This note provides some examples of plant leaves whose outline maps exhibit Poincaré recurrence and mixing while subjected to repeated Anosov diffeomorphic transformation. The datasets and a computer program (Fortran 77) have also been given

This paper proposes a method to construct composite index, which is a linear combination of several variables, by deriving weights on the criterion of Shapley value (from cooperative game theory) that a constituent variable has in making the composite index. In practice it is found oftentimes...

The entire education system of Bihar, starting from primary education to higher learning is plagued by corruption, inefficiency and disregard for quality. Although the Bihari youths have wonderful brains and amazing power of perseverance and tenacity to pursue and achieve their goals, Bihar is...

This paper aims at locating the practice of micro-credit system into a larger theoretical canvas of economic theory and philosophy. A systems theoretic approach has been adopted. Emergence of the ‘excluded' class has been explained with the help of the theory of feedback. Individuals have been...

This study builds a simultaneous equation model that establishes inter-connections among the measures of globalization, measures of democracy, human development, corruption perception index and per capita income, which in turn jointly influence social progress. The model has eleven equations in...

In this study we build a simultaneous equation model in which the measures of different aspects of globalization (attributable to KOF) and different aspects of democracy (attributable to EIU) are related in seven structural equations. A bi-directional relationship between democracy and...

The Two-Stage Least squares method for obtaining the estimated structural coefficients of a simultaneous linear equations model is a celebrated method that uses OLS at the first stage for estimating the reduced form coefficients and obtaining the expected values in the arrays of current...

Correlation matrices have many applications, particularly in marketing and financial economics - such as in risk management, option pricing and to forecast demand for a group of products in order to realize savings by properly managing inventories, etc.Various methods have been proposed by...

In the extant literature a suggestion has been made to solve the nearest correlation matrix problem by a modified von Neumann approximation. In this paper it has been shown that obtaining the nearest positive semi-definite matrix from a given non-positive-semi-definite correlation matrix by such...

Particle swarm optimization and Differential Evolution (DE) optimization methods of global optimization are two of the very versatile methods of minimization/maximization of multimodal non-convex continuous nonlinear functions that find their application in many fields of engineering, natural...
