Determination of TL parameters of CaSO4: Dy produced at Instituto de Pesquisas energéticas e nucleares (IPEN)
Abstract Two important parameters to be determined in a thermoluminescence study are the frequency factor ( s ) and the trap depth ( E ). The E and s determinations are based on glow curve analysis. Results of experiments made with CaSO 4 :Dy prepared in the Dosimetric Materials Production Laboratory of Instituto de Pesquisas Energeticas e Nucleares (IPEN) are presented in this paper.
For soft soils time-dependent consolidation processes are highly non-linear and require adistinct analysis of the overlying mechanisms. In the present study thus an analytical, rigoroussolution for one-dimensional consolidation of a clay deposit with permeable top andimpermeable bottom under haversine cyclic loading with restperiod is introduced. The solutionwas achieved using Fourier harmonic analysis for the periodic function representingthe rate of imposition of excess pore water pressure. Comparing the derived solution to asolution by Razouki & Schanz (2011) using an implicite finite difference technique andavailable solutions in literature, advantages are illuminated. Additionally, the presented,analytical solution is used to validate a numerical solution of the same conditional problemvia finite element method.
