1. 16. Peers, Privacy & Pleasure: A mapping of how social norms influence consumers in their diffusion of a social media application with privacy implications, the case of TikTok

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Axel Fohlin; Carl Klittmar; [2023-07-03]
   Nyckelord :Social Norms; Injunctive Norms; Descriptive Norms; Personal Norms; Privacy Implication; Privacy Concern; Privacy Risk; Diffusion of Innovation; TikTok;

   Sammanfattning : TikTok, the social media network where users can post and share user created content with one another, has fallen under examination of governments across the globe due to rising distress in regards to the privacy implications that the app may have. Understanding how TikTok reached such success even with an apparent privacy implication calls for a mapping of the social norms (Injunctive, Descriptive, Personal) and how they shaped consumer perceptions.

3. 17. Air quality around preschools in Gothenburg: an evaluation of measurement methods

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Emma Forsmalm; [2023-06-21]
   Nyckelord :low-cost sensors; passive diffusion samplers; pick-ups and drop-offs; regulatory measurements;

   Sammanfattning : In this study the air quality around four different preschools, chosen to represent different local traffic environments, was measured and the measurement methods used were evaluated. The aim was to compare the information retrieved using different methods, discuss the possible applications of them and finally see if more specific activities, in this case pick-ups and drop-offs, could be seen in the data retrieved.

4. 18. Preprocessing for intravoxel incoherent motion analysis in the brain - Signal drift correction

   Master-uppsats,

   Författare :Amina Warsame; [2023-04-17]
   Nyckelord :Medical physics; Diffusion magnetic resonance imaging; dMRI; Intravoxel incoherent motion; IVIM;

   Sammanfattning : Diffusion magnetic resonance imaging (dMRI) is a diagnostic imaging technique that is sensitized to the movement of water molecules in tissues. Intravoxel incoherent motion (IVIM) analysis can be used to estimate blood flow in capillaries from weakly diffusion-weighted data. LÄS MER

5. 19. Image-driven simulation of brain tumors using a reaction-diffusion mathematical model

   Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

   Författare :Kristos Qiqi; [2023]
   Nyckelord :brain tumor; cancer; mathematical model; simulation; magnetic resonance images; hjärntumör; cancer; matematisk model; simulering; magnetresonanstomografi bilder;

   Sammanfattning : Brain tumors pose a big challenge in the field of neuro-oncology. Gliomas are the largest subgroup. Magnetic resonance imaging is a non-invasive tool for detecting and characterizing these tumors. Mathematical models, such as the reaction-diffusion equation, can be used for understanding the intricate behavior of gliomas. LÄS MER

7. 20. Framgångsrik implementering av ny teknik och AI : En kvalitativ undersökning av svenska myndigheters effektiviseringsarbeten med chattbots i kundtjänsten

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

   Författare :Maja Markiewicz; [2023]
   Nyckelord :Chatbot; Socioteknisk systemdesign; Innovationer; Implementering; Organisatorisk tröghet; Förändringsledning;

   Sammanfattning : The following thesis investigates how Transportstyrelsen, a Swedish authority, can use chatbots in their customer service to increase effectivity, save resources and be more available to their customers. Therefore, this report aims to map the effects a chatbot-implementation would have on Transportstyrelsen’s business and what technical and organisational factors that contribute to a successful implementation of the chatbot.
