    Randic, Seidel And Laplacian Energy Of NEPS Graphs
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2019) Yasir Ali; FA17-RMT-007; Dr. Sarfarz Ahmad; LHR TP 5645
    Let be the simple graph, then we can obtained the energy of a graph by taking the absolute sum of the eigenvalues of the adjacency matrix of . In this research we have computed different energy invariants of the Non-completed Extended P-Sum (NEPS) of graph . In particular we investigate the Randic, Seidel and Laplacian energies of the NEPS of path graph with any base . Here denotes number of vertices and denotes the number of copies of path graph . Our some of the results depend on the number of zeroes in base elements, for which we use the notation .

    Security Enhancement Analysis of NTDC
    (LHR TP 9333, 2024) Yasir Ali; FA20-RCS-005; Dr. Abid Sohail Bhutta; LHR TP 9333
    NTDC in Pakistan serves as the backbone of the country's electricity sector, with its primary purpose being the efficient and reliable transmission of electricity. NTDC not only ensures the seamless flow of electricity across long distances but also undertakes grid expansion and upgrades to accommodate growing electricity demand and integrate renewable energy sources. During the location stage, NTDC should persistently screen its organizations and frameworks for strange exercises, interruption endeavors, or indications of give and take. This incorporates constant danger location, log examination, and security occurrence checking. Early location is fundamental to answering arising dangers and limiting likely harm instantly. The purpose of current research is to implement the blockchain and get analyze the number of attacks on the under-discussed application, and analyze how secure the system is after the implementation of the Blockchain. In current research work we will analyze secure communication between back offices of the NTDC, and also analyze the number of attacks on the backend system. After complete review of existing system, blockchain base solution will be implemented for secure communication and data storage. Transactions will be stored on a distributed blockchain platform. This will provide a new digital identity built on blockchain for security and better performance. This concept ought to alleviate issues with application security in the government sector and lessen the likelihood of sensitive data being lost. After effective organization of the thought, examination will be recorded on client audits and check the quantity of assaults which will find success on blockchain. To evaluate the impact of implemented model on end user of NTDC a survey is conducted which conclude that the implemented model is way better than the older one on base of security, Assessability, sustainability, training, and perceived impact.
