  Identification and long-term temporal sequential change analysis of urban VOCs high-value areas based on GIS and remote sensing ( Free Full-text Access )

  by Xiang Li, Xiang Wang, Wei Peng 
  Abstract: This study systematically identifies key high-emission zones for volatile organic compounds within the Beijing-Tianjin-Hebei urban cluster by integrating geographic information systems spatial analysis with remote sensing inversion models, utilising long-term tropospheric monitoring instrument formaldehyde column concentration data (2005-2022) and Landsat land use data. We specifically developed a spatiotemporal weighted regression model to comprehensively analyse the spatial distribution patterns of volatile organic compounds. Results consistently revealed that urban areas exhibited average concentrations 3.4 times higher than natural background zones, with industrial clusters forming statistically significant emission hotspots. Long-term Theil-Sen trend analysis indicated an average annual decrease of 4.2% in volatile organic compound concentrations after 2013, systematically validating the effectiveness of clean air policies and providing a scientific basis for informed precise management of regional ozone precursors.

  Adaboost algorithm-based cost risk assessment for university laboratory construction ( Free Full-text Access )

  by Pengfei Zhao 
  Abstract: With the rapid expansion of university laboratories, cost overruns have become a critical issue due to accelerating hardware iterations, rising hidden costs, and significant interdisciplinary disparities. Traditional risk assessment methods, such as multiple linear regression and Monte Carlo simulation, struggle to handle nonlinear interactions and data heterogeneity. To address these challenges, this paper proposes a dynamic weight-adjusted AdaBoost algorithm for cost risk assessment. The approach incorporates a multimodal feature fusion mechanism integrating hardware, software, and implicit cost domains, alongside a domain-knowledge guided weighting strategy. Experimental results on a multi-disciplinary dataset show that the proposed method reduces the mean absolute percentage error by 26.5% and improves the F1-score for high-risk event identification to 0.893, significantly outperforming existing benchmarks. The framework also enables earlier risk warnings and more effective cost control strategies.

  Region-specific multi-scale meteorological forecasting based on data assimilation and reinforcement learning ( Free Full-text Access )

  by Zhenhong Sun, Xi Liu, Yicen Liu, Ruohan Li 
  Abstract: Accurate meteorological forecasting is vital for disaster prevention. However, existing approaches often suffer from significant heterogeneity in meteorological data. To address these challenges, this paper introduces a data assimilation method based on particle swarm optimisation and particle filtering to derive assimilated meteorological observation variables. Subsequently, the seasonal-trend decomposition using LOESS is applied to disaggregate meteorological series. The trend component is predicted using a gated recurrent unit model, while the seasonal and residual components are formulated as state variables. This reformulation transforms forecasting problems into the multi-dimensional decision-making task, facilitating the training of a reinforcement learning model to improve forecasting accuracy. Experimental results show that the proposed model reduces the root mean square error by at least 13.93% and 15.21% for forecast lead times of 6 and 24 days, respectively, demonstrating its potential as an effective technical solution for high-precision meteorological forecasting across diverse climatic regions.

• A Hybrid Model of Fuzzy Logic to Enhance Data Mining Accuracy Incorporating Intra-Concentration and Inter-Separability (I2CS) Loss into Neighborhood Component Analysis  
  by Hemangini Mohanty, Santilata Champati 
  Abstract: Data mining is crucial to discovering meaningful insights and patterns from massive datasets. However, the accuracy and efficiency of data mining algorithms are often challenged by the curse of dimensionality and the complexity of real-world data. In this article, we propose a novel approach to enhance the accuracy of data mining by enriching the concept of intra-concentration and inter-separability (I2CS) loss into neighbourhood component analysis (NCA). NCA is a dimensionality reduction technique that focuses on preserving local neighbourhood information, thus improving classification accuracy. Fuzzy logic, on the other hand, provides a flexible framework to handle uncertainty and vagueness in data, enabling more nuanced decision-making. By integrating fuzzy C-means clustering with I2CS-NCA, we aim to leverage the complementary strengths of both approaches to enhance the accuracy and robustness of data mining algorithms. Also, the experimental results show that the proposed model gives the highest accuracy.

• Ensemble of Transfer Learning With Convolutional Neural Networks for Writer Recognition in Historical Documents  
  by Radmila Jankovic Babic, Alessia Amelio, Ivo R. Draganov, Marijana Cosovic 
  Abstract: In the cultural heritage domain, writer recognition has become a challenging classification task still explored for historical documents, due to the presence of different types of noise in the documents, i.e. ink bleed-through, ink corrosion, stains on paper or parchment, difficulty in the character discrimination, elements different from the text, such as images, etc. that limit the effectiveness of existing techniques. To further advance in terms of robustness of classification and experimental setting, we propose a new deep learning model which ensembles pre-trained Convolutional Neural Networks for writer recognition. Specifically, the ensemble is composed of three pre-trained Inception-ResNet-v2 models with different hyperparameter values. Results obtained on the benchmark ICDAR 2019 dataset of handwritten historical documents prove that the proposed approach is very promising in recognizing the handwritten characters of different writers, also when compared with other deep learning models.

• Information fusion method on hexagonal fuzzy number based Multi-Criteria Decision Making problems  
  by Lakshmana Gomathi Nayagam Velu, Bharanidharan R 
  Abstract: Recieving the information from the experts are crucial stage in fuzzy multicriteria decision making (MCDM) problems. Different types of fuzzy numbers are used in fuzzy MCDM problems. Moreover, Hexagonal fuzzy numbers is widely used in fuzzy MCDM problems because of its convenience on piecewise linearity. The major drawback of fuzzy MCDM problems is non-availability of information for some alternatives with respect to some criteria while collecting information from the experts. To overcome this, researchers found some methodologies which are known as information fusion/infusion methods. In this paper, we have proposed two infusion methods based on score functions and similarity measures and studied infusion fusion algorithms by giving illustrative numerical examples. Further, due to the needfulness, a new similarity measure on Hexagonal fuzzy numbers have been introduced and used in the infusion method.

• Rice Plant Nutrient Deficiency Classification Using Deep Learning Techniques  
  by D. Sindhujah, R. Shoba Rani 
  Abstract: Every day, half of the world’s population eats rice. The World Bank predicts that by 2025, the demand for rice consumption will have increased by 51%. Mineral deficiency is one of the variables that impact rice yield. Plants need a variety of minerals and nutrients to flourish, especially while they are in the process of blooming or developing fruit. Critical plant growth disorders, which impact agricultural productivity, are caused by nutrient deficiencies. As soon as farmers see signs of nutrient inadequacy in their plants, they may use effective nutrient management measures to remedy the situation. New possibilities in non-destructive field-based analysis for nutritional deficiencies have emerged with computer vision and deep learning algorithms. In this research, we presented a ResNet50 model that has been fine-tuned to identify nutritional deficits in rice images. Our suggested model is combined with the ADAM optimiser and the softmax classifier to get the best possible outcome. Using our model, we will determine whether the rice plant is deficient in nitrogen, phosphorus, and potassium. Our findings show that our model outperforms the competition with an accuracy of 94.34%.

• Optimizing Feature Selection in Educational Data Sets Using an Enhanced Teaching-Learning Based Optimization Algorithm  
  by George Amalarethinam, A. Emima 
  Abstract: Educational data mining (EDM) is an emerging study topic that helps schools improve student performance. Selecting only relevant data reduces model input parameters with feature selection. It reduces dimensionality by selecting a subset of features and removing incorrect, superfluous, or noisy ones. It improves learning accuracy, computational cost, and model interpretability. This impacts the accuracy of performance models used to assess student outcomes. Most optimisation methods, including the genetic algorithm, must optimise many governing parameters for greater performance. Optimisation approaches using wrapper feature selection (WFS) improve classifier prediction. The proposed ETLBO algorithm with WFS techniques uses the Euclidean distance formula to assess fitness value and popular control parameters to select the optimal feature subset. The algorithm above is used on the educational dataset. Classification algorithms evaluate the best features from TLBO ETLBO algorithms: 4 algorithms classify performance metrics: GNB, LR, SVM, and K-nearest neighbour. Experimental results suggest that the ELTBO algorithm’s best feature subset improves classification accuracy for GNB, LR, SVM, and KNN compared to TLBO.

• Advancing Healthcare Intelligent Systems: The Critical Role of Paternity Benefits in Modern Caregiving  
  by Swapna Ashmi, P.R.L. Rajavenkatesan 
  Abstract: The Maternity Benefit Act of 1961 ensures that women are entitled to receive payment for maternity leave and leave in the event of a miscarriage. It is also important to note that Indian law has not appropriately recognised paternity leave. Fathers can take paternity leave after the birth of their child or after miscarriage, adoption, or similar circumstances. The legislation regarding paternity leave in India was officially passed in 2017. The execution of this law needs improvement, as dads’ paternity leave rights are not regulated. Gender-neutral policy guidelines matter in a global economy. Fathers’ contributions to their spouses and children’s well-being make paid parental leave crucial. The study examines how paternity benefits affect children’s development and growth. The study also compared India’s paternity leave policy to many others. Healthcare analysis and kid well-being are also examined. It was given to 317 people from diverse fields. The study evaluates the importance of paternity benefit enforcement in India based on 250-member replies. MS Office was used to draft and organise the research, while Python was used to process and compare data.

• Ancient Epigraphical Monuments' Convolution Neural Network-Based Skeletonized Structural Angularmorphing Character Identification Intelligent Systems  
  by P. Selvakumar 
  Abstract: Tamil is one of the oldest languages, and it is based on several proofs from ancient Kiladhi epigraphic monuments. Tamil texts have various structural styles and projections identified from monuments like palm lead characters, vattezhuthu, and stone inscriptions. By projecting Tamil characters in various angles, the text style may vary due to structural representation, leading the actual character style to differentiate from the old style. Thus, recognition of the specific projection of the old character leads to more features on the dimension level to get the Tamil character and classification. Consider skeletonized structural angular morphing (S2AM) based on a CNN-identified Tamil character from ancient epigraphic monuments for optimum identification. Epigrammatic images will be pre-processed using Gaussian filters, then SMS will glide the character region using CED. Use the skeletonized angular projection to discover text structural components and extract angular information. The selected features will be trained with a DFCNN to

• Intelligent Techniques for Evaluating Organizational Agility via Contingency Theory in Dynamic Environments  
  by Sivakoti Reddy Manukonda, Seema Bhakuni, Vinayak Anil Bhat, Rameshwaran Byloppilly, Rishi Shukla, Jayesh Solanki 
  Abstract: The contingency approach to management holds that effective management depends on the context of a situation. This paper discusses how the contingency approach works in different managerial settings, focussing on environmental variables like organisational size, task structure, and leadership style that may affect manager effectiveness. This study will combine an in-depth literature review, interview and survey data, and statistical analysis to understand the contingency strategy in practice. Management approaches combined with these environmental variables improved organisational performance, adaptation, and resilience. With organised contingency practices, larger organisations perform better, adaptive management tactics help difficult tasks, and democratic leadership styles work better in varied situations. Regression models and the coefficient of correlation show strong positive correlations supporting these links. Since the contingency technique usually requires ongoing adjustment and integration of various factors into a system, it also highlights its obstacles and limitations from the study. Long-term contingency practices and their effects or

• Predicting Chronic Obstructive Pulmonary Disease (COPD) using Machine Learning with Bio-Inspired Hyperparameter Optimization  
  by Yalin Song 
  Abstract: Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory condition for which early detection is crucial to effective patient management. With LGBM and DTC as the foundational models, this study explores the predictive capability of ML approaches for COPD. Two bio-inspired optimizers, the TSA and ROA, were employed to enhance their performance. These optimizers mimic the collective behavior of biological systems, such as tunicates’ foraging patterns and jellyfish’s pulsating movements, to achieve optimal solutions within the model training process. Relevant features are extracted from patient data, potentially including demographics, medical history, lung function tests, and lifestyle factors. Among the metrics used to evaluate the performance of the optimized models are their accuracy and precision. The DTTS model’s excellent performance shows how well the DTC model predicts COPD. The greatest accuracy and precision scores of 0.907 and 0.911 support its COPD prediction accuracy. These findings demonstrate the DTTS model’s reliability and

  by Yogesh Prabhakar Pingle, Lakshmappa K. Ragha 
  Abstract: Music recommendation is considered as a solution, and the performance is degraded with prediction error. A novel approach for music recommendation based on facial emotions with the objective of extracting better feature information without loss is required. In this paper, an efficient cross-dense network model with multi-pooling is used to detect basic emotions from the face image. The complex cross-dense connections are provided for the extraction of most discriminate feature information. After recognising the emotion from the face, a new attention-based deep collaborative filtering recommendation system is proposed, with a list of Hindustani raga music to improve users moods. The proposed framework is invoked with the Facial Expression Recognition 2013 (FER-2013) dataset, and the recommendation is provided for happy and sad emotions from the ragas. The performance is compared with existing deep learning-based approaches. The proposed approach improves accuracy, precision and recall by 0.9972, 0.9896, and 0.9906.

• A novel method for solving probabilistic programming problem in interval type-2 fuzzy environment  
  by Babita Chaini, Narmada Ranarahu 
  Abstract: This paper introduces a novel mathematical model for stochastic programming in a type-2 fuzzy environment, addressing the dual uncertainties of fuzziness and randomness through fuzzy normal random variables. The proposed model innovatively converts fuzzy stochastic problems into deterministic ones using a two-step process: the -cut technique to remove fuzziness and the chance-constrained technique to handle randomness. This approach, involving perfectly normal interval type-2 triangular fuzzy numbers, is illustrated with a numerical example. The critical finding is the effective transformation of complex fuzzy stochastic problems into more manageable deterministic forms, enhancing computational efficiency and solution accuracy. The industrial implications are significant, offering a robust decision-making framework for sectors like manufacturing, logistics, and finance, where uncertainty is a critical factor. This methodology improves accuracy and reliability in operational and strategic planning, making it highly relevant for practical applications.

MIV-3 (modified inception V-3) is a model which enhances feature extraction and accuracy in diagnosis by combining an attention module and a squeeze-and-excitation (SE) module. Separable convolutions are utilised by MIV-3 model for increasing computational efficiency without impacting accuracy. A NPV and sensitivity of 98.37% and 94.68% respectively were depicted in the experimental data. Having a sensitivity of 94.68%, NVP of 98.85%, ROC-AUC of 99.14% and a specificity of 97.65% will help the model in predicting dental caries in a more accurate manner. The results indicate that the detection of periodontal disease happens at a faster pace and more accurately with the proposed AI-driven method. For developing the model, MATLAB program is utilised which offers a strong and dependable tool for diagnosis in clinical applications.

• Breast cancer classification refined using ResNet50 parameter tuning with lyre bird optimisation  
  by Sabura Banu Urundai Meeran 
  Abstract: Breast cancer remains a major cause of mortality among women, highlighting the need for accurate and efficient diagnostic methods. Deep learning, particularly CNNs, has improved medical image analysis, yet further optimisation is required for better precision and faster inference. This study optimises ResNet50 using the lyrebird optimisation (LBO) algorithm for hyperparameter tuning. A histopathological image dataset with cancer and non-cancer classes was used for training and evaluation. LBO fine-tuned key parameters such as learning rate, significantly enhancing model performance. The LBO-optimised ResNet50 outperformed standard ResNet50, Inception V3, and VGG16, achieving 98.85% accuracy along with high precision, recall, F1 score, and specificity (98.6%). The model also achieved an AUC-ROC of 99.98%, low log loss (0.0267), and reduced inference time (0.1377 seconds). Confusion matrix results showed fewer misclassifications. While promising for improving diagnostic reliability, additional clinical validation is recommended.
  Keywords: histopathological image analysis; deep learning models; hyperparameter tuning; diagnostic accuracy; medical image classification; confusion matrix analysis; performance optimisation; computer-aided diagnosis.

• Research on data-driven methods for evaluating and predicting the health status of energy storage cell packs  
  by Ning Li, Pengcheng Wei, Mingyang Wang, Yuan Liang, Dengyou Lei 
  Abstract: To address the limitations of traditional scheduling methods in modelling multi-variable coupling relationships and dynamic response delays, this paper proposes an attention mechanism-based multi-layer neural network (AMNN) optimisation framework. By employing a bidirectional long short-term memory (bi-LSTM) network, a multidimensional time-series prediction model incorporating electricity price fluctuations, battery aging, and meteorological features is constructed to achieve precise perception of the energy storage system's operational status. Validation using real-world operational data demonstrates that compared to the PSO optimisation algorithm, this method reduces scheduling errors by 19.7% during sudden load fluctuations and lowers the lifetime cost per kilowatt-hour by 12.3%.
