The economic literature on “optimal income taxation” addresses the question of how to design tax and transfer policy so as to maximize “social welfare,” which is some function of the wellbeing of all members of society. It clarifies how the social-welfare-maximizing policy depends on one’s philosophy of distributive justice, and on empirical evidence about the behavioral response to incentives,...

Adequate shelter has always been one of man’s basic needs; it is a significant component for human survival and a useful barometer for gauging societal development. As a unit of the environment, it has a profound influence on the health, efficiency, social behavior, satisfaction, productivity, and general wellbeing of the individual and the entire community. However, one of the critical challen...

In this article, we investigate the measurement of performance in DMUs in which input and/or output values are given as imprecise data. By imprecise data, we mean that in some cases, we only know that the actual values are inside certain intervals, and in other cases, data are specified only as ordinal preference information. In this article, we present two distinct perspectives for determining...

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...

This study measures the efficiency of energy consumption in residential sector Slovenia. It extends existing research on estimation electricity by considering multiple sources used households. The detailed disaggregated data from two cross-sectional surveys conducted years 2010 and 2014, resulting a sample 6882 Slovenian households, is estimation. includes services stochastic frontier framework...

The present work evaluates the performance of solar collector using Al2O3-C2H6O2-H2O nanofluid as a working fluid through both experimental and CFD analysis. Ethylene-glycol water mixture (40:60 v/v) is used as base fluid, where α-Al2O3 nanoparticle of 20 nm average size is dispersed for the preparation of nanofluid of four different volumetric concentration (vol. conc.) of 0.05, 0.075, 0.1 and...
