In this paper, we present a new public key scheme which is a combination of RSA variant namely the Dependent-RSA (DRSA) and the general formulation of DGDLP. The security of this scheme depend equally on the integer factorization of n and the discrete logarithm on Zn, where n is a product of two large primes and Zn is the multiplicative group modulo n. The scheme is a randomized algorithm and i...

The background field approach to multi-loop calculations in gauge field theories is presented. A relation between the gauge-invariant effective action computed using this method and the effective action of the conventional functional approach is derived. Feynman rules are given and renormalization is discussed. It is shown that the renormalization programme can be carried out without any refere...

This talk presents details of the calculation of two-loop corrections to heavy baryon currents containing one heavy quark in leading order of the 1/mQ-expansion, i.e. in the limit of Heavy Quark Symmetry (HQS). The calculations lead to the determination of the anomalous dimension of these currents. I also discuss problems with different γ5-schemes and their solution by the finite renormalizatio...

Success in higher education depends on students’ ability to meet the writing requirements of their chosen courses, and in many cases this involves adapting to the literacy practices of particular disciplines. While research into professional academic discourse suggests that it may reflect differences in disciplinary culture and epistemology, there has been relatively little investigation of dis...

We consider the celebrated Cucker-Smale model in finite dimension, modelling interacting collective dynamics and their possible evolution to consensus. The objective of this paper is to study the effect of time delays in the general model. By a Lyapunov functional approach, we provide convergence results to consensus for symmetric as well as nonsymmetric communication weights under some structu...

Fundamental changes in the market environment force insurance intermediaries to redefine their roles. This article focuses on the future functions of brokers, which are analyzed from a functional as well as a customer-oriented perspective. To cope with the limitations of current intermediation research, the customer-value approach is applied as an alternative framework. This approach suggests t...

Wemake the first attempt to discuss stability and boundedness of solutions to stochastic Volterra integrodifferential equations with infinite delay (IDSVIDEs). By the Lyapunov-Krasovskii functional approach, we get kinds of sufficient criteria for stability and boundedness of solutions to IDSVIDEs. The main innovation here is that stochastic systems with infinite delay can retain stability and ...

Dominance-based Rough Set Approach (DRSA) has been proposed as an extension of the Pawlak’s concept of Rough Sets in order to deal with ordinal data [see [2, 3]]. Ordinal data are typically encountered in multi-attribute decision problems where a set of objects (also called actions, acts, solutions, etc.) evaluated by a set of attributes (also called criteria, variables, features, etc.) raises ...

Dominance-based Rough Sets Approach (DRSA) is a useful tool for multi-criteria classification problems solving. Parallel computing is an efficient way to accelerate problems solving. Computation of approximations is a vital step to find the solutions with rough sets methodologies. In this paper, we propose a matrix-based approach for computing approximations in DRSAand design the corresponding ...
