Lidar‐Based Object Tracking of Traffic Participants with Sensor Nodes in Existing Urban Infrastructure

Advanced Intelligent Systems, EarlyView.
This paper presents a lidar‐based sensor node design and a rule‐based state observer for edge‐based traffic participant tracking. Unlike other state‐of‐the‐art methods, this state observer enables real‐time, CPU‐only edge processing without relying on machine learning approaches.

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines

Chemie Ingenieur Technik, EarlyView.
Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.
