Optimal Lower Generalized Logarithmic Mean Bound for the Seiffert Mean

open access: yesJournal of Applied Mathematics, 2013
We present the greatest value p such that the inequality P(a,b)>Lp(a,b) holds for all a,b>0 with a≠b, where P(a,b) and Lp(a,b) denote the Seiffert and pth generalized logarithmic means of a and b, respectively.

A Sharp Double Inequality between Seiffert, Arithmetic, and Geometric Means [PDF]

open access: yesAbstract and Applied Analysis, 2012
For fixed s ≥ 1 and any t1, t2 ∈ (0,1/2) we prove that the double inequality Gs(t1a + (1 − t1)b, t1b + (1 − t1)a)A1−s(a, b) < P(a, b) < Gs(t2a + (1 − t2)b, t2b + (1 − t2)a)A1−s(a, b) holds for all a, b > 0 with a ≠ b if and only if and . Here, P(a, b), A(a, b) and G(a, b) denote the Seiffert, arithmetic, and geometric means of two positive ...

Improvements of bounds for the Sándor–Yang means

open access: yesJournal of Inequalities and Applications, 2019
In the article, we provide new bounds for two Sándor–Yang means in terms of the arithmetic and contraharmonic means. Our results are the improvements of the previously known results.

Data Streams from the Low Frequency Instrument On-Board the Planck Satellite: Statistical Analysis and Compression Efficiency [PDF]

open access: yes, 2000
The expected data rate produced by the Low Frequency Instrument (LFI) planned to fly on the ESA Planck mission in 2007, is over a factor 8 larger than the bandwidth allowed by the spacecraft transmission system to download the LFI data.

On a class of new means including the generalized Schwab-Borchardt mean

open access: yesJournal of Inequalities and Applications, 2017
The so-called Schwab-Borchardt mean plays an important role in the theory of (bivariate) means. It includes a lot of standard means, such as the logarithmic mean, the first and second Seiffert means and the Neuman-Sándor mean.

Pulmonary effects of inhalation of spark-generated silver nanoparticles in Brown-Norway and Sprague-Dawley rats [PDF]

open access: yes, 2016
The increasing use of silver nanoparticles (AgNPs) in consumer products is concerning. We examined the potential toxic effects when inhaled in Brown-Norway (BN) rats with a pre-inflammatory state compared to Sprague-Dawley (SD) rats.We determined the ...

The monotonicity results and sharp inequalities for some power-type means of two arguments [PDF]

open access: yes, 2012
For $a,b>0$ with $a\neq b$, we define M_{p}=M^{1/p}(a^{p},b^{p})\text{if}p\neq 0 \text{and} M_{0}=\sqrt{ab}, where $M=A,He,L,I,P,T,N,Z$ and $Y$ stand for the arithmetic mean, Heronian mean, logarithmic mean, identric (exponential) mean, the first ...

Sources of the Radio Background Considered [PDF]

open access: yes, 2010
We investigate different scenarios for the origin of the extragalactic radio background. The surface brightness of the background, as reported by the ARCADE 2 collaboration, is several times higher than that which would result from currently observed ...
