Tripolar fuzzy interior ideals and tripolar fuzzy soft interior ideals over semigroups
Marapureddy Murali Krishna Rao 원광대학교 기초자연과학연구소 2020 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.20 No.3
M.Murali Krishna Rao [14] introduced the notion of tripolar fuzzy set as a generalization of fuzzy set, bipolar fuzzy set and intuitionistic fuzzy set.The tripolar fuzzy set representation is very useful in discriminating relevant elements, irrelevent elements and contrary elements. In this paper,we introduce the notion of tripolar fuzzy interior ideal,tripolar fuzzy soft ideal, tripolar fuzzy soft interior ideal over semigroup and study some of their algebraic properties.

Murali Krishna Rao, M.,Venkateswarlu, B. The Korean Society for Computational and Applied M 2016 Journal of applied mathematics & informatics Vol.34 No.5
The notion of Γ-semiring was introduced by M. Murali Krishna Rao [8] as a generalization of Γ-ring as well as of semiring. In this paper fuzzy k-ideals, k-fuzzy ideals and fuzzy-2-prime ideals in Γ-semirings have been introduced and study the properties related to them. Let μ be a fuzzy k-ideal of Γ-semiring M with |Im(μ)| = 2 and μ(0) = 1. Then we establish that M<sub>μ</sub> is a 2-prime ideal of Γ-semiring M if and only if μ is a fuzzy prime ideal of Γ-semiring M.

Y. Murali Krishna,K. Murali Krishna,Ch. Amaranatha Sarma 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.5
Signal processing takes an important role in genomic with enormous data available in public domain. Generally digital filters are applied to predict the protein and genes, but it needs to be redesigned when the characteristic frequency and periodic behavior is changed. In this paper proposed the novel adaptive algorithm which can identify the genes and proteins effectively from unified framework. First using the electron ion potential method the symbolic DNA sequences are converted in to digital signal. Secondly the filtering scheme for genomic signal processing with periodic behavior in biological sequence is introduced, which can predict and analyze the biological region that are interested in. finally the proposed adaptive filtering method is applied to recognize the exons of protein coding regions according to periodic-3 property. The exons prediction curves are obtained with Discrete Fourier Transform (DFT), Least mean square (LMS), and proposed Fast Recursive least Mean Square (F-RLS) algorithms. It is shown that proposed method shows efficiency in convergence of identification and precise prediction of exons regions compared to existed methods.
On fuzzy $k-$ideals, $k-$fuzzy ideals and fuzzy $2-$prime ideals in $\Gamma -$semirings
M. Murali Krishna Rao,B. Venkateswarlu 한국전산응용수학회 2016 Journal of applied mathematics & informatics Vol.34 No.5
The notion of $\Gamma -$semiring was introduced by M. Murali Krishna Rao \cite{8} as a generalization of $\Gamma -$ring as well as of semiring. In this paper fuzzy $k-$ideals, $k-$fuzzy ideals and fuzzy-$2-$prime ideals in $\Gamma -$semirings have been introduced and study the properties related to them. Let $\mu$ be a fuzzy $k-$ideal of $\Gamma -$semiring $M$ with $| Im(\mu)| =2$ and $\mu(0)=1.$ Then we establish that $M_{\mu}$ is a $2-$prime ideal of $\Gamma -$semiring $M$ if and only if $\mu$ is a fuzzy prime ideal of $\Gamma -$semiring $M.$

Geopolymer binders fascinate the attention of researchers as a replacement to cement binder in conventional concrete. One-ton production of cement releases one ton of carbon-dioxide in the atmosphere. In the replacement of cement by geopolymer material, there are two advantages: one is the reduction of CO<sub>2</sub> in the atmosphere, second is the utilization of Fly ash and Ground granulated blast furnace slag (GGBFS) are by-products from coal and steel industries. This paper focuses on the mechanical properties of steel fiber reinforced geopolymer concrete. The framework considered in this research work is geopolymer source (Fly ash, GGBFS and crimped steel fibre) and alkaline activator which consists of NaOH and Na<sub>2</sub>SiO<sub>3</sub> of molarity 8M. Here the Na<sub>2</sub>SiO<sub>3</sub> / NaOH ratio was taken as 2.5. The variables considered in this experimental work include Binder content (360,420 and 450 kg/m<sup>3</sup>), the proportion of Fly ash and GGBS (70-30, 60-40 and 50-50) for three different grades of Geopolymer concrete (GPC) GPC 20, GPC 40 and GPC 60. The percentage of crimped steel fibres was varied as 0.1%, 0.2%, 0.3%, 0.4% and 0.5%. Generally, the inclusion of steel fibres increases the flexural and split tensile strength of Geopolymer concrete. The optimum dosage of steel fibres was found to be 0.4% (by volume fraction).

In this paper we consider the set of all n + 1-tuples of real numbers, not necessarily all distinct, in the decreasing order from the unit interval under the usual ordering of real numbers, always including 1. Such n + 1-tuples inherently arise as the membership values of fuzzy subsets and are called keychains. An natural equivalence relation is introduced on this set and the equivalence classes of keychains are studied here. The number of such keychains is finite and the set of all keychains is a lattice under the coordinate-wise ordering. Thus keychains are subchains of a finite chain of real numbers in the unit interval. We study some of their properties and give some applications to counting fuzzy subsets of finite sets.

Digital human modeling enables engineers in product development to address questions of ergonomics and human factors early on inthe development. To build more accurate Digital human models (DHMs), the physiological standard reference data are necessary. Weinvestigated the effects of lifting loads beside the body compared to in front of the body. Forty healthy subjects performed eight liftingtasks with combinations of two postures, and four loads. The magnitude of the erector spinae muscle activity: Median frequency (MF)and Normalized root-mean-square (N-RMS) was estimated using surface electromyography. The magnitude of the lumbar spinal loadsabout lumbar vertebrae was estimated using DHM software. The effect of the moment arms (5, 6, 7.5 and 8.5 cm) on the lumbar spinalloads was estimated biomechanically. Lifting loads beside the body significantly (p < 0.01) reduced the muscle fatigue, muscle activity,and spinal loads. The increased moment arms resulted in the reduction of compression (5-13%) and muscle force (16-41%). The resultpresented in this study could be used to build more accurate DHMs.

In this study, we investigate a facile synthetic method for the new nanoplate structure of YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> with enhanced luminescence intensity. The shape of YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> nanocrystals can be controlled by changing the synthesis conditions of the NaOH concentration, reaction time, and surfactant. The concentration of NaOH determines the final structure of YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP>. By increasing the NaOH concentration from 0.25 mmol to 2.5 mmol, YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> nanoplates transform into NaYF4:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> nanoparticles; in the absence of NaOH, the nanoplate structure of YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> changes to particles. The YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> nanoplates show luminescence efficiency much greater than that of the spherical YF3:Yb<SUP>3+</SUP>/Er<SUP>3+</SUP> nanocrystals.</P></▼2>
