1. 11. First cycle, 15 credits Machine Learning based Clustering of Bank Card Consumers : Identification of risk groups for fraud detection purposes

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jacob Hernberg; Ali Cicek; [2022]
   Nyckelord :;

   Sammanfattning : To safeguard consumers, banks have developed machine learning based fraud detections systems which work to prevent fraudulent card transactions from occurring. The goal of this report is to improve these systems by trying to segment consumers into different risk groups. LÄS MER

3. 12. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Max Eichenberger; [2022]
   Nyckelord :Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

   Sammanfattning : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

4. 13. Distillation or loss of information? : The effects of distillation on model redundancy

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Eva Elzbieta Sventickaite; [2022]
   Nyckelord :distillation; distillation effects; distilbert; distilmbert; distilroberta; distilgpt-2; distilled neurons; redundancy; redundancy in neural networks; redundancy in language models; neuron reduction in language models; distilled language models;

   Sammanfattning :     The necessity for billions of parameters in large language models has lately been questioned as there are still unanswered questions regarding how information is captured in the networks. It could be argued that without this knowledge, there may be a tendency to overparametarize the models. LÄS MER

5. 14. Cryptocurrencies future carbon footprint : An exploratory scenario analysis of cryptocurrencies' future energy consumption and carbon emission.

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Jacob Tunberg; [2022]
   Nyckelord :Cryptocurrencies; sustainability; energy consumption; carbon emission; Proof of Work; Proof of Stake.; Kryptovalutor; Hållbarhet; Elkonsumtion; Koldioxidutsläpp; Proof of Work Proof of Stake.;

   Sammanfattning : Since the creation of Bitcoin, the virtual currency has attracted the attention of many people and is now a household name synonymous with cryptocurrencies. Today, many thousands of different variants of cryptocurrencies exist, and more are being launched each day. LÄS MER

7. 15. Tillverkningsprocessen i industriell verksamhet - Gränsdragningsproblematik

   Kandidat-uppsats, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

   Författare :Rasmus Bengtsson; [2022]
   Nyckelord :skatterätt; tillverkningsprocessen; industriell verksamhet; Law and Political Science;

   Sammanfattning : The purpose of this essay is to examine the boundary problem with a non-legislated categorization concept. The concept of the manufacturing process in industrial activity is somewhat of a gray area, as it has never had a legis-lated definition and the scope of the concept has changed over time in dif-ferent ways.
