Cracow University of Technology posted this:A propulsion/drive system of aquatic vessels.Both proposed side fins drive systems have similar features which are realized by slightly different mechanisms dependant on the room inside vehicles hull. Those features are as follows: - multi-functionality, - ability to generate an extra driving force, - significant increase of swimming speed, - reduction of robot unwanted hull movements during swimming with side fins enabling proper work of onboard equipment and sensors etc. (for solutions in robots imitating fish); - increasing the dynamic of swimming depth changes; - wide range of change of direction of thrust force (also reverse thrust). - unlimited range of change of thrust around axis of rotation of side fins, - ability to dynamically stabilize heel movement of the hull - no change in the direction of rotation of the main engine transferred into oscillatory motion of lateral fins, - less energy consumption, - frequency of oscillation at a level of several Hz
University of Vigo posted this:Suppression of Impulsive Noise for Power Line CommunicationsPower Line Communications (PLC) is an emerging field that enables to carry data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The widespread use of these technologies is however, compromised by the presence of impulsive noise that arises from interferences generated by devices connected to the power line. Therefore removal of impulsive noise is critical to get a high performance of PLC systems. UVIGO researchers have developed a novel methodology to mitigate impulsive noise by monitoring those carriers of the radiofrequency spectrum that are free of transmission in PLC systems. The identification of the noise signals allows its selective removal keeping the quality of the overall PLC signal.

DIT Hothouse posted this:UPQC: A Device for Power Quality EnhancementUPQC (Universal Power Quality Conditioner) allows optimal control of a power electronics-based conditioner. Comprising both shunt and series elements (inverters), UPQC compensates for sags and swells, unbalance and distortion (harmonics)in the supply current and supply voltage respectively. UPQC delivers cost savings, increased reliability and enhanced electrical power network functionality. It also employs modular control software and novel techniques for load side short circuit protection of series inverters.

Universidad de Alcalá-OTRI posted this:Capacity control and people counting system.GEINTRA, a research group from the department of electronics of the University of Alcala, offers a technological solution for people counting allowing an accurately real-time people counting. The system can count the exact number of people accessing a particular enclosure (building, shopping malls, nightclubs, etc.) which allows to take appropriate actions based on the number of people who are inside the controlled room (it informs to the authorities of the number of people, it can be used for the ventilation activation adapted to the needs, restricted access, etc.). GEINTRA is looking for companies working in technological or telecommunications sectors to achieve cooperation or license agreements.

Fundació URV posted this:New optical sensor, system and method of detecting ice on a surfaceThe optical sensor, size of few millimetres, should be flush mounted in surfaces as the wings and flaps of an airplane, wind turbines, cooling chambers, and other surfaces. The sensor is be able to detect ice appearing in early stages of nucleation with micrometric sensitivity on any surface. The sensor allows the generation of an ice map if sensors are installed in array.
Universitat de València posted this:HyLED optospintronics devicesThe most innovative aspect of this innovation is that provides new optospintronic devices with low emission threshold voltages. Also, the new devices have the following advantages: Efficiency: light emission threshold voltages from 2 V. Stability: use of air-stable electrodes, with high work function. Spin valve properties (magnetoresistance): control of electrical properties by means of magnetic fields, for example light intensity and colour. Low cost: manufacture with commercial and readily available materials, using soluble deposition methods, much cheaper, and viable on a large scale, that evaporative deposition methods.
Universitat de València posted this:Nanocomposites for electrochemical supercapacitorsThe new materials have the following advantages over existing materials in supercapacitor’s sector: Supercapacitive properties: they have specific capacitance values much higher than those obtained by commercial nanostructured carbon electrodes. Low cost: obtained by a chemical process of a single stage, with a single precursor, at low temperature, and highly available, non-polluting and low cost materials. Good cyclability: testing in cyclability is promising in terms of electrochemical and mechanical stability. In parallel to its advantages as supercapacitors, the nanocomposites show the advantages associated with the following additional properties: Giant magnetoresistance, GMR: this property is observed at room temperature, and high magnetic fields are not needed. Source of carbon nanoforms: based on the nanocomposite, can be obtained a mixture of carbon nanoforms consisting of nano-onions and multi-walled nanotubes.
Universitat de València posted this:New method for the production of metallic oxides with spinel structureThis procedure is faster, with lower energy consumption and generates purer spinels than known methods for spinel production. With this invention, it’s possible to provide new methods for obtaining spinels or other mixed oxides with a higher processability and versatility than those existing to date, allowing also for obtaining new spinels and removing the need for extremely costly phases in time or energy, including milling or heating at temperatures up to 1200ºC.
