  1. 1. Do viscous flows slip?

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Björn Sjösvärd; [2023-12-21]
    Keywords : Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Abstract : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. READ MORE

  3. 2. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

    University essay from KTH/Tillämpad fysik

    Author : Jonathan Karlsson; [2023]
    Keywords : Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

    Abstract : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

  4. 3. Local Nature Matters : A Story of How Empowerment from Tourism Contributes to Local Nature Stewardship in Rural Communities

    University essay from Linnéuniversitetet/Institutionen för marknadsföring och turismvetenskap (MTS)

    Author : Sarah Nieutin; [2023]
    Keywords : Place attachment; resident empowerment through tourism; nature stewardship; care for nature; resident attitudes towards nature stewardship; nature’s contribution to people framework; social exchange theory;

    Abstract : This Master thesis examines the role of resident empowerment in rural nature tourism in shaping the relations between how residents engage with local places and local nature stewardship in Plouguerneau, France. Through a conceptual framework that includes the concepts of empowerment, place attachment, care for nature, and nature stewardship, the study models the effect of place attachment and care for nature on resident stewardship attitudes and how resident empowerment in tourism mediates this relationship.

  5. 4. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Georgios Nentidis; [2023]
    Keywords : ;

    Abstract : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

  6. 5. Exchanging 'Life' for Money? Overtime work culture and professional women's fertility intentions in China

    University essay from Lunds universitet/Graduate School

    Author : Jinxuan Lu; [2023]
    Keywords : Fertility intention; Overtime work; PLS-SEM; Vignette experiment; Theory of Planned Behavior; Social Sciences;

    Abstract : In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertility intentions among working women of reproductive age in urban China.
