And Control

Overtopping-type wave power conversion devices represent one of the most promising technology to combine reliability and competitively priced electricity supplies from waves. While satisfactory hydraulic and structural performance have been achieved, the selection of the hydraulic turbines and their regulation is a complex process due to the very low head and a variable flow rate in the overtopping breakwater set-ups. Based on the experience acquired on the first Overtopping BReakwater for Energy Conversion (OBREC) prototype, operating since 2016, an activity has been carried out to select the most appropriate turbine dimension and control strategy for such applications. An example of this multivariable approach is provided and illustrated through a case study in the San Antonio Port, along the central coast of Chile. In this site the deployment of a breakwater equipped with OBREC modules is specifically investigated. Axial-flow turbines of different runner diameter are compared, proposing the optimal ramp height and turbine control strategy for maximizing system energy production. The energy production ranges from 20.5 MWh/y for the smallest runner diameter to a maximum of 34.8 MWh/y for the largest runner diameter.

Estudio De Caso

ABSTRACTThe social networking phenomenon starts generating various investigations, but so far none has raised the relationships among users of a social network from the behavioral and psychological point of view. To this end, we have conducted an empirical study based on simulated profiles in Facebook, relevant social network due to the amount of available users and for its IPO. From imaginary profiles, we analyze the types of other Facebook users that are added, which can inspire ecommerce strategies related to digital newspapers.RESUMENEl fenómeno de las redes sociales comienza a generar investigaciones diversas, pero de momento ninguna ha planteado las relaciones entre los usuarios de una red social desde el punto de vista conductual y psicológico. A tal efecto, hemos llevado a cabo un estudio empírico a partir de una simulación de perfiles en Facebook, red social de referencia por la cantidad de usuarios disponibles y por su salida a bolsa. A partir de perfiles imaginarios, analizamos la tipología de otros usuarios de Facebook que se le agregan, lo que puede inspirar estrategias de comercio electrónico vinculadas a los periódicos digitales.
