  • procedural simulation method for aggregating charging load model of private electric vehicle cluster
    Journal of Modern Power Systems and Clean Energy, 2015
    Co-Authors: Y U Jilai
    Abstract:

    The usage of each private electric vehicle (PrEV) is a repeating Behavior process composed by driving, parking, discharging and charging, in which PrEV shows obvious procedural characteristics. To analyze the procedural characteristics, this paper proposes a procedural simulation method. The method aggregates the Behavior process regularity of the PrEV cluster to model the cluster’s charging load. Firstly, the Basic Behavior process of each PrEV is constructed by referring the statistical datasets of the traditional private non-electric vehicles. Secondly, all the Basic processes are set as a simulation starting point, and they are dynamically reconstructed by several constraints. The simulation continues until the steady state of charge (SOC) distribution and Behavior regularity of the PrEV cluster are obtained. Lastly, based on the obtained SOC and Behavior regularity information, the PrEV cluster’s Behavior processes are simulated again to make the aggregating charging load model available. Examples for several scenarios show that the proposed method can improve the reliability of modeling by grasping the PrEV cluster’s procedural characteristics.

  • solubility and preferential solvation of sulfanilamide sulfamethizole and sulfapyridine in methanol water mixtures at 298 15 k
    Journal of Solution Chemistry, 2016
    Co-Authors: Zaira J Cardenas, Fleming Martinez, Abolghasem Jouyban, Daniel M Jimenez, Ovidio Almanza, William E Acree
    Abstract:

    The equilibrium solubilities of sulfanilamide, sulfamethizole and sulfapyridine in methanol + water mixtures at 298.15 K were determined and the preferential solvation parameters were derived from their thermodynamic solution properties by means of the inverse Kirkwood–Buff integrals. In all cases the drug solubility was the lowest in neat water and highest in neat methanol. The preferential solvation parameters for methanol (δx1,3) are negative in water-rich mixtures but positive in compositions from 0.32 in mole fraction of methanol to pure methanol. Based on these results it is conjecturable that in the former case hydrophobic hydration around the aromatic rings plays the main role in the drug’s solvation. The higher solvation by methanol in mixtures of similar cosolvent compositions and in methanol-rich mixtures can be explained in terms of the higher Basic Behavior of this co-solvent interacting with the Lewis acidic groups of the drugs. Besides, the drugs’ solubilities were mathematically represented by using the Jouyban–Acree model obtaining average percentage deviations lower than 2.6 % for correlative studies.

  • solubility and preferential solvation of sulfadiazine sulfamerazine and sulfamethazine in propylene glycol water mixtures at 298 15 k
    Journal of Molecular Liquids, 2015
    Co-Authors: Maria M Munoz, Abolghasem Jouyban, Daniel R Delgado, M A Pena, Fleming Martinez
    Abstract:

    Abstract The equilibrium solubility of sulfadiazine, sulfamerazine and sulfamethazine in propylene glycol (PG) + water binary mixtures was determined at 298.15 K and the preferential solvation parameters were derived from their thermodynamic solution properties by means of the inverse Kirkwood–Buff integrals method. It is found that these sulfonamides are sensitive to specific solvation effects. The preferential solvation parameters by PG ( δx 1,3 ) are negative in water-rich mixtures but positive in mixtures with compositions from 0.20 in mole fraction of PG to pure PG. It is conjecturable that in the former case the hydrophobic hydration around aromatic rings and/or methyl groups plays a relevant role in the solvation. The more solvation by PG in mixtures of similar co-solvent compositions and in PG-rich mixtures could be explained in terms of the bigger Basic Behavior of this co-solvent interacting with hydrogen-donor groups of the drugs.

  • solubility and solution thermodynamics of meloxicam in 1 4 dioxane and water mixtures
    Industrial & Engineering Chemistry Research, 2014
    Co-Authors: Daniel M Jimenez, Daniel R Delgado, Abolghasem Jouyban, Zaira J Cardenas, Fleming Martinez
    Abstract:

    The equilibrium solubility of meloxicam in 1,4-dioxane and water binary mixtures at temperatures from 293.15 to 313.15 K was determined, and the respective thermodynamic quantities of solution were calculated. Additionally, the preferential solvation parameters of the drug were derived from their thermodynamic solution properties by means of the inverse Kirkwood–Buff integrals method. From solvent effect studies, it is found that this drug is sensitive to specific solvation effects. The preferential solvation parameter by 1,4-dioxane, δx1,3, is negative in water-rich mixtures but positive in compositions in which 0.18 < x1 < 1.00. It could be possible that in water-rich mixtures the hydrophobic hydration around aromatic rings and/or methyl groups plays a relevant role in the drug solvation. The greater solvation by 1,4-dioxane in mixtures of similar cosolvent compositions and 1,4-dioxane-rich mixtures could be explained in terms of the greater Basic Behavior of the cosolvent interacting with the hydrogen-...
