Abstract: Concrete-filled steel tubular (CFST) sections are widely used in structural applications due to their superior mechanical properties, including high axial load capacity, energy dissipation, and fire resistance. This study presents a finite element analysis (FEA) of CFST columns under axial compression using ANSYS Workbench. The numerical model incorporates nonlinear material behavior, including an elastoplastic model with strain hardening for steel and the Drucker–Prager plasticity model for concrete to account for confinement effects. A structured finite element mesh was employed, with solid elements for concrete and shell elements for steel. The analysis considered realistic boundary conditions, applying displacement-controlled axial loading with fixed base constraints. The FEM results were validated against experimental data from the literature, showing a maximum deviation of less than 5% in peak axial load prediction. Load-displacement curves confirmed that steel confinement enhances concrete performance, delaying local buckling and increasing overall strength. Stress distribution analysis indicated effective load transfer between the steel tube and concrete core, while buckling patterns demonstrated progressive load redistribution, preventing sudden failure. These findings confirm that FEM is an effective tool for optimizing CFST designs and predicting their structural response under varying load conditions.

Abstract: The most popular method of forecasting SPs throughout the course of history was to make use of statistical models such as moving averages, ARIMA, and the GARCH. This was the most common strategy. It is difficult for these models to accurately predict future SPs due to the fact that financial markets are characterized by their complexity, non-linearity, and unending change. In spite of the fact that these models are able to effectively recognize particular linear trends within historical data, they often have a difficult time accurately predicting events that will occur in the future. As a result of the fact that price changes are impacted by a large variety of different factors, these models do not allow for the precise estimation of future SPs. These models are not particularly accurate as a consequence of this. In recent years, there has been an increase in interest in the topic of financial forecasting in relation to the capabilities of machine learning and deep learning approaches. This attention has brought about a number of interesting developments. The methodologies in question are able to accurately characterize not only the time-dependent patterns that are present in the data, but also the intricate and non-linear linkages that are there. In the field of time series prediction, recurrent neural networks (RNN) and long short-term memory (LSTM) networks, in addition to generalized recurrent units (GRU), have been shown to be successful tools. When it comes to capturing long-range dependencies in supply chains, it is preferable to traditional methods since it is more accurate.

Abstract: – Africa's abundant mineral resources present unprecedented opportunities for industrial transformation, yet the continent's industrial development remains constrained by inadequate energy infrastructure. This study examines the critical relationship between energy infrastructure development and mineral-based industrialization in Africa from a United States investment perspective. Drawing on recent empirical evidence and policy developments through 2025, we analyze how strategic energy investments can unlock Africa's mineral wealth while creating sustainable industrial value chains. Our analysis reveals that energy infrastructure serves as a fundamental catalyst for mineral-based industrialization, with renewable energy transitions offering particular promise for long-term sustainable development. The findings suggest that U.S. investments in Africa's energy infrastructure, particularly in renewable energy systems, can generate substantial returns while supporting the continent's industrial transformation. We recommend targeted investment strategies that leverage public-private partnerships and address key barriers including financing constraints, regulatory frameworks, and technical capacity limitations.

Abstract: The exponential growth of social media platforms has generated unprecedented volumes of user-generated content, creating vast repositories of public opinion and sentiment. This research investigates the application of sentiment analysis techniques to social media big data, examining methodologies for extracting, processing, and analyzing emotional insights from large-scale social media datasets. Through a comprehensive review of machine learning approaches, natural language processing techniques, and big data analytics frameworks, this study evaluates the effectiveness of various sentiment classification models when applied to Twitter, Facebook, and Instagram data. Our findings demonstrate that hybrid approaches combining lexicon-based methods with deep learning architectures achieve superior accuracy rates of 89.3% compared to traditional rule-based systems. The research also addresses critical challenges including data preprocessing, feature engineering, and scalability issues inherent in social media sentiment analysis. The implications of this work extend to business intelligence, political analysis, brand monitoring, and public health surveillance applications.

Abstract: The Internet of Things (IoT) based smart agriculture system is an emerging technology that uses sensors, gateways, cloud platforms, and mobile applications to provide real-time data on weather, soil moisture, crop growth, and livestock health to farmers. This research paper focuses on developing and implementing an IoT-based smart agriculture system. The system offers several benefits: increased efficiency, improved resource management, enhanced crop quality, better decision-making, and remote monitoring. However, potential negative impacts, such as cost, technical skills, dependence on technology, data privacy and security, and environmental impact, must be considered. Careful planning, implementation, and monitoring can help to mitigate these risks and ensure that smart agriculture systems are sustainable and effective. This research aims to give an overview of how predictive analysis and Internet of Things (IoT) devices, along with cloud management and security systems, can be used in agriculture to support multiple crops. It also takes into account the experiences of farmers and highlights the challenges and difficulties that may arise when introducing modern technology into traditional farming practices. By utilizing statistical and quantitative methods, this research seeks to bring about significant and positive changes in the current agriculture system. In simpler terms, this study explores how smart farming can enhance food production, resource management, and labor efficiency, while acknowledging the challenges and benefits of integrating modern technology into traditional farming practices.
