  • knowledge supported Graphical Illustration of texts
    Advanced Visual Interfaces, 2002
    Co-Authors: Knut Hartmann, Stefan Schlechtweg, R Helbing, Th Strothotte
    Abstract:

    We introduce a new method to automatically and dynamically illustrate arbitrary texts from a predefined application domain. We demonstrate this method with two experimental systems (Text Illustrator and Agi3le) which are designed to illustrate anatomy textbooks. Both systems exploit a symbolic representation of the content of structured geometric models. In addition, the approach taken by the Agi3le-system is based on an ontology providing a formal representation of important concepts within the application domain as well as a thesaurus containing alternative linguistic and visual realizations for entities within the formal domain representation. The presented method is text-driven, i.e., an automated analysis of the morphologic, syntactic and semantic structures of noun phrases reveals the key concepts of a text portion to be illustrated. The specific relevance of entities within the formal representation is determined by a spreading activation approach. This allows to derive important parameters for a non-photorealistic rendering process: the selection of suitable geometric models, camera positions and presentation variables for individual geometric objects. Part-whole relations are considered to assign visual representations to elements of the formal domain representation. Presentation variables for objects in the 3D rendering are chosen to reflect the estimated relevance of their denotation. As a result, expressive non-photorealistic Illustrations which are focussed on the key concepts of individually selected text passages are generated automatically. Finally, we present methods to integrate user interaction within both media, the text and the computer-generated Illustration, in order to adjust the presentation to individual information seeking goals.

  • Poverty orderings: A Graphical Illustration
    Social Choice and Welfare, 2001
    Co-Authors: Buhong Zheng
    Abstract:

    This note Graphically illustrates the power of various poverty ordering conditions. Using the Kolm three-person simplex, we are able to show that (1) for a fixed poverty line the power may be increased as higher degrees of stochastic dominance are considered, (2) for a single but variable poverty line the power is reduced as the line increases, and (3) for a range of poverty lines the power of the third degree ordering condition may be reduced to that of the second degree if the lower bound poverty line is arbitrarily close to zero.

  • homogeneous heterogeneous reactions in peristaltic flow of prandtl fluid with thermal radiation
    Journal of Molecular Liquids, 2017
    Co-Authors: S Asghar, Tasawar Hayat, Anum Tanveer, Ahmed Alsaedi
    Abstract:

    Abstract This attempt is made to look at the influence of homogeneous–heterogeneous reactions on MHD peristaltic flow of Prandtl fluid. The configuration of channel is considered as inclined and asymmetric. Mathematical modelling is developed through consideration of Joule heating, viscous dissipation and thermal radiation. Heat and mass transfer phenomenons are addressed simultaneously. Numerical solutions of problem are attained after employing long wavelength and low Reynolds number assumptions. The results for velocity, temperature, concentration and heat transfer rate have been emphasized through Graphical Illustration. Physical interpretation for sundry parameters of interest is carried out in detail. Results indicate that concentration decreases during both homogeneous and heterogenous reactions where thermal radiation lessens fluid temperature and rate of heat transfer.

  • hall and ion slip effects on peristaltic flow and heat transfer analysis with ohmic heating
    Applied Mathematics and Mechanics-english Edition, 2014
    Co-Authors: Tasawar Hayat, S Asghar, Q Hussain, Fuad E Alsaadi
    Abstract:

    The peristaltic transport of a magnetohydrodynamic (MHD) fluid is examined for both symmetric and asymmetric channels. Hall and ion slip effects are taken into account. The heat transfer is analyzed by considering the effects of viscous and Ohmic dissipations. The relevant flow problems are first modeled, and then the closed form solutions are constructed under the assumptions of long wavelength and low Reynolds number. The solutions are analyzed through Graphical Illustration. It is noted that the velocity increases but the temperature decreases with the increases in the Hall and ion slip parameters. The axial pressure gradient is less in magnitude in the presence of Hall and ion slip currents. The Hall and ion slip effects are to decrease the maximum pressure against which peristalsis works as a pump. The free pumping flux decreases with the increases in the Hall and ion slip parameters. The increases in the Hall and ion slip parameters result in an increase in the size of the trapped bolus.
