Error estimation and h-adaptive refinement in the analysis of natural frequencies
(ELSEVIER SCIENCE BV, 2001-12-01)
This paper deals with the estimation of the discretization error and the definition of an optimum h-adaptive process in the finite element analysis of natural frequencies and modes. Consistent and lumped mass matrices are ...
A photogrammetric method for single image orientation and measurement
(2005-06-01)
The aim of this paper is to present a photogrammetric method for determining the dimensions of flat surfaces, such as billboards, based on a single digital image. A mathematical model was adapted to generate linear equations ...
