layfair cipher is the well-known multiple letter encryption cipher. Here the digraphs in the plaintext are treated as single units and converted into corresponding cipher text digraphs. However because of the drawbacks inherent in the 5 X 5 Playfair cipher which adversely affects the security we proposed a 6 X 6 Playfair cipher and then coupled it with Linear Feedback Shift Register based Uniqu...

Mining is involved with knowing the unknown characteristics from the databases or gaining of Knowledge (Knowledge Discovery) from Databases to get more useful information from the database. Real time databases which are constantly changing with time, there may arise a point when traditional Data Mining techniques may not be adequate as there may be a previously unknown class label involved or n...

The Content Based Image Retrieval Technique is becoming more and more indispensable and vital. The paper proposes Content Based Image Retrieval technique incorporating WBCHIR (...

Patients with breast cancer that has metastasised to the meninges may now be treated with DepoCyt, a slow-release formulation of the cytotoxic drug, cytarabine. This treatment has been reported in studies published in October 2000( [1] ) and January 2001( [2] ). Both report encouraging therapeutic benefit in combating neoplastic meningitis in breast cancer, but cite arachnoiditis as one of the ...

Access control is a fundamental and essential mechanism to maintain security in ubiquitous computing (UbiComp). Flexibility is an important property for general access control system, which can be achieved by access or authority delegation. Existing delegation mechanisms are "subject-centered", thus in order to make sure that the unavailability of some users does not prevent the syste...
