  1. 1. Constructing Subalgebras of K[x] Using the Minimal Polynomial

    University essay from Lunds universitet/Matematik LTH

    Author : Marianne Ljunggren; [2023]
    Keywords : Algebra; Subalgebra; Polynomial Algebra; Minimal Polynomial; Mathematics and Statistics;

    Abstract : In this report we will be working with subalgebras A of finite codimension in K[x]. It is known that such subalgebras can be expressed using a set of linear conditions evaluated at a finite set of points called the spectrum elements of A. READ MORE

  3. 2. Use cases for traceability systems : An explanatory case study about the application areas for QR codes

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Oliver Strömberg; [2023]
    Keywords : Product service systems; Use phase data; Use cases; QR code; Manufacturing;

    Abstract : The customer concept becomes more intertwined with the provider of products as serviceoriented business models is offered to the customer. This shift is referred as servitization in which innovation occurs in the company processes by shifting focus from providing products to providing product service systems (PSS). READ MORE

  4. 3. Design of a transport box for bicycle that can be converted into a cargo trailer

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Tim Friedrich Wimmelbacher; [2023]
    Keywords : vehicle; bicycle; trailer; transportation; design; fordon; cykel; släp; transport; konstruktion;

    Abstract : Both commuting to work and long-distance travelling with one's own bicycle have been intrend for years and a large market has emerged. While the reasons on the customer side aremainly sustainability and sporting activity, the companies offer customised products for manydifferent use-cases. READ MORE

  5. 4. On the (1/2,1/2) Representation of the Lorentz Group and the Discrete CPT Symmetries

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Nikolaj Skog Pirinen; [2021]
    Keywords : The Lorentz Group; Group Theory; Quantum Field Theory; CPT; Symmetry; Spinors; Representation Theory; Physics and Astronomy;

    Abstract : This thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct product basis.

  6. 5. Tool support for the derivation of product line use cases : A case study in the railway transportation domain

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Viking Forsman; [2021]
    Keywords : Use Case; Use Case Template; Product Line Engineering; Requirement Engineering; Textual Specification; Variability; Commonality; Tool Support;

    Abstract : Use cases are textual artifacts used to define the expected behavior of a system. However, use cases become more complicated when applied in a product line context since they need to define the behavior of several systems. READ MORE
