2. 1. Loss Minimisation in Dynamic Food Processes

   Author : Marcus Henningsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

   Abstract : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. READ MORE

4. 2. Wafer-level processing of ultralow-loss Si3N4

   Author : Marcello Girardi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waveguide; photonic integrated circuit; multilayer integration; ultralow loss; microcombs i; silicon nitride;

   Abstract : Photonic integrated circuits (PICs) are devices fabricated on a planar wafer that allow light generation, processing, and detection. Photonic integration brings important advantages for scaling up the complexity and functionality of photonic systems and facilitates their mass deployment in areas where large volumes and compact solutions are needed, e.
