    University essay from Lunds universitet/Innovationsteknik

    Author : Rebecca Ahlin; Anna Malmberg; [2023]
    Keywords : Carbon accounting; carbon disclosure; carbon management; carbon management tools; environmental change management; internal carbon price; Technology and Engineering;

    Abstract : Background: Climate change is becoming a more urgent issue, where global agreements and regulations are putting pressure on companies to calculate and disclose their greenhouse gas emissions to combat the problem. Other driving forces of carbon disclosure for companies include social, economic, and financial pressure, as well as firm specific internal factors. READ MORE

  3. 2. The Banach-Tarski paradox

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Carl Elofsson; Adrian Nilsson; Nicolas Söderberg; Tim Westlund; [2022-07-04]
    Keywords : ;

    Abstract : In this thesis we present a proof of the Banach-Tarski paradox, a counterintuitive result that states that any ball in R3 can be cut into finitely many pieces and then be reassembled into two copies of the original ball. Since the result follows from the axiom of choice it is important for assessing its role as an axiom of mathematics. READ MORE

  4. 3. Perron–Frobenius theorem and Z≥0[S3]-semimodules

    University essay from Uppsala universitet/Algebra, logik och representationsteori

    Author : Mikolaj Cuszynski-Kruk; [2022]
    Keywords : ;

    Abstract : In this thesis, the Perron–Frobenius theorem which in its most general formstates that the spectral radius of a non-negative real square matrix is an eigenvaluewith a non-negative eigenvector, is proven. Related properties arederived, in particular the Collatz–Wielandt formula and a general form of anon-negative idempotent matrices. READ MORE

  5. 4. Investigation and evaluation of optical distance sensors

    University essay from Uppsala universitet/Signaler och system

    Author : Olof Wigzell; [2022]
    Keywords : optics; radiometry; senssor; microcontroller; irradiance; circuit design; calibration; validation;

    Abstract : Optical sensors are among the sensors that are often used for distance measurements. An optical distance sensor is basically made of a light emitter (Tx) such as a light emitting diode (LED), a light receiver (Rx) such as a photosensitive transistor, and a circuit supporting the operation of the Tx and Rx.

  6. 5. Intern användning och export av Cytivas spillvärme

    University essay from SLU/Dept. of Energy and Technology

    Author : Mohamad Karam Alhomsi; John Bankefors; Tanapon Bredin; Malko Riche; Tim Selin; Henrik Sollenberg; [2022]
    Keywords : spillvärme; industri; fjärrvärme; kylsystem; värmepump;

    Abstract : Today there is a big potential in recycling waste heat at large-scale production sites. In this report the ability to reuse heat from Cytiva’s industrial facilities C7, C8 and C9 located in Uppsala is examined. The purpose is to analyze the need of heat for two on-site buildings and how the buildings will be provided by waste heat. READ MORE
