A Study on Common Fixed Point and Invariant Approximation Theorems for Mappings Satisfying Generalized Contraction Principle

We prove common fixed point theorems for weakly compatible mappings satisfying a generalized contraction principle by using a control function. As an application, we have established invariant approximation result. Our theorems generalize recent results existing in the literature. Author(s) Details Dr. R. Sumitra Department of Mathematics, Queen Mary’s College, Chennai-600004, Tamilnadu, India. Dr. V. Rhymend…

Estimation of Parameters of Certain Bivariate Distributions with Equal Coefficients of Variation by Concomitants of Order Statistics

For a sample of n pairs of observations from Bivariate normal distribution,Morgenstern type bivariate logistic distribution and morgenstern type bivariate exponential distribution , in which the marginal distributions of random variables X and Y have the same coefficient of variation c, we derive the best linear unbiased estimator of the parameters associated with the Y…

Recent Advancement on Analytical Solution for Linear and Nonlinear Systems of Partial Differential Equations Involving Time Conformable Fractional Derivatives

In this short chapter we apply the conformable fractional reduced differential transform (CFRDTM) method to compute solutions for systems of linear and nonlinear conformable fractional PDEs. The proposed method gives a numerical approximate solution in the form of an infnite series that converges to a closed form solution; which is in many cases the exact…

Multiscale Decomposition of Big Data Time Series for Analysis and Prediction of Macroeconomic Data: A Recent Approach

The problem of the extraction of the relevant information for pre- diction purposes in a Big Data time series context is tackled. This issue is especially crucial when the forecasting activity involves macroeconomic time series, i.e. when one is mostly interested in finding leading variables and, at the same time, avoiding overfitted model structures. Unfortunately,…

Generalized Riesz Systems and Ordered Structures of Their Constructing Operators

Theory of non-self-adjoint operators and these applications are interested in various felds of mathematics and physics. There are many research results related to pseudo-Hermitian operators. In this feld, generalized Riesz systems can be used to construct some physical operators. From this fact, it seems to be important to consider under what conditions biorthogonal sequences are…

An Approach of Second-order Duality for Nondifferentiable Multiobjective Programming Involving ( Φ, ρ)-Univexity

The concepts of ( Φ, ρ)invexity have been given by Carsiti, Ferrara and Stefanescu [1]. We consider a second-order dual model associated to a multiobjective programming problem involving support functions and a weak duality result is established under appropriate second-order ( Φ, ρ) univexity conditions. Author(s) Details Dr. Ganesh Kumar Thakur Department of Applied Sciences,…

A study on Equivalent Linearization Method with a Weighted Averaging for Solving Undamped Non-linear Oscillators

In this paper, the Equivalent Linearization Method (ELM) with a weighted averaging is applied to analyse five undamped oscillator systems with nonlinearities. The results obtained via this method are compared with the ones achieved by Parameterized Perturbation Method (PPM), Min-Max Approach (MMA), Variational Iteration Method (VIM), Homotopy Perturbation Method (HPM), Energy Balance Method (EBM), Hanormic…

Quantitative Analysis of Relationship between Three Psychological Parameters Based on Swallowtail Catastrophe Model: A recent perspectives

A sudden jump in the value of the state variable in a certain dynamical system can be studied through a catastrophe model. This paper presents an application of catastrophe model to solve a psychological problems. Since we will have three psychological aspects or parameters. Intelligence (I), Emotion (E), and Adversity (A), a Swallowtail catastrophe model …

Analysis of Probabilistic Distributions and Uncertainty of Information Flow at Administrative Workflows

Common methods found in the market such as LEAN, AGILE, SCRUM are short and insufficient to generate a high level of efficiency in discrete-continuous variables based workflows and aspects of classification, decidability and analysis remains mostly copies of successful cases. The new metric and theoretical framework proposed in this article allows qualitative classification and analysis…
