  1. 1. Hur platt är platt? : En kvalitativ studie om icke-hierarkiska organisationer

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Emma Lundström Wittenfelt; Lotten Stedt; [2023]
    Nyckelord :Flat organizations; non-hierarchical organizations; heterarchies; group theory; self-organization; teams; power dynamics; power structures; phenomenology; leadership; and organization.; Platta organisationer; icke-hierarkiska organisationer; heterarkier; gruppteori; självorganisering; team; maktdynamik; maktstrukturer; fenomenologi; ledarskap och organisation.;

    Sammanfattning : Syftet med denna studie är att förstå hur fenomenet platthet fungerar och upplevs i organisationer samt att få en ökad förståelse för självorganisering och formella och informella strukturer i icke-hierarkiska organisationer. En experimentell fenomenologisk studie gjordes på svenska platta organisationer med kriteriet få eller inga mellannivåer av chefer. LÄS MER

  3. 2. Dimensionality Reduction in High-Dimensional Profile Analysis Using Scores

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Jonathan Vikbladh; [2022]
    Nyckelord :High-dimensional data; Hypothesis testing; LR test; Linear scores; Multivariate analysis; Profile analysis; Spherical distributions;

    Sammanfattning : Profile analysis is a multivariate statistical method for comparing the mean vectors for different groups. It consists of three tests, they are the tests for parallelism, level and flatness. The results from each test give information about the behaviour of the groups and the variables in the groups.

  4. 3. An analysis of the turbulent properties of a CME

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Roque Márquez Rodríguez; [2022]
    Nyckelord :CME; turbulence; plasma; solar wind; MHD;

    Sammanfattning : Spectral indices and flatness scaling exponents corresponding to solar wind plasma measurements before, during and after a coronal mass ejection (CME) detected by NASA's Wind spacecraft on September 2014 have been obtained. The Politano-Pouquet (PP) law for isotropic and incompressible magnetohydrodynamic (MHD) turbulence has been validated over a series of selected time intervals. LÄS MER

  5. 4. Charge transfer states at polymer solar cell interfaces : Insights from atomic-scale modeling

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Rickard Svensson; [2022]
    Nyckelord :organic solar cells; OSC; polymer; interface; charge transfer; non-fullerene acceptor; PYT; PBDB-T; DFT; TD-DFT; conformation; alkyl groups; methylation; HOMO; LUMO; FMO; NTO; UV-Vis; DOS; exciton; exciton binding energy; dipole moment; open-circuit voltage; organiska solceller; OSC; polymer; gränssnitt; laddningsöverföring; icke-fullerenacceptor; PYT; PBDB-T; DFT; TD-DFT; konformation; alkylgrupper; metylering; HOMO; LUMO; FMO; NTO; UV-Vis; DOS; exciton; excitonbindningsenergi; dipolmoment; tomgångsspänning;

    Sammanfattning : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

  7. 5. Motion Planning for Aggressive Flights of an Unmanned Aerial Vehicle

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Cornelia Smith; Filippa Femic; [2022]
    Nyckelord :UAV; autonomous vehicle; motion planning; polytope intersection; trajectory generation; obstacle handling; collision avoidance; feasibility constraints; differential flatness;

    Sammanfattning : Unmanned aerial vehicles are becoming more popular in today’s society, which results in the rise of laws intended to maintain safety. To abide by these, while allowing the technology to expand, functioning path-planning algorithms are required.This also includes having methods for detecting and managing obstacles. LÄS MER
