  1. 1. Barn under samhällets vingar : Den sociala barnavården i Kalmar, Arby och Dörby under åren 1926–1931 och 1946–1951

    Master-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :Angelica Wickman Tiller; [2024]
    Nyckelord :Fosterbarn; Fosterfamilj; Barnavårdsnämnd; Omplacering; Barnavårdslag;

    Sammanfattning : This study aims to examine aspects related to children who were taken into custody by the Child Welfare Council in the city of Kalmar, as well as the countryside communities of Dörby and Arby, during the years 1926-1931 and 1946-1951. The study highlights the social vulnerability that followed and the circumstances in which the children and parents found themselves in, which influenced their placement. LÄS MER

  3. 2. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Ellen Pääjärvi Våg; [2024]
    Nyckelord :Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

    Sammanfattning : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. LÄS MER

  4. 3. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Daniel Milenkovic; [2023]
    Nyckelord :Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Sammanfattning : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.

  5. 4. En fjärils vingslag : 'Gängkriminalitetens' dolda ideologi - En kritisk diskursanalys

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för pedagogik och lärande (PEL)

    Författare :Mathilda Åkesson; Sofie Nilsson; [2023]
    Nyckelord :Kritisk diskursanalys; Opinionstexter; Gängkriminalitet; Identitet; Framställning; Positionering;

    Sammanfattning : Studiens syfte var att bidra med kunskap om hur gängkriminell identitet konstrueras isamhällsdebattens språkbruk. Studiens teoretiska ramverk och metodologiska ansats varFaircloughs kritiska diskursanalys (CDA). LÄS MER

  7. 5. Dynamic response of damped attachments in fighter applications

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Katja Nordström; [2023]
    Nyckelord :Vibration isolator; printed circuit board; vibrations; natural frequency; Vibrationsisolator; kretskort; vibrationer; resonansfrekvenser;

    Sammanfattning : This thesis investigates the impact of vibration isolators on circuit boards during harsh vibrationenvironments that occur when they are mounted on the wings of a fighter jet. To examine thisphenomenon, a mathematical model and a simulated model were developed to determine theresonant frequencies of the circuit board under various boundary conditions. LÄS MER
