  1. 1. INFLUENCE OF TEMPERATURE ON BIOMASS AND GROWTH RATE OF BENTHIC DIATOMS

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Evelina Hansson; [2023-06-21]
    Keywords : benthic; diatoms; cultivation; thermal performance; photosynthetic pigments;

    Abstract : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). READ MORE

  3. 2. Can urban tree re-inventories inform future species selection? : diameter at breast height as an indicator for tree performance in Malmö municipality’s tree database

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Hannah Kit Kraynick Braegelmann; [2023]
    Keywords : DBH; ; diameter at breast height; tree inventories; tree re-inventories; urban forestry; species selection; tree management;

    Abstract : Using the inventory database of trees for Malmö municipality, Sweden, this study explored the potential of using the diameter at breast height (DBH) measurement in re-inventories, as a decision-making tool for species selection and management in urban forests. With the escalating pressures of urbanization and unpredictable climate change effects, there is an urgent need for urban forest managers to possess reliable tools that can facilitate the selection of resilient tree species capable of thriving in diverse and changing urban contexts.

  4. 3. Characterization of NOx sensor performance under oscillating pressure conditions

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Álvaro López Méndez; [2023]
    Keywords : NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

    Abstract : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. READ MORE

  5. 4. Head-to-head Transfer Learning Comparisons made Possible : A Comparative Study of Transfer Learning Methods for Neural Machine Translation of the Baltic Languages

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Mathias Stenlund; [2023]
    Keywords : machine translation; transfer learning; Latvian; Lithuanian; low-resource languages; transformers; parent language; child language; comparative study;

    Abstract : The struggle of training adequate MT models using data-hungry NMT frameworks for low-resource language pairs has created a need to alleviate the scarcity of sufficiently large parallel corpora. Different transfer learning methods have been introduced as possible solutions to this problem, where a new model for a target task is initialized using parameters learned from some other high-resource task.

  6. 5. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Erik Lindberg; [2023]
    Keywords : Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

    Abstract : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps. READ MORE
