An effective Nuclear Model: from Nuclear Matter to Finite Nuclei

The momentum and density dependence of mean fields in symmetric and asymmetric nuclear matter are analysed using the simple density dependent finite range effective interaction containing a single Gaussian term alongwith the zero-range terms. Within the formalism developed, it is possible to reproduce the various diverging predictions on the momentum and density dependence of isovector part of the mean field in asymmetric matter. The finite nucleus calculation is formulated for the simple Gaussian interaction in the framework of quasilocal density functional theory. The prediction of energies and charge radii of the interaction for the spherical nuclei compares well with the results of other effective theories.Comment: 10 pages, 3 figures, 2 tables, To appear in the Proceedings of the 11th International Conference on Nucleus-Nucleus Collisions (NN2012), May 27-June 1, 2012, San Antonio, Texas, US

A packet forgery and packet drop attack detection using efficient Encoding and Decoding mechanisms.

A series of systems are connected to form a network. Vast amount of data moves through this network. A user who is not authorized to access the data tries to get forcible entry to the network by adding a malicious node or spoiling the node that already exists. The data in such network is not trustable. There is always a possibility that the information sent is changed or it is dropped in-between. Therefore identifying such behavior and the reason behind it is one of major issue. This is solved by using Provenance that verifies the data originality. The proposed technique is mainly concerned with the safe transmission of packet from sender to receiver through intermediate participants. The mechanism detects if there is any data change attack or data drop attack in the network and identifies the intruder responsible for such attacks with the help of provenance. The system is implemented experimentally and analyzed for its effectivenes
