The object of ehis study is the process of assessing welfare of the economic entities system. The subject of the study is the instrumental and mathematical aspects of modeling and measuring the public welfare. The aim of the work is ...

In this paper, we introduce a novel multi-period data envelopment analysis (MDEA) model that attempts to circumvent the limitations of existing MDEA models. The proposed global is essentially based on major modifications fundamental DEA axioms enable decision making unit (DMU), defined with inputs and outputs period t , be evaluated within production possibility set (PPS) another l ≠ l. Buildin...

The utility scale of non-conventional generators (NCGs), such as wind and photovoltaic (PV) plants, are competitive alternatives to synchronous machines (SMs) for power generation. Higher penetration NCGs has been respondent causing several recent incidents leading up voltage collapse in systems due the distinct characteristics under different operating conditions. Consequently, so-called syste...

This paper constructs a global economic policy uncertainty index through the principal component analysis of indices for twenty primary economies around world. We find that PCA-based is good proxy on scale, which quite consistent with GDP-weighted index. The found to be positively related volatility and correlation financial market, indicates stock markets are more volatile correlated when high...

BACKGROUND Left ventricular myocardial performance index is a Doppler-derived parameter of nongeometrical ventricular function that measures both systolic and diastolic function of the left ventricle. The objective of this study was to compare prognostic value of left ventricular myocardial performance index with global left ventricle function in patients undergoing coronary artery bypass graft...

The global Multidimensional Poverty Index, published annually since 2010, captures acute multidimensional poverty in the developing world. In 2018, five of its ten indicators were revised with purpose aligning index to Sustainable Development Goals (SDGs) insofar as current data permit. This paper provides comprehensive analyses consequences this revision from three perspectives. First, we thor...
