Delta-N formalism for the evolution of the curvature perturbations in generalized multi-field inflation
The δN formalism is considered for the calculation of the evolution of the curvature perturbations in generalized multi-field inflation models. The result is consistent with the usual calculation of the standard kinetic term. For the calculation of the generalized kinetic term, we improved the definition of the adiabatic field. Our calculation improves the usual calculation of Ṙ based on the fi...
متن کاملsin[n Delta t sin (n Delta t1)] as a source of unpredictable dynamics
We investigate the ability of the function [ ( )], where is an integer and growing number, to produce unpredictable sequences of numbers. Classical mathematical tools for distinguishing periodic from chaotic or random behaviour, such as sensitivity to the initial conditions, Fourier analysis, and autocorrelation are used. Moreover, the function { [ ( )]} ⁄ is introduced to have an uniform dens...
متن کاملTime-Mode Signal Quantization for Use in Sigma-Delta Modulators
The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولA More Efficient Use of Delta-CRLs
Delta-certificate revocation lists (delta-CRLs) were designed to provide a more efficient way to distribute certificate status information. However, as this paper shows, in some environments the benefits of using delta-CRLs will be minimal if delta-CRLs are used as was originally intended. This paper provides an analysis of delta-CRLs that demonstrates the problems associated with issuing delta...
