<p>Mapana, Journal of Sciences, is an instrument to generate greater interest, deeper insight and quest in the minds of students, teachers and researchers in the field of science. It provides space for an indepth analysis of issues, comments and concerns on scientific problems and events, research papers and articles of primary and secondary nature which would enable us to have a share in creating a more harmonious world.</p>en-USmapana@christuniversity.in (Anil Pinto)mapana@christuniversity.in (Joseph Varghese)Sun, 01 Jul 2018 00:00:00 +0000OJS 3.0.2.0http://blogs.law.harvard.edu/tech/rss60 On SD-Harmonious Labeling
http://journals.christuniversity.in/index.php/mapana/article/view/1827
<p>A graph G is said to be SD-harmonious labeling if there exists an injection f: V(G) -> {0,1,2,...,q} such that the induced function f*: E(G) ->{0,2,...,2q-2} defined by f(uv)=S+D (mod 2q) is bijective, where S=f(u)+f(v) and D=|f(u)-f(v)|, for every edge uv in E(G). A graph which admits SD-harmonious labeling is called SD-harmonious graph. In this paper, we investigate SD-harmonious labeling of path related graphs, tree related graphs, star related graphs and disjoint union of graphs.</p>A Lourdusamy, PhD, S Jenifer Wency, F Patrick

http://journals.christuniversity.in/index.php/mapana/article/view/1829
<p>Pregnancy is the typical stage in every life cycle of woman where many biochemical and physiological changes takes place in all the systems. The adaptation of these changes by the human body differs from one individual to another and it may results in many threats. Gestational Diabetics (GD) is one of the serious threats faced by women during pregnancy. Biologically stated it is the state of glucose intolerance. Presently pregnant women are getting highly affected by GD due to environmental changes and lifestyle variants. The outbreak of GD is the resultant of several mixes of factors which are categorized as genetic, environmental, social and behavioural. The mitigation of this diabetic condition is very essential as it affects the foetus and the mother. The consequential impacts of the factors of GD have to be determined to initiate the preventive measures and to devise the curative medications in accordance to it. This paper introduces the concept of linguistic average super fuzzy cognitive map (LASFCM) which makes use of expert’s opinion in terms of linguistic variables to find the substantial outbreak of GD.</p>Nivetha Martin

http://journals.christuniversity.in/index.php/mapana/article/view/1830
<p>The concept of stability of a class of fractional-order linear system is considered in this paper. Existing sufficient conditions are assumed to guarantee the stability of linear models with the Caputo fractional derivatives. The results have been developed by using the concept of Laplace transform, and approximations of Mittag-Leffler. Furthermore, results concerning asymptotical stability of linear fractional-order models are also achieved. The proposed method is based upon Eigen values and the characteristic polynomials. Numerical illustrations are specified to exhibit effectiveness of the proposed method.</p>S Priyadharsini
