1. 1. Applications of diffusion MRI: Tensor-valued encoding, time-dependent diffusion, and histological validation

   Författare :Jan Brabec; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diffusion MRI; meningioma; glioma; brain tumors; intracranial tumors; undulations; restricted diffusion; time dependence; spherical b-tensor encoding; linear b-tensor encoding; histogram analysis; anisotropic kurtosis; isotropic kurtosis; hyperintensity; conspicuity; white matter; detection; diffusion spectrum; consistency; type; grade; axon diameter; axonal trajectories; Fysicumarkivet A:2022:Brabec;

   Sammanfattning : Diffusion MRI (dMRI) sensitizes the MR signal to the diffusion of water molecules at the microscopic level and thereby non-invasively probes tissue microstructure. This is relevant when determining biological properties of tissues, for example, cancer type and its malignancy. LÄS MER

4. 3. Consistency and efficiency in continuous-time system identification

   Författare :Rodrigo A. González; Cristian R. Rojas; Bo Wahlberg; Hugues Garnier; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Continuous-time systems; Consistency; Asymptotic efficiency; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Continuous-time system identification deals with the problem of building continuous-time models of dynamical systems from sampled input and output data. In this field, there are two main approaches: indirect and direct. In the indirect approach, a suitable discrete-time model is first determined, and then it is transformed into continuous-time.

5. 4. Management of Real-Time Data Consistency and Transient Overloads in Embedded Systems

   Författare :Thomas Gustafsson; Jörgen Hansson; Ming Xiong; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; Real-time databases; Embedded systems; Similarity; Transient overloads; Computer science; Datalogi;

   Sammanfattning : This thesis addresses the issues of data management in embedded systems' software. The complexity of developing and maintaining software has increased over the years due to increased availability of resources, e.g., more powerful CPUs and larger memories, as more functionality can be accommodated using these resources.

7. 5. Individual consistency in bird migration

   Författare :YANNIS VARDANIS; Evolutionär ekologi; []
   Nyckelord :bird migration; telemetry; bird ringing; individual consistency; repeatability; site fidelity; routes; timing; annual cycle; meta-analysis;

   Sammanfattning : Slight differences, which appear in the individual animals of the same species and population have been recognised and appreciated ever since Darwin. These consistent intra-specific differences in animals have been considered very important because they are often inherited, and thus, provide the basic material for evolution to act on. LÄS MER
