1. 16. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Frida Nilsson; [2023]
   Nyckelord :CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

   Sammanfattning : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. LÄS MER

3. 17. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Teodor Bucht; [2023]
   Nyckelord :Toeplitz matrices; Banded Toeplitz matrices; Limit set; Eigenvalues; Mathematics and Statistics;

   Sammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER

4. 18. Particle Detection in Bone Marrow Using CNNs and Transformer Networks

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Anna Källén; Marcus Williams; [2023]
   Nyckelord :Bone Marrow; Dark Field Microscopy; Fourier Ptychography; Machine Learning; Convolutional Neural Networks; Transformer Networks; Quantisation; Technology and Engineering;

   Sammanfattning : The critical role of hematological stem cells, concentrated in bone marrow, in disease diagnosis makes the detection of these cells an imperative task. The current process, however, is slow and heavily reliant on expert interpretation, underscoring the need for automation. LÄS MER

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

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Marianne Ljunggren; [2023]
   Nyckelord :Algebra; Subalgebra; Polynomial Algebra; Minimal Polynomial; Mathematics and Statistics;

   Sammanfattning : 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. LÄS MER

7. 20. Carbon Capture for Biomass Combustion

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Anders Amundsson; [2023]
   Nyckelord :beccs; ccs; carbon capture; AMP DMSO; amine absorption; heat integration; chemical engineering; environmental engineering; Technology and Engineering;

   Sammanfattning : In order to limit global warming, bioenergy carbon capture and storage (BECCS) technologies are getting increased attention. To meet emission scenarios, an estimated 4000 carbon capture plants are expected to be required by 2030, indicating that progress in carbon capture and storage (CCS) deployment is currently lagging behind expectation.
