Formulação p. adaptativa do método dos elementos de contorno aplicado a problemas de potencial
… concerned with the development of the p-adaptive version of the boundary element method applied to bidimensional steady state potential problems. In the p version of automatic refinement, hierarquical shape functions are selectively inserted in the discretization, complying with error analysis. …

Optimization of Plane Wave Directions in Plane Wave Discontinuous Galerkin Methods for the Helmholtz Equation
… to provide an a priori error analysis of its p-version with respect to equidistributed plane wave directions. However, the dependence on the distribution of the plane wave directions has not been studied. In this thesis, we study the dependence by formulating the choice of the directions as an …

Worker's perception regarding the introduction of technology at Chiadzwa diamonds mines in Zimbabwe
… Statistica! Package for Social Sciences ( P ) version 19.0 was used to carry out data analysis. The Mann Whitney U test was used to test for th significance of differences in the perceptions of skilled and unskilled workers. No statitically significant differences were detected between skilled …

Modeling and control of flexible structures
… Refining the elements using the hierarchical p-version proves to be far superior to refining the mesh, as demonstrated by numerical examples. In the third chapter, a method is presented for solving the algebraic eigenvalue problem for a structure, which combines attractive features of the …

Development and Applications of Finite Elements in Time Domain
… Also the formulation, used in the h-, p- and hp-versions, is extended and found to be readily amenable to multi-degree-of-freedom systems. The resulting linear and nonlinear algebraic equations for the transient response are differentiated to obtain the sensitivity of the response with respect to …
