Reuse is at the heart of major improvements in productivity and quality in Software Engineering. Both Model Driven Engineering (MDE) and Software Product Line Engineering (SPLE) are software development paradigms that promote reuse. Specifically, they promote systematic reuse and a departure from craftsmanship towards an industrialization of the software development process. MDE and SPLE have established their benefits separately. Their combination, here called Model Driven Product Line Engineering (MDPLE), gathers together the advantages of both. Nevertheless, this blending requires MDE to be recasted in SPLE terms. This has implications on both the core assets and the software development process. The challenges are twofold: (i) models become central core assets from which products are obtained and (ii) the software development process needs to cater for the changes that SPLE and MDE introduce. This dissertation proposes a solution to the first challenge following a feature oriented approach, with an emphasis on reuse and early detection of inconsistencies. The second part is dedicated to assembly processes, a clear example of the complexity MDPLE introduces in software development processes. This work advocates for a new discipline inside the general software development process, i.e., the Assembly Plan Management, which raises the abstraction level and increases reuse in such processes. Different case studies illustrate the presented ideas.

[ES]En los últimos años, la baja participación de la mujer y la tendencia al descenso de los porcentajes de alumnas matriculadas en los estudios universitarios de informática ha sido objeto de estudio para investigadoras/es en Estados Unidos, Europa y otros países. Habiendo constatado también en la Facultad de Informática de San Sebastián (FISS) de la Universidad del País Vasco (UPV/EHU) dicho descenso, nuestro objetivo ha sido recopilar información estadística para determinar si esta tendencia se ha producido también en otras universidades del Estado español. El estudio incluye, en primer lugar,porcentajes de mujeres inscritas en Ingeniería Informática comparados con los porcentajes en el área técnica en su conjunto. Por otra parte, recoge datos del tercer ciclo y porcentajes de profesoras de los departamentos que imparten docencia en la FISS, comparados con los porcentajes en los mismos departamentos en el conjunto del Estado. Por último, se presentan datos de inserción en el mundo laboral para las promociones 1998-2002 de egresadas/os en la UPV/EHU. Los datos revelan los bajos porcentajes de mujeres que se han matriculado en Ingeniería Informática los últimos años y la tendencia al descenso, las diferencias entre distintas universidades,y que apenas hay sesgo de género en los datos de inserción en el mundo laboral.

A partir del análisis del perfil del ingeniero en la sociedad europea, se ha elaborado una encuesta amplia mediante la que se solicitó a las empresas del entorno las competencias y materias que consideraban más importantes en la formación de los ingenieros de las titulaciones ofertadas en la Escuela. A partir de los resultados de dichas encuestas, se establece un perfil requerido a los titulados.

Through the coupling between aerodynamic and structural governing equations, a fully implicit multiblock aeroelastic solver was developed for transonic fluid/stricture interaction. The Navier-Stokes fluid equations are solved based on LU-SGS (lower-upper symmetric Gauss-Seidel) Time-marching subiteration scheme and HLLEW (Harten-Lax-van Leer-Einfeldt-Wada) spacing discretization scheme and the same subiteration formulation is applied directly to the structural equations of motion in generalized coordinates. Transfinite interpolation (TFI) is used for the grid deformation of blocks neighboring the flexible surfaces. The infinite plate spline (IPS) and the principal of virtual work are utilized for the data transformation between fluid and structure. The developed code was fort validated through the comparison of experimental and computational results for the AGARD 445.6 standard aeroelastic wing. In the subsonic and transonic range, the calculated flutter speeds and frequencies agree well with experimental data, however, in the supersonic range, the present calculation overpredicts the experimental flutter points similar to other computations. Then the flutter character of a complete aircraft configuration is analyzed through the calculation of the change of structural stiffness. Finally, the phenomenon of aileron buzz is simulated for the weakened model of a supersonic transport wing/body model at Mach numbers of 0.98 and l.05. The calculated unsteady flow shows, on the upper surface, the shock wave becomes stronger as the aileron deflects downward, and the flow behaves just contrary on the lower surface of the wing. Corresponding to general theoretical analysis, the flow instability referred to as aileron buzz is induced by a stronger shock alternately moving on the upper and lower surfaces of wing. For the rigid structural model, the flow is stable at all calculated Mach numbers as observed in experiment

[ES] El Castillo se encuentra coronando, junto a la iglesia de San Pedro, el cerro sobre el que se asienta el caserío de Cornago. Actualmente está formado por un patio interior de forma rectangular y rematado por cuatro torres en las esquinas, de las cuales tres son circulares de diferentes radios y una cuarta (NE) cuadrada, la superficie total ocupada es de unos 50 x 30 metros al exterior.

A lower-upper symmetric Gauss-Seidel (LU-SGS) subiteration scheme is constructed for time-marching of the fluid equations. The Harten-Lax-van Leer-Einfeldt-Wada (HLLEW) scheme is used for the spatial discretization. The same subiteration formulation is applied directly to the structural equations of motion in generalized coordinates. Through subiteration between the fluid and structural equations, a fully implicit aeroelastic solver is obtained for the numerical simulation of fluid/structure interaction. To improve the ability for application to complex configurations, a multiblock grid is used for the flow field calculation and transfinite interpolation (TFI) is employed for the adaptive moving grid deformation. The infinite plate spline (IPS) and the principal of virtual work are utilized for the data transformation between the fluid and structure. The developed code was first validated through the comparison of experimental and computational results for the AGARD 445.6 standard aeroelastic wing. Then, the flutter character of a tail wing with control surface was analyzed. Finally, flutter boundaries of a complex aircraft configuration were predicted.
