  1. 6. Riparian forests : a comparison of tree diversity, deadwood and canopy cover between primary and production riparian forests along headwaters

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Eric Lundqvist; [2022]
    Keywords : riparian forest; primary forest; production forest; tree diversity; deadwood; canopy cover;

    Abstract : Headwaters and their adjacent riparian forests (RF) have been recognized for years for their tight interlinkage and essential ecological and biogeochemical services. Notwithstanding, headwaters in Sweden have historically been overlooked in forest management, which has led to conifer-dominated RFs with simplified even-age structure. READ MORE

  3. 7. Energy and Strength-based Criteria for Intralaminar Crack Growth in Regions with High Stress Gradients

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anish Niranjan Kulkarni; [2021]
    Keywords : Cross-ply composites; High crack density; Stress gradient; FEM; Stress analysis; Strain Energy Release Rate;

    Abstract : Cross-ply composite laminates can develop very high density of transverse cracks in the 90-layer under severe thermal and mechanical loading conditions. At such high crack densities, two adjacent cracks start to interact, and a stress gradient is created in the region between these cracks. READ MORE

  4. 8. Solution of the neutrals species in a weakly ionised plasma by means of the SIMPLE algorithm

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

    Author : Alberto Zorzetto; [2021]
    Keywords : Boundary conditions; Helicon Plasma Thruster; Neutrals species; OpenFOAM®; Plasma; SIMPLE; Gränsvillkor; Helicon Plasma Thruster; Neutrala Partiklar; OpenFOAM®; Plasma; SIMPLE;

    Abstract : In recent years, the Helicon Plasma Thruster (HPT) has become one of the most promising technologies of in-space electric propulsion. T4i Technology for Propulsion and Innovation S.P.A. READ MORE

  5. 9. Thermal Acoustic Flow inside an Ultrasound Resonator

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Enrico Corato; [2020]
    Keywords : Microfluidics; Ultrasound; Acoustofluidics; Thermal gradient; Thermoacoustic; Technology and Engineering;

    Abstract : This thesis aims at investigating the interaction between thermal gradients and acoustic fields in microfluidic devices. In the research branch of Acoustofluidics, which bridges together acoustics and fluid dynamics, inhomogeneity in the medium has gained great interest due to the novel physics behind and the potential in manipulating submicrometer particles.

  6. 10. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Nicoline Krogh Hemme; [2020]
    Keywords : Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

    Abstract : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. READ MORE
