1. The use of the perturbative methods for the sensi-tivity analysis in hyperthermic problems caused by the laser sources in the treatment of tumors / Uso de métodos perturbativos para análise de sensibi-lidade em problemas de hipertermia causada por fontes de laser usadas no tratamento de tumores
The hyperthermic procedures available for therapeutic treatments of tumors can cause thermal damage in the adjacent living tissues and it is necessary to have an effective control systems. The temperature distribution inside the tissue must be controlled in order to avoid thermal damages to the healthy tissues in the neighborhood of the tumor. Numeri-cal sim

2. AnÃlise de sensibilidade de 2Â ordem numa cÃlula a combustÃvel tipo PEM
No atual estÃgio de desenvolvimento em que a humanidade se encontra, a demanda por energia elÃtrica cresce drasticamente a cada ano. Entretanto, a provÃvel escassez da matriz energÃtica de base fÃssil, associada aos danos ecolÃgicos ocasionados pela sua prospecÃÃo e utilizaÃÃo, tem despertado o interesse por novas formas alternativas e renovÃveis

3. Sensitivity analysis of shallow water problems via perturbative methods
We applied the perturbative theory to perform sensitivity analysis of the shallow water equations. The numerical solution of these equations was found via the mass lumping finite element technique. Then, the adjoint system of the shallow water equations was derived for the one-dimensional case and the expression of the sensitivity coefficient of a generic fu

4. Sensitivity computations using first and second orders perturbative methods for the advection-diffusion-reaction model of pollutant transport
This work aims to apply the disturbance theory to accomplish sensitivity computations in problems of pollutant transported in liquid media modeled through the advection-diffusion-reaction equation. The numerical solution of the differential equation that describes the behavior of the system was found via the SUPG ("Streamline Unwinding Petrov Galerkin") fini
