(R1997) Distance Measures of Complex Fermatean Fuzzy Number and Their Application to Multi-criteria Decision-making Problem
Multi-criteria decision-making (MCDM) is the most widely used decision-making method to solve many complex problems. However, classical MCDM approaches tend to make decisions when the parameters are imprecise or uncertain. The concept of a complex fuzzy set is new in the field of fuzzy set theory. It is a set that can collect and interpret the membership grades from the unit circle in a plane instead of the interval [0,1]. CFS cannot deal with membership and non-membership grades, while complex intuitionistic fuzzy set and complex Pythagorean fuzzy set works only for a limited range of values. The concept of a complex Fermatean fuzzy set (CFFS) is proposed to deal with these problems. This paper presents the main ideas of CFFN and its properties are studied. The proposed new distance measures for real-world problems are also discussed. A comparative study of the proposed new work is also conducted
Effects of selected asana practices on flexibility and balance among school level taekwondo athlete
To achieve the purpose of this study, a school level taekwondo Athlete were selected from Premier Vidya Vikash School, Coimbatore. The selected (N= 30) thirty subjects were randomly divided into two equal groups (n-15), experimental group named as asana programme and control group. The pre-test was conducted on selected physiological variables (flexibility and balance), for all the groups. The readings were carefully regarded in the respective unit as pre-test score. After pre-test experimental group was treated with sit and reach test and stork balance test programme and the control group was not treated with any special programme. They kept as a control group. The subject was tested on criterion measures on flexibility – Sit and Reach Test and balance- Stroke balance the readings were carefully recorded in their respective units as pre-test score. The experimental groups underwent the respective training schedule one half hour per day in the morning session for a period of six weeks. After completion of 6 weeks of training, all the two groups were tested again on flexibility and balance the scores were recorded in their respected units as post-test scores. The pre and post test scores were taken for appropriate statistical analysis. In order to find out the significant changes if any paired ‘t’ ratio was be applied 0.05 level of confidence. The present study experimented effects of selected asana practices on flexibility and balance among school level taekwondo athlete. The result of this study indicated that there was is a change in flexibility and balance due to the proper planning, preparation, and execution of the training package given to the athlet
Effect of low temperature on the survival of edible oyster Crassostrea madrasensis during transportation and storage
The survival of the tropical edible oyster (Crassostrea madrasensis)
was examined under the condition of ice-storage in a rectangular
thermocol-transport box for a period of 48 h. A total of 100
two-year old farmed oysters were used for the experimental
transportation. Inside the box, all oysters were arranged in four
layers covered with wet-gunny bags and lined on the top and
bottom with ice. Surface and bottom temperature of the
transport box varied from 9.7 to 25.2˚ C and 9.7 to 28.4˚ C
respectively during the 48 h exposure. The patterns of changing
temperature at both surface and bottom were found to be
different. Recoveries of the oysters at every two hours till 48h
were monitored by taking random samples from the box. All the
oysters recovered within 1 h of being placed back into seawater
and there was close to 100% recovery within 2 hours
Characterization of semigroup by rough interval pythagorean fuzzy set
This paper expose a study on rough interval valued pythagorean fuzzy sets in semigroups. We characterize rough interval valued pythagorean fuzzy sets by an example. Characterize composition of two interval valued pythagorean fuzzy sets. Introduce rough interval valued pythagorean fuzzy left(right, bi-, interior-,(1,2)-)ideals in semigroups. Moreover we prove an interval valued pythagorean fuzzy set is an upper rough interval valued pythagorean fuzzy left(right) ideal of semigroup also we give an example for converse of this is not true. Lower and upper approximation of an interval valued pythagorean fuzzy ideal of semigroup is an interval valued pythagorean fuzzy ideal of semigroup.Publisher's Versio
OPERATIONS ON INTERNAL AND EXTERNAL CUBIC SOFT MATRICES
In this paper, we define some operations on internal and external cubic soft matrices. We also characterized some of its algebraic properties
Assessment of bio-accumulation of bacteria in oysters from shellfish growing waters in Ashtamudi Lake (Kerala, India): A RAMSAR wetland
Oysters are commercially cultured from the Ashtamudi Lake in India, and support 12,000 tonnes of
bivalve fisheries/year. Oysters and oyster growing waters were sampled from July 2012 to June 2013
for analysis of total coliforms (TC), faecal coliforms (FC), Escherichia coli, faecal Streptococci (FS) and total
plate counts (TPC). E. coli MPN values in oyster growing waters were below the threshold limits set by
the USFDA and EU during the months of December to April. Seasonally, the highest MPN values for E.
coli were obtained during the monsoon season (June–September), and this trend gradually decreased
during the post-monsoon (October–January) and pre-monsoon (February–May) periods. E. coli displayed
a significant (p < 0.01) variation in accumulation during different seasons. A strong negative correlation
(R2 = −0.70, p < 0.05) between temperature and E. coli numbers in oysters was observed, while rainfall
and E. coli were positively correlated (R2 = 0.695, p < 0.05). Hence, we strongly recommend depuration
and proper cooking of oysters before consumption during the monsoon season
MAJORIZATION OF MATRICES
It is shown that under certain conditions the column majorization of matrices is reversed for the column majorization of their corresponding Moore-Penrose inverses and preserved for the column majorization of their powers. The condition for column majorization of block matrices is determined
Constraints in the Adoption of Eco Friendly Conservation Practices
Adoption of Eco Friendly Conservation Practices requires strong attitude and good knowledge level. Further, the adoption of Eco Friendly Conservation Practices has put fourth many constraints. This study was conducted in The Nilgiris district to assess the constraints and suggestions to overcome the constraints in the adoption of Eco Friendly Conservation Practices. Thus, to analyse the constraints Garett ranking method was used (Garett, H.E. et al 1973). The study revealed that the constraints of labour scarcity, Lack of skill about the eco friendly conservation practices, lack of credit facilities, high risk,Insect pest and diseases management, Lack of awareness of agro environmental problems and farmer’s attitude towards the Eco Friendly Conservation Practices are the major constraints in the adoption of Eco Friendly Conservation Practices.The study suggests educational, extension & training strategies for fostering the adopted of ECO friendly Conservation Practices
Adoption and Impact of Eco-Friendly Conservation Practices in The Nilgiris District of Western Ghats
The study was under taken to find out the relationship between the profile of the farmers of The Nilgiris district and the impact in their adoption of Eco Friendly Conservation Practices. The study revealed that educational status, risk orientation, training undergone, progressiveness, self reliance, innovativeness and contact with extension agency were found to have positively contributed to the adoption of Eco Friendly Conservation Practices. With respect to impact, majority of the farmers opined that the cost of cultivation decreased, followed by increased farmers confidence level, improved fertility status of the soil and improved biodiversity in the farm fields
