1. 1. Stochastic Frank-Wolfe Algorithm : Uniform Sampling Without Replacement

   Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

   Författare :Olof Håkman; [2023]
   Nyckelord :Stochastic Frank-Wolfe; Stochastic optimization; Sampling without replacement;

   Sammanfattning : The Frank-Wolfe (FW) optimization algorithm, due to its projection free property, has gained popularity in recent years with typical application within the field of machine learning. In the stochastic setting, it is still relatively understudied in comparison to the more expensive projected method of Stochastic Gradient Descent (SGD). LÄS MER

3. 2. Optimal simultaneous excitation for identification of multivariable systems

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

   Författare :Gunnar Sigurðsson; [2023]
   Nyckelord :System identification; Simultaneous excitation; Experiment design; Model Predictive Control MPC ; Optimization; Multivariable systems; Systemidentifiering; Simultan excitation; Experimentdesign; Modell Predictive Control MPC ; Optimering; Multivariabla system;

   Sammanfattning : Having a accurate model of a system is essential for many applications today, especially those related to advanced process control. When executing a project often a lot of time is spent performing experiments on the real system to estimate a model. LÄS MER

4. 3. Autophagy and senescence in primary human bronchial epithelial cells in the context of COPD

   Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

   Författare :Annie Vegraeus; [2023]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : Chronic obstructive pulmonary disease (COPD) is the third largest cause of death worldwide, with its most prominent risk factor being inhalation of smoke and pollutants. In this project, we studied two processes that are involved in COPD: autophagy and cellular senescence. LÄS MER

5. 4. Gamification Otherwise : Alternative directions to enhance the sense of friendliness in online communities

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

   Författare :Anna Chuprina; [2023]
   Nyckelord :gamification; sense of community; engagement; social media; gamification; känslan av gemenskap; engagemang; sociala medier;

   Sammanfattning : Gamification is a widely explored topic in various contexts. In particular, gamification is used in the form of likes and reactions on various social media. However, it was identified that this reward system in the form of likes led to addictive behavior. LÄS MER

7. 5. Towards the Development of Design Guidelines for Short Alert Sounds in a Retail Environment

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

   Författare :Gustav Frisk Arfvidsson; [2021]
   Nyckelord :;

   Sammanfattning : The design and noticeability of alert sounds have been widely researched and reported, furthermore, notification sounds are ubiquitous in both software and hardware product development. In an ongoing research project concerning the retail industry, we aim at designing short alert sounds that only grab attention from one group of customers, while others do not register the alerts: this particular aspect has to our knowledge not yet been studied.
