This work is devoted to present a scalable domain decomposition method to solve nonlinear elastodynamic problems. Large non linear elastodynamic problems represent an appropriate application field for substructuring methods which are efficient on parallel computer with the proviso of using specific preconditioner techniques well adapted to the mechanical modeling. According to this reason, we d...

Perrin et al. (1995) and Geubelle and Rice (1995) have introduced a spectral method for numerical solution of twoand three-dimensional elastodynamic fracture problems. The method applies for ruptures confined to a plane separating homogeneous elastic half spaces. In this method, the physical variables, such as the traction components of stress and displacement discontinuity on the rupture plane...

Frugal innovation (FI), which has gained traction in various sectors, is loosely defined as developing quality solutions a resource-constrained environment that are affordable to low-income consumers. However, with its popularity, multiple and diverse definitions have emerged often lack theoretical foundation. This led convoluted conceptualisation hinders research adoption practice. Despite thi...

To study the short-term uptake of potassium across the basolateral membrane into individual tubule cells, rubidium was used and measured by electron microprobe analysis. Changes of rubidium uptake were interpreted to reflect altered sodium entry and basolateral Na-K-ATPase activity. The effects of hydrochlorothiazide, amiloride and furosemide were determined in saline-loaded animals. Hydrochlor...

The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis. Recent genetic and physiologic studies have greatly expanded our understanding of how the distal convoluted tubule regulates these processes at the molecular l...

The Inversion Problem Our standard modeling and control concepts and techniques include linear convolution models and various transform techniques (the Laplace transform, the Z-transform, the bilateral Laplace transform, the bilateral Z-transform, the continuous Fourier transform, and the discrete Fourier transform). In fact, these techniques form the basis of the broad areas of circuits, commu...

Elastodynamic problems are investigated in this work by employing the enriched finite element method (EFEM) with various enrichment functions. By performing dispersion analysis, it is confirmed that for elastodynamic amount of numerical dispersion, which closely related to error from space domain discretization, can be suppressed a very low level when quadric polynomial bases employed construct...
