatest environmental and human health issues in the world. The conventional methods of water quality assessment are usually costly, time-consuming and ineffective in continuous environmental monitoring. Here, the current paper examines application of machine learning techniques in predicting water potability using physicochemical water quality indicators. The authors used a publicly available dataset of 3276 water samples with nine environmental factors, including conductivity, organic carbon, trihalomethanes, pH, hardness, solids, sulphate, chloramines, and turbidity. Several monitored ML algorithms, which included; LR, Decision Tree, Random Forest, Support Vector Machine and K-Nearest Neighbor, were comparatively tested in terms of predictive performance. Mean imputation, feature scaling, and exploratory data analysis methods were applied to the data to prepare it before the development of the model. The results showed that SVM had highest accuracy, whereas the Decision Tree model had the most balanced classification results in terms of the F1-score. The most influential predictors of water potability were found to be pH, sulfate, solids, and hardness through feature importance analysis. The findings emphasize the suitability of ML methods in assisting intelligent environmental surveillance, sustainable water resources, and systems of early contamination. The research has a contribution to the increasing role of artificial intelligence to the environment and offers meaningful implications to policy-makers, smart cities, and health agencies.

Machine Learning for Predicting Hydrogen Storage Capacity: Uncovering Key Material Descriptors Governing Metal Hydride Performance
type: item
description: Amongst the various means of hydrogen storage, metal hydride storage with solid-state is considered the most promising way for safe and efficient hydrogen utilization. But, identifying the storage capacity governing descriptors remains a major challenge simply because of complex thermodynamic and compositional effects. This study aimed to predict hydrogen storage capacity in metal hydride materials and identify the key descriptors influencing material performance. A cleaned dataset of 741 observations representing 713 unique metal hydride compositions was analyzed. Hydrogen storage capacity was modeled using Linear Regression, Random Forest, and Gradient Boosting. Predictor variables included material class, heat of formation, entropy of formation, logarithmic equilibrium pressure, and H/M ratio. Model performance was evaluated using MAE, RMSE, and R², while Random Forest feature importance was used to interpret descriptor contributions. Gradient Boosting achieved the best predictive performance, with MAE = 0.1457, RMSE = 0.2400, and R² = 0.8634. Random Forest also performed strongly, with R² = 0.8590, while Linear Regression achieved R² = 0.7978. Feature importance analysis identified the H/M ratio as the dominant predictor, accounting for 47.0% of total importance, followed by the Mg-based material class at 36.7%. Together, these variables contributed approximately 83.7% of total predictive importance. Interpretable machine learning can effectively predict hydrogen storage capacity and reveal descriptor-level insights for metal hydride screening. The findings highlight the importance of hydrogen accommodation capacity and material class in guiding future hydrogen storage material design.

Unsupervised Detection of Abnormal Operating Regimes in Industrial Centrifugal Pumps Using Multivariate Condition Monitoring Data
type: item
description: Industrial centrifugal pumps are critical assets in industrial facilities, where abnormal operating regimes can adversely affect reliability, maintenance efficiency, and process continuity. This study investigated the detection and characterization of abnormal operating regimes in industrial centrifugal pumps using multivariate condition monitoring data and an unsupervised learning framework. A dataset comprising 173,730 observations collected from three centrifugal pumps was analyzed through a workflow that included data preprocessing, sensor-data quality assessment, descriptive statistical analysis, correlation analysis, Isolation Forest-based anomaly detection, and statistical validation. Five operational variables—motor vibration velocity, motor peak acceleration, pump vibration velocity, pump peak acceleration, and outlet pressure—were used for anomaly detection modelling. The results revealed that anomalies were concentrated within specific operating periods rather than being uniformly distributed across the dataset. Pump B on 30 October 2024 exhibited the highest anomaly percentage (59.09%), followed by Pump A on the same date (41.11%), whereas Pump C on 30 October 2024 showed no detected anomalies, indicating a stable inactive operating state. Correlation analysis further demonstrated strong relationships among vibration, acceleration, and pressure measurements, reflecting interconnected mechanical and hydraulic behavior. Anomalous operating conditions were primarily characterized by substantial increases in motor peak acceleration, pump peak acceleration, and outlet pressure. These findings demonstrate that unsupervised anomaly detection can effectively identify abnormal operating regimes in centrifugal pumps without requiring labelled fault information. The proposed framework offers a practical and scalable approach for industrial condition monitoring and supports maintenance decision-making in data-rich operational environments.

ENGINEERING-BASED ASSESSMENT OF FOREST FRAGMENTATION AND LANDSCAPE CONNECTIVITY FOR SUSTAINABLE ENVIRONMENTAL MANAGEMENT
type: item
description: Forest fragmentation is a threat to continuity in the ecosystem, causes greater edge effect and decreases forest landscape structure. Engineering analysis of fragmentation indices will help in sustainable environmental planning by recognizing landscape connectivity influences. This study aimed to assess how forest fragmentation indicators influence landscape connectivity and to evaluate regional variation in forest structural continuity. A quantitative secondary-data design was applied using landscape-level forest fragmentation metrics. Descriptive statistics were used to summarize major variables, Pearson correlation analysis examined relationships among fragmentation indicators, and multiple linear regression evaluated the influence of patch density, edge density, aggregation index, and forest cover on landscape connectivity. Country-level comparison was also performed to identify regional differences. Landscape connectivity showed moderate structural continuity across the analyzed forest systems. Aggregation index had the strongest positive association with connectivity, while patch density and edge density negatively influenced connectivity. The regression model explained 57.3% of the variation in landscape connectivity, confirming that spatial configuration is a major determinant of forest structural cohesion. Country-level results showed clear regional variation, with some countries maintaining stronger connectivity and others showing greater fragmentation pressure. Forest connectivity depends more strongly on patch arrangement than forest cover alone. Sustainable environmental management should prioritize aggregated forest structures, ecological corridors, and the reduction of excessive edge formation to improve landscape continuity.

type: item
description: Efficient hydrogen storage remains a major challenge in the development of sustainable energy systems. Metal hydrides have emerged as promising solid-state hydrogen storage materials because of their favorable thermodynamic stability and reversible hydrogen absorption behavior. This study aimed to predict hydrogen storage performance in metal hydrides using machine learning techniques and to identify the variables most strongly influencing Hydrogen Weight Percent. A quantitative computational framework was implemented using secondary thermodynamic data containing 772 observations and 13 variables. Data preprocessing included missing-value treatment, categorical encoding, and feature scaling prior to model development. Three regression algorithms, namely Linear Regression, Random Forest, and Gradient Boosting, were evaluated using R-squared, mean absolute error, root mean square error, and five-fold cross-validation. The results showed that Gradient Boosting achieved the highest predictive performance with an R squared value of 0.9088, a mean absolute error of 0.1182, and a root mean square error of 0.2194. Random Forest also demonstrated strong predictive capability, whereas Linear Regression produced comparatively lower accuracy. Cross-validation results confirmed the robustness and generalization capability of the ensemble learning models. Feature importance analysis revealed that HtoM was the most influential predictor, contributing 57.77% of the total model importance, followed by Material Class, Temperature oC, and Pressure Atmospheres Absolute. The findings demonstrate that machine learning provides an efficient computational approach for hydrogen storage prediction and supports accelerated screening of metal hydride materials for sustainable energy applications.

PERFORMANCE ANALYSIS OF SOLAR PHOTOVOLTAIC SYSTEMS UNDER VARIABLE ENVIRONMENTAL CONDITIONS
type: item
description: In this study, the performance of a solar photovoltaic crystalline silicon system is evaluated under different environmental conditions. The primary aim was to study the effect of solar irradiance, ambient temperature, PV panel temperature, relative humidity, wind speed and dust condition on PV power output, PV power conversion efficiency and PV performance ratio. The outdoor operating conditions were recorded, such as the voltage, current, power output, irradiance, temperature, humidity, wind speed, and dust level. The results indicated that solar irradiance was found to be the most significant factor among the various factors studied for PV power generation. The maximum irradiance obtained was 910 W/m2, recorded at 01:00 PM and when the maximum power output was obtained at 199.12 W. The maximum conversion efficiency of the panel was however obtained at 09:00 AM when the panel temperature was low of 14.67%. The PV efficiency decreases with the excessive heating as the highest panel temperature of 58.3°C was recorded with the lowest efficiency of 13.68%. The increases in dust accumulation, relative air humidity also contributed to the loss in performance and the wind speed had a moderate cooling effect. The highest energy generation and highest performance ratio was observed during clear sky conditions as observed on a daily basis. The study concludes that to achieve the best performance of solar PV under real environmental conditions regular cleaning, appropriate ventilation, installation angle and constant monitoring are necessary.

EXPLAINABLE ENSEMBLE MACHINE LEARNING FRAMEWORK FOR PREDICTING DRUG RELEASE BEHAVIOR IN POLYMERIC LONG-ACTING INJECTABLE SYSTEMS
type: item
description: Predicting drug release from polymeric long-acting injectable systems remains challenging because release behavior depends on nonlinear interactions among formulation, physicochemical, and temporal variables. This study developed an explainable ensemble machine learning framework for predicting drug release behavior and identifying the most influential release-governing variables. A secondary experimental dataset containing 3,783 observations and 20 variables was analyzed. Data preprocessing included quality inspection, categorical encoding, exclusion of identifier variables, and train-test splitting. Linear Regression, Random Forest, and XGBoost models were developed and evaluated using R², mean absolute error, and root mean square error. Feature importance and residual analyses were additionally performed to assess interpretability and model reliability. XGBoost achieved the best predictive performance with an R² of 0.9849, MAE of 0.0276, and RMSE of 0.0406, outperforming Random Forest and Linear Regression. The strongest predictors were T = 1.0, Drug NHA, SE, Drug Mw, and Time. Residual analysis demonstrated low prediction bias and stable error distribution, supporting the robustness of the optimized model. The findings indicate that explainable ensemble learning can accurately model complex release behavior in polymeric long-acting injectable systems and may support efficient formulation screening, optimization, and data-driven pharmaceutical engineering.

PREDICTIVE ASSESSMENT OF CONCRETE COMPRESSIVE STRENGTHUSING MIX DESIGN PARAMETERS AND ENGINEERED CEMENTITIOUSFEATURES
type: item
description: Concrete compressive strength is a key indicator of concrete quality, structural performance, and suitability for construction applications. This study presents a predictive assessment of concrete compressive strength using mix design parameters and engineered cementitious features. The analysis was based on 1,030 concrete mix records containing cement, slag, fly ash, water, superplasticizer, coarse aggregate, fine aggregate, curing age, compressive strength, and derived features including water-cement ratio, total binder content, aggregate-to-cement ratio, cement-water interaction, and age-strength proxy. Descriptive analysis showed that compressive strength ranged from 2.33 MPa to 82.60 MPa, indicating broad variation across low-, medium-, and high-strength concrete mixtures. Correlation analysis revealed that total binder content, cement content, age-strength proxy, superplasticizer, and curing age were positively associated with compressive strength, while water-cement ratio, aggregate-to-cement ratio, and water content showed negative relationships. Five regression models were evaluated, including Linear Regression, Decision Tree Regression, Random Forest Regression, Gradient Boosting Regression, and Support Vector Regression. The results showed that non-linear models outperformed Linear Regression, with Random Forest Regression achieving the highest predictive performance with an R² value of 0.908. Feature importance analysis identified total binder content, curing age, age-strength proxy, and water-cement ratio as the most influential predictors. The findings demonstrate that engineered cementitious features can improve strength interpretation and support preliminary concrete mix assessment, quality control, and construction decision making.

SURVIVAL ANALYSIS OF BREAST CANCER PATIENTS USING CLINICAL RISK PARAMETERS: A STATISTICAL APPROACH BASED ON TIME-TO-EVENT MODELLING
type: item
description: Background: Breast cancer continues to be a major health concern, where patient survival is influenced by multiple clinical and physiological factors. Understanding the relationship between these factors and survival outcomes is essential for improving patient management and early intervention strategies. Objective: The present study aims to evaluate the survival patterns of breast cancer patients and to examine the influence of selected clinical parameters on time-to-event outcomes using appropriate statistical modelling techniques. Methods: The study is based on secondary clinical data collected from 500 breast cancer patients who underwent routine health assessment. Key variables considered include age, body mass index (BMI), heart rate (average), position score (average), systolic and diastolic blood pressure (average), oxygen saturation (average), medical progression score (average), and symptom severity score (average). Survival analysis was carried out using the Kaplan–Meier estimator to estimate survival probabilities, the Cox proportional hazards model to identify significant predictors, and the Nelson–Aalen estimator to assess cumulative hazard. Model performance was evaluated using the concordance index and likelihood-based measures. Results:The median survival time was estimated to be 2.2 hours, indicating early occurrence of events within the study period. The Cox regression analysis revealed that BMI, systolic blood pressure, position score, medical progression score, and symptom severity score have a statistically significant effect on survival outcomes. Among these, medical progression score showed a strong positive association with risk, while symptom severity score demonstrated a protective effect. The concordance index value of 0.66 indicates moderate predictive performance of the model. The cumulative hazard analysis showed a steady increase in risk over time, with a noticeable rise in later intervals. Conclusion: The findings confirm that surviv…

SEISMIC ANALYSIS OF SKEW CURVED BRIDGES FOR ZONE 4 SEISMOLOGY
type: item
description: Due to the complex behavior of bridges at this level of seismic failure, skewed-curved bridges constitute a severe challenge to structural engineering. They are different from straight bridges in that the combined form of these two curves and angles results in a clear gap between the center of mass and the center of rigidity. So that gives the rock a "pinball" effect in an earthquake. In zones like Zone 4, which experience much severe ground movement, these bridges encounter issues such as excessive deck rotations, pounding between decks and abutments, and risk of falling off their supports. Using Nonlinear Time History Analysis (NLTHA), a new approach is proposed for understanding how such structures react dynamically, with particular emphasis given to their curvature radius and effect on performance. Curvature and skew angles push up the shear forces on piers and cause bigger movement in expansion joints. Following IS 1893:2002 guidelines, the study identifies some key failure modes, such as the "kick" effect at abutments. Its focus is to draw attention to demand for some type of the latest seismic isolation or restraint system to prevent collapse in earthquake-prone regions. With the transitions (if it doesn't sound boring): the author alters styles and breaks from established patterns.

FABRICATION AND TESTING OF PLASTIC SAND BRICKS
type: item
description: The exponential growth of non-recyclable plastic waste presents a problem for the environment, as the increasing non-recyclable plastics disposal or thermal recycling process frequently exacerbates the effects of climate change and ecological degradation. In this paper, we examine yet another environmentally friendly method, that of plastics for building-grade bricks. In a bid to meet or exceed traditional masonry standards, we synthesized high-density polyethylene (HDPE), quartz sand, and bitumen additives into plastic-sand bricks in a set of bricks. The process was waste to material transition from collection, to decontamination and shredding of PET and HDPE waste. The material was thermally processed at 180°C up to 220°C, mixed with river sand with a weight ratio of 1:2, 1:3 and 1:4. These units differ from regular clay bricks in that they are cold pressed in oiled molds and cured at room temperature, bypassing the carbon-intensive kiln-firing part of the construction process. Empirical testing - compressive strength, water absorption, efflorescence test etc - demonstrated the composite bricks to be structurally better than a clay type. Furthermore, it's worth noting that the plastic binder is non-porous providing negligible water absorption leading to excellent weather resistance. Results, for plastic-sand brick, indicate a combined twofold response: It is a strong and energy-saving construction material, and has useful plastic rubbish recycling utility.

COMPARATIVE ANALYSIS OF MACHINE LEARNING MODELS FOR PREDICTING CONCRETE COMPRESSIVE STRENGTH
type: item
description: Concrete compressive strength is a basic parameter in civil engineering that relates to the quality and longevity of structures. Traditional techniques of measuring compressive strength are based on laboratory tests which are usually time and resource consuming. The paper examines how machine learning methods can be used to estimate compressive strength of concrete in terms of mixture composition and curing age. They used a dataset of 1030 samples reflecting eight input variables; cement, water, aggregates and age. Three machine learning models, all regressions, were implemented: Linear Regression, Decision Tree Regressor, and Random Forest Regressor. The data was split into 80:20 training and testing data. Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE) and coefficient of determination (R2) were used to gauge model performance. The Regressor model that performed better was the Random Forest Regressor which had a R2 of 0.882 with an RMSE of 5.510. The analysis of importance of features showed that the most important factors in the compressive strength prediction are the curing age and cement content. The findings denote that the machine learning models, especially the ensemble-based models, may be useful in forecasting the compressive strength of concrete and provide an effective alternative to conventional experimental techniques.

AN EFFICIENT SCHEDULING ALGORITHM FOR LOAD BALANCING IN CLOUD COMPUTING ENVIRONMENTS
type: item
description: The problem of load balancing has become one of the primary aspects of cloud computing because of the asymmetry of the allocation of duties, which may lead to an inefficient use of resources and breakdown of performance. Despite the various scheduling techniques that have been expounded, there is a desire to continue and have simpler and adaptive techniques, which can be able to operate effectively with huge and dynamic workloads. This study evaluates a load-aware scheduling approach designed to improve workload distribution across virtual machines in a cloud environment. A large-scale task scheduling dataset was preprocessed to construct job-level workloads, resulting in 80,000 jobs for analysis. Jobs were ordered by submission time and assigned to virtual machines in a simulation framework. The proposed method dynamically assigns each incoming job to the virtual machine with the minimum current load. Its performance was compared with First-Come-First-Serve (FCFS) and Round Robin scheduling using load variance, standard deviation, and fairness index. The results show that the load-aware approach significantly reduces workload imbalance, achieving approximately 99.9% reduction in load variance and over 96% reduction in standard deviation compared to both baseline methods. It also attains the highest fairness index, indicating a more uniform distribution across virtual machines. These findings suggest that simple load-aware scheduling can effectively improve resource distribution without introducing additional computational complexity, making it a practical solution for large-scale cloud environments.

type: item
description: The precise forecasting of residential house prices is a significant issue in the real estate industry as it helps in informed decision making by buyers, sellers, and investors. The purpose of the study is to create a machine learning-based model to predict house prices on the basis of a structured housing data. The dataset in this study comprises 545 records with an array of properties, such as area, number of bedrooms, bathrooms, stories, and other housing characteristics. The dataset was prepared by data preprocessing methods like encoding categorical variables and feature selection, to use in modeling. Three machine learning regression algorithms - Linear Regression, Random Forest Regressor and Decision Tree Regressor - were deployed and compared. Evaluation metrics such as Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and coefficient of determination (R2) were used to evaluate the performance of these models. Results show that the Linear Regression model performed better than the rest with R2 of around 0.65 which shows moderate predictive power. The results indicate that machine learning methods can be effective in predicting the prices of residential properties, and it can be used as a valuable tool in the analysis and decision-making of real estate.
