A Model of Culturally-Diverse Patterns of Communication for Meaningful Learning

Teachers who address culturally-diverse classrooms using their own cultural ‘communication modes’ promote ‘communication dysfunctions’ which diminish the classrooms’ production of meaningful learning. A proposed interaction model of culturally-diverse patterns of communication supplies ‘cultural congruency’ at all levels of communication between teachers and students. The Model proposes that teachers address the culturally-diverse classrooms in as many diverse communication modes as culturally-diverse are the students. The Model was created as a response to the unsatisfactory Meaningful Learning efficiency of a traditional one-cultured-teacher, teaching to a Multicultural classroom.

Development of a Coupling Model for Fluid-Structure Interaction using the Mesh-free Finite Element Method and the Lattice Boltzmann Method

In the presented thesis work, the meshfree method with distance fields was coupled with the lattice Boltzmann method to obtain solutions of fluid-structure interaction problems. The thesis work involved development and implementation of numerical algorithms, data structure, and software. Numerical and computational properties of the coupling algorithm combining the meshfree method with distance fields and the lattice Boltzmann method were investigated. Convergence and accuracy of the methodology was validated by analytical solutions. The research was focused on fluid-structure interaction solutions in complex, mesh-resistant domains as both the lattice Boltzmann method and the meshfree method with distance fields are particularly adept in these situations. Furthermore, the fluid solution provided by the lattice Boltzmann method is massively scalable, allowing extensive use of cutting edge parallel computing resources to accelerate this phase of the solution process. The meshfree method with distance fields allows for exact satisfaction of boundary conditions making it possible to exactly capture the effects of the fluid field on the solid structure.
