Writer identification is a popular research field in many languages. Since alphabets of different language have different pattern, the methods are dependent on the language. Handwriting of a person has some features which are unique to every person and can be used for identification. Most of the research activities for writer identification are based on English documents and the research activities for Tamil handwriting are thin and databases are not available. In this paper, a method is proposed to identify a writer from the scanned images of Tamil handwritten text. Our approach is based on texture analysis where each writer's handwriting is treated as a different texture. The method is text independent and based on the features extracted from gray level co-occurrence matrix of the scanned image. Handwriting samples from 70 writers were used and the documents were scanned with 150 dpi. © 2011 IEEE.

Human Interaction is an essential aspect to recognize communicative data in various applications including medical diagnosis and human-computer interaction. Mining human Interaction in meetings is very helpful to determine reactions of persons in different scenarios. Behavior denotes the nature of the person and mining helps to examine the exhibition of one's opinion. This research work presents a novel technique to mine frequent patterns of human interaction based on the meetings. In this proposed approach, human interaction flow in a discussion session is denoted as a tree. Tree-based interaction mining of Weighted Interesting Pattern mining algorithms are designed to analyze the structures of the trees and to extract interaction flow patterns. The experimental results shows that several interesting patterns are efficiently extracted which are useful for the interpretation of human behavior in meeting discussions, such as determining frequent interactions, typical interaction flows, and relationships between different types of interactions. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

Objective: To determine the possible bioactive components of the ethanolic extract of leaves of Elaeocarpus serratus ( E. serratus). Methods: The present research was carried out by using GC-MS analysis, while mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology and Wiley library. Results: Thirty components from leaves of the above said plant were identified. The active principles with their retention time, molecular formula, molecular weight and concentration (%) in the ethanol extracts of leaf of E. serratus are obtained. Conclusions: This is the first report of documentation of active constituents from leaves of E. serratus. The research reveals the potential of E. serratus leaves as a good source of bioactive compounds such as fatty acid esters, alcohols, hydrocarbons, aldehydes, alkenes, fatty acids and amides that justify the use of this plant for its various ailments by traditional practitioners. © 2013 Asian Pacific Tropical Biomedical Magazine.

Medicinal plants are of great importance to the health of individuals and communities. A large number of plants are claimed to possess the anti-diabetic, anti-fertility, antihyperlipidaemic, anti-inflammatory, anti-cancer, hepatoprotective and immunomodulatory activities in the traditional therapeutic systems. It is now believed that nature has given the cure of every disease in one way or another. Clitoria ternatea a valuable medicinal plant possess many bioactive principles which includes diabetes mellitus, chronic bronchitis, goitre, mucous disorders and leprosy. The ethanolic extract of leaves of C. ternatea was investigated for its phytochemical properties and analysis for its active chemical ingredients. For qualitative and quantitative phytochemical analysis the ethanol extract of C. ternatea acts as a source of therapeutic agent.

Trichosanthes dioica and Clitoria ternatea were traditional plants that were used for the treatment of diabetes mellitus, stress and depressant. The present work was undertaken to evaluate the antihyperglycemic effect of individual and combined ethanolic extracts of these two different herbs to study the blood glucose level and the activities of some carbohydrate metabolizing enzymes in liver of normal and STZinduced diabetic rats. The extracts were administered orally to the diabetic rats for 28 days, resulted in significant decrease of blood glucose and decrease the activities of glucose-6-phosphatase and fructose-1,6-bisphosphatase and increase the activities of glucokinase, pyruvate kinase and glucose-6-phosphate dehydrogenase. From the studyn it was revealed that combined plant extract was more effective for treating diabetes mellitus.

We introduce certain types of intuitionistic fuzzy directed hypergraphs (IFDHGs) including core, simple, elementary, sectionally elementary IFDHGs and (Formula presented.) -tempered IFDHGs, and present some of their properties. We introduce the concept of transversals of IFDHGs and describe some of their properties. We also prove that if (Formula presented.) is elementary, support simple and simply ordered then (Formula presented.) is an (Formula presented.) -tempered IFDHG. © 2014, Springer-Verlag Berlin Heidelberg.

Atanassov [1][9][10] defined Intuitionistic Fuzzy Graphs(IFGs) using five types of Cartesian products. In this paper IFGs so defined are named. Homomorphism, weak isomorphism and co-weak isomorphism of minmax IFGs are defined with suitable illustrations. Some of the properties of isomorphism on IFG and isomorphism on strong IFG are also analyzed. © 2011 IEEE.

Linear regression analysis in an intuitionistic fuzzy environment using intuitionistic fuzzy linear models with symmetric triangular intuitionistic fuzzy number (STriIFN) coefficients is introduced. The goal of this regression is to find the coefficients of a proposed model for all given input-output data sets. The coefficients of an intuitionistic fuzzy regression (IFR) model are found by solving a linear programming problem (LPP). The objective function of the LPP is to minimize the total fuzziness of the IFR model which is related to the width of IF coefficients. An illustrative example is also presented to depict the solution procedure of the IFR problem by using STriIFNs. © 2012 Springer Science+Business Media New York.

Intuitionistic fuzzy graph theory is finding an increasing number of applications in modeling real time systems where the level of information inherent in the system varies with different levels of precision. Intuitionistic fuzzy models are becoming useful because of their aim in reducing the differences between the traditional numerical models used in engineering and sciences and the symbolic models used in expert systems. In this paper, a method for finding the shortest hyperpath in an intuitionistic fuzzy weighted hypergraph is proposed. An intuitionistic fuzzy number is converted into intuitionistic fuzzy scores. To find the intuitionistic fuzzy shortest hyperpath in the network, ranking is done using the scores and accuracy. © 2013 Elsevier B.V.


Trichosanthes dioica and Clitoria ternatea were traditional plants that were used for the treatment of diabetes mellitus, stress and depressant. The present work was undertaken to evaluate the antihyperlipidemic effect of individual and combined ethanolic extracts of these two different herbs to study the acute oral toxicity study, body weight, oral glucose tolerance test and serum lipids in normal and STZ-induced diabetic rats. The extracts were administered orally to the diabetic animals for 28 days, resulted in a significant increase of body weight, decrease of blood glucose, total cholesterol, triglycerides, LDL, VLDL and phospholipids and significant increase of HDL. From the study it was revealed that combined plant extract was more effective for controlling serum lipids.
