    Analysis and forecasting of financial time series using artificial neural network
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Chauhan, Shikha; Pal, A.K.
    Present work entitled “ANALYSIS AND FORECASTING OF FINANCIAL TIME SERIES USING ARTIFICIAL NEURAL NETWORK” treated the issue of developing an artificial neural network model which generates a buying signal based on Golden crossover and sell signal if 50 DMA crosses below 200 DMA and also, forecasts the stock index for future. Artificial neural networks are very good in the stock market prediction as they are non-linear and complex models. In this work, we have used the artificial neural network to predict the stock index and behavior (buy or sell signal) of financial time series. The presented study comprises five chapters. The first chapter is aimed to fulfill the basic need of introducing time series, artificial neural network and the use of neural network in the time series forecasting. Chapter two accomplished majority of passed research work related with the present work. Chapter three covers the material and methods used for the present study. We have presented the neural network for the prediction and simulated it in MATLAB software. Chapter four describes the result and discussion of the encountered taken in chapter three. The work has been summarized in chapter five. Along with the finding of the study, the literature used in the course of the study has been referred under the section of literature cited. The related study may be helpful for the investors of stock market to make wise decisions so that they can have maximum profit.

    Reliability modeling of repairable systems using interval valued universal generating function
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-06) Renu; Singh, S.B.
    In this thesis authoress studied following two different models: (1) Reliability assessment of repairable parallel-series multi state system applying interval valued universal generating function. (2) Reliability evaluation of repairable weighted (u, v)-out-of-(x, y) system using interval valued universal generating function. Both models involve a comprehensive analysis of the systems using interval-valued universal generating function incorporating different types of uncertainties which have been removed by using probability intervals. In the first model, we have considered a repairable multi-state parallel-series system having two different uncertainties namely Aleatory and epistemic uncertainty. Probability intervals have been used to deal with these uncertainties. The failure rates ( ijk l ) and repair rates ( ijk m ) are taken in interval numbers. Using Laplace-Steiltjes transform probability intervals have been calculated. By using these probabilities, reliability, MTTF and sensitivity of the proposed system have been computed. In the second model, repairable weighted (u, v)-out-of-(x, y) system consisting of 6 components with two types of uncertainties has been studied. In this model different weights have been assigned to the components to evaluate the reliability and sensitivity of the system with the help of same methods as applied in model-1.

    A study of flow and heat transfer of nanofluid over a flat plate
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-05) Upreti, Himanshu; Manoj Kumar
    Recent work deals with the problem pertinent to flow and heat transfer of nanofluid flow over a flat porous plate under the influence of suction/injection, heat generation/absorption and viscous-Ohmic dissipation. The influences of these parameters and other factor governing the flow have been analyzed and their impact on velocity and thermal boundary layer is reveal through graphs. Moreover, the non-dimensional quantities i.e., skin friction coefficient and heat transfer rate (Nusselt number) have also been computed and included in this study. The study presented in the thesis includes five chapters. The first chapter aims to fulfill the basic need of introducing the various concepts and foundation needed for fluid mechanics. Chapter two throw light on majority of passed research work related with the present work. Chapter three covers the mathematical formulation of the problem and its detailed description. A proper description of used methodology, together with the details of the numerical solution is also presented. Chapter four describes the result and discussion of the considered problem taken in chapter three. The work has been summarized in chapter five. In along with the finding of the study, the literature used in the course of the study has been referred under the section of literature cited. The related study may be helpful to applied scientific fields and different branch of engineering and applied mathematics.
