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:Diagnosis and cleaning using laser technology for the restoration of historical monumentsSince ancient times granite has been used in historic buildings. Some restorers used to apply molten beeswax on their granite surfaces to stop imminent deterioration of the monuments. At first, this treatment was a good solution to consolidate the stone, but with time it resulted counterproductive. This method allows removal and cleaning of wax and other contaminants from porous stones in historical monuments and artworks using nondestructive means through laser technology.

The algorithm couples 1D mechanical modelling with 2D simulation of cross-section temperature distribution what makes it very efficient. The application consists of GUI and stimulation engine modules.
Consejo Superior de Investigaciones Científicas posted this:Thermochromic mortar coating for a more sustainable construction CSIC has developed a thermochromic mortar coating with optical properties in the solar radiation range that vary according to temperature in a reversible way. The mortar is especially interesting for energy efficiency in buildings. Its solar radiation absorption at low temperatures is high, helping to maintain indoor heating, while its reflectance increases during the summer, reducing over-warming of the envelope. Industrial partners from the construction industry are being sought to collaborate through a patent licence agreement.
Cracow University of Technology posted this:Comprehensive method to assess the technical condition of the pressure equipment of installation operated in the chemical and petrochemical industryA comprehensive method to assess the technical condition of the pressure equipment of installation operated in the chemical and petrochemical industry, with the use of acoustic emission signal analysis, structure stress field and the degradation st The algorithm for the assessment of the technical condition of pressure equipment of chemical and petrochemical installations, subjected to the long-term operation, allows to determine the damage degree of the material and allows to predict the further development of degradation processes in a function of time. The proposed approach to the problem of safe operation of devices is fundamentally different from the solutions which are currently used in industrial practice. Currently, the supervision of these objects is based mainly on standard non-destructive testing methods. The main limitation of used methods is the lack of the possibility of both examining the object in its entire volume and testing the device in working conditions. Developed algorithm allows to effectively solve current problems in the diagnosis of chemical installations related to the assessment of their technical condition and determination of the conditions for further operation in real time. The algorithm is particularly recommended for monitoring devices in which adverse damages occur due to the long-term operation.
Universidad de Alcalá-OTRI posted this:Artificial vision system for the semaphoric control of the access to parking and garages, through the monitoring of pedestrians.The research group “Intelligent Vehicles and Traffic Technologies” of the Automation Department of the University of Alcalá has developed a procedure for the semaphoric control of the access roads to parkings and garages by monitoring pedestrians using artificial vision. It is a road safety system that ensures that the exit access of the vehicles from the parking is performed safely for pedestrians, by monitoring the different access points to the parking, using a stereoscopic vision system with infrared lighting. The images provided by the stereoscopic vision system are processed by a computer, obtaining information regarding the presence of pedestrians in the vicinity of the monitored access point. This information is used to act on a traffic light that controls the exit access of vehicles. The group looks for licensing agreements, technical cooperation agreements, manufacturing agreements or commercial agreements with technical assistance, with companies from the sector of transport infrastructure and traffic safety.
Universidad de Alicante posted this:System for fixing armours during concretingThe research group “Materials and Construction Systems for Buildings”, from the Building and Urbanism Department of the University of Alicante, has developed a new and simple system that allows to fix any type of armours in concrete construction elements during the concreting process. This system avoids the movement of the armours in an efficient, technical and reusable way, and, therefore, also avoids future expensive treatments in case of unwanted movements. This new system is characterized by its low cost, light weight, ease of use and versatility for any constructive element. The research group is looking for companies interested in commercial exploitation.
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 and reconfigurable system for corner connection of square tube profilesThis removable connection system can be adapted to the size of the section, by adjusting the length of the connecting bolts, using the same flanges. Is usable for a wide range of standard profiles, which avoids the need for a flange size for each profile section.
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.
Universidad de Alcalá-OTRI posted this:Diagnosis of the Building Pathologies by qualified and quantified images.The research group "Image, Metrics and Architecture" from the University of Alcalá along with the startup Voar has developed the tool for the diagnosis of pathologies in the construction by the images processing. The images are captured with digital, thermal imagers, with the use of drones and robots to enter to areas with difficult access and from them, the processing that facilitates the diagnosis is carried out with a software. This tool is useful for conservation and maintenance companies of buildings, real estate corporations, insurance companies or certification to achieve collaboration and commercial agreements with technical assistance.

It also allows dynamic strain measurements completing a full strain measurement per second in each of the 50000 measurement points.
