Notwithstanding the significant efforts to develop estimators of long-range correlations (LRC) and to compare their performance, no clear consensus exists on what is the best method and under which conditions. In addition, synthetic tests suggest that the performance of LRC estimators varies when using different generators of LRC time series. Here, we compare the performances of four estimators...

A product redesign approach has been developed to facilitate the product modification processes. This approach combines the idea of Function Allocation (FA), Problem Recommendation Driven Mechanism (PRDM) and the Design for Assembly (DFA) methodology to develop an effective redesign approach. The DFA is used to evaluate a product from the viewpoint of assembly and product design. The FA is used...

Using multi-fractal detrended fluctuation analysis (MF-DFA), the scaling features of wind speed time series (WSTS) could be explored. In this paper, we discuss the influence of sub-daily variation, which is a natural feature of wind, in MF-DFA of WSTS. First, the choice of the lower bound of the segment length, a significant parameter of MF-DFA, was studied. The results of expanding the lower b...

Characterizing the stratosphere as a turbulent system, temporal fluctuations often show different correlations for different time scales as well as intermittent behaviour that cannot be captured by a single scaling exponent. In this study, the different scaling laws in the long-term stratospheric variability are studied using multifractal de-trended fluctuation analysis (MF-DFA). The analysis i...

The objective of this study was to analyze the antimicrobial effect of 2% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX) by agar diffusion test and by direct exposure test. Five microorganisms: Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aernginosa, Bacillus subtilis, Candida albicans, and one mixture of these were used. These strains were inoculated in brain heart infusio...

methods this prospective observational study was conducted in a tertiary level neonatal intensive care unit, princess esra hospital, deccan college of medical sciences, hyderabad, telangana, india. consecutive intramural and extramural neonates admitted to neonatal intensive care unit with the rh-negative mother’s blood group and hyperbilirubinemia were enrolled. neonates born to rh+ve mothers ...

A method to assess micronucleus (MN) induction in Vicia faba roots by direct contact exposure to a solid matrix was developed. The procedure comprised a 5-d germination period, as in the well-known method using aqueous extracts. However, the seeds were here sown directly into the test soil whereas a culture period is necessary before exposing seedlings to a liquid medium. One soil under forest ...

In a randomized experiment with noncompliance, testing whether treatment exposure X has an effect on the final response Y is often of scientific interest. We propose a finite-population permutation-based test of the null hypothesis that X has no effect on Y within Compliers. Our method builds on tests for principal stratum direct effects described in (Nolen and Hudgens, 2011).
