1. 1. Feature Selection for Microarray Data via Stochastic Approximation

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Erik Rosvall; [2024-03-18]
   Nyckelord :feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

   Sammanfattning : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. LÄS MER

3. 2. FÖRSTÅR, KAN OCH VILL LÄNDERIMPLEMENTERA PARISAVTALET? : Fyra länders kontexter och förutsättningar för att implementera Parisavtalet

   Kandidat-uppsats, Örebro universitet/Institutionen för humaniora, utbildnings- och samhällsvetenskap

   Författare :Hanna Andersson Wallén; Alma Spector; [2024]
   Nyckelord :Paris Agreement; implementation theory; climate action; countries NDCs;

   Sammanfattning : The purpose of the study is, based on implementation theory and Lennart Lundquist’s three concepts- understanding, capability, and willingness, to identify whether these factors can affect the implementation of the Paris Agreement in four countries. Through a qualitative text analysis of the NDCs (Nationally Determined Contributions) of four countries, using understanding, capability, and willingness as categories, various aspects have been identified and are presented in the results.

4. 3. Det tysta sammanbrottet i en liberal demokrati : Idékritik på hegemonisk makt i det japanska civilsamhället

   Kandidat-uppsats, Stockholms universitet/Statsvetenskapliga institutionen

   Författare :Nao Sakurada; [2024]
   Nyckelord :Civilsamhälle; Marxism; Hegomoni; Sociala rörelser; Demokrati; Motstånd; John Holloway;

   Sammanfattning : The purpose of this essay is to examine the conditions for civil society and activists in Japan regarding their access to a truly free capability for their expression, action, and thoughts. The theoretical starting point is based on Iris Young's normative theory of the function of civil society in deliberative democracy, which sheds light on intermediate factors that make Young's ideal too naive to be realized.

5. 4. Svensk underrättelseinhämtning och organisationskultur under 1939/1940 : En studie av försvarsstabens fokus på sovjetisk styrkeuppbyggnad i Estland genom en kvalitativ text- och kulturanalys

   Kandidat-uppsats, Försvarshögskolan

   Författare :Sofia Olsson; [2024]
   Nyckelord :Underrättelseinhämtning; organisationskultur; försvarsstaben; militärattaché; sovjetisk styrkeuppbyggnad;

   Sammanfattning : This study is about a mapping of the Swedish Defense Staff's focus area for information gathering regarding the Soviet military capability, based on their military build-up in Estonia during the fall of 1939 and the spring of 1940. Relevance for this study is found in the research gap identified in previous research and intends to be able to produce a deeper understanding of the defense staff's view of the military-strategic significance of the Soviet Union's military build-up.

7. 5. Microbial production of chemical building blocks from lignin

   Master-uppsats, Lunds universitet/Teknisk mikrobiologi

   Författare :Kevin Bertilsson; [2024]
   Nyckelord :Lignin; Green plastic; Vanillin; Microbial production; Applied microbiology; Biology and Life Sciences;

   Sammanfattning : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. LÄS MER
