1. Feedback Control Goes Wireless: Guaranteed Stability over Low-Power Multi-Hop Networks 

   Mager, Fabian; Baumann, Dominik; Jacob, Romain; et al. (2019)

   ICCPS ’19 ~ Proceedings of the 10th ACM/IEEE International Conference on Cyber-Physical Systems

   Closing feedback loops fast and over long distances is key to emerging applications; for example, robot motion control and swarm coordination require update intervals of tens of milliseconds. Low-power wireless technology is preferred for its low cost, small form factor, and flexibility, especially if the devices support multi-hop communication. So far, however, feedback control over wireless multi-hop networks has only been shown for ...

2. Linear and Nonlinear Optics with Metal Oxides: From Single Nanoparticles to Metasurfaces 

   Timpu, Flavia Claudia (2019)

   Nonlinear optics has become an important part of our technology related daily life since its rapid development right after the invention of laser in 1960. Indeed, it enabled the creation of high-intensity laser pulses, which are used in applications ranging from industrial manufacturing to microsurgery. The development of nonlinear materials allowed the production of very compact and affordable pocket laser pointers and enhanced the power ...

3. Experimental and Numerical Analysis of Pre-Chamber Combustion Systems for Lean Burn Gas Engines 

   Shapiro, Evgeniy; Tiney, Nick; Kyrtatos, Panagiotis; et al. (2019)

   SAE Technical Paper Series

   The current trend in automobiles is towards electrical vehicles, but for the most part these vehicles still require an internal combustion engine to provide additional range and flexibility. These engines are under stringent emissions regulations, in particular, for the reduction of CO2. Gas engines which run lean burn combustion systems provide a viable route to these emission reductions, however designing these engines to provide ...

4. Flame-wall interaction modelling for pre-chamber combustion in lean burn gas engines 

   Hernández, Ignacio; Shapiro, Evgeniy; Tiney, Nick; et al. (2018)

   Lean burn combustion systems present a viable route to emissions reductions. Scavenged pre-chamber ignition (PCI) systems aim to address this challenge by creating favourable ignition conditions close to stoichiometry in the spark region. The lean main charge ignition is then delivered by flame jets propagating through the nozzles connecting the pre-chamber to the cylinder. However, when using pre-chambers in light-duty applications, ...

5. Towards predictive quality management in assembly systems with low quality low quantity data – a methodological approach 

   Gittler, Thomas; Relea, Eduard; Corti, Donatella; et al. (2019)

   Procedia CIRP

   Intervention costs in machine assembly increase rapidly with assembly progress. For early interventions, multivariate control charts or predictive quality management systems can be installed, yet they require large and high-quality datasets. In discrete manufacturing, data is limited by the quantity produced, making it cumbersome to obtain the required quantity for statistical modeling. In this study, a methodology for the setup of ...
