it is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. quantitative structure – activity relationship (qsar) studies and quantitative structure –property relationship (qspr) studies are active areas of chemical research that focus on the nature ofthis dependency. topological indices are the numerical value associated with chemical constitution...

This paper seeks to uncover dominant configurations of inter-organizational relationships across the USA and Japan in the automotive industry. We integrate relevant theoretical concepts from transaction cost economics, organization theory and political economy to develop a conceptual model of inter-organizational relationships based on the fit between information processing needs and informatio...

We present a novel synthesis algorithm for procedurally generating complex curves. Our approach takes a simple example input curve specified by a user and automatically generates complex curves that resemble the input. The algorithm preserves many of the input shape features such as tangent directions, curvature, branch nodes, and closed loops. The overall approach is simple and can be used to ...

Miguel, Department of Physics, School of Sciences and Technology, University of Évora, Rua Romao Ramalho 59, 7000-671 Évora, Portugal e-mail: [email protected] The occurrence of configuration (design, shape, structure, rhythm) is a universal phenomenon that occurs in every flow system. Dendritic configuration (or tree-shaped configurations) is ubiquitous in nature and li...

The DO1(18c6)fi (MwLi. Na. K and I 8c6=18-crown-6) complexes have been chosen as the model systems toinvestigate the nature of chemical bonds between alkali metal cations and large mffitidentaie orgmnic ligands.The B3LYP/6-3I+G(d,p) level of calculation has been used for obtaining equilibrium geernetnes and p(r)functions (electron density distributions). By the aid of fundamental physical theor...
