In industrial environments, especially in power stations and the oil and gas area, leaks in pipe systems, valves and at critical transfer points have to be identified as quickly as possible. This is essential for taking the appropriate steps in sufficient time.
Undetected leaks can lead to unplanned downtime and - for example in the case of oil - to pollution of the environment. They also have the potential to impair the quality of a plant's production. However, in certain environments, loss of pressure, temperature changes, and the development of fumes or smoke is difficult to monitor and results are often inaccurate at best. In many cases, there is no suitable sensor system, or installing one would be too expensive. Moreover, specialized sensors can only detect specific types of leaks.
For this reason Siemens developed the ViaCC software for video analysis. It contains detection methods that can be freely combined and that are suitable for detecting edges, colors, movements and so on. Up to twelve cameras record and transmit about 200 images per second to each server. ViaCC can be fully integrated into a range of automation systems, such as T2000/3000 and PCS 7, or even into third-party systems via a gateway. The automation state and the live situation are directly coupled. This enables process data to be inserted directly into a video image and saved. Images can also be displayed and/or recorded as a function of the process. The video detection data, for example of an edge deviation or a color change, are then fed back into the automation system.
The live images of a fault enable service to be better planned with appropriate spare parts and tools. The subsequent analysis of the video data showing the course of a fault can be used later as the basis for future optimization measures to increase plant availability.
The ViaCC video analysis is used, among others, to monitor critical sections of pipelines and detect smoldering fires and the evolution of smoke in enclosed spaces. ViaCC can also be adapted for use in specific industries and to customer requirements by combining the various detection methods.The ViaCC video solution for detecting leaks in an industrial environment

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
