Cubic pythagorean fuzzy linear spaces

The first author is supported by the “CSIR” Council of Scientific and Industrial Research.Pythagorean fuzzy sets assist in handling more uncertain and vague data than fuzzy sets and intuitionistic fuzzy sets. The notion of cubic pythagorean fuzzy sets is defined by combining interval valued pythagorean fuzzy sets and pythagorean fuzzy sets In this paper, based on the notion of cubic Pythagorean fuzzy sets we initiate a new theory called cubic pythagorean fuzzy linear spaces. Inspired by the notion of Cubic linear spaces we also present P(resp. R)-union and P(resp. R) intersection of cubic pythagorean fuzzy linear spaces. The concept of internal(resp. external) cubic pythagorean fuzzy linear spaces and its properties are examined.Publisher's Versio

Some Results of Double Sequences in 2-Normed and n-Normed Spaces

The primary purpose of this paper is to introduce the notion of double sequences in 2-normed space. We provide a simple way to derive a norm from the standard 2-norm by using double sequences when a 2-normed space is given. Equivalence relation between derived norm and the usual norm are established. Using this derived norm, we examine the completeness property of a 2-normed space and we extend the results to n-normed spaces

Social welfare maximization based optimal energy and reactive power dispatch using ant lion optimization algorithm

In this paper an optimal energy and reactive power dispatch problem is solved by using the ant lion optimization (ALO) algorithm by considering the total cost minimization and social welfare maximization (SWM) objectives. Two different market models are proposed in this work, i.e., conventional/sequential market clearing and the proposed/simultaneous market clearing. In each market model, two objectives, i.e., total cost minimization and SWM are considered. The conventional social welfare (SW) consists the benefit function of consumers and the cost function of active power generation. In this paper, the conventional SW is modified by including the reactive power cost function. The reactive power cost calculation is exactly same as that in the conventional practice. The most important difference is that instead of doing cost calculation in post-facto manner as in conventional practice, simultaneous approach is proposed in this work. The scientificity and suitability of the proposed simultaneous active and reactive power methodology has been examined on standard IEEE 30 bus test system

INVESTIGATIONS ON THE RECOVERY OF TITANIUM VANADIUM AND IRON VALUES FROM THE WASTE CHILORIDE LIQUORS OF TITANIA INDUSTRY

The thesis entitled INVESTIDGATIONS ON THE RECOVERY OF TITANIUM VANADIUM AND IRON VALUES FROM THE WASTE CHILORIDE LIQUORS OF TITANIA INDUSTRY embodies the results of the investigations carried out on the solvent extraction separation of iron (III) vanadium(V) and titanium (IV) chlorides from the waste chloride liquors of titanium minerals processing industry by employing tributylphosphate (TBT) as an extractant. The objective of this study is to generate the knowledge base to achieve the recovery of iron, vanadium and titanium cvalues from multi- metal waste chloride liquors originating from ilmenite mineral beneficiation industries through selective separation and value added material developmen

Magnitude and Associated Factors for Home Delivery Among Women Who Gave Birth in Last 12 Months in Ayssaita, Afar, Ethiopia-2016. A community Based Cross Sectional Study

Introduction: Proper medical attention and hygienic conditions during delivery can reduce the risk of complications and infections that can cause the death or serious illness of the mother or newborn baby. Home deliveries are common in developing Home deliveries range from 22% in Senegal, 65% in Tanzania, 87.7% in Bangladesh and 94% in Ethiopia.Objective: To assess the magnitude and factors associated with home delivery in Ayssaita district, Afar, Ethiopia, 2016. Methods: A community based cross-sectional study was conducted in May2016 with 317 sample using structured questionnaire. Bivariate and multivariate analyses were conducted and Odds ratio with 95% CI and p value of &lt; 0.05 for statistical signifi cance were declared.Results: About 71.0% of women delivered at home and majority of them were assisted by nonskilled attendants (75.4%). The independent predictors for home delivery in this study were maternal age, maternal residence, maternal education and maternal awareness on at least one danger signs during pregnancy.Conclusion: Majority of women (74.4%) attended at least one antenatal visit from skilled health care providers during their recent pregnancy however; majority of them gave birth at home (71.0%) and assisted by non-skilled attendant. Being rural resident, illiterate, younger age, and not having least awareness on at least one danger signs were the independent predictors for home delivery. Women empowerment through educational opportunities; strengthening health extension workers to create community awareness on the importance of institutional delivery particularly for the rural pastoralist mothers are recommended.</p
