  1. 1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Ayesha Nagahage; [2024]
    Keywords : Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Abstract : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  3. 2. Change in uptake and transfer of zinc in the food chain when predatory fish disappear from the system

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sara Westerström; [2023]
    Keywords : Aquatic food web; Food chain structure; Trophic transfer; Decline of top predators; Stage-structured biomass model; Pollutants; Heavy metals; Zinc; Akvatisk födoväv; Födovävsstruktur; Trofisk överföring; Minskning av toppredatorer; Stegstrukturerad biomassamodell; Föroreningar; Tungmetaller; Zink;

    Abstract : There is a widespread distribution of possibly toxic heavy metals, such as zinc, in aquatic ecosystems. Simultaneously aquatic food webs are changing due to declining predatory fish stocks. READ MORE

  4. 3. Metrics for Multidimensional Persistence

    University essay from KTH/Matematik (Avd.)

    Author : Daniel Lundin; [2022]
    Keywords : topological data analysis; multidimensional persistence; persistence modules; metrics; noise systems; topologisk dataanalys; multidimensionell persistens; persistensmoduler; metriker; noise system;

    Abstract : A fundamental mathematical object in topological data analysis today is the persistence module. This thesis explores different metrics on multidimensional persistence modules, where spaces are parametrized along multiple dimensions. The focus is especially on metrics constructed by the use of so called noise systems, introduced by Scolamiero et al. READ MORE

  5. 4. Higher Forms and Dimensional Hierarchy in Topological Condensed Matter

    University essay from KTH/Fysik

    Author : Yashar Honarmandi; [2022]
    Keywords : Theoretical physics; topological quantum matter; parametrized systems; Berry phase; higher Berry curvature; effective field theory; topological action; topological insulators; dimensional hierarchy; Teoretisk fysik; topologisk kvantmateria; parametriserade system; Berryfas; högre Berrykrökning; effektiv fältteori; topologisk verkan; topologiska isolatorer; dimensionshierarki;

    Abstract : This report discusses higher differential forms with applications in the study of topological phenomena. The integer quantum Hall effect is first discussed, demonstrating a connection between models on a lattice and quantum field theories bridged by a topological invariant, namely the Chern number.

  6. 5. B-spline Parametrized Approximation and Variation of Vehicle Trajectories For Autonomous Vehicles Simulation

    University essay from KTH/Matematik (Avd.)

    Author : Karolina Siemieniuk; [2021]
    Keywords : ;

    Abstract : A big focus of the Automotive Industry’s work is now on the development ofAutonomous Vehicles (AVs). In order to be able to release them on the market,they need to be tested and validated in a safe and efficient way. That is whycompanies working on the development of AVs use simulation to test the workthey are completing. READ MORE
