This paper is concerned with using linear features in aerial triangulation. Without loss of generality, the focus is on straight lines with the attempt to treat tie lines in the same fashion as tie points. The parameters of tie lines appear in the block adjustment like the tie points do. This requires a unique representation of lines in object space. We propose a four-parameter representation t...

the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

Ternary phase equilibrium data for ethanol-water-1-hexanoic acid and 1-nonanoic were experimentally obtained with a view to evaluate the possibility of separation ethanol from aqueous solutions by distributing each between water phases. The mutual solubility curves, tie lines plait points constructed experimental results. Distribution coefficients factors computed these systems. Hand’s method w...

We present a new and efficient methodology for the explicit representation of thermodynamic phase behavior associated with multicomponent two-phase flow in porous media. The method is based on interpolation in the discretized tie-line (Γ) space. Since a large number of supporting points may be required needed for direct discretization of the Γ−space, the discretization is performed adaptively d...

liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 k. the studied systems exhibit two types of liquid-liquid equilibrium (lle) behavior. the system consisting of benzyl alcohol displays type-1 lle behavior, while a type-2 behavior is exhibited by the other s...

Liquid-Liquid equilibrium data for the (water + Lactic acid + 2-ethy-1-hexanol) ternary system in T=298.2K and P=1atm were determined and tie- lines related to equilibrium data has been drawn in the phases diagram . The reliability of the experimental tie-line data for this system was as confirmed by using the Hand and Othmer –Tobias correlations. The tie-line data were correlated by means of t...

Deuterium quadrupole NMR line shapes were simulated to match experimental spectra of liquid crystalline phases observed in the cesium and sodium n-tetradecanoate-Dz0 systems. The line shapes of single-phase samples with both uniaxial and biaxial symmetry were accurately simulated. Line shape simulations were matched to experimental spectra by minimizing the sum of squared residuals on the basis...
