Abstract: This research proposes a decentralized courier tracking system using blockchain technol- ogy and smart contracts, aimed at enhancing transparency, trust, and security in logistics. The solution is implemented on the Volta blockchain and integrates MetaMask[3] to facilitate se- cure interactions between participants without relying on centralized intermediaries. The sys- tem automates shipment updates, maintains immutable tracking records, and protects sensitive data through cryptographic mechanisms. The implementation demonstrates improved trace- ability, operational efficiency, and stakeholder accountability. Performance evaluation indi- cates significant enhancements in security, cost-effectiveness, and scalability when compared to conventional courier tracking methods. The proposed system offers a robust alternative for modern supply chain management[6].

Abstract: This study examines the use of GradientBoostingRegressor, StackingRegressor, and Gradient Boosting Regression with HistGradientBoosting in developing models that predict the compressive strength (fcu) and splitting tensile strength (fsp) of steel fiber-reinforced recycled aggregate concrete (SFR-RAC). The information comprises 465 compressive strength and 339 splitting tensile strength data of concrete mixes with varied ratios. Training and model testing were performed using 80/20 split with PSO for the hyperparameter optimization. The performance of the model was measured with four statistical metrics: coefficient of determination (R²), mean absolute error (MAE), root mean squared error (RMSE), and mean absolute percentage error (MAPE). Out of the models, Gradient Boosting Regression with HistGradientBoosting performed better in terms of prediction, with StackingRegressor taking the second rank. SHapley Additive exPlanations (SHAP) and feature importance were employed to determine the influence of input parameters on model predictions. From the results obtained, it was evident that the water content, cement content, and fiber ratio influence considerably the strength of SFR-RAC. The models give good insights regarding SFR-RAC mixture behavior, which is helpful in the production of environmentally friendly concrete with greater enhanced strength. Future research can enhance the data and use other predictor variables to further support these models.

Abstract: To meet the need of productivity concerns, project timelines, and changing needs, this research explores the interesting realm of web service development. The overall purpose of this research is to develop an easy-to-use and effective development system based on the Django framework. This provides programmers with the facility to simply develop web services that are efficient, effective, and reliable. Utilizing the Model-View-Template (MVT) design pattern is important, as it is compatible with list management systems. The overall effectiveness and efficiency of the system are improved by web page creation being automated using HTML, CSS, and Python modules; protocols for data sharing are standardized, system users are decentralized, and user login and registration processes are accelerated are all prioritized at their best. My SQL maintains the data base efficiently, and Django manages the smooth data interaction to provide an integrated and efficient user experience. Another central area of focus in this research is the development of a web application that provides secure, real-time user interactions while encrypting data to preserve its confidentiality and integrity. Django REST framework is employed to create a stable service that integrates with the front-end seamlessly through REST APIs. This allows HTML/CSS and JavaScript to drive a dynamic and interactive user interface. The research points out the key features of Django, including its administrative capabilities, Object-Relational Mapping (ORM), comprehensive documentation, secure and rapid development features, and REST API support. A deeper understanding of this dynamic subject attempts to shed light on the development, importance, challenges, and modern solutions in web technology and web service development. Following our research, the goal is to use Django to develop are liable, effective, and secure online application. Our goal is to use all of its characteristics to streamline the development process. Django's solid frame work promises the assurance of scalability and reliability .Our aim is to utilize its benefits for an extensive, modern, and efficient web service creation, ensuring a successful outcome meeting the increasing demands for efficient web services. In today’s digital world, websites and web applications play a very important role in how we communicate, do business, and share information. To build these websites, developers use tools called web frameworks. One of the most popular frameworks is Django, which is written in the Python programming language. This research paper explains how Django helps developers create websites faster and more efficiently. Django follows a structure called MVC (Model-View-Controller), or in Django’s case, MTV (Model-Template-View). This helps keep the code organized and easy to manage. Django also comes with many built-in features like user authentication, database management, security, and admin interface, which save time and effort for developers. The paper highlights Django’s advantages like its security features, scalability, and reusability of code. It also compares Django with other popular frameworks to show where Django performs better and where it might not be the best choice. In short, Django is a powerful tool that allows both beginners and professional developers to build high-quality web applications quickly and securely. This research explores Django’s role in modern web development and why it is a preferred choice for many developers and companies .The research by Idris et al. emphasizes Django's comprehensive nature, highlighting its suitability for developers seeking a full-featured framework that handles various aspects of web development out-of-the-box. This contrasts with frameworks like Flask, which offer more flexibility but require additional setup for features that Django provides by default. Moreover, Django's emphasis on security is notable. It includes protections against common web vulnerabilities like cross-site scripting (XSS), cross-site request forgery (CSRF), and SQL injection, ensuring that applications built with Django are robust and secure.
