Recently Tate pairing and its variations are attracted in cryptography. Their operations consist of a main iteration loop and a final exponentiation. The final exponentiation is necessary for generating a unique value of the bilinear pairing in the extension fields. The speed of the main loop has become fast by the recent improvements, e.g., the Duursma-Lee algorithm and ηT pairing. In this pap...

background and objectives: enteropathogenic escherichia coli (epec) divided into two groups typical and atypical (aspect). the main virulence genes are located in a pathogenicity island called lee ( locus of enterocyte effacement ). lee frequently inserted in trna genes of selc , pheu and phev in the bacterial chromosome. tepec and aepec strains have some differences in their pathogenicity. the...

Studien zeigen, dass in der Industrie großer Verbesserungsbedarf im Bereich der Testprozesse besteht. Um aber die Prozesse gezielt und wirksam verbessern zu können, ist eine Erhebung des Ist-Prozesses erforderlich. In diesem Artikel wird ein Vorgehen bei einer solchen Ist-Prozess-Erhebung anhand eines Kriterienkatalogs vorgestellt.
