3. 12. Towards safe and efficient application of deep neural networks in resource-constrained real-time embedded systems

   Författare :Siyu Luan; Zonghua Gu; Leonid B. Freidovich; Lei Feng; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Machine Learning Deep Learning; Real-Time Embedded systems; Out-of-Distribution Detection; Distribution Shifts; Deep Reinforcement Learning; Model Compression; Policy Distillation.;

   Sammanfattning : We consider real-time safety-critical systems that feature closed-loop interactions between the embedded computing system and the physical environment with a sense-compute-actuate feedback loop. Deep Learning (DL) with Deep Neural Networks (DNNs) has achieved success in many application domains, but there are still significant challenges in its application in real-time safety-critical systems that require high levels of safety certification under significant hardware resource constraints.

   Sammanfattning : Earth Observation (EO) satellites have great potential in wildfire detection and assessment at fine spatial, temporal, and spectral resolutions. For a long time, satellite data have been employed to systematically monitor wildfire dynamics and assess wildfire impacts, including (i) to detect the location of actively burning spots, (ii) to map the spatial extent of the burn scars, (iii) to assess the wildfire damage levels.

5. 14. Methods for deep examination of DNA

   Författare :Mårten Neiman; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :massive parallel sequencing;

   Sammanfattning : The development of sequencing technology has had a rapid pace during the last years and today, the sequencing instruments harbors enormous capacity. This thesis is about the development of methods to make the most out of this capacity and to use it for various applications. LÄS MER

7. 15. Deep Levels in Electron-Irradiated and As-Grown SiC Power Device Material

   Författare :Carl Hemmingsson; Gerhard Pensl; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Silicon Carbide (SiC) has several favorable physical properties for the fabrication of highpower, high-temperature and high-frequency devices. Devices in SiC can operate at high temperatures due to the wide band gap and the high thermal stability of the material. LÄS MER
