Abstract: The present invention allows increasing the net electric power supplied to the network by the solar thermal power plants of the cylindrical parabolic collector type by using the solar field in a more efficient manner, generating steam to drive the main ancillaries by means of steam turbines (turbo pumps), reducing electric consumption of the ancillary services and therefore increasing the net electric power of the plant. On days when the solar radiation is greater than the designed radiation, part of the solar field must stop being used since the generator and the turbine would exceed its designated power. The present system proposes harnessing the unused portion of the solar field for generating steam to drive the main ancillaries of the plant, energy which would otherwise not be harnessed. In addition, the overall operating performance of the ancillary service pumps is better when using steam to drive the pumps through a steam turbine (turbo pumps) instead of driving them with electric motors (motor pumps).

Abstract: A continuous query parallel engine on data streams provides scalability and increases the throughput by the addition of new nodes. The parallel processing can be applied to data stream processing and complex events processing. The continuous query parallel engine receives the query to be deployed and splits the original query into subqueries, obtaining at least one subquery; each subquery is executed in at least in one node. Tuples produced by each operator of each subquery are labeled with timestamps. A load balancer is interposed at the output of each node that executes each one of the instances of the source subquery and an input merger is interposed in each node that executes each one of the instances of a destination subquery. After checks are performed, further load balancers or input managers may be added.

Abstract: Underwater electrical energy generator with a three-blade propeller for the harnessing of energy from the water in the direction of its axis, in both directions. The propeller drives an alternating current generator located in a central dome from which there extend three arms joined to floats which close the Y-shaped structure by means of tie beams. The assembly has neutral floatability and is set into position by means of an anchoring system with a set of buoys joined to the bottom by one or more cables. An end of the generator is joined to an anchoring line by means of a horizontal cable in one of the main directions of the current. From the other end another two horizontal cables, open at an angle with respect to the direction of the current, are joined to another two anchoring lines. The assembly can be ballasted to go from an operating vertical underwater position to a horizontal floating position to facilitate maintenance tasks.

The polycrystalline material is disintegrated again by means of mechanical processes in the form of a powder and is then compacted, through the application of a suitable pressure in order to form a target.

Abstract: A method and device capable of evaluating the specific values of the polarization state of the signal transmitted in a photonic transmission system for a number of frequencies of one or more of the pulses extracted from the optical signal by means of the translation of the frequential components of polarization state of one or more pulses to the time domain by means of the use of an optical Fourier transformer, and their sampling, quantification and subsequent analysis.

This information may be used as a control signal for a PMD compensator device in order to upgrade the quality of communication in the system.

Abstract: It is a drip cap which works as a passive, eco-efficient and sustainable system to optimize and harness architectural resources, through the adaptation of inclined plane slopes, replacing their function of drip caps and turning them into surfaces which reflect undesired direct solar radiation, so that they contribute to low power consumption during warm months in massive building. It shields the interior from solar incidence and reduces energy flow through the enclosure openings, reducing heat gain, accumulation and penetrations by conduction and reflected radiation, suppressing a traditional heat bridge.

Abstract: The invention relates to the use, in the manufacturing of materials or devices for photonic applications, of chalcogenide-type compounds having an octahedrally coordinated indium element and wherein a transition element is introduced in octahedral position generating a partially occupied intermediate band separate from those of valence and conduction of the initial semiconductor, according to quantum mechanics calculations. This enables, by absorption of two photons having energy lower than the prohibited bandwidth of the initial semiconductor, a result equivalent to that achieved, without said intermediate band, by the absorption of a higher-energy photon. The use of such a material can thereby improve yield and performance of various photovoltaic, photocatalytic, photoelectrochemical, optoelectronic or photonic conversion devices. Indium sulfide substituted in part with vanadium or titanium is one of the specific materials having these properties that is synthesised according to the invention.
