Title: MHD Stagnation-Point Flow towards a Heated Stretching Sheet Authors: Uddin, M S; Wahiduzzman, M; Sazad, M A K; Pk, W. Ali Abstract: Boundary layer flow near a stagnation-point and heat transfer over a stretching sheet is very important due to its ever increasing wide range of applications. A similarity analysis is proposed to investigate the structure of the boundary layer near the stagnation-point region scaling group of transformation. A special form of Lie group transformations will be applied to find the similarity solution. The main advantage of this method is that no ad hoc assumptions or a prior knowledge of the equations under investigation is needed. Similarity solutions reduce the number of independent variables of the problem. As a result the governing non-linear partial differential equations reduce to non-linear ordinary differential equations. These equations are solved numerically using the Nactsheim-Swigert shooting iteration technique together with Runge-Kutta six order iteration scheme. Numerical results are obtained for the velocity and temperature. The obtained results are presented graphically and corresponding physical aspect of the problem are discussed. Description: 93-105

Title: Tripled Coincidence Point Results In Partially Ordered Probabilistic Metric Spaces Authors: Choudhury, Binayak S; Das, Krishnapada; Bhandari, Samir Kumar; Das, Pradyut Abstract: In this paper we establish a tripled coincidence point theorem in probabilistic metric spaces. Tripled fixed points are extensions of coupled fixed points, a concept which has been in focus in recent times. The result is supported with an example Description: 9-22

Title: Synthesis and Properties of Polyaniline Samarium Nanocomposite Authors: Gupta, K; Jana, P C; Meikap, A K Abstract: The main objective of this investigation is to study the effect of samarium nanoparticles on the optical and electrical transport properties of polyaniline. Polyaniline-samarium nanocomposite has been prepared by chemical oxidative polymerization of aniline in presence of samarium nanoparticles. Average grain size lies in the range 30-40 nm. A red shift in the optical absorption is obtained. Temperature and magnetic field affect the electrical transport properties of our samples. Conductivity and magnetoconductivity have been increased with temperature Description: 209-216

Title: Transportation Time Minimization: An Algorithmic Approach Authors: Sharif Uddin, M Abstract: In this paper, a transportation algorithm is applied to determine the minimum transportation time. The algorithm determines the Initial Basic Feasible Solution (IBFS) of Transportation Problem (TP) to minimize time. Herein, the Distribution Indicators (DI) is calculated by the difference of the greatest time unit and the nearest-to-the-greatest time unit. Then the least entry of the Transportation Table (TT) along the highest DI is taken as the basic cell. The result with an elaborate illustration demonstrates that the method presented here is effective in minimizing the transportation time. Description: 59-64
