24 p, 294.5 KB A statistical learning based approach for parameter fine-tuning of metaheuristics / Calvet, Laura (Universitat Oberta de Catalunya) ; Juan, Ángel A., dir. (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Serrat, Carles (Universitat Politècnica de Catalunya.

Metaheuristics are approximation methods used to solve combinatorial optimization problems. Their performance usually depends on a set of parameters that need to be adjusted. The selectionof appropriate parameter values causes a loss of efficiency, as it requires time, and advanced analytical and problem-specific skills. [...]

Coherent control of regions with spatial excitation of populations and coherence between two lower states in three-level Λ-type quantum systems mediated by the self-induced transparency (SIT) phenomenon is theoretically investigated with one- and two-color ultrashort pulses and with pulse sequences beyond the slowly varying envelope (SVEA) and rotating wave (RWA) approximations.

22 p, 257.1 KB Nonparametric bivariate estimation for successive survival times / Serrat, Carles (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada I) ; Gómez Melis, Guadalupe (Universitat Politècnica de Catalunya. Departament de Estadística)
Several aspects of the analysis of two successive survival times are considered. All the analyses take into account the dependent censoring on the second time induced by the first. Three nonparametric methods are described, implemented and applied to the data coming from a multicentre clinical trial for HIV-infected patients. [...]
