Abstract: This study examines the economic impact of Foreign Direct Investment (FDI) on Bangladesh's automobile sector, with particular emphasis on sectoral output, employment generation, and macroeconomic determinants of investment inflows. Using annual time-series data and sector-specific indicators, the analysis integrates descriptive statistics, correlation assessment, multiple regression modeling, and iterative epoch-based robustness evaluation to investigate both the contribution and sustainability of FDI-led industrial growth. The empirical results indicate that manufacturing-oriented FDI exerts a positive and statistically significant influence on automobile sector gross value added (GVA), supporting the hypothesis that foreign capital contributes to capital deepening, technology diffusion, and production expansion. Real GDP, serving as a proxy for market size, emerges as a strong determinant of FDI inflows, while human capital development and trade openness demonstrate complementary roles in enhancing investment attractiveness. However, the employment elasticity of FDI remains moderate, suggesting that capital-intensive investment patterns dominate labor absorption effects. Productivity growth, measured as output per worker, exhibits gradual improvement but reflects structural constraints related to limited local value-chain integration. The findings suggest that while FDI plays a constructive role in supporting sectoral expansion, its long-term developmental impact depends on institutional quality, skill upgrading, and domestic supplier ecosystem strengthening. Policy recommendations emphasize targeted human capital development, enhanced local content integration, regulatory efficiency, and export-oriented industrial clustering to maximize the transformative potential of manufacturing FDI within Bangladesh's automobile industry.

Abstract: The Iris Flower Classification problem is one of the most fundamental and widely studied benchmarks in supervised machine learning. It involves classifying iris flowers into three species (Setosa, Versicolor, and Virginica) based on four morphological features: sepal length, sepal width, petal length, and petal width. This review paper clearly defines the category of basic supervised machine learning tasks and explores the existing algorithms for classification. A novel comparative framework is proposed using Python and scikit-learn to evaluate five basic supervised algorithms—Logistic Regression, K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Decision Tree, and Naive Bayes—on the UCI Iris dataset. Performance is measured using accuracy, precision, recall, and F1-score. The study demonstrates that while all algorithms achieve high accuracy (>95%), KNN and SVM consistently outperform others in terms of perfect classification on the test set, highlighting their suitability for simple, linearly separable datasets. General Terms: Supervised Machine Learning, Classification, Comparative Analysis, Iris Dataset, Performance Metrics.

Abstract: The emergence of Large Language Models (LLMs) represents one of the most consequential shifts in the history of artificial intelligence (AI) and natural language processing (NLP). Built on the Transformer architecture with self-attention mechanisms, LLMs such as BERT, GPT-3, T5, LLaMA, and GPT-4 have achieved state-of-the-art performance across a broad spectrum of linguistic tasks, fundamentally reshaping how machines comprehend and generate human language. This survey presents a systematic and comprehensive review of the evolution of NLP—from rule-based and statistical methods to the current era of foundation models—examining key architectural innovations, pre-training objectives, fine-tuning strategies including parameter-efficient methods such as Low-Rank Adaptation (LoRA), and alignment techniques including Reinforcement Learning from Human Feedback (RLHF). We critically assess performance across standard benchmarks including GLUE, SuperGLUE, and MMLU, and analyze persistent challenges such as hallucination, bias, computational cost, and explainability. Furthermore, we explore the expanding landscape of LLM applications in healthcare, education, legal reasoning, and code generation, and outline promising future directions including multimodal models, efficient inference, and AI alignment. This work aims to serve as both an accessible introduction and a scholarly reference for researchers and practitioners engaged with the rapidly evolving frontier of AI-powered language understanding.

These techniques utilize medical image datasets, particularly dermoscopic images, to identify patterns and features associated with malignant and benign skin lesions. This review presents a comprehensive analysis of recent research on ML and DL-based approaches for automated skin cancer detection. Various algorithms such as Support Vector Machines (SVM), Random Forest, Convolutional Neural Networks (CNN), and transfer learning models are examined in terms of their methodologies, datasets, and performance metrics. Additionally, this study highlights the advantages, limitations, and challenges associated with these techniques. The review also discusses future research directions, including the development of more diverse datasets, interpretable models, and integration of AI-based systems into clinical practice to enhance diagnostic accuracy and healthcare efficiency.

Abstract: The development of the large language models (LLMs) has brought many new opportunities to automate the workflow involving complex computations. Nevertheless, current pipeline systems are still mostly fixed, needing to be configured manually and cannot adapt to dynamic settings. The paper suggests a new framework that is based on prompt-driven pipeline synthesis via context-aware auto-configuration of LLMs, which allows automatic synthesis and optimization of task-specific pipelines based on natural language input. The proposed approach involves a combination of timely engineering, contextually-based learning and sequence improvement to construct and adjust pipelines dynamically based on contextual information. An artificial performance model is used to determine the performance of the system relative to the current models that demonstrate that the accuracy, scalability and adaptability are improved without affecting the competitive latency. Such results demonstrate the utility of deploying LLMs as intelligent agents to optimally design pipelines as a scalable and adaptable solution to problems in the real world.

Abstract: Brain tumors are among the most critical neurological disorders and require early and accurate diagnosis to improve patient survival rates. Traditional methods of tumor detection rely heavily on manual analysis of medical images such as Magnetic Resonance Imaging (MRI), which can be time-consuming and prone to human error. This study presents a machine learning–based approach for the automated detection and classification of brain tumors from MRI images. The proposed system utilizes image preprocessing techniques to enhance image quality and remove noise, followed by feature extraction to identify significant patterns associated with tumor regions. Various machine learning algorithms, such as Support Vector Machines (SVM), Random Forest, and Convolutional Neural Networks (CNN), are applied to classify MRI images into tumor and non-tumor categories, and further categorize tumor types. The model is trained and evaluated on a labeled MRI dataset to ensure accuracy and reliability. Experimental results demonstrate that the proposed method improves diagnostic efficiency and achieves high classification accuracy compared to traditional approaches. This automated system can assist radiologists and healthcare professionals in early tumor detection, reducing diagnosis time and improving treatment planning.

For many researchers, one of the biggest concerns in academic publishing is the cost involved. Article Processing Charges (APC) in some journals can be quite high, making it difficult for students and early-career scholars to publish their work. However, there is good news that many journals offer free publication without any APC allowing researchers to share their work without financial pressure. Take a look on about free publication journals without APC.

Submit Your Paper  / Check Publication Charges

What Are Journals Without APC?

Journals without APC are platforms that do not charge authors any fees for submitting, reviewing, or publishing their research papers. These journals are often funded by universities, research institutions, academic societies, or government organizations. Their main goal is to promote knowledge sharing rather than generate profit.

In many cases, these journals follow a traditional publishing model where readers or institutions cover the cost through subscriptions. Some also follow a fully open model where both authors and readers can access content freely.

Why Choose Free Publication Journals?

Publishing in journals without APC offers several important benefits:

• No Financial Burden – Researchers can publish their work without worrying about high fees.
• Equal Opportunity – Students and independent researchers get a fair chance to contribute to academic literature.
• Focus on Quality – Selection is based on research merit rather than payment capability.
• Academic Growth – Helps beginners build their research profile and gain experience in publishing.

Points to Check Before Submission

While free journals are beneficial, it is important to ensure they are genuine and reliable. Keep these points in mind:

• Confirm that the journal follows a proper peer-review process
• ISSN and DOI approval as per the policies
• Check if it is indexed in recognized academic databases
• Read the submission and formatting guidelines carefully
• Avoid journals that promise very fast or guaranteed publication
• Being careful at this stage helps protect your research and academic reputation.

Sometimes researchers believe that free journals are of low quality. This is not true. In fact, several well-established journals do not charge any APC and maintain high academic standards. The key difference lies in their funding model, not in their quality.

Free publication journals without APC provide a valuable opportunity for researchers to publish their work without financial stress. With proper research and careful selection, you can find reliable platforms that match your field and maintain academic credibility. Focus on originality, follow the guidelines, and choose wisely, your research deserves to be shared without unnecessary costs.
