1. 1. Improvements in Energy Efficiency of Vacuum Dewatering of Greaseproof Paper : Simulation of a Triple Vacuum Suction Box in Laboratory Scale

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Björn Öman; [2023]
   Keywords : Vacuum dewatering; greaseproof paper; triple vacuum suction box; grammage; energy efficiency; dryness; Vakuumavvattning; greaseproofpapper; trippelvakuumsuglåda; ytvikt; energieffektivitet; torrhalt;

   Abstract : Vacuum dewatering of paper is a heavily energy expensive process, even more so for greaseproof paper, which is one of the main products at Nordic Paper Seffle AB. Due to this being such an energy demanding process, improvements in the vacuum dewatering could save massive amounts of energy. READ MORE

3. 2. Study of the temperature profile during industrial coating process

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Gustav Isberg; [2022]
   Keywords : Coating; Surface temperature; PVOH; Barrier;

   Abstract : Drying rate during industrial coating application is important to understand because drying a coated paper requires energy. If an unnecessary high amount of energy is used to dry paper, a fast evaporation rate can be achieved which can result in defects of the coated surface. READ MORE

4. 3. Crosslinked Cartonboard - Challenges and possibilities

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Malin Elvin; [2022]
   Keywords : Cartonboard; crosslinking; mechanical properties; SCT;

   Abstract : The need for sustainable packaging is growing, and plastic waste needs to be reduced. A suitable alternative could be fibre-based packaging and cartonboard, and several actions could enhance this alternative. This study investigates crosslinking, a method to create stronger bonds between the OH-groups in the material. READ MORE

5. 4. GPS Tracking Device

   University essay from

   Author : Ivet Shami Jamil; [2022]
   Keywords : GPS tracker; SIM808; Telit GM862-GPS; Arduino Uno; Flutter;

   Abstract : The project was performed in collaboration with the company Prevas AB. The aim of the project was to implement a GPS tracking device, or a GPS tracker, that has a hardware setup retrieving the GPS position of an object and then sends the position through a mobile communication module to a smartphone.

6. 5. Diagnosis of Synoptic Weather Patterns Causing Heavy Rainfall Occurrence Using Self-Organizing Maps

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Aoi Kasai; [2021]
   Keywords : Self-Organizing Map; heavy rainfall frequency; classification; meteorological fields; prediction; heavy rainfall risk; Technology and Engineering;

   Abstract : The annual number of events with precipitation over 50 mm/h have increased from 1970s and this trend is likely to be continued due to climate change in Kyushu, Japan. Therefore, it is important to recognize what kind of meteorological fields have contributed to the occurrence of heavy rainfall events and to reveal whether it is possible to diagnose heavy rainfall risk.
