1. 1. Analysis of Flow Prolongation Using Graph Neural Network in FIFO Multiplexing System

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

   Författare :Weiran Wang; [2023]
   Nyckelord :Network Calculus; Flow Prolongation; Graph Neural Network; Fast Gradient Sign Method; Delay Bound; Nätverkskalkyl; Flödesförlängning; Graph Neural Network; Fast Gradient Sign Method; Fördröjningsgräns;

   Sammanfattning : Network Calculus views a network system as a queuing framework and provides a series of mathematical functions for finding an upper bound of an end-to-end delay. It is crucial for the design of networks and applications with a hard delay guarantee, such as the emerging Time Sensitive Network. LÄS MER

3. 2. Scenario Generation for Stress Testing Using Generative Adversarial Networks : Deep Learning Approach to Generate Extreme but Plausible Scenarios

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

   Författare :Jonas Gustafsson; Conrad Jonsson; [2023]
   Nyckelord :Machine Learning; Generative Adversarial Network GAN ; Wasserstein Generative Adversarial Network WGAN ; Scenario Generation; Stress Testing; Central Counterparty Clearing;

   Sammanfattning : Central Clearing Counterparties play a crucial role in financial markets, requiring robust risk management practices to ensure operational stability. A growing emphasis on risk analysis and stress testing from regulators has led to the need for sophisticated tools that can model extreme but plausible market scenarios. LÄS MER

4. 3. The Effect of Air Pollution, Meteorology and HumanMobility on the Mortality of COVID-19 in Ecuador

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Oscar Xavier Gómez Manotoa; [2022]
   Nyckelord :;

   Sammanfattning : COVID-19 have caused a global pandemic that has taken the lives of millions. This studyexamines factors that contribute or inhibit its contagious nature. It is considered for the analysisfeatures of three groups: air pollutants, meteorological measurements and human mobilityindices. LÄS MER

5. 4. Gamma Knife treatment planning with new degrees of freedom

   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Emil Norell; [2019]
   Nyckelord :Stereotactic radiosurgery; Leksell Gamma Knife®; inverse planning; clustering; optimization; column generation; Stereotaktisk radiokirurgi; strålkniven; inversplanering; klustring; optimering; kolumn-generering;

   Sammanfattning : The Leksell Gamma Knife® is an instrument designed for high precision treatment of tumours and lesions located in the brain and upper spine. Today, the radioactive cobalt-60 sources can only move linearly along the radiation unit, but the machine could be modified to include rotational motion as well. LÄS MER

7. 5. Robust optimisation of the pressure-gradient distribution in turbulent boundary layers

   Master-uppsats, KTH/Mekanik

   Författare :Yuki Morita; [2019]
   Nyckelord :;

   Sammanfattning : In order to better characterise pressure-gradient turbulent boundary layers (TBLs), and to advance the theory of these flows, typically canonical conditions are required. This is achieved by keeping the Clauser pressure-gradient parameter, β, constant along the streamwise direction, see for instance Mellor and Gibson [9] and Bobke et al. LÄS MER
