  1. 16. Numerical Simulation of Soliton Tunneling

    University essay from

    Author : Matilda Tiberg; Elias Estensen; Amanda Seger; [2020]
    Keywords : soliton; GPE; gross pitaevskii; Schrödinger; step potential; summation by parts; SBP-SAT; Simultaneous approximation term; SAT; Projection; SBP-Projection; finite differences; boundary treatment; interface treatment;

    Abstract : This project studied two different ways of imposing boundary conditions weakly with the finite difference summation-by-parts (SBP) operators. These operators were combined with the boundary handling methods of simultaneous-approximation-terms (SAT) and the Projection to impose homogeneous Neumann and Dirichlet boundary conditions.

  3. 17. Polymer Assisted Transfer of Graphene onto Semiconductor Substrates

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Synkrotronljusfysik

    Author : Jonathan Frisby; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Since first being isolated in 2004, Graphene has been researched heavily because of its unique properties. Recently, interest has grown in graphene/semiconductor heterostructures. In this work, the transfer of graphene through the use of cellulose acetate butyrate (CAB) polymer is studied. READ MORE

  4. 18. Applying FQ-CoDel For Packet Schedulers In Tunneled Transport Layer Access Bundling

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Felix Andersson Johansson; [2020]
    Keywords : Networking; QUIC; PQUIC; FQ-CoDel;

    Abstract : The number of devices and internet traffic for applications connected to the internet increases continuously. Devices provide increasing support for multi-homing and can utilize different access networks for end-to-end communication. READ MORE

  5. 19. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling

    University essay from Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Björn Elfving; Aron Sandström; [2020]
    Keywords : Access-shafts; FE-modelling; Plaxis; Robot; Elliptical; Circular; Optimisation; Geotechnical; Engineering; Retaining; Structures; Tunnel; Soil; Interaction; Technology and Engineering;

    Abstract : Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. READ MORE

  6. 20. An STM-based study of Bi deposition on InAs(110)

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Tobias Alpskog; [2020]
    Keywords : Bismuth; Deposition; STM; Physics and Astronomy;

    Abstract : III-V semiconductor compounds containing Bi, such as InBi, have recently attracted much attention due to predictions of band inversion and topological insulators. The predictions showed that films of InBi could be applicable in quantum computers and at room temperature. READ MORE
