Solar driven absorption cycle for space heating and cooling The invention relates to a new solar thermally driven system that meets the heating and cooling demands of buildings. The system consists of a reversible absorption cycle which operates as a single effect absorption cycle in the cooling mode and as a heat transformer in the heating mode. Components of both cycles are the same, only the flow direction inside the system changes. In thermally driven systems, solar thermal collectors convert solar energy into thermal heat which can be used to run a thermally-activated device. Different types of thermally driven systems are available on the market, but among them, absorption systems are the most mature technology and are commercially available. The thermal collectors mostly used in solar absorption installations are flat plate or evacuated tubes. These thermal collectors produce hot water to drive the absorption machine in summer and produce chilled water. However, the hot water temperature obtained in winter with these solar collectors is too low to directly feed conventional heating systems but also is too low to drive the absorption machine in order to produce a higher temperature water stream to feed the heating system. So, in winter the hot water produced in the thermal collectors is heated up in a boiler before to feed the heating units. The invention proposes a new reversible solar driven absorption machine that in summer it would work as an absorption chiller, as the machines that we can find on the market today, but in winter it would work as a heat transformer. As heat transformer the absorption machine cycle can be driven with a heat source temperature of 40 °C to produce hot water at 60°C at an ambient temperature of 0°C. Furthermore, the lower the ambient temperature, the lower the activation temperature of the machine and higher the machine heating power. Components of both cycles are the same, only the flow direction inside the system and the connection with external devices changes. To allow the reversibility of the equipment and its operation in winter a new working pair, ammonia/lithium nitrate, has been selected because no rectifier is required and it does not present problems of refrigerant freezing at low condensing temperatures when the cycle operates as a heat transformer.

Comprehensive method to assess the technical condition of the pressure equipment of installation operated in the chemical and petrochemical industry A 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.

Device for passive supression of vortex-induced vibrations (VIV) in structures The present invention relates to a device for suppression of Vortex-induced vibrations (known as VIV) in flexible structures or in elastically supported rigid structures. Vortex-induced vibrations are a type of fluid-structure interactions that are consequence of the unsteady periodic forces generated in the wake of bluff bodies when affected by currents. The forces induced on the structures as a result of the large region of separated flow in the wake of the structure, result in vibrations. Vibrations can be fatal in engineering applications. Structures with low mass and damping are the ones in which VIV can be more important. In marine applications, most of the structures are characterised by combined low mass-damping. Although VIV is crucial in marine applications, the invention described here could also be used to prevent VIV in other non-marine scenarios such as structures affected by winds.

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.

Ventilated facade building system of folded sheet without frame A research group from the Department of Architecture of the University of Alcalá (Spain) has developed a ventilated facade system characterized by the incorporation of a folded sheet placed in the middle of the section, which acts as a structural element of the façade and holds the rest of the materials and constituents of the facade. The sheet is folded forming ribs on both sides of the sheet, strengthening the façade and producing suitable modulations for both fixing the outer finishing material and transmitting the loads (own weight and horizontal actions) to the structure of the building by means of fastening elements located in the edge of the floor slab. The group looks for companies in the building sector and manufacturers of facade systems to sign technical cooperation agreements, commercial agreements with technical assistance and patent licensing agreements.
