   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :Anie Kdlian; [2023]
   Nyckelord :Covid-19; Corona virus pandemic; Sweden; Scandinavian countries; Coronavirus; coronaviruspandemin; skandinaviskaländer; Sverige; Data Analysis; Dataanalys; Denmark; Finland; Norway; variants; excess mortality; vaccination; waves of covid; covid cases; stringency index; first wave; second wave; third wave; fourth wave; milda restriktioner.; Mathematics and Statistics;

   Sammanfattning : Covid-19 is the first type of coronavirus that was characterized as a pandemic, year 2020. The prevention methods to minimize the spread of the corona virus did vary somehow between the countries. LÄS MER

3. 2. Classification of almost monomial subalgebras of small codimension

   Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Författare :Ludvig Sundell; [2023]
   Nyckelord :Algebra; Subalgebra; Polynomial; SAGBI basis; LAGBI basis; Lower semigroup; Mathematics and Statistics;

   Sammanfattning : In this text, we study almost monomial subalgebras using LAGBI bases. We introduce the concept of a LAGBI base and present an algorithm for computing them. We then use this algorithm to find, and present in a table, all polynomial subalgebras with Frobenius number smaller than or equal to ten. LÄS MER

4. 3. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :Mahta Keivani Najafabadi; [2023]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

5. 4. The Heraldry of the Vasa Dynasty : Coats of arms as propaganda tools in conflicts with the outside world and within the family

   Master-uppsats, Karlstads universitet/Institutionen för samhälls- och kulturvetenskap (from 2013)

   Författare :Björn Fridén; [2023]
   Nyckelord :Heraldry; History; Early modern history; Vasa Dynasty; Propaganda; State formation; Nobility; Royalty; Sweden; Finland;

   Sammanfattning : During the rule of the house of Vasa 1523-1654, Sweden saw a vastly increased output of new government heraldry and official symbols. This thesis investigates the political motives behind the creation of these symbols and their use as propaganda tools as part of the formation of the Swedish state. LÄS MER

7. 5. A review of the Kaczmarz method

   Kandidat-uppsats, Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

   Författare :Carl Lokrantz; [2023]
   Nyckelord :Kaczmarz method; Least squares; Image reconstruction; Iterative method; Linear system of equations; Projection; Numerical Linear Algebra; Block Kaczmarz; Greedy Kaczmarz; Randomized Kaczmarz; Mathematics and Statistics;

   Sammanfattning : The Kaczmarz method is an iterative method for solving linear systems of equations. The Kaczmarz method has been around since it was developed by Kaczmarz 1937. The main idea behind the original Kaczmarz method is to orthogonally project the previous x_k onto the solution space given by a row of the system. LÄS MER
