11.5 Gbit/s Transmission Using a 660 mW LiFi Transmitter
For the first time, we demonstrate LiFi transmission with a net data rate of 11.5 Gbit/s using a transmitter with an optical power of 660 mW. Our results pave the way towards next-generation LiFi systems based on high-power VCSEL-arrays.
Beam-Steered Channel Measurement at 160 GHz in an Industrial Environment
Beam-steered channel measurements were analyzed and evaluated on the basis of identified beam pair realizations regarding MIMO capabilities, macro-diversity gains and blockage effects for a multi-transmitter industrial sub-terahertz communication...
Short Range Optical Wireless Communication at 67.8 Gbit/s using a Multiaperture VCSEL
We demonstrate a point-to-point optical wireless communication link for fixed wireless access scenarios using a multiaperture VCSEL. At 5 meters distance, a record net data rate of 67.8 Gbit/s is reached after LDPC FEC.
Catalytically active plate heat exchanger for flexible hydrogen release from perhydro benzyltoluene
A catalytic plate reactor derived from the design of conventional plate heat exchangers was used for the continuous and dynamic dehydrogenation of perhydro benzyltoluene, a LOHC. The surface of heat exchanger plates has been catalytically...
Software for dataset-wide XAI: From local explanations to global insights with Zennit, CoRelAy, and ViRelAy
The predictive capabilities of Deep Neural Networks (DNNs) are well-established, yet the underlying mechanisms driving these predictions often remain opaque. The advent of Explainable Artificial Intelligence (XAI) has introduced novel...
Leveraging Shared Data and Models for ML-Based QoT Estimation: Toward Standardized and Generalizable Models
