    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Staikos; [2024]
    Nyckelord :Physical Geography; Ecosystem Analysis; Bike-sharing demand; Machine learning; Deep learning; Spatial regression; Graph Convolutional Neural Network; Multiple Linear Regression; Multilayer Perceptron Regressor; Support Vector Machine; Random Forest Regressor; Urban environment; Micro-mobility; Station planning; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : Public Bike-Sharing systems have been employed in many cities around the globe. Shared bikes are an efficient and convenient means of transportation in advanced societies. Nonetheless, station planning and local bike-sharing network effectiveness can be challenging. LÄS MER

  3. 2. Cultivating connections: exploring the impact of community garden on social cohesion : in a socio-economic disadvantaged neighbourhood in Sweden

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Reham Ghallab; [2024]
    Nyckelord :Social cohesion; social capital; community garden; socio-economic neighbourhoods; segregation;

    Sammanfattning : The study delves into the interplay between the social dynamics of the community garden space and broader socio-political forces, exploring how these factors mold practices and interactions within the community garden, thereby influencing social cohesion. Despite the apparent segregation, Tensta Garden serves as a catalyst, inspiring residents to construct relationships, actively participate, and cultivate connections and shared experiences. LÄS MER

  4. 3. CFD-simulering av värmeöverföring under upptändningsförlopp av krutraketmotor

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Carl-Otto Olsson Sjögren; [2024]
    Nyckelord :Computational Fluid Dynamics; CFD; Anfyrning; upptändning; CFD; strömningslära; värmeöverföring; termisk strålning; krutraketmotor; konvektion;

    Sammanfattning : SAAB Dynamics producerar och utvecklar flertalet produkter som innehåller krutraketmotorer. Krutraketmotorers prestanda är kraftigt beroende av en effektiv upptändning och det är önskvärt att kunna prediktera detta förlopp numeriskt med god noggrannhet. Ingen etablerad simuleringsmetodik existerar i dagsläget. LÄS MER

  5. 4. Barns semiotiska uttryck i dansen : En kvalitativ studie av hur tre designade dansaktiviteter underlättar barns användning av semiotiska resurser.

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för lärande, humaniora och samhälle

    Författare :Evelyn Egina Wass; Angeline Emano Karlsson; [2024]
    Nyckelord :communication; dance in preschool; social semiotics; semiotic; semiotic resource; transduction; children s meaning-making; kommunikation; dans i förskolan; socialsemiotik; semiotisk; semiotisk resurs; transduktion; barns meningsskapande;

    Sammanfattning : This study highlights the complex ways in which children engage with semiotic resources during designed dance activities. The study explores how preschool children aged four to five use semiotic resources during dance activities. The aim is to investigate the children's use of symbolic expressions and the communicative dynamics involved. LÄS MER

  7. 5. Bridging Nature and Care : nurturing Individuals with Dementia in a Residential Care Facility in Denmark

    Master-uppsats, SLU/Dept. of People and Society
