No full textOn Symmetry Analysis and Exact Wave Solutions of New Modified Novikov Equation
No full textIn this paper, we study a new modified Novikov equation for its classical and nonclassical symmetries and use the symmetries to reduce it to a nonlinear ordinary differential equation (ODE). With the aid of solutions of the nonlinear ODE by using the modified (G/G)-expansion method proposed recently, multiple exact traveling wave solutions are obtained and the traveling wave solutions are expressed by the hyperbolic functions, trigonometric functions and rational functions
Exploration of sexual dimorphism and bilateral asymmetry in finger print patterns of North Indian population: A cross sectional study
No full textIntroduction- The fingerprints are most dependable and acceptable dermatoglyphic traits for personal identification The current study is an attempt to observe the percentage frequency distribution of patterns of fingerprint bilaterally as well as digit wise, to assess the predominant pattern type, besides, evaluating the statistically significant gender variations. This study may enhance the authenticity of finger print patterns in identifications of suspects. Material & method- The study sample was consisting of fingerprints of 600 medical students of Punjab, India. The subjects were aged between 17–25 years and male female ratio was 1:1. Fingerprints were recorded by the ink and roller method of Cummins and Midlo and analysed manually by using Henry`s classification. Appropriate statistical tests were applied to achieve aim of study. Result- This cross- sectional study revealed that the most common finger print pattern of both hands was Loops (L-51.6%, R-53.3%), followed by whorls (L-38.6%, R-38.2%), arches (L-8.8%, R- 6.7%) and composites (L-1.0%, R-1.8%) respectively. Each digits show preferences for specific patterns.Discussion- The current study showed insignificant bilateral difference and significant sexual dimorphism in the distribution frequency of the finger print which might be caused by differences in heritability and developmental variation among sexe
Two-Warehouse Partial Backlogging Inventory Model For Deteriorating Items With Ramp Type Demand
No full textThis paper deals with two warehouse system for deteriorating items with ramp type demand. In this inventory model initially demand is considered to be linear function of time and it became constant after a finite time parameter. Holding cost assume to be constant in both warehouse. Partial backlogging is allowed. The proposed model is developing to minimize the total inventory cost which includes holding cost, backlogging cost, lost sale cost, and deterioration cost. Here three cases are taken into consideration depending on time where demand becomes constant. This is only an analytic approach towards the model
Inversion of GDS data of Northwest Himalaya using EM2INV
No full textThis paper reviews the validity of earlier models obtained after quantitative interpretation of GDS data and presents a fresh model using the inversion scheme EM2INV. The 2-D inversion of data is more objective than the earlier interpretation performed by using trial and error method. The inversion results indicate that the present model differs from the earlier ones. The reason could be that available GDS data are sufficient only for deriving the horizontal variation of subsurface resistivity. In order to study the vertical resistivity variation additional MT sounding data would be required. It would therefore be desirable to carry out MT survey in the specified area. A more comprehensive/appropriate model could be derived from joint inversion of GDS and MT data
EM2INV - a finite difference based algorithm for two-dimensional inversion of geoelectromagnetic data
No full textThe paper presents an efficient finite difference based 2D-inversion algorithm, EM2INV, for geoelectromagnetic data. The special features of the algorithm are • optimal grid generation based on grid design thumb rules, • finite domain boundary conditions, • interpolation matrix that permits generation of response at observation points different from grid points, • Gaussian elimination forward matrix solver, that enables reuse of already decomposed coefficient matrix, • super-block notion that reduces the number of blocks with unknown resistivities and, in turn, the size of Jacobian matrix and • bi-conjugate gradient matrix solver for inverse problem which circumvents the need of explicit Jacobian matrix computation. The algorithm is tested rigorously by setting up exercises of diverse nature and of practical significance. The stability of the algorithm is established by inverting the synthetic response corrupted with Gaussian noise. The inversion experiments are aimed at studying • relative performance of response functions, • inversion quality of E- and B-polarization data, • efficacy of single and multi-frequency data inversion, • minimum number of frequencies and observation points needed for successful data inversion. It has been observed that the Magneto-telluric data deciphers better the vertical position of the target and Geomagnetic Depth Sounding data deciphers the horizontal variations in a better way. The conductive and resistive bodies are better resolved by inversion of E- and B-polarization data respectively. The results of multi-frequency inversion imply that the increase in the number of frequencies does not necessarily enhance the inversion quality especially when the spread of observation points is sufficiently large to sense the target. The study of a minimum number of observation points highlights the importance of single point inversion that furnishes useful information about the inhomogeneity
