  1. 1. Analyzing common structures in Enterprise Architecture modeling notations

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ahmed Abdallah Hussein Mohammed; [2022]
    Nyckelord :Enterprise Architecure; Enterprise Architecure Framework; Multilevel Modeling; Taxonomy; Företagsarkitektur; Ramverk för Företagsarkitektur; Flernivåmodellering; Taxonomi;

    Sammanfattning : Over the past few decades, the field of Enterprise Architecture has attracted researchers, and many Enterprise Architecture modeling frameworks have been proposed. However, in order to support the different needs, the different frameworks offer many different elements types that can be used to create an Enterprise Architecture. LÄS MER

  3. 2. Battery Digital Twin : Modeling and Characterization of a Lithium-Ion Battery

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Fabian Sund; Gustav Erbing; [2021]
    Nyckelord :Electrical vehicles; Lithium-ion batteries; Modular multilevel converter; Two-level converter; Thermal characteristics;

    Sammanfattning : Electrical vehicles have become more popular during recent years due to their reduced greenhouse gas emissions. The research within Li-ion batteries is therefore moving fast. Presently, two-level converters transforming the current from DC to AC. LÄS MER

  4. 3. Patient attachment and reflective functioning as predictors for therapist countertransference

    Uppsats för yrkesexamina på avancerad nivå, Linnéuniversitetet/Institutionen för psykologi (PSY)

    Författare :Jonatan Bjerén; Fredrik Eriksson; [2021]
    Nyckelord :Countertransference; Attachment; Reflective Functioning; Mentalization; Psychotherapy; Multilevel modeling; Motöverföring; Anknytning; Reflektivt fungerande; Mentalisering; Psykoterapi;

    Sammanfattning : Therapists’ reactions towards patients are important for the therapeutic process, and is influenced by therapist and patient characteristics. This study aimed to improve the understanding of therapists’ emotional reactions by investigating if patients’ attachment and ability to mentalize predicted therapist countertransference in psychotherapy.

  5. 4. Who will survive in Stockholm Archipelago? : A longitudinal analysis of firm-survival in a peripheral region

    Master-uppsats, Södertörns högskola/Företagsekonomi

    Författare :Youssouf Merouani; [2020]
    Nyckelord :firm-survival; Stockholm Archipelago; peripherality; multilevel modeling; three-level lo-gistic regression.;

    Sammanfattning : This longitudinal study investigates firm-survival in a peripheral region. The analysis relies on a unique longitudinal dataset, encompassing all firms in 17 Stockholm Archipelago islands during 2000-2019, collected through data triangulation methods. LÄS MER
