The search of improved efficiency and performance in the constantly changing field of heat exchange technology continues to be a primary issue for many industrial sectors. The novel integration of shell and tube heat exchangers with trapezoidal baffles and nanofluids represents a major breakthrough in this endeavor. The goal of this seminar is to give a thorough grasp of the concepts, applications, and possible advantages of this cutting-edge technology through an in-depth investigation of it. For a long time, shell and tube heat exchangers have been essential in many different industries because they allow heat to be transferred between two fluids while keeping them apart. Their adaptable architecture allows for a wide range of applications. But the pursuit of more effective heat transmission and reduced energy use has resulted in the addition of trapezoidal baffles, which drastically affect the fluid dynamics inside the heat exchanger. Because they produce turbulence and improve heat transfer, trapezoidal baffles are a desirable option for applications where efficiency is crucial. Conversely, a new class of heat transfer fluids designed with nanoparticles are called nanofluids. These nanoparticles can be suspended in a base fluid; they are usually nanoscale particles. When applied to heat exchangers, nanofluids provide special thermal characteristics and the possibility of significantly enhancing heat transmission. When compared to conventional heat transfer fluids, nanofluids can provide better performance by increasing the thermal conductivity and convective heat transfer coefficients.

Maintaining sustainable railway tracks is crucial for our environment and economy. However, it comes with several tough problems and needs creative solutions. One challenge is the materials used in construction and upkeep. Traditional materials like concrete and steel harm the environment and wear out quickly. We can fix this by trying new materials like recycled plastics and sustainable timber, which are greener and longer-lasting. Another issue is the energy used and pollution created by trains. Most trains run on fossil fuels, which are bad for the environment. We're working on solutions like electric trains and other clean energy options to reduce emissions and noise. We also face problems with maintaining tracks. Current methods often disrupt travel, use lots of machinery, and create waste. To improve, we're developing technologies that predict when maintenance is needed, so we can fix issues before they cause big problems. Lastly, achieving sustainability in railway tracks needs teamwork and careful planning. We must consider how we use land, involve the community, and think about the environment in every step of the process. By using new materials, cleaner energy, advanced technologies, and involving everyone, we can make railway tracks more sustainable for the future.

Doing business is basically to the act of exchanging goods or services for money or other compensation. The process is simple, uncles it is overburden by different business rules, regulations, tricks and attractive practices to make a certain profit. From a businessman’s point of view she/he can do business on any product, available in this materialistic world with demand. In case of a product without demand also the demand can be created through proper marketing strategies. In the language of business world, product or service is important. When the businessman is dwelling in the academic domain, who will be his product? Is it the course she/he is offering? Is it the group of learners whom she/is going to place in the job market, as well as in the society? Will the business man look at her/his academic ventures just in the equation of profit and loss only? All these basic questions are inevitable in a critique’s mind and the same is searched in the life, work and ideologies of Shri Ghewarchandji Surana, the founder of Bengaluru based Surana Group of Institutions.

The identification of medicinal plants is essential for traditional medicine and botanical research, but it often requires specialized knowledge and considerable time. To address these challenges, this study utilizes advanced deep learning models to automate the classification of 40 distinct medicinal plant species. The research explores the performance of Convolutional Neural Networks (CNN), MobileNet, and a hybrid model combining MobileNet with Recurrent Neural Networks (RNN). These models are trained on a comprehensive set of plant images and evaluated for their effectiveness in classification tasks, with metrics including accuracy, precision, and recall. The CNN serves as a strong baseline for image classification, while MobileNet is employed for its computational efficiency, making it suitable for environments with limited resources. The hybrid MobileNet and RNN model is assessed for its potential to capture sequential and contextual patterns within the image data. The results of this study provide insights into the development of more efficient and accessible automated plant identification systems with practical applications for researchers, herbalists, and other practitioners. These advancements have the potential to enhance the speed, accuracy, and reliability of medicinal plant classification, supporting the growth of traditional medicine and botanical research

The increasing number of fake social media posts together with fraudulent content has become a major factor in online fraud growth which causes people to doubt trustworthiness and security. The authentication of post authenticity has evolved into a vital operation because user-generated content increases dynamically every day. The research investigates the effectiveness of XGBoost and Random Forest as well as Logistic Regression for classifying posts into real or fake categories. A total of 18,000 different online scam-related posts comprised the Employment Scam Aegean Dataset (EMSCAD). These algorithms show high success rates in detecting genuine content because they use their gained knowledge from previous data analysis. The study delivers important findings to automate scam detection systems which lead to better security measures and lower online fraudulent risks on different platforms.

Kidney diseases such as cysts, stones, and tumors are among the most prevalent health issues worldwide. Early and accurate diagnosis is critical to preventing severe complications, and computed tomography (CT) imaging plays a key role in this process. However, manual interpretation of CT scans is time-consuming and prone to subjectivity. To address this, we propose a hybrid deep learning model combining Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) units for the automated multiclass classification of kidney diseases using CT images. The CNN component extracts spatial features from the input scans, while the LSTM layers model spatial dependencies and enhance the learning of complex patterns. The model was trained and evaluated on a curated dataset consisting of four kidney conditions: Cyst, Normal, Stone, and Tumor. Extensive experimentation demonstrates that the proposed CNN- LSTM model achieves a classification accuracy of 99.6%, with precision, recall, and F1-score values exceeding 99% across all classes. Additionally, Gradient-weighted Class Activation Mapping (Grad-CAM) is employed for model interpretability, enabling visualization of discriminative regions in the images responsible for predictions. The results indicate the potential of the model to serve as a reliable decision-support tool for radiologists and clinicians. This framework paves the way for enhanced diagnostic accuracy and faster clinical workflows in nephrological imaging.
