  1. 6. Visual neurons with different shapes: investigation of the relationship between morphology and function

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Love Federley Ottosson; [2020]
    Keywords : Biology and Life Sciences;

    Abstract : In this project, morphological differences between motion detector neurons in Drosophila melanogaster were compared and used to speculate regarding their function. This was achieved by comparing properties such as diameter, height, width, bifurcation, asymmetry and terminal degree. READ MORE

  3. 7. Implementation of the Todd-Coxeter Algorithm to Finitely Presented Groups

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Tomas Reed; [2018]
    Keywords : Group Theory; Free Groups; Finitely Presented Groups; Todd-Coxeter Algorithm; Combinatorial Group Theory; Mathematics and Statistics;

    Abstract : This work presents the notion of free groups and the definition of a group using generators and relations. We use the Todd-Coxeter Algorithm in order to solve the coset enumeration problem for the finitely presented groups: $D_4,\, A_4,\, A_5,\, S_3,\, S_4,\, S_5,\, PSL_2(7),\, PSL_2(9)$. READ MORE

  4. 8. An Investigation of the Trinification Scalar Sector at One Loop

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Laurie Walk; [2017]
    Keywords : GUT; Trinification; Spontaneous Symmetry Breaking; Effective Field Theory; Effective Potential; Physics and Astronomy;

    Abstract : Throughout this work we investigate a trinification-based grand unification theory (GUT) with a global family symmetry, as a radiative origin of the Standard Model (SM). We show that after spontaneous symmetry breaking of the trinification gauge group, we can in theory construct an effective left-right symmetric model (LRSM) which breaks to the SM gauge group through radiative breaking induced by the running of the model’s parameters.

  5. 9. Efficient Group Key Management for Internet of Things

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Kiki Rizki; [2016]
    Keywords : GREP; group key management; secure group communication; Internet of Things; GREP; gruppnyckelhantering; säker gruppkommunikation; Internet of Things;

    Abstract : The Internet of Things has become the next big step of a general Internetevolution, and conveys the assurance of security as one of the biggest challenge.In particular, use cases and application scenarios that adopt groupcommunication schemes need to be properly secured, in order to protect themessage exchange among group members from a number of security attacks.

  6. 10. Left-right-symmetric model building

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Eric Corrigan; [2015]
    Keywords : Theoretical physics; particle physics; high-energy physics; left-right symmetry; grand unification; GUT; beyond standard model physics; BSM physics; Physics and Astronomy;

    Abstract : We have studied left-right-symmetric (LR) model building in two specific instances: the Minimal Left-Right-Symmetric Model (MLRM), with gauge group SU(3)_C × SU(2)_L × SU(2)_R × U(1)_{B-L} and parity as the LR symmetry; and a non-supersymmetric, trinified theory, with gauge structure SU(3)_L × SU(3)_R × SU(3)_C × Z_3 and an additional, novel, SU(3) family symmetry. For the MLRM, we have rederived the Lagrangian in the gauge and mass eigenbases, partly using the SARAH model building framework. READ MORE
