The linear and nonlinear optical (NLO) properties of a series ?-shaped derivatives containing 4,5-dicyanopyrazine acceptor unit, N,N-dimethylamino donor groups systematically enlarged ?-conjugated linkers are investigated by means UV/Visible Hyper-Rayleigh scattering spectroscopies. Density functional theory calculations also carried out to rationalize the magnitude symmetry NLO responses. resu...

This paper presents the optimization of vibrations of centrifugal pump considering fluid-structure interaction (FSI). A set of centrifugal pumps with various blade shapes were studied using FSI method, in order to investigate the transient vibration performance. The Kriging model, based on the results of the FSI simulations, was established to approximate the relationship between the geometrica...

We present this paper in order to suggest a new tool for political science in respect to identifying unstable countries and their root indicators that could suggest areas for political intervention. With more than 98% accuracy, we were able to predict severely unstable political states based on countries with a Fragile States Index (FSI) score of > 100. In addition, we were able to determine th...

Poverty reduction and sustainability are the two major issues in achieving sustainable development. Microfinance emerged as an essential catalyst for socioeconomic development financial inclusion to reduce poverty. MFIs cannot meet their primary objective of poverty if they not financially. With theoretical support Profit Incentive theory, this paper examines microfinance providers (MFPs) Bangl...

A distribution space is called finitely shift invariant (FSI) if it is generated by a vector-valued distribution (generator) and its shifts. The linear independence of shifts of a generator is important in many applications. This paper provides a characterization for linear independence of the shifts of a generator of an FSI distribution space and presents a way to find the generators with line...
