The aim of this paper is to present the detailed description of the working and application of ‘real-time signature verification’ using clustering and statistical analysis. The entitled system works faster and efficiently involving two processes, i.e., ‘preprocessing’ and ‘feature matching’ such that ‘noise reduction,’ ‘image normalization,’ and ‘skeletonization’ are carried out in preprocessing after which the input image is stored in the database. When the sample inputs new signature, ‘feature matching’ takes place, comprising brute force and sift algorithm, and matches the signature according to the cluster values present in the stored sample signature. The approach is fast efficient and authentic, which can be implemented in certain core areas. We have proposed integrated signature verification system, in which the brute force and sift algorithm are implemented in order to perform the matching. An integrated verification system not only provides a way to compare and match an online signature against an online signature but also improves the system performance in those cases where both static and dynamic features are available. © Springer India 2014.

Selenium containing amino acids are known to play numerous key biological roles in various lifesupporting processes. In the current theoretical investigation DFT(B3LYP) and MP2 methods are used to study the gas phase conformers of the selenomethionine molecule in view of their relative stabilities, theoretically predicted harmonic frequencies, HOMO-LUMO energy gaps, rotational constants, and dipole moments. The number and type of intramolecular H-bond interactions existing in the selenomethionine conformers, which play key roles in determining the energy of the conformers, are also analyzed. The predicted geometries as well as the relative stabilities of the conformers suggest that the structural aspects and energies of the conformers may depend on the level of theory and the size of the basis set used. A comparison of the vibrational frequencies furnished in this study with the previous experimental and theoretical results obtained at MP2/6-31++G(d,p) and B3LYP/6-311++G(d,p) levels promotes the interpretation of the vibrational spectroscopy data on biologically relevant molecules. © 2015 Pleiades Publishing, Ltd.

Reduplication is an important phenomenon in language studies especially in Indian languages. The definition of reduplication is the repetition of the smallest linguistic unit partially or completely i.e. repetition of phoneme, morpheme, word, phrase, clause or the utterance as a whole and it gives different meaning in syntax as well as semantic level. The reduplicated words has important role in many natural language processing (NLP) applications, namely in machine translation (MT), text summarization, identification of multiword expressions, etc. This article focuses on an algorithm for identifying the reduplicated words from a text corpus and computing statistics (descriptive statistics) of reduplicated words frequently used in Bengali. © Springer International Publishing Switzerland 2015.

The pile group foundation is a geotechnical composite construction, consisting of the three elements-piles, pile cap and the soil, which is applied for the foundation of tall buildings in an increasing number. The behavior of the foundation system is determined by complex interaction effects between the elements and an understanding of these effects is essential for a reliable design. This study presents the three dimensional finite element analysis of pile group foundation under lateral load by using ANSYS software. The soil is modeled to be pure clay and is assumed as homogeneous and isotropic in the analysis. Elasto-Plastic behavior of the soil is numerically modeled to follow Drucker-Prager Yield criterion. The study does not take into account the development of pore water pressure in the soil since the load applied is instantaneous. A parametric study was conducted to study the behavior of pile groups under lateral load with various configurations. The effect of pile length, pile diameter and configuration of piles in the group were studied. In this study, the spacing of piles and length to diameter (L/D) ratio were altered. © 2016 ejge.

Water quality index (WQI) is a dimensionless number that combines multiple water quality factors into a single number by normalizing values to subjective rating curves. The present work is aimed at assessing the Water Quality Index (W.Q.I) of surface water of Bhilai Steel Plant industrial area. Physicochemical parameters were monitored for the calculation of W.Q.I for the summer seasons 2011. The physicochemical parameters namely pH, Total hardness, TDS, Calcium, Chloride, Sulphate, Phosphate, Sodium, Potassium, EC and DO was determined and it is found that their values were within the permissible limits on the other hand total alkalinities and magnesium values were exceeding the permissible limits as prescribed by Indian Standards. The analysis reveals that the surface water of the area needs some treatment before consumption, and it also needs to be protected from the perils of contamination. Source
