Therefore, it offers the coordination and optimization of the different power sources, with the result of a high energy saving and life extension of the systems.
University of Vigo posted this:New wheel slip reset controller for brake systemsThe main motivation for using reset control is the overcoming of fundamental limitations or trade-offs of conventional controllers: with the conventional controllers if we want a fast braking response, the system is fragile and sensitive to uncertainties; and if we want a robust system, this requires slower braking actions. Reset control is a novel technique that achieves more robust and fester braking responses in a way that no other conventional controller is able to produce.
University of Vigo posted this:New non-destructive method for “in situ” monitoring of anticorrosive protection of organic coatingsThe main novelty of the device and procedure is the new portable sensor adaptable to virtually any surface. The device, fixable by vacuum to the surface under study, makes possible the measurement of the electrochemical interfacial impedance, that is the main parameter of interest for adherence quality and anti-corrosion performance.
University of Vigo posted this:Lateral connection system by removable clamps for I or H profilesThe presented system allows detachable lateral connections, at right angles, type ‘cross beam to column flange’ of I and H standard profiles made of steel. The system uses standard mounting clamps without previous specific machining operations (as may be welding or drilling).
University of Vigo posted this:Removable system for continuous connection of square tube profilesThe removable system allows mounting on each profile separately, joining then in continuity with plates at the head of each of the flanges. The use of anti-buckling clamps prevents local buckling of the walls of the profiles, associated with tightening of flanges. Flanges have nerves to reduce stresses. The same flanges are valid for connecting different sized sections of square tube profiles.
University of Vigo posted this:Automated thickness measurement system for pantograph contact stripsUVIGO researchers have developed an accurate and reliable system for monitoring the durability of pantograph components preventing manual operator inspection. Based on artificial vision, this system measures the remaining thickness of the graphite layers of the collector strips. Automatic processing of collected data generates a 3D model of the strips, analyzing it to detect cracks and wear, which is crucial for pantograph maintenance.

Universidad de Alicante posted this:Method for recycling of vessels and other structures composed of fiberglass and resinResearchers at the University of Alicante have developed a method to recycle composite fiberglass structures on a polymer matrix (resin). The process removes the polymer matrix, recovering glass fiber which can be reused. The process is not aggressive with fiberglass. It takes place at room temperature and is able to recover all the fiberglass used. The method is industrially scalable and can be automated. Fiberglass composites and resin are widely used in the construction of boat hulls, tanks, wind turbine blades and many other applications. This method is a very important innovation for the sector and there was no effective method that allowed recovering and reusing these materials.
uacoopera posted this:Variable flow pump for longitudinal displacementA Portuguese University has developed an invention consisting of a new concept of flow variation in a vane pump that allows to bypass the concepts now patented and used. This invention therefore relates to a variable displacement vane pump and the variations in the fluid’s flow rate conveyed by the pump for a given rotation is achieved by changing a longitudinal length of the chambers, and not by changing the eccentricity between the ring and the rotor. This is the main difference between this and the variable flow vane pumps currently available. The university is looking for companies that develop and produce oil pumps to license this technology.

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.
DIT Hothouse posted this:iSeal: Advanced Surface Treatment for Protection against TribocorrosionThis invention is based on the application of a hybrid organic/inorganic treatment onto an exposed surface – either as a stand-alone treatment or as a sealant. The treatment is applied using an electrochemical deposition technique, allowing for the development of conformal coatings, irrespective of design complexity. Layer thicknesses are low (10-100nm) but resistance in corrosive marine environments indicate corrosion rates comparable to technologies currently employed by the aerospace and automotive industries. Corrosion rates are reduced by between 103 and 105 times, dependant on the nature of the porous coating. Tests on metallic coatings indicated a reduction in corrosion rates of approximately 103-104 while tests on ceramic coatings indicated a reduction in corrosion rates of approximately 105. By applying the hybrid treatment as a sealant treatment onto a porous wear resistant coating, concerns regarding the effect of mechanical damage are dramatically reduced. In addition, surface roughness levels are similar to electropolished finishes.
