Generating Multi-objective Optimized Business Process Enactment Plans
Declarative business process (BP) models are increasingly
used allowing their users to specify what has to be done instead of how.
Due to their flexible nature, there are several enactment plans related to
a specific declarative model, each one presenting specific values for different
objective functions, e.g., completion time or profit. In this work, a
method for generating optimized BP enactment plans from declarative
specifications is proposed to optimize the performance of a process considering
multiple objectives. The plans can be used for different purposes,
e.g., providing recommendations. The proposed approach is validated
through an empirical evaluation based on a real-world case study.Ministerio de Ciencia e Innovación TIN2009-1371
Water waves generated by a moving bottom
Tsunamis are often generated by a moving sea bottom. This paper deals with
the case where the tsunami source is an earthquake. The linearized water-wave
equations are solved analytically for various sea bottom motions. Numerical
results based on the analytical solutions are shown for the free-surface
profiles, the horizontal and vertical velocities as well as the bottom
pressure.Comment: 41 pages, 13 figures. Accepted for publication in a book: "Tsunami

Dynamic response of Dam-Reservoir systems : review and a semi-analytical proposal
This paper presents a review of current techniques employed for dynamic analysis of concrete gravity dams under seismic action. Traditional procedures applied in design bureaus, such as the Pseudo-Static method, often neglect structural dynamic properties, as well as ground amplification effects. A practical alternative arises with the Pseudo-Dynamic method, which considers a simplified spectrum response in the fundamental mode. The authors propose a self-contained development and detailed examples of this latter method, including a comparison with finite element models using transient response of fluid-structure systems. It is verified that application of the traditional procedure should be done carefully and limited to extremely rigid dams. On the other hand, the proposed development is straightforward and in agreement with finite element results for general cases where dam flexibility plays an important role
