Abstract: The integration of blockchain technology and smart contracts represents a transformative advancement in auction systems, offering efficient, transparent, and secure decentralized platforms. This project leverages these technologies to facilitate a range of auction functionalities, from placing bids and managing the auction lifecycle to ensuring fair outcomes without reliance on intermediaries. By offering enhanced transparency and immutability of records, decentralized auctions built on blockchain have the potential to reduce administrative burdens, improve trust among participants, and ensure continuity of the auction process. However, challenges such as scalability, gas costs, and regulatory considerations necessitate robust design and compliance mechanisms. This paper explores the capabilities, benefits, and limitations of this decentralized auction system, emphasizing its potential to revolutionize auction processes while addressing critical gaps in traditional centralized models.

Abstract: This study explores the structural characteristics of selected deformed nuclei using theoretical frameworks, focusing on their shapes, energy levels, and quadrupole moments. Nuclear deformation results from the complex interplay between shell effects and the strong nuclear force, causing deviations from spherical symmetry. Advanced models, including the Nilsson model, Hartree-Fock-Bogoliubov (HFB) theory, and collective models, are employed to examine the influence of deformation on nuclear structure. The key findings emphasize the role of deformation in shaping rotational spectra and intrinsic quadrupole moments, with significant results for nuclei such as 152Sm, 238U, and 240Pu. Calculations of quadrupole deformation parameters and energy levels show strong agreement with experimental data, validating the theoretical approaches. The study also investigates the stabilization of heavy nuclei through deformation, which redistributes charge density and mitigates Coulomb repulsion. These findings have important applications in nuclear astrophysics, particularly in the rapid neutron capture process (r-process), as well as in nuclear technology, where insights into deformed nuclei contribute to isotope development and reactor design. A deeper understanding of deformed nuclei in this research advances both fundamental nuclear physics and practical applications

Abstract: Deformed nuclei, characterized by deviations from spherical symmetry, exhibit unique structural properties that are critical to understanding nuclear stability, reaction dynamics, and excitation phenomena. This theoretical study investigates the structural properties of selected deformed nuclei using advanced nuclear models and computational approaches. Employing Density Functional Theory (DFT) with Skyrme and Gogny interactions, alongside Hartree-Fock-Bogoliubov (HFB) calculations, the research analyses deformation effects on nuclear binding energy, charge distributions, and level densities. Transitional and neutron-rich nuclei are emphasized to explore the evolution of deformation, triaxiality, and nuclear softness. The results reveal significant impacts of deformation on nuclear moment of inertia and energy spectra, particularly in rare-earth and actinide regions. The inclusion of triaxiality further enhances the accuracy of predictions for level densities and excitation spectra. Comparisons with experimental data from gamma-ray spectroscopy and Coulomb excitation validate the robustness of the theoretical frameworks employed. This study addresses key gaps in understanding nuclear deformation, particularly for isotopic chains near the neutron drip line and transitional regions. The findings provide critical insights for refining existing nuclear models and guiding future experimental investigations. Furthermore, this research highlights the importance of incorporating pairing correlations and deformation effects to predict properties of nuclei far from stability. The study contributes to the broader understanding of nuclear structure and its applications in nuclear energy, astrophysics, and particle physics. These findings underscore the role of theoretical models in complementing experimental efforts and advancing nuclear physics research.

Abstract: Conventional keyword-based search systems lack contextual understanding and often return irrelevant or incomplete results. In enterprise environments, this becomes a bottleneck when users attempt to extract precise information from large and complex documents. This paper introduces AskMyDoc, a scalable project management tool and smart document querying system that leverages semantic search, large language models (LLMs), and vector databases. Unlike traditional SQL databases susceptible to human errors during updates, AskMyDoc processes and indexes documents using embedding techniques and retrieves answers using generative AI, thereby ensuring accuracy, speed, and consistency. The system is built with LangChain, FAISS, Sentence Transformers, and OpenAI's GPT models, supporting real-time natural language querying even across gigabyte-scale documents.
