1. 1. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Antoni Eritja Olivella; [2024]
   Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

   Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER

3. 2. Classifying femur fractures using federated learning

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Hong Zhang; [2024]
   Nyckelord :Atypical femur fracture; Federated Learning; Neural Network; Classification;

   Sammanfattning : The rarity and subtle radiographic features of atypical femoral fractures (AFF) make it difficult to distinguish radiologically from normal femoral fractures (NFF). Compared with NFF, AFF has subtle radiological features and is associated with the long-term use of bisphosphonates for the treatment of osteoporosis. LÄS MER

4. 3. Profile Based Access Control Model Using JSON Web Tokens

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Mustafa Albayati; Aslan Murjan; [2023]
   Nyckelord :access control; profiles; IoT; device; OpenIDC; Technology and Engineering;

   Sammanfattning : Currently at Axis, a local role-based access control system is used in devices, which forces the user credentials to be directly installed on the individual devices and the limited selection of roles does not allow for fine-grained access rights. This creates an administrative nightmare in a large scale network and leads to elevated privileges. LÄS MER

5. 4. Parents’ perceptions about preschool children’s use of mobile devices and experiences at art museums

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Sooyoun Kim; [2023]
   Nyckelord :preschool children; mobile devices; tablets; educational apps; child-computer interaction; art museums; museum learning;

   Sammanfattning : The child–environment interaction type, which involves touching and handling part of collections and displays, is less common in art museums. In addition, art museums demand many behavioural rules from their visitors. The adult caregivers, therefore, prefer that their preschool children participate in child-friendly activity programmes.

7. 5. Effective learning in higher education post-covid_final version.

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Maria Maofi; [2023]
   Nyckelord :Online learning; Digital transformation; Post covid-19 effect; Next generation e-learning platform; Higher Education;

   Sammanfattning : The emergence of moving learning activities online, due to Covid-19 pandemic preventive measures and fast growing technology, forced many educational institutions to design and prepare their distance learning systems on time, without adopting the best practices for an effective and holistic digital transformation. This fact highlights the need of reconsidering the models in online learning and redesigning the learning processes to meet students e-learning needs and receive a more qualitative educational experience.
