ON THE CO-EFFICIENT OF EXPANSION OF GAS SOLUTIONS [PDF]
Science, 1880 The dilatometers used in this research differ essentially from those generally employed in the measurement of the expansion of liquids. Their form is shown in the accompanying figure. The bulb (B) contained about 286 grms. of the liquid-[ at i 5?C = 286.3425 grms.] The dilatometer having been filled was placed in the bath in the position denoted in the

Two simple ways to find an efficient solution for a multiple objective linear programming problem
Buletinul Ştiinţific al Academiei Trupelor de Uscat, 2018 A number of methods and techniques for determining “effective” solutions for multiple objective linear programming problems (MPP) have been developed. In this study, we will present two simple methods for determining an efficient solution for a MPP that ...
