1. 6. Deep learning for nanofluidic scattering microscopy

   H-uppsats,

   Författare :Gustaf Sjösten; [2021-06-09]
   Nyckelord :data analysis; machine learning; deep convolutional neural networks; nanofluidic scattering spectroscopy; biomolecules; physical chemistry; dark-field microscopy;

   Sammanfattning : A novel technique for label-free, real-time characterization of single biomolecules called Nanofluidic Scatter Microscopy (NSM) has recently been developed by a the Langhammer research group at Chalmers. We have created a machine learning (ML) framework consisting of deep convolutional neural networks such as U-nets, FCNNs, and YOLO in order to characterize single biomolecules through kymographs collected through NSM, as an alternative approach to a standard data analysis method (SA).

3. 7. Overcoming ERP implementation challenges with communication

   Magister-uppsats,

   Författare :Anton Müller; Tasmia Syed; [2021]
   Nyckelord :ERP; Implementation; Communication; Challenges; Effective Communication;

   Sammanfattning : To stay competitive, organizations look to IT systems such as ERPs to assist them in their business goals. While there are organization-wide benefits available for organizations that successfully implement ERPs, the associated risks are great, and many challenges threaten to harm the process. LÄS MER

4. 8. Using Reinforcement Learning to Evaluate Player Pair Performance in Ice Hockey

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Dennis Ljung; [2021]
   Nyckelord :reinforcement learning q-function ice hockey player pair impact nhl context actions markov game model data mining validation score sportlogic;

   Sammanfattning : A recent study using reinforcement learning with a Q-functions to quantify the impact of individual player actions in ice hockey has shown promising results. The model takes into account the context of the actions and captures internal dynamic features of the play which simple common metrics e.g., counting goals or assists, do not. LÄS MER

5. 9. A model for heterogenic catalytic conversion of carbon dioxide to methanol

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Elin Johannesson; [2020]
   Nyckelord :Carbon dioxide; methanol; heterogeneous catalysis; zinc oxide; computational chemistry; density functional theory;

   Sammanfattning : Since our society became industrialised, the levels of carbon dioxide in our atmosphere have been steadily rising, to the point where it in early 2020 at is 413 ppm. The high concentration is causing several troubling effects worldwide because of the increase in mean temperature that it creates, which causes longer draughts, more severe floods, and rising seawater levels to name a few.

7. 10. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Maja Rydgård; [2020]
   Nyckelord :lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

   Sammanfattning : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. LÄS MER
