As the popularity of digital cameras increases, some limitations of digital technology are becoming apparent and on the other hand it has become imperative to ensure security of information. Looking ahead towards the authentication scheme with a view to optimize it. Skin detection [1] is a very popular and useful technique for detecting and tracking human-body parts. It receives much attention ...

Whenever object-oriented applications that use the Enterprise JavaBeans (EJB) environment have to store data in a database, there is a need to combine EJBs with access to persistent data. The current use of entity beans for persistent data storage has a number of weaknesses. Component level inheritance and dynamic querying are not supported appropriately, and the whole approach seems to be over...

1 Objektorientiert: Die große Hoffnung Anfang der 70-er Jahre wurde der Begriff der Softwarekrise für den Bereich der EDV geprägt, um die großen Probleme der Softwareerstellung zu verdeutlichen. Diese bezogen sich sowohl auf die frühen Analyseund Definitionsphasen als auch auf die häufig über 70% der Gesamtkosten ausmachende Softwarewartung. Kritikpunkte waren vor allen Dingen fehlende Technike...

In this work, the reconstruction of the Burt’s table, Greenacre (1988)’s Joint Correspondence Analysis (JCA), and Gower & Hand (1996)’s Extended Matching Coefficient (EMC) are compared to Multiple Correspondence Analysis (MCA) in order to check the quality of the methods. In particular, for the whole table, the ability is considered separately the diagonal, and the off-diagonal tables, that is ...

We present a pseudo random bit generator whose security is based on the intractability of the discrete logarithm problem in the group E(Fp) of rational points on an elliptic curve over a finite prime field Fp. The bit generator is implemented within the framework of the Java Cryptography Architecture (JCA). It uses an elliptic curve E chosen such that both E(Fp) and its twist E (Fp) are of prim...

D-penicillamine (D-pen) has gained wide-spread use as a potent suppressor of disease activity in rheumatoid arthritis (RA) and juvenile chronic arthritis (JCA). The drug has been established for antirheumatotd therapy on the basis o f a considerable number o f comparative clinical studies o f D-pen treatment versus placebo or other disease modifying antirheumatic drugs (DMARDs). Despite the pos...

BACKGROUND To raise awareness about the accessory and cavitated uterine masses (ACUM) with functional endometrium as a different entity from adult adenomyosis and to highlight the importance of a correct diagnosis, we studied four new cases of ACUM and 15 cases reported as juvenile cystic adenomyoma (JCA) by reviewing the literature from the last year. This entity is problematic because of a br...

SIR, In their interesting abstract on platelets and rheumatoid arthritis' Farr et al. call attention to the frequent presence of an inflammation-related thrombocytosis in rheumatoid arthritis (RA). They point out that such a finding is not specific of RA. In fact they found thrombocytosis related to disease activity also in patients affected with Crohn's disease. We reached the same conclusions...
