An Information Technology System for Measuring Organizational Culture and Predicting Employee Turnover Based on Questionnaire Data and Text Mining
Abstract: This paper implements the prediction of employees leaving their company using conventional methods such as surveys and modern techniques like mining textual data. The open-ended responses were analyzed (12,847 words of text in total) resulting in a vocabulary of 1,892 unique words. The words that came up most often in positive reference were “team” (142), “growth” (98) and “resilience” (87); negative terms found included “pressure”, which occurred 156 times, along with injustice (112) and burnout (76). The average sentiment score was 2.8/5, with 34% of responses very negative and only 18% very positive. Various machine learning models have been tested to predict for turnover. If we only use closed-ended questions, though, XGBoost reaches an accuracy score of 78%. But then features for text mining (sentiment scores + keywords) increased accuracy to 87% (+9%), precision:0.85, recall:0.84, AUC-ROC 0.89 Key risk indicators based on text mining included the term “unfair” (turnover risk 4.2x higher), “burnout” (3.8x higher risk) while “recognition” (3.5x lower risk) and growth (2.8 times lower risk). The turnover risk increased by 31% per 1-point decrease in sentiment score. The hybrid XGBoost model with text features performed better than fine-tuned BERT ( accuracy of 84% ). This proposed IT stains enables organization to proactively identify risk oriented employees through linguistic signals in the open-ended feedback allowing timely intervention by HR wherein it improves efficiency.

Expert Systems Using Fuzzy Logic for the Early Alzheimer’s Disease Diagnosis
Alzheimer’s disease continues to be an important international health concern and early, accurate diagnosis is essential for treatment initiation and management of the disease. However, early identification of Alzheimer ’s disease (AD) remains a formidable challenge, mainly attributed to the complex underlying pathology and clinical heterogeneity along with conventional neuroimaging and cognitive tests possessing limited accuracy when applied individually. In this work, we aim to improve the sensitivity and specificity of detection for early-stage AD by developing a hybrid method based on MRI neuroimaging features woven with data from cognitive assessments through using a fuzzy-based expert system combined with machine-learning techniques. Cognitive data were collected from 60 subjects using a structured questionnaire covering multiple cognitive domains and MR-derived structural features, representative of neurodegeneration patterns. In particular, a fuzzy inference system was used to model the uncertainty and to represent nonlinear relationships frequently seen in medical data, then its output data were analyzed by a supervised classifier. Various cross-validation methods were used to validate the performance of the proposed model and an overall accuracy 91.9%, predictive accuracy 92.5%, sensitivity 91.1%F1-score ~91.5% and Area Under the Curve (AUC) AUC = 0.94 with our results defined a high discriminative effect size large to very large supported by Lakehead Bayesian Test. In addition, prodigious find the pressure of statistical significance testing and confidence interval checking implied composites that were references to fortune. . In conclusion, our results indicate that the development of fuzzy expert-based hybrid models merging neuroimaging and cognitive data has great potential for state-of-the-art early accurate classification of individuals with Alzheimer’s disease, thus providing a new promising reliable screening tool useful for clinical decision-making.

Innovative New Framework of Complex Q-Fuzzy Set and Its Application
The Q-fuzzy set (Q-FS) is a powerful general formal framework that generalises the notion of a fuzzy set (FS) when the domain of the FS extends from the universal set X to the product between X and Q. This article presents a novel complex Q-fuzzy set (CQ-FS) notion by extending the range of Q-fuzzy set (Q-FS) values to the unit circle in the complex plane by adding a further term called the phase term. This action characterises CQ-FS’s elements in terms of time. Based on these mathematical tools, we present the practical possibilities for basic operations on this concept, such as intersection, union, and complement, supported by numerical representations with some mathematical properties. Finally, we present a scenario for a decision-making problem in the medical field where our concept plays a dynamic role in representing the problem data, with time being a significant factor in determining symptom severity. To address this problem, we have developed a multi-step mathematical algorithm that helps the user create a simulation system for handling such issues within a decision-making environment.

A recent study of the Darbaugh problem's stability in partial differential equations using fixed-point theory
The stability analysis of solutions to nonlinear PDEs involves a fundamental and serious problem in applied mathematics and physics. The paper aims for the first time ever to provide a stability analysis for a class of nonlinear initial-boundary value problems called Darbaugh problems. To achieve this goal, we convert the PDE into a fixed-point equation via a nonlinear solution operator so that we can investigate several kinds of stability interested in Hyers-Ulam and Lagrange stability using the fixed-point theories of Banach Contraction Principle, Krasnoselskii’s Theorem and Schaefer’s Theorem, by using a variety of suitable function spaces, especially Banach algebras such as C(X), and Sobolev spaces to make use of their topological and multiplicative properties. New stability theorems are proved. One of them states that if the nonlinearity satisfies a Lipschitz-type condition where the constant can be taken sufficiently small relative to the norm of the linear solution operator then the problem has uniform Hyers-Ulam stability. Another one states that if the operator is decomposable into contractive and compact parts then we get Lagrange stability. Finally, uniform a priori bound gives bounded-input-bounded-output stability. In conclusion, the fixed-point method gives rise to explicit conditions for stability that can be verified algebraically. This provides a unified and robust alternative to the classical energy methods and adds analytical techniques to our toolbox of methods for the analysis of nonlinear PDEs.

Design of Reliable Queue Systems in Complicated Logistics Networks by Using Mathematical Programming Methods
How to construct strong queuing schemes in a network logistics setting using mathematical programming will be considered in this paper. As global supply chains get increasingly complex, Effective management of queues at logistics hubs is crucial for business performance. This work provides a unifying structure which combines queueing models and mathematical programming methods to minimize waiting time, maximize capacity utilization, and optimizing the allocation of resources (e.g., servers) in an unknown demand environment. We employ both analytical models (e.g. M/M/c queueing systems) and simulation techniques developed by means of WinQSP software to explore performance measures under varying circumstances. For illustration, sortation systems of a realistic distribution center network have been placed in simulated. The computational results also show that our technology can reduce the average waiting time by 42% and increase the system's utilization rate by 28% compared to traditional methods by applying mathematical programming for optimal server scaling. The findings of the study will enable logistics managers to develop stable queuing systems that are responsive to demand fluctuation and service performance. This study bridges the gap between queuing theory and practical logistics applications, providing managers with actionable insights.

A Graph-Aware Recurrent Fusion Deep Ensemble Architecture for Fake News Detection
With the rapid spread of fake news on social media platforms, it has become essential to develop effective detection mechanisms that overcome the limitations of content-only or propagation-only approaches. This study aims to design a unified framework that jointly models textual semantics and diffusion characteristics for improved misinformation detection. To achieve this, we propose GRAFT-FND, a Graph-Aware Recurrent Fusion Deep Ensemble architecture that integrates contextual word embeddings (Word2Vec, BERT, and BERTweet) with recurrent neural networks (RNN/GRU/LSTM/BiLSTM) and graph-based node embedding methods (Node2Vec and DeepWalk) within a fusion-aware learning module. Extensive experiments conducted on the Twitter15 and Twitter16 benchmark datasets using 10-fold cross-validation demonstrate that the proposed framework consistently outperforms baseline and recent state-of-the-art models, with the fusion mechanism and propagation-aware representations contributing significantly to performance improvement. The results indicate that jointly modelling semantic and structural information enhances the ability to capture complex misinformation patterns and improves generalisation across datasets. In conclusion, the proposed framework provides a robust and scalable solution for fake news detection in social media environments. Future work is recommended to investigate adversarial robustness, real-time deployment, and the integration of multimodal data sources.

Educational Data Mining for Predicting Academic Attrition in Iraqi Universities: A Hybrid KDD-Based Approach using Weighted Euclidean Distance and Neural Architectures
Academic attrition within the higher education sector of Iraq is accepted as a notable phenomenon with substantial socio-economic impacts. Within the digital revolution environment of the higher education sector of Iraq, there is a growing need to exploit the student data repositories as a strategic tool. The objective and purpose of this research is to enhance the existing strong framework, based on the Knowledge Discovery in Databases (KDD) process, whereby the risk factors associated with academic attrition can be proactively identified. Through the use of advanced image mining techniques, such as a texture-like matrix, along with a precise prediction model utilizing a Weighted Euclidean Distance with parameters relevant to education, a precise prediction model is now attainable. A comprehensive evaluation of different architectures for machine learning was carried out using a rich dataset of 5,000 students, designed based on the Iraqi context for the educational system. The results show the benefits of using Artificial Neural Network (ANN) methodology with Knowledge Discovery in Databases (KDD) methods, resulting in an accuracy rate of 94.21%. The research provides a strategic framework for Iraqi university administrators seeking to improve student retention using early warning systems

Experimental Evaluation of Attention-Based Explainable AI Models for Detecting Zero-Day Threats in (IoT) Systems
The paper proposes to evaluate attention-based explainable artificial intelligence (XAI) models for their potential to detect zero-day attacks on Internet of Things (IoT) networks. The evaluation will be done by comparing the performance of attention-based XAI models with other baseline models and post-hoc XAI models, considering their trustworthiness as well as their performance. We use a suite of publicly accessible and proprietary IoT intrusion datasets that vary in terms of the underlying protocol, devices, and intrusion types used in the attack scenarios. The study compares attention-based deep models, including sequence- and graph-oriented models, against non-attention-based neural and tree models as baselines. Evaluation criteria are detection performance, faithfulness and stability of the explanations, robustness to domain shift, noise, and adversarial attacks, as well as computational efficiency relevant to edge computing scenarios. In all scenarios, attention-based models achieve superior zero-day detection rates and overall F1-scores compared to the non-attention models, while maintaining competitive latency and resource utilization for edge devices. Explainability of the attention-derived explanations has been shown to be more faithful and stable compared to the post-hoc XAI methods, and they also have better graceful degradation characteristics when faced with domain shifts and adversarial attacks. Attention-based Explainable Intrusion Detection System (IDS) models have promising characteristics of high accuracy, robustness, and interpretability for zero-day threat detection in IoT environments.

The combined method for solve the constraint optimization problems uses the augmented Lagrangian and line search technique
This paper presents an effective hybrid optimization methodology that combines the Augmented Lagrangian (AL) framework with the Limited-memory Broyden–Fletcher–Goldfarb–Shanno (L-BFGS) algorithm to address large-scale constrained problems. The method leverages the AL framework to impose quadratic and linear penalties on the constraints, transforming the constrained problem into a sequence of unconstrained subproblems, driven by the computational asymmetry of decomposition. Then, the L-BFGS method is used to make these smaller problems easier to solve. L-BFGS efficiently approximates the search direction with just operations per iteration by using a two-loop recursion with a limited history of gradient pairs. This avoids the problem of calculating the Hessian matrix. It is therefore very important for large-scale situations. The AL-BFGS design that comes out of this speeds up convergence in the inner minimization loop. The outer loop, on the other hand, keeps updating the Lagrange multipliers and changing the penalty parameter based on the primal and dual residuals. by making an efficient iterative solution and handling the inequality constraints correctly.

Hybrid Framework for Multi-Disease Chest X-Ray Diagnosis Using Vision Transformers with Label Noise Correction and Uncertainty Calibration
The most accessible radiological technique for thoracic disease detection and diagnosis uses chest X-ray imaging as its primary method. The deployment of automated chest X ray analysis systems faces two main obstacles because of untrustworthy labels in large datasets and unpredictable predictive confidence levels. The research proposes a hybrid system which combines Vision Transformer (ViT) architecture with methods to handle noisy labels and produce accurate probability estimates for multiple disease diagnosis in chest X-ray images. The system trains on CheXpert and NIH ChestX-ray14 datasets while using Co-Teaching and DivideMix noise-handling methods and self-supervised pretraining to enhance feature resistance against supervision errors. The framework uses temperature scaling and Monte Carlo dropout as post-hoc methods to enhance confidence reliability without compromising discriminative performance. The system aims to reach performance levels that match or exceed traditional CNN and standard ViT models in AUROC and mAP and F1 score metrics. The system reduces the effects of untrustworthy labels while generating meaningful confidence scores which doctors can understand. The model produces Grad-CAM++ explanations to assist doctors in understanding its decision-making process. The hybrid system works to develop AI systems which deliver both exact results and safe operational readiness for real-world chest X-ray decision support systems.

Fairness-Aware Mutual Information for Feature Selection in Employee Attrition Prediction
Feature selection is a critical part of creating machine learning models, particularly for touchy areas such as HR, finance, and healthcare. The literature shows that many current methods only review the results based on accuracy while ignoring both fairness and interpretability. This study presents a feature selection method which fuses Mutual Information for assessing feature relevance, while imposing fairness constraints by measuring the Equal Opportunity Difference (EOD) metric. The aim, of this study, is to maximize accuracy, fairness, and interpretability. The methodology was tested on the IBM HR Analytics dataset for six models (Fair Logistic Regression, Explainable Boosting Machines (EBMs), XGBoost, Random Forest, SVM and KNN). Fair Logistic Regression, provided the best overall results with 96% accuracy and little fairness bias (EOD = 0.005). XGBoost and Random Forest had good predictive reliability, evidence of disparity in fairness measures. Moreover, Explainable Boosting Machines (EBMs) met accuracy standards, and have good interpretability, so these models could be used in intervention areas where transparency of the model/construction process is required.

Real-Time Emotion Recognition in Human-Robot Interaction Using Deep AI Models
Emotion recognition in human-robot interaction (HRI) is important in order to develop socially aware and responsive robotic systems. In this work, a near real-time emotion recognition architecture is introduced which combines deep AI models such as CNN, and recurrent architectures (LSTM/ GRU) for audio and visual-based emotion detection. The system is tested on the benchmark datasets like FER-2013 and RAVDESS. The goal is to provide a strong and scalable approach that can serve as a step toward the full integration of emotionally intelligent robots into everyday life, to encourage empathic, adaptive, and rewarding human-robot interaction. The proposed deep AI model was tested on a dataset comprising 5,000 multimodal samples of human emotional expressions collected in controlled and real-world human-robot interaction scenarios. The dataset included five emotional categories: Happy, Sad, Angry, Neutral, and Surprise. Experimental results show the effectiveness of the proposed system based on the public datasets, and its practical use in the simulated human-robot interaction (HRI) scenario. Also, the proposed approach provides high accuracy and low inference delay, which can support robotic agents to have effective emotion-adaptive behaviors in live-interaction environments.

Stable Numerical Solution of an Elliptic PDE Inverse Problem Subject to Incomplete Boundary Conditions
This paper addresses the inverse problem of reconstructing complete steady-state solutions for elliptic partial differential equations when boundary information is incomplete a situation common in electromagnetic, thermal, and geophysical modeling where full Dirichlet or Neumann data are not available. The objective is to develop a numerically stable and reproducible method that reconstructs the interior field and missing boundary trace from partial boundary measurements contaminated by noise. To that end, the inverse task is posed as a Tikhonov-regularized optimization problem in which the unknown Dirichlet trace on the unobserved boundary segment minimizes a least-squares discrepancy between forward-model predictions and boundary observations; the forward PDE is discretized by the finite element method and the gradient of the discrete cost is computed via the adjoint-state method, enabling efficient computation independent of the number of boundary parameters. The optimization uses a nonlinear conjugate-gradient scheme with automated L-curve-based regularization selection. Numerical validation on synthetic test cases including a unit-square Poisson problem and a circular-domain example shows that the proposed approach recovers the interior field and the missing boundary trace with low RMSE and small relative L^2 errors for noise levels up to 5%, whereas unregularized reconstructions suffer severe noise amplification. These results demonstrate that the FEM + adjoint + H¹-Tikhonov methodology provides a practical and stable solution approach for elliptic inverse problems with partial boundary conditions, and that this approach scales to moderate resolution meshes and is potentially extendable for non-smooth targets, nonlinear PDEs, and realistic measurement models.

Multitype Convolutional Networks for Improved Iris Classification
Iris recognition is an essential biometric modality that has achieved far-reaching adoption in most applications including government ID plans, voter registration and de-duplication, international border crossing, and mobile device authentication. Due to its high sensitivity as a secure, non-invasive human identification technique, iris recognition has various challenges like light variation, specular highlights, motion blur, and image noise to deal with. To overcome these limitations, deep learning models have been employed more widely both for pattern matching and feature extraction so that higher quality and robust detection of complex and highly unique iris textures can be achieved. The current paper presents a successful two-stage iris recognition system. Iris segmentation and detection are achieved in the first stage by using the HoughCircles algorithm and inpainting improved to achieve higher image quality and remove artifacts. The second stage employs a new deep network employing multiple types of convolutional layers like regular, spatial, and depthwise convolutions to execute efficient feature extraction and accurate classification. The proposed model was also validated and tested with the MULBv1 iris image database and achieved promising results with the classification accuracy of 98.21% and F1-score of 98.16%. The results prove the effectiveness of the proposed method as a feasible and practical solution to be used in real-life iris identification systems.

Enhancing IoT Network Security Through Deep Learning-Based Intrusion Detection
The internet of today is a mainstream aspect of life, with increasingly more devices in the Internet of Things (IoT) ecosystem becoming networked. Although they are leaders in the market today, IoT networks are beset by increasingly more degrading security problems that confuse neatly defined solutions. These weaknesses need to be halted because new threats continue to challenge the resilience of IoT networks. Although the existing methodologies are made to provide more security, there remains untapped potential in machine learning development. Certain of the machine learning and deep learning methods, and benchmark data sets, used for IoT security enhancement are described in this paper. It proposes a new deep learning-based Legitimate Load Testing (LLT) attack detection algorithm implemented in Python and supported by libraries such as TensorFlow, scikit-learn, and Seaborn. Experimental outcomes confirm that the deep learning model improves attack detection precision significantly, which results in more effective countermeasures for protecting IoT networks.

Blockchain Scalability Analysis and Improvement of Bitcoin Network through Enhanced Transaction Adjournment Techniques
Bitcoin is the most popular among the cryptocurrency it includes Litecoin, Dogecoin, and Peercoin. Blockchain is the foundation of cryptocurrencies, most cryptocurrency technologies are decentralized. Despite its benefits, blockchain remains a cutting-edge technology with flaws that can be addressed to increase efficiency. Therefore, this research digs into the topic of scalability in blockchains and presents a comparative analysis of numerous blockchain metrics with real time data. We performed this using a blockchain simulation (BlockSim), and then looked at effective techniques that may be utilized to overcome the limitation by comparing the simulator and real-world circumstances. The second part of this research work proposes an effective algorithm that improves scalability of Bitcoin network through efficient transaction deferment. In this study, we propose an algorithm that improves the current Bitcoin protocols using Inventory messaging (INV) and transaction deferment or adjournment. The deferred transaction relay on the message to carry multiple raw transactions. These improvements are compatible with the existing Bitcoin Network protocols. The improve algorithm was simulated using BlockSim and AnyLogic Multi Paradigm Simulation Engine, the simulators ware configured with 1000 nodes interconnected in a Bitcoin Like Peer-to-Peer network. The result of the simulation shows that the adjourned transaction protocol provides for a controlled reduction in the number of messages required to propagate a transaction at the cost of a modest increase in transaction propagation time. We may manage the tradeoff between the quantity of messages and propagation latency by adjusting the threshold and timeout values, thereby improving the network's overall scalability.

Categorization of Celebrity Photos Based on Deep Machine Learning for Feature Extraction and Classification
In feature extraction, images or videos are analyzed to identify facial features before pinpointing the exact target. Significant progress has been made in the realm of feature extraction through deep learning. With deep learning technologies, developers have created algorithms for facial analysis and recognition that enhance accuracy and effectiveness. Consequently, programmers and developers have started to implement facial recognition technology in a wide range of applications to address these challenges. The identification process is particularly difficult due to the abundance of unstructured datasets. In real-world scenarios, identification continues to be quite challenging despite various methods proposed so far. This paper aims to analyze celebrity categorization based on deep features under different conditions. Most algorithms are influenced by these problematic factors, whether intentionally or unintentionally. Six datasets are utilized in this paper: the Open Famous People Dataset, Celeb Identification Dataset, Bollywood Celebrity Localized Dataset (170), Football Player's Dataset, Mini_LFW, and Nepali Celeb Localized Dataset. Most of these images feature celebrities including actors, singers, players, actresses, politicians, and social figures from diverse nationalities and countries. Therefore, this paper offers a combination of results from classification methods: Multilayer Perceptron Classifier (MLP), Decision Tree Classifier (DT), Bootstrap Aggregation Decision Tree Classifier (TreeBagger), Extreme Gradient Boosting Classifier (XGB), and Stochastic Gradient Descent Classification (SGD), alongside deep learning methods for feature extraction (VGGFace2 model pretraining and SENet-50 model architecture) across six different facial datasets. The results demonstrated that the highest accuracy (F-measure, Recall, and Precision) was achieved following the training and testing process in all datasets using the MLP and SGD classifiers.

Feature Fusion for Improved Skin Cancer Diagnosis Using Support Vector Machines
the early detection and successful treatment of skin cancers, a potent form of cancer, calls for the use of sophisticated diagnostic instruments. This study delves into the use of support vector machines (SVMs), to cope with the inconsistencies occurring among skin lesions, by merging them with feature fusion techniques. SVMs are preferred for this situation, as they are highly effective when it comes to the management of exceedingly dimensional data. Initially, in order to train and enhance the diagnostic capacity of the SVM classifier, a single and all-inclusive single dataset was generated through the analysis, identification and extraction of a wide variety of explanatory features (including colour, texture and shape) from a dataset comprising 10000 dermatoscope skin lesion representations. This was followed by the use of early and late fusion approaches, to generate an extensive dataset of descriptions, for assessing the reliability of the SVM classifier. Finally, the accuracy, precision and recall of the SVM classifier were ascertained by way of an objective dataset, comprising 25 dermatoscope representations of malignant and benign lesions. The accuracy, precision and recall of the SVM classifier are supported by its capacity to distinguish 10 true positives, 12 true negatives, three false positives and zero false negatives. As such, the SVM classifier can be considered effective, for the early detection of skin cancers. The results from this investigation verify that the capacity of SVMs, in terms of skin cancer diagnosis, is greatly improved with the utilization of feature fusion techniques. Also verified through this undertaking, is the effectiveness of innovative computational procedures, for the delivery of dependable medical diagnoses.

Model-Driven Engineering for Adaptive Software Systems in Dynamic Environments
In such an environment, an urgent requirement has been felt for systems that can adapt at runtime to changing situations, as available computing environments are more and more dynamic and complex. The research presented in this paper is about the use of Model Driven Engineering (MDE) for systematic support of managing software adaptability. MDE advocates the use of models as core working entities in software development, allowing you to raise the level of abstraction, transformation and consistency of the adaptive processes. The work presents a full-fledged framework that combines MDE principles together with real-time monitoring, self-configuration strategies, and the MAPE-K feedback loop. By means of theoretical study and cross-domain case comparisons (smart environment, education, transportation, and cloud computing), we show how MDE enables the structural, behavior, and parameter adaptation. The quality of adaptation is evaluated based on a series of metrics, including adaptivity time, model similarity, and transformation delay. The results substantiate the distinctive capability of MDE-based approaches for responsiveness and system correctness in volatile environments and draw attention to important limitations with respect to tool maturity, run-time sync service and scale. The paper concludes by discussing potential future endeavors to drive the field forward, including runtime metamodel evolution, AI-driven model adaptation, and decentralized model-driven infrastructures. The work casts MDE as a suitable and generalizable basis for the development of adaptive systems that exhibit resilience to unanticipated failures, context-awareness, and autonomous adaptation.
Brain age prediction from MRI images based on a convolutional neural network with MRMR feature selection layer
An sophisticated medical technique used to diagnose illnesses and brain disorders including multiple sclerosis, Alzheimer's, and other neurological ailments is the ability to predict the biological age of the brain using MRI pictures. To do this, sophisticated algorithms and neural networks are used to scan MRI brain pictures in order to extract different brain properties, including cortical thickness and volume. The brain ages of individuals are determined by matching their characteristics against MRI imaging data collected from other patients. The research employs a new deep learning model named CNN-MRMR which combines features from the Minimum Redundancy Maximum Relevance (MRMR) feature selection approach and Convolutional Neural Network (CNN) technology. MRI images of human brains are initially processed by the convolutional network to extract age-related characteristics. The feature selection layer uses MRMR algorithm which identifies essential characteristics for a target variable while minimizing feature redundancy to select the optimal feature subset. The system employs a regression layer as the final stage to predict brain age by utilizing the selected characteristics. The proposed method for estimating individual brain age attained a prediction accuracy of 90.3%, outperforming results from comparable research studies.

Generalized (theta, theta)- Semi-derivations of Prime Near-rings
The concept of differential algebra has been initiated before many years ago. This research topic has inspired a lot of authors to its study with different algebraic structures such as rings or semi-rings. Their studies provided many good results in this field some of which by extending from previous works and others by introducing new notion in this direction. In this article a type of rings are called prime near-rings have been considered. In particular, we introduced the idea of generalized (theta,theta)-semi-derivation of prime near-rings and studied the commutativity of such types of rings by using this notion.
