1. 1. Using cloud services and machine learning to improve customer support : Study the applicability of the method on voice data

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Henrik Spens; Johan Lindgren; [2018]
   Keywords : speech-to-text; machine learning; natural language processing;

   Abstract : This project investigated how machine learning could be used to classify voice calls in a customer support setting. A set of a few hundred labeled voice calls were recorded and used as data. The calls were transcribed to text using a speech-to-text cloud service. READ MORE

3. 2. Fluid-Structure Interaction; Numerical Modelling andExperimental Comparison

6. 5. Anaerobic Digestion of Fractionated and Non-fractionated Sugar Beet Tops

   University essay from Lunds universitet/Bioteknik; Lunds universitet/Kemiska institutionen

   Author : Johan Lindgren; [2014]
   Keywords : Anaerobic Digestion; Biogas; Biotechnology; Bioteknik; Technology and Engineering;

   Abstract : Continuous stirred tank reactors (CSTR) and batch reactors were used to examine the difference in methane yields and process stability between fractionated and non-fractionated sugar beet leaves. The hypothesis of this project was that by reducing the amount of juice in the sugar beet leaves the amount of soluble sugars and other easily fermented compounds in the substrate will also decrease, and thereby lead to higher process stability.
