Cyber-Physical-Systems for Fluid Manufacturing Systems

Increased volatility continues to challenge the automotive manufacturer's production performance. More than a century after the start of mass production, changeable production systems that allow the flexibility for the economic mass production of customized products have arisen. Limitations on established production systems are driving the development of changeable production systems like the Fluid Manufacturing System (FLMS). In an FLMS, the individual production modules are mobile and consist of Cyber-Physical Systems (CPS) which can be combined ad-hoc to adapt to changing requirements. By connecting different CPS - e.g., Autonomous Mobile Robots (AMR) or smart load carriers - adaptable and flexible production will be achieved. This paper presents the first real-world initiation of an FLMS with the design and development of CPS and digital twins for production and logistics at the ARENA2036 research campus

Increasing the Astrophysical Reach of the Advanced Virgo Detector via the Application of Squeezed Vacuum States of Light

Current interferometric gravitational-wave detectors are limited by quantum noise over a wide range of their measurement bandwidth. One method to overcome the quantum limit is the injection of squeezed vacuum states of light into the interferometer’s dark port. Here, we report on the successful application of this quantum technology to improve the shot noise limited sensitivity of the Advanced Virgo gravitational-wave detector. A sensitivity enhancement of up to 3.2±0.1  dB beyond the shot noise limit is achieved. This nonclassical improvement corresponds to a 5%–8% increase of the binary neutron star horizon. The squeezing injection was fully automated and over the first 5 months of the third joint LIGO-Virgo observation run O3 squeezing was applied for more than 99% of the science time. During this period several gravitational-wave candidates have been recorded
